Undescended testicles affect 1% of males and are 10% bilateral. The cause is unknown, with a small percentage associated with developmental abnormalities or chromosomal aberrations. [citation needed] Early orchiopexy reduces the risks for cancer and sterility in males with cryptorchidism, or undescended testes. [citation needed]
Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Ancient Greek κρυπτός (kryptos) ' hidden ' and ὄρχις (orchis) ' testicle '. It is the most common birth defect of the male genital tract. [1]
Undescended testicles. Also known as cryptorchidism, undescended testicles occur when one or both testicles fail to fully migrate into the scrotum during development. ... This treatment uses ...
As the testicles are involved in testosterone and sperm production, the signs and symptoms of testicular atrophy overlap with those related to infertility or low testosterone levels. [1] In a prepubescent person with testicular atrophy, there may be underdevelopment of secondary sex characteristics (e.g. lack of penis growth). [ 2 ]
If the pre-treatment testes are very small and there has been a history of undescended testes it might take longer to achieve sperm production. In these cases, assisted reproductive technology , such as sperm retrieval using testicular sperm extraction (TESE) and/or intracytoplasmic sperm injection (ICSI), might be required.
For example, a study shows that undescended testicles affects approximately 4.8 percent of all Malaysian male newborns. [28] During normal development, testes form in the retroperitoneum, the back part of the abdomen, and subsequently descend through the inguinal canal into the scrotum. Diagnosing undescended testicles involves a physical ...

This process is triggered by androgens produced by the testicles. The bodies of unaffected XY individuals masculinize by, among other things, enlarging the genital tubercle into a penis, which in females becomes the clitoris, while what in females becomes the labia fuses to become the scrotum of males (where the testicles will later descend).
