Sperm require a temperature lower than body temperature in order to develop properly. It's too warm inside the body.
The hormone responsible for the descent of the testes into the scrotum during development is called testosterone. It is produced by the testes and plays a crucial role in the development of male reproductive organs.
The primary reason the scrotal sac descends is to regulate the temperature of the testes for optimal sperm production. The lower temperature outside the body allows the testes to function properly and produce viable sperm.
temperature decreases
Approximately 3-4% of full-term male infants are born with undescended testes. In most cases, the testes will descend on their own within the first few months of life, but if they do not, medical intervention may be necessary to prevent complications.
The testes usually descend into the scrotum during the third trimester of pregnancy. The descent is typically completed by the time a male baby is born.
cryptorchidism
Cryptoorchidism
In order to fully descend, the testes must pass through the inguinal canal, which is a passage in the abdominal wall. This process occurs during fetal development and is essential for the testes to properly position in the scrotum. Failure of the testes to descend completely can lead to complications like infertility or increased risk of testicular cancer.
Cryptochidism- failure of testes to descend from the abdomen (develop there) to scrotum. 1. surgery or hormones to correct 2. sterility is not fixed 3. testes atrophy, potential site of cancer
cryptorchidism
Undescended Testicle/s is the condition you refer to. It's when at birth one or both of the testes have not dropped into position in the scrotum. It happens in roughly one in 25 boys but usually it's nothing to worry about as the testes will normally move into position on there own.
Once it is determined that the testes will not naturally descend, surgery becomes necessary. The procedure is called an orchiopexy and is relatively simple once the testes are located.
Cryptorchidism is when one or both of the testicles fails to descend into the scrotum. It is also called undescended testicle(s). Uncorrected cryptorchidism can increase the risk of male infertility and testicular cancer.
If the testes don't descend (drop) after birth, then the male can become sterile (infertile), and the risk of testicular cancer increases.
cause testes need a a colder environment to function,if it was in a warmer place of the boddy their function isn't guaranteed
The hormone responsible for the descent of the testes into the scrotum during development is called testosterone. It is produced by the testes and plays a crucial role in the development of male reproductive organs.
If the testes are not maintained at a temperature about 2 °C lower than body temperature the process of spermatogenesis will not take place, so that is why it is important for the testes to descend into the scrotum during maturation.
