Abstract

Background: Polycystic Ovary Syndrome (PCOS) is a common gynecological, endocrine, and metabolic disorder of unknown etiology. It is a complex endocrine illness that is marked by reduced development of follicles, hyperandrogenemia, insulin resistivity, infertility, increased luteinizing hormone, obesity, and augmented cystic ovaries.

Objective: This review aimed to assess the efficacy of herbal and bioactive components of medicinal plants for mitigating PCOS.

Materials and Methods: To conduct this review, keywords like “herbal treatment”, “ayurvedic treatment”, “bioactive components of medicinal plants”, “polycystic ovary syndrome”, and “PCOS” were used to search for various articles in search engines such as Google Scholar, PubMed/MEDLINE, Web of Science, Scopus, Elsevier from 1992 to 2023.

Results: More than 28 relevant studies were found and were briefly described in this review. According to the evidence, medicinal plant extracts containing phytoestrogens and these herbal treatments in animal models of PCOS were used to decrease hyperandrogenism, restoration of abnormalities in serum sex steroid profile, ratio of LH: FSH, steroidogenic enzymes, cardiovascular parameters, insulin resistance, ovary weight, lipid profile, and estrous cycles.

Conclusion: The results of this review revealed the variability and efficacy of phytoestrogen activity and herbal treatments associated with PCOS disorder which can be partly effective. These findings may represent an opportunity to investigate and discover new bioactive components of medicinal plants which may help future studies on the etiology, pathophysiology and treatment of PCOS disorder.

Introduction

Polycystic Ovarian Syndrome is a common reproductive, endocrine and metabolic disorder of unknown etiology that was first described in 1935 by Stein and Laventhel, with a preponderance ranging from 8.7% to 21% [1] in women of the reproductive age. According to the Rotterdam criteria, the prevalence of PCOS is 10%, while the prevalence of polycystic ovaries is 28% [28]. Many works of literature suggested that PCOS phenotype may vary widely and is most commonly observed in the post-pubertal period. Many studies suggested that the happening of PCOS is relatively higher among Asian women (52%) than among Western Caucasian women (20-25%) [2]. According to World Health Organization (WHO), PCOS affects 116 million women (4%-12%) globally in 2012, and in 2020, its ratio increased abruptly to 26% [2]. Experts claim that in India 10% of women are affected by PCOS [3]. Hyperandrogenism, polycystic ovaries, and gonadotropin abnormalities are the three main phenotypic characteristics of PCOS. Classical structure of PCOS shows thickening of ovarian cortical, numerous small follicular cysts, hyperplasia, luteinized inner theca, stromal hyperplasia, and numerous immature follicles, an indication of a halting of folliculogenesis. Ovary sizes varies from normal to very large size (volume increases >10cm). In ultrasound, histological detections appear as a peripheral ring of small follicles (610mm in diameter) [4]. Abnormalities in biochemical parameters of PCOS are characterized by elevated serum concentrations of androgenic hormones. In vivo and in vitro studies on theca cells suggested that ovarian theca cells produce androgen in response to Luteinizing Hormone (LH); therefore the blood levels of androgen increase in people with PCOS [5]. The high levels of androgens especially testosterone in PCOS, their role in lack of ovulation, and disrupted synthesis of sex hormones, which causes clinical symptoms and dysfunction of the genital tract in the patients, are the main reasons for infertility in reproductive age women [6,7]. The pathophysiological study of PCOS is distinguished by primary faults in the hypothalamic-pituitary-gonadal -axis, resulting in a variety of metabolic abnormalities such as production of excessive ovarian androgen, ovarian dysfunction, and insulin resistance. PCOS is extensively associated with gonadotropin secretion irregularities, increased steroid hormone secretion, and a high level of LH/FSH ratio, resulting into increase in androgen synthesis and prevents development of normal follicle. A lot of findings suggest that increased oxidative stress contributes in the pathophysiology of PCOS, resulting in difficulties such as chronic inflammation, disrupted follicular development, altered steroidogenesis in the ovaries, hyperandrogenemia, infertility and insulin resistance [8]. Again the histopathological features of PCOS include the following changes in the ovarian tissues: enlarged, sclerotic, numerous cyst follicles, whole ovarian hypertrophy, and thickened capsule >100μm, multiple numbers of sub capsular follicular cysts, albicantia, hyperplasia and premature luteinization of theca cells [2]. Diagnosis of PCOS is currently based on the criteria of the ESRHE/ASRM Rotterdam Consensus meeting in 2003. This criteria suggests that ultrasound of polycystic ovaries along with an ovulation and hyperandrogenism, which widened the previous classification of NIH, 1990 i.e., PCOS should consist hyperandrogenism, an ovulation [9]. The Androgen Excess Society (AES) set up a committee of experts to review all the data published on PCOS to simplify diagnosis in 2006 [10]. The first clinical manifestation of PCOS is present in adolescence. Again, PCOS can be also associated with obesity, insulin resistance (found in 60%-80% of women with PCOS), hyperinsulinemia, and type-2 diabetes mellitus. Apart from this, PCOS can also be associated with psychological disorders including anxiety, bipolar disorder, clinical depression and other mental illness. Ayurveda suggests PCOS to be a “kapha” predominant disorder; where “kapha” is irritated by consumption of more “kapavardhak” and “sneha” consists of “Ahara” and by inactive lifestyle [11].

