Nettle (Urtica dioica), particularly its root extract, has a long history of traditional use for supporting male reproductive health, especially in Europe and parts of Asia. Historically, nettle has been used for symptoms related to benign prostatic hyperplasia (BPH), a common condition affecting the male reproductive system in older men. Traditional herbal medicine systems, such as those in Germany, have incorporated nettle root alongside other herbs for urinary and prostate health.

Scientific studies on nettle’s efficacy are limited and often involve combinations with other botanicals (like saw palmetto). Some clinical research suggests nettle root may help alleviate lower urinary tract symptoms associated with BPH, but most evidence does not directly link nettle to improvements in libido, fertility, or other aspects of male reproductive function. The purported mechanisms include inhibition of sex hormone-binding globulin (SHBG) and interference with enzymes (such as aromatase and 5-alpha-reductase) involved in hormone metabolism, but robust clinical trials are sparse.

In summary, while nettle has a strong traditional reputation for supporting the male reproductive system, especially prostate health, the scientific backing for its effectiveness is moderate at best and focused mainly on BPH-related symptoms rather than broader reproductive health aspects.
