Patient's question:
What is the reason why my husband suddenly lost his erection and what should I do?Doctor's answer:
There are many reasons for premature ejaculation. For example, vascular causes include any condition that may lead to increased blood flow to the penile corpus cavernosum, such as atherosclerosis, arterial injury, arterial stenosis, pudendal artery shunting, and cardiac dysfunction. It can also be caused by damage to the penile tunica albuginea, which affects venous inflow and the closing mechanism, or by increased smooth muscle in the penile cavernous sinus, leading to penile venous leakage. Endocrine diseases can also cause impotence, primarily seen in diabetes, hypothalamic-pituitary abnormalities, and primary gonadal dysfunction.
