Effects on Rat Sexual Behaviour of Acute MDMA (Ecstasy) Alone or in Combination with Loud Music

Thu, Dec 18, 2008 5:15 pm


Source: ncbi.nlm.nih.gov

 

The effects on sexual behaviour of acute low doses of methylendioxymethamphetamine (MDMA) (0.3, 1, 3 mg/kg/i.p.), alone or in combination with exposure to loud music (1 h stimulation), were investigated in Wistar rats. Results indicate that acute MDMA, at dose of 3 mg/kg, notably impaired copulatory behavior of sexually experienced male rats. In particular, MDMA-exposed animals exhibited a significant increase in intromission and ejaculation latencies as well as a significant decrease in percentage of rats displaying copulatory activity (one intromission at least). Surprisingly, one hour exposure to loud music, which per se resulted ineffective, antagonized the suppressive effect of MDMA by increasing the percent of animals displaying sexual activity. However, combined treatment of MDMA and music stimulation did not fully restore normal sexual behavior as the animals reaching ejaculation still showed a marked reduction of copulatory efficiency. These findings demonstrate that the systemic administration of a single low dose of MDMA, alone or in combination with loud music, which is commonly present in certain environments such as rave parties, notably impairs copulatory activity of male rats.

they are saying that the rats experience more sexual behavior but are unable to keep it up in combination with loud music

I'm sorry my bad .
I meant to say - Laboratories make rats out of marijuana and then put an X on them , which has been PROVEN to be safer than water in the lower 48 states during the winter months .
OK ? Get it now ?

Dude. What the fuck are you trying to say? Ecstasy turns rats into MJ, and those MJ-rat hybrids are safer to consume than water? Better lay off the meth and stick to the weed, man.

Drug users are incapable of being normal human beings. They belong in jail.

Except alcohol users.

awesome. that means that female rats at rave parties don't have to worry about humping male rats on ecstasy -- even if the beat is bumping.
