The testicles, known medically as testes (singular testis), are the male generative glands in animals. In mammals, the testicles are paired bodies that are contained within a pouch termed the scrotum.

Like the ovary testicles have two distinct functions :

Under a tough fibrous shell - the tunica albuginea the testis contains very fine coiled tubes called the seminiferous tubules. The tubes are lined with a layer of cells that from puberty until old-age is producing sperms. The seminiferous tubules lead to epidydimis, where newly created sperms mature, and then into vas deferens (also called the ductus deferens) that opens into the urethra. During sexual intercourse, the sperm then moves through the ejaculatory duct and into the prostatic urethra, where the prostate through muscular contractions ejaculates the sperm, mixed with other fluids, out through the penis.

Between the seminiferous tubules are special cells called interstitial cells (Leydig cells) where testosterone and other androgens are formed.

The testicles are well-known to be very sensitive to impact and injury. This has been a rich source of humor for jokes and comedic routines.

The most important diseases of testicles are :

If a testicle is medically removed (orchidectomy) or destroyed through disease or injury, testicular prostheses are available to mimic the appearance and feel of the missing testicle.

Both components of the testicle, sperm-forming and endocrine, are under control of gonadotropic hormones - lutenizing hormone (LH) and follicle-stimulating hormone (FSH), that are produced by the anterior pituitary.
