Although alcohol consumption is relatively common and socially accepted, there is growing awareness of its negative effects on human health. What may be less known is how continuous alcohol intake can affect fertility in both men and women. This impact can be even more significant when undergoing fertility treatments.
Alcohol can cause many side effects for the body that may endanger overall health. However, what few people realize is that it also affects fertility. In women, for example, alcohol consumption can disrupt hormonal balance, which is essential for ovulation. Indeed, even moderate consumption—defined as one or fewer drinks per day—can affect ovarian function and even interfere with embryo implantation, thereby reducing the probability of achieving pregnancy.
Moreover, alcohol is associated with a higher risk of menstrual disorders such as irregular cycles or anovulation. It is also important to note that during early pregnancy (before the woman knows she is pregnant), alcohol can increase the risk of miscarriage.
Primarily, it can affect semen quality by reducing sperm concentration, motility (movement), and morphology (shape). It may also impact testosterone levels, which are essential for sperm production and may decrease with alcohol consumption.
Furthermore, excessive consumption (more than 3-4 drinks daily or binge drinking) can cause oxidative stress in the testes, which can damage sperm DNA. Therefore, not only does it reduce the chances of achieving pregnancy, but it may also affect embryo development.
Sperm seen under a microscope
It is highly recommended to avoid alcohol completely both before and during assisted reproduction treatments. Generally, the need to undergo reproductive medicine arises because there is already a problem conceiving (except in the case of single mothers or same-sex couples), so consuming alcohol will not help improve the situation; quite the opposite.
Therefore, although an occasional drink may seem harmless, experts agree that the safest course is to eliminate alcohol entirely during the process.
The advice remains the same. Many people believe that very occasional drinking does not affect the body, but the general recommendation by specialists is very clear: during the pregnancy seeking phase, especially when difficulties exist, it is best to opt for abstinence or, if not possible, to reduce alcohol consumption as much as possible.

In most cases, yes. The negative effects of alcohol on fertility typically reverse once consumption stops. In women, ovulation can improve after a few weeks of abstinence, and menstrual regularity is restored. In men, seminal parameters may take two to three months to improve, as this is the time it takes the body to produce a new generation of sperm.
