The theory behind the biological purpose of the female orgasm is that it causes the uterus to expand and contract in quick succession. This creates a vacuum and helps to 'suck' the sperm cells up into the uterus where they have a better chance of coming in contact with an ova and conceiving a fetus.
So actually there's a bit of a better chance, but plenty of women get pregnant without having an orgasm.
This used to be called (really) the "Up Suck Theory." The Victorians used it. It was probably used as a way for women to actually feel OK about orgasms.
However, it's been disproven in humans. The human cervix and uterus does
not suck sperm in when orgasm occurs. It does occur with some animal, pigs I know for sure and there are others. Also a female pig's clitoris is on the
inside of her vagina. Lucky girl, I guess. Pigs still have oral sex...
But, orgasm may cause women to want to have sex more often, but we have no "Up suck" when we come.
