Abstract
The mesenchymal to epithelial transition (MET) is thought to be involved in the maintenance, repair, and carcinogenesis of the fallopian tube (oviduct) and uterine epithelium. However, conclusive evidence for the conversion of mesenchymal cells to epithelial cells in these organs is lacking. Using embryonal cell lineage tracing with reporters driven by mesenchymal cell marker genes of the female reproductive tract (AMHR2, CSPG4, and PDGFRβ), we show that these reporters are also expressed by some oviductal and uterine epithelial cells at birth. These mesenchymal reporter-positive epithelial cells are maintained in adult mice across multiple pregnancies, respond to ovarian hormones, and form organoids. However, no labeled epithelial cells are present in any oviductal or uterine epithelia when mesenchymal cell labeling was induced in adult mice. Organoids developed from mice labeled in adulthood were also negative for mesenchymal reporters. Collectively, our work found no definitive evidence of MET in the adult fallopian tube and uterine epithelium. Mesenchymal to epithelial transition (MET) is postulated to be involved in the maintenance and regeneration of the epithelium of female reproductive organs. Here, Ghosh et al. report no definitive evidence of MET in the adult epithelium of oviduct and uterus using in vivo cell lineage tracing and organoids.

Abstract
Fallopian tube obstruction (FTO) is a common cause of female infertility. In the setting of proximal FTO, fallopian tube recanalization (FTR) is a minimally invasive, ambulatory procedure with a technical success rate of up to 100%, with minimal postprocedural adverse events. One-year pregnancy rate following FTR is approximately 41%, with successful delivery of full-term infants in 84% of pregnancies. This minimally invasive, outpatient, image-guided procedure is an alternative to vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) and should be top-of-mind in the setting of infertility due to proximal FTO.

Abstract
PURPOSE To compare hysterosalpingo-contrast-sonography (HyCoSy) and magnetic resonance-hysterosalpingography (MR-HSG) in the diagnosis of fallopian tubal patency. MATERIALS AND METHODS The databases of PubMed, Embase, and the Cochrane Library were searched for records up to November 30, 2019. Studies involved in the diagnostic detection of HyCoSy or MR-HSG for fallopian tubal patency using conventional HSG or laparoscopy as the reference test were included. Data was analyzed by meta-analysis. We compared sensitivity, specificity, positive and negative likelihood ratios (PLR and NLR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (sROC) plots of both HyCoSy and MR-HSG. Quality was assessed using the QUADAS-2 tool. RESULTS The analysis included 24 articles involving 1340 patients. HyCoSy was studied in 17 studies, and MR-HSG was studied in seven studies. For HyCoSy in diagnosis of fallopian tubal patency, pooled sensitivity was 89 % (95 % confidence interval [CI], 87 %-91 %), and specificity was 93 % (95 % CI, 91 %-94 %). For MR-HSG in diagnosis of fallopian tubal patency, pooled sensitivity was 100 % (95 % CI, 98 %-100 %), and specificity was 82 % (95 % CI, 74 %-89 %). The sROC showed similar diagnostic accuracy for MR-HSG and HyCoSy. 3D/4D HyCoSy with ultrasound microbubbles had equal sensitivity (95 % vs. 100 %, P = 0.186) and significantly higher specificity (94 % vs. 82 %, P = 0.005) compared with MR-HSG. CONCLUSIONS HyCoSy and MR-HSG showed similar overall diagnostic performance for diagnosing fallopian tubal patency. 3D/4D HyCoSy with ultrasound microbubbles could significantly improve the diagnostic specificity of HyCoSy.

Abstract
OBJECTIVES To compare, in women with infertility, the effectiveness and safety of tubal flushing using oil-based contrast medium, water-based contrast medium or their combination, and no tubal flushing, and to evaluate the effectiveness of tubal flushing on fertility outcome over time. METHODS We performed a systematic review and network meta-analysis, searching the electronic databases MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials, and trial registries, up to 25 September 2018. We included randomized controlled trials (RCTs) comparing the following interventions with each other or with no intervention in women with infertility: tubal flushing using water-based contrast medium, tubal flushing using oil-based contrast medium or additional tubal flushing with oil-based medium following diagnostic tubal flushing with water-based medium. The outcomes included clinical pregnancy, live birth, ongoing pregnancy, miscarriage, ectopic pregnancy and adverse events. RESULTS Of the 283 studies identified through the search, 14 RCTs reporting on 3852 women with infertility were included. Network meta-analysis showed that tubal flushing using oil-based contrast medium was associated with higher odds of clinical pregnancy within 6 months after randomization and more subsequent live births compared with tubal flushing using water-based medium (odds ratio (OR), 1.67 (95% CI, 1.38-2.03), moderate certainty of evidence; and OR, 2.18 (95% CI, 1.30-3.65), low certainty of evidence, respectively) and compared with no intervention (OR, 2.28 (95% CI, 1.50-3.47), moderate certainty of evidence; and OR, 2.85 (95% CI, 1.41-5.74), low certainty of evidence, respectively). These results agreed with those of the pairwise meta-analysis. For clinical pregnancy within 6 months, there was insufficient evidence of a difference between tubal flushing with water-based contrast medium and no intervention (OR, 1.36 (95% CI, 0.91-2.04), low certainty of evidence). For fertility outcomes after 6 months, there was insufficient evidence of a difference in any comparison (low to very low certainty of evidence). Compared with tubal flushing using water-based contrast medium, the use of oil-based contrast medium was associated with higher odds of asymptomatic intravasation (OR, 5.06 (95% CI, 2.29-11.18), moderate certainty of evidence). CONCLUSIONS In women with infertility undergoing fertility workup, tubal flushing using oil-based contrast medium probably increases clinical pregnancy rates within 6 months after randomization and may increase subsequent live-birth rates, compared with tubal flushing using water-based contrast medium and compared with no intervention. Evidence on fertility outcomes beyond 6 months is inadequate to draw firm conclusions. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Tubal patency testing is an essential part of female subfertility evaluation. Traditionally, hysterosalpingography (HSG) was the first step to evaluate tubal patency. However, during the past decade Hysterosalpingo-Contrast Sonography (HyCoSy) was introduced in order to avoid radiation exposure and Hysterosalpingo-Foam Sonography (HyFoSy) has been developed as a safe and less painful alternative. OBJECTIVES AND RATIONALE The aim of this narrative review is to provide an overview of the currently available HyFoSy literature and related clinical aspects. SEARCH METHODS A literature search was conducted using PubMed and Embase from the introduction of HyFoSy to March 2019. Unfortunately, a meta-analysis was not possible due to a too small number of studies, being mutually incomparable for the various subjects of clinical aspects, even for the reliability as a test for tubal patency. OUTCOMES Nine small studies concluded that the accuracy and effectiveness as a test for tubal patency of 2D- and 3D-HyFoSy are comparable or even better than HSG or HyCoSy. With or without using Doppler techniques, 3D-HyFoSy does not seem to offer benefits above real-time 2D-HyFoSy. Five studies reported on pain and discomfort during HyFoSy, concluding that HyFoSy is a well-tolerated, less painful procedure compared to HSG, without a need for the use of analgesics. There are suggestions about an increased pregnancy rate in the first three cycles after the procedure but in no studies pregnancy outcome after HyFoSy was compared with other or no intervention. WIDER IMPLICATIONS HyFoSy is a promising and safe alternative for HSG with regard to accuracy and effectiveness. HyFoSy lacks radiation and iodine exposure and is a well-tolerated and less painful procedure than HSG, without the need for analgesics. However more research is needed to make clear statements regarding a therapeutic effect of HyFoSy.

