Normally, sperm entering the vagina liquefy under the action of the fibrinolytic enzyme system. Only a small percentage of sperm can enter the uterus and fallopian tubes to complete fertilization.
After entering the vagina, some of the semen will naturally flow out of the body with the force of gravity. The sperm in the semen that remain in the vagina are liquefied by the action of the fibrinolytic enzyme system. Most will die on their way to the female fallopian tube. Very few sperm actually reach the juxtaposition of the female fallopian tubes for fertilization. Only a small percentage of sperm can enter the uterus and fallopian tubes and reach the juxtaposition to complete fertilization.
The success rate of sperm-egg binding is higher when intercourse is performed around the time of a woman’s ovulation. The sperm combines with the egg cell to form a fertilized egg that travels through the fallopian tube to form a blastocyst. It then travels to the inside of the uterus to form the mulberry embryo. The embryo is deposited in the lining of the uterus and gradually develops into an embryo. Throughout the gestation period, it develops into a fetus, which is finally born into a new life by a woman.
