Abstract
Thirteen pregnant women were given synthetic luteinizing hormone-releasing hormone (LH-RH) by a single intravenous injection. Serum concentrations of follicle-stimulating hormone (FSH) were measured by radioimmunoassay. A significant rise in FSH was found after LH-RH administration in 10 of the 13 patients; however the response was very variable in each case. The maximum increase in the serum levels of FSH above the base line remained constant with the advancement of pregnancy. The present study confirms that the pituitary gland responds to LH-RH administration with the secretion of FSH despite the high levels of sex steroid and chorionic gonadotropin during pregnancy.
