Lecture Notes

A diaphragm is a rubber cup with a flexible rim that is placed deep inside the vagina, blocking the cervix, to prevent sperm from entering the uterus and the fallopian tubes. Somewhat effective by itself, the diaphragm is highly effective when used with a spermicidal jelly or cream.<br />

After intercourse, it should be left in place for at least 6 hours. If intercourse is repeated within 6 hours, the diaphragm should be left in place and more spermicide inserted with an applicator. To remove a diaphragm, the woman inserts a finger into her vagina and under the front of the diaphragm rim and then gently pulls it out. A diaphragm is available by prescription only and should be replaced about once a year.

The advantages includes that it helps protect against STIs of the cervix and pelvic inflammatory disease, but it has numerous disadvantages. Women dislike the process of insertion and the mess or smell of chemical contraceptives that are used with the diaphragm.

Men complain of rubbing and other discomfort, and individuals can have an allergic reaction. There's also increased risk for urinary tract infections and the risk of toxic shock syndrome. Also, the diaphragm is assumed not to protect against HIV.
