Abstract
Cervical cancer (CC) screening and prevention are crucial responsibilities of obstetrician-gynecologists (OB/GYNs). Our study aimed to investigate whether knowledge impacts OB/GYNs' (n = 42) adherence to CC prevention measures by comparing them to non-OB/GYN physicians (n = 80). An anonymous questionnaire collected demographic information, personal screening habits and evaluated their knowledge of CC prevention. Results revealed that OB/GYNs exhibited superior knowledge of CC risk factors and prevention compared to non-OB/GYNs. Of note, a lower percentage of OB/GYN residents correctly identified the recommended upper age limit for cervical screening and for HPV vaccination compared to attending OB/GYNs (50% vs. 83%, p = 0.04 and 11% vs. 50%, p = 0.01, respectively). Despite these findings, most physicians from both groups recommended HPV vaccination. Cervical screening rates were similar between OB/GYNs and non-OB/GYNs (75% vs. 83%, p = 0.3). Half of OB/GYNs initiated their own cervical screening, similar to non-OB/GYNs. Interestingly, residents had higher HPV vaccination rates compared to attending physicians, irrespective of specialty (OB/GYNs - 38.89% vs. 4.76%, p = 0.0149; non-OB/GYNs - 51.06% vs. 15.38%, p = 0.0028). In conclusion, contrary to the assumption that physicians prioritize personal well-being, our study reveals the opposite. While skilled in guiding patients through CC screening and prevention, female OB/GYNs often neglect their own health. OB/GYNs must also be educated and supported in safeguarding their health, setting an essential example for patients.

Abstract
OBJECTIVE To determine fetal gender on umbilical cord parameters. METHODS Umbilical cords were prospectively collected from uncomplicated, singleton, term pregnancies, which ended either by elective cesarean section or spontaneous vaginal delivery. Data regarding obstetrical history and pregnancy outcome were collected. Various cord parameters were examined including, length, number of coils, umbilical cord index (UCI), which demonstrate the ratio between number of coils and cord length, site of placental insertion, direction of coiling and the presence of true knots. RESULTS Overall, 154 umbilical cords were collected, of them 84 from male and 70 from female newborns. No differences were found regarding obstetrical history parameters or pregnancy outcome between the groups. The umbilical coiling index was significantly higher in female compared to male newborns (0.183 coils/cm versus 0.157 coils/cm, p=.006) due to higher number of cord coils (12.25 ± 5.31 vs. 10.17 ± 3.96, p=.007), with no difference in cord length (66.48 vs. 64.61 cm, p=.372). These differences remained statistically significant even after correction for gravidity, parity and gestational age using multiple linear regression analysis. CONCLUSION Female newborns having higher umbilical cord index, compared to male as a result of more coils, with no length dissimilarity.

Abstract
OBJECTIVE The pathological picture in ischemic tissue injury shares features with the inflammatory response. Hypoxia-mediated induction of interleukin-6 (IL-6) could set in motion the mechanisms limiting inflammation in ischemia. Intrauterine growth restriction (IUGR) represents a human model of chronic fetal hypoxia. The purpose of this study was a first-time exploration to determine whether cord blood obtained at the delivery of small-for-gestational-age (SGA) infants has increased concentrations of inflammatory markers. STUDY DESIGN Cord blood was collected from 20 SGA (term and near-term) infants and 20 appropriate-for-gestational-age (AGA) controls. Infants exposed to maternal smoking, diabetes, maternal chronic diseases, or alcohol or drug use were excluded. Both groups had Apgar score ≥7 at 1 min with a normal cord pH (>7.25). Cord-serum cytokines and thrombopoietin (TPO) levels were measured by enzyme linked immunosorbent assay. C-reactive protein (CRP) was measured using a turbidometric immunoassay. RESULT SGA infants had a significantly smaller birth weight than AGA controls, with a smaller gestation age by 1 week. There were significant elevations in IL-6, tumor necrosis factor (TNF-α), CRP and TPO in the SGA compared with the AGA group, which persisted in multiple regression analysis even after gestational age was taken into account. CONCLUSION As hypothesized, significant increases in the cord blood concentrations of known inflammatory markers were found in SGA infants compared with the controls.

