Question

In an assisted reproductive technology where gametes have been fertilized in vitro, which of the following is practicable for embryo transplantation in fallopian tube?
A) Only embryo upto blastomeres if zygote is not transplanted..
B) Only zygote is transplanted not embryo.
C) Either zygote or embryo with 8 blastomere phase transplantes.
D) Morula with an 8-24 celled stage is transplanted in a fallopian tube.

Answer 1

In vitro fertilisation is a process of fertilisation through which an egg is combined with sperm in the glass tube or outside the body.This process involves the proper monitoring and stimulating the ovulatory process and carefully removal of egg and then fertilize with sperm in liquid in vitro.

Complete answer:

IVF is a type of assisted reproductive technology mainly used for infertility treatment and gestational surrogacy.
Fertilization takes place in the glass tube then formation of zygote forms goes to embryo culture for 2–6 days.
After that it is transferred or implanted in the same or another woman's uterus for completion of further stages of pregnancy.
The zygote is transferred to the fallopian tube when it completes the 8 blastomere phase.This is done just to ensure the chances of successful implantation.

Hence the correct answer is option ‘C’ i.e, either zygote or embryo with 8 blastomere phases transplantes.

Additional information: There are some problems associated with IVF are multiple births, Spread of infection disease, Some birth defects (cleft lip, septal heart defects, Esophageal atresia and anorectal atresia), hypertension, impaired fasting glucose, impaired total body fat composition, and thyroid disorder.

Note: Louise Brown was the first child in July 1978 born by IVF successful treatment.This method is used in these cases: Fallopian tube damage, ovulation disorder, Endometriosis, Uterine fibroids, Impaired sperm production, fertility preservation of health issues and genetic disorder.
