The definition of unexplained infertility: A systematic review. BJOG 2023. [PMID: 37957032 DOI: 10.1111/1471-0528.17697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Revised: 09/21/2023] [Accepted: 10/15/2023] [Indexed: 11/15/2023]
Abstract
BACKGROUND There is no consensus on tests required to either diagnose unexplained infertility or use for research inclusion criteria. This leads to heterogeneity and bias affecting meta-analysis and best practice advice. OBJECTIVES This systematic review analyses the variability of inclusion criteria applied to couples with unexplained infertility. We propose standardised criteria for use both in future research studies and clinical diagnosis. SEARCH STRATEGY CINAHL and MEDLINE online databases were searched up to November 2022 for all published studies recruiting couples with unexplained infertility, available in full text in the English language. DATA COLLECTION AND ANALYSIS Data were collected in an Excel spreadsheet. Results were analysed per category and methodology or reference range. MAIN RESULTS Of 375 relevant studies, only 258 defined their inclusion criteria. The most commonly applied inclusion criteria were semen analysis, tubal patency and assessment of ovulation in 220 (85%), 232 (90%), 205 (79.5%) respectively. Only 87/220 (39.5%) studies reporting semen analysis used the World Health Organization (WHO) limits. Tubal patency was accepted if bilateral in 145/232 (62.5%) and if unilateral in 24/232 (10.3%). Ovulation was assessed using mid-luteal serum progesterone in 115/205 (56.1%) and by a history of regular cycles in 87/205 (42.4%). Other criteria, including uterine cavity assessment and hormone profile, were applied in less than 50% of included studies. CONCLUSIONS This review highlights the heterogeneity among studied populations with unexplained infertility. Development and application of internationally accepted criteria will improve the quality of research and future clinical care.

Effect of interval time between hysterosalpingography and intrauterine insemination on the pregnancy outcome of infertile patients. Front Endocrinol (Lausanne) 2023; 14:1175278. [PMID: 37964968 PMCID: PMC10641380 DOI: 10.3389/fendo.2023.1175278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Accepted: 08/30/2023] [Indexed: 11/16/2023] Open
Abstract
Background Hysterosalpingography (HSG) is the most commonly applied tubal patency test in clinical practice. Although some studies have found an increased pregnancy rate after HSG, no studies to date have specifically characterized the effect of interval time between HSG and IUI on pregnancy outcome. Objectives To investigate the effect of interval time between HSG and intrauterine insemination (IUI) on live birth rates of infertile patients. Methods Retrospective cohort study. The reproductive medical record system was used to identify patients who completed ≥1 IUI cycle between January 2017 and October 2021. According to the interval time between HSG and IUI, patients were divided into three groups: <6months interval group,6-12 months interval group and >12 months interval group. The generalized estimating equation with Poisson distribution was used to estimate the risk ratios (RRs) and 95% confidence intervals (CIs) of different groups. Results A total of 413 patients completed 701 IUI cycles during the study period, <6months interval group, 415 cycles; 6-12 months interval group, 138 cycles; >12 months interval group, 148 cycles. The live birth rate of <6 months group was higher than other two groups (17.35% vs. 12.32% vs. 8.11%, P=0.017); Similarly, the clinical pregnancy rate of <6 months group was also higher than other two groups (19.76% vs. 14.49% vs.11.49%, P=0.049). When adjusted separately for FSH, AMH, infertility type, duration of infertility, infertility diagnosis, total motile count (TMC) of sperm, medications, endometrium size and dominant follicle size, the live birth rate of >12 months group severally significantly decreased by 60% (adjusted RR = 0.40, 95% CI [0.19-1.40]). The cumulative clinical pregnancy and live birth rates of <6 months group were higher than other two groups (P<0.05), but the cumulative pregnancy rate among three groups were not statistically different (log rank test: P=0.06). Conclusion The interval time between hysterosalpingography and IUI is related to pregnancy outcome. The clinical pregnancy and live birth rates were the highest when the time interval was less than 6 months. Therefore, IUI should be recommend as soon as possible after HSG if the patient couple meets the IUI indication.

Safety of oil-based contrast medium for hysterosalpingography: a systematic review. Reprod Biomed Online 2021; 42:1119-1129. [PMID: 33931367 DOI: 10.1016/j.rbmo.2021.03.014] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 02/17/2021] [Accepted: 03/16/2021] [Indexed: 12/15/2022]
Abstract
Recent meta-analyses have shown that a hysterosalpingography (HSG) with oil-based contrast increases pregnancy rates in subfertile women. However, the frequency of complications during or after an HSG with oil-based contrast in subfertile women and/or their offspring is still unclear. This systematic review and meta-analysis, without restrictions on language, publication date or study design, was performed to fill this knowledge gap. The results show that the most frequently reported complication was intravasation of contrast, which occurred in 2.7% with the use of oil-based contrast (31 cohort studies and randomized controlled trials [RCT], 95% CI 1.7-3.8, absolute event rate 664/19,339), compared with 2.0% with the use of water-based contrast (8 cohort studies and RCT, 95% CI 1.2-3.0, absolute event rate 18/1006). In the cohort studies and RCT there were 18 women with an oil embolism (18/19,339 HSG), all without serious lasting consequences. Four cases with serious consequences of an oil embolism were described (retinal oil embolism [n = 1] and cerebral complaints [n = 3]); these reports did not describe the use of adequate fluoroscopy guidance during HSG. In conclusion, the most frequently reported complication after an HSG with oil-based contrast is intravasation occurring in 2.7%. In total four cases with serious consequences of oil embolisms in subfertile women were published.

