1.1 Induction of ovulation and pregnancy in oligo-anovulatory infertile women for whom the cause of infertility is functional and not due to primary ovarian failure.

1.2 Development of multiple follicles in ovulatory infertile women as part of an assisted reproductive technology (ART) cycle.

1.3 Induction of spermatogenesis in infertile men with primary and secondary hypogonadotropic hypogonadism for whom the cause of infertility is not due to primary testicular failure.

2.1 Important Dosage and Administration Information

Only physicians who are experienced in infertility treatment, should treat women with GONAL-F. GONAL-F is a gonadotropins product capable of causing in women, Ovarian Hyperstimulation Syndrome (OHSS) with or without pulmonary or vascular complications [see Warnings and Precautions (5.2, 5.3)] and multiple births [see Warnings and Precautions (5.6)]. Gonadotropin therapy requires the availability of appropriate monitoring facilities [see Warnings and Precautions (5.11)]. Use the lowest effective dose of GONAL-F.

Give careful attention to the diagnosis of infertility and the selection of candidates for GONAL-F therapy [see Dosage and Administration (2.3, 2.4)].

2.2 Preparation of GONAL-F and Selection of Injection Site

• Store lyophilized multiple-dose vials refrigerated or at room temperature (2°-25°C /36°-77°F) and protected from light.
• Prior to administration, parenteral drug products should be inspected visually for particulate matter and discoloration, whenever solution and container permit.
• Instruct women and men to use the accompanying syringes, calibrated in International Units FSH for administration. The 27-gauge injection syringe (see figure below) has unit dose markings from 37.5 International Units to 600 International Units FSH for use with GONAL-F Multi-Dose. Instruct women and men to take a specific dose of GONAL-F Multi-Dose. Show women and men how to locate the syringe marking that corresponds to the prescribed dose.
  
  
• Each GONAL‑F Multi‑Dose Vial delivers 450 International Units or 1050 International Units of follitropin alfa, respectively
  • Multi-Dose 450 International Units Vial:
    • Dissolve the contents of one Multi-Dose vial (450 International Units) with 1 mL Bacteriostatic Water for Injection (0.9% benzyl alcohol), USP. Resulting concentration will be 600 International Units/mL. Following reconstitution as directed, product will deliver the equivalent of six 75 International Units doses.
  • Multi-Dose 1050 International Units Vial:
    • Dissolve the contents of one Multi-Dose vial (1050 International Units) with 2 mL Bacteriostatic Water for Injection (0.9% benzyl alcohol), USP. Resulting concentration will be 600 International Units/mL. Following reconstitution as directed, product will deliver the equivalent of fourteen 75 International Units doses.
• Discard unused reconstituted solution after 28 days.
• Administer GONAL-F subcutaneously in the abdomen, upper arm, or upper leg as described in Patient Information and Instructions for Use.

2.3 Dosing for Ovulation Induction

Prior to initiation of treatment with GONAL-F:

• Perform a complete gynecologic and endocrinologic evaluation
• Exclude primary ovarian failure
• Exclude the possibility of pregnancy
• Demonstrate tubal patency
• Evaluate the fertility status of the male partner

The dosing scheme is stepwise and is individualized for each woman [see Clinical Studies (14.1)].

