Human Reproductive System

Describes male & female systems in fertile & infertile conditions, causes of dysfunction.

The Endocrinology of Infertility
The female and male reproductive systems share many similarities. Both are modulated by the effects of various hormones. Some of these include gonadotropin-releasing hormone, follicle-stimulating hormone, and luteinizing hormone. Likewise, endocrine abnormalities in both females and males can result in reproductive system dysfunction. Among females, progesterone deficiency may cause infertility. In males, sterility can result from insufficient gonadotropins.

Human reproduction requires the complex interplay of multiple anatomic and physiologic systems. Various interactions between the central nervous system and the gonads determine the levels of various hormones. These endocrine signals provide a mechanism by which different reproductive system processes are…
