[Seminal fluid concentration of ketoconazole and its effect on spermatozoa motility]
Abstract:
The concentration of Ketoconazole in seminal fluid has been measured in 7 men. The average concentration of 150 ng/g in seminal fluid is much lower than in blood plasma, but for the treatment of candidiasis the concentration in seminal fluid may be too low. A 50-fold higher Ketoconazole-concentration did not disturb sperm motility in 24 men. Therefore there may be no danger for motility of sperms in genital tract of women, for the tested Ketoconazole-concentration was 3-fold higher than the blood serum concentration.
