We know that Neocoronavirus can attack the respiratory and immune systems, causing symptoms such as coughing and difficulty breathing, but you may not know that Neocoronavirus also attacks the reproductive system, causing testicular damage in men. The novel coronavirus binds to the host cell angiotensin-converting enzyme 2 (ACE2) through the stinger glycoprotein (S protein) to invade the cell and cause tissue damage. In addition to the lung, many other organs in the body also express ACE2, such as the testis, small intestine, kidney, heart, and thyroid. Among them, the testis expresses a large amount of ACE2, mainly in testicular spermatogonia, supporting cells and mesenchymal cells, all of which are closely related to male reproductive function. Therefore, men who are infected by the novel coronavirus should go to the hospital for a good sperm activity test. In addition to neocoronavirus, obesity can also affect fertility. Male obesity can cause sperm inactivation, resulting in low conception rates and embryos prone to miscarriage. Overweight and obese people not only have less semen volume (sperm count), but also have few normal sperm count. The chances of an obese man having less sperm are more than 60%, and the chances of him having abnormal sperm are more than 40%. Obese people often have sexual dysfunction, due to more body fat, but also easy to accumulate in the scrotum area, fat has a thermal insulation effect, may prevent the scrotum heat, if the testicular temperature is too high, it will affect sperm activity or reduce secretion. Too much fat can also affect the metabolic function of sex hormones, which may lead to reduced sperm production or decreased sperm quality. In addition, if there is too much fat in the scrotum area, it will also compress the vas deferens, or blood vessels, which will cause ischemia or blood flow to the testes and affect sperm production. Obesity can also cause diseases such as diabetes or hypertension. For example, high glucose levels in the blood of diabetic patients can damage the DNA in the sperm, thus affecting fertility. Obesity not only affects male fertility, but can also lead to female infertility. Obesity is a metabolic disease that can affect the secretion of normal hormone levels in the body, which can lead to menstrual disorders and even polycystic ovary syndrome in women. Not only that, obese women have an increased risk of ovarian and uterine cancer, which is the number one cancer that kills women, than normal sized women! Therefore, female obesity not only affects the aesthetics of the body, but also brings infertility and even death. In the face of various threats caused by obesity to the body, only weight loss can completely get rid of. The only way to lose weight is to control your mouth and open your legs. Control the diet and moderate exercise, to the body caused by poor energy, intake than consumption of less, so that naturally thin. And today we are going to introduce another way to lose weight, that is weight loss surgery. Weight loss surgery is the only internationally recognized long-term effective and safe method of weight loss, and after seventy years of development, one pound has now become a mature, safe and routine method of weight loss. Unlike liposuction, bariatric surgery is a rigorous surgical procedure that requires multidisciplinary involvement. The surgical principle of bariatric surgery is to achieve weight loss by altering the digestive tract and thus the absorption of food. Bariatric surgery not only leads to successful weight loss, but also serves the purpose of treating the many metabolic diseases that accompany obesity. In the face of obesity, we choose the right weight loss method to make ourselves beautiful and gain health at the same time.
