What causes decreased sexual function in a 45-year-old man?

In general, a decline in sexual function in 45-year-old men may be caused by factors such as aging, unhealthy lifestyle habits, prostatitis, hypertension, and diabetes. Appropriate treatment should be based on specific conditions. Details are as follows:

1. Aging

With increasing age, male physiological functions gradually decline. This includes reduced testicular function, changes in hormone levels, and slowed blood circulation. These physiological changes may lead to decreased libido, erectile difficulties, and other issues that contribute to diminished sexual function. This is a normal phenomenon and usually does not require treatment; it is advised not to worry excessively about it.

2. Unhealthy Lifestyle Habits

Poor lifestyle habits such as chronic sleep deprivation, excessive alcohol consumption, smoking, and lack of physical activity may negatively affect overall health, reduce physical fitness, disrupt the endocrine system, and consequently impair sexual function. It is recommended to adopt healthier habits, maintain regular作息 (daily routines), quit smoking, limit alcohol intake, improve blood circulation, and thereby enhance sexual performance.

3. Prostatitis

This condition is primarily caused by pathogen infection, urinary dysfunction, psychological factors, or abnormal immune responses. Inflammation may affect the nerves and blood vessels of the reproductive system, leading to decreased sexual function. Symptoms often include frequent urination and urgency. Patients may follow medical advice to use medications such as levofloxacin tablets, tamsulosin hydrochloride sustained-release capsules, and Qianlieshutong capsules for treatment.

4. Hypertension

Hypertension is a clinical syndrome characterized by elevated systemic arterial pressure, increased resistance in peripheral small arteries, and varying degrees of increased cardiac output and blood volume. It can cause penile vascular damage and impair sexual function. Patients are advised to take medications such as furosemide tablets and enalapril hydrochlorothiazide dispersible tablets as prescribed.

5. Diabetes

Diabetes is a group of metabolic disorders characterized by chronic hyperglycemia due to multiple causative factors. Typical symptoms include polyuria, polydipsia, polyphagia, and weight loss. The disease can damage nerves responsible for signal conduction, thus leading to impaired sexual function. Patients are advised to take medications such as repaglinide dispersible tablets and glipizide dispersible tablets under medical supervision.

Patients are encouraged to seek timely medical attention when experiencing discomfort to avoid delays in treatment. Additionally, maintaining a light diet and ensuring adequate rest are recommended in daily life.
