Effect of Ejaculation (Sex) on Bodybuilding Gains

September 30th, 2007 by Paul Johnson

The question on whether ejaculation (or sex) before workouts will effect their strength or muscle gains, is a common question for many bodybuilders. Athletes have also have been debating this question for years. Some believe that ejaculation before an athletic event will help their performance, while others believe it should be done after or even abstained completely. In this article I will discuss the hormonal effects of ejaculation on the body and when (or if) it should be avoided

Effects on testosterone during sexual arousal and ejaculation:

Testosterone level have been found in research to rise in humans after sexual stimuli (such as sexually explicit pictures). One study like this was published in New Scientist 22 Aug 98 11, done by Ludwig Boltzmann Institute for Urban Ethology in Vienna. 10 men and 10 women viewed a 15 minute pornographic film. Men’s testosterone levels increased 100 percent afterwards, while women’s was 80 percent.

Another study published by Psychoneuroendocrinology. 1993;18(3):205-18 used sexually arousing films on 9 males. LH levels (stimulates testosterone production) and testosterone levels increased within 10 minutes of sexually arousal. Other studies have also shown, other types of stimuli may also increase testosterone levels and agression, such as holding a gun.

Studies dealing with testosterone levels and it’s effects during sexual acts and ejaculation, seem to be mostly done on animals.  One study done on rats by the Instituto de Neuroetologia, Universidad Veracruzana, Xalapa, Ver., Mexico showed that after 2 ejaculations there was a steep rise in serum testosterone and remained higher even after 4 ejaculations in a row. Another study was done on stallions and mating by the Dipartimento di Scienze Cliniche Veterinarie, Sez. Clinica Ostetrica e Ginecologica Veterinaria. They found that testosterone levels rised 10 minutes after mating and then again 30 minutes into it. Cortisol levels also increased during the mating.

A study by Department of Pharmacobiology, Centro de Investigación y Estudios Avanzados was done on rats to measure sexual satiety and androgen receptors. The rats were measured after a sexual encounter. They measured the testosterone levels afterwards and found no change. They also measured a drop in angrodren receptor density, in the MPOA-medial part of the brain. This receptor density returned 72 hours later. It appears from this study, the lack of sexual desire post ejaculation, may have been from changes in the brain, not from changes in testosterone.

A study by the Department of Reproductive Biology, Universidad Autonoma Metropolitana-Iztapalapa found that testosterone levels stayed the same or rised, after various types of sexual encounters in male rats. The more experienced rats had a large increase in testosterone post-ejaculation, which remained even 24 hours afterwards. The sexually inexperienced rats however, had little change in testosterone post sexual encounter. This study suggests that sexual experience and execution, may play a role in the rise of testosterone.

Long term testosterone levels from abstaining ejaculation:

The only study I could find measuring testosterone levels of men who didn’t ejaculation for extended periods of time, was research done by chinese researchers, J Zhejiang Univ Sci. 2003 Mar-Apr;4(2):236-40. The study was done on 28 men who were told to not ejaculate for entire week. It was found that for first 6 days testosterone levels did not change. However, on the 7th day of abstaining, testosterone levels jumped up by nearly 50%. It then declined quickly after that day, therefore abstaining from ejaculation had no long term rising effect.

Summary:

What do these studies on animals and humans tell us about the relationship between testosterone and sexual activity? Many people have always assumed that after sexual activity, males experience a drop in testosterone levels. There is no research we could find that points to a significant drop in testosterone post-ejaculation. In fact research tells us that the opposite seems to be true. Men will have significant jumps in testosterone levels from sexually arousing stimuli(and certain other types of stimuli). The research also suggests that sexual encounters and ejaculation, will not effect and may increase, testosterone blood levels.

Viewing sexually arousing material, without ejaculating, before working out should be beneficial for improving workouts.  Ejaculating before working out, would probably not be ideal, since ejaculation also releases endorphins(pain killing) natural hormones in the body. This would in turn effect your strength and energy before your workout.

The chinese study also suggests that abstaining from ejaculation will not increase your Testosterone levels long term and hence, not improve your bodybuilding gains.  Recent studies are also showing a significant drop in prostate cancer risk, for men who more frequently ejaculate. According to current research, ejaculation (or sex) is not going to lower your testosterone levels, in either the short term or long term.

    i am 30 yers old recnt i have been noticeing my sexual activity going down and i went to doctor then i had tetostarn test it was lower as need.even panis not being rock hard can u tell me what to do.

