Match List-I with List-II:
| List-I | List-II |
|---|---|
| A. Amniocentesis | I. Correction of infertility due to very low sperm counts |
| B. Artificial insemination | II. Natural method of contraception |
| C. Progestasert | III. Detection of genetic disorders |
| D. Lactational amenorrhea | IV. Hormone-releasing IUD |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → A-III, B-I, C-IV, D-II
List-I mixes a test, a technique for infertility and two methods of contraception. Each one has a single use given in NCERT.
(A) Amniocentesis — this matches (III) Detection of genetic disorders. The fetal cells in a sample of amniotic fluid are tested for disorders such as Down syndrome.
(B) Artificial insemination — this matches (I) Correction of infertility due to very low sperm counts. Semen is introduced into the vagina or uterus artificially.
(C) Progestasert — this matches (IV) Hormone-releasing IUD. Progestasert and LNG-20 are hormone-releasing IUDs.
(D) Lactational amenorrhea — this matches (II) Natural method of contraception. It uses the absence of ovulation during intense breast-feeding, with no medicine or device.
So the correct matching is A-III, B-I, C-IV, D-II.
NCERT Extract:
Reproductive Health – Problems and Strategies – “… This procedure is used to test for the presence of certain genetic disorders such as, down syndrome, haemoplilia, sickle-cell anemia, etc., determine the survivability of the foetus.”
Population Stabilisation and Birth Control – “… and the hormone releasing IUDs (Progestasert, LNG-20) (Figure 3.2).”
Population Stabilisation and Birth Control – “… Lactational amenorrhea (absence of menstruation) method is based on the fact that ovulation and therefore the cycle do not occur during the period of intense lactation following parturition.”
Infertility – “… Infertility cases either due to inability of the male partner to inseminate the female or due to very low sperm counts in the ejaculates, could be corrected by artificial insemination (AI) technique.”
