Spermatogenesis is the process by which haploid spermatozoa develop from germ cells in the seminiferous tubules of the testis. This process starts with the mitotic division of the stem cells located close to the basement membrane of the tubules. These cells are called spermatogonial stem cells. The mitotic division of these produces two types of cells. Type A cells replenish the stem cells, and type B … WebC. Spermatogenesis in males results in four functional sperm while oogenesis in females results in only one egg and three structures that contain genetic information that is lost when they disintegrate.

WebThe World Health Organization (WHO) defines infertility as the inability of a sexually active, non-contracepting couple to achieve spontaneous pregnancy within one year.

WebKeeping the sperm cool prevents damage from heat. Sperm are very sensitive to temperatures above 35 degrees Celsius (95 degrees F). At these temperatures, they begin to die off rapidly. Even though the body is trying to protect the sperm by keeping them warm, they are still at risk for damage if the temperature rises too high.
