In vitro pituitary responsiveness to gonadotropin-releasing hormone (LH-RH) in intact and castrated male and female rats.


The in vitro response of pituitaries isolated from both normal and 18-21 day post-castration male and female intact rats to incremental doses of synthetic gonadotropin-releasing hormone (LH-RH) has been investigated. Intact male pituitaries released luteinizing hormone (LH) maximally at the smallest dose of LH-RH (0.1 ng/ml) whereas intact female… (More)
