Is there something wrong with ovaries or hormone system if I have ovarian insufficiency?

EARLY menopause. Ovarian failure or 'insufficiency' is a really another name for menopause (which may be premature if <40 yo). Normally the pituitary gland (in the brain) sends 2 hormone messengers FSH & lh to 'tell' the ovary to make estrogen/'female' hormones. When the ovary 'fails' =estrogen levels drop and fsh/lh levels rise confirming ovarian 'insufficiency' . Treatment with 'hormones' is optional.
