Physiology of Aging

Physiology of aging is two different terms with a common meaning. That is, the aging processes.

Aging on the other hand simply refers to accumulation of age. Thus, in a sense, physiology of aging refers to the natural processes of the human body as it accumulates more years of existence. This…

Formation of Sperm

The formation of sperm in humans, also called spermatogenesis is a process that spans 65-75 days and permits the production of approximately 300 million mature sperm per day in a normal male individual (Tortora and Derrickson, 2006, p. 1062). Sperm develop from the specialization of stem cells located close to the basement membrane of seminiferous tubules in the testis. These stem cells are called spermatogonia which form from the yolk sac or the extraembryonic membrane and migrate into the testis…
