Abstract – The male reproductive system consists of the hypothalamus, the anterior pituitary gland, and the testes. Alcohol can interfere with the function of each of these components, thereby causing impotence, infertility, and reduced male secondary sexual characteristics.
In the testes, alcohol can adversely affect the Leydig cells, which produce and secrete the hormone testosterone. Studies found that heavy alcohol consumption results in reduced testosterone levels in the blood. Alcohol also impairs the function of the testicular Sertoli cells that play an important role in sperm maturation.
In the pituitary gland, alcohol can decrease the production, release, and/or activity of two hormones with critical reproductive functions, luteinizing hormone and follicle-stimulating hormone. Finally, alcohol can interfere with hormone production in the hypothalamus.
Keywords: AODE (alcohol and other drug effects), hypothalamus, pituitary gland, male genitals, reproductive function, testosterone, hormone metabolism, heavy AOD use, cell type, luteinizing hormone, follicle stimulating hormone, gonadotropin RH, secretion, animal model, male, literature review In both men and women, the hormones regulating reproduction form a complex and finely tuned system that affects virtually every cell system in the body.
The male reproductive system consists of three parts: a brain region called the hypothalamus, the anterior pituitary (a gland that is located at the base of the brain but is not considered a brain region), and the testes. This article briefly reviews how those three organs and the hormones they produce cooperate to ensure and regulate male reproductive functioning.
How much alcohol lowers testosterone?
The Direct Effect of Alcohol on Your Testosterone – First, studies continue to show that heavy doses of alcohol directly cause a decrease in testosterone production in men. In a review of the available research, scientists concluded that a 160-pound man would need to drink 5 or 6 glasses of beer that contains between 4.5 and 6 percent alcohol per 12-ounce glass in order to cause a direct decrease in serum testosterone levels.
- That’s still an approximation, but it supports what we’ve known for decades: Ethanol alcohol is a testicular toxin, and these large doses reduce testosterone function, sperm count, fertility, and can even cause permanent damage to the testes.
- Alcoholic men are known to suffer higher rates of infertility and extremely low testosterone levels.
An important side note is that no differences between adolescents and adults were identified, which means binge drinking among younger males likely has harmful effects on their hormone balance—possibly resulting in Low T symptoms despite their relatively young age.
Will testosterone increase after quitting drinking?
Will quitting alcohol increase testosterone? Testosterone levels have been shown to increase after several weeks of sobriety.
Does alcohol affect taking testosterone?
– People with a history of alcohol misuse are at a heightened risk for developing low testosterone. Continuing to drink heavily while undergoing testosterone replacement therapy may undermine the treatment’s effectiveness. Many doctors recommend limiting or quitting alcohol while taking testosterone.
What lowers your testosterone level?
If you’re concerned about low testosterone levels, take a look at your everyday habits and way of life. They could be contributing to a drop. Your doctor can order a blood test to check your testosterone levels if you suspect they’re low. Testosterone levels are usually related to age and physical fitness, according to Ghandi Saadeh, MD, an internal medicine and endocrinology specialist with Sentara Medical Group in Kempsville, Virginia.
- But your doctor will probably also ask about your lifestyle to find out what else might be going on.
- Here are a few ways you may be lowering your testosterone levels without knowing it: 1.
- Being overweight.
- Waist size has a much bigger impact on testosterone than aging,” says endocrinologist Frances Hayes, MD, an assistant professor of medicine at Harvard Medical School in Boston.
“We can’t slow aging, but we can prevent weight gain.” Excess weight can keep testosterone levels low, according to the Society for Endocrinology. Obese and overweight men see the greatest improvement in their testosterone levels if they lose weight with a combination of exercise and a restricted-calorie diet, according to research in the July 2014 Journal of Diabetes and Obesity,
Aim to lose at least 15 percent of your weight — an amount that triggers a significant rise in testosterone, according to the results of the European Male Aging Study, which followed more than 2,000 men aged 40 and older for about four years. The results were published in the February 2013 European Journal of Endocrinology,2.
Sitting around. Being physically inactive could also lower your testosterone. When researchers had 30 sedentary young men participate in a 12-week exercise program, they found that the participants’ testosterone levels increased, according to a study in the April-June 2014 Indian Journal of Physiology and Pharmacology,
- In addition to weight loss, with exercise “men may note improvements in testosterone, bone density, memory, fertility, heart and sexual health, as well as mood,” says Ryan P.
