| List-I | List-II |
|---|---|
| (a) Diaphragms | (i) Inhibit ovulation and Implantation |
| (b) Contraceptive Pills | (ii) Increase phagocytosis of sperm within Uterus |
| (c) Intra Uterine Devices | (iii) Absence of Menstrual cycle and ovulation following parturition |
| (d) Lactational Amenorrhea | (iv) They cover the cervix blocking the entry of sperms |
Choose the correct answer from the options given below:
(1) (a) – (ii), (b) – (iv), (c) – (i), (d) – (iii)
(2) (a) – (iii), (b) – (ii), (c) – (i), (d) – (iv)
(3) (a) – (iv), (b) – (i), (c) – (iii), (d) – (ii)
(4) (a) – (iv), (b) – (i), (c) – (ii), (d) – (iii)
Answer: Option (4)
Explanation:
Diaphragms are barrier methods of contraception that cover the cervix and prevent the entry of sperms into the uterus.
Hence, Diaphragms correspond to blocking the entry of sperms.
Contraceptive pills contain hormones that inhibit ovulation and also prevent implantation.
Thus, Contraceptive pills correspond to inhibition of ovulation and implantation.
Intra uterine devices increase phagocytosis of sperms within the uterus and also reduce their motility.
Therefore, Intra uterine devices correspond to increased phagocytosis of sperms.
Lactational amenorrhea refers to the absence of menstrual cycle and ovulation following childbirth due to hormonal changes during breastfeeding.
Thus, Lactational amenorrhea corresponds to absence of menstrual cycle and ovulation following parturition.
Hence, the correct matching is (a) – (iv), (b) – (i), (c) – (ii), (d) – (iii).
