This study aimed to investigate the associations between the post-wash total progressively motile sperm count (TPMSC) in the first intrauterine insemination (IUI) cycle and pregnancy outcomes of the second IUI cycle. Data were retrieved from the clinical database at the Reproductive Center of Peking University Third Hospital (Beijing, China) between January 2011 and December 2022. Couples were included in this retrospective cohort study if they had unexplained or mild male factor infertility and were treated with IUI for two consecutive cycles using the same protocol. A total of 8290 couples were included in the analysis. The mean ± standard deviation (s.d.) age of women was 32.0 ± 3.5 years. We categorized groups based on the post-wash TPMSC (×10 6 ) levels in the first IUI cycle: group 1 (0 < TPMSC < 1, n = 1290), group 2 (1 ≤ TPMSC < 2, n = 863), group 3 (2 ≤ TPMSC < 3, n = 800), group 4 (3 ≤ TPMSC < 4, n = 783), group 5 (4 ≤ TPMSC < 5, n = 1541), group 6 (5 ≤ TPMSC < 6, n = 522), group 7 (6 ≤ TPMSC < 7, n = 547), group 8 (7 ≤ TPMSC < 8, n = 175), group 9 (8 ≤ TPMSC < 9, n = 556), group 10 (9 ≤ TPMSC < 10, n = 192), and group 11 (TPMSC ≥ 10), n = 1021). The primary outcome was live birth rate of the second IUI cycle. Live birth rates were 7.9%, 5.8%, 7.6%, 7.4%, 7.3%, 8.4%, 7.5%, 7.4%, 8.8%, 8.9%, and 7.6% in each group, respectively. There were no statistically significant differences in clinical pregnancy rates or live birth rates between any groups and those with the post-wash TPMSC <1 × 10 6 . In an IUI program for unexplained and mild male factor infertility, the post-wash TPMSC in the first IUI cycle was not significantly associated with the live birth rate in the second IUI cycle.

OBJECTIVE: To explore the association between acupuncture during controlled ovarian hyperstimulation (COH) and the live birth rate (LBR) using different propensity score methods. METHODS: In this retrospective cohort study, eligible women who underwent a COH were divided into acupuncture and non-acupuncture groups. The primary outcome was LBR, as determined by propensity score matching (PSM). LBR was defined as the delivery of one or more living infants that reached a gestational age over 28 weeks after embryo transfer. The propensity score model encompassed 16 confounding variables. To validate the results, sensitivity analyses were conducted using three additional propensity score methods: propensity score adjustment, inverse probability weighting (IPW), and IPW with a "doubly robust" estimator. RESULTS: The primary cohort encompassed 9751 patients (1830 [18.76%] in the acupuncture group and 7921 [81.23%] in the non-acupuncture group). Following 1:1 PSM, a higher LBR was found in the acupuncture cohort (41.4% [755/1824] vs 36.4% [664/1824], with an odds ratio of 1.23 [95% confidence interval, 1.08-1.41]). Three additional propensity score methods produced essentially similar results. The risk of serious adverse events did not significantly differ between the two groups. CONCLUSION This retrospective study revealed an association between acupuncture and an increased LBR among patients undergoing COH, and that acupuncture is a safe and valuable treatment option.

Intrauterine insemination with donor sperm (IUI-D) is an assisted reproductive technology (ART) offered to couples with definitive male infertility or risk of genetic disease transmission. Here, we sought to evaluate our practice in IUI-D and identify factors that influenced the success rate. We performed a retrospective, single-center study of all IUI-D procedures performed at Lille University Medical Center (Lille, France) between January 1, 2007, and December 31, 2017. Single and multivariate analyses with a mixed logistic model were used to identify factors associated with clinical pregnancies and live births. We included 322 couples and 1179 IUI-D procedures. The clinical pregnancy rate was 23.5%, and the live birth rate was 18.9% per IUI-D. In a multivariate analysis, the women's age was negatively associated with the live birth rate. The number of motile spermatozoa inseminated was the only factor associated with both clinical pregnancies and live births, with a chosen threshold of 0.75 million. The clinical pregnancy and live birth rates were, respectively, 17.3% and 13.0% below the number of motile spermatozoa inseminated threshold and 25.9% and 21.0% at or above the threshold (all P = 0.005). The number of motile spermatozoa inseminated was the only factor that significantly influenced both pregnancies and live-birth rates after IUI-D. Indeed, below a threshold of 0.75 million motile spermatozoa inseminated, those rates were significantly lower. Application of this number of motile spermatozoa inseminated threshold may help centers to allocate donations more effectively while maintaining reasonable waiting times for patients.

