What happens to the sperms which fail to meet the ovum?

Jasmine, these information below will answer your question, dear...

"As sperm swim through the vaginal canal and into the cervix, they hit a "fork in the road," so to speak. At this juncture, some sperm travel to one fallopian tube, while the rest move on to the other. However, only one fallopian tube has a fertile egg at a given time. The sperm that do not reach an "impasse" surround the mature egg and compete with the other sperm in trying to penetrate it. If a woman's sexual and reproductive health are in good working condition, the first sperm to cross the finish line (enter the egg) succeeds in fertilizing it. "Helper" sperm can also be credited for easing fertilization by allowing this particular sperm access to and contact with the mature egg during its trip. With conception initiated, the now fertilized egg sets off some mechanisms, such as thickening of cervical mucus and hardening of its outer surface (zona pellucida), to block all other sperm from entering the egg."

"The sperm do eventually die and they are just expelled through normal secretions."
