Indications for Circumcision and Warning Signs of Diabetes in Men's Health

Who Needs Circumcision?

The foreskin is a thin layer of skin covering the glans penis. In infancy, the foreskin usually completely covers the glans. However, as the penis grows, the accumulation of smegma under the foreskin gradually separates it from the glans. Intermittent erections allow the foreskin to retract naturally. However, in some adult men, the glans and urethral opening can only be exposed when the penis is fully erect or when the foreskin is manually retracted; this is called phimosis. Others have a foreskin opening that is too small or too tight, preventing retraction or exposure of the glans and urethral opening even during erection; this is called paraphimosis. Both of these conditions require circumcision because they have many risks.

Smegma accumulates under the foreskin in men. In cases of phimosis and paraphimosis, smegma cannot be cleaned promptly, creating a chronically unclean environment that easily leads to balanitis or posthitis. Over time, it can even cause foreskin stones. Most seriously, long-term irritation of the glans penis by smegma increases the incidence of penile cancer in men. On the other hand, phimosis (tight foreskin) prevents the glans penis from frequent contact with the outside world, leading to increased sensitivity and a higher risk of premature ejaculation. Paraphimosis can potentially cause infertility.

Phimosis and paraphimosis not only affect men but also women. Smegma can increase the incidence of urinary tract infections in women and, through long-term chronic irritation, increase the incidence of cervical cancer.

Therefore, phimosis and paraphimosis pose significant risks to both men and women. Men with phimosis may not require surgery if it does not interfere with normal sexual life and they maintain good hygiene. However, men with paraphimosis must undergo circumcision as early as possible to prevent problems for themselves and their partners.

Why are diabetic patients prone to erectile dysfunction?

Diabetes can cause erectile dysfunction. According to foreign medical statistics, the incidence of erectile dysfunction in diabetic patients aged 25-55 is as high as 30%-60%.

Erectile dysfunction is a complication of diabetes, and its causes are complex, mainly due to a combination of factors including neurovascular disease and impaired glucose metabolism. Because diabetes is a disease involving the function and metabolism of multiple organs and tissues, high blood sugar levels primarily affect the function of the hypothalamus, pituitary gland, and testes, causing hormonal imbalances and making it difficult to achieve an erection. If diabetic patients experience abnormal lipid metabolism, lipids and polysaccharides adhere to the inner walls of blood vessels. When the blood vessels supplying the penis become obstructed, the corpora cavernosa of the penis do not receive sufficient blood supply, which is also a significant factor contributing to erectile dysfunction.

Most patients experience sexual dysfunction simultaneously with other diabetic symptoms. However, some patients show a lack of interest in sex or even develop erectile dysfunction before the onset of diabetic symptoms.

Therefore, experts point out that middle-aged men who experience difficulty achieving or maintaining an erection or lack of interest in sex should ideally undergo a health check-up and have their blood sugar levels tested. If elevated blood sugar is detected and diabetes is diagnosed, comprehensive prevention and treatment measures must be implemented under the guidance of a doctor, addressing the underlying causes as early as possible. Clinicians believe that if patients with early-stage diabetic erectile dysfunction adhere to a scientifically planned diet, limit total calorie intake, minimize consumption of fatty and rich foods, and use medication as prescribed to stabilize blood sugar at a near-normal level, while avoiding adverse stimuli and maintaining a positive mental state, the progression of the disease can be effectively controlled, and sexual dysfunction may be completely or partially alleviated or even recovered.