Abstract
BACKGROUND Pelvic endometriosis (EM) and adenomyosis (AM) have different effects on the fallopian tube. This study aimed to assess the transport capability of the fallopian tube in women with pelvic EM or AM. METHODS Twenty women with uterine leiomyoma (control group), 20 with adenomyosis without pelvic EM (AM group) and 35 with pelvic EM without AM (EM group) were included. EM cases were further divided into the tubal EM and non-tubal EM subgroups. Ciliary beat frequency (CBF), percentage of ciliated cells, and smooth muscle contraction were measured. RESULTS CBFs of the ampulla in EM cases were significantly lower than those of control and AM cases; CBFs of the ampulla and isthmus in tubal EM cases were significantly lower than those of the control group and non-tubal EM subgroup. In both the ampulla and isthmus segment, percentages of ciliated cells in EM patients were significantly lower than those of AM and control patients; the tubal EM subgroup showed significantly lower values than the control group and non-tubal EM subgroup. Amplitude-to-weight ratios of longitudinal muscular contractility in EM cases were significantly lower than control values; tubal EM cases showed significantly lower values than controls and the non-tubal EM subgroup. Contraction frequencies in EM cases were significantly lower than those of control and AM cases, in both longitudinal and circular muscles; tubal EM cases showed significantly lower values than controls and the non-tubal EM subgroup. CONCLUSION EM with tubal EM damaged transport function of the fallopian tube, to varying degrees, whereas tubal function in EM without tubal EM and in AM is not altered.

Abstract
Telocytes are emerging cell population localized in the stroma of numerous organs, characterized by a distinctive morphology - small cell body with very long, slender prolongations, termed telopodes. Those cells can be found in the whole female reproductive system: in the vagina, uterus, oviducts and ovaries, mammary glands and also in the placenta. In our review, we aim at complete and transparent revision of the current knowledge of telocytes' localization and function, enriched by the analysis of the possible future direction of development of their clinical applications. The function of telocytes in the reproductive system has not been fully elucidated yet; however, many researchers point at their role in the regulation of local microenvironment, myogenic contractile mechanism, bioelectrical signaling, immunomodulation and regulation of blood flow. Additionally, previous research suggests that telocytes might act as sex hormone level sensors and are connected with pregnancy maintenance. As the morphology and number of those cells change under pathological conditions, such as pre-eclampsia, endometriosis and ovarian failure, there is a chance that they may contribute to therapy of abovementioned conditions. The impact of telocytes on stem cells and angiogenesis has been proven in many organs, and may be useful in regenerative medicine of the female reproductive system. A recently found connection between the proliferation rate of breast cancer cells and stromal cells like telocytes might be a step forward to the management of mammary gland neoplasms.

Abstract
OBJECTIVES The purpose of this study was to evaluate the performance of 4-dimensional (4D) hysterosalpingo-contrast sonography (HyCoSy) for assessing fallopian tube fimbria patency in infertile women. METHODS Seventy-seven infertile female patients with obstruction at the tubal fimbria or partial obstruction with pelvic adhesions were included. All of the patients underwent 4D HyCoSy enhanced by dynamic observation after a flush of normal saline and were followed with laparoscopic chromopertubation using methylene blue within 6 months. RESULTS The overall accordance between 4D HyCoSy and laparoscopic chromopertubation was 92.9%. The sensitivity and specificity of 4D HyCoSy with laparoscopic chromopertubation as a reference standard were 93.8% and 92.2%, respectively. CONCLUSIONS Four-dimensional HyCoSy can be the preferred method for assessment of tubal fimbria patency and pelvic adhesions surrounding the ovaries, with its advantages of accuracy, noninvasiveness, and a good safety profile.

Abstract
The local immune system in the oviduct has a unique ability to deal with pathogens, allogeneic spermatozoa, and the semi-allogeneic embryo. To achieve this, it seems likely that the oviduct possesses an efficient and strictly controlled immune system that maintains optimal conditions for fertilization and early embryo development. The presence of a proper sperm and/or embryo-oviduct interaction begs the question of whether the local immune system in the oviduct exerts beneficial or deleterious effects on sperm and early embryo; support or attack?. A series of studies has revealed that bovine oviduct epithelial cells (BOECs) are influenced by preovulatory levels of Estradiol-17β, progesterone, and LH to maintain an immunologic homeostasis in bovine oviduct, via inhibition of proinflammatory responses that are detrimental to allogenic sperm. Under pathologic conditions, the mucosal immune system initiates the inflammatory response to the infection; the bacterial lipopolysaccharide (LPS) at low concentrations induces a proinflammatory response with increased expression of TLR-4, PTGS2, IL-1β, NFκB1, and TNFα, resulting in tissue damage. At higher concentrations, however, LPS induces a set of anti-inflammatory genes (TLR-2, IL-4, IL-10, and PTGES) that may initiate a tissue repair. This response of BOECs is accompanied by the secretion of acute phase protein, suggesting that BOECs react to LPS with a typical acute proinflammatory response. Under physiological conditions, polymorphonuclear neutrophils (PMN) are existent in the oviductal fluid during preovulatory period in the bovine. Interestingly, the bovine oviduct downregulates sperm phagocytosis by PMN via prostaglandin E2 (PGE2) action. In addition, the angiotensin-endothelin-PGE2 system controlling oviduct contraction may fine-tune the PMN phagocytic behavior to sperm in the oviduct. Importantly, a physiological range of PGE2 supplies anti-inflammatory balance in BOEC. Our recent results show that the sperm binding to BOECs further shift the local immunity toward anti-inflammatory conditions with upregulation of IL-10, TGFβ, and PGE2. In addition, this local environment leads PMN to express anti-inflammatory cytokines. In conclusion, the oviduct displays mucosal immunity that maintains an anti-inflammatory environment under physiological conditions that supports the sperm. Under pathologic condition, however, the oviduct supplies the innate immunity that may attack the sperm. Moreover, the oviduct-sperm interaction further suppresses the innate immune cells and strengthens the anti-inflammatory balance in the oviduct. Therefore, the oviduct immunity ensures sperm viability before fertilization.

Abstract
Tubal sterilization is one of the most commonly employed permanent method of contraception, although it is considered very safe, rarely a cyst may develop in the fallopian tube after sterilization which may undergo torsion resulting in patient presenting with acute abdomen. We are presenting a case of a middle aged women presenting to emergency room with severe lower abdominal pain, she had past history of tubal ligation done 12 years back. Pelvic ultrasound showed right sided ovarian cyst, emergency laparotomy was performed for suspected torsion of ovarian cyst, which revealed normal ovary, however a right sided fallopian tube cyst was present which had undergone torsion, right sided salpingectomy was performed and the patient was sent home in stable condition on the fourth postoperative day.

