This article contains findings obtained from research on animals:
- The results from animal research studies should not be directly applied to humans and the results may not generalise to the human population.
- There may be significant differences between species in terms of physiology, physiology, and pharmacology, as well as differences in the way diseases and treatments are modelled in animals.
- Any conclusions drawn from animal research should be considered with caution and in the context of other types of research studies such as observational studies, clinical trials, and reviews of the literature.

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.

Animal Study Bacillus Gut Microbiota Menopause
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.
