Gametes (Sex Cells) have adaptions to increase the chances of fertilization and successful development of an embryo. Sperm cells are produced in large numbers to increase the chance of fertilization. They have:
-A tail to move them towards the egg cell
-Many mitochondria to provide energy to make the approximate 12cm journey to the egg
-An acrosome (tip of the head) that releases enzymes to digest and penetrate the egg membrane
The acrosome is a structure located at the tip of the sperm's head, containing enzymes that help the sperm penetrate the outer layer of the egg. Without the acrosome, the sperm lacks the necessary tools to fertilize the egg successfully. It is like attempting to open a door without a key.

No you cant cant fertilize the ovum without sperm. However there is a method that is popularly used to avoid pregnancy, and that is to withdraw the penis when the feeling of orgasm comes on. The man quicly withraws his penis and finishes his orgasm by continuing to masturbate outside the vagina. This method is unreliable because a man can without realizing it release some sperm even before he orgasms.
