Klinefelter Syndrome occurs when men are born with an extra X chromosome.

Often patients will have low testosterone levels resulting in low libido, breast development, small testes and small muscle tone.

They are likely to also have raised LH and FSH levels.

What type of condition is this?

Answer 0

Hypergonadotropin hypogonadism
Kline felters is a Primary Hypogonadism and Hypergonadtropic Hypogonadism because the testes cannot produce enough testosterone therefore there will not be a negative feedback mechanism to control LH and FSH. Hence LH and FSH rise above normal.

Androgen /hormone replacement therapy is the treatment
