Perceived ejaculate volume reduction (PEVR) is a condition in which a man appears to ejaculate less semen, whether suddenly or over an observable period of time. This can be a distressing source of sexual frustration and may also be a sign of low testosterone production. Scientists are now beginning to establish a link between erectile dysfunction (ED) and PEVR, with many men experiencing both sexual disorders simultaneously.

As the name suggests, perceived ejaculate volume reduction is often a subjective experience, so treatment may not always be strictly medical. Sex therapy and making alterations to intimate connections can be useful tools in offsetting the emotional barriers created by PEVR.

A 2015 study by the International Society for Sexual Medicine focused on a group of 988 men who were being screened for potential testosterone therapy.
