Question

Embryo with more than 16 blastomere formed due to in vitro fertilization is transferred into
A. Cervix
B. Uterus
C. Fallopian tube
D. Fimbriae

Answer 1

Hint: If the zygote or early embryo transfers to the fallopian tube then it’s called Zygote intra fallopian tube. Embryo with more than 8 blastomere is transferred into the uterus is called Intrauterine transfer.

Complete answer:
This technique is known as IVF in vitro fertility commonly known as test tube baby in this technique ovum from female donor and sperm from male donor are collected to form zygote under laboratory condition. when zygote in early stage (up to 8 blastomere) could be transferred into fallopian tube is known as zygote intra fallopian tube ZIFT and more than 8 blastomere transfer into uterus is known as intrauterine transfer (IUT). In vitro fertilization is used to help with fertility or prevent genetic problems and assist with the conception of a child.
During this technique, mature eggs are collected from ovaries and fertilized by sperm in a lab. Then the fertilized egg is transferred to a uterus. So, the correct answer is (B) 'Uterus'.
In option (A) are not correct because Embryo are not transferred in the cervix because the main purpose of the cervix is to facilitate the passage of sperm into the uterine cavity. Maintains sterility of the upper female reproductive tract.
Option (C) are not correct because of Early embryos are transferred to the fallopian tube (8 blastomere). The main function of the uterine tube is to assist transfer of ovum from the ovary to the uterus.
Option (D) are not correct because the fimbriae of the uterine tube also known as the fimbriae tube are small finger-like projections at the end of the fallopian tube, through which eggs move from the ovary to the uterus. It is connected to the ovary.

Hence, the correct answer is option (B).

Additional information:
In vitro fertility is offered as a primary treatment for those women who are infertile over age 40. IVF can also be done if you have certain health problems like fallopian tube damage or blockage, ovulation disorder, Endometriosis, uterine fibroids etc.

Note: Your chances of having a healthy baby using IVF depend on many factors, such as your age and the cause of infertility. It is expensive and invasive. If more than one embryo is transferred to your uterus, IVF can result in a pregnancy with more than one foetus (multiple pregnancy).
