What is the role of sperm?

Sperm is a male germ cell produced by the testis. It plays a vital role in reproduction. Its main role is to combine with the egg to form a fertilized egg, which develops into an embryo and fetus. This process is fundamental to human reproduction and is a critical step in the continuation of life. Sperm also secrete substances that help maintain the normal functioning of the male reproductive system. It should be noted that sperm quality and quantity are critical to reproductive health. A number of factors, such as lifestyle, environmental pollutants and genetic factors, can affect sperm quality. Therefore, maintaining a healthy lifestyle, such as a balanced diet, moderate exercise and reducing smoking and alcohol consumption, is important to maintain reproductive health. Sperm is also associated with a number of male reproductive system diseases, such as sperm abnormalities, low sperm motility and abnormal sperm count. These diseases may lead to male infertility or fertility problems. If these problems exist, seek medical attention, relevant examinations and treatment.Generally speaking, sperm plays an irreplaceable role in the reproductive process and is of great significance to male reproductive health and reproduction.
