[Impact of unilateral cryptorchidism on the levels of serum anti-müllerian hormone and inhibin B].

Objective: To investigate the influence of unilateral cryptorchidism on the levels of serum anti-müllerian hormone (AMH) and inhibin B in children.
Methods: We enrolled 65 patients with unilateral cryptorchidism and 45 healthy children in this study. We measured the length and circumference of the penis, the testis volume in the cryptorchidism side, and the levels of serum AMH and inhibin B at the age of 6 and 12 months, respectively.
Results: Compared with the healthy controls, the patients with unilateral cryptorchidism showed significant decreases at 12 months in serum AMH (［108.06±12.40］ vs ［103.26±17.57］ ng/ml, P<0.05) and inhibin B (［77.43±5.66］ vs ［70.21±5.69］ pg/ml, P<0.05). No statistically significant differences were found in the length and circumference of the penis and the testis volume in the cryptorchidism side at 6 and 12 months (P>0.05), or in the levels of serum AMH and inhibin B at 6 months (P>0.05).
Conclusions: Unilateral cryptorchidism affects the gonadal function of the patient, and orchiopexy should be timely performed in order to reduce its impact.
