1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. None is correct
2. Only II is correct
3. Both I and II are correct
4. None is correct
In ZIFT:
| I: | As in IVF and GIFT, ZIFT involves ovarian stimu-lation, monitoring and egg retrieval. |
| II: | Sperm are collected, specially processed and used to fertilize the egg in vitro. |
| III: |
If fertilization takes place, those eggs that have been fertilized (thus becoming zygotes) are transferred into the fallopian tubes rather than the uterus. |
1. I, II, III are correct
2. I and II are correct
3. I and III are correct
4. II and III are correct
ZIFT is considered better than gift because:
| 1. | ZIFT is an easier technique |
| 2. | In ZIFT fertilization is ensured |
| 3. | ZIFT is less expensive than GIFT |
| 4. | ZIFT is a readily available technique |
Which is not correct about GIFT?
| 1. | Eggs are removed from a woman’s ovaries, and placed in one of the fallopian tubes, along with the man’s sperm. |
| 2. | The primary distinction between GIFT and IVF isthat with GIFT fertilization occurs naturally within the woman’s body instead of in the laboratory. |
| 3. | Females with both her fallopian tubes blocked can be benefited by GIFT |
| 4. | In terms of deliveries per retrieval, GIFT has a higher success rate than IVF regardless of a woman’s age. |
In vitro fertilization (IVF) is a four-stage procedure. The correct sequence is:
| I: | Egg (oocyte) retrieval |
| II: | Ovarian stimulation and monitoring |
| III: | Fertilization |
| IV: | Embryo transfer |
1. I, II, III, IV
2. IV, III, II, I
3. II, III, I, IV
4. II, I, III, IV
Artificial insemination is not effective in cases where:
| I: | The female has both her fallopian tubes blocked. |
| II: | The female has ovarian failure |
1. Both are correct
2. Only I is correct
3. Only II is correct
4. Both are incorrect
Consider the following statements regarding “Saheli”:
| I: | CDRI, Lucknow has developed the molecule, cent-chroman, marketed as “Saheli” |
| II: | It has the distinction of being the world’s first non steroidal oral contraceptive pill |
| III: | It inhibits the nidation of the fertilized ovum and thus prevents pregnancy |
The correct statement are:
1. I and II
2. I and III
3. II and III
4. I, II, III
The search for male contraceptive pill is going on but identify which of the following are true:
| I: | Pills made from gossypol, a compound found in cotton seeds and okra, have been abandoned as potential male contraceptive because the compound was proven to cause permanent infertility. |
| II: | Tests were performed on male rats using oleanolic acid, extracted from Eugenia jambolana, a tree in the southern part of Africa. The tests demonstrated that the chemical was found to reversibly lower the rats’ sperm motility without affecting the sperm count. |
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
In Which of the following techniques, the embryos are transferred to assist those females who cannot conceive?
| 1. | GIFT and ZIFT | 2. | ICSI and ZIFT |
| 3. | GIFT and ICSI | 4. | ZIFT and IUT |
