Impotence is either a physical problem or a sub-conscious problem. If it's a physical problem you need a doctor, if it's a sub-conscious problem you need a hypnotist.
It's easy to tell if the impotence is sub-conscious. If you get an erection while you are sleeping it's probably a sub-conscious problem.
If you get an erection with one lover and not another it's probably a sub-conscious problem.
If you get an erection before penetration and then lose it, it's probably a sub-conscious problem.
If you are able to get an erection while masturbating it's probably a sub-conscious problem.
If it is a sub-conscious problem it's easy to reprogram the sub-conscious mind to maintain an erection during intercourse while in hypnosis.
According to the British Journal of Urology, hypnosis improved the sexual function of men with no organic cause for their impotence at a rate of 80%. The interesting part about this study is that hypnosis outperformed both testosterone and trazodone. [Aydin S et al. "Efficacy of testosterone, trazodone and hypnotic suggestion in the treatment of non-organic male sexual dysfunction." British Journal of Urology. 77(2):256-60, 1996.] According to the Scandinavian Journal of Urology and Nephrology , erectile dysfunction that cannot be linked to physical causes has been successfully treated by hypnosis. Three out of every four men in the trial were helped. [Scandinavian Journal of Urology and Nephrology . 31: 271-4, 1997]
