Abstract
OBJECTIVE Previous work has suggested that the ultrasound-based benign simple descriptors (BDs) can reliably exclude malignancy in a large proportion of women presenting with an adnexal mass. This study aimed to validate a modified version of the BDs and to validate a two-step strategy to estimate the risk of malignancy, in which the modified BDs are followed by the Assessment of Different NEoplasias in the adneXa (ADNEX) model if modified BDs do not apply. METHODS This was a retrospective analysis using data from the 2-year interim analysis of the International Ovarian Tumor Analysis (IOTA) Phase-5 study, in which consecutive patients with at least one adnexal mass were recruited irrespective of subsequent management (conservative or surgery). The main outcome was classification of tumors as benign or malignant, based on histology or on clinical and ultrasound information during 1 year of follow-up. Multiple imputation was used when outcome based on follow-up was uncertain according to predefined criteria. RESULTS A total of 8519 patients were recruited at 36 centers between 2012 and 2015. We excluded patients who were already in follow-up at recruitment and all patients from 19 centers that did not fulfil our criteria for good-quality surgical and follow-up data, leaving 4905 patients across 17 centers for statistical analysis. Overall, 3441 (70%) tumors were benign, 978 (20%) malignant and 486 (10%) uncertain. The modified BDs were applicable in 1798/4905 (37%) tumors, of which 1786 (99.3%) were benign. The two-step strategy based on ADNEX without CA125 had an area under the receiver-operating-characteristics curve (AUC) of 0.94 (95% CI, 0.92-0.96). The risk of malignancy was slightly underestimated, but calibration varied between centers. A sensitivity analysis in which we expanded the definition of uncertain outcome resulted in 1419 (29%) tumors with uncertain outcome and an AUC of the two-step strategy without CA125 of 0.93 (95% CI, 0.91-0.95). CONCLUSION A large proportion of adnexal masses can be classified as benign by the modified BDs. For the remaining masses, the ADNEX model can be used to estimate the risk of malignancy. This two-step strategy is convenient for clinical use. © 2022 The Authors.

Abstract
Abstract
Study question
Does fertilization rate (FR) affect cumulative success rates in assisted reproduction cycles?
Summary answer
These data indicate a positive association between FR with CLBR suggesting the predictive clinical relevance of this parameter and its adoption as Key Performance Indicator(KPI).
What is known already
Numerous studies have aimed at characterizing outcome predictors. Maternal age is historically and correctly recognized as the single most important factor impacting on the clinical outcome of ART. More recently ovarian response has also gained interest in this respect. However, the quest for novel, more comprehensive predictive factors is not over; new relevant evidence is starting to emerge. FR is a noteworthy parameter because expressing a fundamental aspect of both oocyte and sperm developmental competence. In fact it has been adopted as a key performance indicator of the IVF laboratory, to assess laboratory, operator, and gamete competence.
Study design, size, duration
Reported data concern a retrospective cohort study carried out between 2015 to 2017 involving 7,968 couples undergoing 9,394 complete ICSI cycles, i.e. whose all embryos were transferred or disposed.All women aged between 18-42 years were included.We excluded from analysis: surgical sperm retrieval cases, cycles resulting in neither fresh or frozen–thawed embryo transfers,cycles in which live birth were not achieved, but with remaining cryopreserved embryos,cycles of PGT, cycle with fertilization failure and standard IVF cycles.
Participants/materials, setting, methods
The cohort was groupped according to fertilization rate intervals based on recommendations of the Vienna Consensus (<65% - Group 1; 65%-80% - Group 2; >80% - Group 3). Harnessing the large size of the original dataset, further cycle stratifications were carried out based on female age (<34, 35-38, 39-42 years) and number of oocytes retrieved (5-7, 8-10, >10 oocytes).
Main results and the role of chance
No significant difference in female age was observed between fertilization rate groups (p = 0.640). CLBR was progressively higher in relation fertilization rate in Groups 1, 2 and 3 (20.1%, 34.7%, 41.3%, P < 0.001, respectively). Number of recovered oocytes, embryo number per cycle, cumulative pregnancy rate followed the same trend (p < 0.001). The decrease in CLBR with increasing female age was significantly correlated with fertilization rate and CLBR in all three female age groups (P < 0.001). Finally, to further control for possible patient-specific confounding factors, maternal age, number of retrieved oocytes, percent of inseminated oocytes and fertilization rate were evaluated in a multivariate logistic regression analysis. From this assessment, fertilization rate emerged as a factor independently associated with cumulative live birth rate, to a degree equivalent or higher compared with the number or retrieved oocytes.
Limitations, reasons for caution
The study design is retrospective and requires further refinement to control for factors that may impact clinical outcome.
Wider implications of the findings
These data indicate a positive association of FR with CLBR, thereby suggesting that fertilization, in addition to representing an assay for gamete quality and laboratory performance,has an independent clinical significance.Irrespective of the number of retrieved oocytes and female age, we observed that, rates of FR are positively associated with CLBR.

