Yes, even a tiny amount of sperm can cause pregnancy. It only takes one single, healthy, motile sperm to fertilize an egg. While a large volume of semen contains millions of sperm, a significant percentage are not viable. However, even a small amount of semen, or even pre-ejaculate (pre-cum), can contain enough viable sperm to result in conception.

Understanding the Risks
It's crucial to understand that the presence of even a small number of viable sperm in the vagina increases the risk of pregnancy. This highlights the importance of responsible sexual practices and reliable contraception if pregnancy is not desired.