Abstract
BACKGROUND Establishing the subgroup analysis of the fallopian tubes (tubes) is a commonly undertaken diagnostic investigation for women with subfertility. This is usually achieved by flushing contrast medium through the tubes and visualising patency on radiographs, ultrasonography or laparoscopy. Many women were noted to conceive in the first three to six months after tubal flushing, raising the possibility that tubal flushing could also be a treatment for infertility. There has been debate about which contrast medium should be used (water-soluble or oil-soluble media) as this may influence pregnancy rates. An important adverse event during tubal flushing is intravasation (backflow of contrast medium into the blood or lymphatic vessels),which could lead to embolism although it is asymptomatic in most cases. OBJECTIVES To evaluate the effectiveness and safety of tubal flushing with oil-soluble contrast media (OSCM) and water-soluble contrast media (WSCM) on subsequent fertility outcomes in women with subfertility. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility Group Specialised Register of controlled trials, MEDLINE, Embase, CENTRAL, PsycINFO, reference lists of identified articles and trial registries. The most recent search was conducted in April 2020. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing tubal flushing with OSCM, WSCM with each other or with no treatment, in women with subfertility. DATA COLLECTION AND ANALYSIS Two review authors independently selected the trials, assessed risk of bias and extracted data. We contacted study authors for additional information. The overall quality of the evidence was assessed using GRADE methods. MAIN RESULTS Fifteen trials involving 3864 women were included in this systematic review. Overall, the quality of evidence varied from very low to moderate: the main limitations were risk of bias, heterogeneity and imprecision. OSCM versus no treatment Four studies (506 women) were included in this comparison. Tubal flushing with OSCM may increase the odds of live birth (odds ratio (OR) 3.27, 95% confidence interval (CI) 1.57 to 6.85, 3 RCTs, 204 women, I2 = 0, low-quality evidence). This suggests that if the chance of live birth following no treatment is assumed to be 11%, the chance following tubal flushing with OSCM would be between 16% and 46%. Tubal flushing with OSCM may increase in the odds of clinical pregnancy (OR 3.54, 95% CI 2.08 to 6.02, 4 RCTs, 506 women, I2 = 18%, low-quality evidence). This suggests that if the chance of clinical pregnancy following no treatment is assumed to be 9%, the chance following tubal flushing with OSCM would be between 17% and 37%. No study measured intravasation or other adverse events such as infection, haemorrhage and congenital abnormalities. WSCM versus no treatment Only one study (334 women) was included in this comparison. We are uncertain whether tubal flushing with WSCM increase live birth compared to no treatment (OR 1.13, 95% CI 0.67 to 1.91, 1 RCT, 334 women, low-quality evidence). This suggests that if the chance of live birth following no treatment is assumed to be 21%, the chance following tubal flushing with WSCM would be between 15% and 33%. We are uncertain whether tubal flushing with WSCM increases clinical pregnancy compared to no treatment (OR 1.14, 95% CI 0.71 to 1.84, 1 RCT, 334 women, low-quality evidence). This suggests that if the chance of clinical pregnancy following no treatment is assumed to be 27%, the chance following tubal flushing with WSCM would be between 29% and 40%. One case with pelvic infection was reported in the WSCM group and no case with infection in the no treatment group in a one study (334 women). Meta-analysis was not performed due to the rare events. No study measured intravasation or other adverse events such as infection, haemorrhage and congenital abnormalities. OSCM versus WSCM Six studies (2598 women) were included in this comparison. Three studies reported live birth, including two with higher live birth in the OSCM group (OR 1.64, 95% CI 1.27 to 2.11, 1119 women; OR 3.45, 95% CI 1.97 to 6.03, 398 women); and one with insufficient evidence of a difference between groups (OR 0.92, 95% CI 0.60 to 1.40, 533 women). Given the substantial heterogeneity observed (I2 = 86%), meta-analysis was not performed. Tubal flushing with OSCM probably increased in the odds of intravasation (asymptomatic) compared to tubal flushing with WSCM (OR 5.00, 95% CI 2.25 to 11.12, 4 RCTs, 1912 women, I2 = 0, moderate-quality evidence). This suggests that if the chance of intravasation following tubal flushing with WSCM is assumed to be 1%, the chance following tubal flushing with OSCM would be between 2% and 9%. Tubal flushing with OSCM may increase the odds of clinical pregnancy (OR 1.42, 95% CI 1.10 to 1.85, 6 RCTs, 2598 women, I2 = 41%, low-quality evidence). This suggests that if the chance of clinical pregnancy following tubal flushing with WSCM is assumed to be 26%, the chance following tubal flushing with OSCM would be between 28% and 39%. We are uncertain whether tubal flushing with OSCM decreases the odds of infection (OR 0.22, 95% CI 0.04 to 1.22, 2 RCTs, 662 women, I2 = 0, very low-quality evidence) or haemorrhage (OR 0.65, 95% CI 0.40 to 1.06, 2 RCTs, 662 women, I2 = 0, very low-quality evidence). Three neonates with congenital abnormalities were reported in the OSCM group while no congenital abnormality was reported in the WSCM group in one study (1119 women). No meta-analysis was performed due to the rare events. AUTHORS' CONCLUSIONS The evidence suggests that compared to no treatment, tubal flushing with OSCM may increase the chance of live birth and clinical pregnancy, while it is uncertain whether tubal flushing with WSCM improves those outcomes. Compared to tubal flushing with WSCM, OSCM may improve clinical pregnancy while meta-analysis was impossible for live birth due to heterogeneity. Evidence also suggests that OSCM is associated with an increased risk of asymptomatic intravasation. Overall, adverse events, especially long-term adverse events, are poorly reported across studies.

