Embodiment 1
[0027] Example 1: The glass slide flow method is used to determine whether the viscosity of the semen sample is normal or not—comparison with the dropper method
[0028] Materials and Methods:
[0029] 1. Obtaining Human Semen Samples
[0030] The semen samples used are provided by volunteers, so several healthy male volunteers are required to provide semen samples according to the following requirements:
[0031] 1) The sample is a sample of normal masturbation and ejaculation, which cannot be obtained from a condom
[0032] 2) The acquisition of samples must be strictly controlled within 3 to 7 days of the last ejaculation
[0033] 3) The semen sample is collected directly into the specially provided sample cup, fill in the ejaculation time and volunteer number, close the sample cup tightly, and send it to the laboratory or designated place within the specified time
[0034] 4) After one ejaculation, all samples must be collected into the sample cup without omission or a...

Abstract
The invention relates to a method for quickly and easily determining whether the semen viscosity of a male is normal or not. According to the method, a glass slide with a certain rough surface is adopted, a semen sample starts to naturally flow from a fixed position of the glass slide with a certain inclining angle under the action of gravity, an operator examines whether the front flowing end of semen exceeds a marking line or not within specified time, and the result can be used for determining whether the viscosity of the semen sample reaches the minimum standard of male fertility or not. Comparing research proves that the determination result of the method has no statistic difference with the result of standard methods, such as a pipette method and a glass rod method, recommended by WHO (World Health Organization), so that the method can be used for quickly examining whether the viscosity of a semen sample is normal or not and assisting in evaluation of male sperm motility. More importantly, an examinee can operate by self at a table by the method to complete the evaluation of semen viscosity, and reference is provided to further screening of infertility.
Description
technical field [0001] The invention relates to a quick and simple method for judging whether the viscosity of male semen is normal or not. Use a glass slide with a certain rough surface to make the semen sample flow naturally under the action of gravity from the fixed position concentration of the glass slide at a certain inclined angle, and check whether the front end of the semen flow exceeds the mark line within the specified time, and judge the semen based on the result Whether the viscosity of the sample meets the minimum standard for male fertility. The qualitative judgment results of this method are helpful to analyze the causes of male infertility. Background technique [0002] Male infertility is one of the most important problems in human reproduction, and it is the most common clinical problem and serious challenge in andrology. Due to the decline in the quality and quantity of male sperm in the past 30 to 50 years, the incidence of testicular cancer, poor test...
