What is oligospermia, weak sperm and deformed spermatozoa? Diagnosis of oligospermia: having a sperm density less than 15×106Mml but more than 0.0×106Mml without meeting other diagnoses. Diagnosis of weak spermatozoa: there is normal sperm density but the percentage of forward-moving sperm is lower than the laboratory reference value (forward-moving sperm a+b ≥ 32%) and it is not consistent with other diagnoses. Teratozoospermia: <4% normal sperm morphology. Learn to read the semen test analysis report The most important test to understand male fertility is semen analysis, which mainly analyzes the number and functional status of sperm. Many male patients are often dizzy and confused by the large pile of data when they get the lab report. It is very important to learn to understand semen labs. The amount of semen in adult men should not be less than 1.5 ml. The freshly ejaculated semen is solidified and becomes thin and liquid after 5-30 minutes, which is called liquefaction. If it is not liquefied in more than 60 minutes, it greatly limits the sperm's mobility and may affect the sperm's ability to conceive. The pH of semen is generally slightly alkaline in the center, with a pH value of 7.2-8.0. Excessive acidity or alkalinity is not conducive to the survival or physiological function of sperm. If the density of sperm is less than 15×106/ml or the total number of sperm is less than 39×106 per ejaculation, it is called oligosperm state and is not easy to conceive. It is better to check the number of motile sperm above 40%, and the more the better, among which the most likely to have the ability to conceive is forward-moving sperm, and the more the better, generally above 32%. According to the strict sperm morphological analysis, the proportion of normal form sperm should be greater than 4% or more. Total white blood cell count is at <1.0×106/ml.
