Problem: Article: Testosterone naturally peaks in adolescence and young adulthood and drops off as you age. If a blood test reveals that you have low testosterone levels, there's a good chance this could be the culprit behind your erectile dysfunction. Your doctor will likely recommend natural lifestyle changes first, such as losing weight or increasing muscle mass. If your testosterone levels are lower than average for your age, they may prescribe taking supplemental testosterone.If you're experiencing low testosterone levels as a result of aging, remember that this is completely normal. It's not currently advised to take testosterone as a way of addressing this. Your doctor may prescribe you medication that works by increasing the blood flow to your penis, and thus helping you maintain an erection. Medications commonly used to treat ED include Viagra, Cialis, and Levitra.  If your doctor prescribes Cialis, your doctor will likely recommend that you take 10 to 20 mg at least 30 minutes before sexual activity. You should not take the medication if you experience severe hyperactivity to the medication or if you are using nitrates, such as nitroglycerin, for chest pain. If your doctor prescribes Levitra, then you will need to take it with or without food 60 minutes before sex. This medication should not be taken with nitrates either. You may also ask your doctor about the use of mechanical aids to help you achieve and maintain an erection. Some men use vacuum devices and constriction rings to aid erections. The vacuum is placed over the penis and pumps out air, drawing blood to the penis and causing an erection.  This is maintained by placing a band or ring at the base of the penis, that keep it erect for up to thirty minutes. This can, however, be a uncomfortable and awkward way to treat ED. An alternative method that you may be advised on by a doctor is penile injection therapy. For this you will be trained by the doctor how to inject your penis with medicine that relaxes the blood vessels and promotes the blood flow that causes an erection. This treatment has been shown to be effective at treating a range of issues both physical and psychological.  Potential side effects include scarring, and the risk of sustained and painful erections if improperly dosed. You may experience high blood pressure and dizziness as a result of injection therapy. Your doctor may suggest you try this treatment, which involves placing a suppository into the urethra. The suppository contains alprostadil, which is then absorbed into the blood stream, relaxing blood vessels and improving blood flow into the penis. This treatment is thought to be less effective than the vacuum devices, or injection therapy. If the other treatments have not proven successful, your doctor may recommend a surgical procedure that will involve an inflatable penile prosthesis being implanted into your penis. Typically a pair of inflatable cylinders are inserted into the penis, which can be pumped up and deflated using a connected device that is inserted into the scrotal sac.  The prosthesis does not change the sensation on the skin, or effect the man’s ability to orgasm and ejaculate. The surgery involves two small incisions and is not noticeable after healing.
Summary: Get a blood test to evaluate your testosterone levels. Consider oral medication. Investigate mechanical aids. Use penile injection therapy. Ask about transurethral pharmacotherapy. Evaluate surgical options.

INPUT ARTICLE: Article: If a cat is displaying aggressive behavior early in life you should try to change it quickly. Eliminating aggressive behavior in a young cat or kitten can prevent it from becoming habit. Even if a cat is older it is still worth your time to try and reduce its aggression. The cat will simply take more time to change its behavior than than a young cat would. In order to minimize the cat's aggression, you need to get to the root of the problem. Start by thinking about what has changed in the animal's life that may be giving it anxiety. Also be on the lookout for what happens to and around the cat right before an episode. If you can figure out where the aggression is coming from, you may be able to mitigate it. Some common reasons for aggression include:  Fear Defensiveness Conflict with other animals Redirected anger Territorial feelings Predatory aggression Overstimulation Rough play excitement Maternal protection General irritability Pain Thyroid issues Lack of attention Change in location Past trauma There are typically some warning signs that your cat is going to become aggressive before it strikes out. By identifying them, and stopping the stimulus that is causing the behavior, you can sometimes avoid the incident altogether. While each cat's behavior before an aggressive episode can differ, some common signs include:  Crouching or squatting Tucking the head down Wide eyes with dilated pupils Retracted whiskers Hissing or spitting Putting its hackles up Ears flattened back If you have figured out that your cat's aggression has a specific cause, make any possible adjustments that will eliminate the cause. There are some issues that can be eliminated by making changes to the cat's living situation or interactions. For example, if your cat gets aggressive when you play roughly with it, stop that kind of play. If your cat has a hard time with other animals, it might be best to keep it as an only pet. As you are trying to change your cat's behavior, it is important to let the animal know when it is doing a good job. Rewarding the cat with treats or a game it likes to play when it is acting nicely is a good way of showing it the right kind of behavior. For example, if your cat gets aggressive when it is petted for too long, reward it when it doesn't exhibit this behavior. Pet it lightly for a few moments in your lap and before the interaction goes awry set it on the floor. Then give it a treat for its good behavior. If you repeat this process, the cat will eventually learn that it gets something it likes if it does not strike out in anger.

SUMMARY: Start your intervention early. Figure out what is causing the aggression. Identify the signs that your cat is about to become aggressive. Make adjustments that will ease your cat's aggression. Reward good behavior.