Abstract
Discovery of telocytes has become an important and key challenge in past few years. These cells are interstitial cells extending very long cytoplasmic processes named telopodes, by which they create functional networks in the interstitium of different organs. Telocytes are considered to be connective tissue elements that create contacts among each other, but they also function as intercellular structures, functionally connected with cells of the immune system, neurons and smooth muscle cells. Telocytes can be found also in the different parts of female reproductive system with functions and purpose, which is summarized in our overview. Telocytes regulate for example peristaltic movements in fallopian tubes. The decrease of their number (due to inflammatory disease or endometriosis) causes impairment in transport through fallopian tubes which may result in sterility or tubal gravidity. In uterus they regulate contraction of myometrial smooth muscle (blood expulsion in menstrual phase, childbirth) as well as they contribute in immunological care during embryo implantation. Telocytes probably control also the involution of uterus after delivery. Their function in vagina has not been yet clearly defined; they probably take part in slow muscle contraction movement during sexual intercourse. In mammary glands some scientists suppose their function in control of cell proliferation and apoptosis, that is why, they may play a role in carcinogenesis. In placenta they probably monitor and regulate flow of blood in vessels of chorionic villi and they may be responsible also for etiopathogenesis of pre-eclampsy. All these mentioned functions of telocytes are only in the level of hypothesis and have been published recently. New research and studies will try to answer the questions whether telocytes play a key role in these processes. Our review we completed with some original microphotographs of telocytes in different organs of female reproductive system.

Abstract
Embryo implantation is a major prerequisite for the successful establishment of pregnancy. Ectopic implantation outside the intrauterine cavity and the development of ectopic pregnancy (EP) is a major cause of maternal morbidity and occasionally mortality during the first trimester. EP may be induced by failure of tubal transport and/or increased tubal receptivity. Activins, their type II receptors and follistatin have been localised in the human endometrial and tubal epithelium and they are major regulators of endometrial and tubal physiology during the menstrual cycle. Pathological expression of activins and their binding protein, follistatin, was observed in tissue and serum samples collected from EP. Several studies with different designs investigated the diagnostic value of a single measurement of serum activin-A in the differentiation between normal intrauterine and failing early pregnancy and the results are controversial. Nevertheless, the diagnostic value of activins in EP, including the other activin isoforms (activin-B and -AB) and follistatin, merits further research. This review appraises the data to date researching the role of activins in the establishment of normal pregnancy and, pathogenesis and diagnosis of tubal EP.

Abstract
OBJECTIVE To investigate histopathological and immunohistochemical changes in the Fallopian tube structure following ovarian torsion. STUDY DESIGN Thirty fertile, female, adult Wistar albino rats, weighing 200-220 g, were randomly divided into 3 equal groups (n = 10): sham, torsion, and detorsion. In the torsion and detorsion groups, bilateral adnexal torsion (3-hour ischemia) was carried out. Bilateral adnexal detorsion (3-hour reperfusion) was performed in the detorsion group. Fallopian tube sections were stained hematoxylin and eosin, periodic acid-Schiff, Mallory-Azan and immunohistochemically-stained desmin, α smooth actin, and CD68 antibodies. RESULTS In the sections of the ischemic group, degeneration of epithelium, loss of cilia, dilation of blood vessels, and hemorrhages were observed. Image analysis of the studied Fallopian section revealed a significant decrease in density of desmin in the torsion group. Moreover, strong positive cytoplasmic CD68 expression was observed in the torsion group. CONCLUSION The use of effective antiinflammatory treatments may contribute to the conservative surgery in preservation of ovarian reserve and tubal structure.

Abstract
Oviduct tubal motility is thought to be controlled by hormones and nerves and has been associated with endometriosis. However, it is still not known whether the fallopian tubes in women with endometriosis demonstrate an abnormal distribution of nerve fibers. The objective of this study was to determine the distribution of nerve fibers in the oviduct isthmus in women with and without endometriosis. Histological sections of the oviduct isthmus tissues were obtained from women undergoing hysterectomy for endometriosis (n=24) and other benign gynecologic diseases (n=24). The tissues were immunohistochemically stained for protein gene product (PGP) 9.5, substance P (SP), neuropeptide Y (NPY), and vasoactive intestinal peptide (VIP) to reveal all nerve fibers, sensory nerve fibers and sympathetic and parasympathetic nerve fibers. Nerve fibers stained with PGP9.5, VIP and NPY in the oviduct isthmus were all significantly decreased in women with endometriosis as compared with women without endometriosis (P<0.05). In women with endometriosis, reduced nerve fibers stained with PGP9.5 and SP in the serosal layer, NPY in the muscular and mucosal layers, and VIP in the mucosal layer of the oviduct isthmus were all associated with the severity of the disease (P<0.05). These results suggest that decreased nerve fibers in the oviduct isthmus in women with endometriosis in comparison to women without may imply a role in the pathogenesis of endometriosis.

Abstract
Non-tubal ectopic pregnancies are a rare subgroup of ectopic pregnancies implanted at sites other than the Fallopian tube. Mortality from non-tubal ectopic pregnancies is higher compared with that for tubal ectopic pregnancies, and they are becoming more common, partly due to the rising incidence of Caesarean sections and use of assisted reproductive technologies. Non-tubal ectopic pregnancies can be especially difficult to treat. Surgical treatment is complex, and follow-up after medical treatment is usually protracted. There is therefore a need for more effective medical therapies to resolve non-tubal ectopic pregnancies and reduce operative intervention. We have recently reported successful use of combination gefitinib (an orally available epidermal growth factor receptor inhibitor) and methotrexate for treatment of tubal pregnancies. To our knowledge, this combination has not been used to treat non-tubal pregnancies. Here we report the use of combination gefitinib and methotrexate to treat eight women with stable, non-tubal ectopic pregnancies at two tertiary academic teaching hospitals (Edinburgh, UK and Melbourne, Australia); five interstitial and three Caesarean section scar ectopic pregnancies. Pretreatment serum hCG levels ranged from 2458 to 48 550 IU/l, and six women had pretreatment hCG levels >5000 IU/l. The women were co-administered 1-2 doses of i.m. methotrexate (50 mg/m² on Day 1, ± Day 4 or Day 7) with seven once daily doses of oral gefitinib (250 mg). The women were monitored until complete resolution of the ectopic pregnancy, defined as a serum hCG <15 IU/l. Time to resolution (days from first methotrexate dose until serum hCG <15 IU/l), safety and tolerability, complication rates and subsequent fertility outcomes were also recorded. All eight women were successfully treated with combination gefitinib and methotrexate. The most common side effects were transient acne/rash and diarrhoea, known side effects of gefitinib. All women promptly resumed menstruation and importantly, three women subsequently conceived spontaneously. Two have delivered a healthy infant at term and the third is currently in her second trimester of pregnancy. Hence, our case series supports a future clinical trial to determine the efficacy of combination gefitinib and methotrexate to treat non-tubal ectopic pregnancies.

