Contraception
Helping your patients make the right choice
With rising abortion rates, particularly among all ages 22 and above, over the last 10 years, the largest increase are amongst women aged 30-34. Therefore, there is a clear need to offer the most effective contraceptive methods. In a quantitative survey of over 430 women and their experiences of unintended pregnancy and abortion, over half were using contraception at the time they became pregnant. Long-acting methods can be the most effective form of contraception because they do not rely on user compliance.
Pill compliance is a common struggle for women
For every 100 women that choose to take the pill this year, nine could become pregnant due to missed-pill moments.
Long-acting methods such as intrauterine systems (IUS) offer birth control with the highest available efficacy and are one of the most effective contraceptive methods because their effectiveness is independent of user compliance.
