How to judge the quality of semen

The quality of semen can be evaluated through routine examination of semen, mainly observing semen volume, liquefaction time, sperm concentration, motility, morphology and other indicators. Semen quality is affected by many factors such as living habits, environmental factors, diseases, etc. If the test results are abnormal, the cause needs to be further investigated based on clinical symptoms.

Normal semen is gray-white or light yellow, and the liquefaction time is usually within 15-30 minutes. Semen volume less than 1.5 ml may indicate seminal vesicle or prostate problems, while more than 6 ml may dilute sperm concentration. The sperm concentration should reach more than 15 million per milliliter, the proportion of forward moving sperm should be no less than 32%, and the proportion of normal morphological sperm should exceed 4%. Factors such as long-term smoking and alcohol abuse, high temperature environment, reproductive system infection, etc. can lead to decreased sperm motility or increased malformation rate.

The appearance of blood streaks in semen may be caused by inflammation such as seminal vesiculitis and prostatitis. If accompanied by ejaculation pain, you need to be alert to genitourinary system diseases. The complete lack of liquefaction of semen may be related to insufficient fibrinolytic enzyme secreted by the prostate, which is common in patients with chronic prostatitis. Some patients with oligozoospermia have varicocele, and the feeling of scrotal swelling worsens after standing for a long time. The diagnosis can be confirmed through scrotal ultrasound.

Men preparing for pregnancy should conduct a semen test 3 months in advance and avoid ejaculation within 2-7 days before the test to ensure the accuracy of the results. You need to keep your scrotum ventilated every day, and avoid soaking in hot springs or wearing tight pants for long periods of time. Appropriate supplementation of zinc, selenium and other trace elements can help improve sperm quality, but patients with severe oligoasthenozoospermia need to be treated with L-carnitine oral solution, spermatogenic tablets and other drugs under the guidance of a doctor.
