Overview
Testicles or Testes are the male reproductive glands. The Testicles are located in the skin and membrane pouch below the Penis called the Scrotum they are suspended from the body by the spermatic cord. The membrane is able to raise (bringing the Testicles closer to the body) or lower them further from the body - this maintains the Testicles at a controlled temperature best able to produce healthy Spermatazoa. The Testicles produce the male reproductive cells Spermatazoa known more commonly assperm also Testosterone.
Details of Anatomy
The Testicles are made up, in the main, of a mass of seminiferous tubules in which sperm is developed. These tubules are lined with Sertoli cells, which protect and supply the nutrients to the developing sperm. Sertoli cells also produce and secrete the hormone 'inhibin', this hormone is involved in the regulation of the production of sperm.
Also in the Testicles are Leydig cells, located in the tissue between the seminiferous tubules, these secrete testosterone and Androsterone. These hormones stimulate masculinity particularly at puberty and the development of male sex organs, beard growth, muscle mass, and the deepening of the voice.
