Review
OBJECTIVE
Polycystic ovary syndrome (PCOS) is an endocrine disorder that affects one in every 15 women worldwide. This disorder is mainly characterized by increased levels of male hormones (androgens), acne, and hirsutism, and can lead to long-term insulin resistance, miscarriage, or even infertility in women. PCOS is a disorder that can be treated with natural and allopathic remedies that work against the PCOS mechanism. The present study reviews previous studies on the treatment of PCOS using natural drugs.
METHODS
The data in this study were collected from articles published in reputable databases including ScienceDirect, PubMed, Google Scholar, and SID in the field of medicinal plants from 1990 to 2021.
RESULTS
A review of the literature showed that plants such as aloe vera and chamomile improve fertility by increasing the number of ovarian follicles. Besides, Vitex agnus-castus and octane reduce hirsutism by reducing testosterone and androgen levels. It was also shown that liquorice, ginseng, cinnamon, and de chiro Inositol improve the adverse effects of diabetes caused by PCOS by lowering lipid and blood glucose levels. Moreover, Stachys lavandulifolia and fennel are effective in changing endometrial tissue parameters in PCOS by reducing estrogen and hyperplasia.
CONCLUSIONS
Various studies have shown that herbal medicines can improve PCOS symptoms in women with minimal side effects but a longer treatment cycle.

Review
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women at reproductive age. However, the underlying pathogenic mechanisms have not been completely understood. Hyperandrogenism is an important clinic feature in patients with PCOS, suggesting its pathologic role in the development and progression of PCOS. However, the actual role of androgen and the related signals in PCOS and PCOS-related complications have not yet been clarified. In this review, we surveyed the origin and effects of androgen on PCOS and the related complications, highlighted the cellular signals affecting androgen synthesis and summarized the pathological processes caused by hyperandrogenism. Our review well reveals the important mechanisms referring the pathogenesis of PCOS and provides important clues to the clinic strategies in patients with PCOS.

Review
Androgen excess in women typically presents clinically with hirsutism, acne or androgenic alopecia. In the vast majority of cases, the underlying aetiology is polycystic ovary syndrome (PCOS), a common chronic condition that affects up to 10% of all women. Identification of women with non-PCOS pathology within large cohorts of patients presenting with androgen excess represents a diagnostic challenge for the endocrinologist, and rare pathology including nonclassic congenital adrenal hyperplasia, severe insulin resistance syndromes, Cushing's disease or androgen-secreting tumours of the ovary or adrenal gland may be missed in the absence of a pragmatic screening approach. Detailed clinical history, physical examination and biochemical phenotyping are critical in risk-stratifying women who are at the highest risk of non-PCOS disorders. Red flag features such as rapid onset symptoms, overt virilization, postmenopausal onset or severe biochemical disturbances should prompt investigations for underlying neoplastic pathology, including dynamic testing and imaging where appropriate. This review will outline a proposed diagnostic approach to androgen excess in women, including an introduction to androgen metabolism and provision of a suggested algorithmic strategy to identify non-PCOS pathology according to clinical and biochemical phenotype.

Review
Androgenetic alopecia (AGA) is the most common type of hair loss and features progressive miniaturization of hair follicles. Generally, the occurrence of AGA has long been thought to be driven by genetic and androgen predisposition. However, increasingly, data proposed ageing and AGA are intimately linked. Elevated senescent cell burden and androgen and oxidative stress-induced senescence mechanisms in ageing may be initial targets to improve AGA. This review summarizes the biological links between ageing and AGA, with special focus on cellular senescence. In addition, we discuss the potential therapeutic strategies for improving cellular senescence in AGA, such as inhibiting dermal papilla cells and hair follicle stem cells senescence driven by androgen and reactive oxygen species, removing senescent cell, and reducing senescence-associated secretory phenotype (SASP).

Review
Adequate levels of androgens (eugonadism), and specifically testosterone, are vital compounds for male quality of life, longevity, and positive health outcomes. Testosterone exerts its effects by binding to the androgen receptor, which is expressed in numerous tissues throughout the body. Significant research has been conducted on the impact of this steroid hormone on skeletal, muscle and adipose tissues and on the cardiovascular, immune, and nervous systems. Testosterone levels have also been studied in relation to the impact of diseases, aging, nutrition and the environment on its circulating levels. Conversely, the impact of testosterone on health has also been evaluated with respect to its cardiac and vascular protective effects, body composition, autoimmunity and all-cause mortality. The male aging process results in decreasing testosterone levels over time. The exact mechanisms and impact of these changes in testosterone levels with age on health- and life-span are still not completely clear. Further research is needed to determine the optimal testosterone and androgen levels to protect from chronic age-related conditions such as frailty and osteoporosis.

