Mercury (Hg), a highly toxic environmental pollutant, shows harmfulness which still represents a big concern for human health, including hazards to fertility and pregnancy outcome. Research has shown that Hg could induce impairments in the reproductive function, cellular deformation of the Leydig cells and the seminiferous tubules, and testicular degeneration as well as abnormal menstrual cycles. Some studies investigated spontaneous abortion and complicated fertility outcome due to occupational Hg exposure. Moreover, there is a relation between inhaled Hg vapour and reproductive outcome. This MiniReview evaluates the hypothesis that exposure to Hg may increase the risk of reduced fertility, spontaneous abortion and congenital deficits or abnormalities.

“…Mercury has a negative role in fertility, both in men and women. 95,96 In women, infertility is influenced by an imbalance of the female hormonal system due to Hg exposure. The progesterone/oestrogen ratio changes in favour of oestrogen growth, which inhibits the release of LH-luteinizing hormone.…”

“…The main sources of mercury in milk include diet rich in fish (especially marine) (Grzunov Letinić et al 2016 ), amalgam fillings (Drasch et al 1998 ; Drexler and Schaller 1998 ; Grzunov Letinić et al 2016 ), and residence in mining areas (Bose-O’Reilly et al 2008 ). The findings of epidemiological studies (98 infertile female patients and a control group of 43) conducted by Maeda and co-workers (Maeda et al 2019 ) suggest that methylmercury may affect female fertility.…”

Breastfeeding is a gold standard of neonate nutrition because human milk contains a lot of essential compounds crucial for proper development of a child. However, milk is also a biofluid which can contain environmental pollution, which can have effects on immune system and consequently on the various body organs. Polychlorinated biphenyls are organic pollutants which have been detected in human milk. They have lipophilic properties, so they can penetrate to fatty milk and ultimately to neonate digestive track. Another problem of interest is the presence in milk of heavy metals—arsenic, lead, cadmium, and mercury—as these compounds can lead to disorders in production of cytokines, which are important immunomodulators. The toxicants cause stimulation or suppression of this compounds. This can lead to health problems in children as allergy, disorders in the endocrine system, end even neurodevelopment delay and disorder. Consequently, correlations between pollutants and bioactive components in milk should be investigated. This article provides an overview of environmental pollutants found in human milk as well as of the consequences of cytokine disorder correlated with presence of heavy metals. Graphical abstract

“…There is a worldwide concern with exposure to mercury, especially in riverine communities where high amounts of contaminated fish are consumed, as this chemical element has adverse health effects. And if women of reproductive age are contaminated, it can also affect reproduction (33)(34)(35)(36) . Studies point to possible problems related to reproduction: increased risk of reduced fertility, spontaneous abortion, congenital deficiencies and/or abnormalities (33)(34)(35) .…”

“…Considering this problem, studies recommend monitoring the levels of mercury in riverine women of reproductive age, since children under 24 months of age, who still do not eat fish, already have concentrations of mercury above the safety level, suggesting intrauterine contamination and/or contamination by breast milk (19,26,(33)(34)(35)(36) .…”

Objective: To analyze the scientific evidence available on the sexual and reproductive health of riverine communities. Method: Integrative review, conducted on the databases LILACS, MEDLINE; WEB OF SCIENCE and SCOPUS, including publications in Portuguese, English or Spanish, without an initial time limit and published until 2018. Results: 11 studies were selected. The studies included are from the period 1993-2017. The results originated four analytical categories: sexual component, which gathered findings about sexually transmitted infections; reproductive component, which included family planning/fertility control, abortion and problems with pregnancy; environmental component, which presented issues with environmental contaminants and its reproductive implications; and the sociocultural component, which discussed gender, beliefs and social indicators. Conclusion: In this review, studies with a quantitative approach, from a female point of view and a biological perspective predominated. No study investigated the meanings and representations of SRH for the riverine communities. In addition, the findings show little evidence of thoughts and practices of people living in riverine communities regarding SRH issues, providing limited evidence.
