Askip la MD aussi réduit l'érection
MDMA
tends to prevent erection in a percentage of males. I do not know what the exact percentages are (there is no statistical data available for this that I am aware of). However, from the reports that I have read, it appears that erectile inhibition is experienced by the majority of males while taking MDMA. I have a feeling that this occurs as a result of MDMA's interaction with the serotonin receptors, and specifically with the 5HT1a, 5-HT1b, 5-HT1c and 5-HT2 receptor sites (5HT1a has specifically been suggested as the reason why patients taking SSRI anti-depressants experience erectile inhibition). I do not have any hard scientific data to back this up with respect to MDMA (again, I don't think that any studies of this kind exists), it is just a guess on my part.
