Reproductive Health

Given below are four methods (1-4) and their modes of action (a-d) in achieving contraception. Select their correct matching from the four options that follow:

1. 1 = (b), 2 = (c), 3 = (a), 4 = (d)
2. 1 = (c), 2 = (d), 3 = (a), 4 = (b)
3. 1 = (c), 2 = (a), 3 = (d), 4 = (b)
4. 1 = (d), 2 = (a), 3 = (b), 4 = (c)

Answer

(3) 1 = (c), 2 = (a), 3 = (d), 4 = (b)

Solution

(1) Oral pills (progestogens or progestogen–oestrogen combinations) inhibit ovulation ⇒ 1 = (c).

(2) Condom is a barrier that prevents the sperms from reaching the cervix ⇒ 2 = (a).

(3) Vasectomy cuts and ties the vasa deferentia, so the semen contains no sperms ⇒ 3 = (d).

(4) Copper-T increases phagocytosis of sperms and makes the uterus unsuitable for implantation ⇒ 4 = (b).

∴ 1 = (c), 2 = (a), 3 = (d), 4 = (b).

Answer: (3)
