LCT determines adult lactose digestion capacity. Lactose intolerance may cause gastrointestinal discomfort, potentially impairing absorption of calcium and vitamin D—both relevant for reproductive health. Some observational studies suggest a possible association between dairy intake and ovulatory fertility, but they rarely genotype LCT. The data are inconsistent: adequate calcium may support oocyte quality, yet no randomized trials directly connect LCT variants to fertility outcomes. Effects are confounded by vitamin D status, gut microbiome, and inflammation. Consumer DNA tests that promote LCT in a fertility context often overstate the evidence. Conclusion: LCT is not an established fertility marker; however, personalized dietary advice for lactose intolerance can help prevent nutrient deficiencies.","area":"gesundheit","canonical_id":"gesundheit:canonical-85c05bd0d467eb8bc43b76cc","id":"public-47c9881e7d1b967a73e9c8fc","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: LCT in the context of Fruchtbarkeit","score":23.87267833,"snippet":"The evidence for a direct link between the LCT genotype (lactase persistence/non-persistence) and fertility is weak and indirect.
