Yes, but they're not alive in the sense that a developing fetus is. They might be living organisms, but to what extent could we consider them alive? As I already said, we wouldn't consider viruses to be alive, but they show more properties of a living organism than sperm cells do. Comparing sperm cells to a fertilized egg is still ridiculous. Sperm cells only carry the potential for a human life. It's merely a functioning cell which acts on reflex. A developing fetus actually has the ability to grow; it's still a leap to compare it to sperm cells.
