A human egg contains? Which choice is true about both sperm and ova production?

The human egg does contain both sperm and ova production because the sperm swims in and enters the ova which makes the ova hard so no other sperm do not swim in side. then it multiples 2 4 6 8 and so on until i it reaches the uterus and then is stored in there until the baby is due....... then you enjoy your bundle of joy!!!!!!!!!!!!!!
