Sperm quality indexes

This is an automatically translated article.

1. How important is sperm quality?

Sperm quality affects fertilization (eggs in females and sperm in males). A qualified sperm count will help increase sperm quality, thereby increasing the chances of pregnancy.
In addition to reproductive health problems, if a man has low sperm quality, it is often a warning factor for a number of diseases such as:
Obesity High blood pressure Risk of diabetes Heart disease, stroke stroke High frequency of metabolic syndrome

2. Evaluation of sperm quality by semen analysis

Semen analysis is a test of freshly ejaculated semen. After taking the sample, the semen analysis should be done within 1.5 hours. In order for the test process to give the most accurate results, men should note a few things before taking a semen sample as follows:
It is recommended to limit ejaculation for 2 to 7 days before preparing for a semen analysis in order to ensure the quantity and quality of semen. Do not use stimulants, alcoholic beverages such as beer, wine, ... and do not use drugs containing hormones. If you are using antibiotics or dietary supplements, you should inform your doctor. Eat nutritious food, exercise your body, get enough sleep, keep your mind comfortable. Drink plenty of water, add foods rich in zinc, selenium, and minerals. Before taking a test sample, you should wash your hands with clean water, do not use soap, because it can kill sperm. It is advisable to take a semen sample in the morning and absolutely do not conduct the test when the body has a high fever or is in an inflammatory or infectious state.

3. Indicators of sperm quality

To know if the quality of sperm is really good, the following indicators are often used to evaluate. Specifically:
Lylysis: Normally, semen after ejaculation will liquefy itself at a temperature of 37 degrees Celsius, the lysis time is 15-60 minutes. Long lysis time may be due to prostatitis. Color: Semen after lysis is homogeneous, white or opaque gray. If the semen analysis shows that the semen is yellow, it could be due to the use of certain vitamins, urine or infection. Pink or red semen may be caused by blood. Clear white color may be due to low sperm count. If the pig is flat, it may be due to a urinary tract infection.

Volume: Calculated in ml, accurately estimated by calculating the weight of the semen sample. Normal semen volume is ≥ 1.5ml. Low semen volume may be due to tubal occlusion, aplasia of the seminal vesicles, or retrograde ejaculation. Viscosity: This method is assessed by observing the elongation of the pipette droplet. The index is normal when the droplet is sporadic or does not extend more than 2cm. If the consistency is high, it is usually due to abnormal components in the semen. Evaluation of sperm survival: Sperm staining by eosin-nigrosin method to determine the percentage of live sperm. If dead spermatozoa will be pink due to dye staining, live sperm will be white due to lack of staining. pH: Normally, semen has a pH ≥ 7.2. The pH varies with the acidic secretions of the prostate gland and the alkaline secretions of the seminal vesicles. Cases, the pH below 7 is often seen in aplastic seminal vesicles or ejaculatory duct obstruction. Evaluation of sperm motility: Criteria to evaluate sperm motility include PR motility (progressive motile sperm), NP motility (sperm motile but not progressive) Non-motile. White blood cell count: white blood cells in semen reflect inflammation, infection of the genital organs. Therefore, if the white blood cell count is large, it is possible that the patient has some sexually transmitted diseases. Sperm density: To count sperm concentration, semen should be diluted with a diluent and counted using a Neubauer counter. Evaluation of sperm shape: Sperm shape provides important information that helps predict conception rates if evaluated according to rigorous criteria. Sperm are normal when semen analysis shows normal head, neck, midsection and tail.

4. Normal semen test results

Based on the test factors, the test results are analyzed, the values ​​​​showing the normal semen sample include:
The volume of semen is more than 2ml. Sperm concentration greater than 15 million/ml. The white blood cell count is less than 1 million/ml.

The percentage of sperm alive in the semen sample is more than 58% Foreign cells or anti-antibodies in the sperm account for about 1 million/ml. 40% greater motility, progressive to 32% greater motility of total sperm. Sperm morphology is more than 4% of the sperm count normal. The pH is around 7.2 or higher. If the semen analysis results are normal, then the male fertility is normal. If abnormal values ​​appear, the test should be repeated 2 - 3 times, 2 - 3 weeks apart.
