Diaphragm is one of the reliable birth control devices to prevent the unplanned pregnancy. It can also help to protect against certain sexually transmitted diseases. It is an affordable and comfortable option that can be washed and reused. It acts as a barrier to resist the sperms from entering the uterus.
Diaphragm is a shallow rubber disk with a dome-shape having a flexible rim. It can be introduced into the vagina and it effectively covers the cervix. A diaphragm, if used with spermicides can be a very effective birth control. It can be obtained by the prescription of doctor. It should be properly fitted by the doctor, as improperly fitted diaphragm can cause pregnancy. During the pelvic examination, the vagina is measured and then the size of diaphragm is decided. The diaphragm can be kept for 24 hours. However, it is necessary to insert the spermicide every two hours or at the time of intercourse. Do no remove the diaphragm at least for 6 hours after the sexual intercourse.
The diaphragm blocks the cervix and prevents the entry of sperms into the uterus. The spermicide immobilizes and kills the sperms and prevents them to fertilize the egg. The diaphragm can offer the protection against some sexually transmitted diseases like Chlamydia and gonorrhea. But, it can not protect against others including herpes and HIV. When use perfectly, it is more than 91% effective to prevent the pregnancy.
The main advantage of using diaphragm is that it does not affect the menstrual cycle or future fertility. It is reusable and inexpensive. When placed properly, the diaphragm is not felt by the partner.
If the diaphragm is left in the vagina for more than 24 hours, there may be a risk of toxic shock syndrome (TSS). Some women may have mild allergic reactions to the spermicide or rubber.
