BACKGROUND The influence of fibroids on fertility is poorly understood. Submucosal and intramural fibroids that distort the endometrial cavity have been associated with decreased pregnancy rates (PRs) following IVF treatment. However, there is uncertainty about the effect of intramural fibroids that do not distort the endometrial cavity on IVF outcomes. METHODS We conducted a systematic review and meta-analysis of studies to evaluate the association between non-cavity-distorting intramural fibroids and IVF outcome. Searches were conducted on MEDLINE, EMBASE, Cochrane Library and Web of Science. Study selection and data extraction were conducted independently by two reviewers. The Newcastle-Ottawa Quality Assessment Scales were used for quality assessment. Meta-analysis was performed if appropriate. RESULTS We identified 19 observational studies comprising 6087 IVF cycles. Meta-analysis of these studies showed a significant decrease in the live birth (RR = 0.79, 95% CI: 0.70-0.88, P < 0.0001) and clinical PRs (RR = 0.85, 95% CI: 0.77-0.94, P = 0.002) in women with non-cavity-distorting intramural fibroids compared with those without fibroids, following IVF treatment. CONCLUSION The presence of non-cavity-distorting intramural fibroids is associated with adverse pregnancy outcomes in women undergoing IVF treatment.

There is conflicting evidence regarding the effect of raised body mass index (BMI) on the outcome of assisted reproductive technology. In particular, there is insufficient evidence to describe the effect of BMI on live birth rates. We carried out a systematic review and meta-analysis of studies to evaluate the effect of raised BMI on treatment outcome following IVF/ICSI treatment. Subgroup analysis on overweight and obese patients was performed. Literature searches were conducted on MEDLINE, EMBASE and the Web of Science from 1966 to 2010. Thirty-three studies including 47,967 treatment cycles were included. Results indicated that women who were overweight or obese (BMI ≥ 25) had significantly lower clinical pregnancy (RR=0.90, P<0.0001) and live birth rates (RR=0.84, P=0.0002) and significantly higher miscarriage rate (RR=1.31, P < 0.0001) compared to women with a BMI < 25 following treatment. A subgroup analysis of overweight women (BMI ≥ 25-29.9) revealed lower clinical pregnancy (RR=0.91, P=0.0003) and live birth rates (RR=0.91, P=0.01) and higher miscarriage rate (RR=1.24, P < 0.00001) compared to women with normal weight (BMI < 25). In conclusion, raised BMI is associated with adverse pregnancy outcome in women undergoing IVF/ICSI treatment, including lower live birth rates. This effect is present in overweight as well as obese women.

The use of antioxidants in treatment of infertile men has been suggested, although the evidence base for this practice is unclear. A systematic review of randomized studies was conducted to evaluate the effects of oral antioxidants (vitamins C and E, zinc, selenium, folate, carnitine and carotenoids) on sperm quality and pregnancy rate in infertile men. MEDLINE, EMBASE, Cochrane Library and CINAHL were searched for relevant trials published from respective database inception dates to May 2009. Study selection, quality appraisal and data extraction were performed independently and in duplicate. Seventeen randomized trials, including a total of 1665 men, were identified, which differed in the populations studied and type, dosage and duration of antioxidants used. Only two-thirds of the studies (11/17) reported using allocation concealment and three studies (18%) used intention-to-treat analysis. Despite the methodological and clinical heterogeneity, 14 of the 17 (82%) trials showed an improvement in either sperm quality or pregnancy rate after antioxidant therapy. Ten trials examined pregnancy rate and six showed a significant improvement after antioxidant therapy. The use of oral antioxidants in infertile men could improve sperm quality and pregnancy rates. Adequately powered robust trials of individual and combinations of antioxidants are needed to guide clinical practice.

