WebThese cycles occur concurrently and are coordinated over a 22–32 day cycle, with an average length of 28 days. The first half of the ovarian cycle is the follicular phase shown in Figure 2. Slowly rising levels of FSH and LH cause the growth of follicles on the surface of the ovary. This process prepares the egg for ovulation. WebSpermatogenesis refers to the formation of sperm, which is the male reproductive cell. Unlike the female reproductive cell, sperm are created continuously throughout the lifetime of the male after he reaches puberty. In fact, more than 100 million sperm cells can be produced in a single day!
