  • Puberty-Associated Gingival Enlargement Exacerbated by Polycystic Ovary Syndrome: A Case Report. [Review]
    J Clin Exp Dent. 2026 Jul; 18(8):e968-e973.Dhalla N, Gopal L, … Pandey RJC
  • CONCLUSIONS: This case highlights that PCOS may contribute to or exacerbate gingival enlargement through hormonal and inflammatory alterations rather than being a direct etiological factor. Early interdisciplinary diagnosis and co-management between dental and medical professionals are crucial for optimizing both periodontal and systemic health outcomes in adolescent patients.
  • Progesterone Induces Production of Reactive Oxygen Species in a Bovine Granulosa Cell Line. [Journal Article]
    Reprod Domest Anim. 2026 Mar; 61(3):e70194.Stassi AF, Cattaneo Moreyra ML, … Rey FRD
  • In cattle, low progesterone (P4) concentrations have been linked to anovulation. To study the local effects of P4 on granulosa cells, in the present study we aimed: (a) to characterise the expression of receptors (progesterone receptor (PR), oestrogen receptors α and β (ERα and β), FSH receptor (FSHR) and LH receptor (LHR)), as well as the co-expression of PR and signal transducer and activator o…
  • Gynecologic Cancers: Endometrial Cancer. [Review]
    FP Essent. 2025 Nov; 558:15-20.Miller A, Paruchuri BFE
  • Postmenopausal vaginal bleeding is reported by 90% of patients with a diagnosis of endometrial cancer. Risk factors for endometrial cancer include obesity, increasing age, type 2 diabetes, use of unopposed estrogen, polycystic ovary syndrome, chronic anovulation, and family history of gynecologic cancers. Evaluation includes a detailed history and physical examination, focusing on bleeding charac…
  • Anovulatory bleeding and the spectrum of bleeding disorders: Understanding heavy menstrual bleeding in adolescents. [Journal Article]
    Int J Gynaecol Obstet. 2026 Apr; 173(1):180-186.Özer E, Akman AÖ, … Gürbüz FIJ
  • CONCLUSIONS: Bleeding disorders should be considered in all adolescents with HMB, particularly when hemoglobin is ≤10 g/dL. Persistent bleeding despite treatment requires re-evaluation, even if initial results are normal, with special attention to platelet dysfunction. Early recognition and prompt initiation of hormonal therapy, especially combined oral contraceptives, effectively reduce hospitalizations, transfusions, and improve quality of life.
  • Unraveling the mechanisms of ovulatory failure in dairy cows: The role of lipid metabolism. [Journal Article]
    Res Vet Sci. 2025 Sep; 193:105806.Gareis NC, Cattaneo-Moreyra ML, … Rey FRV
  • Ovulatory failure in dairy cows can stem from various causes, including the formation of follicular cysts, which disrupt the estrous cycles and extend reproductive intervals, ultimately hindering herd management and reproductive performance. Reproductive dysfunctions are frequently associated with metabolic disorders, commonly observed in these animals. Therefore, this study aimed to evaluate key…
  • The Relationship Between Obesity, Bariatric Surgery, and Infertility: A Systematic Review. [Review]
    Life (Basel). 2025 May 09; 15(5).Voros C, Varthaliti A, … Loutradis DL
  • CONCLUSIONS: Bariatric surgery is a highly effective treatment for increasing fertility and pregnancy outcomes in obese women, particularly those with PCOS. However, rigorous preconception planning, postoperative nutritional monitoring, and multidisciplinary follow-up are required to reduce the related hazards. Future research should concentrate on long-term reproductive outcomes, standardizing fertility assessment criteria, and improving clinical guidelines for managing post-bariatric pregnancies. These findings support the incorporation of bariatric surgery into fertility treatment regimens for obese women, and they may shape future revisions to clinical guidelines on reproductive care following weight loss surgery.
  • The role of short luteal phases on cycle regularity during the perimenopausal transition. [Journal Article]
    Menopause. 2025 Mar 01; 32(3):258-265.Visby Madsen C, Adornetto G, Kirkegaard KM
  • CONCLUSIONS: These findings could suggest that it may not be feasible to utilize the occurrence of short luteal phases in the context of expressing the likelihood of cycle irregularity, length, or anovulation. However, because of the small sample size in this study, the null findings could be due to lack of power. Larger studies would be needed to determine how short luteal phases may be correlated to cycle regularity.
  • Ovarian leukocytes: Association with follicular persistence and cyst formation in dairy cows. [Journal Article]
    J Reprod Immunol. 2024 Sep; 165:104289.Stassi A, Etchevers L, … Ortega HJR
  • One of the initial causes of cystic ovarian disease (COD) is a failure in the normal ovulation mechanism. This study aimed to characterize the populations of immune cells (T-lymphocytes, B-lymphocytes, monocytes-macrophages and granulocytes) present in the ovary of cows with COD and induced follicular persistence, and evaluate their relation with follicular persistence and cyst formation. The fol…
