Progestogen-only contraceptive methods do not contain oestrogen. Therefore, they are safer than combined oral contraceptive pills and can be used, if you have cardiovascular risk factors.
Progestogen-only preparations are:
- Progestogen-only pills (mini-pills/POP)
- Progestogen injections
- Subdermal implants
- Hormone-releasing intrauterine system
Progestogen-only contraceptive methods are safe,
- If the woman is a breastfeeding mother.
- If the woman is older.
- If the woman has cardiovascular risk factors.
- If the woman has diabetes.
How do progestogen-only preparations act?
Progestogen hormones act on the cervix and the lining of the womb (endometrium). They change the cervical secretions, making the cervix hostile to moving sperms from the vagina. These hormones inhibit the development of the endometrium, thereby preventing implantation and sperm movement. Higher dose preparations can inhibit ovulation too.
Adverse effects of progestogen-only contraceptive methods
The common side effects include:
- Breast pain
- Pimples (acne)
- Functional ovarian cysts
- Absent menstrual cycles
