Absolutely. In all couples not getting pregnant after a year or more trying, the male partner should get a Semen Analysis; 40-50% of these men have a sperm issue, ranging from mild to severe sperm problems. About half the time the sperm issue is the only problem, and the other half have male and female factors together, like blocked tubes or low egg supply. If your sperm test is normal you don’t need much else in the way of testing. Men with abnormal sperm counts may need hormonal or genetic blood work.