Assessing and validating housekeeping genes in normal, cancerous, and polycystic human ovaries. J Assist Reprod Genet 2020; 37:2545-2553. [PMID: 32729067 DOI: 10.1007/s10815-020-01901-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 07/23/2020] [Indexed: 12/13/2022] Open
Abstract
PURPOSE Housekeeping genes (HKGs), reference or endogenous control genes, are vital to normalize mRNA levels between different samples. Since using inappropriate HKGs can lead to unreliable results, selecting the proper ones is critical for gene expression studies. To this end, normal human ovaries, as well as those from patients diagnosed with ovarian endometrioid adenocarcinoma (OEA), ovarian mucinous adenocarcinoma (OMA), ovarian serous papillary carcinoma (OSPC), and polycystic ovary syndrome (PCOS), were used to identify the most suitable housekeeping genes. METHODS RNA was isolated from 5 normal human ovaries (52-79 years of age), 9 cancerous ovaries (3 OEA, 3 OMA, 3 OSPC; 49-75 years of age), and 4 PCOS ovaries (18-35 years of age) in women undergoing hysterectomy. cDNA was synthesized using a whole transcriptome kit, and quantitative real-time PCR was performed using TaqMan array 96-well plates containing 32 human endogenous controls in triplicate. RESULTS Among 32 HKGs studied, RPS17, RPL37A, PPIA, 18srRNA, B2M, RPLP0, RPLP30, HPRT1, POP4, CDKN1B, and ELF1 were selected as the best reference genes. CONCLUSIONS This study confirms recent investigations demonstrating that conventional HKGs, such as GAPDH and beta-actin, are not suitable reference genes for specific pathological conditions, emphasizing the importance of determining the best HKGs on a case-by-case basis and according to tissue type. Our results have identified reliable HKGs for studies of normal human ovaries and those affected by OEA, OMA, OSPC, or PCOS, as well as combined studies of control subjects vs. each cancer or PCOS group.

Contribution of cryopreservation to the cumulative live birth rate: a large multicentric cycle-based data analysis from the Italian National Registry. J Assist Reprod Genet 2019; 36:2287-2295. [PMID: 31463873 PMCID: PMC6885470 DOI: 10.1007/s10815-019-01566-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Accepted: 08/13/2019] [Indexed: 11/29/2022] Open
Abstract
PURPOSE To estimate the contribution of cryopreservation to the cumulative live birth rate (CLBR) after law modification in Italy in the era of vitrification and freeze-all. METHODS The Italian National Registry performed a cycle-based data collection. Nine Italian IVF clinics were involved incorporating a total of 10,260 fresh cycles performed between January 2015 and April 2016 resulting in 9273 oocyte retrievals and 3266 subsequent warming cycles from the same oocyte retrievals performed up to December 2016. Mean female age was 37 ± 4.3 years. Primary outcome measure was CLBR per oocyte retrieval. Confounding factors were tested in multivariate regression analysis, and the relative impact of cryopreservation to the CLBR in different patient categories was calculated. RESULTS CLBR per oocyte retrieval was 32.6%, 26.5%, 18.7%, 13.0%, and 5.5% for women younger than 36, aged 36-39, 40-41, and older than 41 years, respectively. The total relative contribution of oocyte/embryo cryopreservation was 40.6% (95% CI 38.41-42.75). An association between maternal age, number of oocytes retrieved, fertilization rate, cryopreservation, and cumulative live birth was shown. When adjusted for confounders, a 2.3-fold increase was observed in the chance of live birth when cryopreservation was performed (OR 2.3; 95% CI 1.99-2.56). In high responder patients (> 15 oocytes retrieved) where freeze-all was applied in 67.6% of cycles to avoid the risk of hyper stimulation syndrome, the relative contribution of vitrification to the CLBR was 80.6%. CONCLUSIONS Cryopreservation is essential in IVF and should always be available to patients to optimize success rates. Multicentric, cycle-based data analyses are crucial to provide infertile couples, clinicians, and regulatory bodies with accurate information on IVF effectiveness including fresh and cryopreserved cycles.

