[|Human|] I have small non itchy non painful scabs on the back of the head of my penis . I have two children and during the first pregnancy my wife was treated for chlamydia . So was I. During the second pregnancy, she had no STDs. My wife has been my only sexual partner for the las 13 yrs. if she has no STDs then neither should I. What could these scabs be?
[|AI|]  Hello, Thanks for the consult: 1. Small non-itchy non-painful scabs on the back of the head of your penis is look like of having Sexually transmitted disease (STD) and the likely disease is syphilis caused by Treponema pallidum 2. Chlamydia causes painful or tender scabs, so it can be ruled out 3. Tests you should be done like Polymerase chain reaction test (PCR) to check for microorganism and other serological tests 4. Penicillin Injection is the treatment of choice if test is positives information helps
