Eat meat? Here's how it may affect your testosterone levels

A new Finnish study of 2,546 men found a link between dietary protein source and testosterone levels: animal protein was associated with about 8% lower levels, while plant protein was linked to about 7% higher levels.

A new study from Finland has found a link between dietary protein source and testosterone levels in men. Researchers examined the diets of 2,546 men aged 42 to 60 over four days and found that high consumption of animal protein, mainly meat, was associated with testosterone levels about 8% lower than average. In contrast, a diet rich in plant protein, such as legumes, nuts, and whole grains, was linked to levels about 7% higher. The researchers hypothesize that plant protein may reduce inflammatory processes, which negatively affect testosterone secretion. It was also found that consumers of plant protein tended to be more physically active, consumed more fruits and vegetables, and smoked less.
