The Causes
What causes premature ejaculation (PE)?
In the past PE was thought to be purely psychological. Now doctors know PE can have a physical cause as it is associated with serotonin signals in the brain (like a brain messenger chemical) that control ejaculation.
Further knowledge about PE continues to increase. Scientists discovered variations in a gene controlling serotonin signalling that could be linked to PE and some drug treatments used for treating PE works by influencing the serotonin signalling pathway.
