Man’s internal sexual organs | Zanzu

The testes are the primary male sexual organs in that they make sperm and produce testosterone. The sperm is the male sex cell, or gamete, and each testicle produces more than 4 million new sperm per hour [source: Angier ]. Testosterone is the hormone that causes male secondary sex characteristics such as facial and pubic hair, thickened vocal cords and developed muscles. The testes are housed outside of the main part of the male's body, in a sac called the scrotum. This location is important because in order for the sperm to develop properly, they must be kept at a temperature about two degrees cooler than normal body temperature. It takes sperm about 4 to 6 weeks to mature, which they do as they travel from each testis to a coiled tube on the outer surface of each testis called the epididymis. Sperm, which are often compared to tadpoles in appearance, use their tails to travel, while the head contains the genetic material.

While this sounds like something out of a sci-fi movie, unfortunately, this fear does have some truth to it. While it's not really possible for penises to gradually shrink inch by inch, it's true that due to age and lifestyle choices, your penis could potentially lose the ability to maintain a consistent level of tumescence. So what is tumescence?

Sex reassignment surgery for female-to-male transgender people includes a variety of surgical procedures that alter anatomical traits to provide physical traits more comfortable to the trans man's male identity and functioning. Non-binary people assigned female at birth may also have these surgeries. Often used to refer to phalloplasty , metoidoplasty , or vaginectomy , sex reassignment surgery can also more broadly refer to many procedures an individual may have, such as male chest reconstruction , hysterectomy , or oophorectomy. Sex reassignment surgery is usually preceded by beginning hormone treatment with testosterone. Also called "top surgery", male chest reconstruction is any of a variety of surgeries to remove breast tissue, and provide shaping of a male contoured chest.
