Purpose of the FSH and LH Blood Test
An FSH and LH test is a valuable tool if you’ve been struggling to conceive. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are both produced in the brain’s pituitary gland and are key indicators of fertility. In women, FSH stimulates egg production and helps regulate menstrual cycles; in men, it stimulates sperm production. LH also works with FSH and estrogen to help women ovulate and menstruate regularly. Fertility tests such as this one are helpful if you need answers to your infertility questions.
What Does the FSH LH Blood Test Measure?
Who Should Take an FSH LH Test?
Measuring LH and FSH in a blood test is advisable for women or men who are dealing with infertility. Women can also take this test if they have irregular menstrual cycles; men may want to be tested if they have low sperm count, decreased sex drive, or low muscle mass. The FSH and LH blood test can also be used by anyone who has symptoms of pituitary or hypothalamic disorders, which can affect fertility. These symptoms include unexplained weight loss, fatigue, and a feeling of weakness.

FSH and LH Results
For women, high levels in an FSH LH blood test may indicate reproductive issues such as polycystic ovary syndrome or Turner syndrome, which can both cause infertility. High levels also could signify that ovulation has ceased, and a woman may be entering perimenopause or menopause. For men, high test levels could indicate testicular damage or the genetic disorder Klinefelter’s syndrome.
Low test results can point to a pituitary problem in both men and women. Women may also have malnutrition or an eating disorder if they have low FSH and LH levels, while men could also have an issue related to the hypothalamus.