Influence of male human immunodeficiency virus (HIV) and hepatitis C virus (HCV) infection on the reproductive outcomes in serodiscordant couples: a case-control study. Andrology 2019; 7:852-858. [PMID: 30993859 DOI: 10.1111/andr.12623] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2019] [Revised: 03/06/2019] [Accepted: 03/07/2019] [Indexed: 01/23/2023]
Abstract
BACKGROUND Nowadays, serodiscordant couples (SDCs) with human immunodeficiency virus (HIV) or hepatitis C virus (HCV)-infected men have the chance to conceive safely, giving birth with a minimum risk of cross-infection. OBJECTIVE To assess the impact of male HIV and HCV infection on the assisted reproductive technologies (ART) outcomes in SDCs, with HIV or HCV seropositive men and negative partners. MATERIALS AND METHODS Of 153 couples: 24 in Group 1 (HIV-seropositive men), 60 in Group 2 (HCV-seropositive men) and 69 in Group 3 (controls). Sperm-washing procedure was performed using a three-step system. Fresh ICSI cycles were carried out in HIV SDCs, HCV SDCs and controls. Seminal parameters, fertilization rate (FR), cleavage rate (CR), pregnancy rate per cycle (PR/C), miscarriage rate, implantation rate (IR) and live birth rate were evaluated. RESULTS All the seropositive men have undetectable viral loads at the time of insemination, and both partners were free from co-morbid infections. The median number of embryos transferred was 2.0 (IQR 1.0-3.0), with no differences among groups. FR was significantly reduced in HIV and HCV SDCs compared to the controls (66%, 61% and 75%, respectively; p < 0.01). CR was similar between groups (p = 0.3). IR was 12.1%, 11.1% and 14.1%, respectively, in the three groups (p = 0.30). PR/C was 21.7%, 17.6% and 20.2% in HIV, HCV and controls, respectively. Live birth rate per cycle was 17.4%, 15.7% and 15.9%, respectively. There were no significant differences in clinical pregnancies per cycle, as well as miscarriages and live births (p = 0.30; 0.30; 0.60, respectively). CONCLUSIONS The sperm-washing technique with ICSI may generate a promising way to improve pregnancy outcomes and to reduce the risk of viral transmission in these couples. In this setting, we can correctly counsel HIV- and HCV-infected men of SDCs with regard to the likelihood of father their own biological child.

