Schneider MP, et al. - Among adolescent and young adult women (AYA) diagnosed with endometriosis, researchers quantified the prevalence of dyspareunia, defined as answering “yes” to having had pain during/within 24 hours following sexual intercourse, and its impact on quality of life (QOL). Participants in the study were AYA with a surgical diagnosis of endometriosis (n = 151) and without known endometriosis (n = 287). According to findings, more than three-quarters of AYA with endometriosis and two-thirds without reported dyspareunia that has a negative effect on QOL ratings for both physical and mental wellbeing. In those with endometriosis, this impairment is stronger. Due to the importance of relationships and peer engagement in the formation of identity during adolescence, dyspareunia may have a particular impact. Physicians should not only ask patients about contraception and prevention of sexually transmitted infections, but should also investigate how dyspareunia can affect mental and physical well-being.
