Alcohol consumption is linked to a lower chance of pregnancy

Research recommends women who are preparing to avoid alcohol during the second half of their menstrual cycle

Reducing alcohol consumption and pregnancy about the possibility to reduce alcohol consumption and pregnancy possibilities relatedresearch proposals prepared pregnant women to avoid alcohol in the second half of the menstrual cycle, research suggests that prepare pregnant women to avoid alcohol in the second half of the menstrual cycle, research suggests that prepare pregnant women in the second half of the menstrual cycle to avoid alcohol

A study on the relationship between alcohol consumption and pregnancy probability indicated that women who want to become pregnant should avoid heavy drinking
.

In the second half of the menstrual cycle, even moderate drinking will reduce the probability of pregnancy

On June 10, the study was published in the journal Human Reproduction, a reproductive medicine journal
.

The study investigated the relationship between alcohol intake and the ability to conceive.

A research team led by Kira Taylor, associate professor of the School of Public Health and Information Sciences at the University of Louisville, USA, analyzed data from the "Sinai Mount Sinai Female Office Staff Study"
.

The researchers recruited women between the ages of 19 and 41 from 1990 to 1994 and followed them up to 19 menstrual cycles

Heavy drinking is defined as drinking more than 6 drinks a week, moderate drinking is drinking 3-6 drinks a week, and alcoholism is defined as drinking more than 4 drinks a day
.

"Each glass" consists of 1/3 liter of beer (355 ml), 1 glass of wine (148 ml) or slightly less than two glasses of spirits (44 ml)

"We found that compared with non-drinkers, drinking a lot of alcohol at any stage of the menstrual cycle significantly reduces the likelihood of pregnancy
.

" Taylor said, this is important because some women who want to become pregnant may think that it is in the menstrual cycle Drinking at certain stages is “safe”

Studies have shown that during the luteal phase, which is the last two weeks of the menstrual cycle, before bleeding begins and during implantation, both heavy and moderate drinking are significantly associated with a lower probability of pregnancy
.

During ovulation—usually around the 14th day of the cycle, heavy drinking—whether heavy or heavy drinking, is significantly associated with a reduction in the probability of conception

Compared with people who do not drink alcohol, moderate and heavy drinking during the luteal phase will reduce the likelihood of pregnancy by approximately 44%, and heavy drinking during the ovulation phase will also significantly reduce the likelihood of pregnancy by 61%
.

However, the researchers emphasized that these are estimates and should be treated with caution

"Assuming that a typical, healthy, non-drinking woman in the general population has a 25% chance of getting pregnant during a menstrual cycle, then, out of 100 women, about 25 non-drinking women will be in a specific cycle.
Pregnancy, about 20 moderate drinkers can get pregnant, while only about 11 alcoholics can get pregnant
.

" Taylor said, "During the luteal phase, the effect of moderate drinking is more pronounced, and only 16 moderate drinkers will get pregnant

"Our study included only a few hundred women.
Although we believe that the results of the study strongly indicate that heavy or even moderate drinking can affect the ability to conceive, the exact percentage and numbers can only be regarded as rough estimates
.
" Taylor said
.

During the luteal phase, every extra day of alcohol abuse reduces the probability of pregnancy by 19%, and during the ovulation phase, the probability of pregnancy is reduced by 41%
.
The researchers found that there was no difference in the results of different types of alcohol
.

This study does not prove that drinking alcohol will reduce the probability of pregnancy, but only shows that drinking is related to pregnancy
.
The biological mechanism that may explain this association is that alcohol intake affects the process related to ovulation, so no eggs are released during ovulation; alcohol affects the ability of fertilized eggs to colonize the uterus
.

Limitations of this study include that not all women try to get pregnant; alcohol intake has increased since the beginning of the study, and the women in the study are on average slimmer than current women; this study uses self-reported data, Women may underreport their alcohol consumption; the influence of male partner drinking has not been evaluated
.

"Finally, the results of this study should not be interpreted as drinking alcohol can prevent pregnancy
.
In other words, alcohol is not contraceptive
.
Even if a woman drinks too much, she may become pregnant if she has unprotected intercourse
.
" Taylor concluded
