A pandemic is an epidemic that spreads globally. Coronavirus disease 2019 (COVID-19) caused a major pandemic that affected human health and activities around the world since the beginning of 2020 and became a major international emergency. Through multiple paths, COVID-19 pandemic influenced life at individual, familial, societal, and environmental levels and led to a global economic recession. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for the disease. It invades the target cells by binding to angiotensin-converting enzyme 2 (ACE2). Endocrine and metabolic systems can be implicated in COVID-19 infection. Subjects with several comorbidities (e.g., hypertension, diabetes, and obesity) are more likely to be infected and are at a higher risk for complications and death from COVID-19. Wearing mask, social distancing, home confinement, and isolation have been recommended and implemented in several countries to curb the spread of the outbreak. Vaccination remains the best protective measure. Different vaccines are now available and have been used. The worldwide impact of COVID-19 pandemic may last several years.

Endocrine-disrupting chemicals have received significant concern, since they ubiquitously persist in the environment and are able to induce adverse effects on health, and more particularly on reproductive function. Most of the studies focused on nuclear hormone receptors as mediators of sex steroid hormones signaling. However, there are increasing evidences that peptides hormones of the Hypothalamo-Pituitary-Gonadal axis are targets of endocrine-disrupting chemicals (as Gonadotropin-Releasing Hormone, Follicle-Stimulating Hormone, Luteinizing Hormone…). The majority of these hormones act on G protein-coupled membrane receptors. This review summarizes the effects of endocrine-disrupting chemicals on homeostasis of peptides hormone of Hypothalamo-Pituitary-Gonadal axis and on their G protein-coupled membrane receptors signaling revealed by experimental, clinical, and epidemiological studies in human.

Bisphenol A (BPA), an endocrine disruptor involved in synthesizing numerous types of plastics, is detected in almost the entire population’s urine. The present work aims to estimate daily exposure to BPA by systematically reviewing all articles with original data related to urinary BPA concentration. This approach is based on human pharmacokinetic models, which have shown that 100% of BPA (free and metabolized form) is eliminated only in a few hours through urine. Several extensive population studies and experimental data have recently proven a significant association between urinary excretion of BPA and albuminuria, associated with renal damage. Our team’s previous work has shown that low-dose BPA can promote a cytotoxic effect on renal mouse podocytes. Moreover, BPA administration in mice promotes kidney damage and hypertension. Furthermore, preliminary studies in human renal cells in culture (podocytes) strongly suggest that BPA might also promote kidney damage. Overall, the present review analyzed BPA exposure data from mammalian cell studies, experimental animal models, and several human populations. Studying principal cohorts calculated the exposures to BPA globally, showing a high BPA exposure suggesting the need to decrease BPA exposure more effectively, emphasizing groups with higher sensitivity as kidney disease patients.

The hypothalamic–pituitary-gonadal (HPG) axis plays a crucial and integrative role in the mammalian endocrine regulation to maintain homeostasis. The HPG axis is primarily responsible for governing all the hormonal events related to reproductive activity. Endocrine-disrupting chemicals (EDCs) comprise a diverse group of naturally occurring and synthetic compounds that mimic and interfere with the endogenous chemical hormones. Epidemiological investigations have shown increasing evidence of altered development and detrimental effects on reproductive health during the past 50 years associated with endocrine disruptors affecting the HPG axis. The pleiotropic harmful effects of EDCs act through hormone-dependent downstream signaling pathways responsible for gonad development either through direct interaction with steroid hormone receptor or via epigenetic regulation. Hence, this chapter summarizes the biological plausibility of EDCs exposure and elucidates the mechanism of action underlying EDCs affecting the regulatory circuits of the mammalian HPG axis and reproductive function.
