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 was going along, searching for some info on Female Sexual Desire, and saw a link here. You can bet I’ll be bookmarking this site TODAY (Tuesday). Great post!

Sounds good to me.

chuck DIESEL on February 27th, 2008

thanks… I always wondered about that. When I was in jail all the guys said not to do it because you lose protein and testosterone.. guess that’s why they’re in jail.. complete dumbasses.

It defenitely decreases my nrg pre-work out tho. As long as it isn’t messing with my test/protein levels thats cool.

ali on April 11th, 2008

great post.. but one question remains….how often is often?? is ejaculating once a day normal or abnormal? it would have helped a lot if the article mentioned numbers instead of abstractions

Dec on April 13th, 2008

True story Chuck…

There’s been a long going folklore in jail about ejaculating effectively lowering your ability to build muscle. It always seemed reasonable to me in theory, but I guess it’s all bullshit.

admin on April 14th, 2008

Ali, I can’t answer everything. I try to write most of my articles based on fact or logical thinking, but those kinds of detailed questions I couldn’t answer.

Manuel Hernández on May 20th, 2008

This had been a poignant question for me. Thank you.

After reading your text, it makes sense frome an evolution point of view. An Alfa male should be able to maintain strenght AND ejaculate several times in a row to reproduce as much as possible.

Therefore, maintaining a high level of testosterone to produce muscle, and libido, is likely to happen after ejaculation, and even after several occasions. This would be certainly useful in the natural selection of mammals. Thank you again, and my best regards.

armin on June 5th, 2008

Hmm, dunno about that. It is said that it takes 48 hours for your sperm to rebuild itself after ejaculation and it is mostly made out of proteins. So, when you think about it, you lose valuable proteins for two days after ejaculating (about 20 to 30 grams or 10-15g a day).

admin on June 5th, 2008

Well, your body constantly makes semen anyways and if its not used, it just absorbs it back in the body.

Its not like its going to take the protein from the rest of our body anyways. That would be like saying if we work our arms, it take away our efforts from building our chest.

raj on June 7th, 2008

its good to get important information about this topic.people mostly are in doubt that sexual activity does not affect bodybuilding.thank for giving this information.bye…….

Dave on June 17th, 2008

Personaly I have found that after not doing it for about two weeks my progress in the gym improves dramaticaly.

Daniel on June 27th, 2008

I have learned a lot about the increase in male power through “keeping it in” or not ejaculating for long periods. All major worlds religions seem to say similar things about this. Myself, I have

noticed increase energy as well as success in other areas of my life. Learn more at celibacy.info.

admin on June 27th, 2008

There might be some kind of boost from celibacy, but its not due to testosterone. Maybe psychological reasons or for some other reason.

dan on July 30th, 2008

Abstinence does increase testosterone according to this, but orgasm does not change blood level in the short term.

patrick on August 3rd, 2008

Thanks for gathering the research and writing the article. It doesn’t sound like a very big loss of protein. When you are working out and eating right you are adding lots of protien, so it doesn’t sound like a problem in that department. I always wondered if the change in hormone levels (testosterone?) was anti-muscle building. In conclusion…I’m not changing my social agenda with myself…

Rob on September 9th, 2008

Cool article, sounds like a lot of hard work.

So I want to make this clear: ejaculation AFTER work outs (body building) is BENEFICIAL? What is? What is not?

Best regards. Thanks.

Chris on September 16th, 2008

I have to agree with some of the guys above about an increase in performance deriving directly as a result of sustained abstinence. I don’t have the time, resources or inclination to perform a conclusive experiment but certainly speaking for myself, I feel my testosterone levels definitely increase during periods of sustained abstinence.

I believe that (possibly) if you abstain, that your body naturally produces more testosterone to “pump you up” as a means of helping you further your gene and is a reaction dating back to the caves.

But again I have found no concrete proof of this -just my own anabolic and hormonal changes.

WankingBodybuilder on September 20th, 2008

Would masturbation and intercourse with a partner have the same effect on your body afterwards? I mean in the end it’s your juice that comes out, which ever the method was….

Please get back to me on this

Haha, u tosser, go toss it off

tom on January 27th, 2009

According to a book called War and Gender, there is a difference in testosterone levels between intercours versus masterbation – after sexual intercourse testosterone increases greatly, wheras after masterbation, testosterone hardly rises.

daniel frazier on January 29th, 2009

Wow. The others that responded to this are

Mentalmidgets, I can’t believe those posts

Are real!

admin on February 2nd, 2009

Tom, Id be curious to know if they have studies to show it.

daniel is a n00b on March 13th, 2009

Abstaining from jerkin it has got me yoked. I’ve also notice that it has been easier to make hard gains in the summer because my body isn’t constantly using energy or calorie intake to maintain heat.

Mofo on March 18th, 2009

What happens after a few weeks of abstinence? Two studies shed light on how a body changes after a sxual dry spell.

Before a big day: A study of 46 men and wmen in Scotland looked at whether sx affects the body’s blood-pressure response to a stressful event — in this case, a nerve-racking combo of public speaking and verbal arithmetic. The results, published in 2006 in the journal Biological Psychology, showed that people who’d had no sxual activity (no intercourse of any kind, no masturbation) in the two weeks before the stressful day had the worst blood-pressure responses. Those with the best reactions? Folks who’d had penile-vaginal intercourse only. (Those who’d had other types of sxual activity with another person still fared worse than those who’d had vaginal intercourse; masturbation was barely an improvement over no xual activity.)

Before a big night: A study of 10 German men, published in the World Journal of Urology in 2001, looked at how three weeks of no sxual activity can affect orgasmic responses — in this case, during an evening of ertic movies and masturbation in the lab. Compared with a similar session before their abstinence, the men were more sxually aroused by the film, and their orgasms were longer and more intense. (They reported that the finale did not arrive any more quickly than usual.) What’s more, after the three-week period the men’s testosterone levels were elevated, which is known to boost libido — an effect that persisted throughout the film and even after orgasm.

Wow, that’s full of grammatical and syntactical errors. Go back to school.

nick on July 29th, 2009

so can someone give a definitive answer, i couldn’t tell from the article or others comments.

mehmet on September 2nd, 2009

thnx for the research and article …i was thinking the same way as the article says:)

the more you do the more you want and the more you ready ( because of testesteron levels in blood)

the less you do ,the less you re ready as in life

but it doesnt mean do it everyday

just 3 times a week is enough to keep u high:)

rishi on September 13th, 2009

plz tell me its good or not 4 build muscle or at bodybuilding time means comp. time

masturbation is good or not,

did it effect on body or muscle plzzzzzz tell me the right thing

Doobi on September 21st, 2009

I think more research needs to be done on this, especially the long term effects on testosterone levels.

I personally feel better the longer I abstain from s e x\masturbation.

MJN on September 21st, 2009

Hey thanks for that info but I have a question!

I think I have the chronic masturbation syndrome and I am just wondering is doing it 7days a week unhealthy?…. because I just can’t help it I need rehab.

Ashim Sharma on September 29th, 2009

Actually I had a test regarding my testosterone level and it was found double than I actually need i.e. more than 1100 in normal condition and found that higher level of testosterone is causing me “Rapid Premature Ejaculation”..I would like to k now if there is something I can do to cure my rapid premature ejaculation reducing my testosterone hormone level.

BRENDAN on October 13th, 2009

I dont understand, why are people being arsey on here, this is a discussion not a brawl, i am a 16 year old bodybuilder and even i know we all want the same thing, so y not try and work in harmoney, and brilliant post it helped a lot thanx.
