Women who drink a lot of alcohol have difficulty conceiving – VnExpress


The more alcohol a woman drinks, the lower her chances of conceiving, due to hormonal disturbances that lead to irregular menstrual cycles, delayed or no ovulation.

Most women know that drinking alcohol can harm their unborn baby before they even know they’re pregnant. In fact, there is no established safe level for alcohol intake during pregnancy. What many women may not know is that drinking alcohol in moderation during the middle and second half of the menstrual cycle can also reduce the chances of a successful conception.

According to a new study on alcohol drinking patterns and hormone levels at different stages of the month, drink alcohol in moderation (3-6 drinks per week) and heavy (more than 6 drinks per week) in the later stages. Ovulation of the menstrual cycle can disrupt the delicate hormonal sequence needed to conceive. Researchers have also found that heavy drinking early in a woman’s cycle, during ovulation, can disrupt conception.

“The takeaway from our study is that if you want to get pregnant, don’t drink more than one drink a day at any time during your menstrual cycle, and drink less than half a glass during ovulation and.” after ovulation,” said Dr. Kira C. Taylor, associate professor of epidemiology and population health at the University of Louisville in Kentucky, USA.

“The effects of alcohol on fertility have been suspected since the 1990s but have not been well studied,” says Nishath A. Ali, MD, associate professor of obstetrics and gynecology and gynecology at Baylor College of Medicine in Houston, US. , adds. “Moderate to heavy drinkers often take longer to conceive and are at high risk for infertility evaluation.”

Currently, women undergoing fertility treatments such as IVF are advised to cut back on alcohol consumption.

The study, which began in 2017, looked at the correlation between alcohol and the likelihood of pregnancy during a menstrual cycle. Experts analyzed data from 413 women, aged 19 to 41. They kept daily records of how much and how much alcohol they drank for up to 19 months of follow-up. Participants were predominantly white, non-Hispanic, and married.

Study participants also submitted monthly urine samples to assess pregnancy status, and their monthly cycle stages were calculated using a calendar-based method and compared between drinkers and non-drinkers. drink alcohol.

During the study, 133 women became pregnant, and the results showed that the more alcohol a woman drank, the less likely she was to conceive.

“In heavy drinkers, the probability of conception is 27.2%, increasing to 41.3% in non-drinkers. Light and moderate drinkers have about a 32% chance of conceiving,” he said. Taylor said.

When researchers looked at the effects of alcohol consumption during different phases of the menstrual cycle, they found that moderate and heavy drinking in the post-ovulatory period reduced near-term conception rates. half (44% and 49%), respectively, compared with non-drinkers. There is also some suggestion that drinking a lot of alcohol before ovulation also reduces the chances of conception.

Notably, drinking too much alcohol in a short period of time can reduce your chances of conceiving by 19% around the time of ovulation and between ovulation and menstruation. The researchers also found that the results did not change with all alcoholic beverages.

Christine Metz, PhD, professor at the Institute of Health Research in Manhasset, New York, said: “In addition, research shows that menstrual cycle length is the same for women across all beverages, showed that drinking alcohol did not affect the hormones that regulate cycle length.

The authors suggest that part of the link between conception and alcohol may be due to disturbances in steroid hormones, particularly an increase in estradiol, a form of estrogen. “An increase in estrogen can lead to irregular periods, delayed ovulation or no ovulation. An increase in estrogen can also affect the time it takes for the lining of the uterus to implant after fertilization.” , Dr. Taylor said.

Men are no exception, because their testicles can also be affected by drinking alcohol.

“High alcohol consumption has been linked to abnormalities in gonadal function in men, including decreased testosterone and decreased sperm count,” Ali said. “Lifestyle changes are important for both spouses planning a pregnancy.”
