What is the life expectancy of someone with Klinefelter Syndrome?

If You don't treat with TRT You can make cancer.

Research shows there can be a modest impact on life span. Typically 3-5 years less than other same age individuals without the condition. Lots depends on getting good medical care and management.

same as anyone else

I think that depends on family history, genetics. I haven't experienced any of the autoimmune conditions related to KS. If there is a family history of heart failure or diabetic conditions then that can directly effect a persons life expectancy. In my years of work in the Medical field I have seen 40 year olds who look 70 and 70 year olds who look 40. I firmly believe a lot of determining factors of ones life expectancy is related to family genetics. I don't know of any studies that give us a time-line on this subject. Personally my family history shows males living into their 90's, my father is 93 yo

I am 46 and still healthy and strong!

3-5 years shorter than someone your age.

with treatment normal, without shorter

I am 49. I would like to find a diet to help with my spare tire and breast tissue. I don’t want to take testosterone bec. of prostate problems. I was diagnosed when I was 15 and sent on my way. I never was helped out or told why I was so angry and why I couldn’t learn simple math. Now as a man I’ve learned to control my anger issues to an extent and I’ve always dealt with learning to a certain degree. All I want to learn about now is how I can improve my health and live the maximum amount of years as I possibly can. Any help with information would be greatly appreciated.

Just turned 61 years old and will be 62 in a few more months. I've had my share of learning disabilities as well as bulling by regular people. Used to think about suicide for the last 30 years of my life, but no more. Was also born with a congenital heart defect, never repaired medically. I think I am doing fine and have worked my way around these problems. Even tho I've had to lie on job applications in order to get work to support myself, even encountering harassment from other workers through out my life. After relating my problems to my family I was snubbed by them and have refused to see any of them for the past 20 years. I prefer to be alone and away from them even up to the point of death. There will be no viewing and no burial since I have chosen to be cremated.
