Men's health includes health aspects that are particularly relevant to men, such as testosterone levels, reproductive organs, and prostate health. It primarily focuses on conditions like low testosterone, male sexual dysfunction, infertility, benign prostatic hyperplasia, and prostate cancer while also considering transgender and nonbinary individuals in certain contexts.

Diet plays a crucial role in men's health by influencing body weight because obesity and cardiometabolic diseases like type 2 diabetes are associated with a higher risk of health issues. Maintaining a healthy body weight through diet is essential for reducing these risks.

Supplements for men's health often aim to enhance testosterone levels, sex drive, and erectile function, and popular options include saw palmetto, tribulus terrestris, fenugreek, maca, yohimbine, tongkat ali, and horny goat weed. However, the research supporting their effectiveness is limited.
