Alcohol and infertility in females and males

Written by Brandon Okey. Mina Draskovic, B.Psy., reviewed this content for accuracy.

Many couples struggling to conceive don’t realize their drinking habits could be sabotaging their efforts because alcohol damages reproductive health in men and women, even at moderate consumption levels.

Alcohol reduces conception chances by up to 50% during any given cycle, with effects lingering for months after the last drink. Researchers from the University of Copenhagen show that even five or fewer alcoholic beverages per week significantly reduce a woman’s chances of becoming pregnant. Even light drinking can disrupt hormonal balance in women, interfere with ovulation, and create a hostile environment for implantation. For men, alcohol lowers testosterone, reduces sperm count, and damages sperm quality.

Ardu is here to support your journey to sobriety and restored fertility. Our evidence-based alcohol rehabilitation programs address the root causes of addiction while providing the medical support, counseling, and community you need to achieve lasting sobriety in a judgment-free environment.

Can alcohol cause infertility in men?

Alcohol is a powerful reproductive toxin that can significantly reduce a man’s ability to father a child. From lowering hormones to directly damaging sperm cells, drinking—especially heavy or frequent consumption—inhibits fertility.

Alcohol consumption impairs male fertility through several mechanisms:

Decreased testosterone production: Alcohol inhibits the cells in the testes that produce testosterone, which is essential for sperm production and maturation. A 2015 study shows testosterone levels can drop by over 80% with chronic alcohol consumption, leading to decreased sperm count, reduced motility, and ultimately, significant fertility challenges.
Hormonal imbalances that disrupt reproductive function: The shift toward higher estrogen and lower testosterone levels disrupts the signals between the brain and testes that regulate sperm development.
Direct damage to testicular tissue: Alcohol and its byproducts are toxic to testicular tissue, causing direct damage to the delicate structures where sperm forms. Emanuele and Emanuele demonstrate that chronic drinking damages testicular tissue through increased lipid peroxidation, dramatically reducing sperm quality and quantity. 40% of alcoholic men have lower sperm counts and 45% produce abnormally shaped sperm, significantly compromising their fertility.
Reduced sperm count and quality: Men who drink regularly often have lower sperm counts, poor sperm movement, and abnormally shaped sperm.
Increased oxidative stress that harms sperm cells: Drinking increases harmful reactive oxygen species (ROS) in the reproductive system, which damages sperm cell membranes and DNA. According to a 2023 study, sperm cells are particularly vulnerable to oxidative damage because they possess limited antioxidant defense mechanisms. ROS attack and cause oxidative lesions in sperm DNA strands, leading to sperm DNA fragmentation, impaired fertility, and increased risk of developmental abnormalities in offspring.
Sexual performance issues including erectile dysfunction: Alcohol can cause erectile difficulties and reduced libido. According to research, “the quantity of alcohol consumed appeared to be the most significant predictor of developing sexual dysfunction.” Erectile dysfunction and low sexual desire are major impacts of alcohol on fertility, with 33.3% of alcohol-dependent men reporting difficulty achieving or maintaining erection and 36% reporting low sexual desire.

The path to restoring male fertility after alcohol use isn’t always straightforward. Many men need comprehensive support to achieve lasting sobriety and reproductive health. Our specialized men’s alcohol rehab and detox program addresses the root causes of dangerous alcohol use in men through medical care, therapy, and personalized counseling.

We will help you safely overcome alcohol dependence, understand how drinking affects your reproductive system, and develop healthy habits that support both sobriety and fertility restoration.

Does alcohol affect sperm when trying to get pregnant?

When actively trying to conceive, even moderate drinking reduces your chances of successful conception by compromising sperm quality. Among men drinking more than 20 units of alcohol weekly, time-to-pregnancy was significantly longer for their partners, indicating direct impairment of conception chances. Sansone, et. al. reported that increased alcohol consumption was associated with reduced live birth rates, showing a 21% decline in successful outcomes for couples where both partners drank more than 4 units per week.

If you’re serious about conception, reduce or eliminate alcohol. Reproductive hormones and semen quality can begin improving within weeks of sobriety and offer a relatively quick way to enhance fertility when trying to conceive.

How long does alcohol affect sperm?

The timeline of alcohol’s effects on sperm varies based on drinking patterns. Acute effects appear almost immediately, with a single night of heavy drinking potentially impairing sperm quality for several days. For regular drinkers, sperm parameters remain compromised as long as drinking continues.

Recovery begins once drinking stops. Light or moderate drinkers may see improvements within 1–3 months, the time needed for new, healthier sperm to develop and mature. For heavy, chronic drinkers, full recovery can take 3–6 months or longer.

