    Summary
    This summary is machine-generated.

    Undescended testicles (cryptorchidism) are linked to male sterility. Early surgical correction before age 4 improves testicular volume and fertility outcomes in affected men.

    Area of Science:

    • Reproductive Endocrinology
    • Andrology
    • Pediatric Surgery

    Context:

    • Cryptorchidism, the failure of one or both testicles to descend into the scrotum, is a known risk factor for male infertility.
    • This study examines the long-term reproductive outcomes in a cohort of sterile men with a history of cryptorchidism.

    Purpose:

    • To investigate the association between antecedent cryptorchidism and male sterility.
    • To evaluate the impact of surgical correction timing and hormonal treatments on fertility in these patients.

    Summary:

    • Out of 1190 sterile men, 88 had a history of cryptorchidism (55 bilateral, 33 unilateral).
    • Azoospermia was prevalent in bilateral cases (16/20). Sperm analysis revealed oligospermia, teratospermia, or altered motility in most patients.
    • Hormonal imbalances, including elevated FSH and hypotestosteronemia, were observed in one-third of subjects, particularly those with bilateral cryptorchidism.

  • Surgical correction before age 4 correlated with better testicular volume. Hormonal therapy and varicocele repair improved fertility, leading to 10 pregnancies.

    • Impact:

    • Highlights the critical importance of early surgical intervention for cryptorchidism (before age 4) to maximize fertility potential.
    • Demonstrates that hormonal treatments and varicocele surgery can improve reproductive outcomes in men with a history of undescended testicles.
    • Provides evidence supporting timely management of cryptorchidism to mitigate long-term consequences on male fertility.
