What is Luteinizing Hormone (LH) and Testosterone
What is Luteinizing Hormone &
The Productions of Testosterone
If you google the word Luteinizing Hormone or (LH), most of the articles you will find talks about the role of luteinizing hormone in women. There is very no info about the part of Luteinizing Hormone in men. While it may seem like a female hormone due to its role in ovulation, a surge of Luteinizing Hormone is a trigger that causes the ovary to release the egg, in the body. If you’ve been trying to conceive or have a baby your wife, significant other may be monitoring her Luteinizing Hormone levels. If she has trouble with ovulation, your doctor may prescribe medications that help with ovulation.
Many of this medication help stimulate the body to produce more Luteinizing Hormone (LH) and its cousin hormone, Stimulating Follicle Hormone (FSH). If you are not trying to conceive, or get pregnant, she may be on hormonal birth control pills. These pills prevent ovulation by blocking Stimulating Follicle Hormone and Luteinizing Hormone. It is one of the manliest hormones in your body. You can think of Luteinizing Hormone as a tiny drill sergeant that commands the Leydig Cells in the testicle to produce testosterone. When Luteinizing Hormone is present, the Leydig Cells generate Testosterone, when it is not, they don’t. Luteinizing Hormone is commander and chief of your Testosterone and critically crucial for sperm production count, muscle building, and overall sexual health.
Male hormones have a clinical nature to them. Luteinizing Hormone (LH) signals the testicle to produce Testosterone. Testosterone seeps out of the testis and into the bloodstream, where it circulates the body and put to good use. Manly things like growing chest hair, increase muscle and your voice deep are some of the effects.
The brain monitors the blood testosterone levels;
- If they drop too low, it will send a signal to the pituitary gland to send out more Luteinizing Hormone (LH) to kick start testosterone production.
- If your testosterone is chronically low (as in the case with hypogonadism or Low Testosterone), the brain will respond by increasing the level of Luteinizing Hormone (LH).
- If testosterone is chronically higher (as in the case with using testosterone therapy, other performance enhancers or steroids), the brain will shut down production of Luteinizing Hormone (LH). When testosterone therapy is stopped, without post-therapy, men can experience a “crash” as Testosterone levels plummet, but with a post-therapy, the brain lags in re-starting the machinery to generate Luteinizing Hormone.
To measure Luteinizing Hormone (LH) levels, you will need to get blood work in a hormone clinic done. Because, doctors will order blood to estimate a panel of hormones which usually includes Stimulating Follicle Hormone, Luteinizing Hormone, Testosterone, Estrogen and They may also add Estrodial, Prolactin which will provide additional information into the insight into your hormonal health and a physical to know your body composition.
In a typical day, Luteinizing Hormone (LH) and Testosterone levels cycle from high to low. When getting blood work done to measure hormone levels, it is important to note the time of day that the analysis was performed to understand the values better.
Testosterone naturally will peak first thing in the morning (partially responsible for morning “wood”). For this reason, doctors prefer to regulate hormones between 8-10am to get a snapshot of your hormone panel profile when Testosterone level is likely to be highest.
When preparing for a Luteinizing Hormone test and to sure your doctor is aware of a few things like:
- Current Prescription Taking: Current or past use of testosterone therapy. (If you are using anything at the gym or in supplements stores and you aren’t quite sure), you should bring it with your doctor about the appointment.
- The Use Of Marijuana or THC: It may decrease the number of hormones levels, including Luteinizing Hormone.
- Medical Radioactive Tracer: This can interfere with the test
- Normal levels Luteinizing Hormone Range For Adult Males: 1–10 mIU/mL.
They are different labs report different reference ranges, and based on the exact way that they perform the blood work test. From a review of various lab reports, Values lower than 1.0 or higher than 10.0 typically indicate some problem.
For average men, Luteinizing Hormone (LH) typically falls somewhere between 4-7mIU/mL with drops and surges (about 6) throughout the day. Values below 4 and above seven may be considered borderline, and are useful to look at when compared to other hormones, particularly Testosterone and Prolactin.
In the studies that we have reviewed and found that these types of conditions have shown, and can significant drops in testosterone levels and minimal effect in Luteinizing Hormone (LH). Occasionally, Luteinizing Hormone may show up a little low, but often it is entirely in the normal range.
Therefore, low testosterone levels accompanied with normal Luteinizing Hormone (LH) levels often indicate the cause of Low Testosterone can tremendously help to diagnose the condition and also help to create a game plan for treating the cause while managing symptoms of low Testosterone.
Whats the Causes of high Luteinizing Hormone in Men?
If Luteinizing Hormone (LH) is high and testosterone is low. Then some damage is causing the testicle, or the pituitary gland is trying to compensate by going into overdrive and flooding the balls. With extra Luteinizing Hormone in hopes that it will encourage higher Testosterone production. In cases like this, Luteinizing Hormone levels are often off the charts high sometimes double or triple the average values.
Common causes for this include:
- Chromosome Abnormalities: Such as Klinefelter’s syndrome
- Childhood Problems: Such as testicle or testicular torsion, The injury that causes significant damage to testicular tissue
- Viral Infection: (most commonly mumps) that damages the testis.
- Radiation exposure or chemotherapy
- Testicular cancer
- Borderline High Luteinizing Hormone (LH) levels
Medications or untreated autoimmune disorders can cause slightly elevated Luteinizing Hormone (LH) levels (8.0 – 10.0 range). Some studies have linked Celiac’s Disease with elevated somewhat Luteinizing Hormone (LH). Men with the untreated disease can have moderately high Luteinizing Hormone levels, that usually return to normal upon starting a gluten-free diet.
What causes low Luteinizing Hormone in Men?
The most common reason for Luteinizing Hormone deficiency in men is the use of external androgens (testosterone, other performance enhancers or non-medication). External androgens can trick the brain into thinking the body is producing naturally high levels of testosterone which low down production of luteinizing hormone (LH) and consequently natural testosterone production.
The second most common cause of low Luteinizing Hormone (LH) levels is a health issue, and can directly impact the function of the pituitary in the brain, Most common causes of the pituitary malfunction can include genetic conditions, such as Prader-Willi Syndrome or Kallman’s Syndrome and can cause other problems like:
- Pituitary tumors (cancerous and benign)
- Head trauma
- Various Medications
- Auto-immune disorders
- Borderline low Luteinizing Hormone (LH) results
Luteinizing Hormone levels in the 1.0 – some things can cause 3.0 range. Like, reduce temporarily imbalance hormones: such as overtraining, endurance. They are significantly under or overweight Alcohol consumption spikes in insulin medications or other drugs. High-stress Chronic conditions: that can cause hormone imbalance: such as diabetes, insulin resistance, various auto-immune disorders and can create borderline or low levels of Luteinizing Hormone (LH).
