7 Genetic Signs of Hormonal Imbalance and How to Regain Control

Published on: Jul 21, 2025 | Updated on: September 08, 2025 | by 3X4 Genetics

You’ve cleaned up your diet. Taken the supplements. Tried to sleep more, stress less, move consistently.

But your body still feels… off.

Cycles that don’t sync. Mood swings that hit out of nowhere. Energy that crashes by 3 p.m.

Hormonal imbalance affects men and women alike, and when nothing seems to work, it can feel like your body is fighting you for no reason.

But there may be a reason. One that’s built into your DNA.

Your genes help shape how your body produces, metabolizes, and responds to hormones like estrogen and testosterone.

And when your genes influence those pathways in certain ways, your body may send signals, like weight that’s harder to shift, unpredictable cycles, or irritability, that something’s out of sync.

In this article, we’ll break down seven key genetic systems that affect hormonal balance and explore how DNA testing can help you better understand what your body may need.

Why Your Hormones May Be Out of Sync (Even When You're Doing Everything Right)

Hormonal imbalances are incredibly common and highly individual.

Traditional tools like blood tests, symptom tracking, and supplements can help, but they rarely explain why the same issue shows up so differently in different people.

That’s where your DNA comes in. Your genetic makeup can influence how your body:

Produces hormones like estrogen and testosterone
Metabolize and clear those hormones
Response to hormonal signals through receptor sensitivity
May handle inflammation that disrupts feedback loops
May process nutrients linked to hormone pathways

These inherited traits may shape how your body functions, even if your lab results look similar to someone else’s.

You and a friend might both show high estrogen on a blood panel, but if your gene variants may affect the speed at which estrogen is degraded(such as variations in CYP1B1 or COMT), your body may retain more of the active hormone, potentially contributing to symptoms the other person doesn’t experience.

That same imbalance can appear in other ways: maybe your partner thrives on fasting, but it leaves you feeling depleted. Your sibling may respond well to hormone therapy, while you struggle with side effects.

Some research suggests that the reasons for high or low hormone levels like testosterone, LH, FSH, and SHBG may have high heritability, in some cases, up to 80%, highlighting the strong genetic influence on hormone patterns.

These patterns may be influenced by genes involved in estrogen or testosterone pathways, insights that aren’t always factored into conventional care plans.

How Genetic Testing Helps Decode Hormone Health

Blood tests offer a snapshot. They tell you what your hormone levels are at a specific moment, but it may be difficult to explain why those levels vary, or why treatments work well for some and not for others.

That’s where genetic testing can offer deeper insight.

Instead of focusing on day-to-day fluctuations, genetic testing looks at your genetic code, which affects how your body may be predisposed to produce, metabolize, or respond to hormones over time.

It can help uncover patterns such as:

Tendencies toward higher estrogen activity due to slower detox pathways
Variants in enzymes that can impact progesterone, cortisol, or insulin balance
Differences in inflammation or nutrient metabolism that affect hormonal feedback loops
Factors that may help explain varied responses to hormone therapy

Unlike hormone panels, which shift based on stress, cycle phase, or time of day, genetic insights remain consistent.

They offer a clearer understanding of how your biology may shape your hormone experience, and where more personalized support might help.

7 Gene-Backed Strategies to Rebalance Your Hormones Based on Your DNA

From estrogen detox to testosterone signaling, these seven strategies based on gene variants just might explain what your bloodwork and lifestyle changes have missed.

1. Know Your Estrogen Sensitivity

Gene: ESR2 (Estrogen Receptor Beta)

Pathway: Hormone Regulation

The ESR2 gene codes for estrogen receptor beta, one of two main receptors that allow your cells to respond to estrogen. While estrogen receptor alpha (ERα) is more prominent in reproductive tissues, ERβ is expressed in areas like the brain, cardiovascular system, bones, and fat.

Genetic variations in ESR2 may influence how your body responds to estrogen signals.

Some variants are linked to lower receptor sensitivity, meaning estrogen is still produced, but the cellular response may be reduced.

Others may be associated with increased responsiveness, potentially affecting how the body reacts to both natural estrogen and environmental estrogens such as BPA or parabens.

