Hormone Optimization
- Hormones have a significant impact on our mood, behavior, and feelings.
- Hormone optimization is a fascinating area of biology that involves understanding and influencing the levels of estrogen and testosterone.
- The process of hormone optimization starts during puberty and continues throughout life.
- Practical tools and strategies can be used to optimize hormone levels and improve overall well-being.
Salutogenesis: A Powerful Way to Conceptualize Health
Salutogenesis is a concept that focuses on promoting well-being and enhancing health through specific behaviors, such as nutrition, exercise, and supplementation. It involves a mindset of doing these behaviors to feel good, improve energy levels, and enhance endocrine and metabolic function. The salutogenic model complements the pathogenic model by considering both moving away from sickness and moving towards health and well-being. It aligns with the wellness community and practices, and exists within the field of allopathic medicine. Studies have shown that recognizing the positive effects of behaviors can have a significant impact on our overall well-being, even at the physiological level.
Estrogen and Testosterone: Sources, Levels & Ratios
Hormone optimization focuses on estrogen and testosterone ratios, which impact well-being, reproduction, and sexual behavior. Optimization methods include behavioral tools, supplementation, and prescription drugs. Steroids encompass more than anabolic steroids, with exercise, cold exposure, and breathing patterns influencing hormone levels. Hormone levels vary between individuals and throughout life, with estrogen increasing during puberty and decreasing during menopause. Testosterone levels increase during puberty and decline gradually with age. Adrenals also produce testosterone in response to competition.
The Power of Competition, Plus: Anxiety, Persistence & Dopamine
Competition has a profound impact on sex steroid hormones, particularly testosterone, which plays a crucial role in determining access to mates and reproduction. Higher testosterone levels are associated with increased access to mates in various species. Testosterone also reduces anxiety, promotes novelty-seeking, and facilitates competitive interactions. Competitive environments can increase testosterone levels, and winning promotes dopamine release, which further increases testosterone. Competing alone also increases testosterone levels. This suggests that competition is an ancient mechanism that encourages competitive behaviors through the feedback of testosterone. The competition for mates affects both males and females, leading to a disparity in access and quality of mates.
Testosterone & Libido Pre-Ovulation
- Testosterone levels in females rise before ovulation, leading to increased reproductive behavior and libido.
- This increase in testosterone prompts female humans to seek out sex more than usual.
- The effect is observed through self-reporting and measurements of testosterone-estrogen ratios.
- Regardless of chromosomal or gonadal background, a single molecule can enhance the desire for mates, willingness to compete, and decrease stress and anxiety.
Estrogen & Sexual Receptivity; Libido In Males
- Increases in testosterone promote seeking of mates and reproduction in both males and females
- Increases in estrogen promote receptivity to mating in females
- Testosterone drives seeking of sex, while estrogen promotes the actual act of sex in females
- Estrogen is important for libido in males
- Low estrogen levels in males lead to loss of libido
- Optimal sexual behavior requires both testosterone and estrogen in both males and females
How Sex Behavior Impacts Testosterone: Observing vs. Actual vs. Abstinence
Sexual behavior can impact testosterone levels in males. The physical act of sex, seeking sex, and orgasm/ejaculation all play a role. Dopamine and testosterone tend to increase together during sexual activity. However, after ejaculation, there is a release of prolactin, which sets a refractory period during which a male cannot have sex again. The duration of this refractory period varies based on the amount and duration of prolactin release.
- Observing sex, such as watching pornography, leads to slight increases in testosterone.
- Participating in sex with a partner results in significant increases in testosterone.
- Ejaculation affects testosterone levels, but the specific impact is not mentioned.
- Sex and ejaculation do not reduce testosterone levels, but they do increase prolactin levels.
- Abstinence or sex without ejaculation for a week or more can increase testosterone levels up to 400%.
- Both sex and abstinence can increase testosterone, but abstinence has a greater effect.
Understanding the nuanced relationship between sex, ejaculation, testosterone, and dopamine is important for understanding how these behaviors impact hormones and vice versa.
Testosterone & Prolactin: Sex Seeking vs Pair Bonding
- Sex increases testosterone and dopamine levels, but also increases prolactin levels.
