Contraceptive Implant

 

How does it work?

​

The implant works by releasing the hormone progestin.

The implant prevents ovulation.

This is when the ovaries release an egg each month.

Progestin thickens the mucus in the cervix so sperm cannot easily pass through and it thins the lining of the womb (endometrium) which makes it difficult for the egg to implant itself.

How long does it last?

​

The contraceptive implant lasts for 3-5 years depending on the brand.
