Introduction: "Doctor, I have been married for a year and haven't had any contraceptive measures. How come I haven't gotten pregnant yet? Both of us are in good health, and my semen routine tests are normal. Why can't I conceive a child?" "In fact, the semen routine test results cannot reflect your fertility, and we still need to be tested..."
Can a normal sperm test result guarantee pregnancy?
Many couples with normal examination results will have the same question: Why do men still have infertility when sperm motility is normal?
Many people think the result of male sperm motility is too absolute, and think that male infertility is due to insufficient sperm motility. In fact, this is a cognitive misunderstanding of routine semen examination.
Hospital experts explained that sperm vitality is an inspection indicator, which only represents sperm activity. That is to say, if sperm motility is good, the probability of pregnancy will be higher. If sperm motility is poor, the probability of pregnancy will be lower, but it does not represent that sperm has absolute fertility and egg penetration ability.
To address the issue of male infertility, analysis and rational judgment should be conducted from multiple perspectives, rather than relying solely on routine sperm tests to determine.
"We should have a rational judgment on the routine examination indicators of male semen. The sperm motility is one of the important factors for pregnancy, but we also need to check the ability of male sperm to penetrate eggs, DNA integrity, etc." The experts emphasized.
Hospital experts remind the majority of male friends that if sperm motility is found to be low, a pile of drugs will find out the cause as soon as possible and carry out targeted treatment.
Normal sperm but infertility, you also need to check sperm function
The routine examination of male semen covers multiple items, mainly including three aspects: checking the number of sperm, sperm motility, sperm deformity rate, and integrity. Routine semen examination indicates the presence of diseases in males, but does not reflect their true fertility.
Many men's sperm routine tests have met the standards, and if they are still infertile, advanced semen tests are required.
For example, if there is a significant abnormality rate in semen, it is necessary to test the male DNA fragment index (DFI) of sperm, which helps to further understand the integrity of sperm DNA and chromosomes. The indicators of this examination are of great significance. If the male DFI value is relatively high, it indicates that the sperm DNA and chromosomes are incomplete, which can cause obstacles to the fertilization process and affect embryo conception.
Seminal biochemical testing, which is a more advanced semen examination than DFI, can understand the entire process of semen production, and infer which accessory gonads have problems through abnormal results, directly identifying the problem.
In addition to DFI and seminal plasma biochemical testing, there are also more in-depth and high-level sperm functional tests, including hyperthyroidism antibodies, sperm agglutination tests, sperm penetration tests, etc. Due to the high requirements for testing personnel, equipment, and technology, not all medical units can complete this series of tests well.
Additionally, not everyone needs to undergo a sperm functional test, as routine semen tests can already provide most of the information about sperm. Sperm functional tests are only targeted at individuals with special abnormalities in sperm routine results.
