STUDY QUESTIONS: We aim to produce, disseminate and implement a core outcome set for future infertility research. WHAT IS KNOWN ALREADY: Randomized controlled trials (RCTs) evaluating infertility treatments have reported many different out…

STUDY QUESTION: How well does a previously developed dynamic prediction model perform in an external, geographical validation in terms of predicting the chances of natural conception at various points in time? SUMMARY ANSWER: The dynamic p…

INTRODUCTION: Chronic pelvic pain (CPP) affects more than 1 million UK women with associated healthcare costs of £158 million annually. Current evidence supporting interventions when no underlying pathology is identified is very limited and…

(Abstracted from BJOG 2018;125(1):64–72) The mainstay for the diagnosis and treatment of endometriosis is surgery. After the initial surgery, women often undergo multiple operations in an attempt to alleviate persistent symptoms of pain and…

BACKGROUND: Polycystic ovarian syndrome (PCOS) occurs in 4% to 7% of all women of reproductive age and 50% of women presenting with subfertility. Subfertility affects 15% to 20% of couples trying to conceive. A significant proportion of the…

BACKGROUND: Various methods of conscious sedation and analgesia (CSA) have been used during oocyte retrieval for assisted reproduction. The choice of agent has been influenced by the quality of sedation and analgesia and by concerns about p…

BACKGROUND: Endometriosis is a common cause of chronic pelvic pain which can relapse after surgery, yet little research has been conducted on women's experience of medical treatments for prevention of recurrence and the influence of this on…

Better imaging techniques will result in more women who are undergoing in vitro fertilization (IVF) being diagnosed with adenomyosis. Preliminary data suggest that adenomyosis may have implications for the outcome of IVF. However, available…

BACKGROUND: Gonadotropins are the most commonly used medications for controlled ovarian stimulation in in vitro fertilisation (IVF). However, they are expensive and invasive, and are associated with the risk of ovarian hyperstimulation synd…

BACKGROUND: Endometriosis is a condition with relatively non-specific symptoms, and in some cases a long time elapses from first-symptom presentation to diagnosis. AIM: To develop and test new composite pointers to a diagnosis of endometri…

Abstract Background Endometriosis is associated with the growth of endometrium in ectopic sites mainly within the pelvis. This results in inflammation and scarring, causing pain and impaired quality of life. Endometriotic lesions can be exc…

Chronic pelvic pain (CPP) affects 2.1-24% of women. Frequently, no underlying pathology is identified, and the pain is difficult to manage. Gabapentin is prescribed for CPP despite no robust evidence of efficacy. We performed a pilot trial …

OBJECTIVE: Conduct an economic evaluation based on best currently available evidence comparing alternative treatments levonorgestrel-releasing intrauterine system, depot-medroxyprogesterone acetate, combined oral contraceptive pill (COCP) a…

OBJECTIVE: To develop a prediction model to estimate the chances of a live birth over multiple complete cycles of in vitro fertilisation (IVF) based on a couple's specific characteristics and treatment information. DESIGN: Population based…

OBJECTIVE: To determine pregnancy outcomes in women with endometriosis. DESIGN: A national population based cohort study using record linkage. SETTING: Scotland. PARTICIPANTS: A cohort of 14 655 women followed up over a 30-year period (1…

Chronic pelvic pain (CPP) is common in women of reproductive age and has a significant impact on quality of life, work efficiency and healthcare utilization. CPP can be a manifestation of many different, often multifactorial conditions, and…
