Cold compresses are recommended for mild varicocele. Varicocele can be diagnosed by ultrasound and other methods. Mild degrees can be treated with medication or cold compresses, while physical therapy is less effective in severe patients and can be used as an adjunct to other treatments. Varicocele is a microvascular lesion that causes pain and is one of the main causes of male infertility. It is prevalent on the left side and the main screening modalities include color Doppler ultrasound, CT, MRI, palpation and other methods. Varicocele mainly affects the testicles. The onset of varicocele slows down the blood flow in the blood vessels in the testicles, which leads to an increase in temperature. The high temperature is not conducive to the synthesis of spermatozoa, and it can lead to spermatogenic disorders. If the degree of varicocele is mild, without the need for surgical treatment, you can follow the doctor’s instructions to use the scrotal cold compress patch, which is conducive to the return of blood to the testicles, minimizing the impact of varicocele on the spermatogenic function of the testicles. In the process of cold compresses, we should pay attention to whether the discomfort of the testicles has been reduced or aggravated, and pay attention to timely follow-up.
