The impact of plant-derived estrogenic compounds on male hormonal balance: risk assessment and mechanistic pathways
Isoflavones found in soy-based products, notably genistein and daidzein, exhibit the capacity to bind with estrogen receptors, which under conditions of excessive exposure may lead to endocrine disruptions. While occasional consumption of soy-derived foods—such as soy patties or tofu dishes—does not pose a significant threat to hormonal equilibrium, the chronic intake of high phytoestrogen doses, particularly within a vegan diet where soy serves as the primary protein source, can suppress testosterone synthesis. The consequences of such hormonal imbalance may include increased adipose tissue deposition, reduced vitality, diminished libido, and in severe cases, infertility. An additional compound that adversely affects testosterone levels is D-asparagic acid (DAA), commonly incorporated into dietary supplements targeted at physically active individuals, especially those designed to accelerate muscle hypertrophy. Men seeking to maintain an optimal androgenic profile should exercise caution regarding excessive supplementation, instead prioritizing natural testosterone-boosting strategies such as consistent, balanced resistance training without pharmacological intervention.
