Among women of reproductive age, PCOS (polycystic ovarian syndrome) is one of the most prevalent endocrine illnesses. In addition to decreasing female fertility, this condition raises the risk of cardiovascular disease, diabetes, dyslipidemia, obesity, psychiatric disorders and other illnesses. In this paper, we constructed a fractional order model for polycystic ovarian syndrome by using a novel approach with the memory effect of a fractional operator. The study population was divided into four groups for this reason: Women who are at risk for infertility, PCOS sufferers, infertile women receiving therapy (gonadotropin and clomiphene citrate), and improved infertile women. We derived the basic reproductive number, and by utilizing the Jacobian matrix and the Routh-Hurwitz stability criterion, it can be shown that the free and endemic equilibrium points are both locally stable. Using a two-step Lagrange polynomial, solutions were generated in the generalized form of the power law kernel in order to explore the influence of the fractional operator with numerical simulations, which shows the impact of the sickness on women due to the effect of different parameters involved.

Purpose: To compare ovarian function measures in euthyroid women with normogonadotropic anovulation in subclinical hypothyroidism (SCH) or thyroid autoimmunity (TAI) to those without thyroid dysfunction.
Design: A prospective open-label cohort study analyzed anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone, estradiol and testosterone concentrations, ovarian volume, and polycystic ovarian morphology (PCOM) incidence between women with and without SCH or TAI in two study arms: polycystic ovary syndrome (PCOS) and hypothalamic-pituitary-ovarian dysfunction (HPOD).
Results: The prevalence of circulating thyroid peroxidase antibodies (TPOAb) was higher in the PCOS compared to the HPOD arm (p = 0.

American culture encourages overconsumption, fueled by ubiquitous availability and pervasive marketing of ultra-processed foods and other addictive substances. This chronic overindulgence has contributed to rising rates of obesity, type 2 diabetes (T2D), substance abuse, mental health disorders and premature mortality. Glucose-like peptide-1 agonists (GLP-1RAs) affect the brain's reward pathway that mediates addiction to foods and various other substances.

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder associated with insulin resistance (IR) and hyperandrogenism. IR plays a crucial role in the etiology of PCOS. An insulin-sensitizing agent like metformin is most commonly used as an off-label drug for the treatment of PCOS.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder related to multifactors and genetic polymorphisms. Here, we derived an induced pluripotent stem cell (hiPSC) line NTUHi006-A from a phenotype A (full-blown) PCOS patients with clinical hyperandrogenism, chronic anovulation, and polycystic ovarian morphology on ultrasonography. NTUHi006-A showed stemness, pluripotency and stem cell-like morphology.

In this chapter, we explore the multifaceted roles of extracellular vesicles (EVs) in ovarian biology, focusing on their contributions to folliculogenesis, oocyte competence, corpus luteum function, and immune response regulation. EVs, particularly those derived from follicular fluid (ffEVs), are crucial mediators of cell-to-cell communication within the ovarian follicle, influencing processes such as meiotic progression, stress response, and hormonal regulation. We review preexisting literature, highlighting key findings on the molecular cargo of EVs, such as miRNAs and proteins, and their involvement in regulating the function of the follicle cells.