Review
Postmenopausal hyperandrogenism is a condition caused by relative or absolute androgen excess originating from the ovaries and/or the adrenal glands. Hirsutism, in other words, increased terminal hair growth in androgen-dependent areas of the body, is considered the most effective measure of hyperandrogenism in women. Other symptoms can be acne and androgenic alopecia or the development of virilization, including clitoromegaly. Postmenopausal hyperandrogenism may also be associated with metabolic disorders such as abdominal obesity, insulin resistance, and type 2 diabetes. Mild hyperandrogenic symptoms can be due to relative androgen excess associated with menopausal transition or polycystic ovary syndrome, which is likely the most common cause of postmenopausal hyperandrogenism. Virilizing symptoms, on the other hand, can be caused by ovarian hyperthecosis or an androgen-producing ovarian or adrenal tumor that could be malignant. Determination of serum testosterone, preferably by tandem mass spectrometry, is the first step in the endocrine evaluation, providing important information on the degree of androgen excess. Testosterone >5 nmol/L is associated with virilization and requires prompt investigation to rule out an androgen-producing tumor in the first instance. To localize the source of androgen excess, imaging techniques are used, such as transvaginal ultrasound or magnetic resonance imaging (MRI) for the ovaries and computed tomography and MRI for the adrenals. Bilateral oophorectomy or surgical removal of an adrenal tumor is the main curative treatment and will ultimately lead to a histopathological diagnosis. Mild to moderate symptoms of androgen excess are treated with antiandrogen therapy or specific endocrine therapy depending on diagnosis. This review summarizes the most relevant causes of hyperandrogenism in postmenopausal women and suggests principles for clinical investigation and treatment.

Review
The hair cycle and hair follicle structure are highly affected by various hormones. Androgens-such as testosterone (T); dihydrotestosterone (DHT); and their prohormones, dehydroepiandrosterone sulfate (DHEAS) and androstendione (A)-are the key factors in terminal hair growth. They act on sex-specific areas of the body, converting small, straight, fair vellus hairs into larger darker terminal hairs. They bind to intracellular androgen receptors in the dermal papilla cells of the hair follicle. The majority of hair follicles also require the intracellular enzyme 5-alpha reductase to convert testosterone into DHT. Apart from androgens, the role of other hormones is also currently being researched-e.g., estradiol can significantly alter the hair follicle growth and cycle by binding to estrogen receptors and influencing aromatase activity, which is responsible for converting androgen into estrogen (E2). Progesterone, at the level of the hair follicle, decreases the conversion of testosterone into DHT. The influence of prolactin (PRL) on hair growth has also been intensively investigated, and PRL and PRL receptors were detected in human scalp skin. Our review includes results from many analyses and provides a comprehensive up-to-date understanding of the subject of the effects of hormonal changes on the hair follicle.

Meta-Analysis Review
Androgen Receptor Signaling Inhibitors in Addition to Docetaxel with Androgen Deprivation Therapy for Metastatic Hormone-sensitive Prostate Cancer: A Systematic Review and Meta-analysis.
CONTEXT
Recent randomized controlled trials (RCTs) examined the role of adding androgen receptor signaling inhibitors (ARSIs), including abiraterone acetate (ABI), apalutamide, darolutamide (DAR), and enzalutamide (ENZ), to docetaxel (DOC) and androgen deprivation therapy (ADT) in patients with metastatic hormone-sensitive prostate cancer (mHSPC).
OBJECTIVE
To analyze the oncologic benefit of triplet combination therapies using ARSI + DOC + ADT, and comparing them with available treatment regimens in patients with mHSPC.
EVIDENCE ACQUISITION
Three databases and meetings abstracts were queried in April 2022 for RCTs analyzing patients treated with first-line combination systemic therapy for mHSPC. The primary interests of measure were overall survival (OS) and progression-free survival (PFS). Subgroup analyses were conducted to assess the differential outcomes in patients with low- and high-volume disease as well as de novo and metachronous metastasis.
EVIDENCE SYNTHESIS
Overall, 11 RCTs were included for meta-analyses and network meta-analyses (NMAs). We found that the triplet combinations outperformed DOC + ADT in terms of OS (pooled hazard ratio [HR]: 0.74, 95% confidence interval [CI]: 0.65-0.84) and PFS (pooled HR: 0.49, 95% CI: 0.42-0.58). There was no statistically significant difference between patients with low- and high-volume disease in terms of an OS benefit from adding an ARSI to DOC +ADT (both HR: 0.79; p = 1). Based on NMAs, triplet therapy also outperformed ARSI + ADT in terms of OS (DAR + DOC + ADT: pooled HR: 0.74, 95% CI: 0.55-0.99) and PFS (ABI + DOC + ADT: HR: 0.68, 95% CI: 0.51-0.91, and ENZ + DOC + ADT: HR: 0.70, 95% CI: 0.53-0.93). An analysis of treatment ranking among de novo mHSPC patients showed that triplet therapy had the highest likelihood of improved OS in patients with high-volume disease; however, doublet therapy using ARSI + ADT had the highest likelihood of improved OS in patients with low-volume disease.
CONCLUSIONS
We found that the triplet combination therapy improves survival endpoints in mHSPC patients compared with currently available doublet treatment regimens. Our findings need to be confirmed in further head-to-head trials with longer follow-up and among various patient populations.
PATIENT SUMMARY
Our study suggests that triplet therapy with androgen receptor signaling inhibitor, docetaxel, androgen deprivation therapy prolongs survival in patients with metastatic hormone-sensitive prostate cancer compared with the current standard doublet therapy.

