Prostaglandins and their effects on human placental adenyl cyclase
Abstract:
Prostaglandins increased adenyl cyclase activity in human term placental homogenates in a dose-dependent manner during 10-min incubation periods. The potency of the prostaglandins examined was demonstrated to be in the ascending order, prostaglandin F(1alpha) < A(2), F(2alpha), B(2) < A(1) < E(2) < E(1). Although no specific trophic or regulating factors for placental function have been described as yet, it is possible that prostaglandins which are synthesized in decidual tissue could play such a physiological role.

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
