The primary symptom of undescended testis (cryptorchidism) is the absence of one or both testicles in the scrotum at birth. The testicle may be felt in the inguinal canal, lower abdomen, or other parts along the descent path, but it fails to descend into the scrotum. In some cases, the testicle may be palpable in the groin area, causing swelling or discomfort. While the condition is often discovered during routine physical exams, parents may notice that one or both testicles are missing or not properly positioned. In cases where the testicle is not easily felt, a healthcare provider may use ultrasound or laparoscopy to locate it. If the testicle is in an abnormal position, it may lead to pain or tenderness during physical activities, especially in the groin or lower abdomen. Although fertility issues are not immediately apparent, an undescended testis can affect testicular function over time, potentially leading to infertility if untreated. Additionally, this condition increases the risk of complications like testicular cancer, inguinal hernia, or testicular torsion, which is a painful twisting of the testicle that can result in loss of function. Early diagnosis and treatment, such as surgery (orchidopexy), are critical to preventing long-term problems.
