This pregnyl is human chronic gonadotropin,a hormone that supports the normal development of an egg in a woman ovary,and stimulates the realese of the egg during ovulation.HCG is used to cause ovulation and to treat infertility in women,and to increase sperm count in men
Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta, is composed of an alpha and a beta subunit. The alpha sub-unit is essentially identical to the alpha subunits of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha subunit of human thyroid-stimulating hormone (TSH). The beta subunits of these hormones differ in amino acid sequence.

This medication is a hormone used in boys (before puberty) to cause the normal dropping of the testicles into the scrotum. It is also used in certain boys to help with normal sexual development. It works by causing the testes to release male sex hormones (e.g., testosterone).This medication is also used in women to treat fertility problems. It is given after finishing another medication (menotropins) to cause the release of an egg (ovulation). It should not be used in women whose ovaries no longer make eggs properly (primary ovarian failure).This medication has not been shown to be effective for weight loss and should not be used for this purpose due to risk of serious side effects.
