Rating (out of 5): 2

Royal jelly has a long history of use in traditional medicine, particularly in East Asian and some European herbal practices, as a tonic for general vitality and reproductive health. In the context of supporting the testes and male reproductive system, its use is primarily based on tradition rather than strong scientific evidence. Herbalists and practitioners of traditional Chinese medicine have included royal jelly in formulations intended to enhance fertility, libido, and hormonal balance, attributing these effects to its rich content of nutrients and unique proteins.

Scientific studies directly investigating royal jelly's effects on the testes or male reproductive health in humans are limited and mostly preclinical. Some animal studies have suggested potential benefits, such as improved sperm quality, increased testosterone levels, and protection against testicular oxidative stress; for example, a few studies in rats have reported increased sperm count and motility after royal jelly supplementation. However, these findings have not been robustly replicated in human trials, and the overall quality of evidence is low.

In summary, the use of royal jelly for supporting the testes is rooted more in tradition than in validated science. While preliminary animal data is intriguing, it is insufficient to confirm efficacy or safety for this purpose in humans.
