Abstract

Mammalian sperm have angiotensin II (AII) receptors, seminal plasma contains AII and AII stimulates sperm motility/capacitation/fertilisation in vitro. These data suggest an important role for AII in male fertility in vivo, but raise key questions about AIIs source and availability in relation to sperm function. We will study, in normal and transgenic male rodents: 1) formation of AII in the reproductive tract (particularly tissue sources of seminal plasma AII) and its hormonal regulation; 2) correlation of AII availability with key events in sperm function (e.g. capacitation, acrosome reaction); and 3) mechanisms of action following AII binding to sperm. Findings will have implications for new approaches to fertility regulation. (Joint with grant 29/S13504)
