Measurement of hormone levels not related to blood or urine may
also yield information about infertility. For example, certain conditions
that are associated with abnormally high male hormones such as testosterone
or cortisonelike hormones can cause infertility. Also follicle-stimulating
hormone (FSH) and luteinizing hormone (LH) are two messenger hormones
that play essential roles in the delicate ovulation mechanism. If
these are presenting slightly reduced or elevated amounts or do
not fluctuate appropriately during the month, infertility may result.
The hormone prolactin (which plays an important role in breast milk
production) may be abnormally elevated and be the cause of infertility.
Treatment of this elevated hormone level with the drug bromocryptine
will in many cases cure the infertility.
A hysterosalpingogram
is a test used to study the uterus and fallopian tubes. It can be
done in a hospital or in the office of a radiologist. A speculum
is inserted into the vagina and the cervix is grasped with a tenaculum.
A dye-injection apparatus is then attached to the cervix, the dye
is slowly injected into the uterus and X-rays are taken. Most women
feel the injection of the dye to be about as uncomfortable as moderate
menstrual cramps. The X-rays show the internal outlines of the uterus
and fallopian tubes as the dye fills them. If there is any abnormality
in the shape or size of the uterus or a blockage in the fallopian
tubes, this may show up on the X-rays.
