Men with diabetes can have children, but they should pay attention to the following points: The first point is that diabetes is hereditary, and men with diabetes may pass it on to the next generation. The second point is that diabetes itself can have certain effects on male function, such as the hardness of the penis erection, lasting time, and even the death of a large number of sperm, causing premature birth in women, infertility, etc. Even in the late stage of diabetes, men can become impotent. The third point is that the damage caused by diabetes to the human body is long-lasting and irreversible, for example, it can cause vascular and neurological lesions, which will have a certain impact on men’s energy, especially after having children, which will affect the quality of family life.
