Ovarian derived prorenin-angiotensin cascade in human reproduction

Abstract

Objective: To review the available literature concerning the renin-angiotensin system of the human and animal ovary and to outline the clinical relevance of this system.

Design: The location, function, and regulation of the components of the ovarian prorenin cascade are described. The possible functions of this system as well as its association with common gynecologic problems are also given.

Conclusions: The ovary contains a complete cascade whose end product is the formation of angiotensin II. Angiotensin II may have a role in steroid synthesis, oocyte maturation, ovulation, and corpus luteum formation. Further, aberrations in this system are associated with ovarian tumors, ectopic pregnancy, pre-eclampsia, and ovarian hyperstimulation syndrome.
