Exposure to even small amounts of toxic metals found in drinking water and food may cause eggs in women's ovaries to deplete faster, a study has warned. In addition, Research from the University of Michigan, have shown that middle-aged women with high levels of these metals may be at risk to obtain earlier menopause.
Metals, including arsenic and cadmium, possess endocrine disrupting characteristics and may be potentially be toxic to the ovaries. The study demonstrated for arsenic, AMH levels the barometer for interpolating egg reserves were 32.1 percent lower than women who had lower amount of the metal in their urine.
Therefore, toxic metals can affect the ovaries as such in the following ways. Interference with oogenesis or egg development. Toxic exposures to metals during fetal development or throughout a woman's lifetime can cause damage to the oocytes (eggs) in the ovaries. This damage may manifest later in life as reduced fertilization.
Accelerated follicle depletion: Certain metals, such as arsenic, can accelerate the depletion of ovarian follicles, which are responsible for producing eggs. This can lead to premature ovarian failure or early menopause.
Increased risk of ovarian cancer: Some metals, like lead and mercury, are known carcinogens. Chronic exposure to these metals can increase the risk of ovarian cancer.
Hormonal disruption: Endocrine-disrupting chemicals, including certain metals, can interfere with the normal hormonal balance in the body. This disruption can affect the growth, differentiation, and function of ovarian tissues and organs.
Impact on reproductive function: Exposure to toxic metals can result in ovarian dysfunction, including irregular menstrual cycles, hormonal imbalances, and reduced fertility.
It's important to note that the effects of toxic metals on the ovaries can vary depending on the specific metal, the level and duration of exposure, and individual susceptibility. Regular monitoring and minimizing exposure to toxic metals are imperative for maintaining ovarian health.