Unlike some infertility causes, alcohol-induced sperm damage appears largely reversible. Many men see significant improvements in sperm count, motility, and morphology within just a few months of sobriety.

How does alcohol affect fertility in women?

Women’s reproductive systems are equally, if not more, vulnerable to alcohol’s damaging effects. A woman’s fertility relies on precise hormonal signals, perfectly timed ovulation, and a receptive uterine environment. Alcohol disrupts this intricate biological choreography and creates obstacles to conception that many women don’t realize until they’re actively trying to become pregnant.

A prospective cohort study found that women who consumed moderate levels of alcohol (1–5 drinks per week) had 39% lower odds of becoming pregnant than those who abstained. Women who engaged in heavy alcohol consumption (more than 10 drinks per week) experienced a 66% decrease in their chances of conceiving.

Here’s how alcohol sabotages female fertility:

Hormonal imbalances: Even moderate drinking disrupts the reproductive hormones necessary for ovulation and implantation. A 2002 study by Emanuele, et. al. found that “alcohol ingestion at the wrong time, even in amounts insufficient to cause permanent tissue damage, can disrupt the delicate balance critical to maintaining human female reproductive hormonal cycles and result in infertility.”
Menstrual irregularities: Alcohol can lead to irregular cycles, anovulation (cycles without egg release), and luteal phase defects that prevent successful conception. Emanuele, et. al. maintain that “alcohol ingestion, even in amounts insufficient to cause major damage to the liver or other organs, may lead to menstrual irregularities.”
Impaired implantation: Alcohol changes the uterine environment, making it less receptive to a fertilized egg and reducing the chances of successful implantation. De Angelis, et. al. theorize that alcohol damages early pregnancy development by reducing the growth of essential embryo-supporting cells while simultaneously causing more of these cells to die off prematurely.
Increased risk of miscarriage: Alcohol consumption during the conception period can disrupt the earliest stages of pregnancy by impairing proper implantation of the fertilized egg and interfering with hormonal balances. Many women experience early miscarriages before they even realize they’re pregnant, and alcohol’s toxic effects on developing embryonic cells can increase this risk substantially.
Reduced success with fertility treatments: Drinking lowers success rates for assisted reproductive technologies such as IVF and IUI. According to a 2020 study, women who stopped drinking or cut back on alcohol before fertility treatments were more likely to get pregnant than women who kept drinking the same amount.
Earlier onset of menopause: Heavy drinking is associated with diminished ovarian reserve and earlier transition to menopause, which reduces the reproductive window. Kwon, et. al. indicate that alcohol increases menopausal vasomotor symptoms (hot flashes and night sweats) in premenopausal women. They also provide evidence that moderate alcohol consumption over time raises FSH levels and reduces ovarian volume in women before menopause, indicating a reproductive decline in ovarian function.

The inflammation caused by drinking affects reproductive tissues in women by interfering with the uterine environment necessary for successful embryo implantation. There’s also the disrupted metabolism caused by alcohol—unique changes in fat distribution and insulin sensitivity that can further impair fertility.

Alcohol provides zero health benefits for women, particularly damaging reproductive function. If you’re concerned about your alcohol use while trying to conceive, we offer specialized rehabilitation programs that address these interconnected challenges.

Can alcohol affect pregnancy during ovulation?

Ovulation is the critical window when conception is possible, but alcohol can sabotage your fertility window. When a woman drinks around ovulation time, alcohol interferes with the luteinizing hormone (LH) surge that triggers egg release. Back in 1997, researchers knew that alcohol blocks the LH surge in female rats during the critical proestrus phase, effectively preventing ovulation.

Even moderate alcohol consumption can reduce a woman’s chances of getting pregnant, with as little as five drinks per week lowering fertility. Researchers observed that alcohol intake around ovulation (days 14–21 of the cycle) was particularly harmful because it interferes with important reproductive processes. If you’re trying to conceive, avoid alcohol entirely.

Does alcohol affect conception and implementation?

Alcohol disrupts the chances of conception and implantation. A 2021 study found that drinking more than six drinks per week during the luteal phase, the time after ovulation when the body prepares for implantation, reduced conception odds by 50%. Drinking between three and six drinks per week in this phase lowered fertility by 44%, showing that this stage is sensitive to alcohol.

The effect was stronger during ovulation. Drinking heavily in this phase reduced conception odds by 61%, likely because alcohol interferes with hormone levels and egg quality. Binge drinking during the ovulatory phase had the strongest impact, lowering fecundability (the probability of conceiving in a single menstrual cycle) by 41% per additional day of excessive alcohol intake.

Regardless of how much you drink, alcohol disrupts key reproductive hormones and makes conception harder. Beyond fertility, alcohol’s impact on overall health increases the risks of liver disease, breast cancer, heart failure, and mental health struggles.

