The testes are composed of numerous seminiferous tubules, where spermatogenesis takes place. These tubules are lined with a specialized epithelium consisting of Sertoli cells and developing germ cells. The interstitial cells of Leydig, located between the tubules, produce testosterone.
The ovaries consist of an outer cortex and an inner medulla. The cortex contains follicles at various stages of development, each housing an oocyte. The medulla is composed of connective tissue, blood vessels, and nerves. Follicular development is regulated by hormonal cues and involves the maturation of oocytes and secretion of estrogen.
