Some men go to the hospital for examination when they are preparing for pregnancy and find that their semen is thin, which is medically known as semen non-liquefaction, which is a pathological phenomenon, and the fertilization rate of this semen will be lower, what should men do in the face of such a situation? Definition of semen thinning Semen thinning refers to semen thinning like water with milky white liquid, which is a kind of oligospermia. Generally, oligospermia is divided into idiopathic oligospermia, primary oligospermia and secondary oligospermia. Idiopathic oligospermia accounts for 11%-15% of the infertility population. Oligospermia is a condition in which the number of sperm in the semen is lower than that of normal fertile men. The International Health Organization stipulates that the sperm of men should not be less than 20 million per milliliter. If further subdivided, it is less than 20 million, more than 10 million, called mild oligospermia, if less than 10 million, more than 5 million, called moderate, if less than 5 million is called severe oligospermia, if only a few sperm can be found in the high-powered field of view, or only after centrifugation to see a few sperm is very little, called severe oligospermia. The formation process of thin semen Semen is stored in the body in a liquid state until it is ejaculated. When semen is ejaculated from the mouth of the penis, it immediately turns into a milky white or yellowish translucent jelly under the action of a protein-like substance secreted by the seminal vesicles, and this is the usual semen appearance that people see. After 5 to 30 minutes, with the participation of a hydrolase secreted by the prostate gland, semen starts to liquefy and gradually changes from jelly-like to thin water-like. This change in semen has a very important physiological significance: it starts out in a liquid state to facilitate the ejection of semen; immediately after ejaculation, it forms a gel, which facilitates the stay of semen in the vagina for a sufficient amount of time so that the sperm can get sufficient rest and energy; once liquefied, the sperm will have enough energy to swim quickly and go straight to the egg for a “blind date”. If inflammation occurs in the prostate or seminal vesicles, due to the lack of secretion or destruction of hydrolytic enzymes, the semen of these patients may not liquefy for a long time after ejaculation or incomplete liquefaction, and some may even take half an hour or even an hour to liquefy. This is a pathological phenomenon, medically known as semen non-liquefaction. The common factors leading to oligospermia are: idiopathic sperm reduction, long-term massive injection of androgens, due to the negative feedback effect to reduce hypothalamic gonadotropin-releasing hormone and lead to reduced gonadotropin secretion, resulting in a reduction or lack of sperm; drug effects, which can directly or indirectly affect sperm production, such as sulfonamides, furantadine, anserine, cyclophosphamide, aminopterin The sperm cell division can be delayed or stopped, or even irreversibly damaged; other factors, alcoholism, excessive smoking, drugs can inhibit sperm production; chronic prostatitis, varicocele, etc. can inhibit sperm production. The scrotum cools down the testicles in the varicocele, which is specifically used to produce sperm, is very sensitive to temperature changes, and the appropriate temperature for this area is 2 to 3°C lower than the human body temperature. Overheating inhibits the survival and maturation of sperm, causing a decrease in the number of sperm in semen or a decrease in motility. Suggestions: Infertility patients with high semen viscosity can, during intercourse during ovulation, eject several strands of semen into the vagina at the beginning of the contraction, and then withdraw the penis and discharge the second half of the semen outside the body, which reduces the viscosity of the semen and increases the chance of conception by facilitating the movement of sperm. This method of ejaculation is called the “step-by-step ejaculation method”. 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. There are also some tips to pay attention to, such as the clothes taken back from the dry cleaner is best to put a few days before wearing, because dry cleaning agents can affect male sexual function; 2, to develop good personal hygiene habits to prevent a variety of infectious diseases that endanger male fertility, such as mumps, sexually transmitted diseases, etc.; 3, the testicles are a very delicate organ, its optimal working temperature is about 1 degree lower than the human body temperature, if If the temperature is high, it will affect the production of sperm, so any factors that can raise the temperature of the testicles should be avoided. If you find any changes in the testicles that are different from the usual ones, such as swelling, hardening, unevenness, pain, etc., be sure to seek timely medical treatment.
