Post-coital tristesse

Post-coital tristesse (PCT) is the feeling of sadness, anxiety, agitation or aggression after sexual intercourse, mostly in males. Its name comes from New Latin postcoitalis and French tristesse, literally "sadness". Many people with PCT may exhibit strong feelings of anxiety lasting from five minutes to two hours after coitus.[1]

The phenomenon was first mentioned by the Greek doctor Galen, who wrote that "Every animal is sad after coitus except the human female and the rooster."[2] The philosopher Baruch Spinoza, in his Tractatus de Intellectus Emendatione, wrote: "For as far as sensual pleasure is concerned, the mind is so caught up in it, as if at peace in a [true] good, that it is quite prevented from thinking of anything else. But after the enjoyment of sensual pleasure is passed, the greatest sadness follows. If this does not completely engross, still it thoroughly confuses and dulls the mind."

One study reported that among a sample of 1208 male participants, 40% of them had experienced PCT at least once in their lifetime and 20% reported experiencing PCT in the four weeks preceding the study. This study also reports that 3-4% of the sample experienced PCT symptoms on a regular basis. According to the same study, PCT among males is associated with current psychological distress, sexual abuse during childhood, and with several sexual dysfunctions.[3]

With respect to symptoms in women, one study involved an epidemiological survey of post-coital psychological symptoms in a United Kingdom population sample of female twins: it found that 3.7% of women reported suffering from recent PCT and 7.7% suffering PCT for a long time.[4] Another study reported that almost half of female university students reported PCT symptoms at least once in their lifetime. The study also reported that there appeared to be no correlation between PCT and intimacy in close relationships.[5]
