Question

why such a huge number of sperms are ejaculated deposited along with semen in female reproductive tract??​

Answer 1

$\sf\large \green{\underbrace{\red{Answer⋆}}}:$

At coitus, human sperm are deposited into the anterior vagina, where, to avoid vaginal acid and immune responses, they quickly contact cervical mucus and enter the cervix. Cervical mucus filters out sperm with poor morphology and motility and as such only a minority of ejaculated sperm actually enter the cervix.