- After sex, prolactin levels rise, promoting a sense of calm and potentially encouraging pair-bonding.
- This may lead individuals to spend more time together, exchanging smells, hormones, and possibly pheromones.
DHEA (dehydroepiandrosterone): Effects on Levels/Ratios
DHEA, a hormone produced by the adrenals, can increase both testosterone and estrogen levels. The extent to which it increases one or the other depends on the individual's starting hormone levels and the presence of aromatase. Individuals with high aromatase levels may see more estrogen production with DHEA, while those with low testosterone and high estrogen levels may experience mainly estrogen production. DHEA acts as a global promoter of sex steroid hormones, with specific effects varying based on individual factors and the presence of ovaries or testes.
- DHEA can increase both testosterone and estrogen levels.
- The extent of increase depends on starting hormone levels and the presence of aromatase.
- High aromatase levels may lead to more estrogen production with DHEA.
- Low testosterone and high estrogen levels may result in mainly estrogen production.
- DHEA acts as a global promoter of sex steroid hormones.
- Specific effects vary based on individual factors and the presence of ovaries or testes.
Behaviors That Decrease Testosterone (& Cortisol): Parenting & Prolactin
Becoming a parent can significantly decrease testosterone levels in expecting fathers by almost 50%, while cortisol levels drop by three-fold and estradiol levels double. These hormonal changes can lead to weight gain and are primarily caused by an increase in prolactin. Prolactin suppresses sex steroid hormones and increases other categories of hormones. This phenomenon, known as the "dad bod," is not limited to humans but is observed in other species as well. The duration of these hormonal changes depends on the level of contact and exposure to the baby. However, it is not recommended to prioritize maintaining high testosterone levels over parenting responsibilities. These evolutionary mechanisms influence our hormones to bias us towards specific behaviors. Reductions in testosterone promote parenting rather than seeking sex. Increases in prolactin and decreases in cortisol lead to a shift towards parenting behavior and away from reproductive behavior in both sexes.
How Illness Impacts Testosterone & Estrogen: Cytokines, e.g., IL-6
Illness can impact testosterone and estrogen levels in the body. When we are sick, our desire for sex decreases, and this can be explained by the release of inflammatory cytokines, such as IL-6. IL-6 reduces the desire for sex and lowers testosterone and estrogen levels. To optimize hormone levels, it is important to keep IL-6 levels low. IL-6 can interact with receptors for estrogen and testosterone, preventing these hormones from having their desired effects. Inflammatory cytokines like IL-6 are detrimental to sex steroid hormones, while anti-inflammatory cytokines like IL-10 can support them.
How Exactly Do Behaviors Change Hormones?
Behaviors can modulate sex steroid hormones, such as testosterone and estradiol, through mechanisms involving smell and possibly pheromones. Hormones are chemicals that impact tissues and cells, while pheromones are chemicals released that can affect hormone levels.
Key points:
- Behaviors can change hormone levels
- Sex steroid hormones like testosterone and estradiol can be modulated by behaviors
- Smell and pheromones play a role in this modulation
- Hormones are chemicals that impact tissues and cells
- Pheromones are chemicals released that can affect hormone levels.
Pheromones: Miscarriage, Menstrual Cycles, Puberty Onset, & Mate Recognition
Pheromones are chemical signals that impact members of the same or different species. While controversial in humans, pheromone effects are well-established in animals. Key points include:
- Lee-Boot effect: Change in ovulation cycle when females are housed without males.
- Bruce effect: Spontaneous abortion of a fetus when a novel male is introduced.
- Pheromones play a role in miscarriages, puberty onset, and menstrual cycle synchronization.
- Vandenbergh effect: Acceleration of puberty in females when exposed to sexually competent males.
- Synchronization of menstrual cycles through sweat collected from females.
- Pheromones modulate menstrual cycle patterns, changing duration and ovulation pattern.
- Lack of a well-identified pheromone organ in humans.
- Pheromones play a significant role in mate recognition and attraction.
- Perfume manufacturers incorporate chemical compounds to attract mates.
