The Truth About Hormones & Your Sex Drive

Which of these best describes your sex drive?

Want it, need it, gotta have it!

Could take it or leave it...” or

Don’t even think about it!

Whatever you answer, there’s no shame.

Women are pretty reluctant to say our libido (or lack thereof) is one of our top health concerns. But when I dig deep with the women I work one-on-one with in my clinic, I find that almost all of them are struggling with their sex drive.

And personally, when I was struggling with hormone imbalance, my sex drive was non-existent. I thought it was just “normal.” After all, as women we are conditioned to believe we should want sex less than men.

Truth: healthy women have robust sex drives!

Our libido isn’t just dictated by whether our partner brings home flowers or we’ve shaved our legs - it is controlled by a complex group of hormones and neurotransmitters. Too much or too little of one or another can cause our sex drive to dwindle away or get out of hand.

That means that if your libido is lacking, you don’t just need to try lighting candles or new lingerie (although if your sex drive is healthy, that would sound fun instead of like a chore!). Balancing your hormones can restore a healthy libido.

Today, I want to explain how your hormones impact your sex drive. I hope this information empowers you - and if you have more questions or need more support, please reach out to me!


What This Article Can’t Do

Before I dig in to all the juicy hormone info, there are a couple other things I want to get out in the open.

First, most of the research on hormones has been done based on cisgender, heterosexual people and in heterosexual relationships. More research on hormones in other populations is long overdue. If you’re outside this group, some of this information will apply to you and some of it won’t - but I’d love to support you in overcoming hormone issues one-on-one until more inclusive research is available.

Secondly - as you're reading this I know symptoms of too much or too little of various hormones are going to jump out at you. But know this: the only way to diagnose hormone imbalances is with proper testing! That means blood, saliva, and/or urine testing.

Treatment for hormone imbalance is highly individualized, and I always recommend anyone who suspects hormone imbalance work one-on-one with a trained practitioner like myself for accurate testing and treatment! At the end of the article, I’ll share about my favorite hormone tests.

OK - disclaimers done - let’s get to the good stuff!


Estrogen - “The Feminine Hormone”

Estrogen is the hormone we associate with women. It makes women softer - both emotionally and physically. Estrogen is responsible for women’s curves: breasts, hips, and more fat on the butt! In studies of heterosexual men, women with higher estrogen levels were rated as more attractive.

It also increases a woman’s receptive sex drive—the part that makes her interested and open to penetration. Estrogen says “Take me now!”  Women with higher estrogen levels may have more of a seductive sex drive - they are more likely to be receptive to sex, more likely to flirt and give “I’m available” signals,  than they are likely to initiate it.


Testosterone  - “The Masculine Hormone”

What hormone causes horniness? Testosterone is the hormone associated with men - but healthy women have testosterone, too. It helps us build muscle and causes us to feel more competitive and aggressive. In the bedroom, testosterone makes us want to initiate sex and governs the drive for genital sex and orgasms. Women with higher testosterone levels tend to have more of an aggressive sex drive and are more likely to initiate sex than wait for a partner to start things up.  Interestingly, some post menopausal women have relatively higher testosterone levels (as compared to other hormones like estrogen) and may notice more of an interest in initiating at this phase in their lives.

Testosterone makes us less interested in relationships and commitment and more likely to want time alone (that’s what the Man Cave is for!). Women with higher testosterone levels tend to masturbate more, too. Too much testosterone can make us feel irritable - but too little can make us feel depressed.


Dopamine  - “The Pleasure Chemical”

Dopamine isn’t exactly a hormone - it’s actually a neurotransmitter. Dopamine helps us anticipate pleasure - therefore having the drive and motivation to take action. It’s dopamine that makes us anticipate that sex = pleasure.

People who are low in dopamine tend to seem “flat” - they lack interest, enthusiasm, and get-up-and-go.

Testosterone increases the activity of dopamine in our brains, so supplementing with testosterone is often prescribed for women with low libido. But in my experience, this rarely works - or at least not without other support - probably because the issue isn’t just low testosterone, but also low dopamine. (Just another reason why you have to test!)


