Advantages of the Progestogen-Only Pill (POP):
Highly effective: The typical-use failure rate is approximately 1 per 100 woman-years, similar to combined oral contraceptives (COCs). Effectiveness depends on strict adherence to timing, as the POP must be taken at the same time every day (within a 3-hour window for traditional POPs, extended to 12 hours for desogestrel-containing pills).
No interference with sexual activity: Unlike barrier methods, the POP does not require action at the time of intercourse, allowing spontaneity and no interruption during sex.
Reversible contraceptive effects: Fertility typically returns quickly after stopping the pill, often within weeks, making it suitable for women planning pregnancy in the near future.
Safe during breastfeeding: POPs do not affect milk production or composition. They are preferred over COCs in lactating women because oestrogens in COCs can reduce milk supply and potentially affect infant health.
Suitable when COCs are contraindicated: POPs are safe for women who smoke and are over 35 years old, those with a history of venous thromboembolism (VTE), hypertension, migraine with aura, or other conditions where oestrogen-containing contraceptives pose increased risk. This is because POPs lack oestrogen, which is primarily responsible for increased thrombotic risk.