Abstract
BACKGROUND Little is known about the glucose concentrations at and after birth of infants delivered by caesarean section (CS), when compared with infants born vaginally (VD). AIM To compare venous cord blood glucose concentrations of term infants born after elective CS to infants born by VD. We studied the null hypothesis that mode of delivery does not affect neonatal blood glucose values. METHODS We compared cord blood glucose concentrations in healthy term infants born after VD (n = 16) or by elective CS (n = 21). Glucose concentrations were obtained immediately at birth from the umbilical cord. Kruskal-Wallis was used to compare glucose concentrations and demographic variables between the groups. RESULTS Gestational age was 39.6 ± 0.8 weeks in VD group vs. 38.7 ± 0.9 weeks in CS group, and birthweight was 3359 ± 494 vs. 3500 ± 528 g. Cord blood glucose concentration was higher in VD (81.3 ± 16.9 mg/dL) than CS infants (70.3 ± 9.7 mg/dL, p = 0.039). The change in blood glucose concentration over the first 2-h of life differed significantly between the two groups, being an increase in CS versus a decrease in VD infants (-3.5 ± 15.2 vs. -15.4 ± 24.6 mg/dL, p = 0.013). CONCLUSIONS Glucose concentrations in VD infants are higher than in infants born by elective CS without labour.

Abstract
OBJECTIVE Prohepcidin (Pro-Hep), synthesized in the liver, is the prohormone of hepcidin (Hep), which reduces iron absorption in the gut; its synthesis is enhanced by inflammation and is reduced during hypoxia. We aimed to study the hypothesis that infants born small for gestational age (SGA) have reduced cord blood concentrations of Pro-Hep. STUDY DESIGN Cord blood was collected from 20 SGA (term and near term >35 week gestation) infants and 20 appropriate for gestational age (AGA) controls. We excluded infants exposed to maternal chronic diseases, smoking, diabetes, alcohol or drug use. Both groups had a 1 min Apgar score above or equal to 7 and had normal cord blood pH (above 7.25). ELISA was used to determine serum concentrations of Pro-Hep and erythropoietin (EPO). Circulating CD71(+)/CD45(-)/SSC(low) cells were measured by flow cytometry as an index of erythroid progenitors. RESULT There were no significant differences between groups in terms of hemoglobin concentrations, and Pro-Hep. In contrast, EPO levels and circulating CD71(+)/CD45(-)/SSC(low) erythroid progenitors were significantly higher in the SGA group. These differences remained significant even after controlling for gestational age and gravidity. CONCLUSION Contrary to EPO upregulation during intrauterine growth restriction (IUGR), and higher concentrations of circulating erythroid progenitors, Pro-Hep concentration is not affected by IUGR.

Abstract
OBJECTIVE To compare selected umbilical cord parameters, especially cord coiling, between breech and vertex presentations. METHODS We prospectively collected umbilical cords from uncomplicated breech and vertex obtained during elective term cesarean deliveries. We compared various cord parameters between the two groups as well as data regarding obstetric history and pregnancy outcome. RESULTS We evaluated 55 umbilical cords from breech and 55 from vertex deliveries. Umbilical cord length (56.93 cm vs. 63.95 cm, P=0.05), number of coils (5.1+/-0.4 vs. 11.7+/-0.6, P<0.0001) and umbilical cord index (UCI) (0.09 coils/cm vs. 0.18 coils/cm, P<0.0001) were all significantly lower for breech presentations and remained significant following multivariate analysis. CONCLUSION We document significant differences in umbilical coiling and the UCI between breech and vertex presentation. The precise reason for these differences is still unclear.