Abstract
BACKGROUND Studies from knockout mice suggest that perturbations in oviductal endocannabinoid levels, endocannabinoid receptors, or endocannabinoid degrading enzyme [fatty acid amide hydrolase (FAAH)] expression result in infertility secondary to physical trapping of embryos. Similar observations have been made in ectopic pregnant women together with a suggestion that the endocannabinoid receptor gene polymorphism 1359G/A (rs1049353) is associated with ectopic pregnancy. These observations led to the hypothesis that ectopic pregnancy is associated with a perturbation in levels of endocannabinoids and FAAH activity and that such changes are associated with impaired tubal function. AIMS The objective of the study was to quantify the plasma levels of endocannabinoids (anandamide, oleoylethanolamide, and palmitoylethanolamide) and evaluate blood endocannabinoid metabolizing enzyme activities FAAH and N-acyl-phosphatidyl-ethanolamine phospholipase D (NAPE-PLD) in ectopic pregnancy and normal pregnant controls and relate that to β-human chorionic gonadotropin (β-hCG) levels. Additionally, we wanted to examine the effect of endocannabinoids on cilia beat frequency in Fallopian tube epithelial cells ex vivo. PARTICIPANTS AND METHODS Whole blood collected from ectopic and normal pregnancies was used for quantification of plasma endocannabinoid levels by ultra-HPLC-tandem mass spectrometry of FAAH and NAPE-PLD enzyme activities by radiometric assays, and β-hCG by immunoassay. Fallopian tube epithelial cells from healthy volunteers were treated with endocannabinoids and cilia beat frequency analyzed using a high-speed digital camera and CiliaFA software. RESULTS FAAH activity (P < .05) but not NAPE-PLD activity was significantly reduced in ectopic pregnancies. All 3 endocannabinoids levels were significantly higher (P < .05) in ectopic pregnancy. There was no correlation between endocannabinoids, enzyme activity, and β-hCG levels. Oleoylethanolamide (P < .05), but not methanandamide or palmitoylethanolamide, significantly decreased cilia beat frequency in Fallopian tube epithelial cells. CONCLUSION Elevated endocannabinoid levels and reduced FAAH activity are associated with ectopic pregnancy and may modulate tubal function, suggesting dysfunctional endocannabinoid action in ectopic implantation. Oleoylethanolamide may play a critical role in embryo-tubal transport.

Abstract
OBJECTIVE To investigate factors with pelvic adhesions and the effect of different degrees pelvic adhesions on fallopian tube recanalization in infertile patients. METHODS Total of 527 infertile patients undergoing hysteroscopy and laparoscopic surgery in Affiliated Hospital of Chinese People's Armed Police Forces Logistics College were studied retrospectively. According to the extent of pelvic adhesions, tubal umbrella adhesions and atresia, 377 cases were classified into adhesion groups, including 73 cases in grade I, 221 cases in grade II, 75 cases in grade III and 8 cases in grade IV based on adhesion score. The 150 cases with no obvious pelvic adhesion were matched as control group. Among 8 cases with grade IV ahesion were exluded from ahesion group the relationship between pelvic adhesions and related history, abdominal lesions, tubal patency and the prognosis were studied. RESULTS (1) Related factors: the frequency of pelvic adhesion and more than 7 years of infertility of 23.9% (88/369) in adhesion group were significantly higher than 12.0% (18/150) in control groups. (2) HISTORY: compared with the control group (12.7%, 19/150; 28.7%, 43/150; 11.3%, 17/150; 12.0%, 18/150; 17.3%, 26/150), patients with pelvic adhesions present more incidence abortion (23.6%, 87/369), uterine cavity operation (38.2%, 141/369), ectopic pregnancy (20.9%, 77/369), pelvic inflammatory disease (25.5%, 94/369) and abdominopelvic surgery (31.4%, 116/369). (3) Endoscopy exploration: the incidence of hydrosalpinx (24.7%, 91/369), tube distorted (15.7%, 58/369) and salpingostomy (72.9%, 269/369) in adhesion group were higher than those in control group (2.0%, 3/150; 4.0%, 6/150; 12.0%, 18/150), but relatively lower incidence of pelvic endometriosis lesions (5.7%, 21/369) and mesosalpinx cysts (16.3%, 60/369) than those in control group (16.0%, 24/150; 30.0%, 45/150). The rate of proximal tubal recanalization (59.5%, 91/153) in adhesion group was lower than 75.4% (52/69) in control group. However, the rate of distant tubal recanalization of 84.4%, (281/333) in adhesion group and; 13/15 in control group didn't show statistical difference. (4) PROGNOSIS: the rate of ectopic pregnancy of 9.7% (29/299) in adhesion group was significantly higher than 3.1% (4/128) in control group. Among cases with grade III adhesion exhibited the highest rate of ectopic pregnancy (13.0%, 7/54; OR = 4.62, 95%CI: 1.29 - 16.50). (5) Multivariate analysis: it was found that more than two drug abortions (OR = 3.29, 95%CI: 1.34 - 8.07), pelvic and(or) abdominal surgery history (OR = 2.20, 95%CI: 1.35 - 3.57) and pelvic inflammatory disease history (OR = 1.54, 95%CI: 1.21 - 1.97) were risk factors with pelvic adhesions. CONCLUSION More than or equal to two drug abortion history, pelvic inflammatory disease and pelvic and abdominal surgery damage were important factors for pelvic adhesions of infertility patients, which may decrease the possibility of proximal tubal recanalization and increase ectopic pregnancy risk.

Abstract
The WHO classification's concept "infertility of unclear genesis" is due to a number of circumstances. On the one hand, this is a preponderance of the subtle forms of diseases, which are a cause of female infertility, including the subclinical forms of small pelvic inflammatory diseases (SPID). On the other hand, this is an imperfection of existing diagnostic methods. Laparoscopy considered to be the gold standard demonstrates a not very high efficiency in diagnosing SPID because of its low sensitivity. In practice, laparoscopic diagnosis of SPID is combined with ultrasound study, computed tomography, and magnetic resonance tomography. This paper proposes to use optical coherent tomography (OCT) in addition to laparoscopy. OCT makes it possible to noninvasively in real time obtain information on the internal structure of biological tissues with a resolution of 10-15 pm at a depth of at least 2 mm. Removable endoscopic probes make OCT compatible with standard endoscopic studies. The use of OCT during laparoscopy yielded optical images of the internal structure of the fallopian tube wall in different conditions: unaltered fallopian tubes; an acute inflammatory process with pronounced changes; minimal manifestations of fallopian tube inflammatory changes. Based on the comparative analysis of OCT data and histological findings, the authors elaborated OCT criteria for health and disease. A blind test indicated the high diagnostic efficacy of the technique. The additional processing of images makes it possible to objectify the data and to automate the optical introscopic technique proposed by the authors.

Abstract
OBJECTIVE To investigate the accuracy of transvaginal three-dimensional hysterosalpingo-contrast sonography using SonoVue (3D SonoVue-HyCoSy) in the assessment of Fallopian tubal patency. METHODS We recruited 75 infertile patients undergoing 3D SonoVue-HyCoSy before standard diagnostic laparoscopy with chromotubation (lap and dye). Tubal patency was assessed by automated 3D coded contrast imaging (3D SonoVue-HyCoSy), and the findings were compared with the results of lap and dye. RESULTS For detecting tubal patency among the 150 Fallopian tubes assessed, 3D SonoVue-HyCoSy had a sensitivity of 93.5%, specificity of 86.3%, positive and negative predictive values of 87.8% and 92.6%, respectively, and diagnostic accuracy of 90.0%. The test-positive rates of 3D SonoVue-HyCoSy vs lap and dye were not significantly different (82/150 vs 77/150, P > 0.05). CONCLUSION 3D SonoVue-HyCoSy should be considered clinically valuable as a practical, non-invasive, primary investigatory tool for evaluating tubal patency.

