How to read a semen report, why talk about this topic? Because in the clinic, patients have many questions about semen reports, often asking, “Does this item have an effect? Can I get pregnant, how long does it take to get pregnant, is it normal, what if it is not normal? I would like to answer this question together with my male friends with abnormal semen. First, what to look for, which items of semen to look for, and second, how to look and how to look at these results. First, what do we look for when looking at semen. Nowadays, semen report forms often have dozens of parameters, 40, 50, or even more parameters, like our hospital labs, and the analysis report forms are 4. Generally speaking, although there are dozens of parameters, the most we look at clinically is not more than 10 items. The first thing to look at is the amount of semen. The normal amount of semen is 2 to 6 ml, if it is less than 2 ml, it means that the amount of semen is a bit low, although the number of sperm per ml is a lot, but half a ml is too little overall. Too little will affect, too much will also be a problem, too much semen will be diluted, but also affect his fertility. The second thing to look at is the appearance of the semen ejaculation color. Under normal circumstances, men who have regular semen emission, semen should be milky white, if long time without semen emission, should be some light yellow. If the semen is red in color, it is hematosperm, there is blood in it. If the semen is very yellow, it is not a long time to discharge semen, there may be inflammation and infection in the semen, there is pus in it, if the semen is very yellow and thick, there are pus cells in it, there will be yellow semen. The common is these two, generally speaking is milky white, this is the case of semen, the third to look at the pH value pH value of the normal case is 7.2 to 8.0, weak alkaline, most of the semen between 7.4 to 8.0, if the pH value is acidic, such as 7.0 below, often suggests the seminal vesicle gland and prostate gland problems, but if too high, also often suggests If it is too high, it also often indicates inflammation. This means that the pH value should be within a reasonable range, and neither too acidic nor too alkaline is good. Fourth, the liquefaction of semen is a very important parameter. Why does it liquefy? The seminal vesicle fluid contains substances that promote the coagulation of semen. The process of coagulation is to protect the sperm, other debris cannot enter and the sperm cannot run out. Prostate fluid contains substances that promote liquefaction, hydrolytic protease, which can promote semen liquefaction. 15 to 20 minutes should liquefy, if it is not liquefied in more than half an hour, it may be a little delayed, and if it is not liquefied in more than an hour, it is not liquefied. The liquefaction is a very important indicator. The fifth to look at the density of sperm is the number of sperm per unit volume, we now call the concentration. 40 years ago, the density of sperm required 60 million per milliliter, 20 years ago 20 million is enough, a year ago 15 million is enough, this degradation is mainly related to the environment, lifestyle. Now are sitting there, do not go to work in the field, less labor, the original lifestyle changes. Sixth, the viability of the past requires more than 60%, the earliest requirement of more than 70%, a year ago, the World Health Organization set a standard, more than 40% can be, the standard is getting lower and lower. The other is vitality, the ability of sperm activity, including fast linear motion, that is, the A class, and slow linear motion, that is, the B class. In the past, fast linear motion was required, with A-class sperm greater than 25% and A+B greater than 35%, which was the standard a few years ago; a year ago, A+B greater than 32% was sufficient, which is the ability to move. Seventh, we need to look at the morphology of the sperm The normal morphology requires more than 30%, and later requires more than 15%, a year ago the World Health Organization stipulated that a normal morphology of more than 4% is sufficient, this standard is getting lower and lower. At present, there are several types of semen tests, some use computer analysis of semen, some are manual, microscopic, there are at least five types of test methods, the results are not uniform, in the case of computer analysis, some hospitals use the fifth edition, that is, the latest standard, some hospitals still use the fourth edition, that is, the original standard, so the whole situation of semen is rather confusing.
