Progestogen only contraception

Progestogen-only contraception is a type of hormonal contraception that uses only progestogen, a synthetic form of the naturally occurring hormone progesterone, to prevent pregnancy. This method of contraception is often chosen by women who cannot use estrogen-based contraceptives due to health reasons.

Types of Progestogen-only contraception

There are several types of progestogen-only contraception, including:

• Progestogen-only pill (POP): Also known as the "mini-pill," this is a daily oral contraceptive that thickens cervical mucus to prevent sperm from reaching the egg. Some types also stop ovulation.

• Progestogen-only injectable contraceptives: These are injections of progestogen, usually given every 12 weeks, that prevent ovulation and thicken cervical mucus.

• Progestogen implant: This is a small, flexible rod that is inserted under the skin of the upper arm. It releases progestogen and prevents ovulation for up to three years.

• Intrauterine system (IUS): This is a small device that is inserted into the uterus. It releases progestogen and can prevent pregnancy for up to five years.

Effectiveness

The effectiveness of progestogen-only contraception varies depending on the specific method used and how consistently and correctly it is used. When used perfectly, these methods can be over 99% effective at preventing pregnancy. However, typical use often results in lower effectiveness rates.

Side effects

Possible side effects of progestogen-only contraception can include changes in menstrual bleeding patterns, mood changes, and weight gain. However, these side effects are not experienced by all women and may decrease over time.

Benefits and risks

Progestogen-only contraception can be used by women who cannot use contraception that contains estrogen, such as those with certain health conditions or who are breastfeeding. It can also be used by women who are over 35 and smoke. However, it may not be suitable for women with a history of breast cancer or unexplained vaginal bleeding.