  2. Philip on March 27th, 2010

    I would like to see the following research be done. I think these results are inconclusive due to many variables: see below

    masturbation with orgasm – but blunting no ejaculation
    masturbation without ejaculation or orgasm
    masturbation with ejaculation
    sexual intercourse with orgasm but blunting ejaculation
    sexual intercourse without ejaculation or complete orgasm
    sexual intercourse with ejaculation

    This is total bullshit.

    research,reasearch this, research that.

    how about you go research your a55?

    5ex and masturbation destroys vital energy. You dont need a scientific study for that. Its common sense. you feel extremely drained after 5exual activity for reason – it destroys core energy that is based around the abdomen area.

    Youll realise after 5ex sometime your lowerback hurts this can fcuk your deadlift up and your squats. This ‘research’ is bull5hit thats designed to make you lose hard-earned-gains.

    even if you eat really well youll notice losts in pump and strength.

    Why do pro athletes abstain from 5exual activity for months before fights/athletics events? Are they wrong? They earn millions and they are wrong. You are right according to your gay-ass

    ‘chinese-research’ wake the fcuk up.

    Great post there.

  5. david on April 15th, 2010

    I knew it was no coincidence that I chose to have displayed in my workout room the posters of a fitness babe and a fbb (Cori Nadine, Cory everson). Looking at them every now and then makes me work out quite a bit more aggressively! I want to do them and compete with their fitness levels at the same time

  6. navid on April 19th, 2010

    That was so nice ,thx alot,wish to get more n more here about it man!totally i think when before workout i do ejaculation ,ill feel lazy to work out but i have not feel that it effects on the weight i can lift or i mean effects on my power ,but most of the time when i am back to home ,i feel i need to have ejaculation,but my friends say that u r wasting the proteins in ur body,but it cldnt be true since the body recognize that how to provide the amount of different materials in body!

  7. Brett on May 6th, 2010

    Great article.

    I have to agree with some of the responses, in that I have experienced increased motivation, quicker recovery, and feel i have more power and endurance after (during) long periods of abstinence. The longest I have gone is 2 months and the reduction of all the above mentioned points is definitely perceivable after this period of time.

    I look forward to further research on this topic.

    And for those who want to abstain to try to improve their workouts, I found the first 10 or so days the hardest ( no pun intended ) but after that you can focus fairly well.

  8. Brett on May 6th, 2010

    Edit: I meant that I have perceived a reduction in motivation, power etc. after ejaculation post 2 months of abstinence. However, If I limit it to one sexual encounter the reduction is minimal. However if you have a total blowout and bang your partner silly all day, (or spank yourself raw,) the perceived reduction is greater. For me at least anyway.

    Yoked is big, big muscles, like on ox that’s in a yoke.

  10. Logan Symington on June 15th, 2010

    God. Let me break it down for you people.

    First of all, is what is really important testosterone or muscle gains?

    If testosterone then well, it seems inconclusive.

    Even so. i have not masturbated for 5 nights and I can tell you positively i have more energy.

    And simply having more energy (mental and physical i should add) will OBVIOUSLY help gain muscle mass, as you will be more on game, focused and not robbed of energy to go out and exersize.

    Simple

  11. TK Trent on July 3rd, 2010

    Thanks, really good post but still I need a definite answer.
    Does masturbate means to ejaculate?
    Can masturbating give you testerone that help in your growth?
    Or do you have ejaculate.
    If so, how frequent is appropriate for masturbating/ ejaculate.
    New to bodybuilding, so thanks for help

  12. There are certainly a lot of details like that to take into consideration. That’s a great point to bring up. I offer the thoughts above as general inspiration but clearly there are questions like the one you bring up where the most important thing will be working in honest good faith.

    Whenever I always decide to stop the habit, I get tempted by those explicit ads or images that pop up from certain websites. Well I try to stick onto the Jelqing instead of ejaculating. Now all I want to know is whether masturbation really hinders the muscle-development and Jelqing enlarge my length?

  14. Frank on July 20th, 2010

    What about ejaculating during your workout? Good or Bad???

  16. SportBoy on August 6th, 2010

    Good article and post. I really thanks to the author!

  17. Ivanru on August 20th, 2010

    I have noticed consistently, to such a degree that I beleive it must be fact, that the less I ejaculate and longer I abstain the healthier, and more energetic I feel. I am trying to ejaculate less because of this, but if I have a big party or outting planned I always ensure I have at least 3 day abstaining prior. So if the above article is correct it may not be testosterone levels but something else.

