To conceive a quality baby, you need to start by developing quality sperm. We often only notice the role of the woman in the conception of the offspring because the fertilization and development and growth of the egg takes place in the mother’s body, so we think that the mother has a great responsibility. However, we do not know that the role of the father is also very important. In addition to the egg cell, the quantity, quality and motility of the sperm play an important role in the completion of fertilization, with the quality of the sperm being particularly important. In addition, the strength of the sperm in the general perception, seems to be closely related to the male sexual ability, even if always confident of their ability in bed, once encountered difficulties to make the other half of the embarrassing situation of conception, it is inevitable that the ambition will be greatly reduced, the masculine style lost! The sperm is actually quite sensitive and fragile, from the various external or internal stimuli in life, may reduce its vitality, or even kill its vitality. The seven sperm killers: 1, overworked, long-distance cycling: perineum and scrotum for a long time in a squeezed state, on the one hand, affect the secretion of the prostate and seminal vesicle glands. On the other hand, the testicles are in a state of prolonged ischemia or even minor trauma. All of these can affect the quality of semen. 2, bad psychological state: excessive psychological stress, prolonged overstressed state, depression, anxiety, pessimism and sadness can lead to a decrease in semen quality, sperm dysfunction and a lower conception rate. 3, sedentary: sedentary is currently the most common bad habits, sedentary for more than 8 hours a day for more than a year, semen quality decreased significantly. For those who continue for more than three years, the low quality of semen is about 46%. 4, smoking: cigarettes contain mutagenic substances that cause mutagenesis in sperm, which can not only cause damage to somatic genetic material, but can also affect the maturation and proliferation of germ cells through the blood-testis barrier, leading to an increase in sperm DNA strand breaks and higher sperm malformation rates. 5, alcohol abuse: ethanol has a significant damaging effect on sperm density, vitality, viability, morphology and fertilization ability, long-term heavy drinking can lead to alcoholism, causing testicular atrophy, loss of libido, increased sperm deformity, total number and density reduction, the harm caused by alcohol consumption before the age of 18 is significantly greater than that of adults who drink after the age of 18. 6, improper frequency of sexual life: the appropriate frequency of sexual intercourse is not only beneficial to the physical health and psychological balance of both men and women, but also improve the quality of semen, increasing the chances of conception. However, too frequent sexual intercourse will reduce the density and number of sperm, affecting spousal conception. 7, improper diet: partial diet, it is possible to make the generation of sperm necessary substances lack, resulting in sperm quantity and quality is reduced. Prolonged zinc/selenium deficiency can lead to reduced male fertility, reduced sperm count, increased malformation rate and increased risk of malformation in embryos. Nine tricks to optimize sperm quality: 1. Participate in more exercise: Studies have shown that excessive obesity in the male body can lead to increased temperature in the groin, which impairs sperm growth and thus leads to infertility. Therefore, weight control within the standard range can improve the quality of sperm. 2, less to sauna, steam bath: high temperature steam bath directly harm sperm, but also inhibit sperm production. 3, quit smoking: data show that 44% of people believe that smoking is the most important factor in the decline of sperm count, so it is imperative to quit smoking. 5, say no to narcotics: narcotics, drugs, etc. are also very harmful to sperm, and will last a long time. 6, relax your mind. Mental stress also has a negative impact on sperm growth. So men should do something to relax themselves, such as walking, bathing, etc., and then enjoy their sex life. 7, put the phone in the top pocket: cell phones in the pants pocket, laptops on the knee, wearing tight pants can raise the temperature of the scrotum and hurt sperm, so you should put the phone in the top pocket. 8, eat more green vegetables: green vegetables contain vitamin C, vitamin E, zinc, selenium and other components that are conducive to sperm growth. Nuts and fish are rich in omega 3 fatty acids, which should also be eaten more often to facilitate sperm cell growth. 9, often to the hospital physical examination: germ infection is also an important factor in male infertility, should often go to the physician, to receive mycoplasma, prostate related examination.
