The testicles are the male gonads — the primary male reproductive organs. They have two, very important functions that are very important to the male reproductive system: they produce gametes, or sperm, and they secrete hormones, primarily testosterone. Testicles, or testes, are oval-shaped organs located in the scrotum, just behind the penis and right in front of the anus on male humans. Each testis weighs 0.
Male Reproductive System - Structure, Function, Hormones, Sperm, Testis
The two testes , or testicles, which usually complete their descent into the scrotum from their point of origin on the back wall of the abdomen in the seventh month after conception , are suspended in the scrotum by the spermatic cords. Each testis is 4 to 5 cm about 1. This sac is lined internally by the tunica vasculosa, containing a network of blood vessels, and is covered by the tunica vaginalis, which is a continuation of the membrane that lines the abdomen and pelvis. The tunica albuginea has extensions into each testis that act as partial partitions to divide the testis into approximately compartments, or lobules. Each lobule contains one or more convoluted tubules , or narrow tubes, where sperm are formed.
Carole Wegner is a Ph. Sperm are produced in the male testicle testis. The testis is filled with tiny coiled tubes seminiferous tubules through which sperm move as they are produced.
The testes singular: testis , commonly known as the testicles, are a pair of ovoid glandular organs that are central to the function of the male reproductive system. The testes are responsible for the production of sperm cells and the male sex hormone testosterone. Located in the hollow sac of the scrotum, each testis is about 1.
