Sperm that look like water usually suggests a lower number of sperm in the semen, a lower density of sperm, and a lower viability of sperm, commonly seen in azoospermic patients. It is usually associated with sperm quality. Sperm like water is usually due to a dysfunction of the spermatogenic epithelium of the testes, resulting in a reduced sperm count, which leads to the symptom of watery semen. It can also occur due to pituitary insufficiency or adrenal hypofunction, where low testosterone levels occur, affecting the function of the spermatogenic epithelium of the testes. In patients with varicocele, it can also lead to dysfunction of the spermatogenic epithelium of the testes. When the symptom of sperm like water appears, you should go to the hospital in time for consultation and active treatment to avoid further progress of the disease.
