Is there a home fertility test for men?

Yes. Not a full test: The over-the-counter fertility test for men is called spermcheck and tests if a man's sperm count (concentration) is low or normal. A full semen analysis (sa) through a fertility clinic looks at sperm count as well as motility (% that are moving) and morphology (% of normal-shaped sperm). Some clinics test sperm antibodies too. So the home test is better than nothing but not as good as a full sa.
