Whether thick or thin sperm is better cannot be generalized and needs to be analyzed on a case-by-case basis. If there is an abnormality in the sperm, it is recommended to consult a urologist in a timely manner and make a judgment after a comprehensive assessment of the doctor’s condition. Normally, after ejaculation, the spermatozoa appear jelly-like and liquefy into a thin liquid spermatozoa within 20 minutes. Therefore, as long as the sperm is jelly-like within 20 minutes, that is, thick in nature, it is a better state; if the sperm is still jelly-like after 20 minutes, it is an abnormal situation, which may be caused by prostatitis and other diseases, and need to pay attention to and timely treatment. If the thinning of sperm occurs after 20 minutes, this is normal. However, if the thinning of sperm occurs immediately after ejaculation, then it is an abnormal situation; we need to consult the urology department in a timely manner, complete the relevant examinations under the guidance of the doctor, and carry out treatment after clarifying the cause of the disease.
