Research has found that a man can release approximately 200 million sperm with each ejaculation. To assess a man's fertility, one should undergo a semen analysis at the hospital, examining the quantity, texture, and color of the sperm to detect any abnormalities.
What are the normal indicators for male sperm?
1、Semen Volume
Normally, the semen volume per ejaculation should be between 2 to 7 milliliters. A volume exceeding 7 milliliters indicates excessive semen with a low sperm density, which may lead to leakage from the vagina and reduce the total sperm count. A volume less than 2 milliliters indicates insufficient semen, likely reducing the sperm count and potentially causing male infertility.
2、Color
A yellowish-green or milky white color in the semen may indicate infections in the reproductive tract or gonads. A red or pink hue, or the presence of red blood cells under a microscope, is referred to as hematospermia, suggesting inflammation in the posterior urethra or accessory glands, possibly due to malignant tumors or tuberculosis.
3、Liquefaction and Semen Thread Length
Normally, semen coagulates into a gelatinous form after ejaculation due to the action of coagulase from the seminal vesicles. It then liquefies within 30 minutes under the influence of prostate enzymes. Failure to liquefy after this period is abnormal. When testing, a glass rod is used to lift a thread of liquefied semen; a normal thread length should be less than 2 centimeters.
4、Sperm Viability Approximately 50%
When checked within one hour of ejaculation, the motility of sperm should exceed 50%. Low sperm motility and viability may indicate conditions like varicocele or inflammation of the accessory glands.
5、Sperm Count
Normally, there should be more than 20×10^6 sperm per milliliter of semen. A lower count might be due to disorders in sperm production or reduced chances of sperm reaching the fallopian tubes and uterine cavity, decreasing fertility.
6、pH Level
The normal pH of semen should be between 7.2 and 7.8. A pH lower than 7.2 could suggest urine contamination or ejaculatory duct obstruction, while a pH higher than 7.8 might indicate seminal vesiculitis.
Reminder:
Adopt a healthy lifestyle and consume zinc-rich foods such as eggs, seafood, and meat. Avoid obesity by maintaining an appropriate weight, quit smoking and drinking, engage in regular physical exercise to enhance physical fitness, reduce psychological stress, and consume vitamin C-rich vegetables and fruits as vitamin C can protect semen from free radical damage and improve sperm quality. Moderate sun exposure promotes vitamin D3 synthesis, enhancing sperm penetration. Limit the frequency of sexual activities, maintain local hygiene, and avoid prolonged exposure to high temperatures.
