What determines hardness?

Male erection hardness is mainly determined by five factors: vascular function, hormone levels, neural regulation, psychological state and lifestyle.

1. Blood vessel function:

The degree of congestion in the corpus cavernosum directly affects erection hardness. When arterial blood supply is sufficient and venous return is blocked, pressure within the cavernous body increases, forming a hard erection. Diseases such as endothelial dysfunction and atherosclerosis can lead to insufficient blood supply and are common in patients with hypertension and diabetes. Improving vascular function requires controlling underlying diseases, and using phosphodiesterase 5 inhibitors if necessary.

2. Hormone levels:

Testosterone is a key hormone for maintaining sexual function, and low levels can reduce erection hardness and libido. After the age of 35, men's testosterone decreases by 1%-2% every year, and obese people are more likely to suffer from hormone imbalance. When accompanied by symptoms such as decreased morning erections and loss of body hair, it is recommended to detect free testosterone. Hormone replacement therapy requires strict assessment of prostate risk, and regular strength training can naturally increase testosterone secretion.

3. Neuromodulation:

Intact nerve conduction pathways are necessary for erection. Spinal cord injuries, central neuropathies such as multiple sclerosis, or diabetic peripheral neuropathy can all affect signal transmission. Neurogenic erectile dysfunction often presents with a sudden loss of hardness, which may be accompanied by perineal numbness. Nutrients combined with pelvic floor muscle training can help improve nerve sensitivity.

4. Mental state:

Emotional problems such as anxiety and depression inhibit erections through sympathetic overexcitation. It is characterized by situational lack of hardness, which is normal during masturbation but decreases during sexual intercourse. Cognitive behavioral therapy can alleviate performance anxiety, and participating in therapy with a partner can reduce psychological stress. Be wary of dependence when using anti-anxiety drugs for short periods of time.

5. Lifestyle:

Smoking damages blood vessel endothelium, and nicotine constricts blood vessels by more than 30%； Alcoholism inhibits central nervous system excitability ； Sitting for long periods of time causes the pelvic floor muscles to atrophy. Improvement suggestions include 150 minutes of aerobic exercise per week, squats and Kegel exercises to strengthen pelvic floor muscles, and a Mediterranean diet to supplement arginine. Lack of sleep will reduce testosterone levels, so it is especially important to ensure 7 hours of deep sleep.

Maintaining good erection hardness requires comprehensive management. It is recommended that men over 40 years old have their blood pressure, blood sugar, blood lipids and hormone levels checked every year. You can eat more zinc-rich seafood and pumpkin seeds on a daily basis, and supplement vitamin D to promote testosterone synthesis and avoid high-temperature environments from affecting testicular function. If the hardness continues to decrease for more than 3 months, you should seek medical advice as soon as possible to rule out potential risks such as cardiovascular disease. Intimate communication and moderate sexual stimulation between partners can also effectively improve erection quality.
