Generally, the prostate fluid secreted by men after sexual stimulation or before ejaculation may be interspersed with a little sperm. Prostate fluid is mainly secreted by the prostate gland and is an important part of semen. It is usually discharged through the urethra and can play a role in lubrication during sex and reduce vaginal friction. The prostate gland does not have the ability to produce sperm, so usually there is no sperm present in the prostate fluid alone. The prostate fluid that comes out of the glans area may be interspersed with a small amount of sperm during sexual intercourse because the patient is sexually stimulated, and this can be mixed to form semen and ejaculated during ejaculation. If the prostate fluid enters a woman’s vagina at this time and she is ovulating, there is a certain chance of pregnancy. When the doctor takes the prostate fluid for examination by massaging the prostate, the simple massage of the prostate is not sexually stimulated and usually does not contain sperm. The normal prostate fluid is generally translucent, thin and milky in appearance, if it turns out to be slightly yellow or yellow-purulent, it is suspected to be prostatitis and should be seen early in the urology department.