Non-hormonal therapy of post-menopausal vasomotor symptoms: a structured evidence-based review

Deepti Cheema; Arri Coomarasamy; Tarek El-Toukhy

BackgroundInterest in non-hormonal therapies for the treatment of menopausal symptoms has increased since the publication of adverse effects of estrogen replacement therapy.ObjectiveTo provide information on the efficacy of non-hormonal therapies for menopausal vasomotor symptoms based on evidence from published randomised controlled studies.MethodsThe Cochrane Database of Systematic Reviews (CDSR), MEDLINE, Alternative Therapies in Health and Medicine database (ATHMD) and Allied and Complementary Medicine database (AMED) were searched for randomised controlled trials in the English language reporting data on treatment of menopausal vasomotor symptoms. Trials including cancer breast patients were included.ResultsOur search identified 58 randomised controlled trials of which 11 involved the use of clonidine, six for SSRIs, four for gabapentin, seven for black cohosh, seven for red clover, 18 for phytoestrogens, two for ginseng, one for evening primrose, one for dong quai and one for vitamin E. Most trials had methodological deficiencies.ConclusionThere is evidence that clonidine, paroxetine, venlafaxine, gabapentin and black cohosh may be beneficial in the treatment of menopausal vasomotor symptoms in some women. Current evidence does not support the use of fluoxetine, red clover, phytoestrogens, Ginseng, evening primrose, dong quai and vitamin E. The side effects profile of these therapies should be considered.

A systematic review of studies evaluating the influence of outpatient (office) hysteroscopy on the outcome of the subsequent IVF cycle was conducted. MEDLINE, EMBASE, the Cochrane Library, National Research Register, ISI Conference Proceedings, ISRCTN Register and Meta-register were searched for randomized controlled trials (up to July 2007). All trials comparing the outcome of IVF treatment performed in patients who had outpatient hysteroscopy in the cycle preceding their IVF treatment with a control group in which hysteroscopy was not performed were included. Study selection, quality appraisal and data extraction were performed independently and in duplicate. Study authors were contacted for additional information. The main outcome measure was pregnancy rate. In total, 1691 participants were included in two randomized (n = 941) and three non-randomized controlled studies (n = 750). The quality of the studies was variable. Meta-analyses of the results of five studies showed evidence of benefit from outpatient hysteroscopy in improving the pregnancy rate in the subsequent IVF cycle (pooled relative risk = 1.75, 95% CI 1.51-2.03). The evidence from randomized trials was consistent with that from non-randomized controlled studies. Future robust randomized trials comparing outpatient hysteroscopy or mini-hysteroscopy with no intervention before IVF treatment would be a useful addition to further guide clinical practice.

Tarek El-Toukhy; Mohamed Hefni; Angharad E. Davies; S. Mahadevan

A prospective observational study was designed to evaluate the effect of the different techniques of hysterectomy on urinary and sexual function. One hundred and eighty-seven women aged 29 – 73 years and admitted for hysterectomy for various indications were recruited to the study. Women presenting primarily with major uterine prolapse and those requiring radical hysterectomy were excluded. Patients underwent one of four different techniques of hysterectomy: total abdominal, vaginal, laparoscopic or subtotal. All patients completed a standardised questionnaire addressing urinary and sexual symptoms and underwent urodynamic testing using the Lectromed 6000 System (Lectromed, Letchworth, Herts, UK) before and 6 months after surgery. Out of 187 women, 184 (98.4%) had completed data. Seventy-three patients (39%) had a total abdominal hysterectomy, 62 (34%) had vaginal, 38 (21%) had laparoscopic and 11 (6%) had subtotal hysterectomy. At 6 months after surgery, urinary symptoms occurred less frequently (P < 0.01) and urodynamic studies remained unchanged. Moreover, patients reported significantly lower rates of stress incontinence (P = 0.005), urgency (P = 0.03) and deep dyspareunia (P < 0.001) than before the operation, regardless of the hysterectomy technique used. The route of hysterectomy did not influence the outcome of surgery. We conclude that simple hysterectomy, whether performed abdominally, vaginally or laparoscopically, does not adversely affect urinary or sexual function at 6 months after surgery.
