Definition: In-vitro fertilization

Explanation: In-vitro fertilization literally means "fertilization in glass". The fluid obtained from the follicles is carefully examined in the IVF laboratory and the eggs contained therein are isolated and placed in culture media inside an incubator. A few hours later, several thousand processed sperm are placed around each egg. In some cases where sperm counts are very low, the process of fertilization must be assisted via the injection of individual sperm into each egg
