The consensus among health experts is that the safest approach is to abstain from alcohol entirely when trying to conceive and throughout the entire duration of pregnancy to eliminate any risk to the developing fetus.
The research indicates that even light or moderate drinking before pregnancy can have detrimental effects on fetal development and growth. Alcohol consumption prior to pregnancy has been linked to increased risks of miscarriage, low birth weight, preterm birth, and fetal alcohol spectrum disorders.
Hence, both women and men should abstain from any alcohol consumption when planning a pregnancy, to safeguard the health of the developing fetus from potential alcohol-related harms.
