In the laboratory inspection of men's infertility, of course, the sperm examination is of course the sperm examination.Conventional semen inspection indicators include: semen, color, pH, condensate, liquefaction, sperm count, sperm vitality, etc.
Among them, sperm vitality is a very important indicator, but in the past, it made subjective judgments based on the results of the inspectors under the results of the naked eye under the microscope. It was not only affected by the technical level of the inspector, but also with considerable subjectivity.Some laboratories conduct classified records according to the good or bad of sperm movement according to the methods prescribed by the World Health Organization.Therefore, semen examination has been at a lower level.
In the 1970s and 1980s, foreign countries successively developed the automatic analysis system of laser light scattering measurement technology and computer image processing, so that the level of semen examination reached a very precise and perfect level.It is gratifying that after years of hard work, my country has designed and developed the above two systems by itself, filling the domestic gap and reaching my country's sperm function analysis technology to the international level.Ma Xiaonian, the Institute of Science and Technology of the National Family Planning Commission, used the two sets of instruments and equipment jointly developed with Tsinghua University to test the semen testing of thousands of normal people and infertility patients.Semen of different species of animals such as cattle and other types of animals was tested to obtain a large amount of first -hand information.
According to the test, the distribution of the sperm movement speed of normal human sperm is 36 microns/second, and its average exercise speed is 35 microns/second.There is a significant difference between /second and the two groups.
