1.As a male, is it necessary to have a preconception test? A: According to the WHO survey, 15% of couples of childbearing age have infertility problems, while in some areas of developing countries it can be as high as 30%, with 50% for both men and women, and some reports show that the overall quality of male semen in China is declining at a rate of 1% per year. Therefore, abandon the traditional idea that women are responsible for men have nothing to do with the joint participation in pre-conception examinations and health care is a positive condition for the birth of healthy offspring. 2.What do men need to pay attention to before childbirth? How long do I need to avoid smoking and alcohol in advance? A: According to the fifth edition of the WHO Laboratory Test Manual for Human Semen and Sperm-Cervical Mucus Interaction, the lower limit of normal male semen concentration is 1.5×106/ml, which is much lower than the normal lower limit in the previous editions. Men need to pay attention to preconception health care and start with lifestyle habits and details. Maintain a good lifestyle and stay away from chemical pollution, high temperature environment, electromagnetic radiation and radioactivity, as well as long-distance driving. Since the growth cycle of a healthy sperm is about 72 days, we recommend to start staying away from smoking, alcohol and bad habits at least 3 months in advance to avoid affecting the production and maturation of healthy sperm. 3.What are the items of male semen examination? Do I need to check every item? A: Our semen examination items include routine semen examination, pathogenic bacteria (mycoplasma, chlamydia) examination, trace element examination, seminal plasma fructose examination, seminal plasma alpha-glucosidase examination and seminal plasma acid phosphatase examination. The health of the male reproductive system, like other systems (such as the endocrine system, circulatory system, etc.), cannot be determined by one single test. Therefore, a comprehensive evaluation of the health of the reproductive system requires a combination of indicators. 4.Is it hopeless for the male partner to get pregnant if he has a poor semen test result? A: According to the 5th edition of WHO Laboratory Manual of Human Semen and Sperm-Cervical Mucus Interaction, the quality of male semen fluctuates greatly, and one semen test alone cannot measure the male sperm production function. 2-3 tests can help improve the accuracy of the evaluation. And pregnancy or not is the combined result of the joint efforts of physical health and mental health. Therefore, maintaining good lifestyle habits, adjusting positive psychological state and actively cooperating with the physician’s diagnosis and treatment is the right way to have healthy offspring. 5.How long is the treatment course for the male partner in order to improve the quality of semen? A: The male sperm production cycle is about 72 days, so a course of treatment is 3 months. The male partner and our male physician work together to improve the male partner’s sperm production environment and semen quality for 3 months and then compare and consider through 2-3 semen examinations. The WHO recommends at least 2-3 consecutive courses of treatment to better understand the degree of improvement of male spermatogenic function. 6.The wife has abnormal preconception test, but the man’s semen test has just reached normal value, is it necessary for the man to continue the test and treatment? A: According to the EAU (European Association of Urology) infertility guidelines, when the fertility of one male or female partner declines, it can be compensated by the high fertility of the other partner. In other words, the normal male can compensate for the lack of fertility in the female by improving his own fertility. While the woman is undergoing treatment to restore her fertility, the man continues to enhance his fertility so that the probability of pregnancy continues to rise. 7.Is there any “sperm conservation” for men? A: The quality of male semen fluctuates greatly, and it is impossible to predict the effect of long-term abstinence on the quality of male semen. So there is no basis for thinking that semen quality will improve after prolonged abstinence. Yet basically all studies show that men who ejaculate again after 24 hours have elevated sperm motility instead! In short, there is no such thing as sperm raising for men. Please ask all couples to increase the frequency of intercourse when their physical condition allows, so as to increase the probability of pregnancy.
