Patients with diabetes can have children if they are male, but they should not have children just because type 2 diabetes is a genetic disease. Although type 2 diabetes has a genetic component, by medical definition, type 2 diabetes is not a hereditary disease, which means that the probability of type 2 diabetes being inherited is relatively low. The reason there is a genetic component is that people with type 2 diabetes often have many susceptibility genes for diabetes, and although there is a genetic possibility, it also has to be combined with other risk factors to trigger the onset of diabetes. It is perfectly possible to have children with diabetes, and you can rest assured that the condition must be well controlled in order to maximize the impact on the reproductive system and to ensure that the activity of the sperm is ideal, in order to facilitate the entire process of pregnancy and the fertilization of the egg, which is also very crucial for the subsequent health of the child.
