Enda et bevis på at verden er urettferdig.
Seksuell opphisselse gir høyere testosteronnivå hos både menn og kvinner (1). Men mens en høy orgasmefrekvens gir lavere testosteronnivå hos menn (2,3,4), så øker testosteronnivået direkte etter sex hos kvinner (5), och seksuelt aktive kvinner har høyere testosteronnivå (6).
Så gutter: skaff dere en luremus.
Jenter: ha mer sex.
1. "To determine whether changes in LH and testosterone (T) blood levels and pulse signals were induced by sexual arousal, nine healthy young males were presented on two different days with a sexually arousing (S) and a sexually neutral control (C) film. On both sessions, blood was sampled every 10 min for 12 hr. The Cluster and the Detect pulse identification algorithms were used to characterize the peaks in LH and T series. The second plasma LH peak following the beginning of the film was higher in the S than in the C condition (percent increases above preceding nadir: 322.1 +/- 183.9% vs. 202.6 +/- 108.7%). The area of the second pituitary peak of LH instantaneous secretion rate, which corresponded to the second plasma LH peak, was also greater in the S condition (6.2 +/- 3.3 vs. 3.4 +/- 2.3 UI/l). Compared with the C condition, T blood levels were increased within the first 10 min of sexual arousal (25.2 +/- 6.3 vs. 22.2 +/- 5.6 nmol/l). These results, consistent with the findings of animal studies, indicate that LH pulsatile secretion and T blood levels are influenced by changes in the state of sexual arousal in human males."

2. "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."

3. "The authors found that the fluctuations of testosterone levels from the 2nd to 5th day of abstinence were minimal. On the 7th day of abstinence, however, a clear peak of serum testosterone appeared, reaching 145.7% of the baseline"

4. "Twenty males participated in a 2-month study examining the relationship between 8 a.m. plasma testosterone levels and orgasmic frequency. Within subjects, higher levels of testosterone are associated with periods of sexual activity. Over subjects, however, the direction of the relationship is reversed. Mean testosterone levels were higher for sexually less active individuals."

5. "Orgasm induced elevations in cardiovascular parameters and levels of plasma adrenaline and noradrenaline. Plasma prolactin substantially increased after orgasm, remained elevated over the remainder of the session, and was still raised 60 minutes after sexual arousal. In addition, sexual arousal also produced small increases in plasma LH and testosterone concentrations. In contrast, plasma concentrations of cortisol, FSH, beta-endorphin, progesterone, and estradiol were unaffected by orgasm."