Abstract
BACKGROUND The pathologic features of Down syndrome are assumed to be the result of over-expression of genes located on chromosome 21 and/or a more global transcriptional misregulation that crosses chromosomal borders. METHODS To address this issue, four RNA samples from trisomy 21 placentas and four samples from normal first trimester pregnancies were analyzed using Affymetrix U95v2 microarray. Statistical and bioinformatic analyses were employed to compare global gene expression, functional classes, and pathways to differentiate between placentas taken from trisomy 21 and from normal pregnancies. RESULTS About 750 genes were significantly over-expressed in trisomy 21. This list contains an approximately 4.5-fold over-abundance of genes that map to chromosome 21, compared to that which could be expected for this chromosome, on the microarray. Among the classes of genes that best discriminated the trisomy 21 and normal karyotype, we found genes that are also implicated in Alzheimer disease and genes that are associated with ubiquitination and proteosomal degradation. Finally, using the top 10 most discriminating genes, eight samples taken from a different database were correctly classified as either trisomy 21 or normal. CONCLUSIONS Our results demonstrate that gene expression in trisomy 21 affected placentas significantly differs from that of chromosomally normal placentas, and this difference is only partially explained by over-expression of genes from chromosome 21. Our findings suggest that specific highly discriminatory genes may be potential targets for further research and development of novel prenatal diagnosis techniques.

Abstract
OBJECTIVE Isolated nonvisualized fetal gallbladder (INVFGB) is relatively rare. In most cases, the gallbladder will eventually be detected. In some cases however, INVFGB may be associated with serious abnormalities, cystic fibrosis (CF), aneuploidy, and agenesis of the gall bladder. We describe a clinical evaluation of prenatally diagnosed INVFGB. METHODS Cases of nonvisualized gallbladder were first evaluated by serial scans. Cases with no additional malformations were designated as INVFGB, and were further evaluated by mutation analysis for CF, and amniocentesis for karyotype and microvillar membrane enzymes (MME). RESULTS A total of 22 cases of nonvisualized gallbladder were detected. Of these, 2 had additional malformations, and 3 were excluded because of incomplete evaluation. Of the remaining 17 cases, 3 (17.6%) had adverse outcomes: 1 case of CF, 1 case of 47,XXX, and 1 case of multiple congenital anomalies detected only postnatally. Abnormal levels of MMEs were detected in 3 cases, 1 of which was diagnosed with CF. In 2 cases, the gallbladder was not detected even after birth, but development is normal. CONCLUSION Evaluation of INVFGB should include genetic counselling, amniocentesis for karyotype and MME analysis, CFTR mutation analysis and repeated ultrasound scans.

Abstract
OBJECTIVE Quantitative fluorescence polymerase chain reaction (QF-PCR) is a rapid method for detection of chromosome copy number by amplification of repeat sequences at polymorphic loci. Our objective was to assess the performance of QF-PCR in detecting common aneuploidies in prenatal diagnosis. STUDY DESIGN The study group consisted of pregnant women referred for amniocentesis or chorionic villus sampling (CVS) due to increased risk of fetal aneuploidy. Samples were collected from known affected and normal pregnancies. These were blindly screened for trisomy of chromosomes 21, 18, 13, and sex chromosome abnormalities, using QF-PCR. DNA from uncultured amniocytes was directly extracted using a modified alkaline lysis method. DNA from CVS was extracted by the phenol-chloroform procedure. Ten short tandem repeat (STR) markers were used for detection of fetal aneuploidy and gender. The STRs were selected for high heterozygosity rates and efficiency of the PCR amplification. The forward primer of each pair was labeled with a unique fluorescent dye. Amplified products were detected by an ABI Prism 310 Genetic Analyzer and results were analyzed using GeneScan Analysis Software. RESULTS A total of 65 amniotic fluid and CVS samples were collected from affected and normal pregnancies. Two samples were contaminated with blood and were therefore excluded from the analysis. All 29 cases of aneuploidy were correctly diagnosed by QF-PCR, including 17 cases of trisomy 21, 7 cases of trisomy 18, and 5 cases with trisomy 13. The 34 normal samples were also correctly diagnosed as such. Thus, all results were in agreement with the standard cytogenetic results. There were no false-positive or false-negative results. CONCLUSION We conclude that QF-PCR is a rapid, reliable, and reproducible method that may be used to provide rapid results in prenatal diagnosis of aneuploidy.

