Do you know about male infertility? Male infertility accounts for 50% of all infertility cases, and is a problem for many families. How to diagnose male infertility? Semen analysis is the simplest and most direct test method. According to the test results, it is mainly divided into azoospermia, oligospermia, weak spermatozoa, and semen indigestion. The types are different and so are the treatment options, but one of the most difficult to treat is azoospermia, that is, the absence of sperm in the semen. Such patients could be said to have lost their fertility in the past, but now with the improvement of surgical techniques, it is no longer a dream for azoospermia patients to have pro-life children. Professor Yuan Mingzhen of the Second Hospital of Shandong University introduced that minimally invasive surgery such as vasovaginal epididymal anastomosis and spermoscopy treatment can treat obstructive azoospermia caused by hematospermia, seminal vesiculitis, seminal vesicle stones and epididymitis; while microscopic spermatic varicose veins stage, comprehensive therapy and microscopic sperm extraction can solve the fertility problem of more than 50% of non-obstructive azoospermia patients. Therefore, male infertility is no longer a medical problem.
