Estrogens play an important role throughout a woman's life; therefore, disrupting their physiological production will alter hormonal balance with consequences for estrogen-related conditions, such as endometriosis and adenomyosis. The gut m…

OBJECTIVE: To study the role of PGE2 in regulating plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (tPA) in human primary endometrial endothelial cells (HEECs) from women with normal menstrual bleeding (NMB) and h…

Abstract With the aim to shorten the time for diagnosis and accelerate access to correct management, a non-invasive diagnostic test for endometriosis was developed and validated. The IVD test combines an ELISA test kit to quantify CA125 and…

Bleeding irregularities are one of the major reasons for discontinuation of oral contraceptives (OCs), and therefore clinicians need to set expectations during consultations. In this review we provide an overview of bleeding data of recentl…

OBJECTIVES: To describe ovulation inhibition and safety of daily oral ulipristal acetate (UPA) over 84 days. STUDY DESIGN: This multi-center phase 1 and/or 2 trial randomized participants to use oral ulipristal 10 mg or 5 mg daily or a 3 c…

OBJECTIVE: To determine if coexisting adenomyosis limits the efficacy of elagolix, an oral gonadotropin-releasing hormone antagonist, with hormonal add-back therapy in reducing heavy menstrual bleeding in women with uterine fibroids. DESIG…

OBJECTIVE: In this post hoc analysis, we evaluated the impact of elagolix on dysmenorrhea and nonmenstrual pelvic pain across menstrual period (bleeding days) and nonmenstrual (nonbleeding) days. METHODS: Data from two randomized, 6-month,…

As a key mechanism in fibrinolysis and tissue remodeling, the plasminogen activator system has been suggested in the process of endometrial shedding and tissue remodeling. Previous studies have explored the role of estrogen, progesterone, a…

While the most common symptom associated with endometriosis is pelvic pain, the systemic manifestations of the disease and the accompanying adverse psychological, emotional, social, familial, sexual, educational and workplace effects are in…

Objectives: The objective was to evaluate the effects of elagolix on dyspareunia in women with endometriosis-associated pain. Methods: Data were pooled from two similar, randomized, double-blind, placebo-controlled, 6-month phase 3 studies …

CONTEXT: Elagolix is an oral gonadotropin-releasing hormone (GnRH) antagonist recently approved for the treatment of endometriosis-associated pain and being developed for heavy menstrual bleeding associated with uterine fibroids. OBJECTIVE…

OBJECTIVE: To evaluate elagolix, an oral gonadotropin-releasing hormone receptor antagonist, alone or with add-back therapy, in premenopausal women with heavy menstrual bleeding (greater than 80 mL per month) associated with uterine leiomyo…

INTRODUCTION: To evaluate the long-term effect of elagolix, an oral, non-peptide GnRH antagonist, on bone mineral density (BMD) in two 6-month (M) extension studies (Elaris EM-III and IV) of the pivotal, 6M, phase 3 studies (12M overall tre…

OBJECTIVE: To evaluate the efficacy and safety of elagolix, an oral, nonpeptide gonadotropin-releasing hormone antagonist, over 12 months in women with endometriosis-associated pain. METHODS: Elaris Endometriosis (EM)-III and -IV were exte…

Heavy menstrual bleeding (HMB) is a common gynecological problem that has a significant impact on a woman's quality of life and the activities of daily living. Due to the difficulty in accurately describing menstrual bleeding abnormalities …

BACKGROUND: Endometriosis is a chronic, estrogen-dependent condition that causes dysmenorrhea and pelvic pain. Elagolix, an oral, nonpeptide, gonadotropin-releasing hormone (GnRH) antagonist, produced partial to nearly full estrogen suppres…

This review compares the histologic changes that occur in the endometrium following ovulation and progesterone secretion with contraceptive progestins and progesterone receptor modulators (PRMs) that may be used as contraceptive agents in w…

OBJECTIVE: Treatment of menopausal symptoms by compounds with tissue-selective estrogen agonist/antagonist effects, often called selective estrogen receptor modulators, has been researched as an alternative to the use of estrogen therapy. T…
