## Synthesis

**Benign Prostatic Hyperplasia (BPH)** is a noncancerous enlargement of the prostate gland that Ray Peat argued is driven primarily by **estrogen**, not testosterone, in the context of a declining metabolic rate. [Source 1, 3] Peat explained that the conventional view—that testosterone causes prostate growth and estrogen inhibits it—was a logical error derived from an oversimplified model of sex hormones. [Source 11] In aging men, *thyroid deficiency* weakens the liver's ability to detoxify hormones, causing testosterone to be converted into estrogen. [Source 1, 6] This estrogen then activates inflammatory and cell multiplication processes, directly promoting the growth of the prostate. [Source 1] Peat noted that men with the highest testosterone levels generally have the lowest estrogen and the lowest prostate cancer problems, framing a deficiency of testosterone as a consequence of this estrogenic conversion. [Source 1, 6]

The hormonal environment of aging creates a permissive state for BPH. Peat observed that by the age of 50, men often show an excess of both **prolactin** and **estrogen**, alongside a deficiency of thyroid and testosterone, which is precisely when prostate enlargement becomes noticeable. [Source 8] The active thyroid hormone T3 declines with age, which necessarily lowers the production of the protective steroids **pregnenolone** and **progesterone**. [Source 3] Progesterone, which Peat noted has been used in Europe to shrink enlarged prostates, and pregnenolone both decline, and their absence allows estrogen's effects to go unopposed. [Source 7, 8] Furthermore, estrogen rises in men during old age, as it does in stress, disease, and malnutrition, and is also produced in fat tissue, which tends to increase with age when thyroid and progesterone are deficient. [Source 3]

Peat identified several nutritional and hormonal interventions to oppose the estrogenic and inflammatory drivers of BPH. He considered **vitamin D** a major anti-inflammatory factor, possibly the single most important thing besides thyroid function, and recommended sunlight as the best source. [Source 1, 6] He also stressed keeping calcium intake high relative to phosphate to support metabolic balance. [Source 1, 6] To directly inhibit the aromatase enzyme that converts testosterone to estrogen, Peat pointed to *aromatase inhibitors* found in foods such as oranges (naringenin) and guavas (apigenin), as well as the drug aspirin, which blocks the production of inflammatory prostaglandins. [Source 2] The supplement pregnenolone was described as indirectly able to increase progesterone and lower estrogen production. [Source 2] Additionally, the raw carrot salad, made with grated carrots, olive oil, vinegar, and salt, was recommended for its mild antibiotic functions to reduce intestinal irritation and systemic endotoxin load, which can contribute to hormonal imbalance. [Source 1, 6]

Georgi Dinkov has extended this framework by challenging the causal link between BPH and prostate cancer, stating that it has never been proven that BPH will progress to cancer or that any causal relationship exists. [Source 5] He described the development of **5-alpha-reductase inhibitors** like finasteride as a "chemical castration therapy" designed to sell a drug by mimicking a deficiency of the enzyme that converts testosterone to DHT, a condition in which the prostate remains small. [Source 4, 5] Dinkov warned that these drugs lead to depression, suicide, feminization, and ironically, a more aggressive type of prostate cancer. [Source 5] He also highlighted the role of **serotonin** in directly stimulating the growth of prostate cancer and accelerating the conversion of BPH into high-grade cancer, noting that people on SSRI drugs have a dramatically higher chance of developing that type of cancer. [Source 10] To oppose this, Dinkov recommended anti-prolactin drugs, vitamin B6 (as pyridoxal 5-phosphate) to suppress prolactin and increase dopamine, and serotonin antagonists like *cyproheptadine*. [Source 10] Danny Roddy has noted that BPH, pattern baldness, and cardiovascular disease are tightly interrelated, reflecting a systemic problem rather than an isolated local condition. [Source 9]

## People also ask

### What role does estrogen play in prostate enlargement according to Ray Peat?

Peat argued that estrogen, not testosterone, is the primary driver of BPH, as a declining metabolic rate and thyroid deficiency in aging men cause testosterone to be converted into estrogen, which then activates inflammatory and growth processes in the prostate.

### How might a raw carrot salad help with benign prostatic hyperplasia?

The entry describes the raw carrot salad as a recommendation for its mild antibiotic functions, which reduce intestinal irritation and systemic endotoxin load, thereby helping to correct the hormonal imbalances that contribute to prostate enlargement.

### Why are 5-alpha-reductase inhibitors like finasteride considered dangerous in this framework?

Georgi Dinkov described these drugs as a "chemical castration therapy" that mimics an enzyme deficiency, warning they can lead to depression, suicide, feminization, and ironically, a more aggressive type of prostate cancer.

