Brief Answer:
Normal Physiologic response

Detailed Answer:
You are concerned about your penis shrinking in size while exercising or exerting yourself. This is a normal physiological response.

When you are exercising your body is needing to concentrate all it energy and blood supply to the muscles.. That shift in blood flow takes blood away from your intestines and inner organs and puts the majority of it to the muscles of your arms, legs, heart and lungs. The last place blood is needed will be the penis. This shunting of blood is called the fight or flight response. Your body takes blood to where it is needed the arms and legs heart and lung to prepare for an emergency like having to fight your way out of something or to run away from something. The extra amount of blood to the muscles help give you an edge for escape. Your penis is not needed during those episodes and hence blood is shunted away from the non essential parts to the essential parts. This is all very normal and nothing to be concerned about.

Dear Dr.

Then why is it that this just started to happen about a year ago. It's like when I bend over or do anything strenuous. My penis shrinks to nothing. I am out of shape and carrying some extra weight. But I get exhausted so quickly, and then the shrinking. This never used to happen. What can I do about this ?

Brief Answer:
Poor conditioning

Detailed Answer:
If you want to improve your health then you need to start a regular exercise program and diet. Your penis is shrinking during the exercise because your body is so out of shape. The reason it is happening now is because you have reached a point in your health that overall condition is poor. There is no medication or other treatment that is going to help. You are in control here and you mentioned that you are out of shape and only you can fix that.

To start a regular exercise program I recommend walking daily. Start slow 15 minutes daily and gradually increasing to 30 and sixty minutes. If you are involved in a gym start with your trainer slowly and gradually increase your time. Don't try to over exert because you will become discouraged and stop. Please take your time to get up to a good healthy exercise program.

Also start with a good diet. Avoid concentrated sweets like pop, beer or fast foods. Take the time to make good healthy meals low in fat and high in protein. With time you will loss weight and feel healthier.

Once you do these measures and your health improves your overall sexual life will also improve.
