उत्तर
-
It is also known as in-vitro fertilization.
-
In this process, sperm is collected from the father or any male donor and similarly, an ovum is collected from the mother or any female donor, then this is fertilized in the laboratory using sterilizing conditions.
-
Now when the embryo is formed, it is transferred to the mother or the surrogate.
-
Embryo up to 8 blastomere stage is transferred in the fallopian tube whereas blastomere more than 8 blastomeres is transferred in the uterus.
-
The process is carried out in a laboratory along with high precision and a sterilized environment and these methods are a part of Assisted Reproductive Technology(ART).
-
Though these processes are difficult and high precision should be maintained they have many helped many couples who were unable to conceive.
