“…Zhao et al [ 44 ] reported that the lower educational level was a risk factor for infertility. Previous research has shown that the levels of zinc, magnesium, and iron were significantly decreased in diseases associated with female infertility [ 45 , 46 , 47 ], which was consistent with our results, indicating that inadequate levels of micronutrients are related with unfavorable reproductive function [ 10 ]. Interestingly, in the infertile group, the levels of copper, zinc, magnesium, and iron were lower in the Prevotella -enterotype.…”

Infertility is defined as failure to achieve pregnancy within 12 months of unprotected intercourse in women. Trace elements, a kind of micronutrient that is very important to female reproductive function, are affected by intestinal absorption, which is regulated by gut microbiota. Enterotype is the classification of an intestinal microbiome based on its characteristics. Whether or not Prevotella-enterotype and Bacteroides-enterotype are associated with blood trace elements among infertile women remains unclear. The study aimed to explore the relationship between five main whole blood trace elements and these two enterotypes in women with infertility. This retrospective cross-sectional study recruited 651 Chinese women. Whole blood copper, zinc, calcium, magnesium, and iron levels were measured. Quantitative real-time PCR was performed on all fecal samples. Patients were categorized according to whole blood trace elements (low levels group, <5th percentile; normal levels group, 5th‒95th percentile; high levels group, >95th percentile). There were no significant differences in trace elements between the two enterotypes within the control population, while in infertile participants, copper (P = 0.033), zinc (P < 0.001), magnesium (P < 0.001), and iron (P < 0.001) in Prevotella-enterotype was significantly lower than in Bacteroides-enterotype. The Chi-square test showed that only the iron group had a significant difference in the two enterotypes (P = 0.001). Among infertile patients, Prevotella-enterotype (Log(P/B) > −0.27) predicted the low levels of whole blood iron in the obesity population (AUC = 0.894; P = 0.042). For the high levels of iron, Bacteroides-enterotype (Log(P/B) <−2.76) had a predictive power in the lean/normal group (AUC = 0.648; P = 0.041) and Log(P/B) <−3.99 in the overweight group (AUC = 0.863; P = 0.013). We can infer that these two enterotypes may have an effect on the iron metabolism in patients with infertility, highlighting the importance of further research into the interaction between enterotypes and trace elements in reproductive function.

“…However, the results were obtained may still controversially. 14 And it is known that , consumption of protein has the same capacity of insulin secretion stimulation, like consumption of carbohydrates, moreover, it was revealed that , not all products that containing protein may exert the same effect on secretion of insulin and modulation the sensitivity of insulin in tissues in different manner. 15,16…”

“…2 A probiotic must be colonized and adherent to the gastrointestinal tract (GIT), it must be replicated to reach high numbers, as well as antimicrobial substances must be produced by it, beside provided an acidic environment in the GIT. [11][12][13][14][15][16][17][18] The definition of hypercholesterolemia is, an increase of plasma cholesterol levels excessively above 200 mg/dL, the patients may have a strong risk to cardiovascular disease. 4 The cholesterol totally can be degraded into a diagnostic profile of lipoprotein, including LDL, intermediate density lipoproteins…”

For managing the digestive tract and immune system, probiotic has been recommended more frequently as an effective therapy and are known as the agent of cholesterol-lowering. The definition of hypercholesterolemia is, increase of plasma cholesterol levels excessively above 200 mg/dL, the patients may have a strong risk to cardiovascular disease. The aims of this study is used different types of probiotic sources of treating patients with hypercholesterolemia with no cardiovascular disease for 30 days. The results show that, there are significant differences (p < 0.05) between cholesterol, Low-density lipoprotein (LDL) and High-density lipoprotein (HDL) before and after the consumption of probiotics from different sources, while triglyceride and glucose show there are no significant differences after 30 days (p > 0.05).

“…Diet has also been investigated on the role of hormonal imbalances especially since the production of androgens is related to IR. Studies are still at early stages, looking at the potential effect of dairy and starch on the hormonal profile of PCOS women [144][145][146]. Studies where women were asked to follow a low starch and low dairy diet presented mixed results and the role of these foods on hormonal profiles requires more research.…”

The Role of Probiotics and Synbiotics on Hirsutism

Probiotics and synbiotics are known to have beneficial effects on human health and disease. Hirsutism, a disorder that is characterised by the presence of coarse terminal hairs in a male-like pattern, is usually caused by elevated androgen levels in blood plasma. This disorder is usually observed in PCOS women and it is linked to insulin resistance (IR). Although idiopathic hirsutism (IH) is not shown to have excess androgen production from the ovarian and adrenal glands, increased 5α-reductase in peripheral tissues and insulin resistance are common observations. The effect of probiotics and synbiotics have been recently studied on PCOS women; androgens were also included in the hormonal groups that were investigated. Only a few studies focus on hirsutism and the potential effect of the beneficial microbes mentioned, whereas the increasing interest on insulin resistance and synbiotics indicate a potential beneficial effect on hirsutism through the management of insulin resistance.
