It only takes one sperm to fertilize an egg and lead to pregnancy. The number of drops of sperm needed to achieve this can vary depending on the size of the droplets and the concentration of sperm in the semen.
On average, a man can release between 1.5 to 5 milliliters of semen during ejaculation. A milliliter of semen contains millions of sperm. The concentration of sperm in semen can vary widely, but a healthy sperm count is generally considered to be 15 million or more sperm per milliliter of semen.
So, even a small droplet of semen can contain enough sperm to fertilize an egg and lead to pregnancy. It’s important to remember that pregnancy can occur if semen comes into contact with the vagina or vulva during sexual intercourse or other sexual activities, regardless of the amount of semen or the number of drops. It is always important to use contraception if you are not planning to conceive.
