Diabetic patients can have a married life. For male patients, in the early stage, if the blood sugar is well controlled, or because of the relatively short course of the disease, there is no diabetic vegetative neuropathy, the penis can be erected normally and complete the normal process of sexual life. Afterwards, due to the prolongation of the disease, if the blood sugar control is poor, gradually the phytonuropathy will be involved to the point of premature ejaculation or even impotence, and this is when the sexual life will really be affected. Therefore, male patients are often advised to keep their blood glucose in the ideal range and strictly meet the standard, so as to delay the emergence of chronic complications of diabetes as much as possible, and to maintain a normal life as much as possible, and to go to school, get employed, get married and have children normally. For women with diabetes, the main impact of poor glycemic control is the development of various vaginal inflammatory diseases that affect the quality of life of the couple.
