Contraceptive Diaphragm

Contraceptive diaphragm is a contraceptive device fitted over the uterine cervix to block sperm. It is a flexible dome-shaped rubber or plastic cup filled with spermicide. It is put in place prior to intercourse and left in place for six hours or more after coitus. However, it should not remain for more than 24 hours or it could lead to toxic shock syndrome. The typical use failure rate is about 17%. It also does not provide full protection against sexually transmitted infections. Possible side effects are increased risk of bacterial vaginosis and urinary tract infections. Nevertheless, it is still included in the World Health Organization’s List of Essential Medicines for its advantages over other contraceptive methods. For instance, it does not interfere with the woman’s natural cycle. It is also the method of choice by women who are not frequently engaged in sexual intercourse. The diaphragm is also less expensive than the other contraceptives. Synonym: cervical cap.