- Smith, MD, a urologist with the University of Virginia Health System in Charlottesville, Virginia.3.
- Using narcotic pain medications.
“Continuous use of narcotic painkillers can cause low testosterone,” says Dr. Saadeh. A review article in the May-June 2015 Journal of Opioid Management found a strong link between long-term use of narcotic pain medications and hypogonadism, but cautioned that researchers do not yet know whether there’s a link between chronic pain management and low testosterone.
Talk with your doctor about how to stop using these medications, Saadeh advises. RELATED: 6 Best Foods for Men’s Health 4. Using anabolic steroids. “Use of anabolic steroids for bodybuilding will cause the testes to shut down their testosterone production,” Saadeh says. “This could be permanent, even after discontinuation of these drugs.” When researchers compared weight lifters who used anabolic-androgenic steroids with weight lifters who did not use them, they found an increased risk for low testosterone even after the weight lifters stopped using steroids, according to research in the May 2015 journal Addiction,
Make sure you let your doctor know if you’re now using, or have ever used, steroids for bodybuilding.5. Using hair-loss medications. “Certain hair-loss medications, such as Propecia ( finasteride ), block the conversion of testosterone into other active metabolites and can cause low libido and sexual function,” Saadeh says.
Some people experience persistent symptoms like sexual dysfunction and depression after using finasteride, possibly because of the medication’s effect on testosterone and other hormones in the body, according to February 2015 research in The Journal of Steroid Biochemistry & Molecular Biology,6. Not getting enough sleep.
“Sleep disruption does tend to lower testosterone, and there is a link between obstructive sleep apnea,” Dr. Hayes says. A review of research underscores the complicated relationship among excess weight, sleep disturbance, and low testosterone, and examines the recommendation that men both lose weight and use a CPAP machine to correct sleep apnea,
Does beer boost testosterone?
Can you really build muscle and drink beer? “Milk is for babies. When you grow up you have to drink beer.” Or so Arnie would have you believe. By contrast, today’s gym bros swear by GOMAD (gallon of milk a day) and feel pangs of guilt just looking at a pint.
But is beer really on the banned list? The nutritional know-it-alls at have the answer. To answer this question, let’s first consider the markers researchers can measure. When we exercise, our muscles get damaged and depleted of oxygen, sending a multitude of signals throughout the body. Over the next day or two, our muscles react by repairing the damage, becoming stronger and bigger.
One way this response can be measured is by looking at the rate of muscle protein synthesis. The other notable marker is the anabolic hormone: testosterone. As for the third marker, performance, it’s the least liked by scientists, who find it hard to pour into a beaker—which is to say, it’s hard to measure accurately.
- The Science Behind Your Post-Workout Beer The most relevant human study observed that heavy drinking post-exercise (about 7 beers for a 150-pound person) suppressed muscle protein synthesis.
- This suppressive effect, which occurred even when the alcohol was consumed after 25 grams of protein.
- Showing even protein’s anabolic effect can’t overcome heavy drinking.
The current evidence indicates that heavy drinking impairs workout recovery and muscle growth; but what about a single beer after exercise? While quality studies on the topic are lacking, what limited evidence is available suggests that a couple of drinks won’t undo your hard work at the gym.
- Alcohol and Testosterone Testosterone is the primary male sex hormone; the more you have, the easier (and faster) it is to build muscle mass.
- So, does beer affect testosterone levels? Yes, both positively and negatively.
- An increase in circulating testosterone, of about 17%, has been seen in both young men who drank a little (about 2 beers for a 150-pound person).
However, such a small boost—more variation is seen from day to day or even within the same day—is unlikely to help boost your muscle growth. On the other hand, heavy drinking (the aforementioned 7 beers for a 150-pound person) has been found to suppress testosterone.
Furthermore, even moderate amounts of alcohol (3 or 4 beers) have been shown to mildly suppress testosterone when ingested daily for at least three weeks. And that could be enough to undo some of your hard work in the weight room. A Bitter Hop(e) One recent study found that isohumulones, the main compounds responsible for the bitter taste we attribute to hops, might support weight loss.
This study only investigated the fat-burning potential of isolated isohumulones, however, not of beer as a whole, so don’t start downing pints in the hope of shedding pounds—especially since the calories in alcohol can quickly add up! Yet, after this study, one cannot help speculating that IPAs, with their high hop content, might have a slight advantage over other beers.
