New medication shows promising results for men with low testosterone

(WPLG) If you're a man having trouble losing weight, feeling tired or maybe your love life isn't what it used to be, you may be experiencing low testosterone levels. South Florida doctors are studying a new treatment that may help without the usual side effects.

Among the men affected by low testosterone levels is Tomas Kenny, 27, who learned he has a deficiency after experiencing some of the telltale symptoms.

"The most notable one for me was a lowered libido," he said. "For a man in my mid-20s, it didn't make sense. And then there was fatigue. Those were the two symptoms for me."

Since Kenny is a young man and newly married, traditional testosterone replacement therapy isn't recommended.   

Doctors said there are two major side effects.

"One, it blocks the sperm production, especially for young men or men who wish to conceive in the future and are still interested in fertility and family building," said Dr.Ranjith Ramasamy, director of reproductive urology at the University of Miami Health System.

Ramasamy said testosterone therapy also blocks any natural testosterone production.

Those were deal breakers for Kenny.

"As a young married man, you want to keep your options open (and) don't want to close off any avenues with your wife and our ability to have kids or not," he said. 

But doctors are now studying a medication called Natesto, a nasal testosterone gel that does not appear to have the negative side effects.

Kenny uses it three times a day.

The University of Miami Health System is the only location in the country studying Natesto. So far, 12 men have participated in the study and doctors say all of them have had promising results.

"We have so far found all the men on the nasal gel therapy for at least three months, they are very happy, testosterone levels have improved and their sperm production is maintained," Ramasamy said.

Kenny said he felt a difference almost right away.

"What it comes down to is, are you happy with your quality of life? And for me, there's been a marked improvement," he said.