Abstract
BACKGROUND Several randomised controlled trials (RCTs) have investigated the usefulness of pituitary block with gonadotrophin-releasing hormone (GnRH) antagonists during intrauterine insemination (IUI) cycles, with conflicting results. OBJECTIVE The aim of the present systematic review and meta-analysis of RCTs was to evaluate the effectiveness of GnRH antagonist administration as an intervention to improve the success of IUI cycles. SEARCH STRATEGY Electronic databases (MEDLINE, Scopus, EMBASE, Sciencedirect) and clinical registers were searched from their inception until October 2017. SELECTION CRITERIA Randomised controlled trials of infertile women undergoing one or more IUI stimulated cycles with GnRH antagonists compared with a control group. DATA COLLECTION AND ANALYSIS The primary outcomes were ongoing pregnancy/live birth rate (OPR/LBR) and clinical pregnancy rate (CPR). Pooled results were expressed as odds ratio (OR) or mean differences with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroups analysis. The body of evidence was rated using GRADE methodology. Publication bias was assessed with funnel plot, Begg's and Egger's tests. MAIN RESULTS Fifteen RCTs were included (3253 IUI cycles, 2345 participants). No differences in OPR/LBR (OR 1.14, 95% CI 0.82-1.57, P = 0.44) and CPR (OR 1.28, 95% CI 0.97-1.69, P = 0.08) were found. Sensitivity and subgroup analyses did not provide statistical changes in pooled results. The body of evidence was rated as low (GRADE 2/4). No publication bias was detected. CONCLUSION Pituitary block with GnRH antagonists does not improve OPR/LBR and CPR in women undergoing IUI cycles. TWEETABLE ABSTRACT Pituitary block with GnRH antagonists does not improve the success of IUI cycles.

Clinical and ultrasound characteristics of surgically removed adnexal lesions with largest diameter ≤ 2.5 cm: a pictorial essay. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2017; 50:648-656.

Abstract
OBJECTIVES To describe the ultrasound characteristics, indications for surgery and histological diagnoses of surgically removed adnexal masses with a largest diameter of ≤ 2.5 cm (very small tumors), to estimate the sensitivity and specificity of diagnosis of malignancy by subjective assessment of ultrasound images of very small tumors and to present a collection of ultrasound images of surgically removed very small tumors, with emphasis on those causing diagnostic difficulty. METHODS Information on surgically removed adnexal tumors with a largest diameter of ≤ 2.5 cm was retrieved from the ultrasound databases of seven participating centers. The ultrasound images were described using the International Ovarian Tumor Analysis terminology. The original diagnosis, based on subjective assessment of the ultrasound images by the ultrasound examiner, was used to calculate the sensitivity and specificity of diagnosis of malignancy. RESULTS Of the 129 identified adnexal masses with largest diameter ≤ 2.5 cm, 104 (81%) were benign, 15 (12%) borderline malignant and 10 (8%) invasive tumors. The main indication for performing surgery was suspicion of malignancy in 22% (23/104) of the benign tumors and in all 25 malignant tumors. None of the malignant tumors was a unilocular cyst (vs 50% of the benign tumors), all malignancies contained solid components (vs 43% of the benign tumors), 80% of the borderline tumors had papillary projections (vs 21% of the benign tumors and 20% of the invasive malignancies) and all invasive tumors and 80% of the borderline tumors were vascularized on color/power Doppler examination (vs 44% of the benign tumors). The ovarian crescent sign was present in 85% of the benign tumors, 80% of the borderline tumors and 50% of the invasive malignancies. The sensitivity of diagnosis of malignancy by subjective assessment of ultrasound images was 100% (25/25) and the specificity was 86% (89/104). Excluding unilocular cysts, the specificity was 71% (37/52). Analysis of images illustrated the difficulty in distinguishing benign from borderline very small cysts with papillations and benign from malignant very small well vascularized (color score 3 or 4) solid adnexal tumors. CONCLUSIONS Very small malignant tumors manifest generally accepted ultrasound signs of malignancy. Small unilocular cysts are usually benign, while small non-unilocular masses, particularly ones with solid components, incur a risk of malignancy and pose a clinical dilemma. © 2016 The Authors.

