Luteinizing hormone (LH) is produced in and released from the anterior pituitary gland. It plays a key role in ovulation in women and testosterone production in men.
Working in the ovaries, luteinizing hormone works in unison with other hormones to stimulate follicle growth and the egg to release. Following conception, LH supports progesterone production to help sustain the pregnancy.
In men, LH works in the testes to promote testosterone production. Testosterone has a major part in sperm production, as well as giving men their distinctly male characteristics- like a deep voice and facial hair.
You probably don’t think about luteinizing hormone much. It works in the background to keep things running smoothly. Levels have to be just right or problems can occur. And when LH doesn’t work right- it can lead to infertility.
When LH levels are too high in women, it can lead to overproduction of testosterone. This is often associated with ovulatory disorders like polycystic ovary syndrome (PCOS). If there is too little luteinizing hormone, follicle stimulation and egg release in women and sperm development in men may not occur.
The most obvious symptom of abnormal LH levels is difficulty conceiving. Other than infertility, symptoms of abnormal LH levels include periods that are significantly late or missed in women and low sex drives or testosterone levels in men. If you are experiencing any of these symptoms, our OBGYN may suggest a blood test to check your luteinizing hormone levels.
If tests show abnormally high or low LH levels, our OBGYN will work to determine why the levels are off. Levels that are too high could mean a problem with the ovaries or testes. Lower than usual LH levels may mean something is wrong with the pituitary gland. Sometimes, hormone therapy can correct these issues and help you conceive.
Talk to an OBGYN at URANJ if you are experiencing symptoms of abnormal LH.
