Deep endometriosis (DE) is considered to be one of the most challenging conditions to manage, especially when it invades surrounding organs like the rectum. Surgical excision of deep rectovaginal endometriosis is required when lesions are s…

Approximately 10% of cancers occur in women under 45 years of age. Chemotherapy, radiotherapy, and bone marrow transplantation cure more than 90% of cancer in women, but can result in premature ovarian insufficiency depending on follicular …

OBJECTIVE: To compare the efficacy of a selective progesterone receptor modulator, ulipristal acetate, and a gonadotropin-releasing hormone antagonist, linzagolix, in a case of severe uterine adenomyosis. DESIGN: Case report. SETTING: Pri…

INTRODUCTION: Linzagolix is a new, investigational, non-peptide, GnRH receptor antagonist being developed to treat endometriosis-associated pain (EAP). The EDELWEISS trial was a Phase 2b, double-blind, randomized, placebo-controlled, multic…

(1) Background: Ovarian tissue transplantation with adipose tissue-derived stem cells (ASCs) has been shown to enhance graft vascularization and increase follicle survival after a short interval of 7 days. The aim of the present study was t…

INTRODUCTION: Linzagolix is a new investigational, non-peptide, oral GnRH receptor antagonist being developed to treat endometriosis-associated pain (EAP). The EDELWEISS trial was a Phase 2b, double-blind, randomized, placebo-controlled, mu…

OBJECTIVE: To study the effect of a new investigational oral gonadotropin-releasing hormone antagonist, linzagolix, on endometriosis-associated pain (EAP). DESIGN: A multinational, parallel group, randomized, placebo-controlled, double-bli…

BACKGROUND: The objective of this review is to determine the evidence or, conversely, the absence of evidence regarding the effectiveness of progestogens in treating premenopausal women with uterine fibroids. In particular, the goal is to a…

Like endometriosis, uterine adenomyosis is another enigmatic disease and remains a source of controversy. Uterine adenomyosis is characterized by the presence of endometrial glands in the myometrium. Two main theories may explain its pathog…

OBJECTIVE: To study the mechanisms of invasion and innervation of deep endometriosis in women. DESIGN: Morphologic and immunohistochemical analysis of human endometriotic lesions. SETTING: Academic research unit. PATIENT(S): Seventeen bi…

Endometriosis is a benign, estrogen-dependent gynecological disorder. It is now well established that three different forms of endometriosis can occur in the pelvic cavity, namely peritoneal endometriosis, ovarian endometriosis and deep end…

Adenomyosis is a commonly diagnosed estrogen-dependent gynecological disorder that causes pelvic pain, abnormal uterine bleeding, and infertility. Despite its prevalence and severity of symptoms, its pathogenesis and etiology have not yet b…

STUDY QUESTION: Is transplantation of cryopreserved ovarian tissue from patients with borderline ovarian tumors (BOTs) a safe procedure? SUMMARY ANSWER: BOT cells were found in frozen-thawed and xenografted ovarian tissue in 1 of 11 BOT pa…

OBJECTIVE: To identify metabolites that are associated with and predict the presence of endometriosis. DESIGN: Metabolomics study using state-of-the-art mass spectrometry approaches. SETTING: University hospital and universities. PATIENT…

OBJECTIVE: To evaluate gynecological and obstetrical outcomes, as well as remaining myometrial thickness, after laparoscopic repair of a cesarean scar. DESIGN: Observational study and prospective evaluation of the remaining myometrium befo…

OBJECTIVE: To evaluate deep nodular endometriotic lesions induced in baboons over 12 months and analyze collective cell migration and nerve fiber density. DESIGN: Morphologic and immunohistochemical analysis of endometriotic lesions induce…

Deep endometriosis remains a source of controversy. A number of theories may explain its pathogenesis and many arguments support the hypothesis that genetic or epigenetic changes are a prerequisite for development of lesions into deep endom…

Endometriosis remains a very enigmatic and perplexing disease. The exact mechanism by which endometriosis causes infertility is still unclear. In the present paper, we will review possible mechanisms leading to subfertility or infertility i…
