Does high sugar consumption impact testosterone?

High sugar consumption potentially impacts testosterone levels through various mechanisms. Excessive sugar intake can lead to insulin resistance, disrupting hormonal balance and reducing testosterone production. Additionally, sugar consumption contributes to chronic inflammation, which may interfere with the hypothalamic-pituitary-gonadal axis, further affecting testosterone synthesis.

Obesity, often linked to high sugar intake, can exacerbate the problem as adipose tissue converts testosterone to estrogen. A study published in Reproductive Biology and Endocrinology (2018) explored this connection. Examining US males aged 20–39, the study found a negative association between sugar-sweetened beverage intake and serum testosterone levels. In conclusion, reducing sugar consumption may help maintain healthy testosterone levels and mitigate associated health risks.
