Testosterone What Affects the Test
Reasons you may not be able to
have the test or why the results may not be helpful include:
What To Think About If the total testosterone level is low, more testing may be done to find the cause. The levels of other hormones made by the pituitary gland, such as
follicle-stimulating hormone (FSH) and
luteinizing hormone (LH), may be checked to see
whether a low testosterone level is caused by problems with the testicles or
ovaries or the pituitary gland. A really high level of
LH and a low level of testosterone often means that the testicles or ovaries
are not working properly. This is the pattern seen in women after menopause when their ovaries stop working. A low LH level and a really low or high testosterone
level may mean a problem with the pituitary gland.
