One of the following is not a method of contraception. Which one?
- Pills of a combination of oxytocin and vasopressin
- Lippes loop
- Condoms
- Tubectomy
Answer
(1) Pills of a combination of oxytocin and vasopressin
Solution
As per NCERT, contraceptive methods include barrier methods (condoms), IUDs (non-medicated IUDs such as Lippes loop), oral pills and surgical methods (vasectomy, tubectomy).
⇒ Oral contraceptive pills contain progestogens or progestogen–estrogen combinations, which inhibit ovulation and implantation.
⇒ Oxytocin and vasopressin are posterior pituitary hormones (uterine contraction / milk ejection and water reabsorption) and are not used for contraception.
∴ Pills of a combination of oxytocin and vasopressin is not a method of contraception.
