What could cause shorter penis, narrow at the base of shaft during erection?
Patient: Recently when I began having erections, I noticed that my penis is much shorter when fully erect and is also much more narrow at the base of the shaft.  This has never happened before.  I am 40 years old.  It is as if something is holding it back and preventing it from maintaining full size and girth at the base. Doctor: Hi,  Phimosis. Contracted foreskin can give a picture as you say. Share a picture for confirmation. Check for blood sugar and foreskin infection.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. S. R. Raveendran, Sexologist