These genetic differences can play a role in:

Symptoms often associated with higher estrogen activity (e.g., mood changes, irregular cycles, or fluid retention)
How well you respond to hormone therapy
Risk profiles for estrogen-related conditions, including fibroids, PCOS, or prostate challenges in men
Some research shows that variants in the ESR2 gene may be associated with migraine headaches

Personalized Approaches:

Include cruciferous vegetables (like broccoli, Brussels sprouts, and kale) to support estrogen metabolism via complementary genes like COMT and CYP1B1
Reduce exposure to endocrine-disrupting chemicals by avoiding BPA-lined cans, plastic containers, and synthetic fragrances
Foods like soy or flax, which are rich in phytoestrogens, may interact differently depending on your estrogen sensitivity; some individuals benefit, others may need to monitor their intake
Supporting methylation and liver detox pathways (especially with MTHFR or GSTM1 variants) may help promote healthy estrogen clearance

Supporting methylation and liver detox pathways (especially with MTHFR or GSTM1 variants) may help promote healthy estrogen clearance

2. Understand Your Testosterone Potential

Key Genes: SRD5A1, SHBG, UGT2B17

Pathway: Testosterone Metabolism & Signaling

Testosterone isn’t just about how much your body produces; it’s also about how efficiently it’s activated, transported, and cleared. Variations in several genes can influence these processes and how your body responds over time.

SRD5A1 helps convert testosterone into DHT, a more biologically active form of the hormone. Certain genetic variants may affect the rate of this conversion, which can impact how your body regulates energy, strength, and other androgen-related traits.
UGT2B17 supports testosterone clearance through the liver. Some people may have variants that slow this clearance, potentially increasing circulating testosterone. Others may clear it more rapidly, which could contribute to lower active levels under specific conditions.
SHBG helps regulate how much testosterone remains free and available to the body’s tissues. (See Strategy 3 for more on SHBG’s broader hormone impact.)

Personalized Approaches:

Individuals with testosterone-related gene variations may respond differently to training styles. Some may thrive on high-volume strength routines, while others benefit from lower-rep, power-focused workouts, depending on recovery and hormonal feedback.
Nutrients like zinc and magnesium are important for enzymes involved in testosterone metabolism. A practitioner may recommend optimizing these through diet or supplementation based on your genetic profile.
For some people, managing refined carbohydrate intake may help support insulin regulation, an important hormonal input for testosterone production.

Prioritize sleep and circadian rhythm support: testosterone levels are sensitive to sleep quality, and some genetic variants may increase vulnerability to disruption.

3. Fine-Tune SHBG for Better Hormone Balance

Gene: SHBG

Pathway: Hormone Transport & Availability

SHBG (Sex Hormone Binding Globulin) helps regulate how much of your estrogen and testosterone remains bioavailable. Produced by the liver, SHBG binds to sex hormones in the bloodstream, controlling how much is free to act on cells versus held in reserve.

Genetic variations in the SHBG gene may affect baseline SHBG levels, which can influence hormone signaling throughout the body.

What Your Genes May Influence:

Higher SHBG levels may reduce the amount of free, active hormones, which could be linked to low energy, reduced exercise recovery, or decreased libido in some individuals
Lower SHBG levels may increase free hormone availability, which could affect things like mood, skin health, or menstrual cycle sensitivity

Personalized Approaches:

Supporting stable blood sugar through balanced meals and complex carbs may help promote healthier SHBG levels, particularly for those with a genetic tendency toward lower production
Physical activity affects SHBG differently depending on your genetic makeup. Some individuals may benefit more from aerobic movement, while others respond better to strength-focused routines
Since SHBG is made in the liver, liver-supportive foods like leafy greens and beets, and limiting alcohol or processed fats, may be especially beneficial
SHBG also plays a key role in regulating estrogen, not just testosterone, which makes its influence broader than most people realize

4. Genetic Variations That Influence Estrogen Detox Pathways

Genes: CYP1B1, CYP19A1

Pathway: Estrogen Metabolism

Your body continuously metabolizes and eliminates estrogen through detoxification pathways in the liver. This helps maintain hormonal balance and prevents the buildup of intermediate compounds that could affect how estrogen functions in the body.

