Ejaculation and Testosterone Levels: Does Masturbation Really Lower Testosterone?

One of the more frequently asked questions I get is around the topic of ejaculation and testosterone is;

Does masturbation increase or decrease testosterone levels?

That’s a valid question since the internet seems to be loaded on opinions about the topic.

Obviously, it makes a lot of sense that ejaculation, masturbation, and having sex could all lower T levels, since 95% of the good stuff is made in the gonads, and during an ejaculation you’re basically dumping the contents away, but even if something “makes sense”, doesn’t always mean it’s correct.

The topic of refraining from ejaculations itself has been talked about for years, and many athletes are known for their habit of abstaining from sex before big events, such as: Mike Tyson, who abstained because he felt like having sex before fights made him a “weaker boxer”. Or another boxing legend – Muhammad Ali – who wouldn’t have sex for 6 weeks before his big fights.

Athletes aren’t the only ones who avoid ejaculations for a “greater cause”. Many highly successful men of the past have also abstained in order to use the sexual energy as a fuel for other things, these guys include: Napoleon Bonaparte, Thomas Jefferson, George Washington, Oscar Wilde, William Shakespeare, Abraham Lincoln, and many more.

But does any of the above have to do with testosterone? Or is it just a mental thing? And do ejaculations or masturbation even lower testosterone levels in the first place?

Ejaculation and Testosterone

Ejaculation and Testosterone productionIt’s almost like a big taboo to even talk about this very topic, and it’s funny to see how some men get all angry when they don’t like what they see.

With that in mind, I’m going to just go through some of the actual scientific research about masturbation, sex, ejaculations, and testosterone – in animal and human subjects – objectively.

If something below doesn’t justify your porn addictions, or if it just makes you get all hot and bothered, please leave the site and never come back. I’m not here to instruct you how often to have sex or masturbate, this post is just here to show you the real evidence behind masturbation and testosterone levels.

So, here’s some of the research:

a) It’s known that short-term abstinence of 3 weeks can slightly increases testosterone levels in healthy human subjects, and one interesting study shows a significant 145% spike in T at the 7th day of abstinence (probably an evolutionary trigger to reproduce). However, long-term abstinence of 3 months has been shown to significantly reduce testosterone levels (note that this is only researched in men with erectile dysfunction, so the low T can be caused by something completely different).

b) In multiple human and animal studies, it has been noted that ejaculation does not acutely change serum testosterone levels, busting the common myth that ejaculation would rapidly deplete the body from testosterone (study, study, study, study).

c) Even though ejaculations seemingly have no significant effects on serum testosterone levels, they can (at least according to rodent studies) alter the body’s ability to utilize testosterone. It has been seen that after multiple ejaculations a sharp decline in androgen receptors takes place inside the hypothalamus, and not only that, but a sharp increase in estrogen receptors follows as well. One rodent study also found out that 1 or 2 ejaculations in short span of time increased androgen receptor activity in the body, while 4 or more ejaculations caused a significant drop in the activity of AR, suggesting that ejaculating yourself to “sexual exhaustion” might lower your body’s ability to utilize androgens.

d) While masturbation induced ejaculations don’t seem to have that big of an effect on serum testosterone levels, sex with a real person does. For example: In a study of 44 men visiting a sex club, it was noted that the men who actually had sex in the club with a woman, noted a nice 72% average increase in their testosterone levels, while the men who only watched the act, got a boost of 11%. In another study, it was seen that on couples, testosterone levels increase on the nights that they have sexual intercourse, but not on the nights that they don’t. One study also saw that older men who have more sex, have higher T levels. What causes this if ejaculations don’t? It could be the interpersonal touch, the female pheromones, the feelings of dominance, power, and even success…

Conclusion on Ejaculation and Testosterone

Ejaculations and their effects on testosterone is quite an understudied topic on humans, but from the current evidence, we can draw the following assumptions on testosterone and ejaculation:

  • Short-term abstinence from ejaculations can slightly increase testosterone levels.
  • Long-term abstinence can reduce serum T.
  • Having an ejaculation does not acutely affect testosterone levels.
  • Ejaculating to the point of “sexual exhaustion” can make it harder for your body to utilize testosterone.
  • Masturbation doesn’t seem to affect testosterone levels in any significant manner.
  • Sex with a real person can boost testosterone levels significantly.

All-in-all, these are all assumptions from the human & animal science above. More human research around masturbation and testosterone levels would not hurt, and if you can find some, please link them in the comment section below.

If you are looking for a natural supplement to boost your testosterone, I would recommend TESTRO-X.

    I don’t think here is enough evidence, that long term abstience can lower T. From personal experience when I abstain ( 1-3 months) from ejaculation I get more confidence, my libido skyrockets, and voice gets deeper (but this could be an effect of quitting porn). This also happened to my friend who doesn’t watch porn. Have you ever tried it?
    Maybe it makes the receptors stronger, who knows.