Abstract
We performed this retrospective case-control study analyzing 428 first-attempt in vitro fertilization (IVF) cycles, among which 254 involved women with a previous or present diagnosis of ovarian endometriosis. First, the results of these 254 cycles were compared with 174 cycles involving patients with proven non-endometriotic tubal infertility having similar age and body mass index. Women with ovarian endometriosis had a significantly higher cancellation rate, but similar pregnancy, implantation and delivery rates as patients with tubal infertility. Second, among the women with ovarian endometriosis, the women with a history of laparoscopic surgery for ovarian endometriomas prior to IVF and no visual endometriosis at ovum pick-up (n = 112) were compared with the non-operated women and visual endometriomas at ovum pick-up (n = 142). Patients who underwent ovarian surgery before IVF had significantly shorter period, lower antral follicle count and required higher gonadotropin doses than patients with non-operated endometriomas. The two groups of women with a previous or present ovarian endometriosis did, however, have similar pregnancy, implantation and live birth rates. In conclusion, ovarian endometriosis does not reduce IVF outcome compared with tubal factor. Furthermore, laparoscopic removal of endometriomas does not improve IVF results, but may cause a decrease of ovarian responsiveness to gonadotropins.

Abstract
OBJECTIVE To review the published literature, outline the pathogenesis of failed sterilization and discuss the currently available contraceptive options once sterilization fails. STUDY DESIGN Publications from January 1966 to October 2008 and indexed in the MEDLINE/PubMed database were reviewed. Medical search heading words sterilization, sterilization failure, sterilization methods and contraception were used to identify relevant articles. In addition, references were obtained through cross-referencing the bibliography cited in each work. RESULTS Available evidence suggests that sterilization fails in 0.13-1.3% of sterilization procedures and of these, 15-33% will be ectopic pregnancies. Tubal recanalization and cornual and tuboperitoneal fistula formation are the main causes; their occurrence can be reduced by proper training and use of appropriate sterilization techniques. Following sterilization failure, hysterosalpingography can provide valuable information about the patency of the fallopian tubes. CONCLUSION Tubal sterilization is highly effective but can fail. There is a paucity of information in the literature as to what is best or most appropriate for patients when sterilization fails. Patients should be counseled at the outset about the contraceptive options that are available should sterilization fail.

Abstract
OBJECTIVE To evaluate the effect of different grades of pelvic inflammatory disease (PID) and of salpingectomy on outcomes of in vitro fertilization-embryo transfer (IVF-ET). METHODS Two hundred and twenty three cycles of IVF-ET were divided into three groups, including mild group, moderate group and severe group, according to different grades of sequelae of PID finding in exploratory operations before IVF. Patients in each group were divided into two subgroups according to receiving salpingectomy or not. The data of total dose of gonadotrophin (Gn), oocyte number, low response rate, fertilization rate, good embryo number and pregnancy rate were analysed between three groups and the two subgroups of each group, respectively. RESULTS All parameters were related to PID grades except fertilization rate. The total dose of Gn, oocyte number, good embryo number, low response rate and pregnancy rate were (2057 +/- 503) IU/L, (16 +/- 6), (6.0 +/- 4.3), 4.2%, 63.9% in mild group; (2204 +/- 603) IU/L, (12 +/- 6), (4.5 +/- 3.5), 13.9%, 46.8% in moderate group; and (2372 +/- 1018) IU/L, (9 +/- 6), (3.1 +/- 2.9), 33.8%, 41.2% in severe group. The total dose of Gn and low response rate increased with the aggravation of the grades of PID (P < 0.05). The oocyte number, good embryo number and pregnancy rate also had significant differences between three groups (P < 0.01, P < 0.01, P < 0.05, respectively). In mild and severe groups, the salpingectomy had no contribution to the outcome of IVF-ET treatment. In moderate group, patients receiving salpingectomy had more oocytes and good embryos and higher pregnancy rate than the others who retained oviducts (P < 0.05). CONCLUSIONS Grades of PID have an adverse effect on IVF-ET outcomes. Receiving salpingectomy or not should be based on different grades of PID, but operations of ovary-free should be performed in all patients.

Abstract
Isolated torsion of the fallopian tube without ovarian involvement and associated pathology is a rare event. We report an 18-year-old single female who presented with acute lower abdominal pain during menstruation after a minor trauma of the pelvis. It was diagnosed as isolated torsion of normal right tube during laparatomy due to herniation of the tube through a tear in the broad ligament.

Abstract
The aim of this study was to assess the diagnostic value and the usefulness of sono hysterosalpingography (SHG) in the detection of uterine abnormalities and tubal patency, compared with other diagnostic methods among patient with infertility. In a prospective study, 86 patients in the initial stage of the infertility treatment were examined by SHG using saline NaCl infundibular and Echovist as contrast media. Further status of the tubes and uterine cavity was assessed by the "gold standards", laparoscopy and hysteroscopy. Sensitivity, specificity, positive predictive value and the negative predictive value of SHG using NaCl infundibular for evaluation of the uterine cavity were 98.8%, 92.5%, 91.4% and 92%, respectively. Sensitivity, specificity, positive predictive value and the negative predictive value of SHG for the assessment of the tubal status were 97.6%, 89.2%, 76.3% and 77.4%, respectively. There were no evident complications during or after the procedure. Sono hysterosalpingography is useful in making decisions regarding further procedures for the diagnosis and treatment of infertility. This method is simple, safe and cheap for early assessment of the reproductive status of uterine cavity and fallopian tubes and perspective as a routine, first-line infertility investigation.

Abstract
CONTEXT AND OBJECTIVE As there is little information about fertility outcomes among women following clinical treatment (methotrexate and expectant management) and surgery (salpingectomy) consequent to ectopic pregnancy, we evaluate the results from hysterosalpingography subsequent to treatment. The objective was to evaluate contralateral tubal patency using hysterosalpingography following surgery and clinical treatment of tubal pregnancy. DESIGN AND SETTING This was a prospective study at the Department of Obstetrics of Universidade Federal de São Paulo, a tertiary center. METHOD Among 115 patients who underwent hysterosalpingography following surgery and clinical treatment of tubal pregnancy between April 1994 and February 2002, 30 were treated with a single intramuscular dose of methotrexate (50 mg/m(2)), 50 were followed up expectantly and 35 underwent salpingectomy. RESULTS The patency of the ipsilateral tube was 84% after methotrexate treatment and 78% after expectant management. In addition, contralateral tubal patency was 97% after methotrexate treatment, 92% after expectant management and 83% after salpingectomy. There were no statistically significant differences between the clinical treatment and surgery groups. CONCLUSIONS The findings from this study suggest similar contralateral tubal patency rates following salpingectomy, methotrexate treatment and expectant management.

