Abstract
RESEARCH QUESTION Is there an association between intrauterine hematoma (IUH), vanishing twin syndrome (VTS), and subsequent complications in twin pregnancies after in vitro fertilization (IVF)? What are the risk factors for these complications? DESIGN Women who presented with two live gestational sacs following double embryo transfer were included. Patients with systematic diseases, artificial fetal reduction, and incomplete data were excluded. Further stratification of IUH pregnancies was performed according to IUH-related characteristics (i.e., volume, changing pattern, and relationship with fetal cardiac activities). The primary outcome was the incidence of VTS, while adverse outcomes in the surviving singleton and the gestational age of VTS were secondary outcomes. RESULTS The incidence of IUH was 13.8%. A total of 1,078 twin pregnancies including 539 IUH pregnancies and 539 non-IUH pregnancies were included. IUH pregnancy was associated with higher risks of VTS (26.9% vs. 18.7%, p = 0.001) as well as a higher incidence of preterm birth (p = 0.001, crude OR = 1.98, 95% CI 1.28-3.09, adjusted OR = 1.19, 95% CI 1.09-1.24), threatened abortion (p < 0.001, crude OR = 9.12, 95% CI 2.90-28.69, adjusted OR = 6.63, 95% CI 1.69-14.67), and postpartum hemorrhage (p = 0.024, crude OR = 3.13, 95% CI 1.09-8.99, adjusted OR = 1.16, 95% CI 1.08-1.32) in the surviving singleton. There was no significant difference in risks of other complications. The absence of fetal cardiac activities at the diagnosis of IUH predicted VTS (p < 0.001, crude OR 4.67, 95% CI 3.67-5.78, adjusted OR 3.33, 95% CI 1.56-5.14) and fetal loss at smaller gestational age (7.81 ± 2.10 vs. 11.39 ± 5.60 weeks, p < 0.001), while an IUH with an increasing volume did not increase the risk of VTS but might induce threatened abortion in the surviving fetus (p < 0.001, crude OR 1.84, 95% CI 1.32-2.55, adjusted OR 1.72, 95% CI 1.13-2.13). CONCLUSIONS IUH was a risk factor for VTS in twin pregnancies following double embryo transfer and elevated the risks of threatened abortion, preterm birth, and postpartum hemorrhage in the surviving singleton. The absence of fetal cardiac activities at the diagnosis of IUH elevated the risks of VTS, while an IUH with an increasing volume was associated with threatened abortion without elevating the risks of VTS. An IUH diagnosed before the presence of fetal cardiac activities also resulted in an earlier miscarriage. The study suggests that attention be paid to twin pregnancies with first-trimester IUH to prevent VTS and subsequent adverse perinatal outcomes. HIGHLIGHTS First-trimester intrauterine hematoma (IUH) following double embryo transfer is associated with a higher incidence of vanishing twin syndrome (VTS) and elevated subsequent risk of threatened abortion, preterm birth, and postpartum hemorrhage in the surviving singleton. Other perinatal outcomes were not associated with the diagnosis of first-trimester IUH. The absence of fetal cardiac activities at the diagnosis of IUH was of predictive value toward VTS, while an IUH with an increasing size was associated with threatened abortion without elevating the risk of VTS. Incomplete fetal cardiac activities and earlier detection of an IUH might also predict miscarriage at smaller gestational age.

