Alcohol and Low Testosterone: Excessive Drinking Can Lower Testosterone

Interestingly in 100% of analysed studies, an ethanol dose administration greater than 1.5 g/kg showed a decrease in testosterone serum levels. Incubation of myocytes for 72 hr decreased synthesis in cells incubated with ethanol ranging between 60 and 120 mM. The ability of IGF-I or insulin to stimulate protein synthesis was impaired by 30% and 60%, respectively, in cells incubated with 80 mM of ethanol for 72 hr.

For instance, in an older study of healthy, premenopausal females, participants were given between 0–4 alcoholic drinks per day . Rather than lowering their testosterone levels, the alcohol caused significantly higher levels of testosterone in the study’s female participants. 30 minutes – In one study, healthy male participants showed a decrease in testosterone levels within 30 minutes of a heavy dose of alcohol . Researchers found that after the participants stopped drinking, their testosterone levels quickly returned to normal. However, this doesn’t necessarily mean that continuing to heavily consume won’t have an effect.

What’s in a drink? Moderate vs. heavy drinking

Furthermore, ethanol consumption may suppress protein synthesis slightly via inhibition of exercise-induced mTOR, which is partially dependent on phosphatidic acid from the cell membrane for complex stabilization . Ethanol is used as preferential substrate by the enzyme Phospholipase D and phosphatidylethanol is produced in lieu of PA, which causes an indirect suppression of mTOR . It appears to act more on the mTORc1 subcomponent, as higher concentrations are needed to inhibit the mTORc2 component . This mechanism of action has been demonstrated acutely with mouse myocytes and chronic alcoholism adversely affects mTOR and S6K1 phosphorylation .

alcohol and testosterone

Before we can discuss how red wine boosts your testosterone, we need to first explain how your body eliminates this hormone. You see, your body has an enzyme called UGT2B17 which attaches to testosterone molecules, causing them to be eliminated from your body . Vermeulen et al. reported that free (i.e. bioavailable) testosterone reflects the clinical situation more precisely than the total hormone level or SHBG. Nevertheless, our study is the first to confirm this relationship in alcoholics.

However, the news might differ for men with liver damage related to drinking, like cirrhosis. Men with cirrhosis can have as much as a 90 percent drop in testosterone levels due to the disease. Your overall health as drinking is not the only thing that affects testosterone levels. Maybe you’ve been considering a vasectomy but haven’t quite finalized your decision yet because you’re worried about the side effects. Or maybe you’ve already been snipped and you’re wondering What if my vasectomy caused my decrease in low testosterone? Wherever you are on that journey to understanding the ins and outs of this simple and potentially reversible procedure, you should know that a vasectomy doesn’t impact your testosterone levels at all.

Continued, heavy consumption of alcohol can lead to elevated levels of the female sex hormone estrogen. When your body metabolizes alcohol, the amount of NAD+, a coenzyme responsible for testosterone production, decreases in the testes and liver. Chronic, excessive drinking can disrupt your sleep schedule, which decreases your body’s ability to produce testosterone. We cannot overstate the effects of alcohol on your bodily maintenance and functions. In the short-term, alcohol can impair judgment and motor abilities, such as coordination.

Because LH induces testosterone production, reduced LH secretion results in lowered testosterone levels. Some research findings suggest that testosterone also has a negative feedback function on GnRH. The hypothalamus releases gonadotropin-releasing hormone to the anterior pituitary gland, which in turn releases luteinizing hormone and follicle-stimulating hormone into the bloodstream. LH and FSH circulate to the testes, which release testosterone in response.

Overview of the Male Reproductive System

Moreover, 3-day treatment of alcohol-fed rats with IGF-I/IGFBP-3 reversed the increase in muscle myostatin mRNA. Constitutive expression of myostatin mRNA in muscle from control rats was relatively low. Although the basal and IGF-I-induced changes in myostatin mRNA are consistent with the observed changes in muscle protein mass determined in alcohol-fed rats . IGF-I resistance may represent a participating mechanism by which ethanol directly limits the translation of selected messenger RNAs and ultimately protein synthesis in skeletal muscle . Ethanol did not impair IGF-I receptor autophosphorylation, but inhibited the ability of insulin to phosphorylate its own receptor.

