Abstract

Apoptosis is a genetically controlled form of cell suicide. Due to the cyclic nature of the female reproductive system, the ovary, the endometrium and the mammary gland sustain continuous cycles of cell growth and apoptosis in response to hormonal changes. Apoptotic cell death plays multiple roles during embryonic and organ development. It is involved in sculpturing tissues and serves to delete structures that are no longer required. It is clear that apoptosis plays an active and important role in ovarian physiological functions. Apoptosis plays a major role during folliculogenesis and dominant follicle selection and also plays part in corpus luteum regression. In addition, it has been shown that programmed cell death plays important roles in the mammary gland development and ductal morphogenesis. During puberty, lumen formation is associated with the selective apoptosis of centrally located cells. In turn, postlactational involution of the mammary gland is characterized by the secretory epithelial cells undergoing programmed cell death. Apoptosis has also been associated with physiological, as well as pathological, endometrial processes such as cancer and endometriosis. The delicate balance between apoptosis and cell proliferation is essential in controlling the cyclical growth of the reproductive tissues and plays an important role in the prevention of neoplastic transformation.
