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. |