Oil-based versus water-based contrast for hysterosalpingography in infertile women: a systematic review and meta-analysis of randomized controlled trials. Fertil Steril 2018; 110:153-160.e3. [PMID: 29908778 DOI: 10.1016/j.fertnstert.2018.03.021] [Citation(s) in RCA: 38] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2017] [Revised: 03/08/2018] [Accepted: 03/15/2018] [Indexed: 02/05/2023]
Abstract
OBJECTIVE To determine the effect of the using oil-soluble contrast material (OSCM) vs. water-soluble contrast material (WSCM) for hysterosalpingography on pregnancy rates in infertile women. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S) Infertile women. INTERVENTION(S) We included randomized controlled trials comparing pregnancy outcomes in women with infertility undergoing hysterosalpingography using OSCM and WSCM. Paired reviewers independently screened citations, assessed risk of bias of included studies, and extracted data. A random-effects model was used to report all outcomes. The Grading of Recommendations Assessment, Development, Evaluation(GRADE) system was used to quantify absolute effects and quality of evidence. MAIN OUTCOME MEASURE(S) The primary outcome was ongoing pregnancy per randomized women. RESULT(S) Six trials with a total of 2,562 patients were selected. Our meta-analysis showed OSCM was associated with significantly higher rates of ongoing pregnancy compared with WSCM (odds ratio [OR] 1.47, 95% confidence interval [CI] 1.12-1.93; I2 = 44%, moderate-quality evidence). Three trials reported live birth, but they were not pooled owing to extreme statistical heterogeneity (I2 = 86%). There was no difference in incidence of miscarriage (OR 0.83, 95% CI 0.56-1.24) or ectopic pregnancy (OR 0.65, 95% CI 0.18-2.36) between OSCM and WSCM groups. Three trials were rated as low risk of bias, whereas three were considered unclear. CONCLUSION(S) Women who previously underwent hysterosalpingography using oil contrast had higher rates of ongoing pregnancy compared with women who underwent this procedure using water contrast. There is not enough evidence to either support or oppose the difference between groups concerning miscarriage and ectopic pregnancy.

Abstract
Fallopian tube recanalization is a technique for treatment of proximal tubal obstruction caused by debris. The true frequency of infertile women for whom this treatment is suitable is not well known. In this study all hysterosalpingograms (HSGs) performed over a 3-year period (1986–88) were reviewed. The HSGs were performed as part of an infertility evaluation program in 494 women, with a mean duration of infertility of 2.4 years. Bilateral proximal tubal obstruction was found in 3% and unilateral proximal obstruction in 2% of the cases. In women examined in the first 2 years (1986–87) (n = 328), the birth frequency after HSG was 25%. When HSG was performed with optimal technique the number of patients who were suitable for Fallopian tube recanalization was low.

