What tests should men take before pregnancy?

In recent years, with the improvement of people's understanding of reproductive health, more and more young couples have begun to pay attention to pre-pregnancy checkups, and couples of childbearing age hope to have a healthy baby. Don't think that pre-pregnancy checkups are the exclusive right of women, men also need to check. According to relevant statistics, half of infertility is caused by male factors. Nowadays, there are more and more male infertility patients. Most people focus on women, but ignore the male factors. Let's talk about what pre-pregnancy checkups men should do.

1. Routine semen examination As we all know, the fusion of sperm and egg can produce a baby. The number and quality of male sperm affect the probability of pregnancy. According to scientific research reports from all over the world, the number of sperm in men worldwide has decreased by 20% to 30% in the past half century. This may be related to endocrine imbalance caused by air pollution and the increased pressure of life of modern people. The purpose of routine semen examination is mainly to measure the number and quality of male sperm, which can basically evaluate the male's reproductive function, which is very important for infertile couples. Compared with the examination of female reproductive function, the routine semen examination of men is more convenient and simple. Common problems in routine semen examination: Incorrect semen collection methods will have some impact on the results and cause misdiagnosis. In order to make the test results more accurate, the following matters should be noted: 1. There should be no ejaculation (including no ejaculation in sexual life, no leucorrhoea, and no frequent ejaculation) for 2-7 days before semen collection; 2. It is best to collect semen in the morning; 3. After semen collection, it should be placed in a 37℃ water bath for insulation and heat preservation, preferably in the room 1. The sperm collection room, which is close to the testing laboratory, is self-service, as long-term exposure of semen to indoor temperature will affect sperm activity; 2. Prevent semen loss during the entire process of semen collection, especially the small part at the beginning, which is the part with the largest number of sperm; 3. If condoms are used to collect sperm, special condoms without spermicide should be used for sperm collection; 4. No fever, frequent staying up late, alcoholism, etc. in the week before the inspection.

2. Urinary system examination: Routine physical examination or B-ultrasound examination by a male specialist can help understand the male testicles, epididymal cysts, spermatic veins, and male prostate conditions, and eliminate potential sexually transmitted diseases such as small testicles and varicose veins.

3. Other laboratory tests: Blood type test: Incompatible blood types of parents can cause neonatal hemolytic disease, which can be divided into ABO blood type incompatibility and Rh blood type incompatibility. In China, the most common is ABO blood type incompatibility. The incidence of ABO blood type incompatibility hemolytic disease in the first child exceeds 20%. When the mother's blood type is O type and the father's blood type is non-O type, such as A type, B type or AB type, the child is very likely to develop hemolytic disease. Other tests that can be selected: routine blood tests, liver function tests, kidney function tests, infectious diseases (hepatitis B, syphilis, condyloma acuminatum, AIDS, etc.) tests.
