What factors will affect the sperm vitality of men? Is regular exercise good for male reproductive function

Although the sperm is small, it has a great ability of transection. It penetrates cervical mucus and swims into the female fallopian tube. Healthy adult men produce hundreds of millions of sperm every time they ejaculate, but not all sperm are brave and good at fighting. The number of sperm is amazing, but life is fragile. According to Guo Jun, chief doctor of the andrology department of Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine, sperm motility is commonly used in medicine to evaluate semen quality, mainly referring to the proportion of progressive sperm in semen. Sperm vitality is mainly affected by the following aspects.

Age. Generally speaking, the vitality of male sperm changes in a parabola with the growth of age, and 20-40 years old is the best time for vitality, that is, the golden period of male fertility. After the age of 40, the sperm vitality of men decreases at a rate of 0.7% every year, and abnormal sperm increases. Over the age of 60, 85% of sperm may be abnormal.

Exercise. Research shows that male obesity will lead to the rise of inguinal temperature and damage sperm growth. Proper exercise can help improve sperm vitality, balance body hormone levels, especially maintain the secretion level of male hormones. However, vigorous exercise such as marathon and long-distance cycling may affect the growth environment of sperm.

Temperature. The habit of wearing tights, steaming sauna, taking a bath, and putting notebooks on your feet for a long time will lead to poor local heat dissipation, increased scrotal temperature, and decreased sperm production and vitality.
