“…Furthermore, blood MeHg level was significantly increased in infertile women compared to pregnant women and persistent with fish usage frequency. Compared to the reference blood MeHg concentration of <5.8 µg/L, the higher blood MeHg concentration (≥5.8 µg/L) found in infertile women was related to a 3.35 and 4.42-folds of risk associated with fish consumption of 1-2 meals/week or >3 meals/week, respectively ( 60 ). Moreover, there was no evidence of neonatal impairment related with mercury exposure due to consumption of fish during pregnancy and women should be confident that consuming fish during pregnancy is advantageous for their unborn child ( 61 ).…”

Mercury is a toxic heavy metal. Humans are exposed to mercury through several sources including environmental, occupational, contaminated food and water and from mercury-containing dental amalgam. Mercury exposure is known to harm the nervous system profoundly, and have a negative impact on digestive and immune systems, and other organs. To review and discuss the effect of mercury exposure through environmental or occupational routes on human reproduction, pregnancy, and its outcome. Published information about the potential toxic effects of mercury on human reproduction were collected and summarized. Literature was identified by systematic search using relevant keywords. Literature review revealed a number of negative impacts of mercury on human reproduction. These included effects on semen quality, including reduced sperm count, motility, and changes in morphology that may reduce fertility potential. There may also be an effect in changing reproductive hormone levels. Mercury exposure might also affect pregnancy but the data concerning mercury effects on female reproduction are limited except for some data about mercury exposure and poor pregnancy outcomes. Available data indicate that mercury exposure may have a toxicity effect on reproductive potential, especially in males. Prenatal mercury exposure may affect pregnancy or its outcome and this appears to be dependent upon dose, duration, and timing of exposure. Nutritional status of exposed individual might also influence the impact of mercury.

“…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.

“…Some epidemiological and experimental studies examined the associations and the effects of Hg exposure on female reproductive outcomes [16,18,24,27,28,[31][32][33]35,36,38,[40][41][42][43]45,47,48,52,53,55,57]. Positive correlations between Hg concentrations in blood and hair and unexplained infertility (r = 0.48; p < 0.01) were found [31,57].…”

“…Female reproduction is a process regulated by hormones and is susceptible to the effects of exposure to endocrine disrupting chemicals. Some studies reported that Hg may influence physiologic levels of female reproductive hormones [27,38,43,45,53]. Gerhard et al [27] reported that women with thyroid dysfunction and polycystic ovary (PCO) syndrome showed a higher urine Hg excretion compared to controls without hormonal disorders.…”
