Have Urology Questions? Ask a Urologist Online.
Hi and thanks for the reply.
Not having a morning erection or nocturnal penile tumescence means that there is something affecting either the nerve supply or the vascular (blood) supply of the penis. I would suggest that you visit a Urologist at the earliest and have this examined. A few tests are also warranted which include x rays of the lower lumbosacral spine, nerve conduction studies, artificial erection test etc.
Let me know if you need to know anything more.
