Ovarian response to exogenous gonadotropins in women with elevated serum prolactin.

To determine if elevated serum prolactin hPRL inhibits ovarian steroidogenesis and contributes to the amenorrhea associated with galactorrhea syndromes, the following study was performed. Four women with amenorrhea, galactorrhea, and elevated serum hPRL levels were treated with menopausal gonadotropins (Pergonal) for the associated infertility. Urinary estrogen response was comparable to that in normal ovulatory women in each patient. Ovulation occurred in 3 of the 4 women with resultant conception and normal pregnancies. There was no evidence to support the contention that elevated hPRL interferes with ovarian function.
