After analysing data from the Mount Sinai Study of Women Office Workers, Researchers from the University of Louisville School of Public Health and Information Sciences in the US confirmed that there is a connection between alcohol consumption and fertility struggles.
The four-year study collected information from more than 400 women aged 19 to 41, particularly data related to their menstrual cycles and drinking habits.
The women completed daily diaries reporting how much alcohol they drank and provided urine samples on the first and second day of each menstrual cycle.
A reduced probability of conception
According to the study, heavy drinking was defined as more than six alcoholic drinks a week, moderate was three to six, and binge drinking was defined as four or more drinks every day.
Heavy drinking on any day of the menstrual cycle was significantly associated with a reduced probability of conception compared to non-drinkers, especially during the luteal phase, which is the last two weeks of the menstrual cycle.
Moderate and heavy drinking during the luteal phase was linked to a reduction in the odds of conceiving by about 44%. Consuming more than six alcoholic drinks a week during ovulation was associated with a 61% reduced odds of becoming pregnant.
