What hormone does BPA mimic?

Author: Prof. Pasquale Crooks  |  Last update: Monday, July 7, 2025

BPA can mimic estrogen to interact with estrogen receptors α and β, leading to changes in cell proliferation, apoptosis, or migration and thereby, contributing to cancer development and progression.

Does BPA mimic testosterone?

In details, BPA administration reduces testosterone biosynthesis and secretion, thus inhibiting the activity of GnRH neurons, and lowering the expression of steroidogenic enzymes. Consequently, a decline of testosterone levels and a reduction in spermatozoa concentration was seen.

What is similar to BPA?

Other Bisphenols

With increasing regulations on and a subsequent decline in, the use of BPA, alternatives such as bisphenol S (BPS) and bisphenol F (BPF) have increasingly been used as replacements.

What hormone does PCB mimic?

PCBs can mimic the effect of the hormone estrogen on the body, contributing to a variety of neuroendocrine, metabolic and reproductive problems.

Do endocrine disruptors mimic estrogen?

Examples of endocrine disruptors that mimic hormones are xenoestrogens, chemicals that mimic human estrogen. Examples include BPA, PCBs, parabens, pesticides, and more. Xenoestrogens may play a role in an estrogen-dominant hormone pattern that cause symptoms like PMS, tender breasts, and heavy bleeding.

Endocrine Disrupting Chemicals (EDCs)

Is BPA an endocrine disruptor?

BPA is a known endocrine disruptor. Although initially considered to be a weak environmental estrogen, more recent studies have demonstrated that BPA may be similar in potency to estradiol in stimulating some cellular responses.

How to rid your body of endocrine disruptors?

A person cannot remove endocrine disruptors from the body. A person also cannot avoid EDCs completely, as traces of EDCs are often present in the surrounding environment. However, it is possible to reduce exposure to some endocrine disruptors by choosing products free from EDCs.

What are the symptoms of PCB toxicity?

Appetite loss has been reported in transformer and electrical equipment manufacturing workers exposed to various PCB-containing mixtures. Other nonspecific gastrointestinal symptoms experienced by workers exposed to PCBs include nausea, epigastric distress and pain, and intolerance to fatty foods [Emmett et al.

Is there anything that mimics estrogen?

One group of phytochemicals, called phytoestrogens, mimics estrogen. When eaten, your body absorbs them during digestion and recognizes them as estrogen. The most common phytoestrogens are: Coumestan.

How do PCBs affect the thyroid?

Developmental exposure to PCBs is associated with neuropsychologic deficits, which may be related to effects on thyroid hormone (TH) signaling in the developing brain. However, PCBs may interfere with TH signaling solely by reducing circulating levels of TH, or they may exert direct effects on TH receptors (TRs).

What does BPA mimic?

BPA mimics the structure and function of the hormone estrogen. Due to its estrogen-like shape, BPA can bind to estrogen receptors and influence normal bodily processes. These include growth, cell repair, fetal development, and reproduction.

What are the cousins of BPA?

While bisphenol A (BPA) is the most well-known member of this chemical class, similar compounds such as bisphenol S (BPS) and bisphenol F (BPF) are chemical cousins that are also of concern.

How do you know if you have BPA?

The most reliable way to check whether an item is BPA-free is to consult the plastic identification code number — usually stamped on the bottom of the container. There are seven categories, where numbers 1 to 6 are free of BPA. This means that only those printed with the number 7 will contain the chemical.

Is BPA linked to gender dysphoria?

An endocrine disrupting chemical (EDC), bisphenol A (BPA), acts as oestrogen mimic compund. BPA may affect sexual differentiation of brain and cause reversal of differentiation in male to female transsexual as female brain.

What does BPA do to men?

In particular, as an antagonist for both androgen and estrogen receptors (ERs), BPA has been found to damage male fertility by altering hormone receptor binding functions (Rahman et al., 2015), thus disrupting male reproductive functions such as sperm motility/motion kinematics, reproductive organ weights and the ...

Can you test your body for BPA?

BPA is broken down into metabolites in the body, so the best way to test actual levels would be to measure intact BPA plus the total of the metabolites. Unfortunately, regulatory agencies like the FDA only use testing methods that indirectly measure metabolite levels.

What mimic the hormone estrogen?

Phytoestrogens are naturally occurring compounds found in over 300 plants . They mimic estrogen, which is a hormone that has many functions in the body. In females, estrogen influences sexual development, menstruation, and libido.

What is the strongest natural estrogen?

Estradiol (E2) is the primary form of estrogen in your body during your reproductive years. It's the most potent form of estrogen.

What drink is high in estrogen?

Red wine is rich in resveratrol, a phytoestrogen researchers believe reduces heart disease risk by regulating cholesterol levels. Another study found that phytoestrogens in red wine may stop cancer cell growth, particularly among postmenopausal women.

What foods are high in PCBs?

Salmon had the highest concentration followed by canned tuna, but fish is a minor contributor to exposure. Other animal proteins are more important sources of PCB dietary exposure in this study population.

Can your body get rid of PCBs?

PCBs are easily absorbed by the body and are stored in fatty tissue. PCBs are not eliminated well, so they can accumulate in the body. Most people are exposed to PCBs by eating contaminated fish, meat, and dairy products. Catfish, buffalo fish, and carp usually have the highest PCB levels.

What does PCB smell like?

PCBs have no known taste or smell, and range in consistency from an oil to a waxy solid.

How do you flush hormones out of your body?

What are 8 places you may be exposed to endocrine disruptors?

Endocrine disruptors are found in many everyday products, including some cosmetics, food and beverage packaging, toys, carpet, and pesticides. Some chemicals that act as flame retardants may also be endocrine disruptors. Contact with these chemicals may occur through air, diet, skin, and water.

Are eggs endocrine disruptors?

Several endocrine disruptors such as hexachlorobenzene (HCB), polychlorinated naphthalenes (PCNs), polychlorinated-dibenzodioxins, polycyclic hydrocarbons (PAHs) have all been found in eggs from polluted sites (Domingo 2014; Pajurek et al.
