Rating (out of 5): 3

Stinging nettle (Urtica dioica) is commonly used in herbal medicine to support the male reproductive system, particularly for prostate health. Scientific evidence mainly centers on its role in managing symptoms of benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate gland that can affect urinary and sexual function in men. Several clinical trials and reviews have indicated that nettle root extract, often in combination with other herbs like saw palmetto, can modestly reduce BPH symptoms such as increased urinary frequency and nocturia. The mechanism appears to involve inhibition of sex hormone-binding globulin and interference with inflammatory pathways, which may reduce prostate tissue growth and inflammation.

However, the evidence is mixed: while some studies report statistically significant improvements in BPH symptoms, others note only modest benefits or question the methodological quality of the research. There is less direct evidence regarding nettle’s effects on other aspects of the male reproductive system, such as testosterone levels or fertility. Most scientific support is therefore specific to prostate health, rather than broad reproductive enhancement. In summary, stinging nettle has scientific support for prostate-related benefits in men, meriting a moderate evidence rating, but further high-quality studies are needed to clarify its full range of effects on the male reproductive system.
