The contraceptive injection is a shot of hormones – either a progestin alone, or a progestin and estrogen – that stop the ovaries from releasing eggs and thicken the cervical mucus to make it harder for sperm to move. It works much in the same way as other hormonal contraception methods, such as the pill, except one shot will have an effect for 1 or 3 months, depending on the type. This means, however, that its effects are not reversible once it has been administered.
Once you have decided that the contraceptive injection is right for you, your doctor or nurse will administer it. All you have to do is remember to return on time to get the next shot, either every month or every 3 months, to make sure the injection is at its most effective. If and when you want to return to fertility, it’s worth consulting your doctor or nurse as it may be some time before you can get pregnant.
Yes. The contraceptive injection contains hormones that are released throughout the entire body.
The contraceptive injection is effective for 3 months, but it’s important to get the shot on time to maintain its efficacy.
The contraceptive injection may cause irregular bleeding. In some cases it may cause shorter, lighter periods, or no periods at all.
Fertility may take up to a year to return after you stop having the contraceptive injection, depending on the type. However, the time it takes for periods and fertility to return to normal does vary from woman to woman.
If you are sexually active and find that this method of contraception works for you, you can continue having the injections every eight or thirteen weeks depending on the type.
Menstrual bleeding should not guide the injection schedule. The contraceptive injection should be administered every month or every eight to thirteen weeks, depending on the type, but this schedule is not dependent on menstruation.
Depending on the injection you receive, it lasts between eight and 13 weeks.
One of the potential side effects of the contraceptive injection is weight gain.
Male contraceptive injections have been developed but are still in the testing phases. Currently, the only birth control methods for men include condoms, abstinence, withdrawal, and/or a vasectomy.
