Pregnancy Rates after Testicular Torsion

To our knowledge the effect of testicular torsion on the pregnancy rate is unknown. In this study we focused on the pregnancy rate, which is the ultimate index of fertility status.

We reviewed the records of 273 patients who presented to our emergency room with testicular torsion between 1994 and 2014. Study inclusion criteria included being in a relationship with the intent to conceive for at least 1 year, age greater than 25 years and a normal contralateral testis. Patients with primary infertility, those who were unwilling to participate or unreachable and those with a history of undescended testis and/or varicocele were excluded from analysis. Patients were contacted by telephone and interviewed according to a standardized questionnaire. Pregnancy rates in the orchiopexy and orchiectomy groups were compared to each other and to the accepted pregnancy rate in the literature.

A total of 63 patients met study inclusion criteria, including 41 and 22 in the orchiopexy and orchiectomy groups, respectively. The pregnancy rate in the orchiopexy and orchiectomy groups was 90.2% and 90.9%, respectively (p = 1.0). The accepted pregnancy rate in the general population is 82% to 92%. Mean ± SD time to pregnancy in the orchiopexy and orchiectomy groups was 6.6 ± 5.50 and 7.2 ± 5.4 months, respectively (p = 0.27).

Several studies suggest decreased fertility potential in patients with a history of testicular torsion. However, in the current study in couples in which the male had a history of testicular torsion the pregnancy rate and the interval to pregnancy were within the accepted range of the general population.
