Can BDNF help with fertility?

The question of whether BDNF (Brain-Derived Neurotrophic Factor) can help with fertility is not addressed in the provided context. From a broader scientific perspective, BDNF is known to be expressed in reproductive tissues and may influence oocyte maturation, sperm quality, and embryo development. However, these findings come mainly from animal and in vitro studies. There are no robust human clinical trials showing that increasing BDNF levels—through supplements, exercise, or genetic variants—improves fertility outcomes. Direct-to-consumer tests that claim to link BDNF SNPs to fertility are speculative. The evidence level is mechanistic at best, not clinically actionable. Anyone concerned about fertility should consult a medical professional rather than rely on unvalidated biomarker tests.
