Can undescended testicles be cured at 19 years old?

Surgically: Although undescended testes can be surgically corrected at any time, the longer they remain in the incorrect location, the lower the chances are that they will make adequate sperm. There is also a risk of malignancy in these testes. See your urologist to discuss your options.

Define cure: To maintain normal function the undescended testis is usually located & brought down surgically if possible by a year of age. Delays diminish the chance that it will make normal sperm. The testis must first be found if present as it can loose blood supply & disappear. If abdominal, it may not have blood vessels long enough to let it be brought down. Your urologist can provide you with more detail.

Agree with Furguson: But additionally, undescended testes should be surgically brought down because they develop cancer at a higher rate than descended testes.
