Usual Adult Dose for Ovulation Induction

Anovulatory Infertility:
Follitropin alpha:
Initial dose: 75 international units subcutaneously (SC) daily for 14 days
Maximum dose: 300 international units daily
Follitropin beta:
Initial dose: 50 international units SC daily for 7 days
Maximum dose: 250 international units daily
Duration of therapy: Until an adequate ovarian response is achieved

Comments:
-When pre-ovulatory condition is obtained, administer human chorionic gonadotropin (hCG) to induce final oocyte maturation and ovulation.
-Adequate ovarian response is assessed with serum estrogen concentrations and/or ultrasound examination.
-Withhold hCG when monitoring suggests an increased risk of Ovarian Hyperstimulation Syndrome (OHSS).
-Recommend daily intercourse, beginning the day prior to hCG administration and until ovulation becomes apparent.
-Discourage intercourse when the risk for OHSS is increased.
-If an excessive response is obtained, stop treatment and withhold hCG.
-In general, do not exceed 35 days of treatment.

Assisted Reproduction:
Follitropin alpha:
Initial dose: 150 international units SC daily for 5 days
Maximum dose: 450 international units daily
Follitropin beta:
Initial dose: 200 international units SC daily for 7 days
Maximum dose: 500 international units daily

Comments:
-When sufficient follicular development is obtained, as determined by ultrasound and estradiol levels, administer hCG.
-Withhold hCG when monitoring suggests an increased risk of OHSS.

Spermatogenesis:
Follitropin beta:
Initial dose: 225 international units SC twice a week; or 150 international units SC three times a week (total of 450 international units every week)

Comments:
-Pretreatment with hCG is required prior to concomitant therapy with follitropin beta and hCG.
-At least 3 to 4 months of concomitant therapy are needed before any improvement in spermatogenesis can be expected.
-Response to treatment may take up to 12 months.

Uses:
-Induction of ovulation and pregnancy in anovulatory women in whom the cause of infertility is functional and not due to primary ovarian failure.
-Development of multiple follicles in ovulatory women as part of an Assisted Reproductive Technology (ART) Cycle.
-Follitropin beta: Induction of spermatogenesis in men with primary and secondary Hypogonadotropic Hypogonadism (HH) in whom the cause of infertility is not due to primary testicular failure.

Dose Adjustments

Follitropin beta:
-The pen injector device delivers on average an 18% higher amount of follitropin beta when compared to a conventional syringe and needle.
-Consider a lower starting dose when using the pen.
-Switching brands (manufacturers), types (recombinant, urinary), and/or methods of administration (pen, conventional syringe) may require dose adjustment.

Ovulation induction:
-The dosing scheme is stepwise and is individualized for each woman.
-Use dose adjustments to prevent multiple follicular growth and cycle cancellation.
Follitropin alpha:
-Starting doses less than 37.5 international units have not been studied and are not recommended.
-After the first cycle, determine the starting dose and dosage adjustments based on ovarian response.
-If needed, after the initial 14 days, make incremental dose adjustments, up to 37.5 international units, every 7 days.
Follitropin beta:
-After the first cycle, make dose adjustments weekly intervals based upon ovarian response.
-Make adjustments by 25 or 50 international units at weekly intervals until follicular growth and/or serum estradiol levels indicate an adequate ovarian response.

Assisted Reproduction:
Follitropin alpha:
-In women aged 35 years or older whose endogenous gonadotropin levels are suppressed, initiate treatment at 225 international units subcutaneously daily for 5 days.
-Adjust the dose after the first 5 days based on ovarian response, as determined by ultrasound evaluation of follicular growth and serum estradiol levels.
-Do not adjust dose more than every 3 to 5 days or by more than 75 to 150 international units at each adjustment.
-In most cases, therapy should not exceed 10 days.
Follitropin beta:
-Adjust the dose after the first 7 days of treatment based on ovarian response, as determined by ultrasound evaluation of follicular growth and serum estradiol levels.
-For high responding women [those at particular risk of abnormal ovarian enlargement and/or ovarian hyperstimulation syndrome (OHSS)], decrease or temporarily stop the daily dose, or discontinue the cycle according to individual response.

Spermatogenesis:
-Based on delivery of a higher dose of follitropin beta with the pen injector, a lower dose may be considered.
