[Correlation of detection of Chlamydia infection of the urethra sperm].

In the group of 150 men with urological diseases simultaneous examinations of urethra swabs and sperm specimens were done. By culture method on McCoy cells Chlamydia trachomatis was found more frequently in semen (46.7%) than in urethra (35.3%); in 103 patients with urethritis the results were 43.6% and 33.0% respectively. Consistently positive results were obtained in 33 (26.0%) and consistently negative ones in 66 (44.05) of all examined men. In 31 (20.7%) patients, 22 with urethritis including Chlamydia trachomatis was cultured from semen alone and in 14 (9.3%) from urethra alone. The above findings suggest that human semen constitutes a valuable diagnostic material in cases suspected of infection due to Chlamydia trachomatis.