> **Patrick Timpone:** Dr. Ray Peat, we have time for a few more here. We could probably squeeze you in if you haven't emailed yet. Patrick, OneRadioNetwork.com. This is from Michael, Dr. Peat. He's in Connecticut. Are there any nutritional or hormonal approach to help reduce prostate enlargement, BPH? Oh, cool. Okay.
>
> **Ray Peat:** Yeah, balancing the hormones. Thyroid deficiency is... going to necessarily weaken your control and balancing processes. Your liver slows down and lets testosterone turn into estrogen. Estrogen activates inflammatory and cell multiplication processes. Men with the highest testosterone levels generally have the lowest estrogen and the lowest prostate cancer problems. A deficiency of testosterone usually is the result of low thyroid leading to the conversion of testosterone to estrogen, and estrogen promotes growth of the prostate and inflammation. So it's good to check your... your hormones. Vitamin D is a major anti-inflammatory factor. It might be the single most important thing besides thyroid function, a good vitamin D level.

> **Andrew Murray:** Well, the main aromatase inhibitor that I'm familiar with is from nettle root, and that's really used as a kind of prostatic agent in men to treat benign prostatic hypertrophy by blocking that enzyme. In terms of your condition and what you said about the weight gain and your age, it's not uncommon at all for what you're saying to occur. I think it happens fairly commonly. Dr. Peat, in terms of this lady's supposed low progesterone levels and the estrogen that she's been exposed to having gone into early menopause at 40, I know that you'd probably be... looking at her thyroid function as a main route with which to treat her situation in terms of her possible now Hashimoto's diagnosis?
>
> **Ray Peat:** Yeah, almost everyone around the age of 40, that's when the highest ratio of estrogen to progesterone exists. But the trouble is, the estrogen seems to drop when you measure it in the serum. even though it was at its very highest lifetime level around the age of 40. When progesterone falls, the estrogen can't be released from the cell, and so it doesn't appear in the serum until progesterone affects the cells to release it so that it can be measured. But that means that even without... taking something to increase your progesterone, the aromatase inhibitors are very practical and logical. Two fruits that contain effective aromatase inhibitors are oranges and guavas, apigenin. So this is naringenin? Yeah, in oranges, and then in guavas, I think there's one called apigenin. Apigenin, okay. Apigenin.

Ray Peat · Article · 2013

> It has seemed odd to many people that enlargement of the prostate should occur mainly in older men, if testosterone is the hormone that causes its growth, and estrogen is antagonistic to its growth. The nature of the growth of the old man's prostate is very different from its natural growth in youth.
>
> It was also recognized decades ago that estrogen rises in men during old age, as it rises in stress, disease, malnutrition, and hypothyroidism (which are also associated with old age). Estrogen is produced in fat which tends to increase with age, when thyroid and progesterone are deficient. The conversion of testosterone to estrogen occurs in the testicle itself, but this conversion is also inhibited by the favorable hormonal environment of youth. The active thyroid hormone, T3, declines with aging, and this necessarily lowers production of pregnenolone and progesterone. Increasingly, in both sexes, it appears that DHEA may rise during stress as a result of a deficiency of thyroid, progesterone, and pregnenolone.
>
> In 1786, John Hunter reported that castration causes a decrease in the size of the prostate gland, and by the end of the 19th century castration was being advocated for treating enlargement of the prostate. In aging men, the prostate gland (both central and peripheral zones) atrophies, and it is within the atrophic gland that cancer cells can be found. Nodular, noncancerous enlargement may occur, with or without cancer. In 1935, an autopsy study showed carcinoma in the prostates of 30 of men by the age of 50. Proliferation of ductal and epithelial tissue is closely associated with prostate cancer, a situation similar to that of the cancerous or precancerous breast. The high probability of epitheliosis in association with cancer was seen in women in their early 40s, and in women over 60. (Epitheliosis just refers to an exaggerated proliferation of epithelial cells, the cells covering all surfaces, including the lining of glands, and things as simple as irritation and vitamin A deficiency can cause these cells to proliferate.) In the breast, the proliferative epitheliosis is clearly caused by estrogenic stimulation. The antagonism between estrogen and vitamin A in controlling epithelial proliferation (and possibly other cell types) is clear wherever it has been tested; vitamin A restrains epithelial proliferation.