• Administer a starting dose of 75 International Units of GONAL-F subcutaneously daily for 14 days in the first cycle of use.
• In subsequent cycles of treatment, determine the starting dose (and dosage adjustments) of GONAL-F based on the woman's history of the ovarian response to GONAL-F.
• If indicated by the ovarian response after the initial 14 days, make an incremental adjustment in dose of up to 37.5 International Units.
• If indicated by the ovarian response, make additional incremental adjustments in the dose, up to 37.5 International Units, every 7 days.
• Continue treatment until follicular growth and/or serum estradiol levels indicate an adequate ovarian response.
• Consider the following when planning the woman's individualized dose:
  • Use the lowest dose of Gonal-F consistent with the expectation of good results.
  • Use appropriate GONAL-F dose adjustment(s) to prevent multiple follicular growth and cycle cancellation.
  • The maximum, individualized, daily dose of GONAL-F is 300 International Units per day.
  • In general, do not exceed 35 days of treatment, unless an estradiol rise indicates imminent follicular development.
• When pre-ovulatory conditions are reached, administer human chorionic gonadotropin (hCG) to induce final oocyte maturation and ovulation. Human chorionic gonadotropin, hCG, (5,000 USP units) should be given 1 day after the last dose of GONAL-F.
• Encourage the woman and her partner to have intercourse daily, beginning on the day prior to the administration of hCG and until ovulation becomes apparent.
• Withhold hCG in cases where the ovarian monitoring suggests an increased risk of ovarian hyperstimulation syndrome (OHSS) on the last day of GONAL-F therapy (for example estradiol greater than 2,000 pg per mL) [see Warnings and Precautions (5.2, 5.3, 5.5, 5.11)].
  • Discourage intercourse when the risk for OHSS is increased [see Warnings and Precautions (5.2, 5.5)].
• Schedule a follow-up visit in the luteal phase.
• Individualize the initial dose administered in subsequent cycles based on the woman's response in the preceding cycle.
• As in the initial cycle, do not administer doses larger than 300 International Units of FSH per day. Administer 5,000 USP units of hCG 1 day after the last dose of GONAL-F to complete follicular development and induce ovulation.
• Follow the above recommendations to minimize the chance of development of OHSS.

2.4 Dosing for Multiple Follicle Development as part of an Assisted Reproductive Technology (ART) Cycle

Prior to initiation of treatment with GONAL-F:

• Perform a complete gynecologic and endocrinologic evaluation, and diagnose the cause of infertility
• Exclude the possibility of pregnancy
• Evaluate the fertility status of the male partner

The dosing scheme follows a stepwise approach and is individualized for each woman.

• Beginning on cycle day 2 or 3, administer subcutaneously a starting dose of 150 International Units of GONAL-F daily until sufficient follicular development, as determined by ultrasound in combination with measurement of serum estradiol levels, is attained. In most cases, therapy should not exceed ten days.
• In women whose endogenous gonadotropin levels are suppressed, initiate GONAL-F administration at a dose of 225 International Units per day.
• Adjust the dose after 5 days based on the woman's ovarian response, as determined by ultrasound evaluation of follicular growth and serum estradiol levels.
• Do not make additional dosage adjustments more frequently than every 3-5 days or by more than 75-150 International Units at each adjustment.
• Continue treatment until adequate follicular development is evident, and then administer hCG (5,000 to 10,000 USP units) to induce final follicular maturation in preparation for oocyte retrieval.
• Withhold hCG administration in cases where the ovarian monitoring suggests an increased risk of OHSS on the last day of GONAL-F therapy [see Warnings and Precautions (5.2, 5.3, 5.4, 5.11)].
• Do not use doses greater than 450 International Units per day.

2.5 Dosing for Induction of Spermatogenesis in Males with Azoospermia and Primary or Secondary Hypogonadotropic Hypogonadism:

Prior to initiation of treatment with GONAL-F:

• Confirm azoospermia
• Perform a thorough medical and endocrinologic evaluation to exclude other treatable etiologies of azoospermia
• Confirm hypogonadotropic hypogonadism
• Exclude primary testicular failure
• Normalize serum testosterone levels

The dosing scheme follows a stepwise approach and is individualized for each man.

• GONAL-F must be given in conjunction with hCG.
• Prior to concomitant therapy with GONAL-F and hCG, pretreatment with hCG alone (1,000 to 2,250 USP units two to three times per week) is required to normalize serum testosterone levels.
• Treatment with hCG alone should continue until serum testosterone levels reach the normal range, which may take 3 to 6 months. The dose of hCG may also need to be increased during this time to achieve normal serum testosterone levels.
• After serum testosterone levels have normalized, administer GONAL-F 150 International Units subcutaneously three times a week and hCG 1,000 USP units (or the dose required to maintain serum testosterone levels within the normal range) three times a week. The lowest dose of GONAl-F which induces spermatogenesis should be utilized.
• If azoospermia persists, increase the dose of GONAL-F up to a maximum dose of 300 International Units three times per week. Administer GONAL-F for up to 18 months to achieve adequate spermatogenesis.