Herbal medicines, a popular type of Complementary Medicine (CM) are known to contain pharmacologically active components with physiological effects on female reproductive system. According to literature findings, they have been positively related with reduces cases of cardiovascular disease, breast cancer, and osteoporosis in female. Oral Contraceptive Pills (OCP) and Clomiphene Citrate are widely used in pharmaceutical treatment for menstrual irregularities and ovulation induction in females respectively. Metformin, an anti-androgen and hypoglycemic pharmaceutical which is widely used in management for hyperandrogenism. Though it has improved effectiveness on insulin sensitivity and hyperandrogenism, but it shows adverse effects including vomiting, nausea, and gastrointestinal disturbances.

Herbal medicine has the potential for synergistic and antagonistic interactions between compounds [12]. The rationale of this review was to identify herbal medicines with specific reproductive endocrinological effects in PCOS, oligo/amenorrhoea and hyperandrogenism.

Methods and Materials

A comprehensive search was conducted using literature search of English language studies in electronic databases such as Web of Science, PubMed/MEDLINE, Elsevier, SCOPUS and Google databases from 1992 to 2023 in order to regain clinical studies on herbal remedies for PCOS. Keywords like" polycystic ovary syndrome", and "PCOS", herbal treatment", "ayurvedic treatment", "bioactive components of medicinal plants" were used to conduct this review. Search was conducted for all animal studies related to PCOS, pre-clinical and clinical studies which are explaining the ameliorative effect of herbal extracts on PCOS. In addition manually searching of bibliography of review articles have been done.

Result

Numerous studies on the etiology and pathophysiology of PCOS have been done. Again, various common, traditional herbal and non-chemical treatments of PCOS have been also studied. Most of the studies reveal that they can partially improve metabolic dysfunction and abnormalities of certain hormones. So this can be considered as an effective way for prevention and treatment of PCOS by targeting the factors involved in the disorder.

Conclusion

PCOS is one of the most common gynecological disorders of reproductive age. Herbal treatment of PCOS provides a consistent impact with few adverse effects. This review comprises of the evidence for mechanisms of effect for herbal medicine in PCOS, oligo/amenorrhea and hyperandrogenism. It includes 13 preclinical laboratory based and clinical trials. Clinical investigations found no adverse effects for the herbal medicines included in the Table 1. The evidence for Caesalpinia crista and Vitex negundo in the treatment of infertility and oligo/amenorrhea is variable. Asparagus racemosus and Cinnamon are for improving metabolic hormones in PCOS. Fennel, Welsh onions are for increased serum concentration of FSH in PCOS. These herbal medicines not only prevent but also help in healing of ovarian cysts. So, these herbal medicines may present an opportunity to investigate and discover new bioactive components which may help future studies on the etiology and treatment of PCOS disorders.
