Which Contraceptive Approach is Least Effective

Question

Which contraceptive approach is least effective?  
A) Abstinence
B) Tubal ligation
C) Vasectomy
D) Hormonal implant
E) Rhythm method

Accepted Answer

The rhythm method, also known as fertility awareness-based methods, relies on tracking a woman's menstrual cycle to determine when she is most and least likely to get pregnant. However, this method is only around 75% effective, making it the least reliable contraceptive approach. Other methods like hormonal implants and tubal ligation are over 99% effective when used correctly, and abstinence and vasectomy are also very effective when used consistently. It's essential to speak with a healthcare provider to determine which contraceptive method is best for an individual's needs and lifestyle.
