Gestodene is like that friend who never wants to go anywhere on their own; a third-generation synthetic progestin, it’s almost always used in the Combined Pill alongside synthetic oestrogens.
Gestodene is thought to have no or weak androgenic activity, so it’s often recommended for use by people who prefer a less-androgenic contraceptive1. In some countries, it’s also used as a form of Hormone Replacement Therapy (HRT).
How does it work?
Gestodene stops you from ovulating. When it’s used alongside Ethinyl Estradiol (a synthetic oestrogen) it also makes your cervical fluid too thick for sperm to pass through, and makes your uterine lining too thin for a fertilised egg to implant.
What is it used in?
Is it androgenic?
Yes, but it is weak1.
What are the side effects?
As Gestodene is only used in combined contraceptives with Ethinyl Estradiol (synthetic oestrogen), it’s hard to say which of the reported side effects it is responsible for, and which are down to its fellow hormone. When Gestodene is used alongside Ethinyl Estradiol, the following side effects have been reported2:
- Abdominal pain
- Breast abnormalities
- Increased risk of infection
- Irregularities of the menstrual cycle
- Mood swings
- Increased vaginal discharge
