Since 2007, China has entered the era of “leftover men”; by 2020, there will be about 24 million more men than women in China. Sunshine experts pointed out that men who are single for a long time will lead to frequent psychological and physical problems, and become a high incidence of male diseases. What are the reasons? Let’s find out! The “leftover men” have the same physiological needs as normal people, so how do the “leftover men” solve their physiological needs? The survey shows that they have fixed sexual partners and normal sexual behavior accounted for only 17.6%; masturbation accounted for 31.4%, long-term sexual repression accounted for 21.6%, one-night stands accounted for 9.8%, commercial sexual activities accounted for 7.8%, with 3.9%, other 7.8%. From this set of data can be seen, “leftover men” less than 20% of the normal sexual behavior, sexual repression in the torture of “leftover men”. In this regard, experts say that men’s long-term sexual repression and irregular sex life can lead to a decline in sexual function, and can also lead to prostatitis, orchitis, epididymitis and other diseases. It is especially important to emphasize that unstable multiple sexual partners and trade sexual activity are currently the main risk factors for the spread of STDs, AIDS and other diseases after drug abuse. Late marriage can cause a high incidence of male infertility “The presence of a large number of leftover men makes late marriage a very common phenomenon. Experts warn that men of the right age should get married before it’s too late, because men who marry late are more likely to suffer from male infertility. With the increasing severity of environmental pollution, the increasing pressure of survival, the impact of poor lifestyle, the incidence of infertility in China is on the rise, the average of every 10 couples in a couple can not have children. The impact of toxic and harmful gases on male sperm far exceeds the impact on eggs, so that the number of sperm, the quality has decreased, the proportion of infertility caused by the male side has increased significantly, from the previous 20% to 40%, almost doubled, and the later the marriage, the higher the incidence of infertility. Men may wish to “start a family before establishing a career” “leftover men” phenomenon has become an important factor in threatening the health of future generations and family happiness, in response to this phenomenon, experts suggest: in order to the health of future generations, in order to family happiness, men may wish to “Start a family first, then establish a career”. ”Start a family first, then establish a career” is completely feasible, because with the growth of age, “leftover men” will gradually become mature, rational, more comprehensive thinking about life, society, family, attitude toward life will be more serious and responsible. Therefore, as long as you can overcome the psychological barriers, you will be able to get a sincere and stable love. In this regard, the “leftover men” must not lose confidence.
