You probably know testosterone (T) plays an important role in how boys physically develop into men. But is that all you know? What happens when a man's T levels are off? Are there symptoms men should look for? And what are the treatment options? Dr. Bobby Kahlon, MD, Renown Medical Group provides answers in a Testosterone Q&A.   What does testosterone do for men?  "Testosterone is known as the 'manly hormone' for a reason," says Dr. Kahlon. "Though women also naturally produce small amounts of it, men produce testosterone at much higher concentration levels. And it affects men in more physical and obvious ways. How much hair a man has on his chest, how deep his voice is, or how muscular he is are all attributable in some way to testosterone. It's also responsible in large part for sex drive and bone strength and affects how men think, learn and experience their surroundings."  Testosterone in men:   Powers virilization (male physical characteristics) and sexual function Builds muscle mass and strength  Supports bone density  Improves cognition  T Trivia: Discover Magazine reveals that “manly” testosterone and other sex hormones evolved long before we did — 500 million years ago — from the ultimate “female” hormone, estrogen. Can you have too much or too little testosterone?  Though high testosterone isn't a concern for most men, low testosterone or low T occurs more frequently and develops for two primary reasons.  Dr. Kuhadiya explains, "Subnormal testosterone concentrations occur either due to pituitary or testicular failure and the causes for each need to be discussed with your physician."  Pituitary failure: Approximately one-third of men with obesity, type 2 diabetes, or metabolic syndrome (which includes increased blood pressure, high blood sugar, excess body fat around the waist, and abnormal cholesterol or triglyceride levels) have low free — or "bioavailable" — testosterone. These health conditions can cause the pituitary gland to "fail" to release follicle stimulating hormone (FSH) and luteinizing hormone (LH) which are essential for triggering testosterone and sperm production. And that can cause low testosterone (hypogonadism). Testicular failure: Though less common than pituitary failure, testicular failure may also be responsible for low T. It's caused by diseases or illnesses affecting the testicles, injury or trauma to the testicles, or certain medicines and treatments such as chemotherapy or opioid pain medication. Providing your complete medical history to your doctor is always the first step toward a proper diagnosis.  What are the symptoms of low T?  The following indicators could be a sign that you have low T, say the doctors.  Lack of motivation and determination, including mild depression  Loss of physical endurance and muscle strength  Loss of or diminished early morning erections  Reduced libido (sex drive)   Erectile dysfunction (ED — difficulty achieving or maintaining an erection)   Gynecomastia (male breasts)  Small testes  T and Time: T levels in men naturally begin to decline by about 1% a year starting at age 30.  How do you test for low T?  "There are different methods for testing testosterone levels," says Dr. Kuhadiya. "Each approach uses a blood sample to evaluate total testosterone, which includes free and attached testosterone that combines with proteins albumin and sex hormone-binding globulin (SHBG). For the most accurate results, testing is based on samples collected in the morning after fasting, and from tests on two different days."  What treatment options are available?  "Well, your best natural option may be YOU," says Dr. Kahlon. "Men with pituitary failure are often able to treat their low T by losing weight to increase levels of the hormone. And even if you don't lose weight, exercise can help boost your testosterone. Unfortunately, if you have testicular failure, weight loss and exercise may not have the same effect."  So, are there other options? "You may want to consider Testosterone Replacement Therapy (TRT)," says Dr. Kuhadiya. "TRT is only available to men who are hypogonadal — with a clinical diagnosis of low T. Injection, gel, skin patch and nasal spray are available TRT options. The best option is the one that works best for the patient. Convenience, insurance coverage and cost are all factors to consider." Dr. Kahlon's TRT preference? Daily gel treatments, which are applied directly to the skin. On the other hand, Dr. Kuhadiya recommends intramuscular injections, which take place once a week or every two weeks.  But both doctors agree on this: physicians and their patients need to weigh the benefits and risks of TRT before proceeding with treatment — especially if your low T condition may require lifelong treatment. "In my clinical practice, I have seen some very good long-term results with an improved quality of life," says Dr. Kuhadiya. "However, in certain situations, TRT may increase the risk of heart disease and is not recommended for men with a history of prostate cancer." Dr. Kahlon adds, "Patients receiving any type of hormone therapy need to be closely monitored throughout the treatment process for any changes in their health."   How do you feel about steroids and T boosters?  "I don't recommend them, certainly not for hypogonadism," advises Dr. Kahlon. "There is no evidence to support anabolic-androgenic steroids or testosterone boosters as a safe or effective treatment for low T in men."  "In fact, there continues to be emerging evidence they may lead to side effects that could potentially harm the liver and the pituitary and endocrine functions of the body," warns Dr. Kuhadiya. "And that damage may be irreversible."

Seeing a snake while exploring northern Nevada’s trails is somewhat rare and the chance of a snakebite is even less common. However, it’s important to make sure you’re ready for snakes and know what to do in case of a snakebite. Hiking the rugged, stunning and varied landscapes of northern Nevada is a huge draw for many who live here. But it’s important to stay alert and be prepared while you’re out exploring the natural habitats of wildlife, especially if you encounter a snake or get a snakebite. As you prep for your next outdoor adventure, remember these three tips to stay safe in Nevada’s wilderness. 1. Leave snakes alone In general, if you don’t mess with snakes, they won’t mess with you. Seeing a snake is fairly uncommon because of their body camouflage and secretive nature, which are their first defenses in evading predators. According to the Nevada Department of Wildlife (NDOW), most snakebites happen when a person tries to capture or kill the snake. Nevada is home to 52 species of snakes and reptiles, according to NDOW. Only six can be dangerous to people and pets: Western Rattlesnake (this is the most common type of venomous snake in northern Nevada, especially around Yerington and Fallon) Sidewinder Mohave Rattlesnake Speckled Rattlesnake Western Diamondback Gila Monster (these live in southern Nevada’s Mojave Desert) Venomous snakes, like the rattlesnakes, have a wide head and thick body. Non-venomous snakes are usually more slender and have a narrow head. If you see a snake on the trail and you aren’t sure if it’s venomous or not, it’s best to be safe and leave it alone by moving away slowly. 2. Wear the right gear and take care where you walk NDOW and the U.S. Department of Agriculture suggest doing the following to decrease your chances of a snakebite: Wear over-the-ankle boots, thick socks and loose-fitting long pants. Stick to trails and stay out of the bushes or tall grass. Don’t step where you can’t see. If going over a fallen tree or large rock, step on it. Don’t jump over it. A snake might be lying on the other side. Always check stumps or logs for snakes if you’re going to sit on it. If you see one or hear a rattle, move away from the area slowly. Don’t run or make any sudden movements. Don’t handle or move a recently-killed snake as it can still inject venom. And for your dog, the best way to prevent a snake bite is to keep it on a leash. 3. Know what to do (and not do) if you get a snakebite Renown Health primary care physician Aaron A. Bertalmio, MD, reminds us the odds of getting a snakebite are very low. Roughly 7,000 to 8,000 people get bitten annually and only 5 percent die according to the U.S. Food and Drug Administration. But in the event of a snakebite, here’s what to do: Get medical help as soon as possible Stay calm to help keep your heart-rate low Remove constrictive clothing or jewelry Clean the wound with soap and water if available Cover the snakebite with dry, sterile cloth or adhesive bandage if available Keep the bite snakebite area level and below your heart if possible WHAT NOT TO DO IF YOU GET A SNAKEBITE: Apply a tourniquet (a tool used to stop arm or leg blood flow) Ice the bitten area Suck out the venom You’re now prepped and ready on what you need to know about Nevada’s slithery friends so you can stay safe and enjoy the outdoors!