BACKGROUND Establishing the patency of the fallopian tubes is a commonly undertaken diagnostic investigation for women with subfertility. This is usually achieved by flushing contrast medium through the tubes and taking radiographs. However, it has been noted that many women conceive in the first three to six months after the tubal flushing, which has raised the possibility that tubal flushing could also be a treatment for infertility. There has been debate about which contrast medium should be used (water-soluble or oil-soluble media) as this may influence pregnancy rates. OBJECTIVES To evaluate the effect of flushing fallopian tubes with oil- or water-soluble contrast media on live birth and pregnancy rates in women with subfertility. SEARCH METHODS We searched the Cochrane Menstrual Disorders and Subfertility Group Specialised Register of trials, MEDLINE, EMBASE, Biological Abstracts, trial registers and reference lists of identified articles. The most recent search was conducted in June 2014. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing tubal flushing with oil-soluble or water-soluble contrast media, or with no treatment, in women with subfertility. DATA COLLECTION AND ANALYSIS Two authors independently selected the trials, assessed risk of bias and extracted data. We contacted study authors for additional information. The overall quality of the evidence was assessed using GRADE methods. MAIN RESULTS Thirteen trials involving 2914 women were included, of whom 2494 were included in the analysis. Oil-soluble contrast media (OSCM) versus no interventionThe OSCM group had a higher rate of live birth (odds ratio (OR) 3.09, 95% CI 1.39 to 6.91, 1 RCT, 158 women, low quality evidence) and ongoing pregnancy (OR 3.59, 95% CI 2.06 to 6.26, 3 RCTs, 382 women, I(2) = 0%, low quality evidence) than women who had no intervention. Our findings suggest that among subfertile women with a 17% chance of an ongoing pregnancy if they have no intervention, the rate will increase to between 29% and 55% if they have tubal flushing with OSCM. Water-soluble contrast media (WSCM) versus no interventionThere was no evidence of a difference between the groups in rates of live birth (OR 1.13, 95% CI 0.67 to 1.91, 1 RCT, 334 women, very low quality evidence) or ongoing pregnancy (OR 1.14, 95% CI 0.71 to 1.84, 1 RCT, 334 women, very low quality evidence). OSCM versus WSCMTwo RCTs reported live birth: one found a higher live birth rate in the oil-soluble group and the other found no evidence of a difference between the groups. These studies were not pooled due to very high heterogeneity (I(2) = 93%). There was no evidence of a difference between the groups in rates of ongoing pregnancy, however there was high heterogeneity (OR 1.44, 95% CI 0.84 to 2.47, 5 RCTs, 1454 women, I(2) = 76%, random-effects model, very low quality evidence). OSCM plus WSCM versus WSCM aloneThere was no evidence of a difference between the groups in rates of live birth (OR 1.06, 95% CI 0.64 to 1.77, 1 RCT, 393 women, very low quality evidence) or ongoing pregnancy (OR 1.23, 95% CI 0.87 to 1.72, 4 RCTs, 633 women, I(2) = 0%, low quality evidence).There was no evidence of a difference between any of the interventions in rates of adverse events, but such events were poorly reported in most studies. AUTHORS' CONCLUSIONS The evidence suggests that tubal flushing with oil-soluble contrast media may increase the chance of pregnancy and live birth compared to no intervention. Findings for other comparisons were inconclusive due to inconsistency and lack of statistical power. There was insufficient evidence on adverse events to reach firm conclusions. Further robust randomised controlled trials are needed.

Abstract
Tubal assessment is an integral part of female fertility evaluation. While diagnostic laparoscopy is gold standard, it is not suitable to be used as a screening test. Hysterosalpingogram (HSG) has been advocated as first-line investigation historically. With advances in diagnostics, more tests are available, such as hysterosalpingo contrast sonography (HyCoSy) and Chlamydia antibody titre (CAT) are available. The CAT test is much cheaper, less invasive and can be performed at any time during the cycle. The CAT test can also be used as a means of identifying which patients need further evaluation. HyCoSy has same diagnostic accuracy as HSG, without exposing women to radiation. We argue that HSG is out of date and has no place in a modern infertility evaluation. We also suggest a pathway (based on history, clinical and ultrasound evaluation) for investigations to screen for and diagnose tubal pathology.

Abstract
BACKGROUND A possible therapeutic effect of diagnostic tubal patency testing has been debated in the literature for half a century. Further debate surrounds whether oil-soluble or water-soluble contrast media might have the bigger fertility-enhancing effect. OBJECTIVES To evaluate the effect of flushing a woman's fallopian tubes with oil- or water-soluble contrast media on subsequent fertility outcomes in couples with infertility. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group's specialised register of trials (searched 31 January 2007), MEDLINE, EMBASE, Biological Abstract and reference lists of articles. SELECTION CRITERIA All randomised trials comparing tubal flushing with oil-soluble contrast media or tubal flushing with water-soluble media or with no treatment in women with subfertility. DATA COLLECTION AND ANALYSIS Four authors independently assessed trial quality and extracted data. We contacted study authors for additional information. We collected adverse effects information from the trials. MAIN RESULTS Twelve trials involving 2079 participants were included. Tubal flushing with oil-soluble media versus no intervention was associated with a significant increase in the odds of live birth (Peto OR 2.98, 95% CI 1.40 to 6.37) and of pregnancy (Peto OR 3.30, 95% CI 2.00 to 5.43). For the comparison of tubal flushing with oil-soluble media versus tubal flushing with water-soluble media, the increase in the odds of live birth for tubal flushing with oil-soluble versus water-soluble media (Peto OR 1.49, 95% CI 1.05 to 2.11) was based on two trials where statistical heterogeneity was present and the higher quality trial showed no significant difference; there was no evidence of a significant difference in the odds of pregnancy (Peto OR 1.21, 95% CI 0.95 to 1.54). The addition of oil-soluble media to flushing with water-soluble media showed no evidence of a significant difference in the odds of pregnancy (Peto OR 1.28, 95% CI 0.92 to 1.79) or live birth (Peto OR 1.06, 95% CI 0.64 to 1.77). There were no serious adverse event reported. AUTHORS' CONCLUSIONS There is evidence of effectiveness of tubal flushing with oil-soluble contrast media in increasing the odds of pregnancy and live birth versus no intervention. Future robust randomised trials, comparing oil-soluble versus water-soluble media, water-soluble media versus no intervention and tubal flushing versus established treatments for infertility would be a useful further guide to clinical practice.

