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.
What this measures
How your DNA shapes dihydrotestosterone (dht) levels.
SRD5A2 codes for 5-alpha reductase type 2 — the enzyme that converts testosterone into DHT (dihydrotestosterone), a more potent androgen that drives certain tissue effects more strongly than testosterone itself. AR (androgen receptor) sensitivity further shapes how strongly tissue responds. DHT is essential for some functions and a driver of unwanted effects in others — pattern hair loss, BPH (benign prostatic hyperplasia), and acne all run partly through DHT.
Carriers of SRD5A2 high-activity variants are associated with higher DHT-to-testosterone conversion and more DHT-driven effects (faster hair-loss progression, BPH risk, acne severity). Carriers of AR high-sensitivity variants are associated with stronger tissue response to whatever DHT is present. The combination shapes both circulating levels and how much they matter.
Saw palmetto, pumpkin seed oil, and certain dietary patterns moderately reduce 5-alpha reductase activity. 5-alpha reductase inhibitors (finasteride, dutasteride) directly block conversion and are FDA-approved for hair loss and BPH — with side-effect profiles that vary across variant patterns. Adequate zinc supports the broader androgen network. Stress and insulin resistance both shift the testosterone-to-DHT balance.
Hair loss patterns, prostate symptoms, and acne severity often track to DHT pathway variants more than to "low testosterone." Which SRD5A2/AR pattern you carry decides whether DHT is a driver worth addressing — and whether the right intervention is dietary, topical, oral pharmacological, or simply awareness.

Dihydrotestosterone (DHT) Levels renders as a dark-background card with a color marker calibrated to your specific variants. The card opens with the gene mechanism, shows your result at a glance via that marker, and closes with a practical, mechanism-led recommendation — what to eat, what to time, what cofactors to support.

In context
Sex Hormones: the 6-insight cluster.
Dihydrotestosterone (DHT) Levels is one finding in a tightly-related cluster. Mosaic sequences the other 5 alongside it so you see the whole biology — not an isolated data point.
- Estrogen MetabolismYour liver processes estrogen through multiple pathways—some produce protective metabolites, others produce more aggressive ones. This ratio matters for long-term health and explains why some people feel great on the same hormone levels that cause problems for others. Cruciferous vegetables and targeted supplements can shift the balance.
- Estrogen Receptor SensitivitySame estrogen level, dramatically different response. High receptor sensitivity often underlies severe PMS, difficult perimenopause, or intense menopausal symptoms. It's not in your head—it's in your receptors.
- Luteinizing Hormone ProductionLH 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.
- Sex Hormone Binding Globulin (SHBG) LevelsSHBG binds sex hormones and takes them out of circulation. High levels can mask what's really low bioavailable testosterone or estrogen, even when total levels look fine. This is the "hidden half" that standard hormone panels ignore.
- Testosterone to Estrogen ConversionAromatase enzyme activity determines how much testosterone converts to estrogen. High converters—often signaled by weight around the middle—benefit from natural aromatase inhibitors like zinc, DIM, and weight training. Low converters rarely need to think about it.
Questions people ask
About Dihydrotestosterone (DHT) Levels.
- How does my DNA influence dihydrotestosterone (dht) levels?
- The DIO2 thyroid-conversion enzyme that turns inactive T4 into active T3. The COMT and CYP1A1 enzymes that move estrogen through Phase I detox. The SHBG variants that bind or release testosterone. The CYP17A1 and HSD3B2 nodes in the steroid synthesis cascade. Your "normal" labs may sit on top of a genome that needs a different intervention.
- What kind of test do I need to see my Dihydrotestosterone (DHT) Levels result?
- Whole-genome sequencing at 30× clinical depth. Consumer SNP-chip tests like 23andMe or AncestryDNA only read ~0.02% of your DNA and miss most of the variants this analysis needs. Mosaic reads all 3 billion base pairs and produces the full 108-insight report.
- How is Dihydrotestosterone (DHT) Levels different from clinical lab testing?
- Clinical labs measure downstream biomarkers — blood levels, hormone values, metabolic byproducts — at a single point in time. Genomic insights like Dihydrotestosterone (DHT) Levels reveal the underlying variant that shapes the biology, which is constant for life. The two are complementary: labs show the current snapshot; genomics shows the long-term tendency and where lifestyle leverage is highest.

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.

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.

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.

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.

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.
