How Does Alcohol Affect Sperm?
Contents
Excessive alcohol consumption has been shown to drastically reduce testosterone production and even shrink the testicles, where testosterone is produced in men. Research suggests exercise may help improve male infertility, especially when it’s linked to factors like obesity and diabetes. One study showed exercise helped improve sperm production and quality in people with lifestyle-related infertility .
A myriad of studies are showing biological fathers who drink alcohol may have a significant role in causing health problems in their children. Abstaining from alcohol during preconception and pregnancy is usually considered to be the woman’s responsibility. The main concern surrounding alcohol exposure during pregnancy often relates to well-established evidence of newborns developing a range community fairbanks recovery center of behavioural, physical and cognitive disabilities later in life.

It does this by directly impacting all three areas of the male reproductive system and the hormones they make. Having the occasional alcoholic drink is unlikely to significantly affect your fertility. But research does suggest that regular how to beat alcoholism as a midlife adult alcohol consumption may lower your semen parameters. Acute treatments with cannabinoids can decrease the fertilising capacity of sea urchin sperm . In rodent studies, high THC doses caused a modest increase in abnormally formed sperm.

Alcohol is known to disrupt circadian rhythms
The participants also provided semen and blood samples so researchers could look at their sperm quality and reproductive hormones. There is conflicting data regarding the effects of alcohol exposure in utero when there is no evidence for FASD. It’s important to remember that it isn’t just female fertility that is affected by alcohol – and male partners must also take responsibility.

Among this group of men, researchers found that the higher the tally of weekly units, the lower was the sperm quality in terms of sperm count and the proportion of sperm that were of normal size and shape. The effects were evident in those who drank five or more units a week and most apparent in those who drank 25 units or more. Those who typically drank 40 units a week had 33% lower sperm count and also had 51% less “normal looking” sperm than men who drank between one and five units a week. A recent study of 1,221 young Danish men (18-28 years of age) tracked alcohol consumption in the week preceding the study to determine its effects on semen quality . In another experimental study, sperm health and fertility was assessed in male rats after administration of alcohol into the stomach for ten weeks.
A study on adult male mice showed regressive changes in the testes and suppressed sperm count, viability and motility, caused by chronic intake of bhang. High alcohol consumption and heavy smoking can cause lower testosterone level and alter sexual function. Studies have found that one major factor that contributes to male infertility is heavy alcohol consumption. Heavy drinking is considered more than five drinks within a two hour period for men or more than 15 mixed drinks in a week. However, it’s important to note that low to moderate alcohol consumption – up to two drinks in one sitting – does not have a negative effect on male fertility. Sertoli cells produce a protein that nurtures sperm and helps them develop normally.
This means changes to gene expression occur without changes to the underlying DNA sequence. These epigenetic marks can be transferred at the time of fertilisation. This can subsequently alter the molecular makeup of the early embryo, leading to alterations in foetal development and the potential to impair offspring health. Animal studies have shown a single dose of ethanol into the stomach lining induces damage to the testis, damaging the cells essential for sperm formation. But recent research is also pointing to a link between alcohol and poor sperm development, meaning the onus is on expectant fathers too.
After considering certain influential factors, the researchers found that there was no significant link between sperm quality and alcohol consumption or binge drinking in the preceding month. After coming home from a stressful day at work, cracking open a fresh, cold beer to relax can be tempting. But a new study published in BMJ Open suggests that even a moderate weekly alcohol intake of five units is linked to lower sperm quality in men who are otherwise healthy. By interfering with how the reproductive system functions, alcohol use can significantly impact both a male’s sperm production and his hormones. This, in turn, can reduce fertility and make it more difficult for a couple to become pregnant. Drinking alcohol – even in moderation – can have a dramatic effect on the reproductive system.