Abstract
PURPOSE The aim of the study was to evaluate the contribution of gray-scale sonography and Doppler flow studies in differentiating between uterine sarcomas of different histologic types and leiomyomas. PATIENTS AND METHODS The study included 111 patients, divided retrospectively into 2 groups: 98 patients with leiomyomas and 13 with postoperative diagnosis of uterine sarcoma. This latter group was further divided into a group of 6 patients with uterine leiomyosarcoma and 7 with malignant mixed mesodermal tumor. The gray-scale sonograms and Doppler parameters in the 3 groups were compared. RESULTS The patients with leiomyomas were younger than those with sarcomas (52 years +/- 11 versus 65 years +/- 15, p < 0.05). No differences were noted between the 3 groups regarding gravidity, parity, symptoms upon admission, or findings during physical examination. The sonographic appearances of the leiomyomas were similar to those of the leiomyosarcomas, but in 6/7 cases, they were different from those of the malignant mixed mesodermal tumors. There was a significant difference between the mean resistance index in arterioles of the leiomyomas (0.59 +/- 0.01) and that of the malignant mixed mesodermal tumors (0.41 +/- 0.06) (P < 0.001) but not between those of the leiomyomas and the leiomyosarcomas (0.49 +/- 0.18). CONCLUSIONS Doppler flow studies may assist in differentiating between leiomyomas and malignant mixed mesodermal tumors but not between leiomyomas and leiomyosarcomas.

Abstract
OBJECTIVE To evaluate the levels of first-trimester screening markers in triploid pregnancies and to determine the parental origin of triploidy. STUDY DESIGN During the five-year study period, 12322 patients with singleton pregnancies underwent combined first-trimester screening using nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotrophin (free beta-hCG) and pregnancy associated plasma protein-A (PAPP-A) at 10 to 14 weeks' gestation. Maternal serum markers and NT were evaluated in cases of triploidy. Molecular analysis was performed using polymorphic markers to establish the parental source of triploidy. RESULTS Eight cases of triploidy were detected at a rate of at least 1 in 1540. All cases were electively terminated early in gestation or resulted in spontaneous miscarriage. Two patterns of first-trimester markers emerged: type I, characterized by extremely high levels of free beta-hCG and elevated NT; and type II, characterized by very low levels of PAPP-A and free beta-hCG with normal NT. Molecular analysis demonstrated that type I triploidy is of paternal origin (diandric) and type II is of maternal origin (digynic). CONCLUSIONS On the basis of these results, it may be possible to detect triploid pregnancies in the first trimester and determine their origin using combined first-trimester screening.

Abstract
OBJECTIVE The prenatal detection of de novo extra structurally abnormal chromosomes (ESACs) presents a challenge because the associated risk for congenital anomaly ranges from 100% to practically none, depending on the chromosomal origin. Despite the use of standard cytogenetic techniques and even fluorescence in situ hybridization (FISH), the origin of some ESACs often remains elusive. Spectral karyotyping (SKY) is a molecular cytogenetic technique based on the simultaneous analysis of all chromosomes using a unique probe mix that allows the rapid identification of all chromosomes in 24 colors. The purpose of this study was to evaluate the use of SKY in the characterization of prenatally diagnosed de novo ESACs. METHODS This series includes five cases of de novo ESACs detected prenatally in routine amniocentesis samples performed for advanced maternal age. Cases of inherited ESACs or ESACs defined by standard cytogenetic techniques were excluded. RESULTS SKY analysis yielded valuable information, particularly in cases of nonsatellited ESACs: a der(18) and a ring(Y). In a case of a unisatellited der(15), SKY corroborated data obtained by standard cytogenetic techniques and FISH. Finally, in two cases of small bisatellited chromosomes, SKY was noncontributory. CONCLUSIONS While SKY may be a valuable tool in some cases, especially nonsatellited and ring ESACs, it does have limitations and should be used judiciously in conjunction with other cytogenetic techniques.

