Testosterone and sperm production

Testosterone the principle male sex hormone is needed for normal production of sperm cells.  Testosterone is secreted in testicles. A small amount of this hormone is also secreted by adrenal glands.

The developing sperm cells are supported by Sertoli cells. Sertoli cells are situated within seminiferous tubules of testes. These cells provide nourishment to developing sperms and support them. 

The process of spermatogenesis (the process of production of sperms) is extremely sensitive to fluctuations in surrounding environment. The process very quickly varies to fluctuation of hormone concentration and temperature. High concentration of testosterone is required in surrounding area where sperms develop. The supportive sertoli cells maintain the environment needed for development of sperms. These cells produce a binding protein which concentrates testosterone in the surrounding environment where spermatogenesis takes place.

Low levels of testosterone slow down the process of spermatogenesis or sperm production. Hence all measures have to be taken to maintain the normal level of testosterone to increase sperm count and sperm motility.

Testosterone And Male Fertility - How Is Sperm Related To Testosterone?

Everybody has probably already heard of testosterone.  The word testosterone often conjures up images of big muscle bound bodybuilders, and other manly-man stuff.  In fact, testosterone is almost single-handedly responsible for men's masculine characteristics.

Though testosterone is found in both men and women, the concentration of this steroidal hormone is typically about eight to ten times higher in men.  It is produced in the testis (for men), the ovaries (for women), and in much smaller amounts in the adrenal gland.  For the purpose of this article, we will be focusing on the effects of testosterone on men as opposed to women.

Beginning at about puberty, young men's testis start to increase their testosterone production.  The effects can be seen as changing (lowering) voice, pubic hair (facial and body), enhanced muscle growth, and most importantly the production of sperm.  Testosterone production usually remains strong until around age 40, when it gradually starts to decline.

While the testosterone hormone is not directly responsible for manufacturing sperm cells, it is still a part of the process.  A man's testis are primarily responsible for two things: sperm cell production, and testosterone production.  When testosterone levels drop in the body, a sequence of triggers tells the testis to produce more testosterone and more sperm.

Not only is testosterone a major player in sperm production, it is very active in the sexual activity of men.  Men struggling with low testosterone levels will suffer decreased libido and sex drive.  Impotence or "ED" is often a side effect of low testosterone.

Boosting testosterone levels in men is achievable, but should only be done so with the advice of a medical professional.  If you suspect you may be suffering from decreased testosterone levels, you should visit your local health professional.
