The Association Between Previous TORCH Infections and Pregnancy and Neonatal Outcomes in IVF/ICSI-ET: A Retrospective Cohort Study.

ABSTRACT: Objective: This study aimed to investigate the associations between previous TORCH infection (cytomegalovirus, toxoplasmosis, herpes simplex virus, and rubella) with pregnancy and neonatal outcomes in couples undergoing IVF/ICSI-ET. Materials and Methods: A total of 18,074 couples underwent fresh IVF/ICSI-ET (in vitro fertilization/intracytoplasmic sperm injection-embryo transfer) cycles were included in our analyses. TORCH infection status was determined by serological confirmation of cytomegalovirus, toxoplasmosis, herpes simplex virus, and rubella IgG in the absence of IgM antibodies. Clinical pregnancy, ectopic pregnancy, miscarriage, live birth, preterm birth, congenital malformation, and perinatal death were evaluated in both infection and non-infection group. Multivariate logistic regression was applied to calculate odds ratio. Results: Previous toxoplasmosis infection is associated with a significantly decreased preterm birth rate [P = 0.045, OR = 0.755 (95% CI, 0.571-0.997), Adjusted OR = 0.749 (95%CI, 0.566-0.991)]. No differences in clinical pregnancy, ectopic pregnancy, miscarriage, and perinatal death were observed between the corresponding TORCH infection group [IgM (-) IgG(+)] and the non-infection group [IgM (-) IgG (-)]. Conclusions: Previous TORCH infections were not associated with adverse pregnancy and neonatal outcomes in IVF/ICSI-ET overall, and toxoplasmosis infection might be associated with a lower preterm birth rate in patients underwent IVF/ICSI-ET. The necessity of TORCH IgG screening in IVF procedure might need re-evaluation, and further cost-effective analysis might be helpful for the clinical management strategy.

Project description:ObjectiveTo investigate the effect of the early blastocyst on pregnancy and birth outcomes in patients in vitro fertilization/(early rescue) intracytoplasmic sperm injection-embryo transfer [IVF/(early rescue)ICSI-ET] cycles.MethodsIn this retrospective cohort study, 289 patients with single-blastocyst transfer within IVF/(early rescue)ICSI-ET treatment cycle were included and divided into the early (n = 48, Gardner stage = 1 or 2) and the fully expanded blastocyst (n = 241, Gardner stage ≥ 3) groups. The differences in pregnancy and birth outcomes between the two groups were compared.ResultsThere was no significant differences between the two groups in baseline indicators, including demographic characteristics and clinical treatment (P> 0.05).The clinical outcomes indicators in the early and the fully expanded blastocyst groups were compared, including the number of transferable embryos on the third day (D3)5.0 (4.0, 6.8) vs. 6.0 (5.0, 8.0) (P = 0.001), the number of remaining embryos frozen per cycle 1.0 (0.3, 2.0) vs. 3.0 (2.0, 5.0) (P<0.001); the number of cycles of unfrozen embryos 13/48 (27.1%) vs. 12/241 (5.0%) (P<0.001); the pregnancy outcome including the clinical pregnancy rate (CPR) 20/48 (41.7%) vs. 129/241 (53.5%) (P>0.05); the live birth rate (LBR)15/48 (31.3%) vs.106/241 (44.0%) (P>0.05). There were no significant differences in birth outcomes, such as gestational week of labor, mode of delivery, neonatal birth weight, height, Apgar score, sex ratio, and birth defects between the two groups (P>0.05).Multivariate binary logistic regression showed the same result, i.e., early blastocyst transfer in fresh cycle was not a risk factor for clinical pregnancy (OR = 0.516, 95% CI = 0.260-1.022) and live birth (OR = 0.521, 95% CI = 0.252-1.079).ConclusionCompared with the fully expanded blastocyst group, the CPR and LBR in the early blastocyst group of the fresh transfer cycles were relatively ideal, and there were no significant differences in birth outcomes and neonatal status between the two groups.

