Urologists are highly trained specialists that diagnose and treat disorders of the genitourinary system, which includes the kidneys, bladder, adrenal glands, urethra and reproductive organs. Many people know that urologists treat prostrate issues in men, but they may not know that a urologist can also help with both male and female infertility. In some cases, a woman may also need to see a urogynecologist (for conditions affecting the bladder and female fertility such as a pelvic organ prolapse), although a urologist is qualified to render care for both sexes.