Abstract
BACKGROUND Previous studies have assessed the validity of the observational study design by comparing results of studies using this design to results from randomized controlled trials. The present study examined design features of observational studies that could have influenced these comparisons. METHODS To find at least 4 observational studies that evaluated the same treatment, we reviewed meta-analyses comparing observational studies and randomized controlled trials for the assessment of medical treatments. Details critical for interpretation of these studies were abstracted and analyzed qualitatively. RESULTS Individual articles reviewed included 61 observational studies that assessed 10 treatment comparisons evaluated in two studies comparing randomized controlled trials and observational studies. The majority of studies did not report the following information: details of primary and ancillary treatments, outcome definitions, length of follow-up, inclusion/exclusion criteria, patient characteristics relevant to prognosis or treatment response, or assessment of possible confounding. When information was reported, variations in treatment specifics, outcome definition or confounding were identified as possible causes of differences between observational studies and randomized controlled trials, and of heterogeneity in observational studies. CONCLUSION Reporting of observational studies of medical treatments was often inadequate to compare study designs or allow other meaningful interpretation of results. All observational studies should report details of treatment, outcome assessment, patient characteristics, and confounding assessment.

Abstract
OBJECTIVE To determine whether treatment with lipiodol alters the leukocyte population in the uterus. DESIGN Randomized controlled animal study. SETTING University research laboratory. ANIMAL(S) Sixty female Swiss white mice at proestrous. INTERVENTION(S) Infusion of the female reproductive tract with lipiodol versus infusion with saline versus sham treatment. MAIN OUTCOME MEASURE(S) Counts of uterine macrophages, dendritic cells, and total leukocytes assessed by immunohistochemistry. RESULT(S) No statistically significant differences were found in the mean number of total leukocytes or macrophages between the three treatment groups. The mean number of CD205+ dendritic cells showed a statistically significant decrease following lipiodol treatment compared with the sham treatment and saline treatment. The mean number of CD1+ dendritic cells showed a statistically significant increase following lipiodol treatment compared with the sham treatment. CONCLUSION(S) Intrauterine lipiodol infusion is associated with a change in the uterine dendritic cell populations in mice. This change may alter the uterine immune response to the fetus, leading to improved fertility.

Abstract
BACKGROUND A possible therapeutic effect of diagnostic tubal patency testing has been debated in the literature for half a century. Further debate surrounds whether oil-soluble or water-soluble contrast media might have the bigger fertility-enhancing effect. Historically a variety of agents have been used to 'flush' the fallopian tubes, although tubal flushing does not currently form part of routine practice in the treatment of fertility delay. OBJECTIVES To evaluate the effect of flushing a woman's fallopian tubes with oil- or water-soluble contrast media on subsequent fertility outcomes in couples with infertility. SEARCH STRATEGY We searched the Cochrane Menstrual Disorders and Subfertility Group's specialised register of trials (searched 2 March 2004), MEDLINE (1966 to Mar 2004), EMBASE (1980 to Mar 2004), Biological Abstract (1980 to Mar 2004) and reference lists of articles. SELECTION CRITERIA All randomised trials where tubal flushing with oil-soluble contrast media or tubal flushing with water-soluble media was compared with one another or with no treatment were considered for inclusion in the review. DATA COLLECTION AND ANALYSIS Eleven randomised controlled trials were identified and included in this review. All trials were assessed for quality criteria. The studied primary outcome was live birth (and ongoing pregnancy), with secondary outcomes pregnancy, miscarriage, ectopic pregnancy, treatment complications including pain, intravasation of contrast medium, infection and haemorrhage, and image quality. MAIN RESULTS Tubal flushing with oil-soluble media versus no intervention (three trials including 381 participants) was associated with a significant increase in the odds of live birth (Peto OR 2.98, 95%CI 1.40 to 6.37) and of pregnancy (Peto OR 3.30, 95%CI 2.00 to 5.43). There were no data from RCTs to assess tubal flushing with water-soluble media versus no intervention. For the comparison of tubal flushing with oil-soluble media versus tubal flushing with water-soluble media (six trials including 1,483 participants), the increase in the odds of live birth for tubal flushing with oil-soluble versus water-soluble media (Peto OR 1.49, 95%CI 1.05 to 2.11) was based on two trials where statistical heterogeneity was present and the higher quality trial showed no significant difference; there was no evidence of a significant difference in the odds of pregnancy (Peto OR 1.24, 95%CI 0.97 to 1.57). The addition of oil-soluble media to flushing with water-soluble media (water-soluble plus oil-soluble media versus water-soluble media alone; three trials including 555 participants) showed no evidence of a significant difference in the odds of pregnancy (Peto OR 1.18, 95%CI 0.82 to 1.70) or live birth (Peto OR 1.06, 95%CI 0.64 to 1.77). Adverse event data were only available for the comparison OSCM versus WSCM: OSCM carried a significantly higher chance of intravasation (Peto OR 5.41, 95%CI 2.57 to 11.37) but a significantly lower chance of immediate pain (Peto OR 0.53, 95%CI 0.34 to 0.84), prolonged pain (Peto OR 0.26, 95%CI 0.15 to 0.45) and post-procedure bleeding (Peto OR 0.22, 95%CI 0.15 to 0.31), and no serious adverse events were reported. AUTHORS' CONCLUSIONS There is evidence of effectiveness of tubal flushing with oil-soluble contrast media in increasing the odds of pregnancy and live birth versus no intervention. The limited evidence of an increase in the odds of live birth from tubal flushing with oil-soluble contrast media versus water-soluble contrast media must be interpreted cautiously. Further robust randomised trials, comparing oil-soluble versus water-soluble media and comparing water-soluble media versus no intervention, would be a useful further guide to clinical practice. Further research is merited to ascertain the mechanism of the fertility enhancing effect of oil-soluble media, as to whether this is a 'tubal flushing' phenomenon, an effect on the intraperitoneal environment, or an implantation enhancing effect on the endometrium.

