unusual penile shrinkage(70+)
  I am aware that some penile shrinkage in older males is normal, however, my case is somewhat odd. My width has remained constant but my length has decreased by 48% within the last two years.  I am 73, use free weights/exercise equipment and walk a mile daily. I have no health problems, visit my physician tri-annually and to date have had no erectile/ejaculatory problems.  Sixteen years ago I did have quadruple bypass surgery, yet encountered no problems.  Three months ago I was treated for a minor UTI.  I now find that I am unable to ejaculate due to lack of penile stimulation since I cannot penetrate beyond the vaginal opening. I also become flacid for a period of about 5 minutes, recover my erection, only to become flacid again before returning to normal. Could I possible be experiencing a drop in harmone levels due to advancing years or could it indicate some other medical dysfunction?

Dear David,
Thanks for your question. Penile shrinkage is well known to occur in cold weather. This is due to excessive contraction of the sinusoids within the penile tissue as these respond to sympathetic overstimulation. However penile shrinkage as you describe is not  a  common problem. Indeed in old age one loses the tissue strength all over the body and penile tissue is no exception. People with increased fatty tissue in the lower abdomen (suprapubic area) may have the penis partially covered by fat giving the appearance that the penis is shorter.  The symptoms you describe such as flaccidity soon after erection are the symptoms of erectile dysfunction. The penile tissue loses it ability to store blood during erection as one gets older. I  can not explain the lack of penile sensation. Hormone levels do go down as one gets older and this may contribute to the problem. You should see a Urologist. There are several new medications and devices that could take care of your problem.
