As the name suggests, varicocele refers to the thickening and tortuous blood vessels of the spermatic cord in the scrotum due to poor blood return or even backflow, forming a worm-like mass in the scrotum and sometimes accompanied by cramping and discomfort, generally more on the left side than on the right. Varicocele can be classified as mild, moderate or severe according to the degree of the disease, and its harm is mainly caused by the symptoms of pain and discomfort and infertility. Therefore, treatment is only necessary if it causes clinical pain and discomfort or if it affects the quality of semen. So how can it be treated? Because conservative treatments such as medications are generally ineffective, the main treatment at present is surgery, which includes open surgery, laparoscopic surgery and microscopic surgery. The microscopic surgery is the most ideal surgery for varicocele treatment in the world. Prof. Yuan Mingzhen of Shanda Second Hospital introduced that because this surgery is operated with a microscopic magnification of more than 15 times, not only can all the veins be finely ligated, but also the lymphatic vessels and arteries can be preserved, which protects the testicles to the maximum. If you find discomfort in the scrotum or poor semen quality, and if there are tortuous masses in the scrotum when you touch them with your hands or observe them with the naked eye, then you basically have varicocele, and it is time to go to the hospital.