Abstract
Between January 1996 and December 2001, at the Department of Gynecology, Perinatology and Human Reproduction of the University of Florence, 49 ectopic pregnancies were submitted to medical treatment. The treatment schedule consisted of the administration of 100 mg of intravenous methotrexate (MTX). The patients included in this study fulfilled the following requisites: gestational period <8 weeks; diameter of the ectopic gestational sac <4 cm; serum level of human chorionic beta-gonadotropin (beta-hCG) <5000 IU/ml; absence of clinical and ultrasound signs of tube rupture with initial hemoperitoneum; hematochemical tests compatible with chemotherapic treatment. All patients were followed with a dosage of serum beta-hCG repeated every 2-3 days after chemotherapy and with an ultrasound every 3-4 days. In case of documented success of treatment the patient was hospitalized for no more than 3 days after administration of the drug. In 1 case therapy took place in a day-hospital regimen. Medical treatment was effective in 35 patients out of 49 (71.4%) and led to negative beta-hCG in a median time of 11 days, with a range between 2 and 48 days. In the 14 non-responsive cases (28.6%), after a mean time of 6 days we proceeded to a traditional surgical approach or laparoscopy. In none of the cases did we find significant pharmacological toxicity, while in 9 patients (18.3%), severe painful symptoms appeared immediately after treatment, but resolved within 24 hours. Our results are interesting and in agreement with other experiences found in the literature. In our opinion, the advisability of a second administration in case of slow response, the comparison with an analogous intramuscular treatment, a more precise definition of the eligibility criteria, long-term follow-up of the patients, especially in case of subsequent pregnancies should all be further considered.

Abstract
BACKGROUND Gynaecological laparoscopic surgery outcomes can be compromised by the formation of de novo adhesions. This randomized, double-blind study was designed to assess the efficacy and safety of 4% icodextrin solution (Adept(®)) in the reduction of de novo adhesion incidence compared to lactated Ringer's solution (LRS). METHODS Patients undergoing laparoscopic surgery for removal of myomas or endometriotic cysts were treated with randomized solution as an intra-operative irrigant and 1l post-operative instillate. De novo adhesion incidence (number of sites with adhesions), severity and extent were independently scored at a second-look procedure and the efficacy of the two solutions compared. The effect of surgical covariates on adhesion formation was also investigated. Initial exploratory analysis of individual anatomical sites of clinical importance was progressed. RESULTS Of 498 patients randomized, 330 were evaluable (160 LRS--75% myomectomy/25% endometriotic cysts; 170 Adept--79% myomectomy/21% endometriotic cysts). At study completion, 76.2% LRS and 77.6% Adept had ≥ 1 de novo adhesion. The mean (SD) number of de novo adhesions was 2.58 (2.11) for Adept and 2.58 (2.38) for LRS. The treatment effect difference was not significant (P = 0.909). Assessment of surgical covariates identified significant influences on the mean number of de novo adhesions regardless of treatment, including surgery duration (P = 0.048), blood loss in myomectomy patients (P = 0.019), length of uterine incision in myomectomy patients (P < 0.001) and number of suture knots (P < 0.001). There were 15 adverse events considered treatment-related in the LRS patients (7.2%) and 18 in the Adept group (8.3%). Of 17 reported serious adverse events (9 LRS; 8 Adept) none were considered treatment-related. CONCLUSIONS The study confirmed the safety of Adept in laparoscopic surgery. The proportion of patients with de novo adhesion formation was considerably higher than previous literature suggested. Overall there was no evidence of a clinical effect but various surgical covariates including surgery duration, blood loss, number and size of incisions, suturing and number of knots were found to influence de novo adhesion formation. The study provides direction for future research into adhesion reduction strategies in site specific surgery.

Abstract
With the increasing demand for assisted reproductive techniques (ARTs), it is important to consider how to manage infection. Three main positive factors that contribute to successful in vitro fertilization (IVF) cycles are maternal age, the ovarian hyperstimulation protocol used, and the number and quality of transferred embryos. Negative factors include contamination and infection. This paper describes the issues relating to infection during IVF and proposes guidelines to control infection and to increase laboratory safety.

Abstract
The correct approach for endometriosis management is still unclear. This review explores recent data concerning diagnosis and treatment of endometriosis, trying to define guidelines for the most appropriate diagnostic approach and therapeutic regimen. At present, laparoscopy is still considered the gold standard in endometriosis diagnosis. The risks and the diagnostic limitations of laparoscopy and the inaccuracy of clinical examination justify the considerable efforts made to improve the diagnosis with imaging techniques. The therapeutic approach is still far from being defined as causal and focuses on management of clinical symptoms of the disease rather than on the disease itself. A first-line medical therapy should be tried in patients with pelvic pain not asking for a pregnancy. Surgical treatment is considered the best treatment for women with pain and or pelvic mass who wish to become pregnant in a short time. For infertile patients, medical therapy has a limited role. The 2 treatment options include surgery or in vitro fertilization (IVF). According to our results, it seems that correct management of infertile women with endometriosis is a combination of surgery and IVF in women who did not obtain post-surgery pregnancy spontaneously.

