Detailed explanation-1: -The testis resides in the abdomen near the internal ring until descent through the inguinal canal occurs at the beginning of the third trimester. An important player in testicular descent is the gubernaculum testis.
Detailed explanation-2: -Testicles form in the abdomen during fetal development. During the last couple of months of normal fetal development, the testicles gradually descend from the abdomen through a tube-like passageway in the groin (inguinal canal) into the scrotum. With an undescended testicle, that process stops or is delayed.
Detailed explanation-3: -Order Chiroptera, which includes bats, order Proboscidea, which includes elephants and Cetacea, which includes marine mammals, like a dolphin, whale etc. all of them have intra-abdominal testes because their internal body temperature is optimum for sperm production.
Detailed explanation-4: -The testicles make sperm. To do this, the temperature of the testicles needs to be cooler than the inside of the body. This is why the scrotum is located outside of the body.
