Patient's question:
I feel that my physical fitness has improved in the past two years, but I often have difficulty getting an erection during sexual activity and cannot maintain it. I want to know what detailed tests are needed for this sexual dysfunction.Doctor's answer:
Blood flow. Some men have insufficient blood flow within the penis, such as fibrosis of the corpus cavernosum, causing slow blood flow and making it difficult for the penis to become erect. Anemia, hypertension, high cholesterol, smoking, or pelvic radiation therapy can also lead to changes in blood flow.Testosterone levels. This is an important male androgen. If testosterone levels are low, sexual arousal may begin slowly. Inflammation of the thyroid or pituitary gland, as well as incomplete testicular development, can also cause testosterone levels to rise.
Reason three, psychological.
