CHICAGO While most frequently associated with women's health, age-related hormone changes, often dubbed menopause, can occur in men as well, causing symptoms of fatigue, mood swings, decreased desire for sex, hair loss, lack of concentration and weight gain. Experts estimate that more than 5 million men are affected, yet worry the number may be considerably higher since symptoms are frequently ignored.
Male hypogonadism, as it's referred to in the medical community, occurs when the testicles do not produce enough testosterone, the hormone that plays a key role in masculine growth and development. When hormone levels drop, men can experience significant mental and physical changes.
"This is a highly prevalent disorder," said Robert Brannigan, MD, urologist at Northwestern Memorial Hospital. "Unfortunately, we estimate that 95 percent of cases are undiagnosed and therefore untreated. When ignored, symptoms can seriously disrupt one's quality of life."
"My body was telling me that something wasn't right. I was always tired, it didn't matter how much sleep I got, I constantly wanted to take a nap," said Michael Andruzzi, a 40 year old man diagnosed with male hypogonadism and a patient at Northwestern Memorial.
Brannigan explains hormone variations are a normal aspect of getting older. "In females, ovulation comes to an end and hormone production declines in a relatively quick period of time, whereas men experience hormone shifts more slowly, with testosterone levels dropping around one percent each year beginning in a man's late thirties," adds Brannigan, who is also an associate professor of urology at the Northwestern University Feinberg School of Medicine.
Brannigan goes on to explain that by age seventy, the reduction in a male's testosterone level could be as high as fifty percent or more compared to baseline levels, but notes that aging men are not the only ones at risk. A number of genetic causes can
