Obesity has some effect on sexual function.
For obese men, the level of free testosterone (that is, the part of testosterone that is physiologically active) is lower in the severely obese than in normal people, and it is much less elevated during arousal tests than in the average person. On the other hand, estrogen is produced in adipose tissue, and the more adipose tissue there is, the more estrogen is synthesized. Therefore, the estrogen level in obese men is higher than that of normal men, and a few can even develop feminine manifestations such as impotence and breast development as a result. So in general, obese men are likely to have reduced libido and sexual function.
The situation of obese women is different from that of men. Since hyperinsulinemia can stimulate the ovaries to produce excessive androgens, the level of free testosterone in the body may be higher than that of ordinary women, resulting in masculine manifestations such as hirsutism in women, and may also cause menstrual disorders or even amenorrhea and sterility. In addition, obese women are often easy to combine with acanthosis nigricans, manifested as the neck, underarms and thighs root skin and dark and thick. Obese women’s skin is also easy to grow ringworm, boils, plus masculine performance, very affect the appearance of women, sex life caused by adverse psychological impact.
Obesity also has restrictions on the choice of sexual position, which is not conducive to the quality of sexual life.
Obese people are prone to diabetes, and men with diabetes can develop impotence secondary to this, and women can develop sexual frigidity and vaginitis as a result, which may further affect sexual function.
