How do sperms reach the ovum to fertilize?
(Describe the Pathway)

Dear student 

Semen released by the male into the vagina of female has millions of sperm.
Motile sperms run very fast and pass through the cervix and uterus and reach a place called as junction of ampulla and isthmus in fallopian tube.

Above diagram shows the pathway of sperm to fallopian tube, depicted by arrow. 

Released ovum from ovary also reaches to this point. At isthmus-ampulla junction fertilization takes place by fusion of sperm with ovum.

So zygote is formed which matures into embryo.
