Klinefelter Syndrome is a prenatal condition that occurs when men possess an extra X chromosome either as XXY or XYX. Believe it or not, this isn’t actually as odd as it sounds. Everyone starts as a female in the womb before one X chromosome eventually turns into a Y and turns the fetus from female to male. Usually Klinefelter develops because there were problems with the cells that normally would have created an XY chromosome. Although it isn’t fatal, this condition may cause emotional and physical problems.

Gynaecomastia

You’ve probably heard the term “gynecologist” before right? Well, the same Greek word, "Gynaeca", meaning woman, is the basis for the word “gynaecomastia”. So what does this have to do with Klinefelter Syndrome? Basically, this refers to breast enlargement in men. Although heavy eating and drinking may also cause it, a man with Klinefelter Syndrome may need surgical assistance to remove the enlarged breasts.

Delayed Puberty

If you’ve ever been around teenagers, then you’ve seen how fast boys can grow between the ages of 14 and 17. For those with Klinefelter, some never experience puberty while others begin to develop late. To be clear, not every case of a delayed growth spurt is the result of Klinefelter. Malnutrition, poor eating habits, and smoking are just some of the things that can delay puberty. When Klinefelter is responsible for the delay, however, it’s because estrogen is preventing the body from beginning puberty.

Weak Bones

Some kids climb trees and play sports to the point where bumps and bruises are basically a rite of passage. However, if the slightest mishaps are causing your child’s bones to fracture or break, there is cause for concern. Klinefelter causes the chromosome mixture to produce chemicals that contribute to overall weakness. A broken leg is hard to miss, but fatigue is also something to look out for. Because fatigue is so common, however, it isn't a definitive symptom.

Taller Than Normal Stature

Have you ever noticed how a lot of women have longer legs than men? Klinefelter introduces extra estrogen to the body that promotes similar leg growth in men. Because of its distinctly “feminine” appearance, this is actually one of the clearest signs of Klinefelter available. So is it possible to prevent this from happening? The good news is that doctors can prescribe testosterone supplements. But the bad news is that these medications do have limitations.

Unreasonable Weight Gain

Women often experience weight fluctuations due to estrogen. Generally speaking, men aren’t expected to gain weight to such similar extremes. Because men with Klinefelter produce almost as much estrogen as women do, they are exceptions to this general rule concerning weight gain. So if you have been working out and eating clean but not seeing any real improvements, this condition could be the reason for that.

Long, Thin Arms

Men often grow biceps and triceps tissue naturally as a result of puberty. However in the same way that many women have naturally thin arms, the same is the case with men who have Klinefelter. That being said, this isn’t necessarily a problematic symptom. But this is an irregularity that’s present in many men who have Klinefelter Syndrome.

Slow Motor Development

A lazy young child is something rare in itself and it's even rarer to see a child taking longer than usual to sit down or stand up. This complication appears during growth, resulting in even longer performance times of the simplest actions. It can be remedied with an extensive physical activity that would provide the child with entertainment and the inspired willpower to combat their difficulty.

Lack of facial and body hair

Aside from pubic hair, which is almost never influenced by the Klinefelter syndrome, impeded hair growth in most areas of the body (unrelated to actual scalp hair) is an almost clear display of excess estrogen. Testosterone supplements will help only in at the early stage of development, as that's when it can influence hair development. Later on, hair growth supplements can remedy specific areas, but they won't change much overall. This is closely related to delayed or inexistent puberty since that's when most of the hair growth takes place.

Small Penis and Small, Firm Testicles

Testosterone is vital to the development of reproductive organs. If the necessary amounts are not met on time during growth, this complication is bound to be present. In the beginning, boys mostly don't pay attention to this, as they likely attribute it to the fact that they're young. It will become apparent that they still have this issue in their teenage years if it's present. There really isn't a way to fix this problem, other than the already mentioned testosterone supplements in the early stages of development. The penis and scrotum will remain unexpanded at mostly the same ratio as during youth.

Infertility

We've left this for the end of the list is that it's the latest to be discovered. Most of the complications of Klinefelterlead to the invalidity of sperm. A lack of sperm overall is also related to this difficulty. Allow sex drive can also be attributed to it. With medicine constantly making progress, possibilities of infertile men having children are constantly increasing. It is still a primary concern of every Klinefelter victim.
