Gonasi Set (Human Chorionic Gonadotropin)

It is prescribed for ovulation induction in assisted reproductive techniques, luteal‑phase support, induction of spermatogenesis in hypogonadotropic hypogonadism, treatment of cryptorchidism, and as adjunct therapy in certain cases of male testosterone deficiency.

Gonasi Set is given by a healthcare professional as an intramuscular or subcutaneous injection, following the dosing schedule determined by the treating physician.

Gonasi Set is not intended for use in women who are already pregnant. Pregnancy status should be confirmed before each administration.

Common side effects include injection‑site pain or bruising, headache, fatigue, mild nausea or abdominal discomfort, and mild ovarian swelling in women.

Serious reactions may include ovarian hyperstimulation syndrome, severe allergic reactions such as anaphylaxis, thromboembolic events, acute abdominal pain suggesting ovarian torsion, and unexpectedly high testosterone levels in men.

Precautions include confirming the patient is not pregnant, assessing risk of ovarian hyperstimulation, reviewing thyroid function, checking for hypersensitivity to hCG, evaluating cardiovascular or clotting disorders, and planning regular monitoring of hormone levels.

Monitoring typically includes serial ultrasound of the ovaries in women, serum estradiol and progesterone levels, thyroid function tests, and testosterone levels in men, as well as observation for signs of OHSS or allergic reactions.
