Hello Dr.
I'm a 36 year old male. In 2001 I had a bout with Peyronie's that left me functional, but with a little distal rigidity issue (the glans doesn't fill up and get hard like it used to). I was prescribed Viagra, as this makes my erections very hard and prevents the lack of firmness at the head from interfering with maintaining the erection.
However, for the last 5 years or so, I've noticed that my nocturnal erections have disappeared, as well as no morning erections and no spontaneous erections. This got me thinking maybe my testosterone was low, so I had it tested.
The results were as follows: Total T 235; Percent Free 1.71; Free T 40.2; FSH 5.1; LH 3.4; Prolactin 6.1.
Based on the low total number (235), I've scheduled an appt with an Endocrinologist, but I'd like to ask you if you think these numbers seem to indicate that testosterone could well be the cause for my lack of nocturnal/morning/spontaneous erections. I'm hoping that testosterone replacement might even make me not need Viagra at all.
One last related question: though I always take Viagra on an empty stomach, some times Viagra has worked on me less effectively than others - for instance, usually, an hour after I take it, if my girlfriend and I just start kissing, etc., I'll get erect, but on some occasions, it would require direct stimulation for a few minutes to get erect. Once I was "up" it was clearly a Viagra erection though - very hard and durable. This would scare me though that the Viagra was losing it's effectiveness on me, but in light of my low testosterone, might it not be that the Viagra is keying off fluctuations in my hormone levels - sometimes really kicking in hard, while other times not working as fast?
As I said, I'm going to see an Endo, but I'd like to hear if you'd support this course, based on the test results.
Thanks for your counsel, I appreciate your thoughts.
