Final answer:
A normal ejaculate contains between 50 to more than 300 million sperm, within an average semen volume of about 3.7 mL.
Step-by-step explanation:
A normal amount of ejaculate will yield anywhere from 50 to more than 300 million sperm. This range takes into account the average amount of semen per ejaculate, which is about 3.7 mL, containing 100-300 million spermatozoa. It's worth noting that semen is not just sperm; it's a mixture that includes sperm and fluids from accessory glands. As for vitality, only a fraction of these sperm are likely to become viable, mature sperm capable of fertilization.
