Why does sterility result with undescended teseicles?

Undescended testicles, or cryptorchidism, can lead to sterility primarily due to the higher temperatures found within the abdominal cavity compared to the cooler environment of the scrotum, which is essential for optimal sperm production. Elevated temperatures can impair the function and development of spermatogenic cells, resulting in reduced sperm count or complete azoospermia. Additionally, the absence of testicles in the scrotum may disrupt normal hormonal signaling, further affecting fertility. Timely surgical intervention can often restore fertility potential, depending on the age of the individual and the duration of the undescended condition.
