This current study examined the effect of a 3-week period of sexual abstinence on the neuroendocrine response to masturbation-induced orgasm. Hormonal and cardiovascular parameters were examined in ten healthy adult men during sexual arousal and masturbation-induced orgasm. Blood was drawn continuously and cardiovascular parameters were constantly monitored. This procedure was conducted for each participant twice, both before and after a 3-week period of sexual abstinence. Plasma was subsequently analysed for concentrations of adrenaline, noradrenaline, cortisol, prolactin, luteinizing hormone and testosterone concentrations. Orgasm increased blood pressure, heart rate, plasma catecholamines and prolactin. These effects were observed both before and after sexual abstinence. In contrast, although plasma testosterone was unaltered by orgasm, higher testosterone concentrations were observed following the period of abstinence. These data demonstrate that acute abstinence does not change the neuroendocrine response to orgasm but does produce elevated levels of testosterone in males.

Thats to general. They don't refer to how free test was altered or by what degree it was altered. The difference could have been so minor that its not worth noting. Also it may only be a short term respons due to a decrease in receptor affermity(sp) in the gonads. Since they are binding less the rate of denaturing would be decreased and possibly have a positive effect of blood plasma levels. But over the course of time the body would most likely correct this by lowering the output.

Untill I see a more specif study(more than abstract) I'll consider any correlation between waking it and BBing to be nonsense.

Are you referring to 'affinity'?

Ha, yeah I believe that would be it. It a little to early on sat for thinking. Probally several other similar errors in my post also.

[llama1917]

well anyway even if thats true, who gives a fukc

given the choice between being built like jay cutler, or being able to cum, i'd take the latter...

[Luke530]

the stress of worring about having lower testosterone levels through masturbation, and the stress of abstinence would probably lower testosterone and raise catabolic hormones moreso than masturabtion itself... if you feel the need, don't dissapoint

[amusclehead]

who cares, just don't whack it before u lift

[Mingo]

So as a general rule, regardless of mastrubation affects on testosterone levels at all in any way, just keep jerking off to a minimum, maybe only when you see some hot girl and are near a bathroom .

That study says nothing about masturbation lowering test - it says if you abstain from cumming for three weeks you will have higher T levels than if you had cum.

[EAE]

I guess I'll have to cut down to masturbating only once per day

[*WiNgS*2]

im not saying masterbation lowers test but it really does drain your energy

You are so incredibly bright, that I may just have to like kick my mom right in the face.

[GDS10]

Wat if u ate the cum after u came

LOL JOKING

erm,,,, ya but it is quite good to do it, before u goto sleep to help u actually get to sleep, if u cant sleep

Eh?

Sex Increases Testosterone
by Gisela Henriques

Sex before a game can actually improve an athlete's performance, say researchers.

A recent study conducted by Italian researcher Emmnuele Jannini, from the University of L'Aquila proves that the levels of the testosterone hormone rise after having sexual intercourse.

This study tears apart the previous belief that if players were deprived from sex before a match they would have a better performance on the field because testosterone is often related to aggressiveness.

Researchers from the University of L'Aquila measured the levels of testosterone in the blood of more than 80 patients that suffered from long-term impotence. The results were to show that the amount of that hormone was two thirds of those with sexual active lives. After several months of therapy - that did not include hormone treatments-, the researchers found that the men that were treated with a reasonable success had an increase of their testosterone level, while the ones that did not respond to the treatments continued to have low production of testosterone.

The increase in the sexual activity made the researchers believe that the raise in the level of that hormone is related to the amount of sexual activity one has. Jannini told the English scientific journal New Scientist that he believes that in men " the body adjusts testosterone levels to match sexual drive to the sexual activity. If he [athlete] needs to be more aggressive it's better to have sex", he concludes.

Although it was known that inadequate levels of testosterone may cause depressed mood, lack of motivation on men and decreased energy, it was never established a correlation between the amount of sexual activity and its direct impact on the testosterone levels. Doctor David Handelsman, who studies reproductive medicine in the University of Sidney, also told New Scientist that Jannini's research was the " first clear evidence in the vexed relationship between male sexuality and testosterone", and that the previous researches did not provided any evidence of the levels of this hormone before and after treatments were induced in patients.

It is still fresh in our memories the controversy surrounding the Portuguese football coach's decision to prevent his players to have any contact with their wives during the 1996 European football tournament. His argument was led by the belief that his team would have a good performance if they did have any sexual activity on the nights previous to the games. On the opposite side were the Scandinavian coaches, who encouraged their players to go on with their conjugal duties. The overall final scores proved that perhaps the Danish and Swedish were right, and now scientific proof makes it even clearer why they had better results. On the verge of the classification to the Euro-2000, surely the Portuguese coaches will take these facts into consideration for a far better result.

