The purpose of this study is to gain understanding of the relationship between ejaculation and serum testosterone level in
men. The serum testosterone concentrations of 28 volunteers were investigated daily during abstinence periods after ejaculation
for two phases. The authors found that the fluctuations of testosterone levels from the 2nd to 5th day of abstinence were
minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, reaching 145.7% of the baseline
(P<0.01). No regular fluctuation was observed following continuous abstinence after the peak. Ejaculation is the precondition
and beginning of the special periodic serum testosterone level variations, which would not occur without ejaculation. The
results showed that ejaculation-caused variations were characterized by a peak on the 7th day of abstinence; and that the
effective time of anejaculation, is 7 days minimum. These data are the first to document the phenomenon of the periodic change
in serum testosterone level; the correlation between ejaculation and periodic change in the serum testosterone level, and
the pattern and characteristics of the periodic change. 相似文献