Abstract
OBJECTIVE The purpose of this study was to evaluate whether abnormal levels of first trimester maternal serum free human chorionic gonadotropin (beta-hCG) are predictive of adverse pregnancy outcomes. METHODS The study included 1,622 consecutive patients with singleton pregnancies who underwent first trimester Down syndrome screening using nuchal translucency, and maternal serum free beta-hCG and pregnancy-associated plasma protein-A. Patients with fetal anomalies or chromosome aberrations were excluded from the study. The incidences of various adverse pregnancy outcomes were evaluated according to maternal serum free beta-hCG levels. Outcome variables included spontaneous miscarriage, proteinuric and non-proteinuric pregnancy-induced hypertension, fetal growth restriction, intrauterine fetal demise, spontaneous preterm delivery, oligohydramnios and placental abruption. RESULTS No significant differences were noted between groups for any of the demographic variables. The only statistically significant result was an increase in the relative risk for spontaneous miscarriage (RR = 6.33) at free beta-hCG <0.2 multiples of the medians. No other statistically significant result was noted for the other adverse outcomes or for the overall complication rate. CONCLUSION Low free beta-hCG is associated with a higher incidence of spontaneous miscarriage but is a poor predictor of other pregnancy complications.

Abstract
OBJECTIVE Low levels of maternal serum pregnancy associated plasma protein-A (PAPP-A) have been linked to chromosome anomalies such as trisomy 21, 13 and 18, triploidy and sex chromosome aneuploidy. Low levels of PAPP-A have also been implicated in spontaneous miscarriage. The purpose of this study was to evaluate whether low levels of first trimester PAPP-A are predictive of other adverse pregnancy outcomes. STUDY DESIGN The study included patients with singleton pregnancies who underwent combined first trimester screening using nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotrophin (free beta-hCG) and PAPP-A at 10-13 weeks' gestation. Patients with chromosome aberrations or fetal anomalies were excluded. Serum marker levels were expressed as gestational age-specific multiples of the median (MoMs). The incidences of various adverse pregnancy outcomes (spontaneous preterm labor, fetal growth restriction (FGR), proteinuric and non-proteinuric pregnancy induced hypertension (PIH), intrauterine fetal demise, oligohydramnios, spontaneous miscarriage and placental abruption) were evaluated, according to maternal PAPP-A MoM levels. RESULTS Of the 1622 patients in the study, pregnancy complications were observed in 184 (11.3%). Patients with PAPP-A < or =0.25 MoM had significantly higher rates of FGR (RR = 3.12), proteinuric PIH (RR = 6.09), spontaneous miscarriage (RR = 8.76). No statistically significant differences were noted for other adverse outcomes evaluated Women with PAPP-A < or =0.50 MoM also had significantly higher rates of FGR (RR = 3.30) and spontaneous miscarriage (RR = 3.78). CONCLUSIONS We conclude that decreased levels of first trimester maternal serum PAPP-A are predictive not only of chromosome anomalies but also of adverse pregnancy outcome.

Abstract
OBJECTIVES The purpose of the present study was to evaluate whether a gender-related difference exists in first trimester markers used for Down syndrome screening, namely nuchal translucency (NT), maternal serum pregnancy-associated plasma protein-A (PAPP-A), and free beta-human chorionic gonadotrophin (beta-hCG), and whether this has an influence on screening performance. METHODS A total of 1325 patients with a singleton pregnancy underwent combined first trimester screening at 10-13 weeks' gestation. Maternal serum PAPP-A and free beta-hCG were analyzed by fluoroimmunoassay, nuchal translucency (NT) was measured by transvaginal sonography. Only patients with normal outcomes and known fetal gender were included in the study. Data were categorized by gestational age and by fetal gender. RESULTS There were no significant gender-related differences in NT and PAPP-A levels. However, free beta-hCG was significantly higher (p=0.00004) in the presence of a female fetus than in the presence of a male fetus. Women with female fetuses had a higher median calculated Down syndrome risk (1:5490) compared to those having males (1:6451). This difference was not, however, statistically significant. CONCLUSION First trimester free beta-hCG is significantly higher in pregnancies with a female fetus.