2.6 Missed Dose

Do not double the next dose if a woman or a man misses or forgets to take a dose of GONAL-F.

5.1 Hypersensitivity Reactions and Anaphylaxis

In the postmarketing experience, serious systemic hypersensitivity reactions, including anaphylaxis, have been reported with use of GONAL-F and GONAL-F RFF. Symptoms have included dyspnea, facial edema, pruritis, and urticaria. If an anaphylactic or other serious allergic reaction occurs, initiate appropriate therapy including supportive measures if cardiovascular instability and/or respiratory compromise occur, and discontinue further use.

5.2 Ovarian Hyperstimulation Syndrome (OHSS)

Ovarian Hyperstimulation Syndrome (OHSS) is a medical entity distinct from uncomplicated ovarian enlargement and may progress rapidly to become a serious medical event. OHSS is characterized by a dramatic increase in vascular permeability, which can result in a rapid accumulation of fluid in the peritoneal cavity, thorax, and potentially, the pericardium. The early warning signs of development of OHSS are severe pelvic pain, nausea, vomiting, and weight gain. Abdominal pain, abdominal distension, gastrointestinal symptoms including nausea, vomiting and diarrhea, severe ovarian enlargement [see Warnings and Precautions (5.6)], weight gain, dyspnea, and oliguria have been reported with OHSS. Clinical evaluation may reveal hypovolemia, hemoconcentration, electrolyte imbalances, ascites, hemoperitoneum, pleural effusions, hydrothorax, acute pulmonary distress, and thromboembolic reactions [see Warnings and Precautions (5.4)]. Transient liver function test abnormalities suggestive of hepatic dysfunction with or without morphologic changes on liver biopsy, have been reported in association with OHSS.

OHSS occurs after gonadotropin treatment has been discontinued and it can develop rapidly, reaching its maximum about seven to ten days following treatment. Usually, OHSS resolves spontaneously with the onset of menses. If there is evidence that OHSS may be developing prior to hCG administration [see Dosage and Administration (2.2, 2.3)], withhold hCG. Cases of OHSS are more common, more severe, and more protracted if pregnancy occurs; therefore, assess women for the development of OHSS for at least two weeks after hCG administration.

If serious OHSS occurs, stop gonadotropins, including GONAL-F and hCG, and consider whether the woman needs to be hospitalized. Treatment is primarily symptomatic and overall consists of bed rest, fluid and electrolyte management, and analgesics (if needed). Because the use of diuretics can accentuate the diminished intravascular volume, avoid diuretics except in the late phase of resolution as described below. The management of OHSS is divided into three phases as follows:

• Acute Phase:
  Management is directed at preventing hemoconcentration due to loss of intravascular volume to the third space and minimizing the risk of thromboembolic phenomena and kidney damage. Thoroughly assess daily or more often, based on the clinical need, fluid intake and output, weight, hematocrit, serum and urinary electrolytes, urine specific gravity, BUN and creatinine, total proteins with albumin: globulin ratio, coagulation studies, electrocardiogram to monitor for hyperkalemia, and abdominal girth. Treatment, consisting of limited intravenous fluids, electrolytes, human serum albumin, is intended to normalize electrolytes while maintaining an acceptable but somewhat reduced intravascular volume. Full correction of the intravascular volume deficit may lead to an unacceptable increase in the amount of third space fluid accumulation.
• Chronic Phase:
  After the acute phase is successfully managed as above, excessive fluid accumulation in the third space should be limited by instituting severe potassium, sodium, and fluid restriction.
• Resolution Phase:
  As third space fluid returns to the intravascular compartment, a fall in hematocrit and increasing urinary output are observed in the absence of any increase in intake. Peripheral and/or pulmonary edema may result if the kidneys are unable to excrete third space fluid as rapidly as it is mobilized. Diuretics may be indicated during the resolution phase, if necessary, to combat pulmonary edema.
  
