Estrogens produced by the ovary play diverse roles in controlling physiological changes in the function of the female reproductive system. Although estradiol acts through classical nuclear receptors, its metabolites (EMs) act by alternative pathways. It has been postulated that EMs act through paracrine-autocrine pathways to regulate key processes involved in normal follicular growth, corpus luteum (CL) development, function, and regression.

- Radiomics can extract hidden information from CT scans, helping to identify if colorectal cancer has already spread to the liver, which can change treatment plans and improve survival rates.
- A new radiomic signature was developed through texture analysis of CT images over 5 years to evaluate colorectal cancer patients for liver metastases.
- The study found that patients who later developed liver metastases had higher levels of hepatic heterogeneity, highlighting the potential of texture analysis in predicting metastasis even when initial scans appear clear.
Study Question: Do alterations in pro- and anti-angiogenic estrogen metabolites in follicular fluid (FF) contribute to the follicular growth arrest and anovulation associated with polycystic ovary syndrome (PCOS)?
Summary Answer: FF of PCOS women with anovulation have reduced levels of pro-angiogenic estrogen metabolites (EMs) and vascular endothelial growth factor (VEGF) compared to that of fertile women with regular menstrual cycles, but exogenous gonadotropins increase the pro-angiogenic EMs and VEGF levels in PCOS women.
What Is Known Already: PCOS is characterized by the arrest of follicular development that leads to chronic anovulation. Follicular arrest is generally associated with elevated plasma levels of luteinizing hormone (LH), androgens and anti-Mullerian hormone (AMH).
