Implanon – Basics You Need to Know

Implanon is a hormonal implant containing only progesterone inserted into your arms. It is inserted subdermally, which is right underneath your skin. The progesterone hormone thickens the mucous of the cervix making it difficult for sperm to pass through.

Progesterone also thins out the mucous of the body of the uterus. This is where the implantation of the fetus normally takes place. So, on the off chance that sperm does manage to fertilize the ovum, the implantation can’t happen.

Naturally, the main focus for placing IUD is, “ when can I have unprotected sex after getting Implanon?”. It’s important to know that the released hormone will take about a week to perform its function. So, precautions should be exercised during this period.

How is Implanon Inserted?

Implanon is subdermally placed in your arms. Before the procedure, you will have to undergo a pregnancy test. The doctor may also perform a physical examination to ensure your body is ready for the strain.

After the initial examinations, your doctor will create an aseptic environment by cleaning your arm area. Then they will insert the Implanon with an applicator. You will feel some pressure and discomfort in the area after the placement of the Implanon.

The doctor will place a bandage over the site of insertion. Regarding this bandage, one question comes to mind, ‘how long do you have to keep a bandage on after the implant?’ The answer to that is anywhere between one to five days. You should contact with your physician if you have pain, bleeding or the wound doesn’t heal within five days.

How does Implanon Work?

It’s necessary to know a bit about fertilization and the menstrual cycle before you dive into how Implanon prevents pregnancy. The menstrual cycle is a process by which the uterine lining is discharged when there’s no fertilization. This happens under the influence of the hormones estrogen and progesterone,

And, fertilization is the process by which the female gamete ovum and male gamete sperm, fuse together to form the zygote. This zygote divides and grows to be the fetus later on.

Now, Implanons are implants that contain only progesterone. Progesterone as you know is one of the two hormones responsible for menstruation and female fertility. Implanon acts on pregnancy in two ways:

  • It inhibits the release of the ovum from the ovary. Ovum is the female reproductive gamete cell or in simple terms, the ‘egg cell’. This fuses which sperm of a male to form a zygote.
  • It thickens the uterine endometrium. This creates a hostile environment for male sperms, so they cannot enter or survive.

As you may have guessed, it probably requires some time for the Implanon to cause the hormonal changes necessary for the prevention of fertilization and pregnancy. 

So while thinking about when can I have unprotected sex after getting Implanon, you must take these parameters into consideration.
