An average human ejaculate contains about 180 million sperm (66 million/ml), but some ejaculates contain as many as 400 million sperm. Both quantity and quality of the sperm are important determinants of fertility. A man is considered clinically infertile if his sperm concentration falls below 20 million/ml semen.
The reality is that regular ejaculation certainly isn't universal. Some women do it once in a lifetime, but never again. The actual percentage of females who ejaculate is uncertain. However, in Masters and Johnson's famous lab experiments with over 400 women, they did not record anyone who ejaculated at climax.