Abstract
Obstetric complications, such as severe pre-eclampsia, fetal growth restriction, abruptio placentae, or stillbirth are associated with abnormally elevated second-trimester maternal serum alpha-fetoprotein (MSAFP) and beta subunit of human chorionic gonadotrophin (betahCG). This has been attributed to placental abnormalities. Women with thrombophilias have been shown to have abnormalities of the placenta resulting in adverse pregnancy outcome in these patients. The purpose of the present study was to evaluate whether women with pregnancy complications and inherited thrombophilias have abnormally elevated second-trimester MSAFP or betahCG. Sixty-two women with pregnancy complications were tested for inherited thrombophilias several months after delivery. The thrombophilia group included 29 women with pregnancy complications and an inherited thrombophilia and the control group included 33 other patients without thrombophilia. Patients in the thrombophilia group had a higher median MoM MSAFP compared to the controls (1.337 vs. 1.086, p=0.0516). The incidence of abnormally elevated MSAFP (>2.5 MoM) was also significantly higher in the thrombophilia group compared to controls (21% vs. 3%, p=0.04). Neither the median MoM betahCG nor the incidence of abnormally elevated betahCG were significantly different between the groups. We conclude that second trimester MSAFP, but not betahCG, is abnormally elevated in patients with thrombophilia and obstetric complications.

Abstract
Combined first trimester screening using pregnancy associated plasma protein-A (PAPP-A), free beta-human chorionic gonadotrophin, and nuchal translucency (NT), is currently accepted as probably the best combination for the detection of Down syndrome (DS). Current first trimester algorithms provide computed risks only for DS. However, low PAPP-A is also associated with other chromosome anomalies such as trisomy 13, 18, and sex chromosome aneuploidy. Thus, using currently available algorithms, some chromosome anomalies may not be detected. The purpose of the present study was to establish a low-end cut-off value for PAPP-A that would increase the detection rates for non-DS chromosome anomalies. The study included 1408 patients who underwent combined first trimester screening. To determine a low-end cut-off value for PAPP-A, a Receiver-Operator Characteristic (ROC) curve analysis was performed. In the entire study group there were 18 cases of chromosome anomalies (trisomy 21, 13, 18, sex chromosome anomalies), 14 of which were among screen-positive patients, a detection rate of 77.7% for all chromosome anomalies (95% CI: 55.7-99.7%). ROC curve analysis detected a statistically significant cut-off for PAPP-A at 0.25 MoM. If the definition of screen-positive were to also include patients with PAPP-A<0.25 MoM, the detection rate would increase to 88.8% for all chromosome anomalies (95% CI: 71.6-106%). This low cut-off value may be used until specific algorithms are implemented for non-Down syndrome aneuploidy.

Abstract
OBJECTIVE To evaluate pregnancy outcome of assisted reproductive technology (ART)-conceived twin pregnancies. DESIGN Retrospective study. SETTING A tertiary obstetric care center. PATIENT(S) All twin pregnancies delivered > or = 24 weeks of gestation from January 1, 1996, to December 31, 1997. INTERVENTION(S) Maternal and neonatal record review. MAIN OUTCOME MEASURE(S) Pregnancy and perinatal outcome. RESULT(S) The study group comprised 104 ART-conceived twin pregnancies, and 193 non-ART-conceived pregnancies served as controls. Mean maternal age, the proportion of nulliparae, and the percentage of women who delivered before 34 weeks' gestation was higher among the study women, whereas mean gestational age was younger. The incidences of pregnancy-induced hypertension, uterine bleeding, premature contractions, intrauterine growth retardation, fetal death, discordance, and cesarean section were significantly higher in the study group. Correspondingly, in the study group, the mean birth weight of both twins was lower; more neonates weighed < 1, 500 g, more had Apgar scores of < 7 at 5 minutes, more were admitted to the intensive care unit, and more second twin neonates died. The outcome of twin pregnancies conceived spontaneously was comparable with those conceived by ovulation induction. CONCLUSION(S) Assisted reproductive technology-conceived twin pregnancies are at greater risk than non-ART-conceived ones for pregnancy complications and adverse perinatal outcome.