Danny Roddy · Book · 2013

> Hamilton’s eunuchs, the Guevedoces were conspicuously free of pattern baldness and acne. The affected males were found to have normal plasma testosterone concentrations, but were deficient in dihydrotestosterone (DHT), a derivative of testosterone. Upon further research, Dr. Imperato-McGinely’s group ended up discovering the first inherited disorder of steroid hormone metabolism, a deficiency of the 5-alpha reductase enzyme (5-AR) that converts testosterone into DHT. Because the Guevedoces had normal levels of testosterone in their blood, Dr. Imperato-McGinely’s group surmised that DHT, rather than testosterone, had to be responsible for bringing about baldness. Regardless of the implications of Imperato-McGinley's research, it wouldn't have mattered much in the grand scheme of things. Normally, gathering data and forming intelligent hypotheses would lead to various tests, which would eventually eliminate mistaken ones. However, in the case of pattern baldness, the virtue of science was shortchanged when the pharmaceutical companies stepped in.

> ### Becoming The Castrate
>
> In 1974, a monograph of a conference Dr. Imperato McGinley spoke at landed on the desk of Merck pharmaceutical’s research chief, Dr. Vagelos. Vagelos was intrigued by Imperato-McGinley’s research and more specifically by her notation that the prostate glands of those with inherited 5-AR deficiency remained small throughout life. Dr. Vagelos thought that if Merck could mimic the Guevedoces’ 5-AR deficiency with a drug, it might have a product for the market of 15 million American men suffering from enlarged prostate glands (benign prostate hyperplasia or BPH), an embarrassing and often painful condition that can block urine flow, interrupt sleep and predispose to serious infections. Merck spearheaded the concept, eventually producing Finasteride (marketed as Proscar), a type-II 5-alpha-reductase inhibitor that reduces, quite significantly, the concentrations of DHT in the body. Finasteride, as a side effect, also regrew hair. Merck lowered the dose of Proscar from 5mg to 1mg, and, in 1997, introduced the world to Propecia – the first FDA-approved drug for male-pattern baldness – to immediate popularity.

> **Georgi Dinkov:** They said, oh, well, one of the first things that we see before prostate cancer develops is that these people usually go through a stage called BPH, benign prostate hyperplasia. They said it's a risk for prostate cancer. It has never been proven that actually it will progress to prostate cancer. It's never been proven that it has any causal relationship whatsoever. But they said, no, DHT really enlarges your prostate. We actually need to develop a treatment for it. And what did they do? They developed something called chemical castration therapy. And it's really, that's how it's known to this day officially. Used to be a combination of physical and chemical castration, but many men started balking at the idea of having their balls cut off. So they said, we're not gonna be able to sell many men on that surgery. might as well develop something that's, you know, they can do it chemically. But don't make no mistake, you may be keeping your nuts down there, your nuggets, but they're not working anymore when they give you the chemical castration drugs. And those chemical castration drugs are drugs that either inhibit the synthesis of DHT, they're known as 5-alpha reductase inhibitors, the most notorious one being finasteride, and that's a whole separate story of just how many lives finasteride has ruined. Now there are actually massive class action lawsuits being prepared in America to sue the manufacturers of finasteride, which lie to people saying, oh, it's perfectly safe. You don't need DHT. Testosterone is perfectly sufficient to maintain you as a male. As it turns out, not. Not only not, but hell not. It leads to depression. It leads to suicide. It leads to feminization. It leads to liver cancer. It leads to prostate cancer. Actually, a very aggressive type of prostate cancer. Prostate cancer is perhaps the one cancer where even a mainstream doctor, if you're an older male and you go to them, they'll give you a test. They even may do a biopsy.

> Interesting. And this could be, this carrot salad, even a couple times a day? Or it's fine? Yeah, it's fine. Yeah, and an extreme person might eat three carrots a day, but usually one middle-sized carrot is enough every day. That's the grated up olive oil, a little vinegar, and some salt. That's great. Mark writes in, my wife is constantly trying to clear her throat all day long. She likens it to phlegm and can never get it cleared. Silent reflux has been rolled out. And Ella just gave her medication. She thinks, oh, she inhales through the nose, but that hasn't helped. And she takes no other medication. I'm wondering what we could try to do now. There are reflexes so that irritation somewhere else can cause excess mucous production in the nose or sinus area, or throat, and... so making sure that the intestine isn't being irritated, sometimes just finding a spice that... pepper, for example, or celery, or... many particular foods can cause chronic irritation in the intestine with the reflex, excess mucus production up in the upper respiratory system.

>
> **Ray Peat:** Yeah, and it stops the vascular problems that are involved in the blind spots of migraine. In two of my worst migraines ever I found that in a minute and half the headache totally resolved, and in women it is less likely to have such a quick massive effect because women are likely to have a much higher estrogen level. Estrogen causes nerve sensitivities which can culminate in epilepsy, but migraine is the lower grade of this estrogen poisoning. And the effect on the vascular system of progesterone is in the direction of digitalis that’s considered to be the body's own heart and circulation regulatory substance which is affected by digitalis and this means that it tones up, for example, varicose veins or bulging veins on the backs of your hands or an easy way to see a progesterone deficiency but that’s what happens in a migraines of bulging veins impaired circulation.