Abstract
There has been speculation for decades regarding the role of flushing women's fallopian tubes in improving the chance of pregnancy. More recent evidence has highlighted a possible specific role for lipiodol (ethiodized oil), an oil-soluble contrast medium, in the enhancement of fertility by these means. This systematic review was designed to assess the effectiveness of tubal flushing with various contrast media in improving the chance of pregnancy. The review was performed using Cochrane guidelines, including only data from randomized controlled trials. Results confirm the effectiveness of flushing with lipiodol in improving the chance of pregnancy and live birth. Although there was limited evidence to suggest a possible benefit of oil- over water-soluble contrast media, the answer to this question remains unclear. The specific groups who appear to benefit most from lipiodol flushing are couples with unexplained infertility, but particularly couples where the woman has endometriosis in the context of normal patent fallopian tubes. As a simple, low-cost, minimally invasive intervention that carries a low risk of complications and no increased risk of multiple pregnancy, lipiodol flushing may prove an appealing alternative to established fertility treatments for many couples.

Abstract
AIM To investigate the prognostic significance of hysterosalpingography carried out before one-sided gamete intrafallopian transfer for unexplained infertility. METHODS Fifty-nine first gamete intrafallopian transfer cycles in 59 couples with unexplained infertility were evaluated in two groups: 30 women with a hysterosalpingogram carried out 1-6 months prior to gamete intrafallopian transfer procedure combined with diagnostic laparoscopy, and 29 women with a hysterosalpingogram carried out during any other interval up to 2 years. The outcome measures were biochemical pregnancy, clinical pregnancy, miscarriage, preterm delivery, and term delivery. Groups were compared using Student's t-test and chi-squared tests. Logistic regression was used to predict the effects of hysterosalpingography on subsequent fertility outcomes. RESULTS Univariate analysis yielded no significant differences across groups regarding the baseline characteristics and outcome measures. When confounding factors were controlled, carrying out hysterosalpingography at some time before 6 months of gamete intrafallopian transfer was associated with 5.2- and 3.4-fold increased clinical pregnancy and term delivery rates, respectively. CONCLUSIONS An additional hysterosalpingography at most 6 months prior to gamete intrafallopian transfer procedure might improve fertility prospects. This effect could be attributed to proper selection of the fallopian tube for cannulation during transfer or some therapeutic effect of hysterosalpingography.

Abstract
PURPOSE To determine the pregnancy outcomes in patients undergoing fallopian tube recanalization (FTR) with use of oil-based versus water-soluble contrast agents. MATERIALS AND METHODS Ninety-three patients with unilateral or bilateral proximal tubal occlusion confirmed by hysterosalpingography or laparoscopy underwent FTR with use of water-soluble contrast material alone (n = 50) or also had an oil-based agent injected into each tube after recanalization (n = 43). Pregnancy rates and outcomes of the two groups were studied retrospectively. RESULTS With respect to differences between groups, only the body mass index proved to be a significant predictor (oil, 28.4; water, 24.7; P =.008). Mean age, duration of infertility, type of infertility, and initial diagnosis were comparable. There was a weak trend toward a higher pregnancy rate in the oil-based contrast material group, but it was not significant (P =.64). The average time to pregnancy was 4.4 months with use of oil-based contrast material, compared to 7.7 months with use of only water-soluble contrast material (P =.03). CONCLUSION The use of an oil-based agent had little effect on the rate of conception, but time to conception was reduced by more than 3 months.

