Alcohol And Sperm Health — Does It Matter?

It is a no-brainer that mothers need to avoid alcohol before and during pregnancy because drinking causes significant developmental defects and low birth weight. However, anyone hardly talks about the alcohol consumption of an expectant father.

This notion may be less popular because the baby is not directly affected by alcohol levels of the father’s blood, but it does matter. Alcohol and sperm health are interlinked, and future fathers need to be mindful of their alcohol intake during preconception periods.

This article explains the effects of alcohol on male reproductive health and sperm parameters.

How Does Alcohol Affect Sperm Health?

Alcohol and sperm health has been studied extensively. The myriad of research papers provides substantial evidence for detrimental sperm parameters.

#1 It Diminishes Sperm Production

Sperm production occurs through the division of male germ cells called spermatids. These are present in your testes since birth and go through spermatogenesis to form sperm.

Increased blood alcohol levels diminish sperm production by destroying these spermatids. As a result, your sperm count decreases.

#2 It Reduces Sperm Motility

Alcohol increases the liquefaction time of semen after ejaculation — this is the time semen takes to dry up in the female reproductive tract.

You may interpret it as a good thing, but science shows that it reduces sperm motility. Those who engage in excessive alcohol drinking have slow sperm with non-progressive motility.

#3 It Damages DNA in Sperm Cells

Alcohol causes significant DNA damage in sperm cells because it produces toxic chemicals in the body, which destroy DNA structure.

Alcohol also deteriorates your vitamin B12 level, an essential constituent of the building blocks of DNA. Deficient or incapable chromatin material makes fertilization impossible or results in loss of pregnancy.

#4 It Destroys Normal Structure Of Sperm Cells

Alcohol consumption has the most prominent effect on the structure of spermatozoa. Men who drink have a remarkably higher proportion of sperm with structural abnormalities.

Scientists have observed curling of tail around the sperm cell, elongation of midpiece, or damage to the head of sperm cells. These defective cells cannot swim or achieve fertilization.

This low percentage is apparent in semen analysis of men and often becomes the most common cause of male infertility in alcoholics.

#5 It Decreases Semen Volume

Alcohol reduces the performance of accessory glands in the body. These glands do not take part in sperm production but form semen. Their malfunction diminishes semen production, and the volume of your ejaculate goes down.

They also need nutrients to secrete semen that can promote sperm health. For instance, your sperm cells need zinc for DNA protection, which is present in semen. Alcohol intake deteriorates these nutrients from the body and produces inadequately protective semen.

Does Alcohol Impact Male Reproductive Tract?

The influence of alcoholic beverages is not limited to your semen parameters only, it also extends to your reproductive tract. The ethanol in alcohol suppresses your immune system and makes you more prone to infections.

If your alcohol consumption is higher, you can get urethritis — an infection of the urethra. It may even increase the severity of sexually transmitted diseases. These infections are capable of impairing sperm formation and transport to the vagina. Similarly, prostatitis affects the prostate gland and lessens the production of semen.

Apart from these, alcohol tends to throw off the hormonal balance of the body. It decreases your testosterone levels, and since testosterone is responsible for sperm health and production, it may set the stage for male infertility.

How long after quitting drinking will sperm improve?

The good news is that alcohol and sperm health have a reversible relationship. If you stop drinking, your sperm health improves with time. According to research, it takes roughly three months for your sperm production to regain normality after quitting.

Unfortunately, liver damage associated with alcoholics who have a remarkably long history of alcohol intake may make the regaining of sperm health harder.

How Much Booze Is Too Much For Male Fertility?

There is a grey area regarding the quantity of alcohol you can consume. Moderate intake is safe, but binge-drinking and prolonged alcohol intake daily can be detrimental. Some data suggest that moderate intake for a short duration may even raise your testosterone levels.

However, even with moderate drinking,sperm count takes a hit. It may not make you infertile but lessens your potential in comparison. Heavy drinking changes testes more noticeably. For instance, heavy drinkers may experience shrinkage of testes and infertility.

So, the take-home points are:

  • Even if you are a moderate drinker, your sperm count may be lower than those who do not consume alcohol.
