Diet, exercise and the use of prenatal vitamins are main concerns for women hoping to become pregnant. Alcohol consumption is a lifestyle factor that is often queried.
Is the consumption of the occasional glass of wine harmless, or can it negatively affect the chances of becoming pregnant?
The health impacts of alcohol and female fertility have been researched for many years. The findings are often conflicting. While light or moderate drinking may not affect the fertility of some women, research is showing that alcohol may have a negative impact on hormones, ovulation, the quality of eggs, and even the efficacy of fertility treatments.
The aim of this article is to discuss the alcohol and female fertility research, how alcohol may negatively impact female fertility, and provide guidance for women who are planning to become pregnant.
The Factors that Determine Female Fertility
Multiple systems must work in conjunction for a woman to successfully conceive:
– Regular Ovulation
– Hormones in a Healthy Balance
– Quality Eggs
– Healthy Fallopian Tubes
– Uterus Prepared to Receive Embryo
– Mental and Physical Wellness
The disruption of any one of these systems can complicate or prevent conception. There are lifestyle habits that can negatively impact each of these reproductive systems, including the consumption of alcohol.
Alcohol and Female Fertility
Alcohol impacts the reproductive system, and many other systems including the endocrine (hormonal) system, and liver.
Since hormones are crucial to ovulation and conception, moderate alcohol consumption may also impact the fertility of some women.
Studies propose that alcohol may do the following:
– Change reproductive hormones
– Disrupt ovulation
– Impact egg quality
– Increase oxidative stress
– Impact implantation
– Reduce the success of reproductive assistance
– The effect is varying in each woman based on amount of consumption, frequency of consumption, age, and health.
Alcohol and Hormones
When the brain communicates properly with the ovaries, reproduction is successful. Alcohol can disrupt the communication.
Chronic alcohol consumption can disrupt:
Estrogen
When drinking the liver processes alcohol, resulting in the liver producing more estrogen. When there is an excess of Estrogen it can disrupt the menstrual cycle and the process of ovulation.
Progesterone
Progesterone prepares the uterus for implantation after ovulation. Chronic alcohol consumption may reduce Progesterone and create an unfavourable environment for implantation.
FSH
FSH is essential for the growth of ovarian follicles. Alcohol consumption can create a disruption of hormones that results in the reduction of egg maturation and follicle growth.
LH
LH is the hormone that triggers ovulation. Alcohol can create a disruption of LH and result in the delay or prevention of ovulation.
Alcohol and Ovulation
There are many obstacles to natural conception, and the disruption of regular ovulation is one of the most significant. Multiple studies find that alcohol can disrupt regular ovulation, particularly in women who are habitual drinkers.
The results may include:
– Delayed ovulation
– Irregular menstrual cycles
– Absence of ovulation
– Increased time to conceive
Irregular cycles of ovulation may be even more pronounced with alcohol consumption.
Alcohol and Egg Quality
Egg quality is one of the main factors in successful reproduction.
The natural ageing process causes the quantity and quality of a woman’s eggs to diminish. Of note, the consumption of alcohol has the following effects:
1. Heightened oxidative stress
2. Damaged cells
3. Decreased mitochondrial functioning of eggs
4. Damaged reproductive cells’ DNA of Alcohol may cause
While infrequent alcohol consumption is not likely to have long lasting effects, heavy and frequent alcohol consumption may cause faster ageing of the reproductive system and loss of reproductive capacity.
Can Moderate Drinking Affect Fertility?
This is a highly contentious issue among those in reproductive medicine. There are studies showing little effect of light alcohol consumption on a woman’s fertility while other studies show a negative correlation, whereby moderate alcohol consumption is associated with lower rates of conception.
Moderate behaviour is generally viewed as having only one alcoholic beverage within a 24 hour period. It is generally advised to restrict or completely abstain from alcohol when attempting to conceive since:
1. There are no positive effects on fertility
2. The potential negative effects are not worth the limited time enjoyment
3. The early stages of pregnancy is often undetectable to the woman.
To be on the safe side, it is preferred to have a better chance or conceiving and not engaging in higher risk behaviour.
Consuming Alcohol Heavily and Its Impact on Female Fertility
There are a number of detrimental reproductive effects of heavy alcohol consumption that are interlinked.
Some of these effects are:
1. Difficulty conceiving
Women who heavily consume alcohol have been shown in studies to take longer to conceive than women who do not consume alcohol.
2. Abnormal menstrual cycles
Alcohol has the potential to interrupt the hormones and create irregular or absent menstrual cycles.
3. Poor formation of ovaries
The chronic abuse of alcohol has been shown to lower the number of healthy eggs in a woman.
