A lipiodol hysterosalpingogram was the routine test for tubal patency as recently as the 1970s. Observational studies, then randomised controlled trials, provided evidence of a fertility enhancing effect of lipiodol. It has been found to im…

Endometriosis is common in women with infertility but its management is controversial and varied. This article summarises the consensus developed by a group of Australasian subspecialists in reproductive endocrinology and infertility (the A…

INTRODUCTION: About 17% of couples in industrialised countries seek help for infertility, which may be caused by ovulatory failure, tubal damage or endometriosis, or a low sperm count. In developed countries, 80% to 90% of couples attemptin…

BACKGROUND: There have been conflicting results in randomized trials of the effects of laparoscopic uterosacral nerve ablation (LUNA) in chronic pelvic pain. Our objective was to perform a meta-analysis using individual patient data (IPD) t…

Randomised controlled trials are applied more readily to medical than surgical interventions. There are even more barriers to randomised trials of surgical interventions than to other randomised trials. These include reluctance among surgeo…

INTRODUCTION: Ectopic endometrial tissue is found in up to 20% of asymptomatic women, up to 60% of those with dysmenorrhoea, and up to 30% of women with subfertility, with a peak incidence at around 40 years of age. However, symptoms may no…

Objectives This thesis had the following objectives: 1) To assess the existing evidence base for the effectiveness of tubal flushing as a treatment for infertility (Section II, Chapters 4 and 5). 2) To assess current practice and prior beli…

BACKGROUND: Currently, there are a number of clinical trials, but no international collaboration for collating research on effectiveness of laparoscopic uterosacral nerve ablation (LUNA) for alleviating chronic pelvic pain. OBJECTIVE: Meta-…