Abstract
PURPOSE OF INVESTIGATION To evaluate how many women required the so-called "emergency contraception" at our outpatient service and what the actual role is of this kind of pharmacological administration in interfering with ovulation and pregnancy, paying particular attention to the ethical and medico-legal aspects of this subject. METHODS During the period from 1 December 1998 to 30 November 2003, emergency contraception was prescribed to a total of 1,160 women. With regard to the contraceptives used, in most cases (1,132, 97.6%) a combined oral estrogen-progestogen pill (ethinyloestradiol 0.05 mg plus levonorgestrel 0.25 mg) was prescribed; in some cases (20 patients, 1.8%) danazol (400 mg), in four women (0.3%) a progestin-only pill (levonorgestrel 0.75 mg), and in four other women (0.3%) an intrauterine device. RESULTS It does not come out that there were any pregnancies in our study patients since none of them, who were told to come back for follow-up, were seen at our termination of pregnancy service or delivery room. CONCLUSION The "Yuzpe regimen" of a combined oral estrogen-progestogen pill has been the most commonly used method for emergency contraception. A new method recently proposed, a progestin-only pill with levonorgestrel 0.75 mg, is having better results than the previous one, with a lower incidence of side-effects and higher efficacy. Moreover, the treatment with this method does not interfere in case of a pregnancy already being carried and cannot interrupt it.

Abstract
PURPOSE OF INVESTIGATION The management of fetal ovarian cysts is still controversial despite the improvement in prenatal diagnosis with ultrasonography. Some studies suggest an aggressive management, while others opt for a conservative one. The prognosis of the majority of congenital ovarian cysts is good since they have a benign origin. Sometimes, however, complications such as torsion or rupture can occur which often require surgical intervention after delivery. In this paper we report our experience and a brief review of the literature. METHODS The authors report on 32 pregnant women in whom ultrasonography revealed the presence of an echo-rare or echo-free area in the fetal abdomen suggestive of an ovarian cyst. All women were followed-up during pregnancy with serial ultrasound examinations. Postnatal ultrasound controls confirmed the prenatal diagnosis in all cases. The diameters of the cysts ranged from 2.7 to 7.5 cm. RESULTS In the 16 cases (50%) in which the cyst diameter was below 4 cm, periodic ultrasound examinations revealed a tendency towards spontaneous regression of the cysts. In the other 16 cases (50%) in which the cyst diameter exceeded 4 cm, cystectomy was necessary due to subsequent complications (torsion in 6 cases, 37.5%, and intracystic hemorrhage in the other 10, 62.5%). CONCLUSION The most appropriate clinical approach in the management of benign feto-neonatal ovarian cysts is to adopt a wait-and-see policy, assessing the course of the condition by means of periodic ultrasound monitoring. Only when tumefactions measure more than 4 cm in diameter with attendant complications is surgical therapy indicated. Without complications, however, aspiration of the cystic contents is possible even in ovarian cysts exceeding 4 cm in diameter.

