Introduction
Newer contraceptive methods have been developed to provide effective pregnancy prevention while also offering additional health benefits and minimizing risks. These methods include oral contraceptives, implantable devices, and alternative hormonal delivery systems. Understanding the risks and benefits associated with these newer contraceptive methods is crucial for informed decision-making.
Key Insights
Benefits
- Efficacy and Safety: Modern low-dose oral contraceptives are highly effective and relatively safe, reducing the need for abortion or surgical sterilization .
- Cancer Risk Reduction: Oral contraceptives and combined hormonal contraceptives reduce the risk of endometrial and ovarian cancer .
- Menstrual Regulation: These contraceptives improve menstrual regularity, reduce dysmenorrhea, and decrease menstrual blood flow .
- Non-Contraceptive Health Benefits: Combined hormonal contraceptives can improve acne, hirsutism, and bone mineral density, and may offer protection against pelvic inflammatory disease .
- Convenience and Adherence: Newer delivery systems like vaginal rings, transdermal patches, and implants offer greater convenience and require less frequent adherence, which can improve continuation rates .
- Specific Benefits for Older Women: New combined hormonal contraceptives (CHC) are particularly beneficial for women over 40, helping with menstrual disorders and potentially alleviating cardiovascular disease and depression.
Risks
- Cardiovascular Risks: Oral contraceptives, especially those containing third-generation progestogens, are associated with an increased risk of venous thromboembolism and arterial thrombosis, particularly in women who smoke, have hypertension, or are over 35 years old .
- Bleeding Disturbances: Implantable contraceptives are commonly associated with bleeding disturbances, which can be a significant side effect for many users.
- Cancer Risks: There is a possible small increase in the risk of breast and cervical cancer with the use of hormonal contraceptives, and an increased risk of liver cancer .
- Insertion and Removal Risks: Implantable contraceptives require trained providers for insertion and removal, which can pose minor risks and may lead to issues with access or coercion.
Conclusion
Newer contraceptive methods offer significant benefits, including high efficacy, improved menstrual regulation, and reduced risks of certain cancers. They also provide non-contraceptive health benefits such as improved acne and bone density. However, these methods are not without risks, particularly cardiovascular risks and bleeding disturbances. The choice of contraceptive method should be tailored to individual health profiles and lifestyle factors to maximize benefits and minimize risks.
