Patient's question:
Here is the English translation of your text, with line breaks preserved as instructed:"In April, I had microscopic surgery for left varicocele. The follow-up examination said the surgery was very successful, with no reflux. However, when checking the sperm quality, the vitality is still not enough, with a survival rate of 72%. Now I feel there is no curvature, and no varicose spermatic veins are detected when inhaling. But there is a thick, bent tube next to it—is it an epididymis or something? On the right side, there is one too, but it’s thicker on the left. I’d like to ask why."
Let me know if you'd like any refinements!
Doctor's answer:
Varicocele refers to the tortuous, elongated, and dilated veins within the spermatic cord, leading to impaired venous drainage, which lowers the temperature of the scrotum. This may potentially interfere with sperm quality and even affect the patient's fertility, resulting in infertility. After this surgery, it can be beneficial for semen quality. Therefore, if a patient again exhibits clinical symptoms of varicocele, it is recommended to promptly visit a hospital for relevant examinations to confirm the diagnosis. Specific tests such as scrotal and spermatic cord vascular color Doppler ultrasound and a detailed semen analysis can be performed. If varicocele is present along with abnormal semen analysis results,
