Background: Treatment of advanced stages and recurrent ovarian granulosa cell tumors, has not been established yet. The effectiveness of radiation therapy could not be proven. Systemic chemotherapy has shown promising results, but with severe side effects and high incidence of relapse.
Case Reports: We report of one patient with advanced stage III C, and one patient with bulky recurrent ovarian granulosa cell tumors. Both patients were treated with a combination of surgical debulking, Continuous Intraoperative Intraperitoneal Hyperthermic Chemoperfusion (CIIPHCP) with Cisplatin and one of them with adjuvant systemic chemotherapy.
Conclusion: CIIPHCP appears to offer a promising procedure in addition to surgical debulking and systemic chemotherapy for treatment of advanced or recurrent ovarian granulosa cell tumors. The present report is the first concerning the question of adding Intraoperative Hyperthermic Chemoperfusion in the treatment of advanced or recurrent ovarian granulosa cell tumors.

Study Question: Is elevated plasma molybdenum level associated with increased risk for idiopathic premature ovarian insufficiency (POI)?
Summary Answer: Elevated plasma molybdenum level is associated with an increased risk of idiopathic POI through vascular endothelial injury and inhibition of granulosa cell proliferation.
What Is Known Already: Excessive molybdenum exposure has been associated with ovarian oxidative stress in animals but its role in the development of POI remains unknown.
Study Design, Size, Duration: Case-control study of 30 women with idiopathic POI and 31 controls enrolled from August 2018 to May 2019.

Introduction: Identifying non-invasive biomarkers which can predict the outcome of intracytoplasmic sperm injection (ICSI) is crucial, particularly in Germany where the challenges are intensified by the Embryo Protection Act. Recent research has highlighted biomarkers within the epidermal growth factor (EGF) family as central to follicular processes, although their predictive utility remains a subject of debate in the literature. Therefore, the primary objective of this study was to investigate the significance of amphiregulin concentrations in follicular fluid and gene expression in mural granulosa cells on oocyte maturation, fertilization, and embryo quality.

The healthy and orderly development of ovarian follicles is the basic premise to maintain normal and continuous egg production of chickens. Emerging researches continue to reveal the crucial functions of circular RNAs (circRNAs) involved in follicle development. In the present study, a novel circular RNA WRNIP1 (circWRNIP1) with higher abundance in healthy follicles than in atretic follicles was identified, suggesting its important regulatory role in follicle selection and maturation.

This study investigated whether luteinizing hormone receptor (LHR) expression varies in the granulosa cells of individual follicles according to the maturation stage of the oocytes harvested for assisted reproductive technology (ART) treatment. We observed minimal to no LHR mRNA and protein expression in cumulus cells surrounding oocytes arrested in the germinal vesicle (GV) stage. Interestingly, their ability to mature was confirmed by rescue in vitro maturation, suggesting somatic cell LHR deficiency as a key factor for the retrieval of GV oocytes in ART procedures.

Anti-Müllerian hormone (AMH) plays an important role in avian ovarian follicle development. The high mRNA expression of AMH in avian ovarian prehierarchical follicles helps prevent premature granulosa cell differentiation. Vitamin D3 was reported to downregulate AMH mRNA expression in granulosa cells of prehierarchical follicles in hens; however, the underlying molecular mechanism remains unknown.
