The sperm is responsible for the important task of passing on the family name to the next generation, and high quality sperm is related to whether a man can conceive a healthy and lovely baby. The quality, quantity and mobility of male sperm will affect the health of the next generation, so it is important for men who want to have good fertility to have their sperm quality checked in advance. How do I know if I have a semen abnormality? The term “semen abnormality” refers to a condition in which the total number of sperm, viability, motility, malformation rate and liquefaction time in a man’s semen are abnormal. The cause is both congenital and acquired, and is a disorder of the sperm production process. Semen abnormalities are divided into two categories: semen abnormalities and sperm abnormalities, the former referring to the amount of semen, color abnormalities, and quality abnormalities, and the latter referring to the amount of sperm, quality abnormalities, and malformations. The classification is as follows: 1. Semen increase and semen decrease Generally, the amount of semen normally discharged at one time is 2 to 6 ml, less than 1.5 ml is semen decrease, more than 6 ml is semen increase, and semen increase is not equal to sperm increase. If the isolated semen does not liquefy or still contains liquefied agglomerates after 60 minutes at room temperature (22-25 degrees Celsius), it is called “semen non-liquefaction”, which affects the agglutination or braking of sperm and slows down or inhibits the normal movement of sperm. The number of sperm in the semen is lower than that of a normal, healthy, fertile man. As the quality of human sperm has tended to decline in recent years with the environment, pollution from estrogen-like toxins and other factors. Nowadays, sperm count less than 20 million per ml is considered as oligospermia. However, clinically it is often accompanied by low sperm viability, poor forward motion and high sperm malformation rate, which is called oligozoospermia. 4, azoospermia Azoospermia refers to the absence of sperm after centrifugal sedimentation of ejaculated semen and microscopic examination. 5, low sperm motility and dead sperm syndrome Within 1h after sperm discharge, viable sperm should be above 70%, if there are viable sperm below 50% as abnormal, called sperm motility hypo, also known as weak sperm. If the sperm is completely inactive, it is called dead sperm. Low sperm motility and dead sperm is one of the important causes of male infertility. 6, hematospermia The semen mixed with blood is hematospermia. It is usually pink, red, brownish red or with blood. Depending on the nature of the lesion and the amount of blood it contains, it can be seen as hematosperm, blood clots and microscopic hematosperm. A reminder: The initial prototype of a child is formed by the union of a sperm and an egg. Then, a man needs an exceptionally strong sperm to achieve his fertility purpose. Normal sperm and semen is a prerequisite to ensure that men have normal fertility, and once abnormalities occur, it will cast a thick shadow over fertility. Therefore, friends should pay attention to this situation and go to a regular hospital as soon as possible to have their male sperm quality checked. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. Routine semen examination includes semen volume, semen color, acidity, liquefaction time, viscosity, sperm count, proportion of normal sperm, sperm motility, survival rate and the number of white blood cells in semen. Item 2: Analysis of chromosomal factors. When the sperm count is too low, the motility is too low, the sperm is heavily deformed or there is no sperm present at all, it is important to think if it is a chromosomal problem. In men with underdeveloped secondary sex characteristics or low sexual function or with few or no sperm despite normal testicular development and secondary sex characteristics development, further examination of autosomes should be performed. Item 3: Checking gonadotropins. Performing gonadotropin measurement is important to determine the functional status of the hypothalamic-pituitary-gonadal axis in men. By observing the level of folliculopoietin values, the degree of testicular development or damage can be known. Normally, the performance of spermatogenesis in men’s varicocele is generally facilitated by the secretion of folliculopoietin from the pituitary gland. Item 4: Do special item tests. Anti-sperm antibody test. Those who are positive for antisperm antibodies are often accompanied by other problems, and some are closely related to this positive. Warm reminder: male semen abnormalities lead to infertility accounted for a certain proportion, which is currently leading to a large aspect of male fertility decline, should cause people to pay attention to, for those couples who have sex after marriage, more than a year without contraception, more attention should be paid.
