Infertility and Assisted Reproductive Technologies

Correct answer: A. Severe infection, heavy bleeding, and a life-threatening condition.

Explanation: An unsafe MTP may involve unhygienic conditions, inappropriate techniques, or an untrained provider. These circumstances can cause severe infection, heavy bleeding, injury, or other complications that may become life-threatening. Therefore, option A identifies the most serious potential risk.

Correct answer: A. Because causes may be related to the male partner, the female partner, or both.

Explanation: Infertility is a reproductive-health condition that can arise from male factors, female factors, or a combination of both. Reduced sperm count or motility, ovulation disorders, and blocked fallopian tubes are examples. Therefore, evaluating both partners improves diagnostic accuracy and guides suitable treatment; blaming only one partner is scientifically unjustified.

Correct answer: A. To help couples affected by infertility achieve pregnancy by assisting fertilisation, gamete transfer, or embryo transfer

Explanation: Assisted reproductive technology is primarily used to help people affected by infertility achieve pregnancy. Depending on the procedure, it may assist fertilisation or involve the transfer of gametes or an embryo. Permanent contraception, vaccination, and treatment only with hormones are not the primary purposes of ART.

Correct answer: A. Outside the body under controlled laboratory conditions

Explanation: IVF means in vitro fertilisation, so the ovum and sperm are brought together outside the body under controlled laboratory conditions. After fertilisation and early development, the resulting embryo is transferred to the uterus. Fertilisation in the fallopian tube occurs in normal conception, not in IVF.

Correct answer: A. The embryo formed in the laboratory must be placed in the uterus for implantation and further development

Explanation: In IVF-ET, fertilisation takes place outside the body, but the embryo needs a suitable uterus for implantation and continued development. Therefore, it is transferred to the uterus. Destroying sperm, using a condom, and cutting the vas deferens are contraceptive measures, not steps in embryo transfer.

Correct answer: A. The site where the embryo or zygote is transferred

Explanation: In both ZIFT and IUT, fertilisation occurs outside the body. In ZIFT, a zygote or very early embryo is transferred into a fallopian tube, whereas in IUT, an embryo is transferred into the uterus. Thus, the key difference is the site of transfer, not the site of fertilisation.

Correct answer: A. When a woman cannot produce ova but has functional fallopian tubes and a donor ovum is available

Explanation: GIFT, or gamete intrafallopian transfer, may help a woman who cannot produce ova if her fallopian tubes are functional. Donor ova and sperm are placed in the fallopian tube so that fertilisation can occur inside the body. Option B describes ICSI, option C describes IVF-ET, and option D describes vasectomy.

Correct answer: A. A selected sperm is injected directly into the cytoplasm of a mature oocyte.

Explanation: In ICSI, a single selected sperm is injected directly into the cytoplasm of a mature oocyte using micromanipulation. This provides direct control over the sperm used for fertilisation. In conventional IVF, many sperm are placed around the oocyte and fertilisation occurs without injecting an individual sperm.

Correct answer: A. To increase the chance of fertilisation

Explanation: In intrauterine insemination, processed sperm are placed in the uterus around the time of ovulation. This can reduce the distance sperm must travel and increase the likelihood that sperm will meet the oocyte. IUI is not intended to stop ovulation or terminate a pregnancy.

Correct answer: A. To assist fertilisation or conception in cases of infertility

Explanation: Donor sperm or donor oocytes may be used in assisted reproduction when a person or couple cannot use suitable gametes of their own, or when donor gametes are medically indicated. They can help achieve fertilisation and pregnancy, but they are not contraceptives, infection treatments, or direct ovulation-inducing agents.

Correct answer: A. The underlying cause is evaluated first, and less invasive or cause-specific treatments may be effective.

Explanation: Infertility management begins with assessment of possible causes, such as ovulation problems, tubal factors, infections, hormonal conditions, or male-factor infertility. Medicines, lifestyle changes, or cause-specific treatment may help in some cases and may be less invasive than ART. ART is selected when medically appropriate, not automatically as the first step.

Correct answer: A. IUI — transferring processed semen or sperm into the uterus

Explanation: IUI means intrauterine insemination, in which processed semen or sperm is placed in the uterus rather than directly into a fallopian tube. GIFT transfers gametes into a fallopian tube, IVF involves fertilisation outside the body, and ICSI injects one sperm into an oocyte.

Correct answer: A. When the couple's own suitable gametes are unavailable or unsuitable for fertilisation

Explanation: The governing concept is treatment of infertility through assisted reproduction. Donor sperm or donor ova may be considered when one or both partners cannot provide viable, suitable gametes because of absent gametes, severe gamete dysfunction, or another clinically indicated problem. Contraception prevents pregnancy and infection requires medical treatment; neither calls for donor gametes. Non-medical sex selection is also not an appropriate indication. Hence option A is correct.