OBJECTIVES: The prevalence of intrauterine adhesion (IUA) increased gradually, which seriously affected female reproductive health and fertility. This study aims to analyze the clinical features of pre-, intra-, and post hysteroscopic adhesiolysis (HA) and to identify the main risk factors for non-live birth and other factors affecting pregnancy outcome in patients with IUA. METHODS: A total of 486 IUA patients with reproductive needs, who underwent HA in the third Xiangya Hospital of Central South University from January 2017 to May 2018, were retrospectively included. The follow-up period was 2-3 years after operation. Univariate analysis and multivariate logistic regression analysis were used to explore the relationship between clinical features and live birth rate in patients with IUA. Pre-operative clinical indicators included age, gravidity, parity, abortion, IUA recurrence, menstrual patterns, and disease course. Intraoperative clinical features assessed in the last operation were uterine cavity length, IUA appearance, IUA area, number of visible uterine cornua, number of visible tubal ostia, and American Fertility Society (AFS) scores. The relationship between clinical indicators and postoperative live birth rate was investigated by univariate analysis and multivariate logistic regression analysis. Pregnancy pattern was the main variable. RESULTS: Among the 486 IUA patients included in this study, there were 256 (52.67%) live births and 230 (47.33%) non-live births. Univariate analysis and multivariate logistic regression showed that the live birth rate of in vitro fertilization and embryo transfer (IVF-ET) after HA was higher than that of spontaneous pregnancy (OR=0.557, 95% CI 0.361 to 0.861, P=0.008). When the bilaterally fallopian tube ostia were invisible in the last operation (OR=0.322, 95% CI 0.104 to 0.997, P=0.049), patients were more likely to have live birth. The older the patient was, the lower the live birth rate was (OR=1.081, 95% CI 1.034 to 1.131, P<0.001). The live birth rate would be low when the last AFS score was moderate (OR=2.973, 95% CI to 1.541 to 5.738, P<0.010). CONCLUSIONS Based on the outcome of the first pregnancy after HA, IUA patients' pregnancy patterns, age, number of visible tubal ostia, and AFS scores noted by a second-look hysteroscopy, are the factors influencing the prognosis for the live birth rate in IUA patients. IVF-ET may improve live birth rate for patients with IUA after HA.

BACKGROUND: More and more scholars have called for the cumulative live birth rate (CLBR) of a complete ovarian stimulation cycle as a key indicator for assisted reproductive technology. This research aims to study the CLBR of the first ovarian hyperstimulation cycles and analyze the related prognosis factors that might affect the CLBR. METHODS: Our retrospective study included first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) cycles performed between January 2013 to December 2014. A total of 17,978 couples of first ovarian hyperstimulation IVF/ICSI cycles were included. The study was followed up for 4 years to observe the CLBR. The multivariable logistic regression model was used to analyze the prognosis factor, P value of <0.05 was considered statistically significant. RESULTS: The cumulative pregnancy rate was 58.14% (10,452/17,978), and the CLBR was 49.66% (8928/17,978). The female age was younger in the live birth group when compared with the non-live birth group (30.81 ± 4.05 vs. 33.09 ± 5.13, P < 0.001). The average duration of infertility was shorter than the non-live birth cohort (4.22 ± 3.11 vs. 5.06 ± 4.08, P < 0.001). The preliminary gonadotropin used and the total number of gonadotropin used were lower in the live birth group when compared with the non-live birth group (both P < 0.001). Meanwhile, the number of oocytes retrieved and transferrable embryos were both significantly higher in the live birth group (15.35 ± 7.98 vs. 11.35 ± 7.60, P < 0.001; 6.66 ± 5.19 vs. 3.62 ± 3.51, P < 0.001, respectively). CONCLUSIONS The women's age, body mass index, duration of infertility years, infertility factors, controlled ovarian hyperstimulation protocol, the number of acquired oocytes, and number of transferrable embryos are the prognosis factors that significantly affected the CLBR.