  Do not remove ascitic, pleural, and pericardial fluid, unless there is the necessity to relieve symptoms such as pulmonary distress or cardiac tamponade.

OHSS increases the risk of injury to the ovary. Avoid pelvic examination or intercourse, as these may cause rupture of an ovarian cyst, which may result in hemoperitoneum.

If bleeding occurs and requires surgical intervention, control the bleeding and retain as much ovarian tissue as possible. A physician experienced in the management of this syndrome, or who is experienced in the management of fluid and electrolyte imbalances should be consulted.

5.3 Pulmonary and Vascular Complications

Serious pulmonary conditions (for example, atelectasis, acute respiratory distress syndrome and exacerbation of asthma) have been reported in women treated with gonadotropins, including GONAL-F. In addition, thromboembolic events both in association with, and separate from OHSS have been reported in women treated with gonadotropins, including GONAL-F. Intravascular thrombosis and embolism, which may originate in venous or arterial vessels, can result in reduced blood flow to critical organs or the extremities. Women with generally recognized risk factors for thrombosis, such as personal or family history, severe obesity, or thrombophilia, may have an increased risk of venous or arterial thromboembolic events, during or following treatment with gonadotropins. Sequelae of such reactions have included venous thrombophlebitis, pulmonary embolism, pulmonary infarction, cerebral vascular occlusion (stroke), and arterial occlusion resulting in loss of limb and rarely in myocardial infarctions. In rare cases, pulmonary complications and/or thromboembolic reactions have resulted in death. In women with recognized risk factors, the benefits of ovulation induction and Assisted Reproductive Technology (ART) need to be weighed against the risks. It should be noted that pregnancy also carries an increased risk of thrombosis.

5.4 Ovarian Torsion

Ovarian torsion has been reported after treatment with gonadotropins, including GONAL-F. This may be related to OHSS, pregnancy, previous abdominal surgery, past history of ovarian torsion, previous or current ovarian cyst and polycystic ovaries. Early diagnosis and immediate detorsion limit damage to the ovary due to reduced blood supply.

5.5 Abnormal Ovarian Enlargement

In order to minimize the hazards associated with abnormal ovarian enlargement that may occur with GONAL-F therapy, individualize treatment and use the lowest effective dose [see Dosage and Administration (2.2, 2.3)]. Use of ultrasound monitoring of ovarian response and/or measurement of serum estradiol levels is important to minimize the risk of ovarian stimulation [see Warnings and Precautions (5.12)].

If the ovaries are abnormally enlarged on the last day of GONAL-F therapy, do not administer hCG in order to reduce the chance of developing Ovarian Hyperstimulation Syndrome (OHSS) [see Warnings and Precautions (5.2)]. Prohibit intercourse for women with significant ovarian enlargement after ovulation because of the danger of hemoperitoneum resulting from rupture of ovarian cysts [see Warnings and Precautions (5.2)].

5.6 Multi-fetal Gestation and Birth

Multi-fetal gestation and births have been reported with all gonadotropin therapy, including therapy with GONAL-F.

During clinical trials with GONAL-F, multiple births occurred in 20% of live births in women receiving therapy for ovulation induction and 35.1% of live births in women undergoing ART. Advise the woman and her partner of the potential risk of multi-fetal gestation and birth before beginning therapy with GONAL-F.

5.7 Embryofetal toxicity

The incidence of congenital malformations after some ART [specifically in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)] may be slightly higher than after spontaneous conception. This slightly higher incidence is thought to be related to differences in parental characteristics (e.g., maternal age, maternal and paternal genetic background, sperm characteristics) and to the higher incidence of multi-fetal gestations after IVF or ICSI. There are no indications that the use of gonadotropins during IVF or ICSI is associated with an increased risk of congenital malformations.

