Thiamine compounds in human semen.

The samples were from 12 healthy men aged from 25 to 42 years. The abstinence time was 3±1 days and the delay between ejaculation and freezing of the samples was 60±30 min. Seminal fluids were obtained by centrifugation (500× g, 10 min). The results are expressed as mean ± SD. The numbers in parentheses indicate the number of patients. We did not find any significant effects of the delay before freezing on the contents of thiamine derivatives.
