Is Pregnyl used for both male and female infertility?
Pregnyl (human chorionic gonadotropin, hCG) is used in both men and women for infertility treatment, but the reasons differ by sex. In women, it’s used in assisted reproduction protocols and ovulation induction settings where triggering ovulation is needed. In men, it’s used to treat certain causes of male infertility related to low gonadotropin signaling, such as hypogonadotropic hypogonadism, by stimulating testosterone production and supporting sperm development.
What role does Pregnyl play in women’s infertility treatment?
In female fertility care, Pregnyl is used as an ovulation trigger. It can be part of fertility regimens where the goal is to help a follicle release an egg at the right time for conception, including in assisted reproductive technologies.
What role does Pregnyl play in men’s infertility treatment?
In male fertility care, Pregnyl helps stimulate Leydig cells to produce testosterone, which supports spermatogenesis when the problem is due to inadequate luteinizing hormone (LH)-like stimulation. It’s commonly used when infertility is linked to hormone signaling issues rather than blocked sperm transport.
Are the dosing and monitoring approaches the same for both?
No. Even though the same active ingredient (hCG) is used, clinicians adjust the regimen based on whether the patient is trying to trigger ovulation (female use) or stimulate hormone production and sperm development (male use). Monitoring also differs because risks and outcomes to watch for are not the same in women versus men.
What patients typically should ask their clinician
Patients often need to confirm the exact indication (ovulation trigger vs. hormone stimulation for sperm production), the timing of injections relative to intercourse or procedures, and what monitoring they should expect (ultrasound and hormone checks in women; hormone levels and semen parameters in men).

I don’t have the underlying Prescribing Information details for Pregnyl in the provided material here, so I can’t cite the specific label language directly. If you share the country/product label you’re looking at (or paste the relevant section), I can map it precisely to male vs. female indications.
