Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Follitropin beta, a recombinant form of human follicle-stimulating hormone (FSH), binds to the FSH receptor on ovarian granulosa cells and testicular Sertoli cells, stimulating follicular development and maturation in women and spermatogenesis in men.
OVIDREL (choriogonadotropin alfa) acts as a luteinizing hormone (LH) agonist, binding to the LH/choriogonadotropin receptor on ovarian theca and granulosa cells, triggering ovulation and luteinization by inducing resumption of oocyte meiosis and follicle rupture.
For ovulation induction: 75-150 IU subcutaneously or intramuscularly once daily for 7-12 days; for spermatogenesis: 75-150 IU subcutaneously or intramuscularly 3 times per week.
250 mcg subcutaneously once daily for 7 days following recombinant FSH stimulation. Alternatively, a single 250 mcg subcutaneous dose is used to trigger final follicular maturation 24-48 hours after last gonadotropin dose.

Terminal elimination half-life is approximately 24-36 hours in patients with normal renal function, supporting once-daily dosing.
The terminal elimination half-life is approximately 30 hours (range 20-48 hours) in healthy adults. This supports a single-dose regimen for final follicular maturation in assisted reproductive technology.
Primarily renal excretion of unchanged drug (80-90% of administered dose), with the remainder excreted as metabolites in urine and feces.
Primarily renal, with approximately 10% of the administered dose excreted unchanged in urine within 24 hours. The remainder undergoes metabolic degradation in the kidneys and liver.
