1, a measure of sperm health
1, semen volume: normal ≥2ml. Too much when it is more than 7ml, not only reduces the sperm density, but also easily flows out of the yin meridian, resulting in a decrease in the total number of sperm, which is common in seminal vesiculitis. Less than 2ml means too little semen, but usually less than 1ml. At this time, the contact area between semen and female reproductive tract is small, or because of its viscosity, it is not conducive to sperm entering the woman's cervix, leading to infertility, which is common in severe accessory gland inflammation, low testosterone level, ejaculatory duct obstruction, retrograde ejaculation and so on.
2. Color: normally grayish white or yellowish. Milky white or yellow-green suggests inflammation of reproductive tract or accessory gonad; Microscopically, pink, red and red blood cells are bloody semen, which is common in inflammation of accessory gonads and posterior urethra, and occasionally seen in tuberculosis or tumors.
3.pH value: The normal pH value of semen is 7.2-7.8. Less than 72 is seen in ejaculatory duct obstruction or urine pollution; More than 7.8 is found in seminal vesicle inflammation or old specimens.
4. Liquefaction time: After normal semen is injected, it becomes gelatinous under the action of seminal vesicle coagulase, and after 15-30 minutes, it becomes liquid under the action of prostatic liquefying enzyme, which is semen liquefaction. It is abnormal that semen is not liquefied after 30 minutes of ejaculation.
5. Viscosity: The glass rod is contacted with liquefied semen and gently lifted to form semen filaments, the length of which is generally less than 2cm.
6, sperm count: generally expressed by the number of sperm per milliliter of semen. Normal count ≥20× 106/ml. Below this value, there are too few sperm, which can be seen in the dysfunction of spermatogenesis caused by various reasons, which can lead to low fertility or infertility due to the decrease of the chance of sperm entering the uterine cavity and fallopian tube. If the sperm count is more than 250× 106/ml, it means that there are too many sperm, and their motility can also lead to infertility.
7. Sperm morphology: Sperm with normal morphology ≥50%, otherwise it may lead to infertility.
8. Activity: Sperm moves forward rapidly in a straight line ≥50%.
9. Survival rate: Generally, it means that the live sperm is ≥50% at the time of examination within after ejaculation 1 hour. The common reasons leading to the decline of sperm motility and survival rate are hypogonadism, varicocele, ciliary stagnation syndrome caused by chronic respiratory infection, the existence of anti-sperm antibodies in semen or improper preservation of specimens.
10, white blood cells: white blood cells in normal semen "1× 106/ml. Leukocytosis indicates that there is infection in reproductive tract or accessory gonad.
2. Methods to improve sperm quality
1. Roommate frequency
In order to enhance the hit rate, some prospective parents reduce the number of sexual intercourse to improve sperm quality. In fact, if men only ejaculate 1-2 times a month, although the number of sperm will increase, the activity and survival rate of sperm will decrease, and the proportion of aged sperm will increase significantly, which is not conducive to pregnancy. Experts suggest having sex once a week 1~2 times, and women can increase it appropriately before and after ovulation.
2. Eat more foods rich in zinc.
Trace elements related to male fertility mainly include zinc, selenium, copper, calcium and magnesium. Zinc is an important element in the reproductive system, which is directly involved in the production, maturation, activation and capacitation of sperm.
Zinc deficiency will affect the development of reproductive organs and secondary sexual characteristics of adolescent men, reduce sperm mobility, affect sperm density, weaken the immune function of the body, and make men susceptible to infectious diseases such as prostatitis and epididymitis.
Therefore, men should eat more foods containing zinc. Plant foods rich in zinc mainly include beans, peanuts, millet, radish, Chinese cabbage, etc. Oyster is the best animal food, followed by beef, chicken liver, eggs, lamb chops and pork.
In order to ensure high-quality sperm, dad is not allowed to pay more attention to his life.
Prevent obesity
Male obesity will reduce androgen and increase estrogen in the body, hinder sperm production and affect sperm quality (what are the semen examination methods). In addition, obesity can also induce hypertension and diabetes, which may cause sexual dysfunction. So, for the sake of your angel baby, dads should shut up and take their legs away without permission!
4. Stay away from radiation and harmful substances
It has been proved that radiation has certain influence on human health. Low-dose radiation will affect the development of the body, while high-dose radiation will cause changes in testicular tissue structure, increase the abnormal rate of sperm and reduce the number and density of sperm.
In daily life, there are many radiation sources, such as microwave ovens, computers, televisions, air conditioners and mobile phones. These will all produce radiation. Therefore, men should minimize contact with radiation sources, such as not placing computers, televisions and other electrical appliances in the bedroom; Don't use electric blanket to keep warm; Try to avoid electromagnetic wave, nuclear radiation and X-ray irradiation.
Many chemical and biological factors can cause sperm malformation or chromosome abnormality, such as lead, benzene, xylene, gasoline, vinyl chloride, pesticides, herbicides, anesthetics and so on. , can lead to fetal malformation. If exposed to pesticides, pesticides, sulfur dioxide, copper, cadmium, mercury, zinc and other harmful substances. For a long time, from 6 months to 1 year after stopping contact, the residues in the body will generally be basically eliminated, which is not suitable for pregnancy.
5. Give "sperm" a stable rear.
In male reproductive organs, testis is the factory that produces sperm, epididymis is the warehouse that stores sperm, vas deferens is the transportation hub, spermatic artery and vein are the transportation lines for logistics supply, and prostatic fluid is the necessary solvent for transporting sperm.
When the father is not allowed to "front" and "fill", if the "back" falls, it will be a total loss. For example, sexually transmitted diseases such as syphilis and gonorrhea will affect the production, development and mobility of sperm, and diseases such as prostatitis, varicocele and tuberculosis will lead to infertility (what are the methods of semen examination). If you don't let dad suffer from genital inflammation, premature ejaculation, sexually transmitted diseases and other diseases, you must treat him as soon as possible.
6. Don't suffocate your "seed"
Sperm has strict requirements on temperature and must be below body temperature to develop normally. If the temperature is too high, it will kill sperm, or it will be detrimental to sperm growth, and even greatly reduce sperm vitality, leading to infertility (causes and treatment of low sperm survival rate). According to relevant statistics, a considerable number of male infertility is caused by the testicular temperature being higher than the normal temperature.
Therefore, we should try to avoid the factors that lead to the increase of testicular temperature, such as long-term cycling, sedentary, wearing tight jeans and so on. Sauna, steam bath and overheated hot water bath should be controlled or avoided during pregnancy.