The Big Picture Right now the evidence suggests that if beer has an effect, good or bad, this effect is very small—subtle enough that if a perfect pint of your favorite beer is your favourite way to unwind after a hard workout, then you can drink guilt-free. Unless you start soaking your clothes in it or have a habit of binge drinking, one beer isn’t likely to hurt, or help, your workout.

Does one beer a day affect testosterone?
Alcohol can affect fertility, sexual performance and sexual health – Alcohol depresses the central nervous system which can make it difficult for some men to get, and keep, an erection.1 Importantly, alcohol alters the chemicals in our brains, including the part associated with inhibition.2 So men are far more likely to act in an uninhibited way when they have been drinking.
Which alcohol increase testosterone?
Does Drinking Red Wine Boost Your Testosterone Levels? 
If you know you need to boost your testosterone levels and have been researching ways to do so online, you may have come across articles or blogs claiming that red wine can help you get your testosterone levels up. While the answer is true – red wine has been proven in studies to help you excrete more testosterone – it does come with a caveat, which we’ll explain later in this post.
Can smoking lower testosterone?
The results of previous studies describing the effects of cigarette smoking on testosterone levels in human males have been conflicting, demonstrating that testosterone levels are lower, similar or higher in healthy male smokers than in matched non-smokers.
Do bananas lower testosterone?
Do bananas lower testosterone? – Nope, they raise it. We’re not sure why bananas get this “bad for your testosterone” vibe. They may not be protein- or healthy fat-dense enough to warrant being their own meal, but they don’t kill your sex drive or break down your muscle mass.
Quite the opposite. Bananas’ chief nutrient, potassium ( 23 ), actually promotes testosterone production and firmer erections. The fruit also contains bromelain ( 24 ), a slow-releasing enzyme that can increase your libido; tryptophan,( 25 ) which boosts the secretion of serotonin, a hormone that can improve your mood, brain function, and sex drive; and vitamin C ( 26 ), which helps keep cortisol, aka the “stress hormone,” at bay.
And researchers say to let ’em ripen ( 27 ) if you want bananas’ nutrient levels to rise.
Do eggs lower testosterone?
Eggs – Eggs are a fantastic source of protein, cholesterol, vitamin D and omega-3s, all of which aid in the production of testosterone. Eggs are a very versatile ingredients and not only do they help increase testosterone levels, the protein in them helps with muscle building too!
Does Coca Cola increase testosterone?
DISCUSSION – Currently, carbonated beverages (CBs), are daily consumed by many people worldwide ( 3, 19 ). CBs have been a deleterious key factor along with their consumption increase. The overweight, obesity, diabetes and endocrine disorders are associated with massive consumption of CBs ( 2, 20 ). CBs harmfully affect reproduction functions ( 21, 22 ). A survey of 2500 men indicated that the sperms quantity was reduced by 30% after men drank 1 liter cola beverage every day as compared to those without drinking any CSD. The oxidants and additives in CBs result in proteins oxidation, cell damages ( 15 ) and reduce sperm motility ( 23 ). In our study, we found that testes masses of PEP-2, COC-1 and COC-2 groups were increased in comparison with PEP-1 and CG (P<0.05) on day 15. The testes longitudinal and transverse diameters become larger as compared to CG. Our initial experiments demonstrated that Pepsi-Cola and Coca-Cola could reduce ovarian weight, inhibited the development of follicles and oocytes. Pepsi-Cola and Coca-Cola obviously reduced pregnancy rate and fetus numbers of female mice, such affected reproduction behaviors of female mice ( 11 ). Our results revealed serum EGF contents of COC-2 and PEP-2 were higher than that of CG. These findings demonstrated high doses of Coca-Cola and Pepsi-Cola could enhance EGF activity and testosterone secretion. These are in agreement with our previous study in rabbits ( 12 ). However, the effects have to be deeply studied. Its mechanisms also have to be further explained in other mammals in the future ( 5 ). Androgen and its receptor (AR) affect the development of normal prostate and prostate cancer ( 24 ). In the present study, we investigated the effects of Coca-Cola and Pepsi-Cola on androgen receptor (AR) expression levels in the mouse testes. The findings indicated AR mRNA and protein levels of the CBs-treated mice were strikingly increased when compared to CG normal level. Nowadays, scarce document is reported on this subject ( 25 ). Such, these findings still need to be validated in the future ( 18 ). In conclusion, drinking Coca-Cola and Pepsi-Cola could promote testis development, enhance testosterone secretion, increase serum EGF concentrations, also accelerated expressions of AR protein in the mice testes. Our findings provided the scientific bases and for fully understanding CBs effects and their mechanism on development and reproduction functions of humans, but also benefit to prevent prostate dysfunction and cancer.
