what is diaphragm? work of it?
Answers
Answer:
A diaphragm is a dome-shaped bowl made of thin, flexible silicone that sits over the cervix, the part of the uterus that opens into the vagina. It covers the cervix so sperm can't get in and fertilize an egg.
How Does a Diaphragm Work?
A diaphragm keeps sperm from entering the uterus by covering the cervix. For added protection, spermicide is put into the bowl of the diaphragm and along its edges before it's inserted. The diaphragm is placed high into the vagina so it covers the cervix.
The diaphragm can be put in up to 2 hours before having sex, and must be left in place at least 6 hours after sex. The diaphragm should not stay in longer than 24 hours. More spermicide must be used each time a young woman has sex while wearing the diaphragm.
How Well Does a Diaphragm Work?
Over the course of a year, 12 out of 100 typical couples who use the diaphragm with spermicide will have an accidental pregnancy.
How well the diaphragm works depends on:
how well it fits
whether a couple uses it every time they have sex
whether spermicide is used appropriately
A diaphragm also needs to be cared for. After each use, it must be washed (with mild soap and water), rinsed, and air dried, then stored in its case. Don't put baby powder or oil-based lubricants (such as mineral oil, petroleum jelly, or baby oil) on the diaphragm. Other vaginal creams, such as yeast infection medicines, also can damage the diaphragm.