Vishnevsky G, Shoham Z, Or Y. Is there a pre-retrieval serum human chorionic gonadotrophin (hCG) threshold level for prediction of subsequent retrieval outcomes and pregnancy in fresh ICSI cycles? Gynecol Endocrinol 2020; 36:641-645. [PMID: 31847630 DOI: 10.1080/09513590.2019.1699049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/25/2022] Open
Abstract
Modern ICSI (intracytoplasmic sperm injection) cycles' outcomes are difficult to predict. Whether human chorionic gonadotrophin (hCG) or luteinizing hormone (LH) serum levels 24 h prior to oocyte retrieval are correlated with retrieval and subsequent cycle results is unclear. An observational historic cohort study of 645 fresh ICSI cycles was conducted. After controlled oocyte stimulation, and 10-12 h after a self-administered trigger, serum levels of hCG (hCG trigger n = 563) and LH (GnRHa trigger n = 82) were measured. Correlations between pre-retrieval hormone levels and cycle results were assessed. No correlation (p > .12) was found between serum pre-retrieval hCG levels or LH levels (in GnRHa-triggered cycles) and total oocytes, M2, M1 + M2 or oocyte maturity rates (OMR) for any of the stimulation protocols. ROC (receiver operator curve) analysis for fertilization rates showed a possible cutoff for LH levels. Pregnancy rates (PR) were higher in rising hCG groups; a cutoff of 117 IU/L was associated with an increase in PR (30.9% to 45.6%) and a moderate sensitivity and specificity (60.6% and 55.0%). However, HCG was not predictive of pregnancy in a logistic regression model. We conclude that preretrieval hCG serum levels are not useful for pre-retrieval estimation of aspiration results but might have a role in prediction of pregnancy.

Abstract
The aim of this study was to investigate the factors predicting clinical pregnancy rate of in vitro fertilization-embryo transfer (IVF-ET).The data of 9960 patients receiving IVF-ET fresh cycle at our Reproductive Center from January 2009 to December 2017 were first divided into pregnant group and non-pregnant group to find the clinical pregnancy rate-related factors. According to the serum HCG levels at 36 hours and 12 hours after HCG trigger, all patients were divided into 4 groups including <50 mIU/ml, ≥50 and <100 mIU/ml, ≥100 and <200 mIU/ml, and ≥200 mIU/ml groups to know whether the HCG levels at 36 hours and 12 hours affect the pregnancy rate. According to the serum HCG ratio at 36 hours to 12 hours (36 h/12 h) after HCG trigger, all patients were divided into three groups including <0.88, 0.88-1.06 and >1.06 groups to observe whether the serum HCG ratio (36 h/12 h) affects the clinical pregnancy rate. According to different assisted pregnancy modes, all patients were divided into 3 groups including IVF, ICSI, and IVF/ICSI groups to observe whether the assisted pregnancy mode affects the clinical pregnancy rate. The correlation of the clinical pregnancy rate with pregnancy rate-related factors obtained above was analyzed using logistic regression analysis model.The clinical pregnancy rate significantly increased (P < .01) in the HCG ratio (36 h/12 h) >1.06 group as compared with the HCG ratio (36 h/12 h) < 0.88 and 0.88-1.06 groups. The serum estrogen (E2) level at 36 hours was significantly lower and the number of retrieved oocytes was significantly higher in the HCG ratio (36 h/12 h) >1.06 group than in the HCG ratio (36 h/12 h) <0.88 and 0.88-1.06 groups (P = .000).The serum HCG ratio (36 h/12 h) may be used as a predictor of IVF-ET clinical pregnancy rate. High clinical pregnancy rate is probably associated with E2 down-regulation in the HCG ratio (36 h/12 h) >1.06 group.

Human chorionic gonadotropin serum levels following ovulation triggering and IVF cycle outcome. J Assist Reprod Genet 2018; 35:891-897.

Abstract
PURPOSE The clinical significance of serum hCG levels after ovulation triggering was studied previously with conflicting results. Our aim was to study the correlation of hCG levels on the day after ovulation triggering using recombinant hCG (r-hCG) with treatment outcome. METHODS A prospective observational study of all fresh IVF/ICSI cycles in a single medical center, between January 2015 and June 2016, was performed. hCG serum levels were obtained 10-12 h following ovulation triggering with 250 mcg r-hCG. Clinical and laboratory outcome parameters were compared between cycles with serum hCG above and below median level. A multivariate regression analysis was performed in order to study the association between hCG levels and live birth rate, after controlling for confounders. RESULTS Overall, 326 cycles were included. Median serum hCG level was 91.35 IU/L. hCG levels were lower as age and BMI were higher (p = 0.004, p < 0.001, respectively). The study groups did not differ with regard to clinical pregnancy rate (p = 0.14), live birth rate (p = 0.09), fertilization rate (p = 0.45), or metaphase II oocyte rate (p = 0.68). On multivariate regression analysis, hCG level was not associated with live birth (aOR 0.99, 95% CI 0.98-1.005), after controlling for patient's age and BMI. CONCLUSIONS hCG levels on the day after ovulation triggering with 250 mcg r-hCG are inversely correlated with patient age and BMI. However, they are not correlated with any clinical or laboratory outcome parameter. Therefore, testing for hCG levels after ovulation induction seems futile and cannot be recommended.