Review
The endocrine system influences all tissues and cells in the human body. The ocular surface is constantly exposed to circulating hormones and expresses their specific receptors. Dry eye disease (DED) is a disorder with multifactorial etiology, and endocrine anomalies are one of the inciting factors. The endocrine anomalies that cause DED include physiological conditions such as menopause, menstrual cycle variations, pathologies such as polycystic ovarian syndrome, androgen resistance, iatrogenic conditions such as contraceptive use, and antiandrogen treatment. This review highlights the status of these hormones in DED along with the mechanism of action of different hormones on the ocular surface structures and the clinical implications of these effects. The influence of androgens, estrogens, and progesterone on the ocular surface tissues, and the implications of androgen-deficient states in DED are also discussed. The physiological and pathological effects of menopause and sex hormone replacement therapy are discussed. The effects of insulin and insulin resistance on the ocular surface and DED, and the growing potential of topical insulin therapeutics for DED are mentioned. Thyroid-associated ophthalmopathy, its impact on the ocular surface, and the tissue effects of thyroid hormone in the context of DED are reviewed. Finally, the potential role of hormonal therapeutics in the management of DED has also been discussed. The compelling evidence suggests that it would be clinically beneficial to consider the possibility of hormonal imbalances and their impact while treating patients with DED.

Randomized Controlled Trial
Liraglutide 3 mg on weight, body composition, and hormonal and metabolic parameters in women with obesity and polycystic ovary syndrome: a randomized placebo-controlled-phase 3 study.
OBJECTIVE
To study the efficacy and safety of the GLP-1 analog liraglutide 3 mg (LIRA 3 mg) vs. placebo (PL) for reduction of body weight (BW) and hyperandrogenism in women with obesity and polycystic ovary syndrome (PCOS).
DESIGN
Randomized, double-blind, placebo-controlled trial.
SETTING
Hospital-based outpatient endocrine and metabolic center.
PATIENT(S)
Women diagnosed with PCOS (NIH criteria) were randomly assigned to LIRA 3 mg (n = 55) or PL (n = 27) once daily for 32 weeks with lifestyle intervention.
INTERVENTION(S)
Study visits at baseline and 32 weeks included BW and body composition by dual-energy x-ray absorptiometry. Oral glucose tolerance tests were done with sex steroids, free androgen index (FAI), and lipids measured in the fasting sample.
MAIN OUTCOME MEASURE(S)
The primary end points were changes in BW and FAI. Safety was assessed in all patients who received at least one dose of the study drug.
RESULT(S)
Change in BW from baseline to week 32 was -5.7% (±0.75) with LIRA 3 mg vs. -1.4% (±1.09) with PL. At week 32, more participants on LIRA 3 mg than on PL achieved at least 5% weight reductions (25 of 44 vs. 5 of 23). Free androgen index significantly reduced with LIRA 3 mg compared with the PL where the mean FAI slightly increased. Gastrointestinal events, which were mostly mild to moderate, were reported in 58.2% of the LIRA 3 mg-subjects and 18.5% of PL subjects.
CONCLUSION(S)
LIRA 3 mg once daily appears superior to PL in reducing BW and androgenicity and improving cardiometabolic parameters in women with PCOS and obesity.
