    Being a weightlifter im sick of me and my friends arguing if masturbating or not affects us much.

    Lets use the "oh so original" twin examples!

    Two twins have had the exact same diet and lifestyle their entire life, and now their plane crashes into the mountains where they survive while the other unfortunate passengers are burned to crisp. They each have the same food supply rations from the wreckage.

    They would normally survive exactly 45 days each, with what they have - before dying.

    Twin A masturbates (to the point of orgasm/Ejaculation ofcourse) 2 times a day each day.

    Twin B never masturbates.


    Will twin A die 1 day or more before twin b?

    I don't have an answer but I think it's cool that you lift. I lift too. I do know that Eunuchs supposedly live longer than their testicled male courterparts..can't recall where I heard it though...

    twin A would die first but probably from the effort of the actions rather than the actuall production of sperm.

    The effect is hilariously negligable. However, with exercise and weightlifting, refraining from masturbation is actually beneficial. It provides one with more energy, not because it conserves energy, but because the neurchemicals (prolactin, for example) are not released into our brains.

    Prolactin is basically a chemical that, when introduced to the brain, causes us to slow down and "relax". Were it not for this and other chemicals after orgasm we would never stop masturbating or copulating. EVER.

    So it's only a good idea for exercise, and ONLY exercise. If you can do it. In regards to survival, it's not applicable. Not in the LEAST.

    I strongely suggest that for survival you find a specific receptacle to masturbate in.

    That is in the genital tract of a fertile woman.

    To answer the initial question, yes, masturbation requires an energy expenditure just like anything else. Yet, as Darius says, "the effect is hilariously negligable". We all generally take in more kilocalories than we can burn everyday and have energy to waste.

    sperm is considered very cheap. if you think about it in relation to the energy used to create an egg...all a woman's eggs are there by the time she is born. a man, however, continues to create sperm day in and day out throughout his life. the average man has millions and millions of sperm per ejaculation. and masturbating twice a day would certainly lower it but not to the point where it's no longer viable. its actually kind funny when you think of how little energy the male body puts into making sperm.

    now if you're talking about energy required to masturbate...well i can't help you on that one considering im a girl and have no idea how much energy you guys expend in masturbating. i think if your using that much energy to get off, youre doing something wrong lol

    After masturbation especially orgasm, the body releases specific hormones to relax the body therefore the muscles. And that is why you should not masturbate before a workout but after is ok cause it relief tension and stress.

    Also, just remeber, if your heart is pumping well, there is enough energy production to support you. Or just do a Basal Metabolic Rate (BMR) test and eat from that value (but find a reliable source).

    I did a check on the literature on the energetic costs of sperm production the other day and couldn't really find many concrete figures.

    What was interesting was that there was a lot of variation in the energy pathways used by sperm in different species.

    Some species actually have female genital tracts laced with sugars (that sperm use) and others don't.

    Things like that.

    Quite interesting..

    on some level.

    I guess Wanda Sykes wasn't kidding when she said she had "sugar walls".

    Here's a paper I came across (what an awful pun!): "How costly are ejaculates for Japanese macaques?". Unfortunately it's behind a pay-wall, so all I can see is the abstract:

    Much sexual selection theory is based on the idea that ejaculate is cheap. Since further details are unknown our aim was to determine the energy that primate males require for ejaculate production. We addressed this problem by measuring the energy content (in kJ) of ejaculates from Japanese macaques (Macaca fuscata) using standard bomb calorimetry. Then, we estimated the relative amount of energy that individuals require for ejaculate production by relating the net energy content of ejaculates to males' daily basal metabolic rate (BMR). Fresh macaque ejaculate contains 3.0 kJ ml(-1). Assuming a mean volume of 2.7 ml an average macaque ejaculate contains 8.1 kJ. Depending on the individuals' body mass (6-13 kg) and the number and volume of the ejaculates, macaque males are assumed to use between at least 0.8% and at most 6.0% of their BMR for ejaculate production per day during the breeding season. Even when regarding only the minimal energy investment of 0.8% of daily BMR for ejaculate production, clearly ejaculates come with some cost for primate males.

    I dont really think that it will make a difference when it comes to lifting. Sperm are relatively cheap to make and do not require much energy to produce that is why we make millions a day and we dont get tired from it. With the plane crash question we are also over looking any physiological responses that can come from masturbation, possibly the man masturbating could live longer due to he is a little happier or so on.

    The original question is interesting, (the twins) they have crashed into the mountains, presumably high up (otherwise they'd just walk to safety) the guy who masturbates would live the longest, he has simply found a way to keep his muscles moving and thereby generate the neccessary body heat to sustain his life further in the cold of extreme altitude, the other guy is history. 8)

    I know scientists have been experimenting on semi-starvation with animals to see if they lived longer. The semi-starvation method would work in theory because the body is reserving the production or release of energy. However, nothing absolutely conclusive has been found yet, as far as i am aware.

    But may i ask, if it did impact your energy, how the fuck would you stay away from masturbating... because... i'd go nuts if i couldn't. Are you willing to really give that up for mere muscles?

    Some people are addicted but if you have a hobby it is easy to break any habit. Yogis excersized abstaining from masterbation in order to channel the energy from our lower chakra upward. Their theories may not be valid, but their practices have been successful for thousands of years.

    All I know is that after a while of not masterbating, you are generaly more energetic. It might be sex drive telling you to go out and find something to screw, or it might be a way to block out the fact that you want to screw, whatever the reason. I say try it.

Some yogis preach abstaining from masterbation in order to channel the energy from the 2nd chakra upward to our 3rd chakra which supposedly gives us more physical vitality. Their theories may not be valid, but their practices have evolved over thousands of years.

It might be sex drive telling me to go out and find something to screw, or it might be a way to block out the fact that I want to get off, whatever the reason, based on my experiences with abstinence, I say try it.

    Generally-speaking for me, i couldn't. I actually become crabbit when i do not do it.
