Andrologist is the medical practitioner who deals with diagnosis and treatment of diseases related to the male reproductive and urology organs such as fertility and sexual problems. Andrologist is trained to treat disorders like erectile disfunction, infertility, and genital trauma of their patients generally ranging from puberty to the elderly age. They use a variety of treatments such as medication, hormone therapy or even surgery for the treatment of the patients.Increasing cases of male infertility and other related disorders have increased the demand for a specialized medical professional in the recent past.Medical treatment of male infertility remains a problem with a difficult solution and is terribly unsatisfying for andrologists. Although there have been some notable successes with the new techniques in assisted reproduction, getting pregnancies with poor quality semen samples and the lack of medical etiologic treatment do not manifest more than the ignorance of much of the mechanisms that cause infertility.
