Oligospermia and hypospermia are common causes of male infertility. Many patients have these two reasons. Most of the patients tend to pursue what has a fantastic effect of drugs, the pursuit of what special drugs, ancestral secret recipes, the results ignore the most important point, the result is brought about by the sperm quantity quality suddenly high and low, or even decline. The best time for treatment is delayed. What is the most important point? That is to ignore the search for the cause of the disease! It is far better to look for the cause of the disease than to rush to treat it right away. This is like planning to go to Beijing, but the direction is chosen to go to Hanoi, Vietnam, which will only be more and more different from the expectations, and it is impossible to achieve good results. Some common causes of disease are easily detected in a standardized large hospital. When a patient comes to a male specialist in a large hospital like ours, we usually do a careful physical examination to see if the patient’s development is normal, what is the size of the testicles and epididymis, whether there are varicocele, whether the vas deferens is developing normally, and so on. Then a series of tests will also be done for the patient with the aim of ruling out common causes, such as blood tests for sex hormone six to see what the hormone levels are; ultrasound tests to rule out inflammation of the testicles and epididymis, tumors, and varicose veins in the spermatic cord; routine prostate fluid tests to rule out prostatitis; and mycoplasma chlamydia tests to rule out these microbial infections. Once the problem is found, immediately carry out targeted Chinese and Western medical treatment to remove the cause. Then use a combination of Chinese and Western medicine and other drugs to promote testicular epididymal function. This treatment often has a half-hearted effect and saves time and money. This is the way to treat infertility with little or weak sperm.
