Apparently Buddhist monks have known it for centuries – that eating soy reduces male libido. If you’re a monk then consuming tofu morning, afternoon and night will allow you to experience less ‘distraction’ from sexual urges which are, after all, natural.
A study from the British Journal of Nutrition reported that replacing meat with 290g of tofu in a man’s diet for only 4 weeks can changes their balance of estrogenic hormones to testosterone. The result is that men have more estrogens in relation to testosterone in their body because their testosterone levels are lowered. The latter can reduce a man’s libido.
Decreased intake of fat, increased dietary fibre and changing to a vegetarian diet also lower the levels of testosterone and other androgens. Eating soy also noticeably reduces the concentration of sperm in male human semen by 41 million sperm per milliliter of semen.
Soy is found in many processed foods, so as usual the advice is to read the label.
