Etonogestrel is used in the hormonal implant neplanon, which is inserted under the skin, and combined with oestrogen in the vaginal ring, which is a relatively new form of contraception.
Researchers have been exploring the use of etonogestrel as a form of male contraception1, and a hormonal coil containing etonogestrel was trialled in 2015, but was unsuccessful2.
How does it work?
Etonogestrel works in three ways: it prevents ovulation, changes your cervical fluid to stop sperm from entering your uterus, and changes the lining of your uterus so that a fertilised egg can’t implant3.
What is it in?
Is it androgenic?
No. (Check out our ‘Androgens’ blog for more info on what this means).
What are the side effects?
The side effects of etonogestrel are reported separately for the hormonal implant and the vaginal ring. To find out more about these visit the contraception pages on The Lowdown website.
