Clomifene citrate

Clomifene citrate (Serophene) is a selective estrogen receptor modulator. Clomifene citrate (Serophene) increases production of gonadotropins by inhibiting negative feedback on the hypothalamus. Clomifene citrate (Serophene) is used mainly for ovarian stimulation in female infertility due to anovulation (e.g., infertility in polycystic ovary syndrome). Therapeutically, clomifene citrate (Serophene) is given early in the menstrual cycle. Clomifene citrate (Serophene) is typically prescribed beginning on day 1, 3 or 5 and continuing for 5 days. By that time, FSH level is rising steadily, causing development of a few follicles. Follicles in turn produce the estrogen, which circulates in serum. Clomifene acts by inhibiting the action of estrogen on the pituitary.
