Hello my age is 23yrs old erect penis size is 4 inches im length and with a girth of 4inch due to which it looks very thin and i did some research online and it said that it is smaller than the average size but it is normal. But when i visited a urologist he told me that i might have a micro penis and asked me to do a serum
testosterone, test and i did it and the report said my testosterone level is 401 ng/dL so can you please tell me that if it is normal or not and if i have a micropenis??
