American Fox's news network reports recently, a latest research indicates, China's male seminal fluid quality fell back at the age of 30, the obvious decline appears especially 35 years old later. Zhu QianXi (transliteration) of Shanghai birth control scientific research institute The doctor has carried on research to 1000 Chinese men among 20 years old - 60 years old. He has analyzed male producing amount of seminal fluid, content of sperm, activity of the sperm and appearance of sperm in the seminal fluid,etc., the result reveals, compared with 20 years old -29 years old age groups, sperm's content of seminal fluid of the group of 35 years old is less, and sperm's activity is from beginning to drop at the age of 30. In addition, the quantity of living sperm decreases progressively with age in the seminal fluid. At 20 years old - group of 29 years old, the proportion of living sperm accounts for 73% in the seminal fluid; At 50 years old - group of 60 years old, this only 65% proportions. Study to find, 30 years old later, the quantity of sperm with normal appearance begins to reduce too at the same time, men of the group of 50 years old than the man reduction 16% of the group of 20 years, but increase with the continuation of age, male sperm's number and seminal fluid quantity will not be changed too big. Researchers say, sperm's quantity means that it is difficult to make women become pregnant, this just weighs an index of fecundity. But they call upon men to form the habits and customs well, it is healthy to pay attention to protecting sperms. (Feng GuoChuan)
