Myth 1: Abstinence PK Excessive Sexuality Before having a semen test, doctors often ask there patients to abstain from sex. As a result, many patients begin to abstain from sex for a long time in order to get good sperm. In fact, prolonged abstinence does not improve the quality of sperm, but on the contrary will reduce the quality of sperm. Prolonged abstinence increases the number of sperm, but at the same time leads to the predominance of aging and dead sperm, which also affects the vitality of fresh sperm and makes the test results abnormal. In addition, prolonged abstinence also has the potential to induce prostatitis or vesiculitis. In contrast to abstinence, excessive sexual activity is also undesirable. Since it takes time for the sperm to change from old to new, frequent sexual intercourse can cause many incompletely mature sperm to be ejaculated, which can also affect the test results and fertility. Before semen examination, a reasonable abstinence time is 3~7 days. During the abstinence period, pay attention to rest, do not overexert yourself, forbid taking hot baths, and relax mentally and emotionally. Myth 2: One test confirms the diagnosis Because semen quality is easily disturbed by many factors, its quality is often fluctuating. Therefore, one bad result does not mean that there is a problem with the sperm production function, and at least two or more tests are needed before drawing a conclusion. As a rule, one abnormal test can be repeated one to two weeks apart. When the two results are inconsistent, the doctor will analyze the patient’s situation at the time of the two examinations before making a diagnosis, and a third examination will be required if necessary. Myth 3: Poor sperm vitality will affect embryo quality Clinically, we often encounter patients whose wives have one or more unavoidable miscarriages and will have their husbands run in for a semen check, suspecting that there is something wrong with the sperm. Many people take it for granted that deformed sperm will conceive deformed children, but in fact, this is wrong. The semen examination includes the vitality, quantity and morphology of sperm. These indicators can only determine the level of sperm fertility, and cannot be used to judge the quality of the embryo. The fertilization process of sperm is a process of superiority and inferiority, but many people think of it as a “democratic election”, thinking that if there are more bad sperm, it must be bad sperm that conceive. What is relevant to the quality of the embryo is the kernel of the sperm and egg, i.e. the chromosomes carried by the sperm and egg, and the kernel cannot be determined by semen examination. There is no medical means to clarify the quality of the embryo before the couple becomes pregnant, but only through a series of tests before and during pregnancy to prevent to some extent, and to reduce the occurrence of inevitable miscarriages and birth defects. Regarding sperm morphological analysis, which is very important in semen examination, the general semen routine is to examine live sperm, while morphological analysis is to fix the sperm staining and then to observe and analyze them one by one, for a total of more than 200 sperm. Many patients have sperm whose vitality and number meet the requirements for conception, but if there are problems with the morphology of these sperm, such as vacuolation, acrosome defects, sperm head or tail deformities (pointed sperm with an exceptionally short tail and a folded tail), they are unable to conceive. Finally, the causes of male infertility are complex and commonly include high temperature exposure, varicocele, inflammation of the reproductive system, sexual dysfunction, chromosomal and genetic abnormalities, cryptorchidism, testicular dysplasia, vas deferens obstruction or dysplasia and certain drugs, but a considerable number of patients cannot find a clear cause and may be related to poor lifestyle habits, including staying up late, drinking alcohol, frequent sauna bathing and mental stress. Therefore, male infertility patients should look for the cause from many aspects and try to treat the cause as much as possible.
