The Claim
It is often believed that selenium can improve male fertility due to its role in sperm production and quality. Some claim that supplementing with selenium can enhance sperm motility and count.
Origin
This belief is partly based on animal studies and a few small-scale human trials that showed improvements in sperm parameters with selenium supplementation.
What Science Says
While some small studies suggest selenium might improve certain sperm parameters, larger and more rigorous studies are needed to confirm any real benefit. A systematic review indicates mixed results, and the overall evidence is not strong enough to support selenium as a reliable fertility treatment.
Verdict
Partially True