DHEA  - “The Master Hormone”

DHEA is our most abundant circulating hormone. It’s produced both in the Adrenal glands and in the brain, and most of our other hormones are derived from it. DHEA levels peak in our 20s and start to decline from there - faster for some than others based on factors like your genetics and stress. Oral contraceptives are also know to lower DHEA levels.

Ideally, I like to see DHEA levels on the higher end of the normal range because DHEA can:

  • Lower risk of depression
  • Provide better function in old age
  • Protect against immune suppression when cortisol levels are high (from stress)
  • Prevent osteoporosis
  • Maintain muscle mass

And of course, DHEA plays a major role in sex drive, orgasms, and sex appeal. Higher levels of DHEA in women correlated with higher rates of sexual desirability in studies. Most of our pheromones are derived from DHEA - scents that in the animal world dictate attraction and mating. Pheromones are often what make us feel an “instant connection” or drawn to someone. When a woman complains of low libido, I always test her DHEA levels first!

In times of stress, DHEA levels decrease significantly -and this can cause a cascade of low hormones throughout your body, since most other hormones are derived from DHEA.


Oxytocin  - “The Love Molecule”

Oxytocin is a molecule that is triggered by physical touch. Oxytocin levels increase if you hug, hold hands, have sex, hold a baby - and even if you look at a dog! Levels of oxytocin also spike when you’re aroused and when you orgasm - it’s also what causes the uterus to contract during orgasm. If you’re in love, just thinking about the person can make your oxytocin levels go up.

Oxytocin helps you bond and feel love. It’s especially important for maternal bonding, and oxytocin levels rise during breastfeeding. Higher levels of oxytocin both reduce stress and rational thought - making it easier to “fall in love.”


Progesterone  - “The Cock Blocker”

Does progesterone increase libido? In my practice I call progesterone the cock-blocking, (or clam-jamming) hormone. Basically, progesterone stops your sex drive. The effect of progesterone on your sex drive is so powerful, monks used to take the herb Vitex (aka Chaste Tree Berry!) to promote progesterone production and block their sex drive. Progesterone actually numbs the erogenous zones, meaning you’re likely to have dull orgasm with more stimulation - or no orgasm at all.

Many women have high levels of progesterone because they take hormonal contraceptives. The birth control pill contains a synthetic form of progesterone called progestin. Great birth control, right? Just kill your sex drive completely!

Progesterone isn’t all bad though - it promotes maternal behavior and has a mild sedative effect. It can make you feel calm, happy, and that everything is a-okay.

Does ovulation make you horny? In the second half of the menstrual cycle (after ovulation), progesterone is naturally higher. That makes sense biologically - once you’ve ovulated, your body won’t drive you to sex for reproductive reasons. When natural progesterone is balanced with estrogen, the dip in sex drive isn’t as strong and some women don’t notice it at all. Others might just be more interested in cuddling rather than going for an orgasm.


Prolactin  - “The Nursing Hormone”

Prolactin is mostly associated with lactating women - it is the hormone that triggers your milk to let down after birth. Prolactin also tends to lower your sex drive - that’s why, in general, women have less sex when they are breastfeeding. Depending on your estrogen levels, you might retain some “receptive” sex drive even when prolactin is higher.

Promoting dopamine opposes prolactin. So if your prolactin levels are high and you’re NOT breastfeeding, using dopamine-promoting herbs can help lower prolactin and improve your sex drive. The only way to accurately gauge your prolactin levels is with testing!


Serotonin - “The Happy Chemical”

Serotonin is dopamine’s partner - together they are the two main neurotransmitters in the brain. Serotonin can impact your sex drive whether it’s too high or too low. Certain medications (like SSRIs) can cause high levels of serotonin. Dieting and chronically low calories can cause low serotonin, too.

Very high levels of serotonin dull your sex drive. That's why SSRI antidepressants have lowered sex drive and delayed/weaker orgasms as a side effect.

Conversely, low levels of serotonin can magnify your sex drive. In people with depression, low serotonin levels can even lead to sex addiction. In women with low serotonin, orgasms happen faster and easier. Men with low serotonin ejaculate right away.


Your Menstrual Cycle - “The Conductor”

Your menstrual cycle is like the conductor of all these hormones and chemicals. As the cycle progresses, hormone levels naturally rise and fall, leading to a shift in your sex drive.

