Luteinizing Hormone Production
LH is the pituitary signal that tells your body to produce testosterone or estrogen. Low pulsatility is a common root cause of low-T symptoms despite "normal" total testosterone—because the signal to produce more never fires strongly enough.
What this measures
How your DNA shapes luteinizing hormone production.
LH (luteinizing hormone) drives testosterone production in men and ovulation in women. LHB (the LH beta-subunit) and LHCGR (the LH receptor) shape both how much LH the pituitary produces and how strongly the testes or ovaries respond. FSHR adds context through the related FSH pathway. The collective network sets the strength of the reproductive hormone axis.
Carriers of common LHB and LHCGR reduced-activity variants are associated with lower endogenous LH signaling — and may experience subclinical hypogonadism in men or ovulatory irregularities in women, particularly under stress, undereating, or aging. Carriers of typical-function variants tend to maintain robust LH signaling under default conditions.
Adequate body fat (especially in women), nutrient status (zinc, vitamin D, magnesium), and stress management all support LH production. Severe caloric restriction, overtraining, and chronic stress all suppress the axis. Sleep is essential — most LH pulses happen during sleep, and sleep restriction directly reduces total LH output.
The "I trained really hard and my cycles stopped" or "my testosterone dropped without obvious reason" patterns often have an LH-axis suppression underneath. Which LHB/LHCGR variant pattern you carry decides whether default training and stress loads are tolerable or whether deliberate recovery and nutrient support is required to maintain the reproductive hormone axis.
Luteinizing Hormone Production is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the hormones spectrum — and what you can do about it: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

Autoimmune Thyroid Risk
Genetic predisposition to Hashimoto's or Graves' varies widely. If you're in the higher-risk group, early antibody monitoring can catch the process years before full disease expression—when lifestyle interventions still have leverage.
Read insight →Cortisol Production
Some people run naturally high on cortisol; others trend low. Neither is inherently bad—but each benefits from different stress-management strategies. High producers need more active recovery; low producers may need adaptogen support. One-size-fits-all stress advice ignores this completely.
Read insight →Cortisol Receptor Sensitivity
Same cortisol level, very different felt experience. High receptor sensitivity means stress hits harder even when cortisol is "normal." This explains why some people thrive in chaos while others burn out—and it's not about being weak. It's about wiring.
Read insight →DIO1 Activity
DIO1 handles the body-wide conversion of inactive T4 into active T3. Reduced activity is a common reason for persistent hypothyroid symptoms—fatigue, weight gain, cold intolerance—even when TSH looks "normal." Standard testing misses this entirely.
Read insight →DIO2 Activity
DIO2 produces T3 specifically in the brain and muscles. Low activity is one of the most common causes of brain fog and cold hands on standard thyroid treatment that looks fine on paper. If your labs are normal but you still feel terrible, this is often why.
Read insight →Dihydrotestosterone (DHT) Levels
DHT is the more potent downstream product of testosterone. High converters may see effects on hair loss, prostate health, or skin—and often benefit from DHT-blocking strategies before symptoms become problems. Low converters rarely need to worry about it.
