No, only one sperm can fertilizes one ovum. In women only one egg cell or ovum is produced per overy. And in men about thousands sperms are produced. But when only the strongest sperm reach near the ovum membrane then it hit the membrane and enter into the ovum then one enzyme is secreted and this seals the membrane to restrict other sperms. This system is called the 'lock and key system'.