5.8 Ectopic Pregnancy

Since infertile women undergoing ART often have tubal abnormalities, the incidence of ectopic pregnancy may be increased in women who become pregnant as a result of ART. Advise women who become pregnant following ART and have: abdominal/pelvic pain (particularly on one side); shoulder, neck or rectal pain; and nausea and vomiting to seek immediate medical attention. Confirm the presence of an intrauterine pregnancy early by β-hCG testing and transvaginal ultrasound.

5.9 Spontaneous Abortion

The risk of spontaneous abortion (miscarriage) is increased with gonadotropin products, including GONAL-F. However, causality has not been established. The increased risk may be a factor of the underlying infertility.

5.10 Ovarian Neoplasms

There have been infrequent reports of ovarian neoplasms, both benign and malignant, in women who have had multiple drug therapy for controlled ovarian stimulation, however, a causal relationship has not been established.

5.11 Laboratory Tests

In most instances, treatment of women with GONAL-F will result only in follicular recruitment and development. In the absence of an endogenous LH surge, hCG is given to trigger ovulation when monitoring of the woman indicates that sufficient follicular development has occurred. This may be estimated by ultrasound alone or in combination with measurement of serum estradiol levels. The combination of both ultrasound and serum estradiol measurement are useful for monitoring follicular growth and maturation, timing of the ovulatory trigger, detecting ovarian enlargement and minimizing the risk of the OHSS and multiple gestation.

The clinical confirmation of ovulation is obtained by direct or indirect indices of progesterone production as well as sonographic evidence of ovulation.

Direct or indirect indices of progesterone production:

• Urinary or serum luteinizing hormone (LH) rise
• A rise in basal body temperature
• Increase in serum progesterone
• Menstruation following a shift in basal body temperature

Sonographic evidence of ovulation:

• Collapsed follicle
• Fluid in the cul-de-sac
• Features consistent with corpus luteum formation
• Secretory endometrium

6.1 Clinical Study Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice.

6.2 Postmarketing Experience

In addition to adverse events reported from clinical trials, the following adverse reactions have been reported during postmarketing use of GONAL-F. Because these reactions were reported voluntarily from a population of uncertain size, the frequency or a causal relationship to GONAL-F cannot be reliably determined.

Body as a Whole - General: Hypersensitivity reactions including anaphylaxis

Respiratory System: Asthma exacerbation

Vascular Disorders: Thromboembolism

8.1 Pregnancy

8.2 Lactation

There are no data on the presence of GONAL-F in human milk, the effects on the breastfed infant, or the effects on milk production. Because the secretion of prolactin during lactation can result in inadequate response to ovarian stimulation, advise women not to breast feed during treatment with GONAL-F.

8.3 Females and Males of Reproductive Potential

Because GONAL-F is not indicated in pregnant women, verify a negative pregnancy test before administering GONAL-F to a woman [see Dosage and Administration (2.3, 2.4)].

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Safety and effectiveness of GONAL-F in postmenopausal women have not been established and it is not indicated in this population.

12.1 Mechanism of Action

GONAL-F stimulates ovarian follicular growth in women who do not have primary ovarian failure. In order to bring about final maturation of the follicle and ovulation in the absence of an endogenous LH surge, human chorionic gonadotropin (hCG) must be given, following the administration of GONAL-F, when monitoring of the patient indicates that sufficient follicular development is achieved.

GONAL-F stimulates spermatogenesis in men with hypogonadotropic hypogonadism when administered with hCG.

12.2 Pharmacodynamics

Serum inhibin, estradiol, and total follicular volume responded as a function of time, with pronounced inter-woman variability in healthy volunteers administered GONAL-F. Pharmacodynamic effect lagged behind FSH serum concentration. Serum inhibin levels responded with the least delay and declined rapidly after discontinuation of GONAL-F. Follicular growth was most delayed and continued even after discontinuation of GONAL-F, and after serum FSH levels had declined. Maximum follicular volume correlated better with inhibin and estradiol peak levels than with FSH concentration. Inhibin rise was an early index of follicular development.

FSH serum levels following fixed (during the first five days) and then adjusted doses of GONAL-F were found to be poor predictors of follicular growth rate. High pre-treatment serum FSH levels may predict lower follicular growth rates.

