###Human: I am unable to maintain erection even after GAINSWave treatment. Why? ###Assistant: Hello. Your lipid values and blood sugar values are absolutely normal (attachment removed to protect patient identity). I would like to say a few points here. Lisinopril HCTZ (Hydrochlorothiazide) is a combo of two drugs in which HCTZ has erectile dysfunction as one of its side effects. Hydrochlorothiazide need to be replaced with a different drug or removed. You are on three antihypertensives Lisinopril, HCTZ, and Amlodipine. Is your hypertension that severe? Testosterone implant may improve your libido but may not benefit ED (erectile dysfunction) always unless there is a gross hormonal dysfunction. SSRI group of medicines are prescribed to delay ejaculation. I do not know why were you prescribed one. That is the culprit which has stopped your ejaculation totally. Better to discontinue it. Instead of Sildenafil for erection, you can try tablet Tadalafil 10 mg (Cialis) after consulting your andrologist. The erectile effects of Sildenafil are short lasting whereas Tadalafil has prolonged effects and one pill on Friday will make you have a wholesome weekend. It may even stop the need to have intracavernosal injections. One investigation which I would suggest you is a penile doppler which gives an idea of blood flow to the penis. GAINSWave is an addon to cure you fast. Penile doppler study. ED.
