There are many reasons for male genitals not to be able to have an effective erection. The common ones are insufficient androgen level, deficiency of kidney qi, chronic prostatitis or lesions of the penile corpus cavernosum, which need to be clearly diagnosed through further examination, including blood test for androgen level, routine prostate fluid, ultrasound examination of the prostate and penile blood flow Doppler examination. If the test is found to be caused by insufficient androgen level, you can take oral testosterone undecanoate capsule, Jin Kui Kidney Qi Pill and Wu Zi Yan Zong Pill for 2-3 weeks to improve the symptoms. If the examination reveals that it is chronic prostatitis, you need to choose anti-inflammatory Chinese medicine, such as Prostate Antong Tablet, Retention of urine Tablet, Sanjin Tablet, for 4-8 weeks of symptomatic treatment, which can effectively improve the erectile function. If the symptoms are caused by penile cavernous body filling dysfunction, you can choose Rhodiola capsules and Thromboplasma tablets for 1-2 months of treatment, and the erectile function of the penis can also be effectively improved.
