Given the estrogen-dependence associated with endometriosis, hyper-stimulation associated with assisted reproduction treatment may exacerbate the disease process and adversely affect endometrial receptivity and subsequent implantation. In t…

This chapter includes clinical cases, background, evidence-based practical management options, preventive measures, key-point summaries of endometriotic cysts at oocyte retrieval and answers to questions patients ask. Endometriotic ovarian …

Research questionHow does the number of oocytes used affect the cumulative live birth rate (CLBR) in endometriosis patients who had their oocytes vitrified for fertility preservation?DesignRetrospective observational study including data fr…

Abstract Abstract text The impact of diagnosis endometriosis as part of the Fertility workup Endometriosis is a multifaceted disease that may go from completely asymptomatic to a debilitating condition with severe pelvic pain complicated in…

Endometriosis affects a great proportion of women during their reproductive years and may impair female fertility in several ways. Ovarian endometrioma (OE) is the most frequent phenotype and growing evidence suggest an endometrioma-mediate…

Endometriosis, despite only affecting 10-15% of women of fertile age, is still an enigmatic disease. Recent developments in assisted reproductive technology have contributed to a better understanding of where and how endometriosis could com…

ObjectiveTo describe the outcome of fertility preservation (FP) using vitrified oocytes in patients with endometriosis and to determine the impact of ovarian surgery.DesignRetrospective observational study.SettingUniversity-affiliated priva…

Research questionAvailable evidence shows that the presence of ovarian endometriomas does not interfere with the ovarian response to ovarian stimulation. However, the mean size of the endometriomas in these studies is generally small, and t…

PurposeTo evaluate whether ICSI offers any benefit compared with IVF in different ovarian response categories in case of non-male factor infertility.MethodsThis is a retrospective multicenter analysis using individual patient data, conducte…

BACKGROUND: Endometriosis is known to have an impact on fertility and it is common for women affected by endometriosis to require fertility treatments, including in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI), to im…

This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To determine the effectiveness and safety of long‐term GnRH agonist therapy versus no pretreatment or other pretreatment modalities, (such as long‐term …

PURPOSE OF REVIEW: Surgery has traditionally been the primary treatment option for endometriosis-related infertility of any phenotype. However, advances and refinements of assisted reproductive technologies (ART) permit a more conservative …

Several infertile patients, who may even represent around 40% of the infertile cohort, may respond "suboptimally" (4-9 oocytes retrieved) following IVF, despite being predicted as normal responders. The aim of our longitudinal study was to …

Many women with endometriosis experience compromised fertility. This disease clearly exerts quantitative damage on the ovaries, and perhaps, also qualitative damage. However, it remains controversial whether endometrial receptivity is compr…

Objective To study the degree of interobserver agreement for already known two-dimensional (2D) and three-dimensional (3D) sonography criteria of adenomyosis. Methods Fifty cases (25 adenomyosis cases, 25 non-adenomyosis cases) were studied…

BACKGROUND: Adenomyosis is linked to infertility, but the mechanisms behind this relationship are not clearly established. Similarly, the impact of adenomyosis on ART outcome is not fully understood. Our main objective was to use ultrasound…

Introduction Endometrioma is present in 17% to 40% of women with endometriosis. Since it has been traditionally believed that the presence of an endometrioma adversely affects the outcome of assisted reproductive technology (ART), surgery h…

Endometrial receptivity is still questioned today in women with endometriosis. The aim of this study was to assess the endometrial receptivity gene signature in patients with different stages of endometriosis by investigating transcriptomic…
