Q53: Undescended testicle

The group of conditions outlined under the title 'Undescended testicle' refer to a common male genital issue where one or both of the testes have not moved down into the scrotum before birth. This condition can be classified as unilateral if only one testicle is affected and bilateral if both testicles are involved. Generally, there is no clear cause for this condition but it can possibly be linked to genetics, maternal health, or environmental factors. Symptoms are typically not painful but the testicle might be hard to feel or missing from the scrotum. It's important to know that even when the testicle descends on its own after birth, this should still be checked by a healthcare professional as it might increase the risk of complications later in life, such as infertility or testicular cancer. This condition primarily affects a boy's reproductive system and typically becomes apparent at birth.
