Genetic diseases are indeed frightening. However, if prevention is done early, their harm can be relatively reduced. Genetic diseases begin to develop during the embryonic stage and even when the sperm and egg combine. When choosing a partner or planning for childbirth, it is important to consider how to prevent genetic diseases, which is also an important aspect of implementing eugenics.
1. Avoid falling in love with someone who has the same genetic disease and prevent the marriage between two individuals with the same genetic disease.
If individuals with the same genetic disease marry each other, the chances of their children having the same genetic disease as their parents will significantly increase. Examples of such diseases include primary hypertension, atherosclerosis, diabetes, congenital heart disease, myasthenia gravis, spina bifida, cleft lip, congenital hip dislocation, congenital asthma, congenital deafness and dumbness, and high myopia.
2. Avoid consanguineous marriages, as the incidence of recessive genetic diseases in the offspring of consanguineous marriages is significantly higher than that in the general population.
Research has shown that the likelihood of offspring having genetic diseases increases when they are born to parents with various severe diseases. Patients with viral hepatitis, tuberculosis, sexually transmitted diseases, and other serious organic diseases should also not rush into marriage.
3. Choose the right time for conception. The age of both spouses should be appropriate.
If the woman is over 35 years old, the chances of the offspring having congenital mental retardation can increase by about 10 times. The man's age should preferably not exceed 50 years old.
4. Pay attention to the "external environment" that both the man and woman are in during conception.
For example, if they are currently in close contact with toxic substances (such as undergoing radiation therapy or spraying pesticides), or if they are using drugs that can cause harm to the embryo, they should not immediately conceive. Pregnancy should only be considered after avoiding harmful external environments for a period of time.
5. Mothers who have had two or more consecutive natural miscarriages.
Chromosome tests should be conducted to determine if they are related to genetic factors. The decision of whether to conceive again should be made by a doctor.
6. Mothers who have had a malformed fetus in the previous pregnancy.
Before attempting to conceive again, a comprehensive examination by a doctor should be done to determine the cause of the malformed fetus and then decide whether to proceed with pregnancy.
