In brief
Retrospective study of 153 men who underwent orchiopexy found no significant difference in paternity rates between smokers and nonsmokers, regardless of whether cryptorchidism was unilateral or bilateral. Results suggest tobacco consumption may not impact fertility outcomes in men with surgically corrected undescended testes.

Abstract
Objective
To determine the effect of tobacco consumption on paternity rates in men with a history of cryptorchidism. To compare the paternity rates between formerly unilateral, bilateral cryptorchid smokers, and nonsmokers.
Methods
A retrospective cohort study of 153 men who had undergone orchiopexy between 1961 and 1985 at the Miguel Servet University Hospital (116 unilateral and 37 bilateral) and a control group of 100 men were evaluated by review of medical records and a questionnaire.
Results
A total of 197 men filled the questionnaire (76.7%). There was no difference in paternity rates between smokers compared to nonsmokers (P = 0.21). In the unilateral cryptorchid men (ULC) group, there is no difference in paternity rates when compared with the controls (P = 0.079) or when comparing ULC smokers to ULC nonsmokers (P = 0.35). In the bilateral cryptorchid men (BLC) group, there is no difference in paternity rates when compared to controls (P = 0.075) or when comparing BLC smokers to BLC nonsmokers (P = 0.36). When comparing according to consumption, there is no difference between mild, moderate or heavy smoker cases and controls.
Conclusion
There is no difference in paternity rates between men with a history of cryptorchidism that consume tobacco compared to nonsmokers or controls. More studies are needed to determine the impact of tobacco consumption in formerly cryptorchid men.