Abstract
PURPOSE To study the association between the numbers of oocytes retrieved and the cumulative live birth rates (LBR) in women aged 35-40 years undergoing long GnRH agonist IVF/ICSI cycles. METHODS A total of 931 women aged 35-40 years who underwent their first cycle of IVF/ICSI treatment between January 2010 and December 2013 at Nanjing Drum Tower Hospital were identified and reviewed. The main endpoint of this study was the cumulative LBR after one complete oocyte retrieval, which included fresh and all subsequent frozen-thaw embryo transfer cycles. Odds ratios (OR) and 95% confidence interval (CI) for live birth were estimated by multivariate logistic regression analysis. Furthermore, all the women were divided into four groups based on the number of oocytes retrieved: 0-4, 5-9, 10-14 or ≥15 oocytes group. Variables were then compared among groups. RESULTS We found that 634 out of the 931 patients (68.1%) achieved at least one live birth. The number of oocytes retrieved was an independent predictive factor for live birth, with OR 1.20 (95% CI 1.15-1.26) when adjusted for age (years), duration of infertility and Gn (gonadotrophin) doses. The cumulative LBR in the four different oocyte groups was 35.6, 68.8, 83.4 and 89.2%, respectively. When the 1-4 oocytes group was issued as a reference, the ORs for cumulative LBR gradually increased to 3.66, 6.74 and 11.77 in other three oocytes groups, respectively. The moderate-severe ovarian hyperstimulation syndrome (OHSS) rate was dramatically increased in the ≥15 oocytes group (6.9%) when compared to that in the 10-14 oocytes group (0.8%), while the cumulative LBR only increased 5.8% (from 83.4 to 89.2%). CONCLUSIONS The ideal number of oocytes retrieved in women aged 35-40 years is 10-14 oocytes, which achieves a high cumulative LBR while maintaining an acceptable low OHSS rate.

Abstract
OBJECTIVE The aim of this retrospective cohort study was to assess the effect of subchorionic hematoma (SCH) on pregnancy outcomes in IVF/ICSI patients. METHODS We retrospectively analyzed 1097 pregnancies achieved by in vitro fertilization and embryo transfer (IVF-ET) or frozen-thawed embryo transfers (FETs) between January 2013 and June 2013 at the IVF center of Nanjing Drum Tower Hospital. The prevalence of SCH was 12.1% in this group (133/1097). We compared the pregnancy outcomes between the SCH group and non-SCH group, while the risk factors for SCH were also evaluated. RESULTS There was no significant difference between SCH group and non-SCH group with regard to patients' age, spouse's age, endometrial thickness, miscarriage rate (5.6% versus 6.2%, p > 0.05), second trimester fetus loss rate (5.6% versus 7.7%, p > 0.05) or live birth rate (89.5% versus 86.1%, p > 0.05). While the birth weight in singleton pregnancy in SCH group was significant lower (3207.8 ± 595.7 g versus 3349.2 ± 59.7 g, p = 0.03). SCH was more common in fresh embryo transfer patients than that in FET patients (16.6% versus 5.1%, p < 0.01), fresh embryo transfer was a high risk for SCH with OR 3.67, 95% CI: 2.28-5.90. CONCLUSION We concluded that SCH was associated with lower birth weight in singleton pregnancy, but SCH did not increase pregnancy loss rate in IVF/ICSI patients, and fresh embryo transfer may contribute to SCH onset.
