Patients with diabetes can have intercourse as long as their condition is well controlled. This is because the metabolic disorder of blood sugar in diabetic patients may affect the secretion of sex hormones. For men, it will cause a decrease in androgen secretion, and for women, it may cause a decrease in estrogen secretion, which will affect the patient’s sexual function and thus affect the life of intercourse. However, as long as the disease is well controlled, the androgen secretion in men and the estrogen secretion in women will be relatively less affected. From the pathological point of view, the cause of the patient’s sexual dysfunction can be improved to the greatest extent. In this case, as long as the patient excludes other factors, such as psychological factors, etc., intercourse is certainly no problem. Therefore, it is very important for diabetic patients to control their condition in a reasonable and standardized way.