OBJECTIVES: To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications. METHODS: The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants. RESULTS: A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25 CONCLUSIONS The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.

rate, uterine artery Doppler indices, and fetal presentation.RESULTS: We established a specific protocol for the measurement of cervical elastography using the E cervix program. For all elastographic parameters, the intra-observer intraclass correlation coefficient (ICC) ranged from 0.633 to 0.723 for single measures and from 0.838 to 0.887 for average measures, and the inter-observer ICC ranged from 0.814 to 0.977 for single measures and from 0.901 to 0.988 for average measures. Regression analysis showed that the measurement of the elastographic parameter was not affected by baseline clinical factors.CONCLUSION: We present a standardized protocol for the measurement of cervical elastography using intrinsic compression. According to this protocol, reproducibility was acceptable and the measurement of elastographic parameters was not affected by the baseline clinical factors studied.]]>

To compare the cumulative live birth rates (CLBR) and the incidence of ovarian hyperstimulation syndrome (OHSS) between fresh embryo transfer (ET) and frozen ET (the freeze-all policy), when oocyte numbers are more than 15 in the first treatment of in vitro fertilization or intracytoplasmic sperm injection, and to evaluate the benefits of the freeze-all policy.
 Methods: We retrospectively analyzed clinical data of 2 842 patients whose oocytes numbers were more than 15, including 1 095 frozen ET patients and 1 747 fresh ET patients. The patients general data, a baseline features, CLBR, and the incidence of OHSS were compared between the 2 groups.
 Results: There were 598 patients in the 2 groups after they experienced the propensity score matching. No significant differences were found in age, infertility causes, body mass index, basal follicle stimulating hormone level, the total days and total dose of using gonadotrophin (Gn) between the 2 groups (all P>0.05). The CLBR of the freeze-all cycles increased along with the number of oocytes (P>0.05), and the oocyte numbers were greater in freeze-all group than those of the fresh ET group (P<0.001). There was no significant difference in CLBR after one complete cycle between the 2 groups (P>0.05), but after the first embryo transfer cycle, the CLBR in freeze-all group was higher than that in the fresh ET cycle group (P<0.05). The incidence of OHSS in patients with freeze-all was significantly lower than that in the patiants with fresh ET (P<0.05).
 Conclusion: Patients with oocytes over 15 and OHSS tendency who accepted the freeze-all strategy can help them to prevent OHSS and they have a higher CLBR than fresh ET cycles.

Antisperm antibodies (ASAs) are assumed to be a possible causative factor for male infertility, with ASAs detected in 5%-15% of infertile men but in only 1%-2% of fertile ones. It remains unclear whether ASAs have an adverse effect on the outcome of in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). This study investigated differences in the rates of fertilization, pregnancy, and live births associated with serum ASA-positive and ASA-negative men following IVF or ICSI. Five hundred and fifty-four consecutive infertile couples undergoing IVF (n = 399) or ICSI (n = 155) were included. The two-sample two-sided t-test and Chi-square or Fisher's exact test was used for statistical analysis. Lower rates of fertilization (41.7% vs 54.8%, P = 0.03), good embryos (18.9% vs 35.2%, P = 0.00), pregnancy (38.5% vs 59.4%, P = 0.00), and live births (25.8% vs 42.5%, P = 0.00) were observed in men of the IVF group with a positive serum ASA than in those with a negative ASA. ASA positivity/negativity correlated with pregnancy rates (P = 0.021, odds ratio [OR]: 0.630, 95% confidence interval [CI]: 0.425-0.932) and live birth rates (P = 0.010, OR: 1.409, 95% CI: 1.084-1.831) after controlling for the female serum follicle-stimulating hormone level and the couple's ages at IVF. Women coupled with ASA-positive men had lower live birth rates with IVF than with ICSI (25.8% and 47.4%, respectively; P = 0.07). Women coupled with ASA-positive men had lower rates of pregnancy and live births following IVF than those coupled with ASA-negative men but had a similar outcome with ICSI.
