A Animal Study published in 2023 in the journal Foods found that Long-term intake of traditionally made Doenjang, particularly high in certain species, may improve symptoms of estrogen deficiency more effectively than unfermented soybeans. The study involved using four different types of traditionally made Doenjang (TMD), distinguished based on the quantities of certain species and biogenic amines they contained. These were used to observe possible alterations in energy, glucose, and lipid metabolism in estrogen-deficient female rats via potential modification of the gut microbiota. This involved comparing a control group of rats that underwent ovary removal with five other groups that were supplemented with different types of TMD and cooked soybeans. The outcomes revealed that weight gain and visceral fat mass were lower and lean body mass was higher in the TMD and cooked soybean intake groups compared to the control group, however, these figures were not as good as those in the normal control group. Additionally, the hepatic triglyceride content was lower with TMD intake. It was further observed that the intestinal health significantly improved in the TMD groups, and some groups revealed more improvements than others. Concerning gut microbiota, certain groups showed an increase in certain types of organisms, suggesting a benefit from high amounts of the specific species in TMD. The study inferred that TMD rich in certain species correlates positively with the regulation of estrogen-related markers.

A Review Article published in 2022 in the journal Comprehensive Reviews in Food Science and Food Safety found that Pumpkin seed oil, with its phytochemical content, shows beneficial properties against cardiovascular problems in menopausal women and hormone imbalances. The study focused on gathering scientific information that highlights the potential of pumpkin seed oil as a health-benefiting food ingredient. Its focus is on the oil’s chemical composition, phytochemical content, biological activity, safety measures alongside the various production processes. The researchers examined major phytochemicals found in the oil, including polyphenols, phytoestrogens, and fatty acids, while also noting the potential health benefits of carotenoids, squalene, tocopherols, and minerals present in it. In terms of methodology, most studies within this review were conducted in vitro to validate the oil's antioxidant and antimicrobial activities. Furthermore, there were clinical studies undertaken specifically to observe the effect of the oil in addressing cardiovascular challenges in menopausal women and conditions related to sex hormone imbalances. The comprehensive overview covers a wide array of data on the composition and potential uses of pumpkin seed oil.

A Review Article published in 2022 in the journal Nutrients found that Equol, a powerful estrogen-like compound derived from soy, could be key to better health in postmenopausal women if gut microbiome could be altered to facilitate its production. The methodology of this research involved looking closely at the properties and actions of equol, a metabolite of the soy isoflavone daidzein. This substance is produced through the process of intestinal bacterial metabolism, but the ability to produce it is not present in over half of the human population due to the absence of specific equol-producing bacteria in the gastrointestinal tract. Given that the make up of the gut microbiome varies from person to person, understanding the effects of equol and daidzein in the human body has been a complex task. Furthermore, the fact that rodents easily produce equol complicates the matter, as findings from rodent models may not directly apply to humans. While interpreting the results, it was found that equol, due to its strong estrogenic activity, could potentially be an excellent means to manage postmenopausal symptoms and overall health. However, the ability to produce equol varies significantly among people, based on the bacterial microflora of their gut. Therefore, the benefits of equol could potentially be amplified by finding effective methods to manipulate the gut microbiome to foster equol production, a strategy that could lead to improved health outcomes for postmenopausal women.

A Systematic Review published in 2021 in the journal European Journal of Obstetrics & Gynecology and Reproductive Biology found that Phytoestrogens, used in various forms, have shown improvement in urogenital menopause symptoms and improved women's sexual function, promoting overall quality of life. A thorough and systematic review was conducted on databases including PubMed, EMBASE, Web of Science, Cochrane library, Scopus and ProQuest, spanning from the years 2000-2020. The focus was solely on randomized clinical trials. An evaluation of the quality of selected papers was carried out using the CONSORT checklist. In total, 33 high-quality papers were reviewed which discussed the different forms and uses of phytoestrogens. The results of this systematic review reveal that phytoestrogens including Pueraria Mirifica, fennel, Hop plant, Glycine Max, soy, red clover, black cohosh, ginsing, cimicifugaracemosa, genistein, diadzein, glycitein and isoflavone, used as various products such as oral capsules, pills, food supplements, enriched powders, vaginal gels, creams and suppositories, improved menopausal urogenital symptoms. Particularly, the recovery rate was found to be higher when these were applied vaginally. Further implication of these findings is the enhancement of women's sexual function following treatment, validating the use of phytoestrogens as a safe, low-risk and accessible method to alleviate urogenital symptoms.

A Experimental Study published in 2019 in the journal Phytotherapy Research found that Extract of pumpkin seeds displays estrogenic properties, potentially offering a solution to alleviate symptoms of menopausal syndromes resulting from estrogen deficiency. In the study, scientists conduct in vitro analysis using a colorimetric-based assay on kidney cells derived from Chinese hamsters. Furthermore, they perform in vivo experiments involving 7-week old female rats that were specially prepared to model menopausal conditions. These rats are split into differing groups, each receiving a different dosage of pumpkin seed extract. Other observable parameters include uterine weight, condition of mammary glands, serum lipid levels, and bone density measured after a period of 30 days. The researchers also utilize a computer-based technique called molecular docking to investigate how certain active compounds in the pumpkin seed extract respond to estrogen receptors. Separately, this study indicates the pumpkin seed extract's positive impact on uterine weight and mammary gland health in rats, demonstrating properties similar to the hormone 17β-estradiol. Additionally, consumption of the extract led to improved lipid profile - with increased levels of good cholesterol and decreased bad cholesterol- and improved bone density. The study suggests that these beneficial results align with the growth of bone-building cells and decrease in bone-resorbing cells. The digital validation confirms the strength of interactions between active compounds found in the extract and the estrogen receptors.
