Sperm quality is one of the important indicators to measure the strength of male fertility. However, in recent years, more and more men are facing the problem of declining sperm quality over time. Therefore, it is important for male friends who want to pass on their sperm health to future generations.
After all, sperm is a carrier of DNA, and its quality is directly related to the success of fertility. Therefore, men need to carefully evaluate their sperm quality to ensure that they have sufficient fertility.
How can I tell if my sperm is up to standard? ColorThe color of normal sperm is grayish-white, and it may appear pale yellow or milky white when it has not been used for a long time. If the green color appears, it may be due to an infection of the genital tract or accessory gonads. In addition, redness (hematospermia) may be a symptom of seminal vesiculitis, cancer, tuberculosis and other diseases.
AmountNormal ** is a viscous liquid mixture made up of sperm and seminal plasma. For healthy adult males, the amount of ejaculation per excretionUsually between 2 5 ml。If the amount of semen dischargedLess than 15 ml or more than 8 ml, which may suggest a reproductive health problem. WhenThe amount of sperm excreted at a time is less than 0at 5 ml, which is known as oligospermia; And the absence of ** at all is called azoospermia.
These two conditions, azoospermia and sperm reduction, are the main causes of male infertility. These conditions may be related to diseases of the prostate or seminal vesicles, congenital ureteral occlusion or inflammatory strictures, and problems such as retrograde ejaculation.
Sperm countSperm count, i.e. the density of sperm per milliliter**, is an important indicator of male fertility.
In general, men of normal fertility have 0 sperm per milliliter**600 million to 1between 500 million, and sometimes it may even reach 200 million. The total number of sperm expelled in a single session is usually more than 300 million. However, there is a great deal of individual variation in sperm count, and the sperm count of the same person can also vary at different times.
Therefore, assessing the total number of sperm excreted at a time** has greater diagnostic value than checking sperm count alone. When the sperm density is too high, i.e. more than 2 per milliliterAt 500 million, this is called polyspermia. Excessive sperm density may affect the motility of sperm, and even if pregnancy is successful, miscarriage is likely to occur, mainly due to the quality of the sperm itself.
SmellNormal** has a special fishy smell, which is emitted by prostatic fluid, and this fishy smell** is a component of prostatic fluid.
pH**Normally weakly alkaline, pH 77～8.5. Excessive acid or alkali may affect the activity and metabolism of sperm, which is the main cause of sperm death (necrospermia).
ConsistencyNormally fresh** is liquid, quickly becomes a viscous peptone-like semi-fluid after discharge, and becomes liquid again after 5 to 30 minutes. If it does not liquefy for 30 minutes, it can be called **non-liquefaction, which will affect sperm motility and need to be performed**. Seen in: deficiency or deficiency of certain enzymes secreted by the prostate, and can also occur in tuberculosis of the reproductive system, which may affect fertility.
Forward athletic abilityThis is an indicator to detect sperm motility, that is, whether the sperm will move and swim fast or not, which is related to whether the sperm can reach the uterus, fallopian tubes and combine with the egg. If it is less than 32%, it is asthenospermia.
MorphologyAffected by various factors, normal sperm and abnormal sperm have their own proportions, such as head malformation, tail malformation, etc. According to the World Health Organization, if the proportion of sperm in normal form is less than 4%, it can be considered teratospermia. Too many malformed sperm can affect male fertility.
