Ovary - Anatomy & Physiology

BACK TO REPRODUCTIVE SYSTEM

Introduction

The ovary is the female Gonad homologous to the male Testes. It is ususally a paired organ in domestic species but in the bird only the Left Ovary is present. The structures in ovary are undergoing constant changes throughout the oestrus cycle from the Follicles containing Oocytes, to the formation of Corpus Haemorrhagicum, Corpus Luteum, and finally Corpus Albicans.

Function

• It has two main functions:
  • Producing gametes (Gametogenesis)
  • Producing the reproductive hormones Oestrogens and Progesterone, its endocrine function.