- Pheromones impact hormone levels and the formation of memories.
- Pheromones have a profound influence on mate selection and reproductive behaviors.
Apnea: A Powerful Bi-Directional Influence On Estrogen & Testosterone
Apnea, the interruption of breathing during sleep, has a powerful bi-directional influence on estrogen and testosterone levels. Reductions in estrogen or testosterone may cause apnea, as estrogen receptors are found on neurons that innervate the lungs and testosterone receptors are found on lung cells. However, regardless of directionality, optimizing breathing patterns during sleep and waking hours can improve hormone levels. Breathing techniques like the physiological sigh can reduce apnea episodes and enhance sleep quality, while specific techniques while awake can also optimize hormone levels.
Mouth vs. Nose Breathing & Hormone Levels: Effects Via Sleep and Direct Effects
Breathing through the nose, rather than the mouth, has numerous benefits. It improves the cosmetic features of the jaw and face, as well as promotes better gas exchange and modifies neurotransmitter levels. Mouth-breathing, especially in children, can lead to unattractive changes in facial structure. Nasal breathing during wakefulness and sleep positively impacts hormone levels, specifically testosterone and estrogen. This is achieved by improving sleep quality, which in turn supports the production of appropriate levels of these hormones.
- Proper breathing, specifically through the nose, is crucial for optimizing hormone levels, including testosterone and estrogen.
- Breathing properly ensures deep sleep and prevents apnea, which negatively affects hormone production.
- Studies have shown that reducing or eliminating apnea leads to significant increases in testosterone in males and proper estrogen to testosterone ratios in females.
- Therefore, proper breathing is an important tool for hormone optimization.
How Sleep Adjusts Cortisol/Testosterone and Cortisol/Estrogen Ratios
- Proper sleep is important for maintaining healthy levels of testosterone and estrogen
- Sleep helps to adjust hormone levels by reducing cortisol, a stress hormone that can interfere with testosterone and estrogen production
- Cortisol competes with cholesterol, which can be converted into testosterone or estrogen, and high levels of cortisol can inhibit this conversion
- Breathing through the nose during waking hours and during sleep can help optimize hormone levels by increasing oxygen intake and reducing carbon dioxide buildup
- For individuals with severe sleep apnea, a CPAP machine may be necessary
- Some people are using mouth taping as a less extreme alternative to a CPAP machine
- Taping the mouth shut during sleep can help shift from mouth-breathing to nose-breathing, which is beneficial
- Dilation of the nasal passages during the day can improve nasal breathing.
02:CO2 Ratios, Nasal Breathing During Exercise
Nasal breathing during exercise is recommended for optimal performance, especially in cardiovascular exercise. The sinuses can dilate over time, making nasal breathing easier and leading to increased output. However, there are exceptions for certain sports or activities that may require mouth breathing. Overall, nasal breathing is beneficial for most recreational athletes and exercisers.
Key points:
- Nasal breathing during exercise can reduce cortisol levels and prevent apnea.
- It can indirectly increase testosterone and estrogen levels.
- Nasal breathing is a zero-cost and effective method to improve lung capacity and dilate sinuses.
- It can also have cosmetic benefits.
- Paying attention to the viewing of light is another behavioral advice.
Light Viewing Patterns & Hormones: Dopamine, GnRH
- Viewing bright light, especially within the first hour of waking, has significant effects on sleep, wakefulness, hormone levels, fertility, libido, and healing.
- The relationship between light, dopamine, and hormones is strong, and light-viewing behavior directly impacts hormone levels.
- The scientific literature on this topic is extensive and spans several decades.
- Understanding the powerful effects of light on sex steroid hormones is crucial for optimizing hormone levels and overall well-being.
Spring Fever: Tyrosinase, Hair Color, Mating Frequency
The most profound aspect of the topic is the relationship between light exposure, neurotransmitters, hormones, and breeding behavior in animals.
Key points:
- Certain animals change fur color and exhibit changes in breeding patterns with the seasons.
- Dopamine, a neurotransmitter, plays a role in fur color and breeding behavior.
