Half of men who illicitly use amphetamines report that the drugs have a negative impact on sexual function, with the nature of the effect varying between users, report Taiwanese researchers.
The team found that amphetamines, including amphetamine, methamphetamine, methylphenidate, and 3,4-methylenedioxymethamphetamine (MDMA, ‘Ecstasy’), reduced erectile rigidity and sexual satisfaction, enhanced orgasmic intensity, and delayed ejaculation.
However, just as many men reported increased sexual desire as reported reduced desire, the findings reveal, which indicates that dosing frequency has more of an impact than duration of use.
“Illicit use of amphetamine has disparate effects on users’ sexual functions, and the users have reported either enhanced or deleterious impact of it on sexual desire, erectile function, orgasmic intensity, ejaculation latency time, and sexual life satisfaction,” the investigators write.
“The dosing frequency of amphetamine had some association with its impact on sexual functions, while duration of drug use had little association,” they add.