Abstract
OBJECTIVES To evaluate and compare the diagnostic value of hysterosalpingography (HSG) and laparoscopic chromopertubation (LCP), in the diagnosis of fallopian tube patency. DESIGN A comparative prospective study. SETTING The infertility clinic of the Department of Obstetrics and Gynaecology, Ga-Rankuwa hospital (Medical University of Southern Africa), Pretoria, South Africa. SUBJECTS Fifty patients were initially diagnosed with either unilateral or bilateral tubal block using HSG. Six to eight weeks later the same women were subjected to LCP to assess tubal patency. MAIN OUTCOME MEASURES Diagnostic accuracy of HSG to establish tubal patency, site of occlusion and the presence of other pathologies was compared with results obtained after laparoscopic chromopertubation (LCP). RESULTS Hysterosalpingography diagnosed bilateral proximal, bilateral distal and mixed (i.e. one side proximal and the other distal) tubal occlusion in 15(40.5%); 13(35.1%) and five (13.5%) cases respectively. Diagnostic laparoscopy confirmed the above sites of occlusion in nine (24.3%), 71(45.9%) and three (8.1%) cases. Laparoscopy detected bilateral tubal patience in three (8.1%) patients, in whom HSG had diagnosed tubal occlusion. USG was able to detect peritubal Adhesion in only four (10.8%) patients as compared with 11 patients when LCP procedure was used. In comparison with HCP, hysterosalpingography demonstrated 70% specificity for accurately diagnosing proximal tubal occlusion. CONCLUSION On a comparative scale, HSG demonstrated reduced positive predictive value especially for bilateral proximal tubal occlusion. However, in spite of its relatively limited value for accurately identifying tubal patency, HSG should still serve as a useful primary investigation.

Abstract
INTRODUCTION The role of defective fimbrio-ovarian relation in cases of unexplained infertility has not been extensively studied. The aim of the study was to assess the role of fimbrio-ovarian relation as an investigative modality in women with unexplained infertility. We also aimed to evaluate the efficacy of superovulation and freeing the fimbria-ovarica in increasing the conception rate of women with unexplained infertility. MATERIALS AND METHODS This was a prospective study where out of 80 infertile couples, 19 women with unexplained infertility were recruited as study group. Fifteen fertile women were recruited as control group. During laparoscopy the length of the fimbria-ovarica and the ovulation border was measured. The fimbrio-ovarian accessibility test was demonstrated by holding the tubal fimbria by a non-traumatizing grasper and their ability to reach or cover the ovulation site. The freeing of the fimbria-ovarica was done, if its length was less than 2 cm. All cases were given ovulation induction for consecutive six cycles and were followed up to document any conception. RESULTS The mean length of the fimbria-ovarica was significantly less in patients with unexplained infertility (2.5 +/- 0.6 vs. 3.55 +/- 0.8 cm). The mean length of the ovulation border was not significantly different in cases and controls (2.95 +/- 0.6 vs. 3.55 +/- 0.5 cm). The fimbrio-ovarian accessibility test was positive in 6 (31.5%) cases and in 14 (93%) controls. The fimbrio-ovarian accessibility test was negative in 13 (68.4%) cases and in 1 (7%) control. Out of the 13 cases with negative FOAT, 7 had fimbrial length less than 2 cm and in whom the freeing of fimbria-ovarica was done because of severe resistance during stretching. Out of 7 patients in whom freeing of fimbria-ovarica was done 3 conceived (42.8%). Out of the 12 patients who got only ovulation induction 3 conceived (25%). CONCLUSION Fimbrio-ovarian accessibility test appears to be a promising investigative modality to assess ovarian pick-up in patients with unexplained infertility. Correcting fimbrio-ovarian relation (freeing short fimbria-ovarica) improves pregnancy rate in women with unexplained infertility.

Abstract
Fallopian tube carcinoma is the least common of gynecological malignancies. We report the case of a 56-year-old woman who presented with a 2 1/2-year history of intermittent vaginal bleeding and lower abdominal pain. Transvaginal sonography revealed a cystic lesion of the fallopian tube with papillary projections, distinct from the ovary and uterus. Doppler examination showed low vascular impedance (resistance index 0.50, pulsatility index 0.80). The suspicion of tubal malignancy was confirmed at surgery.

Abstract
Tobacco smoking is often studied as a risk factor in epidemiology. The impact on fertility and pregnancy is significant. At conception, maternal smoking may have an effect on the occurrence of ectopic pregnancy. Experimental studies on hamsters show interactions between tobacco and the oviduct. These interactions may explain the role of tobacco in ectopic pregnancy. Eleven case-control studies compared smoking in two groups of women: a cases group with ectopic pregnancy, and a control group. Ten of them found a relationship between tobacco smoking and ectopic pregnancy (increased relative risk). Considering this results, we must encourage women to reduce or better to stop smoking.

Abstract
The aim of this study was to investigate the effect of human hydrosalpinx fluid (HF) on the development and blastulation of mouse embryos and the role of the concentration of growth factors in culture medium with and without HF. In total, 2100 mouse embryos were cultured. Female mice were induced to superovulate and then mated with males. Two-cell-stage embryos were recovered from the oviduct and cultured in Ham's F-10 medium with bovine serum albumin and HF. Epidermal growth factor (EGF) and insulin-like growth factor-I (IGF-I) were analyzed by quantitative enzyme immunoassay. Mean blastulation index of 1.11, 0.97 and 0.98 was found at HF concentration of 5%, 20% and 30%, respectively (p = 0.8). The mean value of EGF in the control culture medium without HF was 11.2 pg/ml, which was statistically significantly different from that in culture medium containing HF (p < 0.001). The mean value of IGF-I in the control group without HF was 1.30 pg/ml and was not statistically significantly different from that in culture medium containing HF. Development of the two-cell-stage embryos was not affected at low (< 30%) HF concentrations. In conclusion, the present study demonstrates that even apparently normal blastulation is affected by any concentration of HF because of low embryonic EGF.

Abstract
Ectopic pregnancy is a major reproductive health issue. Although other underlying causes remain largely unknown, one cause of ectopic pregnancy is embryo retention in the fallopian tube. Here we show that genetic or pharmacologic silencing of cannabinoid receptor CB1 causes retention of a large number of embryos in the mouse oviduct, eventually leading to pregnancy failure. This is reversed by isoproterenol, a beta-adrenergic receptor agonist. Impaired oviductal embryo transport is also observed in wild-type mice treated with methanandamide. Collectively, the results suggest that aberrant cannabinoid signaling impedes coordinated oviductal smooth muscle contraction and relaxation crucial to normal oviductal embryo transport. Colocalization of CB1 and beta2-adrenergic receptors in the oviduct muscularis implies that a basal endocannabinoid tone in collaboration with adrenergic receptors coordinates oviductal motility for normal journey of embryos into the uterus. Besides uncovering a new regulatory mechanism, this study could be clinically relevant to ectopic pregnancy.

DESIGN Prospective observational study. SETTING University-based Obstetrics and Gynecology Department. PATIENT(S) Ten women undergoing laparoscopic salpingectomy for tubal pregnancy. INTERVENTION(S) The mucosal layer was isolated from the implantation and nonimplantation sites of the oviduct tissue with ectopic gestation. Semiquantitative reverse transcriptase-polymerase chain reaction was performed. MAIN OUTCOME MEASURE(S) The differences in the mRNA expression of VEGF and its receptors between the implantation and nonimplantation sites of the oviduct tissue. RESULT(S) The mRNA expression of VEGF and its receptors, both KDR and flt-1, was significantly higher in the implantation site of the human oviduct with ectopic gestation compared with the nonimplantation site. CONCLUSION(S) The results suggest that VEGF may be the angiogenic factor responsible for the implantation and placentation of an ectopic pregnancy in the oviduct.