Why is alcohol bad for bodybuilding?
Does Drinking Alcohol Limit Muscle Growth Potential? – As a fitness professional you know,
1 gram of carb contains 4 calories, 1 gram of protein contains 4 calories, and 1 gram of fat contains 9 calories.
Alcohol is quite different as it does not contain any macronutrients or micronutrients. But it has 7 calories per 1 gram of alcohol. If you have ever heard that alcohol is empty calories, this is why. So, what actually makes alcohol detrimental to your health? Many assume that because they have a good diet, alcohol will not affect their body.
Unfortunately, this is not true. Having a good nutrition plan does not outweigh the negative effects of alcohol. To achieve results in the gym, you need a combination of exercise, nutrition, and recovery. Alcohol interferes with this process no matter how strict you are with the foods you eat. The main reason for this is that alcohol impairs myofibrillar protein synthesis (MPS).
Protein synthesis occurs to repair muscle protein. When you exercise, muscles undergo stress and become damaged. To repair this damage, muscles need protein. MPS is the process that promotes protein turnover. Alcohol contributes to protein breakdown more than your nutrition does to protein synthesis.
When the body degrades muscle protein, it breaks down more muscle than it builds. In other words, never building muscle. Many try combining protein sources with alcohol to outweigh the negative effects. This does not diminish the effects of alcohol on muscle growth. But to help limit the severity of negative effects, you can work out earlier in the day.
Leave as much time in between workouts and consumption of alcohol as you can. This limits the effect it has on muscle protein synthesis.
Does red Bull lower testosterone?
Background – Caffeine is one of the most commonly used psychoactive drugs in the world, and provides many health benefits including alertness, improved memory, and reducing inflammation. Despite these benefits, caffeine has been implicated in a number of adverse health outcomes possibly due to effects within the endocrine system, effects that may contribute to impaired reproductive function and low testosterone in men.
Will one beer ruin my gains?
The Big Picture – Beer lovers, rest easy. Though more research is needed, there is currently no evidence to suggest a post-workout beer or two can cause long-term harm. If a tall one is your go-to treat after a hard workout, you don’t need to worry about your testosterone levels or protein synthesis rates.
Does wine lower testosterone?
Don’t Build a Wine Cellar Just Yet – While wine aficionados may love to hear this news, it isn’t a reason to start stocking up on your favorite merlot. Alcohol consumption in general – whether it be wine, beer, or spirits – is known to decrease a person’s overall testosterone levels.
What alcohol is best for high testosterone?
Don’t Miss A Drop – Get the latest in beer, wine, and cocktail culture sent straight to your inbox. And while all alcohol in moderation helps a bit when it comes to sexual pleasure and desire, none has more benefits than red wine, both for males and females.
For the ladies, red wine causes the sex drive to be even more pronounced than with other drinks, at least according to a group of Italian researchers who discovered that the compounds in the wine actually enhance levels of sexual desire in the fairer sex. What the researchers uncovered was that the red wine specifically increased blood flow to women’s erogenous areas, which in turn led to increased levels of desire.
The researchers were quick to point out, however, that after more than a drink or two the other effects of alcohol began to take hold, which led to a less pleasurable experience. Moderation, it seems, is key. For men, not only does a drink or two loosen things up and increase blood flow to essential areas, but red wine also seems to increase levels of testosterone in the blood, a necessary hormone when it comes to male sexual arousal and “appetite.” Normally a male’s body rids itself of testosterone when an enzyme called UGT2B17 attaches specific molecules to testosterone, enabling the body to identify it and get rid of it through the urine.
- But when consuming a glass of red, a compound inside the wine called quercetin effectively blocks UGT2B17, preventing the body from excreting it, and thereby raising levels of testosterone in the blood.
- However, just as with women, a few too many drinks and all alcohol, including red wine, can have the reverse effect, lowering testosterone and decreasing the sex drive.
So when it comes to alcohol and sex, the best prescription is opening and splitting a bottle of red with your partner. It’s the perfect amount for you to each have two glasses and experience the positive effects the combination of wine and sex can deliver, with a smaller chance of the negatives.
