Interaction of thyrotrophin releasing hormone with inhibin in male rats.
Inhibin administered to adult male rats delayed the in-vivo pituitary responsiveness to thyrotrophin releasing hormone (TRH) as observed in terms of prolactin release in the serum. It also decreased the sensitivity of the pituitary gland to TRH, in terms of TSH release. However, inhibin alone did not alter the serum levels of prolactin and TSH, although it significantly suppressed serum FSH levels. In addition, the inhibin effect on FSH release was blocked by TRH.
