Summary
This study developed a predictive model for diminished ovarian reserve (DOR) in women with Hashimoto
Area of Science:
- Reproductive endocrinology and infertility
- Medical imaging and diagnostics
- Endocrinology and metabolism
Background:
- Hashimoto's thyroiditis (HT) is associated with reproductive health issues.
- Diminished ovarian reserve (DOR) affects fertility in reproductive-aged women.
- Early identification of DOR risk in HT patients is crucial for reproductive management.
Purpose of the Study:
- To develop a predictive model for DOR in reproductive-aged women with HT.
- To integrate transvaginal three-dimensional ultrasound and clinical data for DOR risk assessment.
- To provide a visualized decision-support tool for personalized reproductive health management.
Main Methods:
- Prospective cross-sectional study of 300 reproductive-aged women with HT.
- Transvaginal three-dimensional ultrasound for ovarian volume, blood flow, and antral follicle count (AFC).
- LASSO regression for nomogram construction, validated with ROC curves, calibration curves, and DCA.
Main Results:
- Four independent risk factors identified: pelvic inflammation history, ovarian vascularization index (VI), bilateral AFC, and positive thyroid globulin antibody (TGAb).
- Nomogram achieved high AUC (0.989 training, 0.985 validation) with excellent sensitivity and specificity.
- Strong concordance between predicted and actual DOR probabilities; DCA demonstrated significant net benefit.
Conclusions:
- The developed nomogram accurately predicts DOR risk in women with HT.
- Integration of ultrasound parameters and clinical indicators offers a practical, visualized tool.
- The model supports personalized risk evaluation and reproductive health management for HT patients.

Hypothyroidism II: Pathophysiology
Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
Oogenesis
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