Two genes, CYP1B1 and CYP19A1, play important roles in this process:

CYP1B1 is involved in Phase I liver detox and helps convert estrogen into metabolites. Certain variants may increase the production of 4-hydroxy estrogen, a compound that can promote inflammation or tissue sensitivity in some individuals.
CYP19A1 codes for aromatase, the enzyme that converts testosterone into estrogen. Some variants may be linked to increased aromatase activity, which could influence estrogen levels depending on your broader hormonal profile and environment.

Personalized Approaches:

Cruciferous vegetables like broccoli sprouts are rich in sulforaphane, a compound that may support Phase II detoxification and the clearance of estrogen metabolites
Minimizing exposure to endocrine-disrupting chemicals (e.g., parabens, phthalates, BPA) may be especially helpful for individuals with estrogen metabolism variants
Glycine-rich foods such as legumes, spinach, and bone broth support conjugation pathways in the liver, which assist in estrogen elimination
Some individuals also explore lifestyle modifications, like water filtration or reducing pesticide exposure, to further support hormone metabolism

Genetic testing can provide insight into how efficiently your body may process and clear estrogen, offering context that standard hormone panels may not reveal.

5. Cool the Inflammation That Disrupts Hormone Signals

Genes: IL6R, TNFA

Pathway: Inflammation

Chronic, low-grade inflammation can influence how your body produces and responds to hormones like estrogen, testosterone, insulin, and cortisol. Two genes, IL6R and TNFA, are involved in regulating inflammatory signals that may play a role in hormonal balance.

IL6R codes for the receptor that interacts with interleukin-6 (IL-6), a pro-inflammatory cytokine. Certain variants are associated with higher IL-6 activity, which has been linked to reduced hormonal sensitivity and slower recovery in some individuals.
TNFA influences the expression of tumor necrosis factor-alpha, another inflammatory messenger. Genetic variants may contribute to a stronger baseline inflammatory response, which could affect hormonal signaling over time.

Personalized Approaches:

Omega-3 fatty acids like EPA and DHA may help support a healthy inflammatory response, particularly in individuals with IL6R or TNFA variants
Anti-inflammatory herbs like turmeric and ginger may offer additional support, though individual needs can vary and are best assessed with a practitioner
Some people explore how foods like gluten or dairy impact their inflammation, especially when their broader genetic profile suggests heightened sensitivity
Individuals with pro-inflammatory variants may benefit from balancing intense workouts with adequate recovery time to help reduce systemic stress

Genetic insights into inflammation may help explain why some individuals experience fatigue, low resilience, or hormone-related symptoms even when following a healthy lifestyle.

6. Understanding Genetic Variations in Methylation and Hormone Synthesis

Genes: MTHFR, BHMT

Pathway: Methylation

Methylation is a core biological process that helps regulate hormone synthesis, neurotransmitter balance, detoxification, and gene expression. It works by donating methyl groups, small chemical tags, to DNA and other molecules, allowing critical cellular processes to run smoothly.

Some genetic variations can influence how efficiently this process functions.

MTHFR helps convert dietary folate into its active form, 5-MTHF, which supports methyl group production. Common variants like C677T may reduce enzyme activity and increase the need for active forms of B vitamins under certain conditions.
BHMT plays a backup role in methylation through the betaine pathway. When paired with low choline intake, variations in this gene may further reduce methylation support.

Personalized Approaches:

Leafy greens, lentils, and asparagus provide naturally occurring folate, which may be especially important for individuals with MTHFR variants
Some people may benefit from methylated B vitamins like methylfolate or methylcobalamin, though supplement decisions should be guided by a healthcare professional
Foods rich in choline, like eggs, liver, and quinoa, help support the BHMT pathway, particularly when genetic variations are present
Elevated homocysteine levels may indicate challenges in the methylation cycle; genetic testing and follow-up are best done in collaboration with a practitioner

Supporting your methylation pathways can help maintain the systems your body depends on daily, including those related to hormones, energy, and mental well-being.

7. Stabilize Blood Sugar to Protect Hormone Balance

Genes: TCF7L2, IRS1

Pathway: Insulin & Glucose Regulation

Blood sugar regulation plays a central role in hormonal balance, with ripple effects across insulin, cortisol, estrogen, and testosterone pathways.

While nutrition and lifestyle have a big impact, your genes can influence how well your body maintains glucose stability.

