FSH and LH are hormones produced in a gland in the brain (the pituitary gland). The LH (male hormone) is necessary for producing testosterone (male hormone). They stimulate the testicles to work. These two hormones are used for work-ups for infertility. They are also used to help determine if there is too little male sex hormone (testosterone) being produced. If the LH hormone is elevated, it means that the male gonads are not working properly and stimulation by LH is not causing the testicles to make enough hormone. If the levels are low, it means that the brain is not producing enough hormones. This means there is not enough LH to tell (stimulate) the testicles to produce more hormone.
PREPARATION FOR TEST
No preparation or fasting is necessary.
Values may vary depending on assay method.
Luteinizing hormone: 1.24-7.8 (international units/L)
Follicle-stimulating hormone: 1.42-15.4 (international units/L)
Male Child (aged 1-10 years )
Luteinizing hormone: 0.04-3.6 (international units/L)
Follicle-stimulating hormone: 0.3-4.6 (international units/L)
Ranges for normal findings may vary among different laboratories and hospitals. You should always check with your doctor after having lab work or other tests done to discuss the meaning of your test results and whether your values are considered within normal limits.
MEANING OF TEST
Your caregiver will go over the test results with you and discuss the importance and meaning of your results, as well as treatment options and the need for additional tests if necessary.
OBTAINING THE TEST RESULTS
It is your responsibility to obtain your test results. Ask the lab or department performing the test when and how you will get your results.