    • John on 08/04/2016 at 01:57

      i think this is the case. it’s not necessarily that you make more testosterone, but regenerate the receptors

  2. The real lebanese on 11/07/2015 at 06:33

    Ali, I would’ve expected you to include the sharp increase in prolactin about an hour after busting. What are your thoughts on this?

  3. The McDougal Bugle on 11/07/2015 at 07:16

    What about Dopamine and Cortisol?

  4. Mahmoud on 11/07/2015 at 08:27

    Hey ali I snapped my back a few days ago now I can barely deadlift or squat? Should I let the back muscle recover itself or do you know of a prescription drug that won’t lower t levels?

    • John on 08/04/2016 at 01:59

      you can get testosterone prescribed to you if you feel you have low t

    • jerrycollie on 05/02/2017 at 16:24

      Rub drugstore Cortizone10 on your back before you go to bed every night until it heals up. May take a few days or a month or 2, depending on how much damage you did. Add weights slowly when you go back to lifting. Don’t do the one-rep max with the squat or deadlift, unless you want back trouble.

  5. bob on 11/07/2015 at 23:56

    Anyone who has abstained from masturbating for longer than a month can tell you that there is definitely something that happens to your testosterone. I was like an animal.

    • samlebon23 on 24/07/2015 at 19:08

      Don’t ever do that again, we are designed to eliminate excess from our bodies.

      • bob on 24/07/2015 at 19:52

        Nah, I felt great the whole time. If you are not releasing excess from your body it will adapt and stop producing so much sperm.

        • John on 08/04/2016 at 01:55

          either that, or you’ll experience a wet dream.

      • Shawn Baskette on 13/03/2016 at 21:49

        You’re an idiot. Your body removes excess on it’s own through nocturnal emissions.

        • John on 08/04/2016 at 01:54

          “it’s” isn’t possessive. it means “it is”. “its” is the possessive. I love idiots who call others idiots 🙂

          • Shawn Baskette on 08/04/2016 at 02:37

            Really? because I hate people who try to police grammar on the internet.

          • John on 10/05/2016 at 21:43

            oh is that what you hate? because i was really wondering what your likes and dislikes were. thanks so much. what’s your favorite color?

          • Brock Holmes on 08/04/2016 at 17:04

            You are everything that is wrong with humanity.

          • John on 10/05/2016 at 21:41

            yes, because actually being informed is what’s wrong with humanity, right. how can you think education is wrong? it looks to me like you and others like you are what’s wrong with the world. You rather everyone be an uneducated neanderthal in order to feel like there’s nothing wrong with being as stupid and lazy as you are. You are a nobody and will always be a nobody. Just remember that, clown.

            Toodles, loser.

      ” I was like an animal.”
      Can you elaborate on this point? I’m aiming for a month (currently on day 5 now), so I’m curious to know ..

      • Slim Jesus - Chiraq Caillou on 08/10/2015 at 09:15

        just like my sex drive was through the roof. Also, I had alot more confidence and was not as socially awkward as much

        • FindingAtlantis on 02/11/2015 at 03:17

          Yes, I’m mainly interested in the socially anxiety aspect. How long did it take to feel fully confident? Did the confidence keep increasing with abstinence? Or did it level off after 1-2 weeks?

  6. Impressive Nutrition on 16/07/2015 at 07:30

    Am I the only one wondering how they got a mouse to ejaculate 4 times rapidly to sexual exhaustion?

    • samlebon23 on 24/07/2015 at 19:07

      Probably they designed a micro-Fleshlight for the mice.

      May be they used so called “chemically induced ejaculation”, which normally used for Horses. Not sure, of course !

    what is the reason for this ??
    please reply


  10. p martin on 21/05/2017 at 04:23

    Just a thought….what is the T level of a henpecked husband whos wife determines when sex happens and how. There isnt feel of dominance or power.

  11. juntjoo on 22/05/2017 at 05:47

    It’s unbelievable how difficult it has proven to be to abstain. I succeeded for about a day till I accidentally scratched my balls and my palm brushed up against the head. One thing led to another. It is quite a matter of self discipline

  12. Optimus Primal on 02/06/2017 at 16:53

    So the ideal then is obviously to have sex as many times as possible with a woman without ejaculating then only cumming once a week (preferably in her mouth so she will think you’re superman).

  13. 6fondue on 20/06/2017 at 03:25

    Great article, well written and god conclusions of collected data.
    How ever I am still curious if creating a “shortage” of sperm and decrease of testosterone by cycles of repeated ejaculations during a short period of time, maybe during the course of hours followed by “rest-days” if that over time would provoke the body to produce more Testosterone and sperm in a response to “progressive overload”.
    Since this is the way the body handles a lot other things that challenges it´s system with everything from resistance-training, “repeated skin-abrasion”, bacteria and even some toxins.
    CHEERS !

  14. The Waifu Slayer on 19/09/2017 at 23:55

    It doesn’t matter much how inconclusive the results are; even if its placebo, you can definitely feel the difference when you abstain for a couple days or weeks. More solid proof is that fact that I can literally do more reps in the gym when I don’t masturbate for a few days.
