If both husband and wife have their own children after divorce, it means that they have no problems in fertility. But why can't they get pregnant together? Because of the existence of anti-sperm antibodies, male semen is the antigen of women.
Hereditary blood group problem
In addition to infertility caused by anti-sperm antibodies, some couples can't get pregnant because their genes and blood types don't match. Even if it is combined into a "fertilized egg", it will "not survive" for various reasons. However, after the divorce, they remarried and changed partners. Maybe the other half doesn't have the above problems, and then naturally, they can have another child after they get together.
psychological cause
Psychological reasons are also the key factors that affect couples who have no fertility problems from getting pregnant. Many couples are under too much pressure when they are together. When the pressure is beyond their tolerance, it is naturally difficult to get pregnant. And because it takes a long time to get pregnant, you can't get pregnant, which may be more stressful.
Big, and then the other way around. On the contrary, after the divorce, both of them may have opened their eyes and soon became pregnant, instead of insisting.
There are still some couples who can't get pregnant, and they have no problems themselves. But if these problems are not solved, it will be difficult to get pregnant, because one party has serious psychological obstacles, such as sexual fear, or the object of marriage is not what he likes, but he has to get married under some pressure, and so on. Only by excluding all external factors that may affect pregnancy can a good pregnancy come as soon as possible.
