How does a sperm meet an ovum?
When the father’s vagina is put into the mother’s vaginal cavity and ejaculated, hundreds of millions of sperm are released from the vagina into the vaginal cavity.
Hundreds of millions of sperm pass through the vaginal cavity, cervix, and uterine cavity to reach the fallopian tubes.
There they swim further and race to the end of the fallopian tube, the fallopian tube. One sperm out of hundreds of millions of sperm comes out of the mother’s ovary and meets one waiting for egg (egg) in the fallopian tube.