TCF7L2 is one of the most studied genes related to glucose metabolism. Certain variants have been associated with reduced insulin secretion and a higher likelihood of insulin resistance over time.
IRS1 supports how insulin binds to and signals within cells. Variants in this gene may reduce insulin signaling efficiency, which can make it harder for glucose to enter cells and be used effectively.

Personalized Approaches:

Meals rich in non-starchy vegetables, legumes, lean proteins, and healthy fats may help support blood sugar balance, which, in turn, supports broader hormone stability
Some people respond better to carbohydrates earlier in the day or after physical activity, depending on how their genes influence insulin sensitivity
A short walk after meals may help regulate glucose levels, particularly for individuals with gene variants that affect post-meal insulin response
While intermittent fasting works well for many, certain genetic profiles may benefit from steady, consistent eating patterns to avoid dips in blood sugar that could disrupt hormonal balance

These genetic insights help explain why one person thrives on a particular eating plan while another struggles, even when both are eating “clean.” Knowing your genetic tendencies allows for more personalized, sustainable blood sugar support.

What to Do If Your Genetic Test Flags a Hormonal Hotspot

Genetic reports can feel overwhelming at first, especially when they include variants related to hormones, metabolism, or detox.

But these insights aren’t a diagnosis. They highlight where your body may function a little differently, and where more support might be helpful.

Here’s how to approach your results with confidence:

Look at the bigger picture: A single gene rarely acts alone. Instead of focusing on one variation, explore how multiple genes in biological pathways, like detoxification, receptor sensitivity, methylation, inflammation, and insulin regulation, may be interacting
Compare genetics with symptoms and lab markers: If your report highlights genes related to estrogen detox but you don’t experience symptoms like PMS or bloating, it may not be a current priority. But if those issues are present, the pathway likely deserves more attention
Support your environment: Genetics set the foundation, but lifestyle determines expression. Nutrition, movement, stress, sleep, and exposure to chemicals all influence how your genes behave
Prioritize support where needed most: If your results show lower efficiency in both methylation and detox pathways, that could be a cue to focus on nutrients like B vitamins, choline, or cruciferous vegetables, ideally with guidance from a professional

FAQs

Can genetic testing identify a predisposition to hormonal imbalances like PCOS or thyroid issues?

Your genetic report highlights genes that influence hormone regulation, detoxification, and receptor activity, factors that may contribute to conditions like PCOS.

For example, variants in CYP1B1 or SHBG can impact estrogen metabolism and hormone availability. While thyroid-specific genes aren’t covered in this panel, the insights still support a broader view of hormonal resilience and vulnerability.

Which genes influence estrogen and testosterone pathways?

Several key genes in your report affect how your body processes sex hormones:

CYP1B1 and COMT help break down estrogen during detox.
SHBG controls how much estrogen and testosterone are free versus bound.
SRD5A1 converts testosterone into its more potent form, DHT.
UGT2B17 helps clear excess hormones from circulation.

Understanding your patterns across these genes can help explain symptoms or shifts in hormone levels, even when lab tests appear normal.

How does my genetic profile affect the foods that support hormone balance?

Your genes impact how your body activates nutrients involved in hormone synthesis and clearance. For instance:

MTHFR and BHMT affect methylation, which fuels hormone production and detox.
If these gene variants affect enzyme function, you may benefit from methylated B vitamins, folate-rich vegetables, and choline from eggs or liver.

Gene-guided nutrition lets you tailor your food choices to support the systems most in need.

If I have flagged hormone-related genes, what can I do to stay ahead?

Think in terms of support, not suppression. Your genes help identify where your hormone systems may need more input.

If your report shows low estrogen clearance (e.g., CYP1B1) or elevated inflammation (e.g., IL6R, TNFA), strategies like cruciferous veggies, omega-3s, and sleep optimization may have a stronger impact for you.

The key is targeted action: small, gene-informed shifts in food, movement, and recovery that bring your body back into rhythm.

Can my genes affect how I respond to hormone replacement therapy (HRT)

Yes. Genes like SHBG and UGT2B17 influence how long hormones stay active in the body. For example, a slow-clearing UGT2B17 variant may amplify your response to HRT, while high SHBG might reduce hormone availability altogether. These insights can help guide more personalized dosing and monitoring if you’re considering HRT with your provider.
