The Soy Controversy

“Women consuming the equivalent of two cups of soy milk per day provides the estrogenic equivalent of one birth control pill… men who consumed the equivalent of one cup of soy milk per day had a 50% lower sperm count than men who didn’t eat soy. –Chris Kresser’s Paleo Code

Soy is often touted as a natural source of estrogen, but is it safe to use either for this purpose or as a food?

“About two ounces of soy products per day may be sufficient to ward off hot flashes and other symptoms” of menopause (Wright & Morgenthaler, Natural Hormone Replacement for Women over 45). However, as an estrogen source, it may not be the safest food option.

Soy is present in nearly every packaged and processed food in the U.S, in fact, the average American gets up to 9% of our calories from soybean oil alone. Compare this to about 2 teaspoons per day in China and 9 teaspoons per day in Japan, most of which is fermented soy, which neutralizes the toxins (like trypsin inhibitors that inhibit protein digestion and affect pancreatic function, and phytic acid, which reduces absorption of minerals like calcium, magnesium, copper, iron and zinc) that are present in most of the soy we consume in the U.S. (Chris Kresser’s Paleo Code)

Unfermented soy also increases our requirement for vitamin D and B12 (the opposite of fermented soy which provides these vitamins!), and disrupts endocrine function (potentially causing breast cancer and thyroid problems). Processed unfermented soy often actually contains carcinogens as well. (Chris Kresser’s Paleo Code)

It is not fully known how soy consumption may impact synthetic hormones, and it’s nearly impossible to avoid all soy since it’s in most of the food we consume, but it would be wise for most people to avoid eating the major processed soy foods like tofu, soy milk, and soy protein isolate. Fermented soy still contains estrogens, but is not as disruptive (or potentially carcinogenic) to our natural hormones, and is probably a safe food for most people.

I would generally recommend that people transitioning towards the masculine side of the spectrum avoid soy foods, and for those looking for natural sources of estrogen, there are many safer feminizing herbs and foods out there. For example, “flax contains substances called lignans, which have been shown to have estrogen-like qualities” (Wright & Morgenthaler). A few foods have small amounts of identical-to-human hormones [about 1-2% potency of human hormones] (Wright & Morgenthaler), including:
Rice, apples, date palm, pomegranate (estrone)
French bean seedlings (estradiol)
rice, licorice (estriol)

Estrogen and Blood Clot Risk in Trans Women

Estrogen produced by the body lowers blood concentrations of several clotting factors and speeds the rate at which clots dissolve. Estrogen also suppresses production of a factor which is involved in enlarging the size of a clot, and is also beneficial to cholesterol levels. (This may be why cisgender men are about 18% more likely to develop DVT than cisgender women.)

Administered estrogen, however, actually increases plasma fibrinogen, the activity of coagulation factors, and platelet activity. This explains why estrogen medications increase blood clots (in both transgender women and cisgender women taking birth control or hormone replacement therapy). Oral estrogen also significantly increases “bad” cholesterol in trans women, while decreasing the level of “good” cholesterol, which can lead to clogged arteries, increasing chances of clots.

Highest risk: Combining antiandrogens (like spironolactone) with oral ethinyl estradiol (birth control pills) carries a much higher risk of thrombosis than any other regimen. Trans women taking birth control pills are 20 times more likely to suffer from DVT than the general population. Premarin also carries a higher risk of DVT than injectable estrogen, though not as high as birth control. This is most often the case for hormones that are procured without a prescription. Prescribed HRT for trans women in the U.S. usually includes spironolactone and 17-beta estradiol (aka micronized estradiol), rather than ethinyl estradiol. This regimen is much less likely to produce clots.

Other risk factors: lack of exercise, long periods of immobility (such as long airline flights), genetic clotting risk, injuries (broken bones especially), liver stress (support liver while taking hormones!), high blood pressure, type 1 diabetes. Aspirin therapy is often recommended if over age 40 because of increased plasma concentrations of coagulation factors. Smoking increases factor XIII, thrombin, and fibrinogen, which increase clotting risk. Smokeless nicotine does not carry the same risk, and abstention from smoking for a period of only 2 weeks significantly decreases the rate of fibrinogen synthesis. Risk is highest within the first year of estrogen use, potentially because oral estrogen is more common than injectable estrogen during this time.

