“He said he would rather have sex than have his hearing.”
Could Viagra cause hearing loss?
The late Hugh Hefner thought so according to three of the women in his life. His widow Chrystal Harris told Howard Stern back in 2011 that, “He tries not to take Viagra any more because it makes him lose his hearing.”
In another interview that same year Hefner’s former twin lovers Karissa and Kristina Shannon made a similar claim.
Karissa told The Sun “He said he would rather have sex than have his hearing. He has hearing aids now and even then he can only hear out of one ear.”
“You have to lean down and talk into his good ear for him to understand you. We could sit right next to him and he wouldn’t have a clue what we said.”
Was Viagra to Blame?
There is some tenuous evidence that the class of drugs known as PDE-5 inhibitors such as Viagra, Cialis and Levitra may induce sensorineural hearing loss. A 2007 study found that a few men reported suffering from sudden sensorineural hearing loss (SSHL) after taking PDE-5 inhibitors.
It’s important to note that there has been no proven causal link, and that SSHL is extremely rare. But it was enough for the FDA to require that a warning be included on the labels of PDE-5 inhibitors.
As for Hefner’s hearing loss, well, he was in his nineties after all.
The Drugs You Should Worry About
There are roughly 200 drugs that have been shown to cause hearing loss, including some that may already be in your medicine cabinet.
They are known as ototoxics, oto meaning ear and toxic, of course, means poison. They can result in temporary or permanent damage. If you are already suffering from hearing loss you should be aware that these drugs may cause you to lose more.
Hearing aids help, and I couldn’t function without them. But for those of us afflicted by sensorineural (age related) hearing loss there is now the tantalizing possibility of a cure on the horizon.
Researchers around the world are working on it. I’ve talked with several, and the main focus of their attention are the hair cells and their supporting cells which line the cochlea.
They transform the vibrations produced by sound into electrical signals that are transmitted to the brain. But as we age they die off. They are killed by loud noises, certain drugs and faulty genes. The holy grail in this quest is to find a way to bring them back to life.
One of those scientists leading the charge is Dr. Jeffery Harris. He is Chief of the Division of Otolaryngology-Head & Neck Surgery at the University of California, San Diego. Not only is he a renowned surgeon but he also leads a team of researchers who are studying the causes of deafness.
In this new video, Dr. Harris gives a clear and concise explanation of the current state of the research and offers more than a glimmer of hope:
Odd but intriguing research is underway at Colorado State University. Engineers are developing a mouth piece that can transmit the sensation of sounds to the tongue.
As anyone who has savoured a fine meal knows, the tongue is rich with sensory nerve cells. What if those cells could also be used transmit sound, or at least an interpretation of sound, to the brain bypassing the ears completely?
That’s concept the CSU researchers are working on and they produced this video to show how it might work.
An important new study reveals a tantalizing new clue about hearing loss.
Iron deficiency anemia (IDA) has been linked to hearing loss in a major study conducted by researchers at Penn State’s Milton S. Hershey Medical Center.
They studied over 300,000 people, ranging from the young to the elderly. Among the findings, the risk of sensorineural hearing loss was 82% higher among those with low iron levels in their blood.
Your bone marrow needs iron to produce hemoglobin for the red blood cells that carry oxygen throughout the body. Iron deficiency can cause symptoms ranging from fatigue to muscle weakness and maybe, just maybe, play a role in hearing loss.
But the study’s lead author, Kathleen P. Schieffer, emphasizes that, “Our study does not say that iron deficiency causes hearing loss, but only that there is a link between the two.”
She also does not recommend that anyone take iron supplements without first consulting a doctor.
The reason for the link is unknown but one theory is gaining ground. We know from animal studies that iron deficiency reduces the flow of hemoglobin to the cochlea and that the auditory nerve cells need a lot of oxygen.
The report concludes that “further research is needed to better understand the potential links between IDA and hearing loss and whether screening and treatment of IDA in adults could have clinical implications in patients with hearing loss”.
Another promising development in research into restoring hearing.
The key to restoring lost hearing is finding a way to re-grow hair cells in the cochlea. We’re born with about 30,000 of these tiny sound detectors and because of exposure to noise, age and some types of antibiotics they die off.
The good news: researchers around the world are working to develop techniques to regenerate hairs cells. Now comes word that a team at MIT, Brigham and Women’s Hospital, and Massachusetts Eye and Ear have discovered a combination of drugs that does just that. At least it works in mice.
“There have been a couple patients with hearing improvement, so we are definitely encouraged.” – Dr. Lawrence Lustig
There is no cure for sensorineural hearing loss, the type that most of us with aging ears suffer from. At least not yet. But as I’ve written about in earlier posts, a pioneering treatment may be on the way. It’s called CGF166. It’s the only gene therapy for hearing loss now undergoing human trials in the U.S. and early reports are promising. Here’s a progress report. Continue reading “CGF166 – The Latest News”
What’s going on between your ears when you’re losing your hearing? Emerging research is beginning to give us some revealing, and disturbing answers about brain function and hearing loss. But it also offers some hope.
First the bad news: Take a look at this picture.
On the left, is the brain of a person with normal hearing and the areas that process sound are lit up as they should be. But on the right is the brain of a person with mild hearing loss. As you can see there’s less activity and what there is has shifted to other areas. Continue reading “Mind Reading Hearing Aids?”