Inhibin levels reached a plateau during the entire administration period and then returned to baseline despite high inter-male variation and the absence of down-regulation in healthy male volunteers administered GONAL-F.

12.3 Pharmacokinetics

Single dose and state-state pharmacokinetics of follitropin alfa were determined following subcutaneous administration of GONAL-F to healthy, down-regulated female volunteers, healthy adult male volunteers, and pituitary down-regulated women undergoing in vitro fertilization and embryo transfer (IVF/ET). The pharmacokinetic parameters of follitropin alfa following subcutaneous administration of GONAL-F are presented in Table 4.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long- term studies in animals have not been performed to evaluate the carcinogenic potential of GONAL-F. However, follitropin alfa showed no mutagenic activity in a series of tests performed to evaluate its potential genetic toxicity including, bacterial and mammalian cell mutation tests, a chromosomal aberration test and a micronucleus test.

Impaired fertility has been reported in rats, exposed to pharmacological doses of follitropin alfa (greater than or equal to 40 International Units per kg per day, greater than or equal to 5 times the lowest clinical dose of 75 International Units) for extended periods, through reduced fecundity.

14.1 Induction of Ovulation

The safety and efficacy of GONAL-F were examined in a randomized, open-label, multicenter, active-controlled trial conducted in the U.S in oligo-anovulatory infertile women. Women were randomized to GONAL-F , administered subcutaneously, or a comparator urofollitropin product, administered intramuscularly.

The primary efficacy parameter was the ovulation rate. Two hundred and thirty-two women received treatment for up to three cycles with GONAL-F (118 women ) or urofollitropin (114 women).

Ovulation results for women who received treatment with GONAL-F in at least one cycle are summarized in Table 5.

For the 44 woman in the GONAL-F group who achieved clinical pregnancy, 22.7 % did not reach a term pregnancy, 63.6% had singleton births and 13.7% had multiple births.

An additional randomized, open-label, multinational, multicenter trial, active-comparator trial was conducted in oligo-anovulatory infertile women who failed to ovulate or conceive following adequate clomiphene citrate therapy. Results for the primary efficacy outcome of cumulative percent ovulation at Cycle 1 were similar to those presented in Table 5 for the U.S. ovulation induction trial.

14.2 Development of Multiple Follicles as part of an Assisted Reproductive Technology (ART) Cycle:

The efficacy of GONAL-F in ART, was evaluated in a randomized,open-label, multicenter, active-controlled trial conducted ith the U.S, in ovulatory, infertile women undergoing stimulation of multiple follicles for In Vitro Fertilization (IVF) and Embryo Transfer (ET). All women received a gonadotrophin releasing hormone (GnRH) agonist for pituitary down-regulation before randomization and administration of GONAL-F (n=56) or a comparator urofollitropin product (n=58). The primary efficacy endpoint was the number of mature pre-ovulatory follicles on the day of hCG administration. The trial was not powered to demonstrate differences in secondary outcomes.

Treatment outcomes for a single IVF cycle with controlled stimulation with GONAL-F are summarized in Table 6.

For the 11 woman in the GONAL-F group who achieved clinical pregnancy, 36.3% did not reach a term pregnancy, 36.3% had singleton births and 27.3% had multiple births.

An additional randomized, open-label, multinational, multicenter study in ovulatory infertile women was conducted in non-U.S. countries. Women were randomized to receive either GONAL-F by subcutaneous administration (60 women) or urofollitropin by intramuscular administration (63 women) after down-regulation of the pituitary with a GnRH agonist. The primary efficacy parameter was the number of mature pre-ovulatory follicles on the day of hCG administration. Results over a single IVF cycle for the primary efficacy outcome of mature pre-ovulatory follicles on the day of hCG administration were similar to the primary efficacy results presented in Table 6 for the U.S.ART trial.

