Polycystic ovary syndrome (PCOS) is a complex metabolic disorder with unclear etiopathogenesis. It is characterized by heterogeneity in phenotypic manifestations, with the clinical phenotype of PCOS being more severe due to urban, sedentary environments. Environmental factors, including diet, environmental pollutants, genetics, gut dysbiosis, neuroendocrine alterations, and obesity, are among the risk factors that predispose women to PCOS.
The three main components of the etiology of PCOS include genetic, epigenetic, and environmental factors. Diet is considered one of the foremost environmental determinants for the occurrence of PCOS, with hormone levels imbalanced among women with PCOS. Other environmental factors include environmental toxins, diet and nutrition, socioeconomic status, and geography. Hormonal disturbances are also associated with PCOS.
Postnatal exposure to lifestyle and environmental factors, such as poor-quality diet and advanced glycation end products, may activate epigenetically programmed pathways that further contribute to PCOS. Both genetic predispositions for hyperandrogenism and prenatal androgen exposure, an environmental influence, could contribute to PCOS.
Results point to PCOS having a multigenetic basis, being transmitted across generations, and being influenced by environmental variables. Hormonal imbalances, combined with different combinations of multiple gene polymorphisms and environmental factors, explain the heterogeneity of PCOS.
In conclusion, the etiology, prevalence, and modulation of PCOS are complex and multifaceted. Factors such as diet, environmental pollutants, genetics, gut dysbiosis, neuroendocrine alterations, and obesity play significant roles in the development of PCOS.

What influences PCOS?
Polycystic ovary syndrome (PCOS) is a condition characterized by irregular menstrual cycles due to high levels of male hormones called androgens. The exact cause of PCOS is unknown, but genetics, obesity, and other factors, such as high androgen levels, play a role. Treatments for PCOS can include hormonal birth control, insulin-sensitizing medicine, medications to block androgens, and lifestyle changes.
For those who don’t plan to become pregnant, treatments include hormonal birth control, insulin-sensitizing medicine, medications to block androgens, and lifestyle changes. Hormonal birth control helps regulate menstrual cycles and may also improve acne and hair growth. Insulin-sensitizing medicine, such as Metformin, helps the body process insulin, improving menstrual cycles.
For those who want to become pregnant, treatments include drugs to induce ovulation, such as clomiphene and letrozole or gonadotropins. Surgery can restore ovulation by removing tissue in the ovaries that produces androgen hormones. In vitro fertilization (IVF) is an option for those who don’t respond to medication, where the egg is fertilized with the partner’s sperm in a lab before being transferred to the uterus.

What environmental factors affect PCOS?
PCOS is an autoimmune disorder characterized by the production of hormones, including androgens and estrogens, which can lead to a range of health issues. The exact cause of PCOS is not fully understood, but it is believed to involve genetic, environmental, dietary, and metabolic factors. The syndrome’s origins can be traced back to early life in the mother’s womb, and environmental insults and lifestyle issues can affect vulnerable women. Diet is a major environmental determinant, with imbalanced hormone levels in women with PCOS.
High androgen concentrations can significantly impact female reproductive development and function. PCOS is an ancient human disease that has continued through human evolution. A report indicates that women with PCOS have higher levels of anti-mullerian hormone (AMH), which is a good indicator of infertility and PCOS. Additionally, women with PCOS have significantly higher levels of serum AMH compared to controls.
AMH is strongly associated with reproductive, metabolic, and endocrine impairments in PCOS patients. It also has an inhibitory function in follicular growth and recruitment. The preventive action of AMH contributes to hyperandrogenism, which further increases insulin resistance in women with PCOS. Elevated serum AMH levels may indicate poor treatment response, such as weight loss, ovulation induction, and laparoscopic ovarian drilling, while improvement in other clinical parameters is related to declining levels.
What triggers PCOS?
The precise etiology of polycystic ovary syndrome (PCOS) remains uncertain, although a hereditary predisposition is frequently observed. Abnormal hormone levels, including elevated insulin levels, have been identified as a potential contributing factor. A considerable number of women with PCOS exhibit insulin resistance, which results in elevated insulin levels to counteract this resistance. This phenomenon leads to increased hormone activity, including that of testosterone.
Does anything trigger PCOS?
Research indicates that PCOS is influenced by genetic and environmental factors, but its exact cause remains unknown. Recent studies suggest 19 possible gene variants can increase a person’s risk of developing the condition, explaining the differences in symptoms between individuals. Although traditionally associated with the ovaries, these variants have been found in both males and females, with males experiencing similar cardiac and metabolic symptoms to females with PCOS.
Does climate affect PCOS?
Genetic and lifestyle factors have been linked to PCOS, but new evidence suggests environmental pollutants may also play a significant role in its development and pathophysiology.

What environmental toxins cause PCOS?
The administration of plasticizers in animal models has been demonstrated to induce a phenotype analogous to that observed in patients with polycystic ovarian syndrome (PCOS). Furthermore, exposure to endocrine-disrupting chemicals (EDCs) such as phthalates and bisphenol A (BPA) has been linked to adverse health outcomes in the parental generation (F0) and up to the third generation (F3).
What are the factors responsible for PCOS?
Polycystic ovary syndrome (PCOS) is a hormonal issue that occurs during the reproductive years, causing irregular periods, prolonged periods, and excessive androgen levels. The condition is caused by insulin resistance, low-grade inflammation, and genetic factors. PCOS also results in the development of cysts along the outer edge of the ovary, filled with immature eggs called follicles. These follicles fail to release eggs regularly. The exact cause of PCOS is unknown, but early diagnosis and treatment, along with weight loss, may reduce the risk of long-term complications like type 2 diabetes and heart disease.

What is the hidden cause of PCOS?
Hidden PCOS is a simpler form of PCOS that takes three to four months to resolve. Causes include thyroid disease, iodine deficiency, vegetarian diet, and artificial sweeteners. If natural treatments don’t work, consult a doctor for more information. Symptoms usually develop during the first period of a woman, but if they develop later, consult a doctor. Symptoms usually appear during the first period, and if they persist, seek medical help.
Does weather affect PCOS?
The study aimed to evaluate the relationship between the incidence of patients with polycystic ovary syndrome (PCOS) at high risk for ovarian hyperstimulation syndrome (OHSS) after oocyte retrieval and seasonal temperature changes, with extreme climates showing a significantly higher risk. Seasonal changes are closely related to the development of many diseases, such as acute coronary syndromes, infectious and respiratory diseases, and OHSS.
OHSS is a severe complication of controlled ovarian hyperstimulation and is associated with inflammatory factors such as interleukin (IL)-6, tumor necrosis factor (TNF)-α, IL-8, vascular endothelial growth factor, and the local renin-angiotensin aldosterone system.
The immune system changes significantly throughout the year, with serum concentrations of IL-6 and soluble IL-6 receptor showing seasonality with higher expression during cold climates. Extreme weather activates the hypothalamic-pituitary-adrenocortical (HPA) axis and the sympathetic nervous system, resulting in a high level of aldosterone. Abnormal expression of aldosterone promotes renal tubular reabsorption and increases the levels of inflammatory mediators, both of which play a key role in the occurrence of OHSS.
The prediction model had favorable predictive performance and clinical application value, providing a new strategy to reduce the incidence of OHSS.