The mechanisms underlying the damage of alcohol on fertility are not yet fully clarified. Close and colleagues reported that current heavy alcohol users have significantly higher leukocyte concentrations in the seminal fluid compared with nonusers. After controlling for past sexually transmitted diseases and multiple substance exposures in a multivariate model, alcohol users had only a trend towards increased leukocytes in the seminal fluid . Some Authors hypothesized that also maternal alcohol consumption during pregnancy can influence semen quality in the male offspring. From a cohort of Danish pregnant women established in 1984–1987, 347 young adult sons were selected for a follow-up study conducted in 2005–2006.
- Moreover, recent animal and human studies show exposure to alcohol during early development and later in life leads to changes in the DNA.

- The etiology for the detrimental effects on IVF outcomes has not been identified.
More recently, a meta-analysis study on a grand total of 5865 subjects has concluded that moderate and heavy smokers are more likely to have reduced sperm count and motility . Evidence suggests a significant role for cigarette smoking on spermatogenesis, but on the other hand the impact of smoking on male fertility has yet to be fully elucidated. A preventive approach to infertility, suggesting smoking cessation and reduction of second-hand smoking in both women and men, should be suggested. Conversely, moderate alcohol intake, defined as up to 1 drink per day for women and up to 2 drinks per day for men, may offer some health benefits . These benefits include decreased risk of stroke and diabetes, as well as decreased risk of heart disease or mortality from heart disease. In 2005, it was estimated that 26,000 deaths were prevented in the U.S. due to reductions in ischemic heart disease, diabetes and ischemic stroke because of benefits attributed to moderate alcohol consumption .
Alcohol’s Effect on Testosterone Production
A lower sperm count and distorted sperm are the results of alcohol abuse. Men who regularly participate in heavy drinking are at risk for a number of fertility-related side effects, including low libido and reduced sperm count. A heavy drinker may also experience sexual dysfunction as a result of what is a halfway house alcohol. Seeking treatment at a rehab facility such as the Vertava Health treatment centers can help men reclaim their lives in sobriety and improve overall health and wellness. Besides its impact on sperm quality, alcohol can also lead to erection issues or alcohol-induced erectile dysfunction .
Chances are you will also have been recommended to stop drinking alcohol. But how are alcohol and fertility linked, and can drinking impair your chances of conceiving? However, new research has now indicated that both the timing in your cycle at which alcohol is consumed and the quantity one drinks will play a role in this effect.
However, lowering alcohol consumption or quitting drinking can drastically improve fertility in men who experienced fertility problems as a result of drinking. In fact, some studies have shown a significant improvement in sperm after 90 days of abstinence. Heavy alcohol consumption can directly affect the reproductive system of a male as well as his hormones. Alcohol use impacts a male’s hypothalamus-pituitary-gonadal axis or HPG axis.
More than 14 mixed drinks in a week can lower testosterone levels and affect sperm count. The good news is that, if you reduce your drinking, your sperm are likely to recover and reverse the adverse effects of alcohol on male fertility. The sperm cycle is around 74 days, so you should expect to see an improvement in any alcohol-related fertility concerns after about three months of drinking less. A recently published study by the University of Louisville, Kentucky reviewed data from 413 participants who reported their daily alcohol intake for up to 19 months, specifying both the number and type of drink. The researchers classified an alcoholic drink as 335ml of beer , 148ml of wine or 44ml of spirits . This was the first study of its kind to investigate this according to the different phases of the menstrual cycle.
Some men who use alcohol may have no sperm in their semen, making it impossible for pregnancy to occur naturally. There are several different ways in which a male’s fertility may be affected by alcohol use. One way is by lowering a man’s libido, making it harder to perform or want to perform sexually. Decreased libido can lead to decreased sex, which can make it more difficult to become pregnant.
Does drinking alcohol affect sperm?
A study of 1221 men in Denmark found that sperm quality decreased in men who reported drinking more than 5 units of alcohol a week. This decrease in sperm quality became even more pronounced in men who reported drinking over 25 units of alcohol in a typical week. Wenger and colleagues showed that THC alters pituitary LH release by inhibiting the release of LHRH, injecting THC into the third cerebral ventricle of male rats . Smith et al. found a significant decrease in serum testosterone concentration following acute doses of THC in rhesus monkeys.
