Medicines can cause sexual problems in men and women in a number of ways. These include:
- a lack of sexual desire or interest in sex (libido)
- reduced ability to become physically aroused during sexual activity, including problems achieving and maintaining an erection (erectile dysfunction)
- delayed or absence of orgasm (climax)
- pain during intercourse (this mostly affects women)
- sustained erection lasting longer than 4 hours (priapism).
