When BPA is ingested or absorbed by the body, it can mimic the action of the hormone estrogen, which can disrupt the normal balance of hormones in the body. This can lead to a range of health effects, including:

Reproductive problems: BPA can affect fertility in both men and women by interfering with the normal production and function of hormones such as estrogen, progesterone, and testosterone. It has been linked to decreased sperm count and motility in men, as well as menstrual irregularities and decreased fertility in women.

Developmental problems: BPA exposure during pregnancy or early childhood can affect the development of the reproductive system and other organs in the body, which can have long-term effects on health and development.

Increased risk of certain cancers: Some studies have suggested that BPA exposure may increase the risk of certain types of cancer, including breast and prostate cancer.

Obesity and diabetes: BPA has also been linked to an increased risk of obesity and type 2 diabetes, as it can interfere with the normal function of insulin and other hormones that regulate metabolism.

The exact mechanisms by which BPA affects hormones in the body are not fully understood, but it is believed to interfere with the normal signaling pathways that hormones use to communicate with cells. In particular, BPA can bind to hormone receptors in the body and either activate or block their activity, depending on the specific hormone and receptor involved.

Overall, the effects of BPA on hormones and human health are an active area of research, and more studies are needed to fully understand the extent of the risks and how to mitigate them. In the meantime, many experts recommend limiting exposure to BPA by avoiding certain plastic products, such as those labeled with recycling codes 3 and 7, and using alternatives such as glass or stainless steel whenever possible.