Recommendations:

  • Using injectable rather than oral estrogen of any kind (if using oral estrogen make sure it’s 17-B estradiol)
  • Taking baby aspirin for the first year of HRT if over age 40
  • Supporting your liver metabolism
  • Exercise regularly
  • Quit smoking (or switch to smokeless tobacco for at least the first year of HRT)
  • Test for genetic clotting risk
  • Check blood pressure regularly and maintain safe levels

Symptoms of DVT: inexplicably warm area on your lower leg which persists for more than an hour, localized swelling, redness, pain, shortness of breath, chest pain, symptoms of stroke. CALL 911!

Herbs for Transitioning: Feminizing Herbs

This is a follow-up post to “The Basics.” Also see the transmasculine post here.

For gender affirming transition, herbs can be used alone to create very mild ‘energetic’ effects or to support the body to counteract any side effects of synthetic hormones. Note: Most herbs are unlikely to have a significant effect without any other transition methods. If you are looking for physical effects, prescription hormones are the safest way to make that happen. The dosages you would need to take of herbs in order to get a physical effect can be dangerous.

DO NOT take herbs without consulting with an herbalist to ensure they are safe for you. DO NOT combine herbs with your medications without discussing with a healthcare provider.

Vitex: The Regulating Herb:

Vitex (Vitex agnus) is a hormone normalizer that works with the pituitary gland and increases LH and reduces FSH secretion, which increases progesterone relative to estrogen and testosterone (Wright & Morgenthaler, Natural Hormone Replacement). This helps it regulate emotions, prevent acne, hormonal edema and bloating, and it can help you transition onto and off of synthetic hormones, as well as stabilize fluctuations in hormones while taking hormones.

Estrogenic, Progesterogenic, and Anti-Androgenic Herbs:

  • Rhodeola Rosea is a controversial herb, however, the most informative sources I’ve found say that it increases estrogen levels unless they are already unnaturally high (such as when taking estradiol), in which case it decreases them. Overall this is a strong herb that should be used with caution and medical supervision.
    • If you have had estrogen sensitive breast cancer, bleeding disorders, diabetes, or take acetazolamide, alpha-glucosidase inhibitors, anti-anxiety agents, antibiotics, anticancer agents, antidepressants, anti-inflammatories, antivirals, COMT inhibitors, drugs that affect the cardiovascular system or the immune system, P-glycoprotein-regulated agents, sedatives, theophylline, or stimulants, you should use caution or avoid this herb.
  • Maca is known for its effects of creating curves. It is also known for its aphrodisiac effects, and can increase erectile capacity and sperm counts, which may be a positive or negative thing for you depending on your goals. It also boosts the immune system and helps combat osteoporosis (which can be a side effect of taking spironolactone). Also available in a women’s libido blend.
  • Chaste tree berry/Vitex (Vitex agnus-castus) can increase breast size by stimulating the development of milk ducts. It can therefore have a side effect of causing lactation.
  • Black cohosh/Sheng Ma (Cimicifuga racemosa) contains several compounds in its root (aceteine, formononetin, and triterpenes) that, though not estrogenic themselves, create similar effects to estrogen and can increase breast size. It decreases LH and increases estrogen in relation to progesterone [opposite of Vitex] (Wright & Morgenthaler). Only use this herb under supervision of an herbalist as it is easy to take dangerous amounts.
  • Fenugreek/Hu Lu Ba (Trigonella foenum-graecum) seeds contain a compound (diosgenin) that promotes breast tissue growth. Sprouted seeds contain much more diosgenin than the unsprouted seeds, so breast enlargement is more noticeable if you sprout the seeds first. Fennel works in much the same way.
  • Hops have 0.2-20% the potency of estradiol
  • False Unicorn (used during menopause for estrogen replacement)
  • Licorice (somewhat anti-androgenic and mimicks estrogen). Licorice also notably counteracts side effects of spironolactone (the most common anti-androgen used in the U.S.) like low blood pressure, gastic upsets, fatigue, dehydration, and frequent urination.
  • Other herbs with limited research:
    • Pennyroyal (never take the oil internally!)
    • Goats Rue (promotes lactation)
    • Southernwood
    • Red Clover/Hsun Tsao
    • Caraway
    • Partridge Berry
    •  Anise
    • Raspberry Leaf
    • Mugwort/Ai Ye
    • Yarrow (encourages progesterone)
    • Cramp bark (mildly estrogenic)
    • Turmeric (mildly estrogenic)
    • Alfalfa
    • Burdock
    • Evening Primrose
    • Pau D’Arco
  • Blends:
    • Phytoestrogen Herbal from Vitanica
    • My Evanesce has several herbal blends, most of which have many unnecessary added ingredients, but their Feminol product has a more useful blend of dong quai, black cohosh, chaste tree, white kwao krua, fennel, fenugreek, licorice, kudzu, sarsaparilla, boron, plus b6, d3, and b12. They recommend taking all of their formulations at once which is not only completely unnecessary as they mostly contain the same ingredients but also could lead to dangerous dosages of the herbs. Do not do this and do your own research!
    • “HRT Companion” formula (formulated for side effects of synthetic hormones)
  • Foods:
    • pomegranates
    • legumes
    • yams

