Boron is a trace mineral that has been investigated for its potential role in supporting the male reproductive system, particularly in regard to testosterone levels. Several small-scale human studies and animal research have indicated that boron supplementation may have a modest effect on increasing free testosterone levels in men. For example, a 2011 study published in the journal Biological Trace Element Research found that daily supplementation with 10 mg of boron for one week resulted in a significant increase in free testosterone and a decrease in estradiol in healthy male participants. Other studies have shown that boron can influence steroid hormone metabolism and may impact enzymes involved in hormone regulation.

However, the overall quality of the evidence is limited by small sample sizes, short study durations, and a lack of large randomized controlled trials. There is also insufficient evidence to directly link boron supplementation with improved fertility parameters, sexual function, or broader reproductive health outcomes in men. While boron is essential for general health and may play a role in hormone regulation, claims regarding its benefits for the male reproductive system are not fully substantiated and require further research.

In summary, there is some scientific evidence that boron supplementation can affect hormone levels associated with the male reproductive system, but the evidence is preliminary and not strong enough to warrant widespread clinical recommendations.
