What are erection problems?

A man has erection problems if he cannot get or keep an erection that is firm enough for him to have sex. Erection problems are also called erectile dysfunction or impotence.

Erection problems can occur at any age. But they are more common in older men, who often have other health problems. Treatment can help both older and younger men.

What causes erection problems?

Erection problems may be caused by physical problems, such as injury to nerves or loss of blood supply to the penis.

They can also be linked to other health problems. These include diabetes, high blood pressure, high cholesterol, and atherosclerosis. Erection problems can also be linked to problems with the nervous system, such as multiple sclerosis and Parkinson’s disease.

Many medicines for other health problems may cause erection problems, but most do not. If you recently began taking a new medicine and started having erection problems, this could be a side effect of the medicine. Talk with your doctor. He or she may be able to change the dose or type of medicine you take.

Men who drink too much alcohol, smoke, or use illegal drugs also are at risk for erection problems.

Anxiety, stress, or depression can cause erection problems.

Other causes include surgery, such as for prostate cancer, or injury to the pelvic area.

What are the symptoms?

The only symptom of an erection problem is being unable to get and keep an erection that is firm enough to have sex. But even with an erection problem, a man may still have sexual desire and be able to have an orgasm and to ejaculate.

How are erection problems diagnosed?

Your doctor can find out if you have an erection problem by asking questions about your health and doing a physical exam. Your doctor will want to know if the problem happens all the time or just from time to time. The exam, lab tests, and sometimes mental health tests can help find out the cause of the problem.

How are they treated?

There are a number of treatments for erection problems. Doctors usually start with lifestyle changes and medicines. They usually don’t advise surgery or other treatments unless those first steps don’t help.

Treatment can include:

  • Making lifestyle changes, such as avoiding tobacco, drugs, and alcohol. It may also help to talk about the issue with your partner, do sensual exercises, and get counseling.
  • Finding and then stopping medicines that may be causing the problem. In some cases you can take a different medicine that does not cause erection problems.
  • Taking prescription medicine that can help you get erections. These include pills such as Viagra, Levitra, and Cialis. Check with your doctor to see if it is safe for you to take Viagra, Levitra, or Cialis with your other medicines. These can be dangerous if you have heart disease that requires you to take nitroglycerin or other medicines that contain nitrates.
  • Taking medicines and getting counseling for depression or anxiety.
  • Using vacuum devices or getting shots of medicine into the penis.
  • Having surgery to place an implant in the penis.

Can you prevent erection problems?

Because erection problems are most often caused by a physical problem, it’s important to eat healthy foods and get enough exercise to help you stay in good health.

To reduce your risk of having an erection problem, do not smoke, drink too much alcohol, or use illegal drugs.

You may be able to avoid erection problems related to anxiety and stress by talking with your partner about your concerns. This may help you relax.

CHICAGO: A personalized vaccine made using tobacco plants — normally associated with causing cancer rather than helping cure it — could aid people with lymphoma in fighting the disease, US researchers said.

The treatment, which would vaccinate cancer patients against their own tumour cells, is made using a new approach that turns genetically engineered tobacco plants into personalized vaccine factories.

“This is the first time a plant has been used for making a protein to inject into a person,” said Ron Levy of Stanford University School of Medicine in California, whose research appears in the journal Proceedings of the National Academy of Sciences.

“This would be a way to treat cancer without side effects,” Levy said in a statement on Monday. “The idea is to marshal the body’s own immune system to fight cancer.”

Levy was working with a team of scientists from the now defunct Large Scale Biology Corp, which helped fund the study, as well as Bayer AG’s Bayer HealthCare, CBR International Corp, Integrated Biomolecule Corp, The Biologics Consulting Group Inc and Holtz Biopharma Consulting.

They were working on a type of cancer known as follicular B-cell lymphoma, a kind of non-Hodgkin’s lymphoma that attacks the immune system. The cancer makes a specific antibody that is not found in healthy cells.

The technology exploits the tobacco plant’s vulnerability a virus that only attacks tobacco plants, which most people associate with causing cancer, and not curing it.

The researchers altered the virus, adding the specific antibody gene from a patient’s cancer cells. Then, they infected the tobacco plants with the gene-carrying virus.

“You scratch it on the leaves and it turns the plants into a protein-producing factory for the protein of interest,” Levy said.

Other approaches that use animals to make the vaccines can take months, but the plant-based approach is very fast.

“A week later, you extract the protein. It’s that fast.”

In a test of 16 patients with follicular B-cell lymphoma, 70% of people injected with a made-to-order vaccine developed an immune response, and none had any side effects.

Levy said the study suggests personalized cancer vaccines could be produced efficiently and cheaply using plants. The early-stage study only focused on the safety and immune-stimulating ability of the plant-produced vaccines.

Future studies will be needed to show how effective they are as a treatment.
