Objective-In this prospective study, we aimed to determine the efficac
y of doxycycline and doxycycline plus ceftriaxone for the treatment of
asymptomatic men with leukocytospermia. Method-Seventy men were inclu
ded in this randomized and placebo-controlled study. White blood cell
(WBC) concentrations were determined by peroxidase assay during the ro
utine semen analysis. Twenty-four of 70 men with leukocytospermia were
randomized as control group and administered placebo (group I), 25 re
ceived doxycycline alone (group II), and 21, doxycycline plus ceftriax
one (group III). Doxycycline, 100 mg, was given twice a day for ten da
ys and ceftriaxone, 1 g, in two doses for only one day. After the trea
tment, semen analyses were repeated. Results-After the treatment there
was a significant decrease in WBC counts in groups II and II when com
pared with group I (P < .05). Both antibiotic regimens were found to b
e equally effective. However, the time needed for resolution of leukoc
ytospermia (similar to 4 weeks) was similar between the control and tr
eatment groups. Conclusion-Although both antibiotic regimens significa
ntly, and equally improved the white blood cell counts in men with leu
kocytospermia, they failed to treat the leukocytospermia, i.e., to bri
ng the count below the limit of one million WBC/mL. Therefore, it is d
oubtful that antibiotic therapy should be recommended for asymptomatic
men with leukocytospermia.
