In this lesson our instructor talks about reproduction. First she discusses asexual and sexual reproduction. Then she talks about the male and female reproductive system. After, she discusses spermatogenesis, oogenesis, the menstrual cycle and a summary of the ovarian and uterine cycles. Lastly, she lectures on oxytocin, prolactin, regulation of the male reproductive system, and fertilization. Four complete example videos round up this lesson.

within the endometrium. In the absence of pregnancy, the corpus

In males, FSH
stimulates Sertoli cells, which play a role in sperm development. LH
stimulates Leydig cells to produce testosterone.
