hi everyone my question is that my husband took ultrasound for testicular exam the results say venous diameter in valsalva and erect position is not increased . small 4mm hypoechoic area in mid right testicle could be cyst, otherwise both testicles are normal in size and echo-pateren, no hydereocele or other abnormality . impression; right sided varicocele right testicular cyst ?follow up is advised. so could he need surgery to improve sperm quality and increase more sperm .
