Diaphragm

Diaphragm

The diaphragm or cap is made of soft rubber with a flexible metal spring rim. It fits over the cervix and prevents entry of sperm. It is used with spermicidal cream or jelly. They vary in size and must be fitted by a well-trained doctor. Failure may be due to:
1.Improper fit.
2.Improper care.
3.Inconsistent use.
4.Slipping during intercourse due to;
a)Expansion of the vagina.
b)Cream on the rim,
c)Frequent, deep insertion of the penis.
d)Certain positions in which the penis may get in behind it.

The pregnancy rate with proper use is 2 - 4 %. Abstaining during about four days over ovulation increases its effectiveness.

Advantages:
1.No side effects if used properly.
2.No other effect than preventing pregnancy.
3.Non-disruptive to sexual activity.
4.Good for women who cannot or will not use the Pill or an I.U.D.
Disadvantages:
1.May find it hard to insert.
2.May be allergic to rubber or spermicides.
3.Cannot be used by:
a)women with a prolapsed uterus.
b)Women with a severely displaced uterus.
c)Virgins because the vagina is small.