Ray Peat · Article · 2013

> In human prostate slices, several hormones (including insulin, and probably prolactin) stimulated cell division; testosterone did not, under these experimental conditions. Contrary to the stereotyped ideas, there are suggestions that supplementary androgens could control prostate cancer, and that antagonists to prolactin and estrogen might be appropriately used in hormonal therapy.
>
> By the age of 50, men often show an excess of both prolactin and estrogen, and a deficiency of thyroid and testosterone. This is the age at which enlargement of the prostate often becomes noticeable.
>
> Estrogen's role in prostate growth and cancerization is clear: …simultaneous treatment of intact…rats with testosterone and estradiol-17beta for 16 weeks consistently induced a putative precancerous lesion, termed dysplasia, in the dorsolateral prostate of all animals. Since treatment of rats with androgen alone did not elicit the same response, we concluded that estrogen played a critical role in the genesis of this proliferative lesion.
>
> Progesterone and pregnenolone also decline in aging men. Several studies using synthetic progestins have shown that they effectively shrink the hypertrophic prostate, and the saw palmetto remedy for prostate enlargement has been reported to contain pregnenolone, or something similar to it. These materials might be expected to reduce conversion of testosterone or other androgens to estrogen.
>
> The prostaglandins were discovered in prostatic fluid, where they occur in significant concentrations. They are so deeply involved with the development of cancers of all sorts that aspirin and other prostaglandin inhibitors should be considered as a basic part of cancer therapy. The prostaglandins have local and systemic effects that promote cancer growth. (The prostaglandins and related eicosanoids synthesized from polyunsaturated fatty acid precursors have been implicated as modulators of tumor metastasis, host immunoregulation, tumor promotion, and cell proliferation.)
>
> Estrogens cause elevation of free fatty acids, and there are many interactions between the unsaturated fatty acids and estrogen, including their metabolism to prostaglandins, and their peroxidation. Estrogen's roles as free-radical promoter, DNA toxin, carcinogen, tumor promotor, modifier of tissue growth factors, anti-thymic hormone, etc., as well as its local effects on the prostate gland, have to be kept in mind.

> **Danny Roddy:** One of my favorite things, I think, in Ray's newsletter where he talks about prostate cancer is when the physicians were asked what they would do if they had prostate cancer. And most of them just said they'd do nothing.
>
> **Georgi Dinkov:** Well, yeah. Wikipedia, which is the consensus of the people here, especially the medical establishment, it says the five-year survival rate is 99%, right? So the chance of you dying from prostate cancer is lower than probably, I don't want to say that, but it's comparable to probably getting hit by a car on the street. And most people take that risk every day. So other things that people can do other than the androgens is oppose prolactin. And several reasons for that. Basically, prolactin, like I said, is not just a metabolic inhibitor. It's shown to be directly a positive factor in the development and progression of prostate cancer. So basically, anti-prolactin drugs like bromocriptine, lyseride... cabergoline, methisargate will probably be helpful on the non-pharmacological field of things. Vitamin B6, especially its activated version, pyridoxal 5-phosphate, small doses, 5 to 10 milligrams a day, have been shown to suppress prolactin and consequently increase dopamine. And why is it important to increase dopamine? Dopamine also inhibits the synthesis of serotonin. And serotonin was recently found to directly stimulate the growth of prostate cancer, to convert the more or less benign condition, because that's what it's called, BPH, benign prostate hyperplasia, to accelerate the conversion of BPH into high-grade prostate cancer. And the study initially was done as an epidemiological study. They noticed that people on SSRI drugs have a dramatically higher chance of getting that type of cancer. So then they did an actual direct study, and it was confirmed. And it looks like it's the – if you believe in receptors, it's the serotonin receptors 1 and 2 that are involved. So taking antagonists to those receptors are good old friends, cyproheptadine, and meanserin, ketanserin, mirtazapine, all of the serins is probably going to be beneficial for – for conditions of the prostate.

> When I read through the studies cited by the current articles as the basis for using estrogen to treat prostate cancer, I saw that the decisive research had consisted of mailing a questionnaire to physicians asking them if they thought it was reasonable to administer estrogen to these patients on the basis of its opposition to testosterone, which was considered to be responsible for the growth of the prostate gland.

Phrases such as it is indicated, treatment of choice, and standard practice are used in medicine, as part of the pseudo-scientific mystique of the profession. Physicians who attempt to base their practice on methods that have a sound scientific basis are likely to find that they are violating the norms of their profession.
