I was looking over this website(www.bodybuilding.com) and I read an interesting "small" text about sex and testosterone. So I want to know if this information is true... or just an urban myth?
Chinese researchers conducted a study in 2003, and enlisted twenty-eight male volunteers to abstain from ejaculation for a period of one week. The participants were tested daily for deviations on serum testosterone levels. The Chinese study was the first to measure the influence of ejaculation frequency on serum testosterone levels, and the results are provocative.
Researchers found that abstaining from ejaculation for six days had no impact on serum testosterone levels. On the seventh day, serum testosterone levels peaked to 145.7% of baseline, and then declined rapidly on the eighth day.7,8
Researchers believe testosterone declined on day eight from the negative feedback suppression of Leutinizing hormone secretion. Leutinizing hormone is essential for testosterone production, and LH determines free testosterone levels. Suppression of LH would decrease serum testosterone levels, returning them to baseline. The study determined that the frequency of sexual activity and ejaculation impacted testosterone levels.
