Four indicators to pay attention to
Semen volume: The normal volume should be greater than or equal to 2ml (milliliter). If it is more than 7ml, it is excessive. At this time, not only the sperm density becomes low, but also it is easy to flow out of the female vagina, resulting in a decrease in the total sperm count, which is common in patients with seminal vesiculitis. If the total amount is less than 2ml, it indicates a low semen volume, and if the total amount is less than 1ml, it indicates a low semen volume, which can easily lead to infertility.
Color: The normal color is grayish white or slightly yellow. If the semen appears milky white or yellowish green, it indicates inflammation of the male reproductive tract or accessory gonads. "If there is pink or red color, or if red blood cells can be seen under a microscope, it is bloody semen, which is commonly seen in patients with accessory gonads and post urethritis, and occasionally in patients with tuberculosis or tumors.".
Liquefaction time: After normal semen is ejaculated, it will become gelatinous under the action of seminal vesicle coagulase, and after 15-30 minutes, it will become liquid under the action of prostate liquefaction enzyme, known as semen liquefaction. If semen does not liquefy 30 minutes after ejaculation, it is considered abnormal.
Viscosity: Touch liquefied semen with a glass rod and gently lift it to form semen filaments. If the semen is normal, the length of the semen filament should be less than 2 centimeters.
In addition, indicators such as semen pH and sperm motility need to be tested to obtain accurate results. If a man finds that none of the above four indicators are normal, he should go to the hospital for further laboratory tests.
Three tests should be performed for abnormal semen
Examination based on medical history: The presence of cryptorchidism and varicocele can be preliminarily determined through medical history. By inquiring about medical history, physical examination, and other laboratory auxiliary tests, the cause of oligospermia can be found in most cases. Secondary oligospermia can be diagnosed when oligospermia is analyzed in semen and accompanied by the etiology of the disease that causes oligospermia.
Through abstinence test: Men can abstain for 3 to 7D, and those with semen routine analysis more than 3 times and sperm density less than 20 million without finding any cause can be considered as idiopathic oligozoospermia. When sperm density ≤ L × At 10/ML, severe oligozoospermia can be diagnosed.
Immunological examination: Immunological examination can determine whether there is autoimmune disease, and chromosome karyotype analysis can determine whether there is chromosome abnormality. Determination of serum FSH, LH, T, and PRL is also an important method for oligospermia testing. If FSH, LH are lower than normal, it is secondary oligospermia, and elevated PRL is oligospermia caused by hyperprolactinemia.