Abstract
BACKGROUND The value of tubal perfusion pressures assessed during selective salpingography and tubal catheterization in predicting fertility has not been investigated. METHODS A total of 325 infertile women underwent selective salpingography and tubal catheterization. Pregnancy information was collected in 256 (78.7%). The 50th (300 mmHg) and 90th (500 mmHg) centiles of the tubal perfusion pressure distribution in women with normal tubes on selective salpingography were used as thresholds. Women were divided into three tubal perfusion pressure groups: good (both tubes <300, or one tube <300 and the other 300-500 mmHg), mediocre (both tubes 300-500, or one tube <300 and the other >500 mmHg) and poor (both tubes >500, or one tube > 500 and the other 300-500 mmHg). RESULTS The pregnancy rate in the good perfusion pressure group was significantly higher than that in the poor perfusion pressure group, both when all non-IVF/ICSI first conceptions (P = 0.001) as well as when spontaneous first conceptions only were considered (P = 0.010). The pregnancy rate in the mediocre group lay between the good and the poor groups, though none of the comparisons reached statistical significance. CONCLUSIONS Selective salpingography can provide additional diagnostic information in comparison with other tubal assessment tests. Tubal perfusion pressures may be predictive of future fertility.

Abstract
BACKGROUND There are many published case reports of successful conception following transcervical Fallopian tube recanalization (T-FTR) in patients with bilateral proximally occluded Fallopian tubes. However, no serial trials have been published with respect to successful conception following unilateral tubal recanalization in infertile patients with a unilateral proximally occluded tube and a contralateral patent tube. This study was designated to analyse the success rate of T-FTR and the pregnancy rate due to natural fertilization in the lumen of the recanalized tube in these patients. METHODS We have encountered only 11 patients with this abnormality in our department in the past 10 years. T-FTR with fluoroscopic guidance was performed in these patients, confirmed by at least two hysterosalpingographies to exclude tubal spasm. The uterine catheter devised by us was used during the procedure. RESULTS All 11 Fallopian tubes were successfully opened by T-FTR. In the six patients who conceived, a preovulatory follicle was demonstrated on the side of the cannulated tube during the conception. The success rate of recanalization, the pregnancy rate due to fertilization in the lumen of the recanalized tube and the successful delivery rate were 100, 55 and 36% respectively. CONCLUSIONS Our findings suggest that a functional and/or organic disorder in the patent tube resulted in infertility in patients with unilateral proximal tubal obstruction. Our results further show that recanalization of occluded tubes is an effective treatment. Thus, recognition of successful conception following T-FTR in these patients will be beneficial to our clinical approach to this infertile condition.

Abstract
Hysterosalpingoscintigraphy (HSSG) is a simple method to evaluate the transport function of uterus and fallopian tubes. There is a quick uptake of radionuclides into the uterus and a transport to the side bearing the dominant follicle in 70 % of the patients in the late follicular phase of the cycle. Uptake and transport of the immotile radionuclides imitate the directed sperm transport through the female genital tract at the time of ovulation. 214 of 796 infertility patients with proven patency of fallopian tubes (27 %) showed only an uptake of the particles without a transport towards the fallopian tubes (negative HSSG). In these patients no spontaneous pregnancy occurred and pregnancy rate remained low by the means of timed intercourse or insemination. Indeed, the pregnancy rate (8.4 %) was significantly lower compared with the patients who became pregnant by timed intercourse, insemination or spontaneously and had a positive HSSG before (15 %; p=0.001). However, the pregnancy rate that could only be achieved by methods of ART was significantly higher in the group of patients with negative HSSG (57 % vs. 25 %, p=0.05). Our data suggest that HSSG is a new method to evaluate the integrity of the inner genital tract's transport function, especially in patients suffering from idiopathic infertility. Impaired transport function (negative HSSG) should be considered as an indication for IVF-treatment.

Abstract
The purpose of this study was to determine diagnostic accuracy of hysterosalpingography by using different diagnostic criteria in peritubal adhesion diagnosis. The authors retrospectively reviewed cases in which both hysterosalpingography and laparoscopy were performed. Fifty-nine of 84 cases had laparoscopy proved peritubal adhesion. Five hysterosalpingographic signs (convoluted tube, vertical tube, ampullary dilatation, peritubal halo and loculation of the spillage of contrast material) defined by Karasick and Goldfarb were used to diagnose peritubal adhesion. All cases were analyzed by two different diagnostic criteria: first diagnostic criterion, presence of one or more signs means abnormal; second diagnostic criterion, presence of two or more signs means abnormal. Peritubal adhesion was diagnosed in 70 of 84 cases by using the first diagnostic criterion, 53 of 84 cases by using the second diagnostic criterion. The first diagnostic criterion displayed 94.9 per cent sensitivity, 44 per cent specificity, 80 per cent positive predictive value, 79.76 per cent accuracy and the likelihood ratio of 1.69. The second diagnostic criterion showed 74.6 per cent sensitivity, 64 per cent specificity, 83 per cent positive predictive value, 71.43 per cent accuracy and the likelihood ratio of 2.07. The authors conclude that using the 2nd diagnostic criterion is more appropriate than using the 1st diagnostic criterion in diagnosing peritubal adhesion.

Abstract
We investigated the influence of pelvic endometriosis and ovarian endometrioma on pregnancy outcome in women associated with infertility. A total of 237 women with endometriosis were reviewed, and their fertility rate was assessed by both r-AFS staging and TOP classification as previously proposed by our group. There was no significant difference in pregnancy rate among r-AFS stages. However, the pregnancy rate was mostly affected by the tubal condition according to the TOP classification as follows: no adhesive lesion (T0), 53% (69/129); unilateral lesion (T1), 46% (18/39); bilateral lesion with at least one tube patent, (T2), 37% (10/27); bilateral tubal occlusion (T3), 0% (0/8) (p < 0.05, Mantel-Extension test). The absence (O0-O1) or co-existence (O2-O3) of ovarian endometrioma and different gradings of cul-de-sac obliteration (P2-P3) showed no significant differences in pregnancy rate. The resulting conception rate was also not affected by the size or location of ovarian endometrioma. In addition, the higher adhesion score of ovarian endometrioma involving the fallopian tube and as described in r-AFS classification had a significant detrimental effect on fertility. These observations suggest that our TOP classification describing individual tubal condition has a clinically predictive value in assessing the reproductive outcome of women with endometriosis.

