Question

Which of the following is the least effective method of birth control?

• A. Skin implants
• B. Periodic abstinence
• C. Pills
• D. IUDs

Answer 1

The correct option is B Periodic abstinence

Periodic abstinence is a natural method of birth control, works based on the principle of avoiding chances of ovum meeting with the sperm.

Here, couples avoid or abstain from copulation between the 10th to the 17th day of the menstrual cycle during which ovulation is likely to happen.

Chances of fertilisation remain very high as the fertile period can vary in a woman due to extraneous factors like stress or diet.

Skin implants, pills and IUDs are efficient methods of contraception compared to the natural methods.
