Implanon – Basics You Need to Know

Implanon is a hormonal implant containing only progesterone that is inserted subdermally into your arms. The progesterone released from it, thickens the uterine endometrium making it an unfavorable environment for the entrance of sperms.

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 basically a process by which, under the influence of the hormones estrogen and progesterone, the uterine lining is discharged when there’s an absence of fertilization.

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

  • It inhibits the release of the ovum from the ovary. Ovum is the female reproductive gamete that fuses which sperm of a male to form a zygote, the progeny to the fetus.
  • It thickens the uterine endometrium, this creates an adverse 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.