At the beginning of your cycle, all hormone levels are low. Mid-cycle, estrogen and testosterone both spike - leading to an increase in sex drive (you’ll be both more aggressive and receptive to sex).

Many women also notice their libido peaks right before they start their period, as progesterone is naturally falling relative to testosterone. Your genitals will be more sensitive and it’s easier to orgasm during progesterone withdrawal.

During menses, some women have an increased sex drive - again because progesterone is lower relative to testosterone. But because serotonin levels can also drop during this time you might be grouchy too. Grumpy and horny!

The natural shift in hormones throughout the month can explain why sometimes you want sex more for the cuddling, emotional bonding, and skin-to-skin contact,  - and why other times you just want an orgasm without all the bells and whistles.


Your Hormones & Your Libido

Our sex drive is completely dependent on our hormones. And as you’ve learned in this article, it’s not as simple as “more testosterone makes you horny!” Balanced hormones are the key to a healthy sex drive.

If your sex drive isn’t how you’d like it to be - either too much or too little - looking at your hormone balance is a great place to start. I know you’re sick of hearing me say this by now, but the ONLY way to accurately diagnose hormone imbalance is with advanced testing. You never want to “guess and check” by starting treatments or supplements for what you “think” is the problem. This can cause even greater imbalances that take more time and work to resolve.

Over the years I’ve used blood and saliva hormone tests - but now I almost exclusively use the DUTCH hormone test. This test is a kit your practitioner orders and you complete at home. It uses dried urine (that’s what the D and U stand for in DUTCH) to accurately test various hormone levels. It’s more accurate than saliva testing, and much simpler than blood testing. You just pee on a stick, let it dry, and mail it back to the lab.

Once I know a patient’s hormone levels, we can work together to come up with a plan to balance them. I never share exact protocols publicly because I’ve never had 2 patients who needed the exact same treatment! Hormones really are that unique.

My Top Travel Tips for A Healthy Gut

Traveling is one of my biggest passions. When I got married, we chose to do a destination ceremony and reception with all of our friends and family in Sayulita, Mexico, instead of a traditional wedding (no regrets there!).

Traveling hasn’t always been fun for me, though. When I was younger, I felt like EVERY time I traveled, I got sick. And I’m not talking about a cold, folks - I’m talking about the nemesis of every globetrotter: traveler’s diarrhea.

Traveler’s diarrhea, Montezuma’s revenge, Delhi/Bali belly - it’s all caused by food poisoning. And while it will definitely ruin your trip, it also has a more sinister side - food poisoning can cause lasting damage to your digestive system leading to a lifetime of #gutproblems.

Want to know how food poisoning can cause long-term digestive issues - and what I do to avoid traveler’s diarrhea (even in the most exotic locales!)? Keep reading!

(Not interested in the science? Skip here for my travel tips).


How Food Poisoning Can Wreck Your Gut Long Term

I can’t tell you how many patient in my clinic can trace their digestive symptoms back to a case of food poisoning. And the science backs them up! Food poisoning is a known cause of irritable Bowel Syndrome (IBS). IBS after food poisoning is called “post-infectious IBS.”

But this gets a little complex, so bear with me here...

IBS isn’t a disease - it’s a syndrome. That means it’s just a name for a group of symptoms (fun stuff like gas, bloating, diarrhea, constipation, and food intolerances). IBS is a diagnosis of exclusion, meaning your doctor will call your symptoms IBS when they can’t find any other cause for them.

For many people - perhaps as much as 60% - the actual cause of IBS symptoms is something called Small Intestine Bacterial Overgrowth (SIBO). SIBO occurs when bacteria that should be confined to the large intestine migrates up and into the small intestine. A healthy small intestine should have very little bacteria in it!

So how does bacteria get from the large intestine to the small to cause SIBO?

It’s usually do to a problem with the Migrating Motor Complex (MMC). The MMC is what creates movement in your intestines - called peristalsis - and moves food from your stomach down through your intestines and eventually out of your body.

So what can harm your MMC? The most common causes are chronic viruses like Lyme disease, structural abnormalities, high stress levels,  and… food poisoning!

Stay with me here - food poisoning can cause your Migrating Motor Complex to malfunction. When the MMC malfunctions, bacteria can move from the large to small intestine and overgrow, causing SIBO - and SIBO is the cause for as much as 60% of IBS!

