The pill is an oral contraceptive that acts by preventing ovulation.
Condoms acts as a barrier and prevent sperms from reaching the cervix, thus preventing fertilization and pregnancy.
In vasectomy, the sperms cannot be transported into the female reproductive tract.
Copper – T acts as a mechanical contraceptive and renders sperms immotile by creating a hostile environment by releasing the copper ions.
