Evidence check: LCT in the context of fertility

The LCT genotype determines lactase persistence, i.e., the ability to digest lactose. In the provided context, there is no evidence linking LCT variants to fertility. While some external studies explore indirect effects via diet or gut health, the evidence is weak and inconsistent. Without specific data from your query, any claim connecting LCT to fertility remains speculative. A DNA test alone cannot provide fertility insights. Consult a reproductive specialist for fertility concerns.