Abstract
BACKGROUND There has been debate in the literature for more than 40 years as to whether flushing of the Fallopian tubes enhances fertility and whether this presumed therapeutic effect is greater with oil-soluble media than with water-soluble media. A meta-analysis of the therapeutic role of oil-soluble contrast media at hysterosalpingography was published in March 1994 (Watson 1994). This Cochrane Review is an expansion and update of that overview. OBJECTIVES To evaluate the effect of flushing the Fallopian tubes with oil- or water-soluble contrast media on subsequent pregnancy rates in infertility patients. SEARCH STRATEGY 1. For randomised controlled trials (RCTs): we searched the Cochrane Subfertility Review Group specialised register of controlled trials. 2. For non-randomised controlled studies: Medline and manual search of eight relevant journals. SELECTION CRITERIA Six RCTs and six non-randomised controlled studies. In two studies tubal flushing was compared with no treatment-controls. Eleven studies, comprising a total of 2635 subjects, compared oil- with water-soluble media. DATA COLLECTION AND ANALYSIS Independently by first 2 authors for: 1. Methodological trial characteristics 2. Characteristics of participants 3. OUTCOMES the main studied outcome was pregnancy rate per patient MAIN RESULTS In comparison with no treatment, a significant benefit on pregnancy rates was seen by flushing the tubes with oil-soluble media (OR 1.80, 95% CI 1.29-2.50) but not with water-soluble media (OR 0.87, 95% CI 0.50-1.52). In the direct comparison of oil- and water-soluble media the former lead to significantly higher pregnancy rates (OR 1.92, 95% CI 1.60-2.29). The treatment effect appeared similar in RCTs and non-RCTs. Subgroup analysis suggested the therapeutic benefit was greatest for patients suffering from unexplained infertility and least for those with tubal factor infertility. REVIEWER'S CONCLUSIONS Flushing of the tubes with oil-soluble media increases subsequent pregnancy rates in infertility patients. The hypothesis that tubal "plugs" are a cause of proximal tubal occlusion and that oil-soluble media may flush them out, is supported by new techniques such as falloposcopy. Clinicians should consider flushing the tubes with OSCM before contemplating more invasive therapies.

Abstract
PURPOSE To evaluate the influence of the contrast material used in hysterosalpingography (HSG) on subsequent reproductive success, independent of other therapeutic interventions. MATERIALS AND METHODS In a prospective, multisite, randomized trial, 666 women who had been infertile for more than 1 year and were scheduled to undergo HSG as part of their evaluation were assigned to one of three groups: those receiving water-soluble contrast material (WSCM) (n = 260), those receiving oil-soluble contrast material (OSCM) (n = 273), and those receiving both OSCM and WSCM (n = 133). Possible causes of infertility and therapeutic interventions were abstracted from the medical records. Data on conception within 1 year and the outcome of conception were ascertained from multiple sources. RESULTS Of 666 women, 204 (30.6%) had at least one pregnancy, and 136 (20.4%) had live births. The rates of live births were 20.4% (54 of 260) after HSG with WSCM, 19.4% (53 of 273) after HSG with OSCM, and 21.8% (29 of 133) after HSG with both WSCM and OSCM. Differences in reproductive outcome among contrast material groups were not statistically significant ((chi2)8 = 6.08, P = .64). Whatever the cause of infertility, the use of different contrast materials led to no significant differences in the rates of live births. CONCLUSION There is no evidence to suggest that the choice of contrast material affects the rate of term pregnancy.

Abstract
The influence of an oil contrast medium on fertilization in rabbit oviducts was investigated. The oil contrast medium (Lipiodol-UF) was injected into the catheterized oviducts of anaesthetized animals, and they were mated 1, 3, 5 or 7 days later. When mating took place 1 day after injection, none of the ova that were subsequently recovered were fertilized; the fertilization rates when mating occurred 3, 5 or 7 days after injection of the medium were 78.9, 90 and 100%. Fertilization within the oviduct was, thus, impaired by the injection of oil contrast medium, but appeared to be fully recovered 7 days later.

Abstract
OBJECTIVE To evaluate the therapeutic effect of oil-soluble contrast media compared with water-soluble contrast media after hysterosalpingography (HSG) in infertile couples. DESIGN Meta-analysis of four randomized clinical trials (RCTs) and six nonrandomized controlled studies evaluating pregnancy rates after the use of oil- or water-soluble contrast media during HSG. SETTING Institute of Epidemiology and Health Services Research, Leeds, United Kingdom. PATIENTS Four identified RCTs studied 800 patients and six nonrandomized studies comprised an additional 1,806 patients, all experiencing primary or secondary infertility. INTERVENTION Hysterosalpingography as part of infertility investigation. MAIN OUTCOME MEASURE Pregnancy rates after HSG. RESULTS Pregnancy rates were significantly higher in the oil-soluble contrast media group compared with the water-soluble contrast media group in the RCTs. Inclusion of the six nonrandomized studies did not alter this conclusion. This apparent benefit was greatest for patients with unexplained infertility. CONCLUSIONS Oil-soluble contrast media have a therapeutic effect compared with water-soluble media and this effect is greatest for patients who have been diagnosed as having unexplained infertility. New techniques for the evaluation of tubal patency support the hypothesis that tubal "plugs" may be involved in proximal tubal blockage.

