Reproduction
- The seminiferous tubules within the testes are the site of sperm production.
- Spermatogenesis is the process of sperm production. One primary spermatocyte yields four spermatozoa.
- Oogenesis is discontinuous, with development arrested during prophase I and again in meiosis II. One primary oocyte yields one ovum plus polar bodies.
- The first half of the menstrual cycle is the follicular phase. Under the influence of follicle stimulating hormone (FSH), a primary oocyte matures within the follicle.
- The developing follicles produce estrogen, which stimulate the proliferation of the endometrium.
- An LH surge precedes ovulation. At ovulation the follicle ruptures, releasing an ovum.
- The second half of the cycle is the luteal phase. The ruptured follicle develops into a corpus luteum under the influence of luteinizing hormone (LH). The corpus luteum produces progesterone.
- Progesterone maintains the endometrium and stimulates the development of glands within the endometrium. In the absence of pregnancy, the corpus luteum atrophies and the uterine lining is shed.
- In males, FSH stimulates Sertoli cells, which play a role in sperm development. LH stimulates Leydig cells to produce testosterone.
