Subjects and methods: formerly unilateral cryptorchid men who had undergone orchiopexy between the years of 1955 and 1975 at the children’s hospital of pittsburgh and a control group of men who were matched for age of an unrelated surgery at the same institution were evaluated by review of medical records and by completion of a questionnaire. 359 previously cryptorchid men were identified as having attempted paternity. Of these men, 320 had information concerning preoperative testicular location and 163 for preoperative testicular size. buy viagra canada 106 of these men had levels of testosterone, inhibin b, fsh, and lh measured, while 95 of the men had semen analyses. viagra 25 mg or 100mg Results: among men who had attempted paternity, there was no statistical difference in success of paternity between the previously unilateral group (89. 7%) and the control group (93. 7%). There was no difference in the mean time to conception (7. 1 ± 0. jalea real viagra natural 7 months for the unilateral group vs. 6. efficacy viagra daily use 9 ± 2. 3 for the control group).
