1. Orgasm increases prolactin levels:

"This series of studies clearly demonstrated that plasma prolactin (PRL) concentrations are substantially increased for over 1h following orgasm (masturbation and coitus conditions) in both men and women" - Neurosci Biobehav Rev. 2002 Jan;26(1):31-44.

2. Prolactin-deficient animals show greatly decreased body fat storage with no changes in feeding habits:

"The absence of PRLRs in knockout mice was accompanied by a small (5-12%), but progressive, reduction in body weight after 16 weeks of age. Females were affected to a greater degree than males. The reduction in weight in female PRLR-deficient mice (age 8-9 months) was associated with a 49% reduction in total abdominal fat mass and a 29% reduction in fat mass expressed as a percentage of body weight." - Endocrinology. 2001 Feb;142(2):532-7.Click here to read

3. Inhibiting the action of prolactin results in fat-loss and apparent muscle-gain, even without changed in feeding habits:

"Reductions of prolactin secretion by...treatment for 24 days reduced fat stores (abdominal and epididymal fat depots) in hamsters by 25-49% compared with control animals. However, body weights and food consumption were not affected. These results further substantiate an important role for prolactin in regulation of fat metabolism" - Experientia. 1987 Apr 15;43(4):416-7.

4. Increasing prolactin levels causes an increase in body-fat, especially abdominal fat:

"We have recently show marked disruption of reproductive function and weight gain in female rats treated subchronically with [prolactin-increasing drugs]...induced significant weight gain with...increases in ...intra-abdominal fat." -J Psychopharmacol. 2004 Jun;18(2):149-55.

"Weight gain is a common and severe side effect of... [prolactin-increasing] drugs...The results showed [these drugs] increase body weight and subcutaneous fat deposition." - Psychopharmacology (Berl). 2006 Sep;187(4):447-54.

"increased body weight is associated with prolactinomas [prolactin-secreting tumors] and that weight loss occurs with normalization of prolactin levels [treatment with prolactin-inhibiting drugs]. On the other hand, decreased dopaminergic tone in humans is well correlated with obesity. [prolactin-inhibiting drugs increase dopamine neurotransmission]" - European Journal of Endocrinology, 2002, vol. 147, no1, pp. 77-84


It is satisfactorily demonstrated:

1. Lowering prolactin tends to result in body-fat reductions -- especially abdominal fat
2. Increasing prolactin tends to result in body-fat increases
3. Orgasm increases prolactin


Conclusion:

Orgasm initiates a series of biochemical processes whereby increases in body-fat -- especially abdominal fat -- and decreases in muscle may occur. Further research is needed to establish a contributory role of orgasm in the process of lipogensis and abdominal obesity, and whether or not this process occurs in humans.

Agreed...

There is no way I do anything but burn considerable calories and lose weight when engaging in sexual activity :p

I probably lose a pound or two in the process :p

An hour of intercourse burns 288 calories (for a 150 lb man). You'd have to engage in sex (actual intercourse) for (3500 / 288 =) 12 hours to burn even 1 lb of fat.

You people are just afraid of the truth.

This thing says orgasms make you fat. Sadly sex does not always equal orgasms.

It does if you're a man and you're not taking SSRIs...

In the majority of cases but not always...

Unless you are saying that not orgasming makes it not sex by definition?

I'm saying that -- for a man -- sex almost always results in an orgasm. Moreover, abstaining from orgasm increases testosterone, with peak increase seen around day 7. These factors (PRL and TEST) both correlate well to bodyfat levels -- where increasing PRL correlates positively, and increasing TEST correlates negatively.

For men (or women) who are trying to lose weight and/or build muscle, it would seem that sexual abstinence -- or at least abstaining from orgasm -- is an important consideration.

I guess this gives a whole new meaning to the term "fat fucker".
