Ovulation Induction
Initial dose of first cycle: 75 IU SC qDay; after 14 days, increase dose by increments of up to 37.5 IU; further dose increases, as necessary every 7 days
Dose based on effect, with lowest effective dose; maximum recommended dose 300 International Units qDay
Treatment maximum of 35 days, unless E2 rise indicates imminent follicular developement
To complete follicular development in absence of endogenous LH surge, give chorionic gonadatropin (hCG)- 5000 units 1 day after last dose
Withhold if serum estradiol >2,000 pg/mL or if abnormal ovarian enlargement/abdominal pain
Advise patient against intercourse
Initial dose in subsequent cycles based on response in previous cycle
Advise daily intercourse beginning on day prior to hCG until ovulation apparent from lab tests
Assisted Reproductive Technologies
Initial dose on cycle day 2 or 3: 150 IU SC qDay until sufficient follicular development; typically does not exceed 10 days
If endogenous gonadotropin levels are suppressed, should be started at 225 IU qDay
Continue until adequate follicular development based on ultrasound and serum estradiol levels; dose adjustments of 75-150 IU may be made q3-5Days
Maximum recommended dose 450 IU qDay
Once adequate follicular development, administer hCG (5,000-10,000 USP); withhold if ovaries abnormally enlarged on last day of treatment
Male Patients with Hypogonadotropic Hypogonadism (Gonal-f Only)
Pretreat with hCG (1,000- 2,250 USP IU 2-3 x/week) until serum testosterone within normal range (may require 3-6 months of treatment)
Treatment consists of Gonal-f 150 IU SC 3 times/week used in conjunction with hCG
hCG 1000 USP Units (or dose to maintain normal serum testosterone levels) 3 x/week
If azoospermia persists, may increase dose to 300 IU 3 x/week
May need to administer for up to 18 months for adequate response

Sex hormone dependent tumors of the reproductive tract and accessory organs
Organic intracranial lesion (e.g. pituitary tumor)
Women with abnormal uterine bleeding of undetermined origin; ovarian cyst or enlargement of undetermined origin
Pregnancy
Cautions
May cause ovarian hyperstimulation syndrome (OHSS, dramatic increase in vascular permeability which can result in rapid fluid accumulation in peritoneal cavity, thorax and pericardium; accompanied by severe pelvic pain, nausea, vomiting and weight gain) in women with or without pulmonary or vascular complications
If ovaries are abnormally enlarged on last day of therapy, inform women not to administer hCG and to avoid intercourse
Pulmonary conditions (atelactasis, ARDS, & asthma exacerbation) have been reported; in women with recognized risk factors, the benefits of induction of ovulation and ART need to be weighed against risks; during or after use of drug, monitor for venous or arterial thromboembolic events
Possibility of multiple births (range 12.3%-44.0% live births)
In ovarian torsion, early diagnosis and immediate detorsion limit damage to ovary due to reduced blood supply
A thorough gynecologic & endocrinological evaluation should be conducted prior to treatment to rule out primary ovarian failure, early pregnancy & partner's fertility potential
The rate of multiple births is dependent on number of embryos transferred; advise the woman and her partner of the potential risk of multi-fetal gestation and birth before beginning therapy
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
The risk of spontaneous abortion (miscarriage) is increased with gonadotropin products, however, causality has not been established
Both benign and malignant ovarian neoplasms are reported in women who have had multiple drug therapy for controlled ovarian stimulation, however, causality has not been established
Pregnancy & Lactation
Pregnancy
Drug not indicated in pregnant women
The incidence of congenital malformations after some assisted reproductive technology, specifically in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI)], maybe slightly higher than that after spontaneous conception; this slightly higher incidence is thought to be related to differences in parental characteristics (eg, maternal age, maternal and paternal genetic background, sperm characteristics) and to a higher incidence of multi-fetal gestations after IVF or ICSI; there is no human data that the use of womens-health-reproduction#gonadotropins (including drug alone or as part of IVF or ICSI cycles, increases risk of congenital malformations
Risk of spontaneous abortion (miscarriage) is increased in women who have used womens-health-reproduction#gonadotropins products (including GONAL-F) to achieve pregnancy
Verify a negative pregnancy test before administering drug
Animal data
- In animal studies, the continuous administration of recombinant human FSH during pregnancy resulted in a decrease in number of viable fetuses and difficult and prolonged delivery; no teratogenic effect observed
Lactation
There are no data on presence of drug in human milk, effects on breastfed infant, or on milk production; because secretion of prolactin during lactation can result in inadequate response to ovarian stimulation, advise women not to breastfeed during treatment
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
