Why do men with the "White Bone Demon" often become infertile?

According to data from the World Health Organization, the incidence of infertility among married couples of childbearing age is about 10%, and has increased to about 15% in recent years. Among more than 50% of infertile couples, the male has reproductive defects.

A survey conducted by the Women's Research Institute of a hospital in Guangzhou on 10,000 couples found that male infertility has reached 55%. Based on this calculation, there are at least 35 million male infertility patients in my country.

Male "White Bone Spirit" has reduced fertility

Hua (pseudonym) is a young and promising manager of a foreign company. He has been married for three years and is very satisfied with his married life. The only regret is that his wife, Ah Hong, has never been pregnant, which makes him very anxious. At first, Ah Hua thought it was his wife's problem. They went to the Reproductive Assisted Pregnancy Department of the Third Affiliated Hospital of Guangzhou Medical University for a comprehensive examination. When Ah Hua got the results, he was very surprised - his wife had no problems, but he had asthenospermia! Ah Hua was very confused: his sexual function was normal, why did he have asthenospermia and affect his fertility?

Ahua's case is not an isolated one. The incidence of infertility among urban couples in China has increased by 5 percentage points in the past 20 years. Andrology experts point out that the fertility problems of "white-bone spirit" men and "sedentary people" are not optimistic.

The threshold for infertility has been lowered

As far as the overall population is concerned, the reproductive function of Chinese men has been declining in recent years. Dr. Xuan Xujun from the Department of Urology at the Second Affiliated Hospital of Sun Yat-sen University said that more than a decade ago, the incidence of infertility among married couples was around 10%, but in recent years it has increased to around 15%.

Experts say that among the causes of infertility in both men and women, the male partner accounts for at least 50%. At the same time, the "threshold" of infertility has been forced to drop. "In the 1980s, the sperm survival rate had to reach 70% to be considered normal," he said, but now the sperm survival rate only needs to reach 50% to be considered normal.

Experts have pointed out that in terms of male infertility, the decline in sperm quantity and quality is particularly obvious, which is related to lifestyle and social environmental factors. Among the patients in the male infertility clinic, those suffering from prostatitis are more common. Chief Physician Xu Jianning also said that unmarried and childless men who use saunas, have varicocele, and have congenital vascular abnormalities can cause infertility.

In addition, Ureaplasma infection can cause male infertility. Guangzhou conducted an epidemiological survey on 427 infertile couples in Zengcheng District and compared the relevant data with 175 fertile couples. The results showed that the infection rate of Ureaplasma infection was significantly increased in the infertile group, and some other pathological changes related to fertility also showed significant differences between the two groups.

In recent years, Taiwan has discovered that gene defects are a new cause of male infertility. Defects in the AZFa gene located on the Y chromosome can cause male infertility. Testicular biopsies of patients showed that one had no sperm in his testicles, and another had low spermatogenesis, resulting in no sperm in his semen.

Infertility favors "White Bone Demon" men?

The so-called "White Bone Demon" refers to the "white-collar backbone elite" such as company backbones and senior managers aged 30 to 40. This group of people has high education, high social status, busy work, high pressure, easy to be nervous, and have many work and social activities. Long-term chronic mental stress, irregular eating, rich nightlife, lack of sleep, frequent active or passive smoking, drinking, etc., all of which lead to

Risk factors for erectile dysfunction (ED).

But why is it that a "white-bone demon" like Ah Hua, who has no problem with erections and a normal sex life, is also infertile? Experts believe that Ah Hua's weak sperm is caused by many reasons, but an unhealthy lifestyle is also a factor. For example, sitting for a long time and liking soft leather "executive chairs" will also affect fertility. When sitting for a long time, the crotch is in a state of blockage for a long time, and the local temperature rises, which will destroy the ability to produce sperm.
