Were heading to fallopian tubes boys, just got through the vagina. Most of our ships didn make it
Oh no! A white blood cell directly ahead, Divert course
We only have a small fleet remaining of about 3000 seamen
Approximately 250 million sperm enter, most of them are killed by acid from the vagina that protect against pathogens
The remaining sperm must navigate through the Cervix, many take the wrong path and die.
We must find the egg brothers
Approximately 3000 sperm remain while they are attacked by leukocytes while navigating towards the Fallopian Tubes
Fertilization and Implantation
Doorway to the Fallopian Tube, Sperm are provided with nourishment.
there is the doorway to the Fallopian tube!
About 10-30 Sperm remain. They are provided with nourishment from the Fallopian Tubes.
The remaining sperm must attempt to find the egg. Once one sperm enters the egg, 23 individual chromosomes of sperm and egg pair up. Once fertilizeed the egg will head back into the wall of the Uterus.
