Aims Uterine leiomyomas, or fibroids, are estrogen dependent benign tumor in women, however, they have limited treatment options. Simvastatin, a drug commonly used to treat high cholesterol. Recently we demonstrated that simvastatin alters estrogen signaling by reducing the expression and trafficking of the estrogen receptor-α (ER-α) in human uteri...

Background Randomized trials of assisted reproductive technology (ART) have been designed for outcomes of clinical pregnancy or live birth and have not been powered for obstetric outcomes such as preeclampsia, critical for maternal and fetal health. ART increasingly involves frozen embryo transfer (FET). Although there are advantages of FET, multip...

Newer minimally invasive techniques provide treatment options for symptomatic uterine fibroids while allowing uterus preservation. The objective of this review was to analyze the efficacy of uterine-preserving, minimally invasive treatment modalities in reducing fibroid-related bleeding. A comprehensive search was conducted of PubMed, Embase, PsycI...

Background Uterine fibroids are highly prevalent, collagen-rich, mechanically stiff, fibrotic tumors for which new therapeutic options are needed. Increased extracellular matrix (ECM) stiffness activates mechanical signaling and Hippo/YAP promoting fibroid growth, but no prior studies have tested either as a therapeutic target. We tested the hypoth...

Stem cells in the endometrium and myometrium possess an immense regenerative potential which is necessary to maintain the menstrual cycle and support pregnancy. These cells, as well as bone marrow stem cells, have also been implicated in the development of common benign gynecological disorders including leiomyomas, endometriosis and adenomyosis. Cu...

Uterine fibroids feature excessive deposition of types I and III collagen. Previous ex vivo studies showed an FDA-approved collagenase (EN3835)-digested types I and III collagen fibers in fibroid tissues; however, collagenase had not been evaluated in vivo for effects on uterine fibroids. The objective was to assess the safety and tolerability of c...

Objective The aim of this systematic review was to survey and assess modern methodologies used to test oocyte quality that have prognostic value in predicting assisted reproductive technology (ART) outcomes.
