First of all, the analysis of the main indicators of semen routine analysis, such as density, vitality and morphology, must be combined with medical history. Without a medical history, it is extremely naive and irresponsible attitude towards the patient’s treatment to simply analyze the laboratory test. This is because: firstly, semen routine is not a functional experiment, it is a rough judgment of fertility only by the density, vitality and morphology of sperm, which is like judging people by their appearance, it is not very accurate; great men like Napoleon and Deng Xiaoping were short, you cannot say they were less capable, members of the State Guard were handsome and dashing, you cannot say they were super capable on this basis; secondly, semen routine analysis cannot determine the fertilization of the few sperm that reach the The second is that routine semen analysis cannot determine the fertilization ability of the few sperm that reach the position of fertilization, so to properly assess male fertility requires a comprehensive judgment combined with clinical information such as medical history. The World Health Organization defines male infertility as the absence of fertility for one year due to the male partner’s factors, when both men and women are not using contraception and have a normal sexual life. In our clinical work, if the woman is ≤ 34 years old, the limit is 1 year; if the woman is ≥ 35 years old, the treatment process of infertility can be entered in half a year. If there is a history of infertility: Regarding the issue of sperm morphology, the WHO laboratory manual (4th edition) does not have normal reference values, except for a note after the normal reference values of other semen parameters: the success rate is lower when doing in vitro fertilization-embryo transfer (IVF-ET) when the normal sperm morphology rate is <15%. the WHO laboratory manual is the gold standard for evaluating male fertility, and if this standard is followed The WHO Laboratory Manual is the gold standard for evaluating male fertility, and if this standard is followed, then sperm morphology is only relevant to the success rate for IVF-ET and has no clear impact on other aspects at least. The WHO Laboratory Manual (5th edition) may consider a normal morphology of 4% or more to be sufficient. Sperm morphology can fluctuate, but there are no authoritative experimental data, so it is not expected to fluctuate much. There is no special medicine for morphological abnormalities, I think you can simply use some vitamin E, five son derivatives and other simple drugs.
