1.What is oligospermia? Oligospermia is divided into two types: oligospermia and oligospermia evidence. The kind of thing you are talking about has reduced density. It does not mean that the total number is reduced. It depends on two indicators. One is the total volume of semen. The other is the sperm density. 2, as long as less sperm will affect fertility? Strictly speaking, yes. Theoretically, conception is possible if there is one active sperm. But conception is a very complicated immune escape process. So it takes a lot of sperm to do the job of plugging the robbing eyes. That’s why in only have the total amount of semen you can see in 2-7 ml. The sperm density is greater than 20 million per ml. 3.Does oligospermia affect the quality of the fetus? It may affect. The semen quality is not satisfactory. You cannot exclude that it affects the spatial architecture of the chromosomes in the head of the sperm. This determines the synthesis of proteins. 4.What is oligospermia? A sperm motility of less than 60% is diagnosed. Usually three indicators are referred to at the same time. The other two indicators are a-grade sperm and b and sperm content. 5.Does weak sperm affect fertility? As long as the weak sperm will affect fertility. The most direct effect is that it is not possible to conceive a child for a long time, with less than 25% of a-class or less than 50% of a+b. 6.Does weak sperm affect the quality of the fetus? What is the sperm development status of patients with weak spermatozoa. There are no organelle defects are not to say. The probability of morbidity is higher. That is to say, it may affect the quality of the fetus. 7.Is there a high incidence of oligospermia and weak sperm? The incidence of weak spermatozoa is high. The incidence of oligospermia is low. It can occur at the same time. Weak spermatozoa can account for 70% of outpatient records and oligospermatozoa less than 10%. 8.Does oligozoospermia run in families? From the point of view of biological evolution, patients with slightly weak sperm have a low ability to reproduce the species themselves. If in the animal world, it is the individual of the species that is eliminated. In humans if it is caused by acquired factors is curable this part will not be inherited. If it is a congenital factor, it is possible to inherit it.
