Male Gonads








www.becomehealthynow.com/popupstestes_section.htm

Male gonads or testes, are one of a pair of glands that produce the male reproductive cells, or sperm. In fetal life the testes develop in the abdomen, then go down into an external sac, the scrotum. A testis is composed of coiled seminiferous tubules whose linings contain cells that develop into sperm. These tubules combine into a larger tube called the epididymis that leads out of the testis into the vas deferens. The outer part of each testes consists of a thick, white connective tissue capsule. Extensions of the capsule project into the interior of the testes and divide each testes into about 250 cone-shaped lobules. The lobules contain seminiferous tubules, in which sperm cells develop. Interstitial cells is a connective tissue surrounding the seminiferous tubules contains clusters of endrocrine cells and it is also known as cells of Leydig which secrete testosterone. Sometimes the testes do not go down normally before or shortly after birth and remain in the abdomen. Testes are components of the reproductive system (being gonads).



The respective functions of the testes are:
producing
sperm (which the spermatozoa)
producing male
sex hormones or also known as testosterone
