Declining sperm quality in the Age of 35

Age does affect the quality and quantity of sperm, but it turns out the decline can be started since he was 30 years old. Of course it will affect fertility.

Dr.Qian-Xi Zhu and his team from the Shanghai Institute of Planned Parenthood Research discovered the phenomenon in Chinese male seminal fluid. More than 1,000 men aged 20-60 years to donate their sperm to analyze the amount of semen produced, the sperm count, movement, and whether sperm was normal.

Compared with men aged 20-29 years, 35-year-old man has the ability to move lower.
Whereas the movement of sperm is essential to the process of egg fertilization. Interestingly decreased ability of sperm that has been started since the age of 30 years and continues to decline each year.

"Motalitas or swimming ability of sperm decreases with age and it will make them difficult to impregnate," said Andrew Wyrobek, a specialist in sperm from the Lawrence Berkeley National Laboratory who was not involved in this study.

The number of live sperm in semen is also less in men who are more mature. For example, in men aged 20-29 years approximately 73 percent of the sperm in seminal fluid samples were alive, while only 65 per cent of live sperm in the semen of men aged 50-60 years.

After the age of 30 years, sperm counts have also reduced the normal physical. Compared with men aged 20 years, those aged over 50 years has only 16 percent of sperm that appear normal.