Abstract

We have recently documented significantly reduced serum testosterone (T) levels in patients with erectile dysfunction (ED). To understand the mechanism of this hypotestosteronemia, which was independent of the etiology of ED, and its reversibility only in patients in whom a variety of nonhormonal therapies restored sexual activity, we measured serum luteinizing hormone (LH) in the same cohort of ED patients (n=83; 70% organic, 30% nonorganic). Both immunoreactive LH (I-LH) and bioactive LH (B-LH) were measured at entry and 3 months after therapy. Based on outcome (ie number of successful attempts of intercourse per month), patients were categorized as full responders (namely, at least eight attempts; n=51), partial responders (at least one attempt; n=20) and non-responders (n=16). Compared to 30 healthy men with no ED, baseline B-LH (mean±s.d.) in the 83 patients was decreased (13.6±5.5 vs 31.7±6.9 IU/L, P<0.001), in the face of a slightly increased, but in the normal range, I-LH (5.3±1.8 vs 3.4±0.9 IU/L, P<0.001); consequently, the B/I LH ratio was decreased (3.6±3.9 vs 9.7±3.3, P<0.001). Similar to our previous observation for serum T, the three outcome groups did not differ significantly for any of these three parameters at baseline. However, outcome groups differed after therapy. Bioactivity of LH increased markedly in full responders (pre-therapy=13.7±5.3, post-therapy=22.6±5.4, P<0.001), modestly in partial responders (14.8±6.9 vs 17.2±7.0, P<0.05) but remained unchanged in non-responders (11.2±2.2 vs 12.2±5.1). The corresponding changes went in the opposite direction for I-LH (5.2±1.7 vs 2.6±5.4, P<0.001; 5.4±2.2 vs 4.0±1.7, P<0.05; 5.6±1.2 vs 5.0±1.2, respectively), and in the same direction as B-LH for the B/I ratio (3.7±4.1 vs 11.8±7.8, P<0.001; 4.2±4.3 vs 5.8±4.2, P<0.05; 2.1±0.7 vs 2.6±1.3, respectively). We hypothesize that the hypotestosteronemia of ED patients is due to impaired bioactivity of LH. This reduced bioactivity is reversible, provided that resumption of sexual activity is achieved regardless of the therapeutic modality. Because biopotency of pituitary hormones is controlled by the hypothalamus, LH hypoactivity should be due to the hypothalamic functional damage associated to the psychological disturbances which unavoidably follow sexual inactivity.

Continued.....

The role of androgenic hormones in human sexuality, in the mechanism of erection and in the pathogenesis of impotence is under debate. While the use of testosterone is common in the clinical therapy of male erectile dysfunction, hypogonadism is a rare cause of impotence. We evaluated serum testosterone levels in men with erectile dysfunction resulting either from organic or non-organic causes before and after non-hormonal impotence therapy. Eighty-three consecutive cases of impotence (70% organic, 30% non-organic, vascular aetiology [etiology; the set of factors that contributes to the occurrence of a disease; red] being the most frequent) were subjected to hormonal screening before and after various psychological, medical (prostaglandin E1, yohimbine) or mechanical therapies (vascular surgery, penile prostheses, vacuum devices). Thirty age-matched healthy men served as a control group. Compared to controls, patients with impotence resulting from both organic and non-organic causes showed reduced serum levels of both total testosterone (11.1 +/- 2.4 vs. 17.7 +/- 5.5 nmol/L) and free testosterone (56.2 +/- 22.9 vs. 79.4 +/- 27.0 pmol/L) (both p < 0.001). Irrespective of the different aetiologies and of the various impotence therapies, a dramatic increase in serum total and free testosterone levels (15.6 +/- 4.2 nmol/L and 73.8 +/- 22.5 pmol/L, respectively) was observed in patients who achieved normal sexual activity 3 months after commencing therapy (p < 0.001). On the contrary, serum testosterone levels did not change in patients in whom therapies were ineffective. Since the pre-therapy low testosterone levels were independent of the aetiology of impotence, we hypothesize that this hormonal pattern is related to the loss of sexual activity, as demonstrated by its normalization with the resumption of coital activity after different therapies. The corollary is that sexual activity may feed itself throughout the increase in testosterone levels.

Uhhh...last time I checked, don't you cum when you masturbate? If not I must be doing something wrong......

Did you not read the study? If you ABSTAIN for three weeks you will have higher test - it says nothing about the immediate effect of masturbation on testosterone levels. If you don't masturbate for three weeks you'll have higher test - that doesn't mean that masturbation lowers test it justs means that not masturbating for a period of time gives higher levels.

[_teddy_]

ok the only way to settle this is to have two genetic identical twins taken into the test. have one jerk everyday and workout the same time the other one and deprive the other one of cumming. have them do the same exercises and same intensity and see who has greater gains after 10 years

seriously though i think it has an effect. first of all after you cum you just squirted a load. that is protein and all the other goodies, that coulda been put into your muscle gains, instead now that you shot the load your body has to use up resources to reproduce the sperm. also something about how your body drains the testosterone to your balls during sperm production so it means your muscles and overall body gets less... for sure after sex or masturbation you lose that aggressiveness that is prob needed to push that extra weight too

the funny thing is though, ive tried not jerking for like 2 weeks. i mean there were times when it was really hard to hold but after a while you kinda get used to it. but then after that once i jerked after 2 weeks, i could recover so fast... so like in a few minutes i was ready to go again and again and end up jerking a few times in a really short time..

man i did a search on this juist now because i wokeup with a huge boner and wana wack but i also planned to workout later today... damn it im just getting my mind off this **** right now by typing stuff in the forum.. i guess i wont wack right now then... prob tonite or something but damn it... somebody needs a real answer to this question...

You probably should have checked the date on the original posts to see that they were over 2 years old before proposing your settlement.

ha and ya'll can watch the live porno flick of me and her ;-)
