| The process of fertilization |
|
| The egg is covered by a jelly-like shell - Zona Pellucida and layers of cells called Corona Radiata. |
|
| When sperms meet the egg, many try to penetrate the outer shell but only one succeeds. |
|
|
A chemical reaction prevents other sperms from penetrating the Zona Pellucida. |
|
| Once the egg is fertilized, it travels to the uterus from the fallopian tube and gets implanted into the uterus. |
|
| The life span of an egg, once it is released, is a maximum of 48 hours and for the sperm, it is 72 hours. |
|
|
If fertilization does not occur, the inner lining of the uterus is shed as menstrual bleeding. |
