What Factors Affect Sperm Analysis Results?

Sperm morphology analysis refers to the scientific method of observing and analyzing sperm morphology through the method of smear staining to understand the proportion of normal sperm and mutant sperm in the physiological and pathological range to reflect male fertility.

Analysis methods

With the development of medical science,

Standard semen analysis: First, attention should be paid to the collection and transfer of specimens. Semen collection must be abstinent for 3-5 days. Patients should be masturbated to take specimens in the examination room and place them in clean, dry jars. Because the range of semen index changes is large, it can not be judged from only one test, so it is appropriate to perform 2-3 semen inspections at an interval of 1-2 weeks.

Check the semen liquefaction: When the human semen is coagulated immediately after being ejected, the semen will change from the coagulated state to the liquefied state after being left in a water bath at 37 ° C for 5-20 minutes.

Check the color of the semen: The normal color of the semen is translucent off-white. When the reproductive tract infection is a large number of white blood cells in the semen, the semen sample may be white or pale yellow. When there are bleeding lesions in the genital tract, the semen can be red or pink. Hematospermia may be the cause of male infertility.

Check the amount of semen: Generally, the amount of ejaculation in normal men is about 2-6ml. The amount of ejaculation has a certain relationship with the frequency of ejaculation. Semen volume less than 1ml / time is called semen volume reduction, semen volume greater than 6ml / time is called excessive semen volume, these are abnormal conditions.

Check the semen pH: The normal range of semen pH is between 7.0 and 7.6. The semen pH should be measured immediately after the semen is liquefied, otherwise the semen pH measurement results will be affected because the semen is left for a long time.

Check sperm motility and vitality: varicocele, prostatitis, etc. may affect sperm motility. Sperm viability is counted as a percentage of active sperm. All sperm with motile tails are active sperm. Less than 50% is low sperm motility.

Check sperm density: Sperm density is closely related to fertility. Generally, oligozoospermia is considered when the sperm density is less than 20 million / ml. No sperm was found in semen as azoospermia.
