The groundwork for the production of these unique cells is laid during fetal development. Specialized cells known as germ cells migrate to the reproductive tract and settle in the gonads. During puberty, the cells start to divide, producing sperm. Over the course of a man's lifetime, he pro...

Somatic cellsSperm cellsStudent's understandingsThis paper presents further findings from a study of young people's understanding of genetics towards the end of their compulsory science education. It focuses on the ability of these students to distinguish between genes and genetic information and the ...
What are epithelial cells in sperm?Epithelial Cells:Epithelial cells primarily form a lining along passageways of the body as well as they form the layers of skin outside the body. They do this to provide a barrier that protects the tissues beneath them from invasion by harmful organisms....
There are almost as many things to know about semen as there are individual sperm inside of it. Sure, we often talk about semen in the context of the reproductive process, but not everyone having sex is doing so with the goal of pregnancy. There's a whole world of semen beyond fertili...
the cells and helps to control the speed at which they move. The energy required for the whiplike or flagellar motion with which the tail propels each sperm cell through the seminal fluid is provided by small cellular structures called mitochondria which surround the upper portion of the tail....
Spermatogenesis is the process of making sperm cells, or developing immature germ cells known as spermatogonia into mature sperm cells called spermatozoa. A sperm cell is the male reproductive cell that fertilizes the female egg in sexual reproduction. A male’s ability to reproduce depends on a ...

The ratio of 2nd to 4th digit length: a predictor of sperm numbers and concentrations of testosterone, luteinizing hormone and oestrogen. The differentiation of the urinogenital system and the appendicular skeleton in vertebrates is under the control of Hox genes. The common control of digit ......
