Is there any way in which a pituitary tumor could cause a woman (in the early 30s) to secrete high lh levels (twice as much as fsh) and if so how?

LH production ? A pituitary tumor of sufficient size to create symptoms should have a prolactin level greater than 100. Increase pressure from a pituitary tumor will usually shut down normal pituitary hormone release, including LH. Prolactin is increased because shuting down the pituitary stops the inhibitory releasing factor, allowing increased prolactin. LH is elevated at ovulation, and is higher than FSH.