How long after quitting drinking does fertility restore?

Your body starts repairing itself the moment you stop drinking. In men, sperm quality improves within three months, the time needed for a full sperm regeneration cycle. Women may see hormone levels stabilize in one to three cycles, depending on their previous levels of alcohol consumption.

For heavy drinkers, full recovery can take six months or more. Cutting alcohol is one of the most effective lifestyle factors to improve fertility. If you’re trying to conceive, quitting now can boost your chances significantly—your body and future baby will thank you.

Alcohol and infertility FAQ

What is the 20-minute rule for alcohol?

The 20-minute rule for alcohol highlights the time it takes for alcohol to begin affecting the body after consumption. Once an alcoholic drink is ingested, it takes about 20 minutes for it to enter the bloodstream and alter blood alcohol concentrations, impacting coordination, judgment, and decision-making. This delay can lead to excessive alcohol consumption before the effects are fully felt, increasing health risks such as impaired endocrine function, disruptions to fertility hormones, and long-term negative effects of alcohol on reproductive health.

Practicing the 20-minute rule by pacing drinks and waiting before consuming more can prevent binge drinking, reduce overall weekly alcohol intake, and support better reproductive outcomes for men and women.

Does alcohol affect female hormones?

Alcohol alters female hormones, affecting ovulation, menstrual cycles, and egg quality. It disrupts follicle-stimulating hormones, leading to ovulatory dysfunction and increasing infertility. Excessive drinking raises estrogen levels, which can contribute to ovulatory disorders, polycystic ovary syndrome (PCOS), and hormonal imbalances that make conception difficult.

Alcohol-induced hormonal shifts can also interfere with pregnancy maintenance, increasing the risk of spontaneous abortions and low birth weight. Women looking to conceive should avoid alcohol to support healthy reproductive function.

Do men need to stop drinking when trying to conceive?

Men should limit or eliminate alcohol when trying to conceive. Paternal alcohol consumption affects sperm concentrations, increasing the risk of genetic abnormalities and reduced fecundability. Excessive alcohol consumption causes oxidative damage to sperm DNA, increasing the risk of birth defects and early pregnancy loss. Even moderate alcohol intake is linked to lower testosterone and hormonal imbalances, which reduce fertility. Men who quit alcohol before conception had higher sperm quality and better reproductive outcomes.

Is one drink a day bad for you?

Even one drink per day can have long-term consequences, particularly for pregnant women, those trying to conceive, or individuals at risk for alcohol use disorder. Even moderate alcohol intake affects fertility hormones, increasing the risk of ovulatory dysfunction in women and lowering sperm concentrations in men.

Previous studies indicate that regular alcohol intake can contribute to endocrine function disruptions, increasing the risk of female infertility and affecting birth weight in pregnancies. While occasional consumption may not seem harmful, drinking daily increases the risk of harm, particularly to reproductive organs and overall reproductive outcomes.

Can alcohol-induced infertility be reversed?

Alcohol-induced infertility is often reversible. Sperm concentrations, female fertility, and ovulatory function can recover within months after stopping alcohol. However, the timeline depends on levels of alcohol consumption and the extent of damage. Excessive alcohol consumption leads to hormonal imbalances, affecting follicle-stimulating hormone and sperm production in men while disrupting ovulatory cycles in women.

Quitting alcohol restores endocrine function, improves reproductive outcomes, and helps return the body to a healthy weight, a crucial factor in natural fertility. For those struggling with alcohol use disorder, professional treatment can significantly increase fertility restoration and overall health.

Can alcohol affect egg quality?

Alcohol consumption negatively impacts egg quality, leading to female infertility and an increased risk of spontaneous abortions. Excessive drinking disrupts follicle-stimulating hormone levels, which are essential for ovulation and egg development.

A systematic review and meta-analysis found that alcohol per week affects ovarian reserve, reducing the number of viable eggs and increasing premature births. The effects of alcohol consumption also extend to the uterine environment, making it harder for a fertilized egg to implant successfully. Reducing or eliminating alcohol intake improves egg quality, supporting healthy lifestyle choices that enhance reproductive outcomes.

Can alcohol affect early pregnancy?

Alcohol can severely affect early pregnancy, increasing the risk of fetal alcohol syndrome, low birth weight, and spontaneous abortions. Since many women do not know they are pregnant in the first few weeks, alcohol can unknowingly disrupt fetal development before pregnancy is confirmed. Excessive consumption of alcohol interferes with placental function, restricting oxygen and nutrients to the developing embryo. Even moderate alcohol intake during this time increases the risk of adverse effects, including fetal alcohol spectrum disorder. To avoid complications, women trying to conceive or in early pregnancy should eliminate alcohol.
