How Contraception Injections Work
Contraceptive injections are one of the simplest forms of contraception available today. One of the main reasons why many women choose to have an injection is because they are free on the NHS. So if you’re on a budget and you are worried about the cost of contraception, you needn’t be with this method.
They are also one of the quickest, painless and long lasting forms of contraception that you can use. The question is how do they work?
Understanding Contraceptive Injections
There are two types of contraceptive injections that you can choose from. One lasts slightly longer than the other one and they both contain Progestogen. It is injected into the muscle and the progestogen stops the ovaries from releasing an egg every month. It also works by thickening the mucus that is found in the cervix. This in turn will make it much more difficult for the sperm to reach the egg. The lining of the womb also becomes thinner which makes it less likely to accept a fertilised egg. It’s worth pointing out that it won’t always stop an egg from being released.
So as you can see, the fact that the injections work in three different ways means that they are very effective in stopping you from getting pregnant. They have over a 99% effectiveness rating. The injections are usually given in the bottom, though if you are having Depo-Provera injections it can also be given in the leg or your arm sometimes.
There are a few myths surrounding the contraceptive injection. Firstly it is believed that they can cause you to become infertile. This isn’t true. However, it can make it extremely difficult for you to conceive for 12 months after you stop the injections. After that though, you should find that you can start a family as normal. Another common myth is that you can only use this type of contraception for two years. As long as you do not have any risk factors of osteoporosis, you can safely use the contraceptive injection for longer than this.
The injections will be given by your GP usually at your local doctor’s surgery. You can always make an appointment beforehand for a medical assessment to check you are healthy and that you know everything there is to know about the procedure before you have it done. They will be able to talk you through the potential side effects that you could suffer with.
