Reproductive Health practice questions with answers

1. Q1Multiple choice·1 mark
   Transfer of an ovum collected from a donor into the fallopian tube of another female who cannot produce one, but can provide a suitable environment for fertilization and further development, is referred to as:

   1. (a)GIFT
   2. (b)ZIFT
   3. (c)ICSI
   4. (d)IUT
   Show answer and step marks

   1. Correct option: (a) $GIFT$ (Gamete Intrafallopian Transfer). It involves transferring an ovum from a donor into the fallopian tube of a recipient who cannot produce ova but can provide fertilization and gestation.+1

   Answer: (a)
2. Q2Multiple choice·1 mark
   Which of the following is a hormone-releasing intrauterine device (IUD)?

   1. (a)CuT
   2. (b)Multiload 375
   3. (c)LNG-20
   4. (d)Lippes loop
   Show answer and step marks

   1. Correct option: (c) $LNG-20$. LNG-20 releases hormones (progestogens) that make the uterus unsuitable for implantation and the cervix hostile to sperms, whereas CuT and Multiload 375 release copper ions, and Lippes loop is a non-medicated IUD.+1

   Answer: (c)
3. Q3Short answer·3 marks
   Briefly explain any three Assisted Reproductive Technologies (ART) used to help infertile couples have children.
   Show answer and step marks

   1. First ART, any one of: In Vitro Fertilisation followed by Embryo Transfer (IVF-ET, test tube baby): ova and sperm are fused in the laboratory to form a zygote, which (or an early embryo up to 8 blastomeres) is transferred into the fallopian tube (ZIFT), while embryos with more than 8 blastomeres are transferred into the uterus (IUT); ZIFT and IUT may be credited as separate techniques; Gamete Intra Fallopian Transfer (GIFT): an ovum collected from a donor is transferred, with sperm, into the fallopian tube of a woman who cannot produce ova but can provide suitable conditions for fertilisation and development; Intracytoplasmic Sperm Injection (ICSI): a single sperm is injected directly into the cytoplasm of the ovum in the laboratory to form an embryo; Artificial Insemination (AI) or Intra-Uterine Insemination (IUI): semen from the husband or a donor is artificially introduced into the vagina or uterus, used when the male cannot inseminate or has a very low sperm count; or any other valid assisted reproductive technology.+1
   2. Second ART, a different one from the same list.+1
   3. Third ART, a different one from the same list.+1

   Answer: Any three of: IVF-ET, where ova and sperm are fused in the lab and the zygote/early embryo (up to 8 blastomeres) is placed in the fallopian tube (ZIFT) or a later embryo in the uterus (IUT); GIFT, where a donor ovum is placed with sperm in the fallopian tube of a woman who cannot produce ova; ICSI, where a sperm is injected directly into the ovum; AI/IUI, where semen from the husband or a donor is introduced into the vagina or uterus.
4. Q4Short answer·3 marks
   Define infertility. Describe the steps involved in In Vitro Fertilization (IVF) followed by Embryo Transfer (ET) as an Assisted Reproductive Technology.
   Show answer and step marks

   1. Definition: Infertility is the inability to produce children despite unprotected sexual cohabitation.+1
   2. In Vitro Fertilization (IVF): ova from the wife or a donor and sperm from the husband or a donor are collected and fused under simulated laboratory conditions to form a zygote.+1
   3. ZIFT: the zygote or early embryo with up to 8 blastomeres is transferred into the fallopian tube.+0.5
   4. IUT: an embryo with more than 8 blastomeres is transferred into the uterus.+0.5

   Answer: Infertility is the inability to produce children despite unprotected sexual cohabitation. In IVF, ova and sperm are collected and fused in the laboratory to form a zygote; the zygote or early embryo (up to 8 blastomeres) is then transferred into the fallopian tube (ZIFT), or an embryo with more than 8 blastomeres into the uterus (IUT).