Abstract
OBJECTIVE To present pressure lavage under ultrasound guidance (PLUG) as a new therapeutic procedure for selected cases of intrauterine adhesions (IUA). DESIGN An open clinical investigation with no control group. SETTING Teaching hospital. PATIENT(S) Seven consecutive patients referred to our department for secondary amenorrhea due to IUA. INTERVENTION(S) A newly developed technique based on sonohysterography was used to monitor the effects of intrauterine injections of saline solution on the continuous accumulation of saline in the uterine cavity for the mechanical disruption of IUA. MAIN OUTCOME MEASURE(S) Lysis of intrauterine adhesions, restoration of menses, and increased pregnancy rate in infertile patients. RESULT(S) Five patients with mild IUA obtained satisfactory lysis of adhesions by the use of the PLUG technique. A second-look hysteroscopy after 1 month showed that filmy adhesions persisted in two patients with moderate IUA. These adhesions were removed successfully during hysteroscopy. Restoration of menses was obtained and has continued in all patients. Two of the three infertile patients became pregnant. CONCLUSION(S) This technique is safe and ideal as an in-office procedure. PLUG allows complete lysis in mild IUA cases, and the need for therapeutic, and possibly follow-up hysteroscopy, can be avoided. In moderate IUA cases, the procedure may represent a useful initial step in reducing the need for operative hysteroscopy.

Abstract
OBJECTIVE To evaluate the efficacy and safety of ultrasound (US) guidance as compared to laparoscopic monitoring during operative hysteroscopy. STUDY DESIGN Prospective, open study including 81 patients undergoing operative hysteroscopy under US guidance for uterine septum and submucous myoma. Clinical and surgical outcomes were compared with those in an historical control group of 45 patients undergoing the same operation under laparoscopic guidance. RESULTS US guidance proved satisfactory in all patients, and there were no complications due to insufficient visualization of the pelvic structures; in no case was conversion to laparoscopic guidance required. US scanning was most useful in determining the outer limit of the intramural component of submucous partial intramural myoma, allowing complete resection. During metroplasty, US guidance allowed extension of the resection beyond the normal limit conventionally defined by hysteroscopy; none required reintervention. By comparison, in the control group, a second attempt was required because the operation was insufficiently radical in four patients. CONCLUSION US guidance was used successfully as the only visual aid for hysteroscopic surgery, comparing favorably with laparoscopy in terms of efficacy and safety.

Abstract
OBJECTIVE The purpose of this contribution is to investigate the pathophysiology of the abnormal endometrial development in hyperstimulated IVF cycles. STUDY DESIGN In 12 IVF-patients who did not have embryo transfer because of failure of oocyte fertilization, serum values of 17 beta-estradiol, progesterone, FSH, LH, total and free testosterone, and androstenedione were measured on the pick-up day and were evaluated with respect to the values normally expressed in the day of ovulation; in the endometrial specimens collected 2 days later, at the time of embryo replacement, estrogen and progesterone receptors were immunohistochemically determined and dating by the Noyes method was performed. RESULTS 17 beta-Estradiol values are constantly higher, and progesterone levels are, only in four cases, higher than expected for the day of ovulation in a natural cycle. These hormonal patterns can only partially explain the pattern of steroid receptors: progesterone receptors are expressed sparsely both in glands and stroma, while estrogen receptors are abundant in the glands and absent in the stroma. In 11 of 12 patients an abnormal endometrial development with stromal advancement was observed: this morphological picture of the endometrium could partially be explained only in the four cases presenting high progesterone levels by serum values and endometrial receptor content of estrogen and progesterone. CONCLUSIONS The abnormal endometrial development in hyperstimulated IVF cycles could only in part be explained by estrogen and progesterone, and other factors have to be considered.

Abstract
Several tests based on semen variables have been proposed to predict the fertilization rate in the presence of male factor infertility, but their significance remains unclear. We investigated the utility of a screening test based on sperm survival (SST) to predict the outcome of in-vitro fertilization (IVF) cycles in the presence of male factor infertility. The SST was considered normal when the percentage of motile spermatozoa 24 h after oocyte insemination was > or =50%. The sperm survival test yielded abnormal results in <90% of cycles which were unsuccessful. The sensitivity of the SST was 87% and specificity 65% with a positive predictive value of 90% in the male factor group. We believe that the SST may be a useful predictor of the IVF cycle outcome and we propose its introduction into the routine preliminary evaluation of semen samples in cases of male factor infertility.