Note: DON’T combine synthetic hormones with St. John’s wort/Guan Ye Lian Qiao, it changes the way that medications are metabolized. It also encourages bleeding, so avoid before surgery too!

Herbs for Transitioning: The Basics

This is a follow-up post to “The Basics.” Also see the transmasculine post here, and the feminizing herbs post hereFor information on estrogen and progesterone supportive herbs, check out my follow-up article on Feminizing Herbs

For gender affirming transition, herbs can be used alone to create very mild ‘energetic’ effects or to support the body to counteract any side effects of synthetic hormones. Note: Most herbs are unlikely to have a significant effect without any other transition methods. If you are looking for physical effects, prescription hormones are the safest way to make that happen. The dosages you would need to take of herbs in order to get a physical effect can be dangerous.

DO NOT take herbs without consulting with an herbalist to ensure they are safe for you. DO NOT combine herbs with your medications without discussing with a healthcare provider.

The Basics:

It’s first important to take care of your body with proper nutrition so that you can handle the changes  and stress that will accompany transitioning. All hormones are made of fat, so it’s important to eat good fats (raw oils & omega 3s especially) to help your body form and transform those hormones, and also to coat your nerve cells (their myelin sheaths are also made of fat) to help you cope with stress and stay emotionally healthy. Fats form the boundaries of our cells–they keep out and let in what we want to–we need good fats in our bodies to have good boundaries physically and emotionally!

We ALL have the same hormones, just in different amounts and we USE different amounts of them too. Furthermore, we can change how our bodies use the hormones we already have. Every body makes progesterone from cholesterol, and that progesterone can turn into estrogen OR testosterone. The estrogen and testosterone in our bodies can also convert back and forth (estrogen to testosterone and vice versa). This is the reason you want to get your hormone dosages right: if you take too much, your body is just going to convert it into another hormone to maintain balance in your system. This could actually counter the desired effects of the hormone you are taking: too much estrogen in your system and your body will start converting it to testosterone, counteracting the changes you want to make.

Coming up with a plan for your body:

There are many different options for transitioning, even when just using synthetic hormones. Progesterone itself helps to build tissue and can often be useful for developing breasts (taken externally) or muscle tissue (taken internally). Aromatase is what turns testosterone into estrogen, so you can take extra aromatase instead of (or in addition to) taking estrogen. Likewise, you can take aromatase inhibitor to prevent that testosterone from turning into estrogen, instead of taking testosterone. There are many options for prescription hormones; it’s important to talk to your doctor about what will work best for your body.
For most people, herbs aren’t going to change your hormones drastically alone, so you might choose to start out taking synthetic hormones and, once you’ve achieved the effect you want, use herbs to lower your dose of synthetic hormones or switch to herbs entirely. Herbs can maintain the hormone levels and characteristics you’ve built up with synthetic hormones. This is a good alternative to the sometimes health damaging side effects of long-term synthetic hormone use.
