At the 15th anniversary celebration of the Chinese Medical Association’s branch of male medicine and the 5th Chinese Men’s Forum, experts pointed out that the number of infertile men in China is increasing year by year, with a prevalence rate of 10% to 12%. Data from a clinical study shows that the proportion of azoospermia, oligospermia and weak sperm in male infertility patients has increased over the past five years; sperm density, sperm vitality and sperm viability have all shown a declining trend. Experts believe that infertility is no longer just a health problem, but a social problem. The Institute of Science and Technology of the National Population and Family Planning Commission found, after analyzing the sperm of a total of 11,726 men in 39 cities (counties) between 1981 and 1996, that the semen quality of men in China is declining at a rate of 1% per year, a drop of more than 40%. The semen data of 51,258 male infertility patients from 2004 to 2008 were analyzed and found that: the proportion of patients with azoospermia increased from 6% to 10%, those with oligospermia increased from 60% to 85%, and those with weak sperm increased from 78% to 92%, with the largest proportion of patients with weak sperm; the sperm viability rate decreased from 47.27% in 2004 to 32.97% in 2008. Experts pointed out that the incidence of infertility in couples of childbearing age in industrialized countries has increased from 7% to 8% in the 1960s to 15% to 20% in recent years, and the incidence of male infertility in China is 10% to 12%. Among them, about 70% of male infertility has no clear cause except for genetic factors, gonadal infections, acquired testicular damage, immunological factors and other clear causes. Experts believe that the culprit for the decline in male semen quality is the adverse effects of industrialization. In addition, unhealthy lifestyle is also one of the “culprits” that lead to the decline of male sperm count. Experts suggest that men should start changing their unhealthy lifestyles immediately to protect their sperm.