  18. dam on August 31st, 2010

    hey serious fuuck all this articles.. Everyone out there, if you want to be strong and work out well in the gym, and get your dream bodies, then dont masturbate at all.

  19. hisham on September 8th, 2010

    my opinion only….Ejaculation makes me weak in training (that’s my experience )

  20. zampano on September 20th, 2010

    I know of some “sadhus” (ascetics) in India who advocate celibacy. A TN prog. brought them head to head with a sexologist. The doctor said, even if you practise celibacy, you will discharge eventually. Its not possible physically to hold back.
    Other ascetics who ask people to practice it are idiots or thugs, who have been exposed as criminals. So, that axiom in Jail seems to hold true!
    Also, it would be interesting to see how much more incidence of Prostate cancer is there in the celibates.
    For real common sense purposes, heres a query. WHY would a guy build his body…? in most cases to better himself and to get a mate (chicks/ guys, whatever). So what does he do during mating? ejaculation is sine qua non. N’est Pas?
    And for the other posts who say that they go for days without… how do they do it…. and more importantly… WHY?

  21. Steroids sale on September 20th, 2010

    Great research on ejaculation. Go on.

  28. Hadi on November 24th, 2010

    I’ve realised that ejaculation even brings pooverty just with the food u have to eat in return and the bad luck that will follow u alone.

    I read in another site that an urban legend started to avoid having athletes staying out late trying to get lucky. This might also make sense for athletes staying up late watching e rotic movies, etc.

    This makes sense in that there is probably research suggesting that certain times of night will produce the most restful sleep and this time conflicts with normal times of s ex, ie right before going to sleep. As a married man, if I know I will not have s ex, I can fall asleep quickly whereas if it is up in the air, I will usually end up going to bed later, not getting a good night’s sleep when the sun and kids wake me up.

    The other part is the psychological part which has to do with thinking about strategy and visualizing the win and actions before falling completely asleep. If this is done, your sleep time may actually improve your mental state, thus preparing you for successful competition. I was taught that in order to learn something, you must study it and when you get it right, sleep on it, possibly letting the brain rewire itself with fresh information.

    The effects of celibacy on gym-performance and adrenaline is neither biological, neurological, nor psychological. It is all three. As a martial-artist and a dabbler in the functions of the mind-body relationships, I’m very intimate with this concept.

    As shown by the experiments so-kindly referenced by Mr. “Mofo,” we can all see as clear as day that abstinence contributes to stress-levels. Naturally, any sort of matter — be it living or unliving — will seek to alleviate stress in any way possible. Typically, ejaculation will relieve this stress the best; very much like dumping the contents of a bucket or perhaps as a far better example, going to the latrine for a leak after holding it for a uncomfortably long time.

    Let us use my last example as the case-scenario to best illustrate my point. A gentleman needs to use the bathroom, rather badly. Is he going to walk, or is he going to run? The biological need to regularly ejaculate generates such a similar stress during times of celibacy, the body is denied this and so a process called “displacement” begins. Driven by the desire burning inside of you body, you will be under greater stress and therefore even produce higher levels of testosterone — exactly as if you were holding a gun and yearning for nothing more than to fire it at something. The barrel /must/ be emptied, and if you can’t pull the trigger you’re very likely to maul something with it instead.

    If you want to prepare yourself for high-yield and incredible intense work-outs, celibacy to the point of torturous is perfect. I’m sure a clever girl somewhere would point at this information and say it’s the reason she doesn’t put out often, but such crock is only useful in making for a particularly good day at the gym. I fear I begin to digress, and I hope this knowledge is useful.

    This article was very helpful, but has anyone ever heard about when ejaculating vital nutrients are released that would help in athletics, strength gains, and size gains?

  32. testosterone workout on February 9th, 2011

    I combined used the Dr Max Powers Testosterone Booster I bought a while back and absolutely love it. It is much more effective than the silly power drinks that some of the guys drink in the gym. Use this if you are working out or an athlete that wants to recover faster from tough work outs, spice up your sexual life, or just help restore your testosterone levels to what they used to be when you were younger.

    Thanks man i’m a big time lifter this question has been bugging me for a long time.

  34. Dave on February 25th, 2011

    I whack it all the time and I’m ripped.

  35. Missy on March 8th, 2011

    yoked means ripped, silly…. so I have a question about all this ejacualting…can my boyfriends semen cause my levels to rise? I dont want to gain weight too!

  36. smz on March 11th, 2011

    Uh, no one has said squat about vasectomies and how that would alter lose of protein or testosterone levels?