4. Greater risk of miscarriage
High alcohol consumption during early pregnancy increases the chances of pregnancy loss.
Early Menopause
Excessive alcohol consumption over the years may cause early aging of the ovaries.
Alcohol and IVF Success
Alcohol consumption should be limited during IVF. Alcohol can impact:
- Egg retrieval, Egg quality, Fertilization, Embryo quality, Implantation, and Live birth.
- Alcohol, even in small amounts, can lead to decreased IVF success.
- Many clinics advise no alcohol during IVF and the early stages of pregnancy.
Alcohol and Implantation
A healthy embryo can implement a healthy pregnancy.
Alcohol can impact implantation by:
- Changing hormones, Increasing inflammation, Changing blood flow to the uterus, and Decreasing endometrial receptivity.
- Studies are ongoing and the healthiest choice is to avoid alcohol during the time of conception.
Alcohol and Pregnancy
- Many pregnancies are unplanned. Other pregnancies are detected weeks after the act of conception.
- During early fetal development, many women are unaware that they are pregnant.
- Health care professionals suggest that women avoid alcohol when they are trying to conceive.
- This can help prevent early fetal development issues and maintain healthy hormone and reproductive systems.
Can Drinking Cause Infertility?
Occasional consumption of alcohol is unlikely to cause infertility in women.
However, fertility is affected by proper timing, healthy hormones, and many biological processes.
Because the use of alcohol during the period of trying to conceive has the potential to disrupt the functions of the body systems involved with fertility, the highest degree of confidence can be obtained when alcohol is completely eliminated during this period.
Women who are experiencing problems with fertility or are facing the prospect of delayed conception are urged to discuss their alcohol consumption with a member of their healthcare team.
Lifestyle Factors That Improve Female Fertility
There are many factors that influence fertility, of which alcohol consumption is just one.
The following lifestyle choices are also considered to have a positive influence.
Maintain a Healthy Weight
Obesity and underweight can have a negative impact on the balance of hormones and on ovulation.
Eat a Balanced Diet
Take special note of the following in your diet:
– Fruits
– Vegetables
– Whole grains
– Lean protein
– Healthy Fats
– Omega-3 Fatty Acids
Exercise Regularly
Regular exercise is important for the balance of body systems and the regulation of hormones. Over excessive exercise can have the opposite effect.
Quit Smoking
Egg and Ovarian Reserve quality are adversely impacted by smoking.
Manage Stress
Chronic stress may also lead to an imbalance of body systems. Its influence on fertility is very limited.
Get Enough Sleep
Sleep is restorative and has a positive influence on body systems and hormones.
Should Your Partner Also Avoid Alcohol?
Alcohol consumption among couples trying to conceive can also negatively impact Male Fertility because of its influence on the following:
– Sperm Count
– Sperm Motility
– Sperm Morphology
– Testosterone
– Sperm DNA
The consumption of alcohol should be avoided as a measure to positively influence the chances of conception during this time.

Conclusion
The link between alcohol and female fertility is complicated, but the evidence suggests being careful. Hormones and alcohol do not mix well. Heavy alcohol use has been shown to result in disrupted hormones, erratic ovulation, poor egg quality, and low rates of pregnancy. While the occasional or moderate drink has little effect on some women, there is no positive outcome for fertility from alcohol use.
When trying to conceive, the best choice for fertility is to cut back or eliminate alcohol. The early months of pregnancy are full of unknowns, and cutting back on alcohol is a potential way to reduce the potential risks. Alcohol use is one of many aspects of a healthy lifestyle. A healthy lifestyle can create the best possible conditions for pregnancy.
Every fertility journey is different. If you are concerned about alcohol use and infertility, or have other questions, a healthcare provider is the best resource. They can assess your health and fertility and provide you with personalized and relevant information.
FAQs
Decreased fertility, hormonal imbalance, and erratic ovulation patterns are commonly reported among heavy drinkers, leading to lower rates of successful pregnancies. The research is inconsistent, but some women may experience fertility challenges due to even moderate alcohol consumption.
Many fertility experts recommend total alcohol abstinence while trying to conceive. There may be consequences to the reproductive system due to alcohol consumption. Pregnancy is often not recognized for some time, meaning there is a possibility of drinking during the early weeks of alcohol-free baby-making, and that time is not without alcohol-related consequences to the baby and the mother’s system.
An occasional drink, while trying to conceive, is not likely to cause infertility, but the best approach with the most consensus among experts is likely to be the total or almost total avoidance of alcohol.
It is possible that heavy, chronic, and long-term alcohol consumption may increase oxidative stress and contribute to lower quality eggs. The impact of moderate or occasional alcohol consumption during that same time is unclear.
