Diaphragm / cap-with-spermicide
EFFECTIVENESS
Latex types are 92-96 per cent effective if used correctly. Between four and eight woman in 100 can fall pregnant in a year. Silicone caps are less effective.
HOW IT WORKS
A flexible latex or silicone device, used with spermicide, is put in the vagina to cover the cervix. This stops sperm from entering the uterus and meeting an egg.
