First, the human reproductive system has a remarkable ability to produce a vast number of gametes; for example, men can produce millions of sperm daily throughout much of their lives. Second, women are born with all the eggs they will ever have, typically around 1-2 million, but this number decreases significantly by puberty and continues to decline with age. Lastly, the average lifespan of sperm inside a woman's body can range from 3 to 5 days, but they can survive up to a week in optimal conditions, making timing crucial for conception.