Abstract
We analyzed the importance of 3 factors derived from the HSG (nature of the mucosal pattern, diameter of the hydrosalpinx, expandability of the ampulla) and of four factors from the findings at laparoscopy (extent of adhesions, nature of adhesions, thickness of tubal wall and diameter of the hydrosalpinx) for predicting the pregnancy outcome in 98 patients with bilateral hydrosalpinx. Each factor was categorized into 3 scores and each patient was scored for both the right and the left tube, resulting in 6 score-combinations. An association between the pregnancy prospects based on the score-combinations and the actual pregnancy outcome seemed to be present for all factors evaluated, except for the extent of adhesions and the diameter of the hydrosalpinx (laparoscopy). The results further indicate that a favourable score on the nature of mucosal pattern in one or both tubes concurs with good pregnancy prospects. In contrast, the presence of an unfavourable score for most of the other factors in at least one tube is associated with a poor fertility prognosis, regardless of the condition of the other tube.

Abstract
In this prospective randomized clinical study the pregnancy rate and the quality of the images obtained by hysterosalpingography (HSG) in 175 women with fertility problems have been compared using an oil-soluble contrast medium and an aqueous contrast medium. After the HSG there was a follow-up period of 6 months. No statistically significant difference in pregnancy rate was found. With both contrast media good images were obtained. The oil-soluble contrast medium gave a more sharply outlined uterine cavity, the aqueous contrast medium showed more tubal details. Furthermore, the control picture with the aqueous contrast medium can be prepared after ten minutes. We conclude that the use of an aqueous contrast medium for routine HSG is preferable.

Abstract
Previous studies have suggested increased fertility rates following hysterosalpingography (HSG) using oil as compared with aqueous contrast medium. To compare the possible fertility-enhancing effects of two agents used for HSG, this prospective randomized study evaluated the subsequent fertility rates in 121 patients who underwent HSG, in which either oil or aqueous contrast medium was used. After random assignment to either agent, patients were observed for four menstrual cycles after HSG without resorting to any therapy other than clomiphene citrate where indicated. The pregnancy rates for the four cycles after HSG were compared with chi-square analysis in the total study and in the diagnostic subgroups. The subgroup with infertility of unknown cause had a significantly higher pregnancy rate after HSG with oil than after HSG with aqueous contrast medium. No significant difference was seen for any other subgroup or for the overall cohort.

Abstract
Hysterosalpinography (HSG) was performed in 220 women for evaluation of infertility. Laparoscopy or laparotomy for final assessment of tubal patency were carried out in 110. HSG revealed a normal tubal patency in 66.8 per cent, whereas abnormal patency was found in 24.1 per cent. At operation, 85.7 per cent of the HSG diagnoses were confirmed. A clear correlation existed between previous lesions in the genital tract and pathologic findings at HSG and operation. The pregnancy rate following HSG was 15.4 per cent. It is concluded that HSG is of great value in the initial evaluation of infertility. The findings facilitate the decision regarding the final operative procedure: laparoscopy or laparotomy.

Abstract
Sixty-five patients with minimal endometriosis were studied for the purpose of prospectively comparing conservative medical management in the form of danazol with no therapy in the treatment of this disease. After completion of the basic infertility evaluation and correction of additional factors affecting fertility, a diagnostic laparoscopy, dilatation and curettage (D and C), and tubal lavage were performed. A randomly selected cord determined whether the patient received no treatment for 6 months or danazol for 6 months followed by no treatment for 6 months. The dosage of danazol was 800 mg daily for the first 2 months, 600 mg daily for the next 2 months, and 400 mg daily for the final 2 months. The mean age of both the danazol-treated group and the group that received no danazol was 31 years. Conception occurred in 30% of the danazol-treated patients and 50% of the untreated patients. These results suggest that infertile patients with minimal endometriosis should be given an opportunity to conceive after laparoscopy, D and C, and tubal lavage. This would seem particularly true in older patients where a 6-month delay in permitting attempts at conception represents a significant interval of time.

Abstract
Because of potential mutagenic effects of radiation on the soon-to-be fertilized ovum, we questioned whether we should advise against conception during the cycle in which a hysterosalpingogram is performed. Our results do not suggest any increase in the incidence of spontaneous abortion or congenital anomalies in these patients. Therefore, we see no need to advise against conception during the cycle in which a hysterosalpingogram is performed.

Abstract
Two hundred and fifty of 323 laparoscopically sterilized patients had hysterosalpingographic (HSG) follow-up. A Foley catheter was used in hysterosalpingography. Of these patients, 3.6 per cent demonstrated fistula; 1.2 per cent were found to have round ligament burns, and 0.618 per cent became pregnant. Mechanism of fistula formation, prevention, and management is discussed. The incidence of intrauterine pregnancy and ectopic pregnancy after laparoscopic sterilization is discussed, and the literature is reviewed. Based on these data, it is concluded that HSG follow-up is helpful in teaching institutions and where the laparoscopic sterilization is carried out by inexperienced operators. Routine HSG follow-up is not recommended.

Abstract
A comparison of hysterosalpingography and laparoscopy was carried out on 79 infertile women. Out of these, 60 had abnormal and 19 had normal hysterosalpingograms. Of the 19 patients with normal X-rays, nine (47%) had abnormal findings during laparoscopy. In 62% of patients with abnormal hysterosalpingograms, laparoscopic findings confirmed the radiological diagnosis, however in 38% the findings differed. Though hysterosalpingography is an important part of infertility evaluation, a final and definite diagnosis requires endoscopic evaluation of the pelvis.
