Please explain me for ivf?

Infertility tx: In-vitro fertilization (ivf), is a procedure that involves fertilization in a laboratory and implanting the fertilized egg (called a zygote) in the woman. This can be accomplished by utilizing the couples sperm and egg or with donor sperm and/or egg.

IVF: Ivf occurs after stimulating the ovaries with medications to increase the # of eggs produced. The eggs are removed when they are mature (size and lab tests done to confirm) and fertilized by placing the sperm into each egg or putting a number next to the egg inside the lab. The embryos generated can be transferred afterwards to create a pregnancy. Good quality embryos can be frozen for future.
