If the sperm is thin and watery, it may affect fertility. If it is discharged within 30 minutes of the wildflower into the sperm thin like water, usually does not affect fertility. If you are not having frequent sex, the spermatozoa is thin and watery and the amount is relatively small. The absence or underdevelopment of the vas deferens and seminal vesicle glands may affect sperm viability, sperm quality, and sperm quantity, which may affect fertility. When sperm is first expelled from the body, it is somewhat sticky. But usually within 30 minutes, it has to liquefy into a watery consistency before the sperm can escape from the semen and go directly to the uterus. So a watery semen coming out of the vagina is normal and will not affect fertility. Patients who have just discharged semen thin as water should go to the urology department of the regular hospital in time.
