Research tied to sperm markers, motility, and male hormone outcomes.
Sperm count, motility, and hormone levels differ from pregnancy and birth outcomes. A laboratory change does not establish that the latter improved.
Distinguish fertility-treatment participants from a general population. Multi-ingredient trials may not isolate a single ingredient's contribution.
These findings come from sperm, semen, or hormone markers such as testosterone, LH, FSH, and inhibin B. They are closer to research measurements than a directly felt benefit.
No direct evidence for general supplement use is confirmed under the current standard.
