Before the age of 30, sperm is the best. Experts say it is not recommended to have children too late

Recently, Sohu. com conducted a week long survey on male sperm health issues and published the 2012 White Paper on the Quality of Chinese Male Sperm.

According to the survey results, nearly 1/4 of netizens do not know that sperm quality is the best between the ages of 20 and 29, 40% of netizens do not know that sperm has a special odor like gardenia, 11% of netizens need to abstain for 2 to 7 days before undergoing semen testing, and 26% of netizens do not know the liquefaction time of semen. Clinical experts say that semen non liquefaction syndrome accounts for about 20% of male infertility causes.

Many netizens believe that radiation can cause problems with male sperm quality, but current research shows that computer and mobile phone radiation has almost no effect on sperm quality. Guo Jun, director of the andrology department of Xiyuan Hospital of the China Academy of Chinese Medical Sciences, pointed out that because mobile phones or computers have not been developed for a long time, they do not affect or cannot detect the impact on sperm quality, which does not mean that there will be no impact in the future. As for the future situation, it is still unknown.

However, Guo Jun told reporters that semen quality is an important criterion for evaluating male fertility. According to the survey results, some men have misconceptions about semen. Therefore, male friends can not only pay more attention to their own health status, but also self check semen quality through some simple methods to provide reference for further medical treatment. 1. Look at how much. The normal discharge of semen is 2-6 milliliters, and the amount of semen is mostly related to the frequency of ejaculation. 2. Look at the color. The normal semen color is gray white or milky white. 3. Smell the odor. Fresh semen has a special odor, similar to that of gardenia flowers. If there is a noticeable odor, consider whether it is co infected. 4. Identify liquefaction. The newly ejaculated semen is in a thick gelatinous state, which usually liquefies within 5-30 minutes, becoming a thin and transparent state similar to water.

Zhang Zhichao, deputy chief physician of the Men's Center at Peking University Hospital, said that testicles are afraid of heat, and male friends must pay attention to this characteristic. To maintain semen quality and improve fertility, the first step is to quit drinking and avoid alcohol before planning to have a child. Secondly, it is important to avoid staying in high temperature environments for too long. In addition, it should be noted not to sit for long periods of time, preferably not exceeding an hour, as this may affect the health of the testicles.

Zhang Zhichao believes that the reproductive age of the couple is the key to raising a healthy baby, and the quality of childbirth gradually decreases after the age of 30. Late childbirth is not advocated. In addition, male friends should ensure a healthy body, maintain a good mood, maintain sufficient sleep, have a balanced diet and nutrition in their daily lives, and most importantly, change unhealthy lifestyle habits.
