Male infertility accounts for about 20% of infertility cases, of which more than 90% are due to sperm abnormalities. Semen analysis is a method of assessing sperm status so that timely interventions can be taken to protect male reproductive health.

1. What is semen analysis?

Semen analysis is a test based on semen samples to assess the quality of sperm, through indicators such as: quantity, motility, shape,... comply with World Health Organization (WHO) regulations. The WHO semen analysis values ​​are based on the scores of men of normal fertility when their wives have had children within 12 months. The semen analysis indexes are only meant to predict whether a man's fertility is high or low, but do not allow the conclusion to be infertile or not.
The results of the semen analysis along with the wife's reproductive health will help the doctor decide on the treatment plan for the infertile couple.

2. What does a semen analysis do?

Before the test, men are asked not to ejaculate for 2 to 3 days. The semen is then collected in a laboratory by masturbation or sexual intercourse using a specialized condom. In particular, semen should be analyzed within no more than 2 hours.
Some tests will require more than one test piece, possibly due to room temperature differences. The factors observed in semen are:
Total amount of semen (in ml). Standards for semen mixture (concentration, color, acidity). Semen concentration (sperm count/ml). Morphology (sperm shape and structure, which indicates sperm health). Motility (% of sperm moving forward). Total motile sperm count.

3. What is normal semen?

Normally, semen will be milky white or clear, thick and sticky (viscous), have a pH (acidity) around 7.8 to 8.0, and may contain white blood cells.
The following values ​​have been developed by the World Health Organization (WHO) for the analysis of normal semen:
Total volume > 2 ml. Concentration: At least 20 million sperm/ml. Morphology: At least 15% of normal spermatozoa. Motility: More than 50% of sperms are moving forward, or 25% are moving rapidly within 1 hour of ejaculation. WBC count: Less than 1 million/mL. Further analyzes (reaction between sperm and antibodies) showed less than 10% of the total spermatozoa.
However, in the case of low sperm count, it is not possible to say for sure that the man is infertile, because fertility depends on the female and many men with low sperm count are still able to conceive. normal reproduction. Similarly, it is also impossible to be certain that a man with a normal sperm count is fertile, because it is possible that the sperm lacks the ability to fertilize... Consult the results of semen analysis by specialists.
