Men to middle age, physical strength, energy have declined, sex life is not as enthusiastic as when young, most people attribute this phenomenon to the increased pressure of life, physical quality of decline, or the relationship between the couple. It is true that all these conditions can have an impact on sex life, but they also miss the point that obesity is also one of the most important factors affecting sex life. Our fat cells are also hormone-secreting cells that also have an effect on other hormones. When men are too obese, their bodies secrete more estrogen. Men’s libido is very much related to the amount of androgens in their blood, so when estrogen production increases and androgens decrease, their libido will also decrease. At the same time, obesity also leads to lower testosterone production and increased estradiol production, causing erectile dysfunction. And excessive fat near the testicles will cause the temperature of the scrotum to rise, which directly affects the spermatogenic ability of the testicles, and the sperm activity rate will decrease, which can seriously cause infertility. Therefore, weight loss is a very necessary thing for gay men at any time, and the sooner you lose weight, the better. 35 years old and above may not be able to meet the long-term weight loss needs of sleeve gastric surgery alone, and need to be combined with jejunostomy or direct gastric bypass, which can limit the absorption of the effect will be more ideal, while those relatively young fat friends, if they are more obedient, only limit the amount of diet sleeve gastric surgery.
