Question
A couple where both husband and wife are producing functional gametes, but the wife is still unable to conceive, is seeking medical aid. Describe any one method that you can suggest to this couple to become happy parents
Solution
In vitro fertilisation: In this method, fertilisation occurs outside the body and is followed by embryo transfer (ET). This technique is applied when the fallopian tube of the mother is blocked and she is unable to conceive. In this technique, the egg of a wife/donor is removed and fertilised (in vitro) by the husband/donor sperm outside her body under sterile conditions. The fertilised egg which reaches the 8-celled stage is transferred into the fallopian tube and the embryos with more than 8 blastomeres into the uterus to complete their further development.
