I am a 32 year old male with C.F. and am married. I want to know if men with C.F. commonly have any loss of sexual interest or low testosterone levels which could contribute to this? Haven't spoken with anyone about this but need to know. I also haven't found any information on this so if anyone knows I would appreciate any input. I do work full-time and attend school on a part-time basis so I am tired quite often which would be a common factor for many men who may not a decreased sex drive. I know this is a sensitive subject and I do not mean to offend anyone. Thanks.