  • Gateway Foundation offers compassionate, effective treatment options for alcohol addiction.
  • Adopting an overall healthy lifestyle can help support your recovery.
  • And as your sleep schedule changes due to alcohol abuse, your body produces even less testosterone.
  • Heavy drinkers are more likely to have poor testicular function than people who consume a moderate amount of alcohol.
  • Myostatin controls cell cycle progression and inhibits skeletal myoblast proliferation and terminal differentiation.

It’s true that a healthy diet can impact your testosterone levels in that it keeps your body optimized to carry out various biological functions — and an increased BMI is often linked to low testosterone. But research into the effects soy has on testosterone levels are conflicting. To our knowledge, this is the first study investigating the course of plasma testosterone levels in alcohol dependent men over such eco sober house cost a long period. Additionally, there has been no study yet investigating the combined effects of alcohol and smoking on this hormone in alcoholics. Regularly knocking back too many shots of whiskey or glasses of merlot can interfere with hormone production in the hypothalamus. It can also directly impact the anterior pituitary gland’s ability to release LH and FSH, and damage the Leydig cells in your testes.

Hormone production is negatively impacted with poor sleep, so it is easy to see how alcohol consumption and poor sleep lead to low testosterone levels. In short, when you consume alcohol, your testosterone production isn’t going to be as high as when you aren’t drinking. Some men, are able to still maintain their normal testosterone levels while regularly consuming alcohol. However, if you are struggling with low T, one of the first things you should do is to completely eliminate alcohol, or cut back dramatically, and see if it impacts your T levels. Heavy drinking impacts the functioning of the Sertoli cells within the testes. These specialized cells are needed for sperm maturation, in which testosterone plays a huge role.

Pohl CR, Guilinger RA, Van Thiel DH. Inhibitory action of ethanol on luteinizing hormone secretion by rat anterior pituitary cells in culture. Scientists have attempted to identify the specific step in LH production and secretion that are impaired by alcohol. LH production is initiated by the interaction of GnRH released from the hypothalamus with specific docking molecules (i.e., receptors) on the surface of those pituitary cells that are involved in LH generation and secretion. Conceivably, alcohol could disrupt the functioning of the GnRH receptor or its interaction with GnRH, thereby leading to diminished LH release.

If you’re of the female sex, does that mean you’re out of the woods? Not necessarily—but the relationship between the body’s testosterone and alcohol may look a bit different. Whether you need to worry about alcohol intake affecting testosterone mostly depends on how much you drink and how often. For example, if you have one or two drinks a night, a few times a week, you probably don’t need to worry. But if you’re drinking alcohol heavily every day, it could affect testosterone levels over time. Excessive drinking also has a direct impact on Leydig cell function.

alcohol and testosterone

Numerous studies have indicated that alcohol abuse in men can cause impaired testosterone production and shrinkage of the testes (i.e., testicular atrophy) . Those changes can result in impotence, infertility, and reduced male secondary sexual characteristics (e.g., reduced facial and chest hair, breast enlargement, and a shift in fat deposition from the abdomen to the hip area). For example, in a classic study by Lloyd and Williams , 72 percent of men with advanced alcoholic cirrhosis exhibited decreased libido and sexual potency. Similarly, Van Thiel and colleagues noted that impotence was “prominent in the majority of subjects, but occurred more frequently among patients with greater liver damage” (p. 1190).

Alcohol’s Effects on the Hypothalamus

It took just one month for their testosterone levels to reach that of a chronic alcoholic. Contrary to popular belief, vasectomies and masturbation don’t lower testosterone. But smoking, drinking alcohol, testicular injury mash certified sober homes and pituitary/hypothalamus disruption do. Here are some truth behind popular myths about low testosterone levels. Alcohol addiction treatment is highly recommended to prevent symptoms such as loss of muscle and bone mass.

Does Alcohol Affect Testosterone?

Experimental studies also suggest that myocyte myostatin increases with ethanol exposure . Myostatin is the growth differentiation factor-8 (GF-1b), a potent inhibitor of skeletal muscle and heart growth . Myostatin controls cell cycle progression and inhibits skeletal myoblast proliferation and terminal differentiation. Its disruption causes increased skeletal mass with hypertrophy and hyperplasia of myocytes and increased myocyte proliferation . Al indicate that chronic alcohol feeding for 16 wk increases the myostatin mRNA content in the gastrocnemius.
