The more common test is semen analysis, which is an important indicator of semen quality and can also reflect male fertility. If a man has weak sperm, oligospermia, dead sperm or azoospermia, it may affect his fertility; if he does not have these problems, it will have little effect on his fertility. A semen analysis test costs about$60 and takes about 1-2 hours, as it takes an hour to determine the liquefaction time of semen.
