Is pregnyl for fertility?

Is Pregnyl used for fertility treatments?

Pregnyl contains human chorionic gonadotropin (hCG) and is prescribed to trigger final egg maturation and ovulation in women undergoing assisted reproduction. It is also given to men with hypogonadotropic hypogonadism to stimulate testosterone production and sperm formation.

How is Pregnyl administered during IVF cycles?

Clinics typically inject 5,000–10,000 IU of Pregnyl 34–36 hours before egg retrieval. The timing is chosen so the eggs reach metaphase II stage without premature ovulation. Patients usually receive the injection at home after nurse instruction.

Why do doctors choose Pregnyl over other hCG products?

Pregnyl is a urinary-derived product that has been available for decades, so many reproductive endocrinologists are familiar with its dosing and safety profile. Some centers still prefer it over recombinant hCG options because cost and insurance coverage can favor the urinary version.

What happens if the Pregnyl trigger shot is missed or mistimed?

Missing the window or injecting too early can result in immature eggs at retrieval or early luteinization. Clinics usually reschedule the cycle or switch to an alternative trigger such as leuprolide acetate when timing cannot be corrected.

Can men use Pregnyl to improve fertility?

Yes. Men with low testosterone or low sperm counts caused by pituitary issues may receive 1,000–2,000 IU two to three times per week. Blood tests and semen analyses are monitored every 4–6 weeks to adjust the dose.

When do Pregnyl patents expire?

The original patents for urinary hCG products like Pregnyl have long expired. Generic and biosimilar hCG products are already marketed in many countries.
