Actually, during a female orgasm the cervix dilates and pounds against the wall of the vagina, which helps it to pick up semen and sperm. Fortunately or other wise, fertilization can occur without that action. It does make one wonder why men climax more easily than women, and why then our erections become too sensitive to continue intercourse until the woman reaches her climax.
If women required orgasms to become pregnant, then the only women who had babies would be the ones who had orgasms, thereby increasing the probability of passing along the "easy orgasm" gene.
If this were something that suddenly happened, like in the movie "Children of Men," then we might see a population dip for a few generations, but it wouldn't take long for things to start looking up.
But if orgasms were required for pregnancy (or even just made it slightly more likely), it would much more likely have been true from the earliest stages of human evolution, and thus we'd still have a huge population, all other factors being equal, because that natural selection would be happening all along.
From the article linked below: In those mammals that require the female to orgasm in order for eggs to be released, the clitoris is inside in the vagina. In those mammals the have an ovulation cycle, the clitoris has moved outside of the vagina. Some researchers speculate evolution did this to reduce conflicting signals to the female's reproductive system.
Other researchers speculate that the female orgasm is just an evolutionary byproduct of the male orgasm and serves no necessary purpose for the female. In other words: Female orgasms = Male nipples.
I find the first paragraph to be more convincing, but plenty of research still needs to be done for any firm conclusions.

That, or women would have to schedule a yoni massage (pussy massage) with a pro and have the other dude blow his load then.