Abstract
PURPOSE This multicenter study was carried out to compare the efficacy of intrauterine insemination (IUI) and intraperitoneal insemination (IPI) associated with multiple follicular development as treatment for unexplained infertility. METHOD A total of 205 couples completed the trial. Sixty-seven couples underwent treatment with IPI (group A) and 138 couples underwent treatment with IUI (group B). RESULTS Clinical pregnancy was obtained in 23 couples in group A (pregnancy rate: 34.3%) and in 36 couples in group B (pregnancy rate: 26.1%). No significant difference was observed between group A and group B. As for the evolution of pregnancies and the incidence of twin pregnancies, no significant difference was observed between the two groups. CONCLUSIONS Because IUI and IPI allow us to obtain same results and IPI is more invasive than IUI, the latter technique can be considered the method of choice and IPI should be used when IUI is difficult to perform, as in the presence of a tight cervical canal.

Abstract
We report a case of acute abdomen due to puncture of a dermoid cyst during oocyte aspiration, which required laparotomy. A woman who had undergone an in-vitro fertilization and embryo transfer required hospitalization due to onset of an acute abdomen. An ultrasonographic scan showed a pelvic mass with the features of dermoid cyst. The patient required diagnostic laparotomy which confirmed the presence of a ruptured dermoid cyst with subsequent peritonitis.

Abstract
In the past, most cases of osseous metaplasia of the endometrium were diagnosed following removal of bone from the endometrium by dilatation and curettage and frequently subsequently treated by hysterectomy. Nowadays, management involves a suggested diagnosis by transvaginal ultrasound examination, confirmation by hysteroscopy and hysteroscopic removal of ectopic intrauterine bone. This is usually carried out under laparoscopic guidance. However, the degree of visual control provided by combined transabdominal and transrectal ultrasonography may prove sufficiently accurate for hysteroscopic guidance. In this report we describe a case of endometrial osseous metaplasia successfully managed by ultrasound-guided hysteroscopy. The advantages of our approach include reduced invasiveness, reduced costs and simultaneous visualization of the abdominal and intrauterine cavities. One limitation, however, is represented by the greater operator dependence of ultrasound guidance as compared to laparoscopy, the former requiring extensive training and state-of-the-art equipment. We suggest that ultrasound guidance for hysteroscopic removal of extensive osseous metaplasia may represent a potentially safer and more effective alternative to laparoscopy and would therefore encourage further clinical evaluation of this technique.

Abstract
BACKGROUND Bilateral vulvar edema associated with severe ovarian hyperstimulation syndrome is described for the first time. CASE A 28-year-old woman underwent gonadotropin-releasing hormone analogue and gonadotropin treatment for in vitro fertilization and embryo transfer. On day 18 of the cycle, the patient reported mild abdominal discomfort that became severe during the following four days. One the 22nd day of the cycle, bilateral ovarian enlargement and ascites were present. The vulva showed massive edema and fissures. Ovarian hyperstimulation syndrome (OHSS) therapy consisted of human albumin, lactated Ringer's solution and heparin. The vulvar edema was treated with topical hydrocortisone ointment, ice packs and topical gentamycin twice a day. After one week of treatment, the vulva was normal. CONCLUSION We think that the vulvar edema in this case was the result of decreased oncotic pressure and increased hydrostatic pressure, as occur during OHSS.

Abstract
A randomized polycentric study was programmed to establish the effects of daily administration of ferritin iron from early pregnancy to puerperium. 254 women with normal iron balance at the beginning of their pregnancy were randomized receiving no supplements or 40 mg iron daily. At the end of pregnancy iron balance was still normal only in one third of the pregnant women of the first group versus two third of the second group. 204 women who were iron-deficient received daily 40 or 120 mg of iron; in this group anemia developed less frequently (13% versus 29%) and iron balance normalized in one subject on four; the great majority of these women remained iron-deficient. Unwanted effects of minimal or mild relevance, and almost always sporadic were observed in 6.5% of cases and with the reduction or withdraw of the treatment in only 1.4% of cases. These results showed that daily administration of ferritin iron during pregnancy is effective and well tolerated; furthermore they suggest that the treatment must be done with at least 60 mg daily in women with normal iron balance and protracted also after the puerperium in iron deficient subjects.
