Despite what the name suggests, Polycystic Ovary Syndrome isn’t just about ovaries—or cysts, for that matter. In fact, many people diagnosed with PCOS don’t have any ovarian cysts at all. Confusing? You’re not alone. The name dates back to how the condition was first described, but science has come a long way since then. Today, we understand that PCOS is really a complex hormonal and metabolic condition that affects far more than reproductive health.
At its core, PCOS is about hormonal imbalance. When key hormones like insulin, androgens (like testosterone), and others are out of sync, they can create a domino effect throughout the body. This hormonal miscommunication can lead to irregular periods, acne, weight changes, hair loss or excess hair growth, difficulty with ovulation or fertility—and that’s just the shortlist. But here’s the thing: PCOS doesn’t follow a single pattern. Some women experience textbook symptoms. Others don’t fit the mold at all. That’s part of what makes PCOS so challenging—and why understanding your unique experience matters.
So, how can the PCOS Association help?
We’re here to offer more than definitions. We’re here to offer direction. Whether you’re newly diagnosed, still searching for answers, or years into your journey and feeling stuck, we’re committed to helping you make sense of PCOS—and make progress.

When we consider the treatment of polycystic ovary syndrome (PCOS), one of our treatment options is metformin, which reduces free testosterone levels in PCOS patients. We were interested to know what happens to the free testosterone levels of male type 2 diabetes mellitus (T2DM) patients when we use metformin. The effect of metformin on testosterone level, fertility, and sexual activity in males has been issues of interest to researchers. This study was conducted to observe the effect of...

CONCLUSION: The low expressions of Xist, MALAT1, and NEAT1 were associated with the high risk of MetS in PCOS patients, with MALAT1 potentially serving as a preferred molecular marker for discriminative MetS in PCOS.

CONCLUSION: These findings suggest that M. spicata and carvone ameliorate metabolic disturbance and ovarian dysfunction in PCOS by suppressing SREBP1/TLR4 expression.

CONCLUSIONS: While several authors have linked respiratory issues and menstrual disturbances, there are no available surveys that investigate the frequency of CRDs in PCOS patients. Despite their qualitative nature, our results sustain previous indications on a possible link between CRDs and PCOS. In future, appropriate studies may elucidate possible etiological mechanisms joining respiratory health to PCOS.

CONCLUSION: Adiposity (measured by BMI)-not dietary inflammation-was independently associated with key PCOS manifestations, demonstrating significant positive relationships with hyperandrogenism markers (FAI, testosterone), insulin resistance (HOMA-IR), and clinical hirsutism. A normal BMI was correlated with clinically meaningful reductions in metabolic-androgen parameters compared to obesity. Thus, weight loss and a generally healthy diet may need to be combined to impact PCOS features...

Background Gestational diabetes mellitus (GDM) is a common metabolic complication of pregnancy associated with significant maternal and fetal morbidity. Early identification of women at risk is essential to improve outcomes. This study evaluated the predictive accuracy of first-trimester biochemical and clinical markers for the early detection of GDM in a South Indian population. Methods A prospective observational study was conducted at a tertiary care hospital in South India over eight months....

CONCLUSIONS: In infertile women, treatment for more than three ovarian stimulation cycles in assisted reproductive technology, tubal lesions and advanced age were factors associated with an accelerated rate of AMH decline, whereas PCOS was associated with a reduced rate of AMH decline. Medical intervention targeting these influencing factors may mitigate the rate of ovarian reserve loss and delay ovarian aging. The results specifically highlight the need for caution regarding the potential...

CONCLUSION: Women with pre-existing reproductive health disorders, such as PCOS and infertility, are more vulnerable to stress and are more likely to experience a decline in AMH level and, by extension, ovarian reserve following stressful experiences.

Reproductive disorders can result from a defective action of the neuropeptide gonadotropin-releasing hormone (GnRH), the master regulator of reproduction. We have previously shown that SELENOT, a newly-described thioredoxin-like selenoprotein highly expressed in endocrine and neuroendocrine cells, plays a role in hormone secretion and neuroprotection. However, whether SELENOT is involved in neuro-endocrine regulations in vivo is totally unknown. We found that SELENOT deficiency in the brain...

CONCLUSION: αvβ3 integrin plays an important role in the development of the window of implantation in obese PCOS individuals. Further research is needed to confirm these results and to identify the potential mechanisms underlying this association.

CONCLUSION: It is recommended that sleep, like diet and exercise, be included in the lifestyle management of PCOS. For this purpose, more clinical studies are needed to prove the connection between improving sleep and reducing disease outcomes.

The dehydroepiandrosterone (DHEA)-induced mouse model is widely used to study polycystic ovary syndrome (PCOS), yet findings on antral follicle (AF) dynamics remain inconsistent. Among 12 representative studies-classified as mechanistic (n = 1), intervention (n = 7), or mixed-type (n = 4)-half reported increased AF counts, while the others reported reductions. This variability likely stems from methodological differences, including DHEA dosage, solvent, animal age, treatment duration, follicle...

Polycystic Ovary Syndrome (PCOS) is a common endocrine condition that affects women of reproductive age. The study used high-throughput sequencing to profile gene expression in PCOS and control samples. The sequenced reads were quality assessed and aligned to the human reference genome hg38 using FastQC and the Hisat2 aligner. The R software "DESeq2" identified 1193 differentially expressed genes (DEGs) in SRP224633 and 82 DEGs in SRP353681. Notably, 8 DEGs were shared by the two datasets, and a...

Prenatally androgenised (PA) sheep are a clinically realistic model of polycystic ovary syndrome (PCOS). They have dysfunctional subcutaneous adipose tissue (SAT) with reduced adipogenesis in adolescence and enlarged adipocytes with increased inflammation in adulthood. We hypothesised that analysis of SAT in young adults, after adipogenesis is complete but before inflammation is apparent, would give insights into the evolution of adipose tissue dysfunction. Pregnant sheep were treated...