14.3 Induction of Spermatogenesis in Males

The efficacy of GONAL-F administered concomitantly with human chorionic gonadotropin (hCG) for induction of spermatogenesis in men with hypogonadotropic hypogonadism was established in three open-label, uncontrolled, non-randomized, multi-center, multi-national, escalating dose clinical trials (Trials 1, 2 and 3) conducted in 78 adult men (aged 16 to 48 years) with primary or secondary hypogonadotropic hypogonadism (defined as serum testosterone <100 ng/mL and low or normal FSH and LH) and azoospermia (sperm concentration <0.1×106/mL). Men were required at study entry to have normal serum cortisol and prolactin levels and be euthyroid. Men less than 21 years of age were required to have either confirmed anosmia or documented bone age >15 years to be eligible for study participation. Enrolled men received three to six months of pretreatment with hCG injection to normalize serum testosterone levels, followed by 18 months of treatment with GONAL-F and hCG.

Of the 78 men enrolled in the trials, 63 men were treated with GONAL-F and hCG.

Characteristics of the trial populations are shown in Table 7.

The primary efficacy measure in all trials was the proportion of men achieving a sperm density ≥ 1.5 × 106/mL during treatment with Gonal-F. Pregnancy (clinical and chemical) in partners of men desiring fertility was a secondary endpoint. Efficacy results in men who received at least one dose of Gonal-F and had at least one follow-up assessment are summarized in Table 8 and Table 9.

The time to achievement of sperm density ≥1.5 × 106/mL is summarized in Table 10.

Ovarian Hyperstimulation Syndrome

Inform women regarding the risks of OHSS [see Warnings and Precautions (5.2] and OHSS-associated conditions including pulmonary and vascular complications [see Warnings and Precautions (5.3)] and ovarian torsion [see Warnings and Precautions (5.4)] with the use of GONAL-F. Advise women to seek medical attention if any of these conditions occur.

Abnormal Ovarian Enlargement

Inform women regarding the hazards associated with abnormal ovarian enlargement that may occur with GONAL-F therapy. If the ovaries are abnormally enlarged on the last day of GONAL-F therapy, inform women not to administer hCG and to avoid intercourse [see Warnings and Precautions (5.5)].

Multi-fetal Gestation and Birth

Advise the woman and her partner of the potential risk of multi-fetal gestation and birth before beginning therapy withGONAL-F [see Warnings and Precautions (5.6)].

Embryofetal Toxicity

Inform women that the incidence of congenital malformations (birth defects) after some Assisted Reproductive Technology [(ART) specifically in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)] may be slightly higher than after spontaneous conception [see Warnings and Precautions (5.7)].

Ectopic Pregnancy

Inform women undergoing ART that the incidence of ectopic pregnancy may be increased with these procedures, particularly for women with tubal abnormalities. Advise women who become pregnant and have: abdominal/pelvic pain (particularly on one side); shoulder, neck or rectal pain; and nausea and vomiting to seek immediate medical attention [see Warnings and Precautions (5.8)].

Spontaneous Abortion

Inform women that the risk of spontaneous abortion (miscarriage) is increased with gonadotropin products (including GONAL-F). However, causality has not been established. The increased risk may be a factor of the underlying infertility [see Warnings and Precautions (5.9)].

Lactation

Advise women not to breastfeed because the secretion of prolactin during lactation can result in inadequate response to ovarian stimulation with Gonal-F [see Use in Specific Populations (8.2)].

Dosing and Use of GONAL-F Multi Dose

Instruct women and men on the correct usage and dosing of GONAL-F [see Dosage and Administration (2.3, 2.4 2.5)]. Caution against changing the dosage or the schedule of administration unless instructed to do so by a healthcare provider.

Duration and Necessary Monitoring in Patients Undergoing Therapy with GONAL-F

Prior to beginning therapy with GONAL-F, inform women and men about the time commitment and monitoring procedures necessary for treatment [see Dosage and Administration (2.3, 2.4, 2.5) and Warnings and Precautions (5.11)].

Instructions Regarding a Missed Dose

Inform women and men that if they miss or forget to take a dose of GONAL-F, they should not double the next dose and should call their healthcare provider for further dosing instructions.
