Paternity was compromised in men with a history of unilateral cryptorchidism, with infertility occurring twice as often compared to controls. Age at surgery or lifestyle did not impact paternity outcomes.

Area of Science:

  • Urology
  • Reproductive Medicine
  • Pediatric Surgery

Background:

  • Cryptorchidism, specifically unilateral cryptorchidism, is a condition affecting male reproductive health.
  • Surgical correction (orchiopexy) is performed to address undescended testes.

Purpose of the Study:

  • To investigate the long-term impact of formerly unilateral cryptorchidism on paternity.
  • To compare paternity rates between men who underwent orchiopexy and a control group.

Main Methods:

  • Retrospective review of medical records for formerly unilateral cryptorchid men treated between 1955-1971.
  • Survey questionnaires administered to both cryptorchid and control groups to assess paternity outcomes.

Main Results:

Related Experiment Videos

  • Men with a history of unilateral cryptorchidism had significantly higher rates of infertility (10.5%) compared to controls (5.4%).
  • No differences were observed in time to conception between groups.
  • Paternity was associated with female infertility factors and the presence of varicoceles in both groups.

    • Conclusions:

    • Unilateral cryptorchidism compromises paternity, leading to approximately double the rate of infertility compared to the general population.
    • Subfertility, defined by longer conception times, was not evident in the fertile subgroup.
    • The age of orchiopexy did not correlate with paternity outcomes.