Abstract
Ciliogenesis in human oviduct epithelium was studied with transmission and scanning electron microscopes. Both centriolar and acentriolar pathways were involved in duplication of centrioles. The plasma membrane surrounding the base of new cilia invaginated toward the distal end of the basal body during formation of transitional fibers. Fibrous granules were involved in development of striated rootlets in addition to formation of centrioles. The tips of rootlets elongated in fibrils with a banding pattern different from that of usual rootlets; further the fibrils' tips were laterally connected to cell organelles (mostly mitochondria). Ciliogenic cells in early stages contained secretory granule-like vesicles, suggesting that ciliogenic cells are differentiated from secretory cells. The ordinary course of ciliogenesis was disturbed in some ciliogenic cells, resulting in formation of various ciliary abnormalities. Intracytoplasmic ciliated cysts, cilia within periciliary sheaths, and intracytoplasmic axonemes were formed due to disturbance of migration of duplicated centrioles. Swollen cilia and some compound cilia were developed during ciliary elongation.

Abstract
OBJECTIVES Reproductive outcome after laparoscopy or laparotomy performed for treatment of ectopic pregnancy. METHODS Data of 104 women were collected by a questionnaire and from medical records. RESULTS No differences in pregnancy rate were found comparing the two different operative procedures. Women with a normal contralateral fallopian tube had a better pregnancy rate compared with those with a damaged contralateral tube. CONCLUSIONS The crucial factor for future reproductive outcome after surgical treatment of ectopic pregnancy is the status of the contralateral tube.

Abstract
97 females at reproductive age with chronic nonspecific salpingo-oophoritis (CNSO) were examined and treated. The results of the treatment (vaginal and external impact) demonstrate positive effects of various cryotherapeutic techniques on CNSO clinical course, on hormonal and immune unbalance, functional activity of the uterine tubes, regional hemodynamics, psychoemotional status. Thus, cryotherapy is an effective adjuvant in combined therapy of CNSO.

Abstract
OBJECTIVE To assess the frequency of infertility after pelvic inflammatory disease (PID) and factors important in postinfectious tubal damage in an urban population at high risk for sexually transmitted diseases. METHODS From a cohort of 213 women with PID documented by laparoscopy and/or endometrial biopsy, 58 women (27% of the initial cohort) were interviewed by phone 2 to 9 years after an index episode of PID. Data regarding the initial history, physical examination, microbiology, laparoscopic, and serologic findings, and data concerning interval contraception, subsequent pregnancy, subsequent infection, and chronic pelvic pain were compared among those with and without infertility at follow up. RESULTS Nineteen (40%) of the 48 women not using contraception were involuntarily infertile after the index episode of PID. Compared with those who had an interval pregnancy, infertile women were older (P = 0.02), more likely to have a history of infertility prior to the index episode of PID (P = 0.001), and were more likely to have occluded or partially occluded fallopian tubes (P = 0.03), peritubal adhesions (P = 0.007), or perihepatic adhesions (P = 0.02) seen by laparoscopy performed during the index episode. Surprisingly, recovery of Chlamydia trachomatis was negatively related to infertility (P = 0.001), although a similar proportion of both groups had chlamydia immunoglobulin M antibody (40% vs. 31%). Chlamydia heat shock protein was weakly related to infertility (P = 0.08). The isolation of Neisseria gonorrhoeae was not significantly different between groups (53% vs. 57%). CONCLUSIONS The high rate of postinfection infertility found was probably related to a combination of tubal damage before and during the index episode of PID. Prevention of recurrent PID and better understanding of the pathophysiology of postinfection tubal damage (which may differ between chlamydia and gonorrhea) is needed to develop more effective strategies to reduce permanent tubal damage.

Abstract
OBJECTIVE To evaluate operative course, tubal patency and reproductive performance after laparoscopic treatment of ectopic pregnancy in relation to initial human chorionic gonadotropin (hCG) values and to the kind of operation. DESIGN Retrospective study. PATIENTS Fourty-five patients affected by ectopic pregnancies: thirty-two treated with laparoscopic linear salpingotomy subvided into two groups depending on the hCG serum values < 10,000 mUl/ml (twenty patients: group 1) or > 10,000 mUl/ml (twelve patients Group 2), thirteen patients (Group 3) undergoing laparoscopic salpingectomy. Hysterosalpingographic examination was performed two or three months after surgery. MAIN OUTCOME MEASURES Operative time, major surgical complications, tubal patency and pregnancy rate after surgery. RESULTS Operative time was significantly (p < 0.05) lower in both group 1 and 3 (22.5 +/- 3.2 and 19.1 +/- 6.3, respectively) than in group 2 (39.4 +/- 5.6). Bilateral patent tubes were observed in eighteen cases of group 1 (90%) and eight cases of group 2 (60%). No statistically significant differences were found between the pregnancy rate of both group 1 (8/18) and 2 (3/8) and of group 3 (3/11). CONCLUSIONS Reproductive outcome is similar in both conservative and destructive laparoscopic management of ectopic pregnancy: furthermore it shows a trend of improvement, not statistically significant, in conservative treatment.

Abstract
OBJECTIVE To study tubal patency and fertility outcome of patients with expectantly managed ectopic pregnancy (EP). DESIGN A prospective study. SETTING Department of Obstetrics and Gynecology, Turku University Central Hospital, Turku, Finland. PATIENT(S) Thirty patients who wanted to become pregnant again were treated successfully by expectant management of EP. INTERVENTION(S) Patients were examined with posttreatment hysterosalpingography, and they filled out a questionnaire about their subsequent pregnancies. MAIN OUTCOME MEASURE(S) Free passage through open lumen showing tubal patency; number of full-term pregnancies and EPs revealing relative rate of subsequent fertility. RESULT(S) A free passage through the diseased tube was seen in 93% of the cases (28 of 30). Two of the 24 patients (8.4%) who wanted to become pregnant had an obstruction in the diseased tube. One (4.2%) of them had a normal opposite tube and later had a normal pregnancy. The other (4.2%) had an obstruction in both tubes and subsequently had a repeat EP. One of the 6 patients had an EP (this patient did not want to become pregnant and did not use contraception). However, her posttreatment hysterosalpingography was normal. In total, the subsequent pregnancy rate was 88% (21 of 24), and the rate of repeat EP was 4.2% (1 of 24). CONCLUSION(S) Patients who are treated with expectant management have a good long-term fertility outcome. Spontaneous regression of EP does not lead to increased harm or damage to the tube, i.e., the risk for repeat EP is low.

Abstract
This study was conducted to determine whether the additional use of pulsed wave Doppler improves the diagnostic capacity in assessing tubal patency by hysterosalpingo contrast sonography (HyCoSy). A total of 210 women with a history of infertility were included in this study. HyCoSy was performed after intrauterine injection of Echovist 200. For the assessment of tubal patency B-mode scanning and pulsed wave Doppler ultrasound were performed in the proximal and distal tubal segments. With the combined sonographic procedure 297 tubes (74%) were rated patent, 35 (8%) incompletely obstructed and 70 (18%) completely obstructed. A total of 252 tubes were additionally examined by laparoscopy for reference purposes. Concordant results for both methods were found in 92% of tubes, nine had been rated false negative and 10 tubes appeared to have been rated false positive. The combined sonographic specificity was found to be 85% with a sensitivity of 95%. Peritubal adhesions detected by laparoscopy were found to be the reason for false positive sonographic results in 60% of cases. In conclusion, the combined B-mode and pulsed wave Doppler examination appears to be a non-invasive and low-cost test for the assessment of tubal patency, which should be performed during diagnostic work-up for infertility.