Abstract
Rectal carcinoma is rare during pregnancy. Prognosis is usually unfavorable due to late diagnosis, and management, especially regarding the mode of delivery, is controversial. Current treatment of rectal carcinoma includes neoadjuvant chemoradiotherapy, which may influence obstetrical management. We present a case report and discuss obstetrical management in view of updated knowledge and therapeutic approaches.

Abstract
There are numerous studies concerning pregnancy rates in oocyte donation, yet only a handful report the obstetric outcome in such pregnancies. The purpose of this study was to assess factors that influence pregnancy rates, to determine the incidence of complications, and to evaluate obstetric outcome in pregnancies resulting from oocyte donation. This study included 423 oocyte recipients who underwent 1001 oocyte donation cycles at the Oocyte Donation Programme, In-Vitro Fertilization (IVF)-Embryo Transfer Unit, Herzlia Medical Center, Israel. Donors were all healthy women < 34 years old who underwent IVF themselves. In 873 cycles, fertilization occurred and embryo transfer was performed, resulting in 194 clinical pregnancies. Pregnancy rates (PR) significantly declined with the increase in number of previous attempts, and with increasing age of recipient (36.8%/embryo transfer in patients < or = 30 compared to 17.8% in patients > 40 years old). A significant increment in PR was noted with the increasing number of embryos transferred. The overall PR was 22.2%/embryo transfer. However, in young amenorrhoeic patients with normal karyotypes undergoing their first cycle, PR was 52.2%; the 'take home baby' rate was 38.3% per patient undergoing embryo transfer and 17.8% per embryo transfer cycle. A significant increase in the incidence of pregnancy-induced hypertension and a higher proportion of abortions were noted in older patients. A significantly higher incidence of prematurity and low birthweight was observed in multiple pregnancies.

Abstract
OBJECTIVE To evaluate whether endometrial receptivity is compromised in patients with premature ovarian failure (POF) due to Turner's syndrome who undergo oocyte donation. DESIGN Retrospective analysis. SETTING In vitro fertilization-ET units, anonymous oocyte donation program. PATIENTS The study included 53 patients with POF who underwent oocyte donation. These included 7 patients with Turner's syndrome (45,X) who underwent 22 ET cycles, 15 women with Turner variants (mosaics, deletions, or isochromosomes) who underwent 36 ET cycles, and 31 other patients with POF and a normal karyotype who underwent 69 oocyte donation cycles. INTERVENTION All patients on standby for donation were treated with E2 valerate 6 mg/d until oocytes became available; then P 100 mg/d was added. Oocyte donors were healthy women < 34 years who underwent IVF themselves. MAIN OUTCOME MEASURES Clinical pregnancy rates (PRs), biochemical pregnancies, early abortions, and delivery rates were evaluated. RESULTS Turner's syndrome patients had a significantly higher rate of biochemical pregnancies (22.7% versus 4.3%), a lower clinical PR (22.7% versus 33.3%), a significantly higher rate of early abortions (60% versus 8.7%), and a significantly lower rate of deliveries per pregnancy (20.0% versus 73.1%) compared with non-Turner patients. CONCLUSIONS Patients with a complete or partial deficiency of an X chromosome have reduced PRs and an increase in early implantation failure after oocyte donation. This may indicate an inherent endometrial abnormality, possibly associated with a deficiency of X-linked genes regulating endometrial receptivity.
