Abstract: | 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. |
