Thyroid stimulating hormone (TSH) is a
hormone produced by the pituitary gland.
Its task is to stimulate the thyroid gland
to produce thyroxin. Thyroxin is a very
important hormone responsible for many
functions in the body, including
reproduction. TSH is raised during two
principle scenarios. The first, when the
thyroid gland produces a low amount of
thyroxin, causes the pituitary gland to
react and want to stimulate the thyroid
gland to produce more thyroxin by
producing more TSH. In that case, TSH
levels are high and thyroxin levels are
low (or normal) in the body. The second
situation finds the pituitary gland
producing more TSH, regardless of the
level of thyroxin in the body. In this
cas,e both TSH and thyroxin levels are
high. Besides increased TSH, it seems that
you also have another hormonal disorder,
poly-cystic ovarian syndrome (PCOS).
Obesity and sterility are symptoms of
PCOS. You can check your blood levels for
testosterone, DHEA, and insulin at your
GP's office.
