Facts about depo provera

provera
The most common injectable hormonal contraceptive is Depo-Provera, a synthetic hormonal substance also known as DMPA (depot-medroxyprogesterone acetate) that is injected into the muscle in the upper arm or buttocks every three months.
Another, shorter-acting injectable hormone, norethdrone enanthate, is injected at a higher dose every two months.
Injectable hormones prevent pregnancy by suppressing ovulation; by making it more difficult for the sperm to swim through the cervical mucus; and by destroying the endometrial lining of the uterus, keeping fertilised eggs from implanting.
DMPA is a safe and highly effective contraceptive.
The success rate for women using DMPA is 99.7 percent.
It reduces menstrual cramps, iron-deficiency anaemia, and the risk for endometrial cancer.
A disadvantage of DMPA is that it requires visits to the doctor or other health care professional every 3 months.
