The fact that sperm is milky and a little sticky does not mean that it is abnormal. Under normal circumstances, the sperm is slightly yellowish and milky white. The stickiness may be related to the long period of time without sperm discharge, or it may be related to not drinking enough water in general. It is recommended that if you are worried about abnormal sperm, you should have a semen test. The semen test requires 5-7 days of abstinence before taking semen for testing to observe whether the concentration of sperm is normal, whether the pH value of semen is greater than 7.2, whether the vitality of sperm is normal, and whether the liquefaction time of semen is within 60 minutes. If these indicators are normal, there is usually no major problem. It is recommended that you should usually drink more water and have regular semen discharge so that the sperm will not be too sticky.
