Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A)-(IV), (B)-(I), (C)-(II), (D)-(III)
(A) Diaphragms — this matches (IV) They cover the cervix blocking the entry of sperms. Diaphragms, cervical caps and vaults are rubber barriers placed in the female tract during coitus.
(B) Contraceptive pills — this matches (I) Inhibit ovulation and implantation. These progestogen or progestogen-estrogen pills stop ovulation and implantation and make the cervical mucus hostile to sperms.
(C) Intra Uterine Devices — this matches (II) Increase phagocytosis of sperm within uterus. IUDs increase phagocytosis of sperms in the uterus; copper ions also lower sperm motility.
(D) Lactational amenorrhea — this matches (III) Absence of menstrual cycle and ovulation following parturition. During intense breast-feeding after delivery, ovulation and the cycle do not occur.
