Of all the scientific advancements, effective contraception is arguably the one that has been eminent in making women equal partners in society. It has also given men and women unprecedented control over such major life considerations as when and how families are created and reared.
One of the most successful means of contraception is the injectable contraceptive. This method of birth control involves synthetic hormones that are administered by a deep intra-muscular injection. These injections are considered to be a secure technique of reversible contraception for most women. There is availability of two types of injectable contraceptives. These are progestin-only contraceptives and combined contraceptives that contain both progestin and estrogen hormones. The progestin-only injections contain DMPA, which stands for depot medroxyprogesterone acetate. The administered dosage is 150 mg IM every three months. The injection should be given within the first five days of the onset of menses. If given beyond this time, it is advisable to use an alternate birth control method for two to four weeks.
The DMPA contraceptives prevent pregnancy by inhibiting the process of ovulation, which signifies the release of the eggs by the ovaries. They also thicken the cervical mucus, thus making it difficult for the sperms to pass through. This process also decreases the motility of the fallopian tubes. If found satisfactory, these injections can be used by women throughout their reproductive years. However, this method is recommended for females above the age of 16 because of the theoretical concern about its repercussion on bone density.
