Abortion refers to interruption of pregnancy at less than 28 weeks of pregnancy.The main cause of miscarriage is the abnormalities of pregnancy eggs and embryos, followed by the maternal lesions (disorders of endocrine function, and maternal sufferings of systemic diseases, etc.) and external factors (abdominal surgery or external injuries).In the early abortion, 80 % of the embryo development was abnormal.Abnormal embryonic development can be caused by defects of eggs or sperm or both. Most of them eventually abortion or dead tire due to developmental disorders.Traditionally, people believe that habitual abortion is caused by the woman, such as endometrial endometrial dysplasia, incomplete cervical endogenic function, and inconsistent blood types of mother and child.But this kind of understanding is incomplete. Modern medicine believes that habitual abortion, especially the habitual abortion of perbal perfection, is often related to men, which mainly includes the following factors:
Chromosome
Because the sperm with abnormal chromosomes is too poor, it is usually difficult to fertilize the eggs. If the eggs are fortunate to be fertilized, the result must end in abortion.
Immune factors
After the woman is pregnant, the embryo is also a foreign body for the mother, and she will certainly be immune to the mother.However, there is a blocking antibody in the mother's body, so it can protect the fetus and avoid exclusion.When the cellular types between couples are closer, their antigens are insufficient, causing the mothers to lack necessary blocking antibodies and increase the possibility of abortion.
Sperm
Sperm with poor quality makes it difficult for the woman to conceive, but it does not exclude the possibility of making the woman conceive. If the woman occasionally conceives, a habitual abortion will generally occur.
In addition to the above factors, there are other factors that cause habitual abortion.For example, sexual life during pregnancy can cause mechanical stimuli to the pregnant uterus, and the prostaglandin in the semen can shrink the uterus; some harmful factors in the man's work and living environment damage the distortion of reproductive cells and induced chromosomes.Factors may cause habitual abortion.
Therefore, both men and women have many factors that cause habitual abortion.If habitual abortion occurs, you should go to the obstetrics and gynecology hospital for examination in time, clarify the cause, and treat symptomatic treatment.
