Which hormone injections are sometimes used to treat undescended testicles?

The use of B-HCG, or beta-human chorionic gonadotropin, is recognized in some cases for treating undescended testicles, a condition known as cryptorchidism. B-HCG functions similarly to luteinizing hormone (LH), stimulating the Leydig cells in the testes to produce testosterone. This testosterone can assist in the descent of the testicles into the scrotum, particularly when surgery may not be immediately indicated or as a preparatory step for surgical intervention. By promoting the natural processes involved in testicular descent, B-HCG can help in managing this condition effectively, making it a relevant treatment option.

Other hormones mentioned in the options do not have a similar role in this context. Estrogen and progesterone, known primarily for their roles in the female reproductive system, do not play a direct therapeutic function in inducing testicular descent. Oxytocin, while important in various physiological processes like childbirth and lactation, does not have any established role in the treatment of undescended testicles. Thus, B-HCG stands out as the hormone injection sometimes utilized for this specific condition.
