In vitro fertilisation is a technique that involves a transfer of which one of the following into the fallopian tube
Embryo only, upto 8 cell stage
Either zygote or early embryo upto 8 cell stage
Embryo of 32 cell stage
Zygote only
As we discussed in concept
In Vitro Fertilisation (IVF) -
Commonly known as test tube baby
- wherein
In this technique, ova from the wife/donor (female) and sperms from the husband/donor (male) are collected and are induced to form zygote under simulated conditions in the laboratory. The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT– zygote intra fallopian transfer) and embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development.
Option 1)
Embryo only, upto 8 cell stage
This option is correct.
Option 2)
Either zygote or early embryo upto 8 cell stage
This option is incorrect.
Option 3)
Embryo of 32 cell stage
This option is incorrect.
Option 4)
Zygote only
This option is incorrect.
