How should varicocele be examined?

Patient's question:

I got married to my wife, but we haven't been able to have children. Recently, my wife and I went to the hospital for a check-up. It turns out that she's fine, but they said I have varicocele, which affects the quality of my sperm, making it difficult to conceive. I'm really frustrated. Could you please tell me how to best check for varicocele?

Doctor's answer:

How to perform a thorough examination of varicocele in men
In the early stages of varicocele, it may be completely asymptomatic or manifest as scrotal swelling, a heavy and dragging sensation, relief during standing, walking, or exertion, and a reduction in the degree of dragging and swelling after lying down and resting. This does not necessarily correlate with the severity of the varicocele. Sometimes, it may also be accompanied by symptoms of neurasthenia, specifically as follows:
1. Swelling, dragging sensation, and in the scrotum or testicles;
2. Recurrence of infertility;
3. Symptoms of neurasthenia;
4. Sexual dysfunction.
There are many methods for treating infertility and subfertility. The best approach is to achieve pregnancy scientifically and quickly. It is recommended that you seek timely treatment at a formal infertility and subfertility specialty hospital for a proper understanding and diagnosis.
