OBJECTIVE: To determine the future priorities for ectopic pregnancy research. DESIGN: Potential research questions were collated from an initial international survey, a systematic review of clinical practice guidelines, and Cochrane system…

OBJECTIVE: To evaluate the presence of Fusobacterium spp. and Fusobacterium nucleatum in eutopic endometrial samples from women with endometriosis compared with controls, and assess their association with the disease. DESIGN: Retrospective…

Endometriosis is a chronic, complex disease for which there are vast disparities in diagnosis and treatment between sociodemographic groups. Clinical presentation of endometriosis can vary from asymptomatic disease-often identified during (…

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…

BACKGROUND: Given no consensus in the literature, this study sought to determine if a protocol of measuring serum estradiol and progesterone the day prior to frozen embryo transfer (FET) improves likelihood of pregnancy and livebirth. METH…

STUDY QUESTION: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting? SUMMARY ANSWER: Consensus definitions for individual core outcomes, contextual sta…

OBJECTIVE: Endometriosis is a chronic, estrogen dependent condition that affects 5-10% of reproductive aged women and is associated with pelvic pain and infertility. As the approach to therapy shifts from surgical ablation to pharmacologica…

OBJECTIVE: To determine whether live birth rates differ by type of endometrial preparation in frozen embryo transfer (FET) cycles. DESIGN: Retrospective cohort study. SETTING: Academic fertility center. PATIENT(S): Reproductive-aged wome…

OBJECTIVE: To assess the impact of endometriosis, alone or in combination with other infertility diagnoses, on IVF outcomes. DESIGN: Population-based retrospective cohort study of cycles from the Society for Assisted Reproductive Technolog…

Interrogating the association between assisted reproductive technologies (ART) and perinatal outcome is complicated but very important. This is an introduction to a series of articles that review this potential association with an eye towar…

A biomarker can be used for early diagnosis of a disease, identification of individuals for disease prevention, as a potential drug target, or as a potential marker for a drug response. A biomarker may also limit the use of drug (and theref…

OBJECTIVE: To evaluate the performance of a novel biomarker, a disintegrin and metalloprotease-12 (ADAM-12), to differentiate an ectopic pregnancy (EP) from normal intrauterine pregnancies (IUPs). DESIGN: Case-control study. SETTING: Thre…

There is a great need for biomarkers that can serve as surrogates for important clinical endpoints such as endometriosis. The pursuit of a marker has been hampered by disparate study designs, small samples, and controversy regarding desired…

OBJECTIVE: To study the association of perinatal outcome and IVF transfer type in a group of infertility patients with standardized treatment and similar prognosis. DESIGN: Retrospective cohort study. SETTING: University-based infertility…

OBJECTIVE: To identify potential novel biomarkers that differ between subjects with and without endometriosis and that might aid in developing a noninvasive, serum-based diagnostic test. DESIGN: Case-control evaluation of a diagnostic test…

The objective of this case-control study of 242 reproductive-age women was to determine the concentration of afamin in the serum and peritoneal fluid of women with and without endometriosis and to test afamin as a diagnostic marker of endom…
