The study, led by the Queensland University of Technology in Brisbane, Australia, found men can experience postcoital dysphoria, a term used to describe negative feelings, like irritation or anxiety, experienced by people after sex. Researchers analyzed the responses of more than 1,200 men to an online survey, which asked them if they had ever experienced symptoms of PCD after consensual and satisfactory intercourses. The results showed 41 percent of men reported experiencing PCD in their lifetime and 20 percent reported experiencing it in the previous four weeks. The study, published in the Journal of Sex & Marital Therapy, found PCD was associated with psychological disorders, sexual health problems and sexual abuse experienced in childhood. More than 200 women aged 18 to 55 were asked to take part in a survey about their experiences of PCD. Of those polled, 46 percent said they had experienced PCD in the past and around five percent said they had experienced the symptoms over the previous month.
