Assisted reproductive technology, IVF involves transfer of:

Correct answer: C. Zygote into the uterus

  • A. Ovum into the Fallopian tube
  • B. Zygote into the Fallopian tube
  • C. Zygote into the uterus
  • D. Embryo with 16 blastomeres into the Fallopian tube

Explanation

The correct answer is:c. Zygote into the uterusHere's an explanation of each option:a. Ovum into the Fallopian tube:This is not part of the IVF process. In IVF, the fertilization process takes place outside the body, typically in a laboratory setting, and the resulting embryo is then transferred into the uterus.b. Zygote into the Fallopian tube:This is not the standard IVF procedure. In traditional IVF, the fertilized egg (zygote) is transferred into the uterus, not the Fallopian tube. The purpose of IVF is to bypass potential issues related to the Fallopian tubes and allow fertilization to occur in vitro (outside the body).c. Zygote into the uterus:This is the correct procedure for IVF. After fertilization, the resulting zygote develops into an embryo, and the embryo is then transferred into the woman's uterus to establish a pregnancy.d. Embryo with 16 blastomeres into the Fallopian tube:This is not a part of the IVF process. In IVF, embryos are typically transferred directly into the uterus. The number of blastomeres is not as critical as the developmental stage when determining embryo transfer.Summary:In IVF, the transfer of a zygote (resulting from the fertilization of an egg and sperm) into the woman's uterus is a crucial step in the process. This allows for the establishment of a pregnancy, which is the primary goal of IVF. The correct answer is option c.

About Reproduction

Human reproduction covers the male and female reproductive organs, gamete formation, fertilization, implantation and hormonal regulation. The menstrual cycle includes ovarian and uterine changes controlled by pituitary and ovarian hormones, while sexually transmitted diseases are studied through their causes, transmission, symptoms, prevention and effects on fertility.