As you can see, it’s a complex chain of events - and that’s why for years doctors have missed the connection between IBS, SIBO, and food poisoning. Luckily they are catching up now.


Toxins & Autoimmune Responses

So how exactly does the food poisoning cause damage to the Migrating Motor Complex?

Common food poisoning bacterias like E. coli, salmonella, Campylobacter jejuni, and Shigella all produce a toxin called cytolethal distending toxin B. It sounds bad, doesn’t it?

Your body will start producing antibodies against the cytolethal distending toxin B. For some people, they’re able to fight it off over in a few days and move on without long-term problems, but for about 10% of us (raising my hand!) we can’t fight it off as quickly - and therefore we keep producing more and more antibodies.

These antibodies don’t just fight the cytolethal distending toxin B - they also reduce a kind of protein in our intestine called vinculin.

Vinculin is very important in the health of Migrating Motor Complex - vinculin is crucial for proper function of nerve cells in the gut that cause peristalsis. When the MMC isn’t functioning and movement of food through the gut is slowed down, bacteria can overgrow and cause SIBO - plus other symptoms like bloating and gas.

The good news is that your gut can recover vinculin over time. First, you need to heal the SIBO. But it’s also critically important that you don’t get food poisoning again. So if you already have some gut issues, don’t stop reading now!


Here’s What I Do To Avoid Traveler’s Diarrhea

The key to avoiding traveler’s diarrhea is being proactive - think about where you’re going, research, and prepare! There are supplements I take to prevent illness, supplements I bring with me for defense in case I start feeling sick, and hygiene practices I follow, too.


Supplements I Use When Traveling To Keep My Gut Happy

When I’m travelling, I always take a probiotic. My favorites are Floramyces (which contains the yeast Saccharomyces boulardii) or UltraFlora Acute Care (this one blends S. boulardii with Bifidobacterium and Lactobacillus). I take 1 capsule of either, 1-2 times daily.

I also take Biocidin Advanced Formula Liquid to help boost my immunity. I start with 3 drops per day and work up to 5-10 drops twice daily.

Finally, I always take an Adaptogen blend. Adaptogens are herbs that help mitigate the stress of traveling. Yes, traveling is fun - but it is also hard on our bodies! Moving through time zones, awkward sleep schedules, and even just enjoying all the “newness” are all registered as stress to our bodies. I like blends that contain herbs like rhodiola for emotional and mental stress and eleuthero for physical stamina.  NanoMojo Liquid and HPA Axis Homeostasis are my two go-tos.


Don’t Eat That!

Hygiene practices are so important for avoiding traveler’s diarrhea.

I always carry hand sanitizer with me - but not the conventional kind! Commercial hand sanitizers are full of BPA and other chemicals. Instead I make my own from aloe vera gel with lavender and tea tree essential oils, plus some Silvercillin. If you don’t want to make your own, this is good alternative. And of course - wash your hands with hot soap and water whenever you can.

Only drink bottled water - and never get ice! (Yes, even on the plane and in fancy restaurants!)

Avoid salad and uncooked veggies - especially lettuce. Cooked veggies (and cooked, hot food in general) are better when traveling. Worried about missing your greens? I bring a greens powder with me and mix it with bottled water. This one is my favorite.

Make sure you wash any produce you buy. As tempting as it is, don’t eat fruit straight from the farmer’s market cart. Wash it with a non-toxic fruit and veggie disinfectant first!

When eating out, look for food carts and restaurants with long line and plenty of locals.


Do This If You Feel Something Coming On

The minute I start to feel “off” - fatigued, grumbling stomach, or even a headache - I switch from my prevention to my treatment protocol.

I up the Biocidin Liquid to 10 drops, 3x per day.

I double up the probiotic.

I add in Oregano Oil Gelcaps for several days  - 2 caps 3x daily.

And if diarrhea strikes? I go to a classic Chinese remedy called Huang Lian Su. It’s a blend of berberine-containing herbs that always works for me. I use 4-5 tablets, 3-4 times daily.

Happy Trails To You!

I hope these suggestions helps ease your fears about traveler’s diarrhea - and allow you to travel the world without getting sick!
