Background/purpose: Although fertility is decreased after cryptorchidism, the importance of risk factors, including parenchymal testicular suture, is unknown. The aim of this study was to examine the relationship between parenchymal testicular suture and failure to conceive a child for 1 year or longer among formerly cryptorchid men.
Methods: Men who underwent orchidopexy between 1955 and 1972 at the Children's Hospital of Pittsburgh (n = 619) were surveyed by questionnaire and their medical records reviewed. Only the men who attempted to conceive a child (n = 387) are included.
Results: Logistic regression analysis determined significant risk factors for infertility. Testicular suture was strongly related to infertility (RR, 7.56; 95% CI, 1.66, 34.39) as were bilateral cryptorchidism (RR, 5.51; 95% CI, 1.58, 19.24), varicocele (RR, 4.72; 95% CI, 1.42, 15.75), hormone treatment before surgery (RR, 3.69; 95% CI, 1.22, 11.11), and partner conception problem (RR, 3.32; 95% CI, 1.11, 9.90).
Conclusions: Testicular suture was a potent independent determinant of infertility among formerly cryptorchid men who have orchidopexy. Bilateral cryptorchidism, hormone treatment, varicocele, and partner conception problems also were associated with increased infertility.
