Science or Snake Oil: do men need sperm health supplements?

Infertility, defined as the inability of a couple to conceive after at least 12 months of regular, unprotected sex, affects about 15% of couples worldwide. Several factors can lead to infertility, but specific to men, infertility has been linked to lower levels of antioxidants in their semen. This exposes them to an increased risk of chemically reactive species containing oxygen, which can damage sperm.

These reactive oxygen species are naturally involved in various pathways essential for normal reproduction. But uncontrolled and excessive levels of reactive oxygen species results in damage to your cells (or “oxidative stress”). This can affect semen health, and damage the DNA carried in the sperm, leading to the onset of male infertility.
