Core tip: Teratozoospermia means less than 50% of normal-shaped sperm, that is, more than 50% of abnormal sperm in semen. Experts from Qingdao Andrology Research Institute said that the so-called abnormal sperm refers to poorly developed sperm. Teratozoospermia refers to one of the common causes of male infertility caused by teratozoospermia in men of reproductive age. Experts from Qingdao Andrology Research Institute said that clinically, teratozoospermia often coexists with oligozoospermia and asthenozoospermia. If the three coexist, we also call it oligoasthenozoospermia. Abnormal sperm refers to morphological variations of the head, body, and tail. Head malformations include huge heads, amorphous heads, and double heads; body malformations include thick, broken, and incomplete bodies; tail malformations include curly tails, double tails, and missing tails. Wait. The so-called abnormal sperm refers to poorly developed sperm. Teratozoospermia refers to a man of childbearing age. If his sperm density is more than 20 million per milliliter in two consecutive semen analyses, A-grade sperm is a straight line. If the sperm with motile sperm is greater than or equal to 25%, but if the sperm with normal head shape is less than 30%, it can be diagnosed as teratozoospermia. We know that sperm morphology is closely related to sperm movement and sperm fertilization ability. The more normal sperm there are, the higher the fertilization rate. On the contrary, the fertilization rate is low. Therefore, teratozoospermia is one of the common causes of male infertility. , however, clinically, teratozoospermia often coexists with oligoasthenozoospermia and asthenozoospermia. If the three coexist, we also call it oligoasthenospermia. Causes of teratozoospermia include genitourinary tract infection, orchitis complicated by mumps, epididymal tuberculosis, varicocele, etc. These diseases can affect the quality of sperm; the use of hormones or certain chemical drugs, such as anti-cancer drugs , reserpine, Malilan, furans, etc., can make sperm development immature; gonads exposed to radiation can cause sperm mutations; long-term local high fever in the scrotum and long-term alcohol abuse can cause sperm distortion. If more than 70% of the sperm are abnormal, a chromosomal examination should be carried out. If there is a chromosomal disease, treatment will be more difficult. When there is Mycoplasma or Chlamydia infection in semen, sperm motility and sperm density will decrease, and abnormal sperm will increase. Among the indicators of routine semen examination, the malformation rate is an important diagnostic data and an indicator to determine whether a man has normal fertility and eugenics. Negative, the morphology of sperm in normal semen plays a very important role. Some men think that the sperm count is normal and the motility and motility rate are up to standard. In fact, it also depends on whether the sperm morphology in the semen is normal. If the sperm morphology is abnormal, that is, more than 20% of the sperm are deformed, it will affect the male's reproductive ability, and of course it will also affect prenatal and postnatal care. What needs special emphasis is that some couples do not pay attention to the problem of sperm abnormalities and often think that as long as they can get pregnant, it must be fertilized by good sperm and it will not affect prenatal and postnatal care. In fact, this understanding is not comprehensive. We know that if there are too many sperm abnormalities, there will be little room for selection during fertilization. Even if fertilization occurs, it will definitely be in a low-quality and low-level fertilization state, which is very detrimental to eugenics and may lead to miscarriage, premature birth, and fetal loss. The probability of anomalies and other anomalies occurring increases. Sperm morphology examination methods mainly include the following aspects: After smearing and staining the semen, observe the sperm morphology under a microscope: the morphology of normal sperm. The head is oval in front, flat on the side, and the tail is long and curved, like a tadpole. The head of sperm can have four different shapes: large head, small head, round head or pointed head, but all are normal; the shape of immature sperm. Immature sperm, also called immature sperm, have extremely small heads, or have additional caps, or have appendages on their bodies. If the proportion of such sperm is too high, it will directly lead to a decrease in fertility; the state of aging sperm. The head is darkly colored with many spots in between, but there are also heads that are not colored at all, like vacuoles. Experts from the Qingdao Andrology Institute said that the classification of abnormal sperm mainly includes the following aspects: One or more of the three parts of the sperm's head, body and tail have morphological variations. Head deformity may have a huge head or the nucleus and cytoplasm are inverted, showing a mushroom-like head, or one sperm and two heads; body deformity: the body is extremely large and thick or wedge-shaped or triangular; tail deformity: a thick tail or a thick and bifurcated tail Or double tail; mixed head and body abnormal sperm: the head and body are both too large or mixed and elongated, and the nucleus becomes elongated and other deformities. If the sum of all kinds of abnormal sperm does not exceed 20% of the total number of sperm, it can be regarded as a normal phenomenon. In short, when there are too many immature sperm, senescent sperm and abnormal sperm, they will affect normal fertilization and have a negative impact on fertility. Semen contains a small number of white blood cells, and an average of no more than 5 white blood cells in a high-power field of view can be considered normal. If there are too many, it can also affect fertility. Adult male fertility is directly proportional to sperm number and sperm motility, and inversely proportional to the abnormal sperm rate. When the sperm morphology is abnormal and exceeds the standard, treatment is also required. Even if the sperm motility, motility rate, and number are normal, relevant treatment is still required. There are many reasons for abnormal sperm morphology, including infection, immunity and other factors. Abnormal sperm morphology not only easily leads to a decrease in male fertility, but also causes miscarriage, abnormal fetal development, etc. after pregnancy. During treatment, treatment should be carried out according to the cause. After the cause is eliminated, the quality of sperm can be mainly improved. The number, vitality and viability of sperm will be significantly improved, and the morphology of sperm will also become normal.

Experts remind: In view of the cause of the disease, we must comprehensively understand the patient's disease process, find out the triggering causes, and actively provide psychological guidance to help patients eliminate ideological obstacles and increase their confidence in recovery. For any disease, we must achieve early prevention, early detection, and early recovery. treat. The condition of the patient is different depending on the patient's physical health.
