I've had ED since my early 40's. Every remedy they tried worked for a few months and then stopped working. These included yohimbine, testosterone injections, Viagra (never worked at all), and direct penile injections. The last worked really great for about a year but even that stopped working. I gave up about 10 years ago. I still have a strong libido and can ejaculate several times a week, just no erections. Has anything new been developed since then?