- Dopamine levels are influenced by the amino acid tyrosine, which is involved in melanin production for hair and skin pigmentation.
- In the summer months, animals breed more and have increased pigmentation due to longer days.
- In the winter months, animals breed less and have decreased pigmentation due to shorter days.
- Humans may also experience an elevation in mood during the spring and summer months.
- Increased sunlight exposure in spring leads to higher dopamine levels, stimulating melanin production and affecting pigmentation in skin and hair.
- Higher dopamine levels also lead to increased testosterone and estrogen levels, enhancing reproductive behavior, well-being, social interactions, and reducing anxiety.
- Proper light exposure in the early part of the day promotes testosterone and estrogen production, while avoiding bright light exposure at night is crucial for maintaining healthy levels.
- Sleep deprivation and excessive light exposure at night can suppress dopamine release and reduce testosterone and estrogen levels.
- Prioritizing proper breathing and light-viewing behavior is important for optimizing hormone levels.
- Tools can be helpful for individuals seeking to regulate their estrogen or testosterone levels.
Specificity of Hormone Effects
The specificity of hormone effects is discussed in this video. Bright light exposure early in the day can impact sex steroid hormone levels, specifically testosterone and estrogen. The effects vary based on an individual's chromosomal and gonadal background. For those with higher estrogen levels, bright light increases estrogen and slightly raises testosterone. For those with higher testosterone levels, bright light increases both testosterone and estrogen while maintaining their ratio. The aim is to optimize an individual's existing hormone ratios.
Temperature: Cold & Hot Gonads
The profound aspect of the text is that heat and cold can have profound influences on hormone levels, including testosterone and estrogen.
Key points:
- Temperature and day length are linked, with warmer temperatures and longer days in the summer leading to higher hormone levels, while colder temperatures and shorter days in the winter result in lower hormone levels.
- Cold exposure, such as ice baths, cold showers, and wearing ice pack underwear, can have positive effects on testosterone and estrogen levels.
- Cold exposure stimulates the release of gonadotropin-releasing hormone (GnRH), which in turn stimulates the production of testosterone and estrogen.
- Cooling neurons can shut down the vascular system, leading to reduced blood flow and hormone entry into the gonads. When the gonads heat up again, there is a rebound effect of increased blood flow and hormone release.
- There is no scientific evidence to support the idea that conceiving a child at a specific room temperature can determine their gender.
- Excessively high heat is detrimental to testes, sperm production, and sperm health. Heat's impact on fertility may be separate from its role in promoting estrogen or testosterone.
How To Exercise: Types, Effort Level, Sequencing
Exercise and Testosterone: Types, Effort Level, and Sequencing
- Heavy-resistance exercise, specifically weight training with heavy loads, leads to the greatest increases in testosterone.
- Working at 70% to 95% of maximum effort or even going down to one-repetition maximum recruits high-threshold motor units and activates more neurons to recruit more muscle fibers.
- Weight training to failure does not have the same effect on testosterone levels.
- Engaging neurons that recruit high-threshold motor units in muscle, without going to failure, can stimulate the production of testosterone.
- Working too hard and increasing cortisol levels may reduce testosterone.
- The mechanistic details of how exercise influences testosterone levels are still not fully understood.
- Weight training with heavy loads but not to failure is the best-supported method for increasing testosterone.
Cardio/Endurance vs. Resistance Training (First or Last?) Yes, It Matters
Endurance activity performed before weight training leads to decreases in testosterone levels during the weight training session. To optimize testosterone levels, it is recommended to do weight training first and cardio-type endurance activity afterward. High-intensity interval training increases testosterone, while endurance exercise beyond 75 minutes can lead to reductions in testosterone, likely due to increases in cortisol. Limiting endurance exercise to 75 minutes or less and keeping intensity moderate can help prevent cortisol levels from skyrocketing. Testosterone therapy is sometimes used to maintain optimal testosterone levels.
