"High SHBG is an issue for people such as men and athletes who need a lot of free testosterone. In men, elevated SHBG levels are associated with erectile dysfunction, lower libido, and infertility. In both sexes, low testosterone can impair workout recovery and reduce muscle growth. Furthermore, elevated SHBG may decrease the amount of free estrogen in the blood, reducing bone mass and potentially leading to osteoporosis.

Vegetarians are more likely to suffer from elevated levels of SHBG than non-vegetarians. In a 2009 research study, researchers recruited 21 healthy middle-aged omnivore women and 19 healthy vegetarian/vegan middle-aged women for a year-long study. Researchers had the women participate in 1-3 hours of exercise per week and made sure they consumed equal amounts of protein. At the end of the study, scientists observed equal similar levels of total testosterone in the omnivores (1.76 nmol/L) and vegetarians (1.79 nmol/L). 11

In contrast, the vegetarians had 50% higher SHBG than the omnivores (46 nmol/L vs. 69 nmol/L). These findings suggest that a vegetarian-based diet high in protein substantially increases SHBG without changing total testosterone, thus leading to a potential decrease in free testosterone."
