Undescended Testis

Undescended testis, also known as cryptorchidism, is a condition in which one or both testicles fail to move into the scrotum before birth. Normally, the testicles develop inside the abdomen during pregnancy and gradually descend into the scrotal sac before delivery. This condition is more common in premature babies and may affect one or both sides. In many infants, the testicle descends naturally within the first few months of life.

The main sign of an undescended testis is the absence of a testicle in the scrotum. Although the condition may not cause pain, untreated cases can increase the risk of infertility, testicular cancer, hernia, and testicular torsion later in life. Early diagnosis and treatment are important to support healthy reproductive development and reduce long-term complications.

Doctors diagnose the condition through physical examination and sometimes imaging tests such as an ultrasound. If the testicle does not descend naturally by six months of age, surgery called orchiopexy is usually recommended to place the testicle into the scrotum. Timely treatment improves fertility potential, reduces cancer risk, and helps maintain normal hormonal and testicular function.