- Endurance activity before weight training decreases testosterone levels during weight training
- Weight training should be done before cardio/endurance activity to optimize testosterone levels
- High-intensity interval training increases testosterone levels
- Endurance exercise beyond 75 minutes can lead to reductions in testosterone due to increases in cortisol
- Limiting endurance exercise to 75 minutes or less and keeping intensity moderate can prevent cortisol levels from increasing too much
- Testosterone therapy is used to maintain optimal testosterone levels
Estrogen & Menopause: Compounds That May Ameliorate/Reverse Symptoms
Menopause is characterized by a reduction in estrogen levels, leading to symptoms such as hot flashes and mood swings. Hormone therapy is a common treatment, but its success varies. Compounds like black cohosh, Panax ginseng, maca, Valeriana officinalis, and Pueraria mirifica have been studied for their effects on menopause symptoms. Black cohosh has a modest effect, Panax ginseng decreases libido-related symptoms, maca increases dopamine levels, Valeriana officinalis improves hot flashes and insomnia, and Pueraria mirifica is comparable to estrogen replacement therapy. However, caution should be exercised due to their potential link to breast cancers.
Nutrients That Optimize The Foundation For Hormones
Certain nutrients, such as vitamin D, zinc, and magnesium, are important for promoting testosterone and estrogen production in the proper ratios. Deficiencies in these nutrients can negatively impact the hypothalamic-pituitary-adrenal axis and sex steroid hormones. However, the optimal levels of these nutrients vary depending on the individual and context. To determine the appropriate dosage, it is recommended to consult examine.com or get blood work done to assess hormone and vitamin D levels.
- Vitamin D, zinc, and magnesium are crucial for hormone production
- Deficiencies in these nutrients can disrupt hormone balance
- Optimal levels vary for each person
- Consult examine.com or get blood work done to determine appropriate dosage
Opioids as Severe Hormone Disruptors
Opioids, such as those involved in the opioid epidemic, significantly reduce levels of testosterone and estrogen by disrupting receptors on gonadotropin-releasing hormone neurons in the hypothalamus. Prolonged use of opioids can lead to various endocrine syndromes, including gynecomastia in males and disruptions to the ovary in females.
Testes, Antlers & Ovaries
The optimization of testosterone and estrogen levels is the main focus of the video. Key points include:
- Vast literature on the topic, including the use of materials like deer antlers and bull testes and the consumption of supplement compounds.
- Testosterone and estrogen have powerful effects and their understanding has led to the development of the birth control pill.
- Creatine has good evidence for its ability to adjust androgens.
Creatine & Increasing DHT (Dihydrotestosterone)
Creatine has the potential to increase DHT (dihydrotestosterone), which plays a role in masculinization and the development of primary sex characteristics. However, the effect of creatine on DHT and hair loss is debated and depends on individual factors such as the amount of 5-alpha reductase and susceptibility to hair loss. Other factors can also affect testosterone levels.
- Creatine has the potential to increase DHT levels.
- DHT has a higher affinity for the androgen receptor than testosterone.
- The effect of creatine on DHT and hair loss is debated.
- Individual factors such as the amount of 5-alpha reductase and susceptibility to hair loss can influence the effect of creatine on DHT.
- Other factors can also affect testosterone levels.
Free and Bound Testosterone: SHBG (Sex Hormone Binding Globulin), Tongat Ali
Testosterone is mostly bound to sex hormone binding globulin (SHBG) or albumin, which are necessary for transporting testosterone into cells and regulating its levels. While optimizing free testosterone is important, binding globulins have specific functions in transporting testosterone to tissues and organs. However, excessive binding of testosterone by SHBG can negatively affect libido and muscle growth. Tongat Ali, a natural supplement, has been shown to have pro-fertility, pro-free testosterone, and subtle aphrodisiac effects. It can also act as a slight anti-estrogen. Tongat Ali has been found to liberate bound testosterone, increasing the availability of free testosterone. However, it may cause excessive alertness and insomnia if taken too late in the day. Further research is encouraged for those interested in increasing free testosterone.
