The controversy regarding the need for hormonal treatment in boys with unilateral cryptorchidism goes on: a review of the literature

Hormonal treatment for unilateral undescended testes continues to be recommended in some countries. We reviewed the literature in favor and against this recommendation. Since the paternity rate of men with a history of unilateral undescended testes only treated with surgery is normal, the effectiveness of hormonal treatment to produce testicular descent is low, the cost is considerable, and there are potential adverse effects, hormonal treatment for boys with unilateral undescended testes should no longer be recommended.
