Briefly explain IVF and ET. What are the conditions in which these methods are advised?

Answers (1)

In-vitro fertilisation is also known as IVF, where sperm and ovum are taken out of the body of male and female (donor) and fertilised in laboratories, likely in a Petri dish. ET or embryo transfer is the next step performed after IVF. An embryo of up to 8 blastomeric stages is transferred to the fallopian tube. The embryo of more than 8 blastomeric stages is taken to the uterus. The babies born out of this method are often called test-tube babies as fertilisation, and some development of the zygote takes place in the laboratory.  This method is only used when medical treatment and psychotherapy fail, and couples fail in conception. These methods are also known as Assisted Reproductive Technology (ART). An extremely high degree of precision is required in this method with highly specialised doctors. Also, these techniques are very costly to install; hence they are only available at very few centres nationwide.
