The team examined the effect of alcohol on fertility on 135 women aged 18 to 44 years and measured their ovarian reserve.
This is the ovaries' capacity to make healthy egg cells, which is measured by counting the antral follicles that produce them.
Antral follicle count (AFC) is the standard way of assessing a woman's fertility and the typical number for a woman in her 30s is around 12 or 13, but this decreases over time.
Lead researcher Dr Ashley Eskew said the impact of lifestyle, including dietary patterns, and alcohol intake on ovarian reserve are conflicting as the objective of the study was to determine if alcohol intake is associated with ovarian reserve as determined by AFC.
The researchers explained the link may be down to resveratrol, an anti-inflammatory compound, which occurs in high concentration in red wine.
The findings will be presented at the American Society for Reproductive Medicine in San Antonio, Texas, next week.
"However we have to remember that the exposure of the developing foetus to alcohol may cause irreversible developmental damage and so alcohol consumption should be less than six units per week for women wishing to conceive," Balen added. (ANI)
