Sperm has an extremely important role for male fertility, the fertilization ability of sperm is closely related to the normal form of sperm, the more the number of normal form of sperm, the stronger the fertilization ability. However, in recent years, the incidence of sperm malformation is increasing, seriously threatening the ability of male fertility, so how to reduce the rate of sperm malformation, the daily prevention of sperm malformation should be how to do? The main causes of sperm malformation are ageing, bad habits, environmental pollution and elevated sperm morphology testing standards. Many people have a less healthy lifestyle, staying up late, smoking and alcohol abuse for long periods of time, which are all causes of high sperm malformation rates. You must strengthen physical exercise in your daily life and go running outdoors often, which can improve the quality of sperm and also reduce sperm malformation. You can still try to conceive normally with sperm malformations, although a high sperm malformation rate will reduce the probability of sperm fertilization to some extent. If conception does not occur after one year of preparation, artificially assisted reproduction may be considered.
