Sexual Function and Fertility in Patients Treated for Posterior Urethral Valves

We interviewed 21 men treated in infancy for posterior urethral valves about their sexual function. Of the men 10 provided semen samples (1 of which was incompletely analyzed) and 7 provided urine voided after masturbation. Erections and orgasm were normal in 20 men and 1 had lifelong impotence. Nine men had slow or dry ejaculation. There was no evidence on urinalysis of retrograde ejaculation except in 1 patient. Semen counts were within the fertile range. Of 9 patients 5 had viscous semen with a pH of more than 8.0. Three patients had initiated pregnancies.
