Pregnyl is an injectable, highly purified preparation of human chorionic gonadotropin obtained from the urine of pregnant women.
Pregnyl is used in the treatment of prepubertal cryptorchidism not due to anatomical obstruction. Pregnyl is also used in selected cases of hypogonadotropic hypogonadism in males as well as for induction of ovulation and pregnancy in infertile women.
Human Chorionic Gonadotropin, HCG, is also widely used in athletics today. HCG is not a natural male hormone but mimics the natural hormone LH (Luetinising Hormone) almost identically. LH stimulates the production of testosterone by the testis in males. Thus HCG sends the same message which results in increased testosterone production by the testis due to the effect of HCG on the leydig cells of the testis. Athletes use HCG to increase the body's own natural production of testosterone which is often depressed by long term steroid use.
Human chorionic gonadotropin, HCG, is a polypeptide hormone produced by the human placenta. Pregnyl is a highly purified pyrogen-free preparation obtained from the urine of pregnant females.
Pregnyl, gonadotropin, mimics the action of the pituitary hormone luteinising hormone (LH) which controls the release of eggs from the ovary in women, and controls production of testosterone in men. Pregnyl is used to stimulate egg release in some infertile women after follicle development has been stimulated with follicle stimulating hormone. In men it is used in the management of delayed puberty, undescended testes and oligospermia (low sperm count).
Athletes use HCG to increase the body's own natural production of testosterone which is often depressed by long term steroid use.
