Men’s health can be seen from the color and smell of semen

　　What is the normal shape of semen?

　　According to experts, the characteristics of normal semen are very obvious. look male Whether the semen is normal or not, men can judge by themselves from the following aspects:

　　Semen volume: The normal amount of semen is 2 to 5 ml each time. If it is more than 7 ml, it is too much. At this time, not only sperm The density becomes lower, and it is easier to female Outflow from the vagina, resulting in a decrease in the total number of sperm, which is common in patients with seminal vesiculitis. If the total volume is less than 2 ml, the semen volume is small. If the total volume is less than 1.5 ml, it is too small, which can easily lead to infertility.

　　Color: Normal color is off-white or slightly yellow. If the semen appears milky white or yellow-green, it indicates inflammation of the male reproductive tract or accessory sex glands. If pink or red appears, or red blood cells can be seen under a microscope, it is bloody semen, which is common in patients with seminal vesiculitis and posterior urethral inflammation, and occasionally in patients with tuberculosis or tumors.

　　Time: After normal semen is ejaculated, it will turn into jelly under the action of seminal vesicle coagulation enzyme. After 15 to 30 minutes, it will turn into liquid under the action of prostate liquefaction enzyme, which is called semen liquefaction. If semen does not liquefy 30 minutes after ejaculation, it is abnormal.

　　Consistency: Touch the liquefied semen with a glass rod. After gently lifting it, semen strands will form. If the semen is normal, the semen length should be less than 2 cm.

　　When does a man’s sperm have the highest quality?

　　Males grow and develop later than females, their sexual maturity is delayed, and their physical strength and experience reach their peak later. Generally speaking, the golden age for women to have children is between the ages of 23 and 30. During this period, the number and quality of women’s eggs are much higher. So, at what age will the quality of men’s sperm reach its peak?

　　According to relatively independent surveys in the United States, Switzerland and other countries, men's sperm quality will reach its peak around the age of 30. At this time, men have relatively rich physical strength, energy, and life experience. The quality of genetic information contained in sperm is the best and the activity is the strongest.

　　The report pointed out: 30 to 35 years old is the best childbearing age for men, because men in this age group are in their prime. In addition to the internal advantages of excellent physical fitness, other external advantages, such as economic and career stability, superior material conditions for raising children, and mature psychological endurance. Although men have the ability to be fathers throughout their lives, from a eugenic perspective, it is better not to exceed the age of 35. The quality of a man's sperm reaches its peak at the age of 30, and then continues for 5 years until the age of 35, after which the quality declines.

　　Although male growth and development is finalized by the age of 25, male sperm has not reached its peak at this stage. Physical strength, experience, and social experience are all in the primary stage, and the DNA information contained in the sperm is not perfect. Therefore, the younger the male’s sperm, the better.
