The study’s goal, according to the authors, was to ascertain how men’s sex hormone levels changed following ejaculation.
Every day throughout the abstinence period following ejaculation, the serum testosterone concentrations of 28 male participants were measured.
“We discovered that there were not much changes in testosterone levels between the second and fifth days of abstinence.
Serum testosterone levels peaked on day seven of abstinence, at 145.7% of the baseline (P<0.01). There was no discernible regular fluctuation after the apex.
“The basis and start of the seven-day periodic phenomenon was ejaculation. Serum testosterone levels did not fluctuate on a regular basis in the absence of ejaculation.
