Hey all! Today's lesson is about In-Vitro Fertilization, or IVF.
What is IVF? IVF is the process of manually combining the egg and sperm in a laboratory dish, and then placing the embryo back in the uterus. Sometimes the embryo is placed in the fallopian tube instead of the uterus. Usually, when the doctors extract the eggs, they extract more than one, so that if the first egg does not get fertilized, they will have extra eggs to complete the process. If any eggs that have been extracted are not used, they are preserved in liquid nitrogen, enabling them to be used again.
Before the embryo can be placed in the uterus or fallopian tube, there is a test done, called Pre-implantation Genetic Diagnosis, or PIGD. PIGD is a test used to confirm that there are no genetic or chromosomal disorders in place during IVF. This can also be called Embryo Screening.
That's all for now! Hope it helped...
