You can't see sperm with the naked eye. They're incredibly tiny, about 50 times smaller than the width of a human hair! You'll need a microscope to see them.
If you're concerned about the health of your sperm, the best way to check is to get a semen analysis from a fertility clinic or lab. These tests can tell you a lot about your sperm count, shape, and motility (how well they move).
You can also find at-home semen analysis kits that can tell you if sperm are present in your semen. Some of these kits can also assess sperm motility.
If you have any concerns about your fertility, it's important to talk to a doctor.
