|Abstract:||Background: Obser vational studies suggest higher pregnancy rates after the h ysteroscopic removal of endometrial polyps, submucous ﬁbroids, uterine septum or intrauterine adhe sions, which are detectable in 10% to 15% of women seeking treatment for subfertility. Objectives: To assess the effects of the hysteroscopic removal of endometrial polyps, submucous ﬁbroids, uterine septum or intrauterine adhesions suspected on ul tr asound, hysterosalpingography, diagnostic hysteroscopy or any combination of these methods in women with otherwise unexplained subfertility or prior to intrauterine insemination (IUI), in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). Search methods: We searched the Cochrane Menstrual Disorders and Subfertility Specialised Register (8 September 2014), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2014, Issue 9), MEDLINE (1950 to 12 October 2014), EMBASE (inception to 12 October 2014), CINAHL (inception to 11 October 2014) and other electronic sources of trials including trial registers, sources of unpublished literature and reference l ists. We handsearched the American Society for Reproductive Medicine (ASRM) conference abstracts and proceedings (from January 2013 to October 2014) and we contacted experts in the ﬁe ld. Selection criteria: Randomised comparisons between operative hysteroscopy versus control in women with otherwise unexplained subfertility or under- going IUI, IVF or ICSI and suspected major uterine cavity abnormalities diagnosed by ultrasonography, saline infusion/gel instillation sonography, hysterosalpingography, diagnostic hysteroscopy or any combination of these me thods. Primary outcomes were live birth and h ysteroscopy complications. Secondary outcomes were pregnancy and miscarriage. Data collection and analysis: Two review authors independently assessed studies f or inclusion and risk of bias, and extracted data. We contacted study authors for additional information. Main results: We retrieved 12 randomised trials possibly addressing the research questions. Only two studies (309 women) met the inclusion criteria. Neither reporte d the primary outcomes of live birth or procedure related complications. In women with otherwise unexplained subfertility and submucous ﬁbroids there was no conclusive evidence of a difference between the intervention group treated with hysteroscopic myomectomy and the control group having regular fertility-oriented intercourse during 12 months for the outcome of clinical pregnancy. A l arge clinical beneﬁt with hysteroscopic myomectomy cannot be excluded: if 21% of women with ﬁbroids achieve a clinical pregnancy having timed intercourse only, the evidence suggests th at 39% of women (95% CI 21% to 58%) will achieve a successful outcome following the hysteroscopic removal of the ﬁbroids (odds ratio (OR) 2.44, 95% conﬁdence interval (CI) 0.97 to 6.17, P = 0.06, 94 women, very low quality evidence). There is no evidence of a difference between the comparison groups for the outcome of miscarriage (OR 0.58, 95% CI 0.12 to 2.85, P = 0.50, 30 clinical pregnancies in 94 women, very low quality evi dence). The hysteroscopic removal of polyps prior to IUI can increase the chance of a clinical pregnancy compared to simple diagnostic hysteroscopy and polyp biopsy: if 28% of women achieve a clinical pregnancy with a simple diagnostic hy ste r oscopy, the evidence suggests that 63% of women (95% CI 50% to 76%) will achieve a clinical pregnancy after th e hysteroscopic removal of the endometrial polyps (OR 4.41, 95% CI 2.45 to 7.96, P < 0.00001, 204 women, moderate quality evid e nce). Authors’ conclusions: A large beneﬁt with the hysteroscopic removal of submucous ﬁbroids for improving the chance of clinical pregnancy in women with otherwise unexplained subfertility cannot be excluded. The hysteroscopic removal of e ndometrial polyps suspected on ultrasound in women prior to IUI may increase the clinical pregnancy rate. More randomised studies are needed to substantiate the e ffectiveness of the hysteroscopic removal of suspected endometrial polyps, submucous ﬁbroids, uterine septum or intrauterine adhesions in women with unexplained subfertility or prior to IUI, IVF or ICSI.|
