Another reason for concern, especially for parents, may be because some animal studies report effects in fetuses and newborns exposed to BPA. Some animal studies suggest that infants and children may be the most vulnerable to the effects of BPA. Parents and caregivers can make the personal choice to reduce exposures of their infants and children to BPA:.

People experience frequent exposure to very small amounts of BPA through food, drinks, and water supplies, because small amounts may migrate from food packaging. In this article, we discuss what BPA is, what its sources are, and what impact it might have on human health.
BPA is an endocrine disruptor. For example, it can behave in a similar way to estrogen and other hormones in the human body. According to the NIEHS , there is limited research to show how endocrine disruptors affect humans, but some research has found they can harm animals. However, even a small amount may have developmental and biological impacts, because the balance of hormones is so sensitive.
In , scientists published study findings showing that BPA exposure can affect egg maturation in humans. A review found evidence that BPA can interfere with endocrine function involving the hypothalamus and pituitary gland. The researchers suggest that this type of action can affect puberty and ovulation and may lead to infertility.
The findings indicate that high level exposure may increase the risk of erectile dysfunction and problems with sexual desire and ejaculation. Research in humans has linked even low dose BPA exposure to cardiovascular problems, including coronary artery heart disease, angina , heart attack , hypertension , and peripheral artery disease.
Findings from animal studies indicate this type of exposure could trigger arrhythmias , atherosclerosis , and blood pressure changes. There is evidence that human exposure to BPA may contribute to :. Tests in animals have shown that BPA may aggravate or raise the risk of:.
Environmental exposure to BPA has the potential to affect the developing brain during gestation, according to research. The impact includes changes in structural development, interference with estrogen regulation, and DNA modifications. This could have effects on social behavior and anxiety after birth, says one study. Scientists believe BPA, with its estrogen-like behavior, could increase the risk of breast , prostate , and other cancers in people who experienced exposure to the chemical in the womb.
In , a group of researchers concluded that exposure to BPA before birth could have long-term effects on carcinogenesis in certain organs. This in turn could lead to the development of hormone-related cancers. In , scientists reported that BPA could interfere with the effectiveness of chemotherapy in breast cancer treatment.