Project description:ObjectiveTo study the impact of congenital uterine anomalies on reproductive outcomes after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI)-embryo transfer (ET).MethodsA retrospective study including a total of 865women with congenital uterine anomalies and 865 age and admission time matched controls who underwent the first IVF/ICSI-ET cycle between January 2010 and December 2019 was conducted. Women with uterine anomalies were classified into canalization defect (complete septate uterus and subseptate uterus) and unification defect (unicornuate uterus, bicornuate uterus, and didelphus uterus) according to the processes of abnormal embryological development. Control women were selected by age (± 1.0 year) and admission time (± 6 months) matched with a 1:1 ratio. The reproductive outcomes were compared between women with uterine anomalies and the controls. The primary outcome was live birth; secondary outcomes were clinical pregnancy, ectopic pregnancy, preterm delivery, and spontaneous pregnancy loss.ResultsCompared with women with a normal uterus, women with canalization defects were less likely to experience live birth [84/332 (25.3%) vs 128/332 (38.6%), RR: 0.647, 95% CI 0.513-0.815, P < 0.001]. They also had a lower clinical pregnancy rate [126/332 (38.0%) vs 206/332 (62.0%), RR: 0.829, 95% CI 0.690-0.997, P = 0.046] and experienced a higher first-trimester pregnancy loss rate [25/126 (19.8%) vs 11/206 (5.3%), RR: 2.716, 95% CI 1.393-5.295, P = 0.003]. Compared with women with a normal uterus, women with a unification defect were also less likely to experience live birth [132/533 (24.8%) vs 219/533 (41.1%), RR: 0.713, 95% CI 0.586-0.868, P = 0.001]. Women with a unification defect had lower clinical pregnancy rates [182/533 (34.1%) vs 263/533 (49.1%), RR: 0.813, 95% CI 0.695-0.952, P = 0.010] and increased first-trimester pregnancy loss [36/182 (19.8%) vs 20/263 (7.6%), RR: 3.288, 95% CI 1.776-6.085, P < 0.001]. While uterine anomaly seemed not increase the risk of preterm birth, ectopic pregnancy and second-trimester pregnancy loss.ConclusionsBoth canalization defects and unification defects were associated with lower fertility outcomes, including lower live birth rates, lower clinical pregnancy rates, and higher early miscarriage rates.

Project description:We investigated the prevalence of human papillomavirus (HPV) infection in the female partner of infertile couples and the reproductive outcomes after in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET). We conducted a retrospective analysis on 8117 women from infertile couples who underwent IVF/ICSI treatment and evaluated the prevalence of HPV infection in these women. The prevalence of HPV infection in the female partner of infertile couples was 9.2% (747/8117). These HPV-infected female patients undergoing ART were divided into high-risk HPV (hrHPV) (n = 130) and low-risk HPV (lrHPV) groups (n = 94), and non-infected women patients formed the negative group (n = 126). Of the 747 cases infected with HPV, 529 showed hrHPV infection (70.82%; primarily genotypes 16, 52, 53, 58, and 59); 175 exhibited lrHPV infection (23.43%; primarily genotypes 6, 43, 44, 55, 61, and 81); and 43 cases were co-infected with hrHPV and lrHPV (5.76%). Except for the Day-3 high-quality embryo rate, there were no differences in ovum maturation, fertilization, implantation, clinical pregnancy, live birth, or miscarriage rates between women infected with HPV and non-infected women (p > 0.05); however, we noted an increased miscarriage rate after logistic regression analyses (OR, 0.16; 95% CI, 0.03-0.84; p = 0.041). For single-male-factor-induced infertility in couples (smHPV), although we likewise observed no differences in ovum maturation, fertilization, or implantation rates (p > 0.05) between the smHPV group and the negative group, we discerned diminutions in the Day-3 high-quality embryo rate (46.01% vs. 70.04%, p = 0.013), clinical pregnancy rate (46.67% vs. 57.94%, p = 0.003), and live birth rate (33.33% vs. 46.83%, p = 0.027) as well as an augmented miscarriage rate (11.11% vs. 4.76%, p = 0.003), respectively. Logistic regression analyses indicated that smHPV was a risk factor for decreased clinical pregnancy rate (OR, 4.17; 95% CI, 2.31-7.53; p < 0.001) and live birth rate (OR, 1.83; 95% CI, 0.81-2.14; p = 0.045) and elevated miscarriage rate (OR, 6.83; 95% CI, 2.22-21.00; p = 0.001). HPV infection in women was associated with increased miscarriage rate, and single-male-factor infertility influenced reproductive outcomes in couples undergoing IVF/ICSI treatment. Both were potentially due to HPV infection in the couple.