Nettles, Prostate, Boron, & Blood Brain Barrier
Nettles, Prostate, Boron, & Blood Brain Barrier Summary:
Nettles have the potential to increase free testosterone in the blood, but they may also have negative effects on the prostate and liver. Boron, extracted from meteors, has scientific support for freeing up testosterone. However, carrier proteins like albumin and SHBG are important for transporting testosterone into the brain for cognitive effects. The blood-brain barrier relies on carriers to transport molecules, including lipophilic sex steroid hormones. The goal is not to completely free up all testosterone, but to achieve a range that aligns with individual goals. Boron is typically taken in a couple of grams per day without specific side effects.
Key Points:
- Nettles can increase free testosterone but may have negative effects on the prostate and liver.
- Boron, extracted from meteors, has scientific support for freeing up testosterone.
- Carrier proteins like albumin and SHBG are crucial for transporting testosterone into the brain for cognitive effects.
- The blood-brain barrier relies on carriers to transport molecules, including lipophilic sex steroid hormones.

- Boron is typically taken in a couple of grams per day without specific side effects.
Hormone Related Cancers: Sometimes Reducing Estrogen and Testosterone Is Optimal
Hormone-related cancers, such as breast and testicular cancer, are influenced by estrogen and testosterone levels. Tissues with rapid cell reproduction are vulnerable to cancer development. Androgens promote growth in cancers and tissues with high cell turnover. However, brain tissue has low cell turnover and is less prone to cancer. Optimizing estrogen and testosterone levels requires caution, as more hormones are not always better. Modulating hormones, especially androgens and estrogens, can impact cancer development.

- Androgens promote growth in cancers and tissues with high cell turnover.
- Brain tissue has low cell turnover and is less prone to cancer.
- Optimizing estrogen and testosterone levels requires caution.
- Modulating hormones can impact cancer development.
Ecdysteroids: Mimic Mammalian Hormones
Ecdysteroids, molecules found in foods like spinach, mimic mammalian hormones and have bioavailability. A study showed that when combined with strength training, ecdysteroids led to significant increases in muscle mass, strength, and hypertrophy effects. As a result, ecdysteroids should be included in the list of prohibited substances. However, the discussion has not yet addressed substances that directly affect the brain.
Key points:
- Ecdysteroids are molecules found in foods like spinach that mimic mammalian hormones.
- Some ecdysteroids, like turkesterone, have bioavailability and can affect human physiology.
- A study showed that ecdysteroids, when combined with strength training, led to significant increases in muscle mass, strength, and hypertrophy effects.
- Ecdysteroids should be included in the list of prohibited substances.
- The discussion has not yet addressed substances that directly affect the brain.
Optimizing Brain Hormones: Chorionic Gonadatropin, Fadogia Agrestis
Optimizing Brain Hormones: Chorionic Gonadotropin, Fadogia Agrestis
Luteinizing hormone (LH) is a hormone that promotes the release and production of other hormones in the body. Human chorionic gonadotropin (hCG) is a prescription drug that increases LH levels and is used to increase fertility, testosterone, and estrogen. It can be used to enhance sports performance or in cases where hormone production has been disrupted.
Supplements like Fadogia agrestis can increase LH levels, which in turn can increase testosterone and estrogen levels. However, the side effects of Fadogia agrestis are not well-documented, so it is important to get blood work done before taking any supplements or modifying sex steroid hormones. Monitoring hormone levels is crucial to avoid negative impacts on hormone production.
Understanding and monitoring the menstrual cycle in females and testosterone levels in males is important when optimizing sex steroid hormones. It is crucial to be cautious and aware of the delicate feedback loop involved in hormone regulation. Blood draws and tracking ovulation cycles are suggested methods for monitoring hormone levels. Supplements and molecules can also be used in hormone optimization.
Additional Compounds, Liver Toxicity, Overall Milieu
The most profound aspect of the text is the discussion of additional compounds that can optimize testosterone and estrogen levels.
Key points:
- Various compounds have scientific data supporting their effects on testosterone, but most studies have been conducted on rats.
- Some compounds may have liver toxicity similar to anabolic steroids.
- Compounds like magnesium, D3, and zinc are considered "housekeeping" for the production of estrogen and testosterone.
- These compounds create an overall milieu of support for normal hormone levels, rather than significantly increasing them.
- It is important to understand the difference between general support and creating a large increase in hormone levels.
