Assisted reproductive technologies and the risk of congenital urogenital tract malformations: A systematic review and meta-analysis. J Pediatr Urol 2021; 17:9-20. [PMID: 33223458 DOI: 10.1016/j.jpurol.2020.11.005] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 10/24/2020] [Accepted: 11/03/2020] [Indexed: 11/21/2022]
Abstract
A systematic review was conducted to evaluate the relationship between ART and the risk of urogenital tract malformations, especially hypospadias and cryptorchidism. Thirty-three papers were selected. Meta-analysis showed that ART was correlated with an increased risk of urogenital tract malformation in offspring (odds ratio (OR) = 1.61, 95% confidence interval (CI): 1.41-1.85), hypospadias (OR = 1.87, 95% CI: 1.47-2.40) and cryptorchidism (OR = 1.83, 95% CI: 1.54-2.18). Among offspring conceived by ART, multiple pregnancies appeared to result in a higher risk of urogenital tract malformation than singleton pregnancies (OR = 1.42, 95% CI: 0.99-2.04; P = 0.058). No significant difference in the risk of urogenital tract malformation was found between in vitro fertilization and intracytoplasmic sperm injection technologies. A sensitivity analysis showed that the above conclusions were relatively consistent. Conclusion: ART is correlated with an increased risk of urogenital tract malformations in offspring, especially hypospadias and cryptorchidism. Among ART offspring, multiple pregnancies may lead to a higher risk of urogenital tract malformations than singleton pregnancies, but more studies are needed for confirmation.

Abstract
Abstract
Background
The use of assisted reproductive technology (ART) is increasing worldwide, and observational studies have indicated that women who conceived by ART have an increased risk of pregnancy complications including gestational diabetes mellitus (GDM). We aimed to determine the risk of GDM among women who conceived with ART by systematic review and meta-analysis.
Main text
A systematic literature search was conducted in ISI Web of Knowledge, MEDLINE, Scopus, and Embase through May 2017 for English-language articles using a list of keywords. All studies comparing GDM in women conceived by ART and those who conceived spontaneously were included. Data extraction was performed by two authors independently and discrepancies were resolved by discussion. In total, 48 studies with 91,487 pregnancies conceived through ART and 2,525,234 spontaneously conceived met the inclusion criteria. There was evidence of substantial heterogeneity among these studies (P < 0.001, I2 = 98.6%). Random effects meta-analysis showed a significant increase in GDM among those who conceived by ART compared with those who conceived spontaneously (pooled relative risk = 1.51, 95% confidence interval = 1.18–1.93). Visual inspection of the funnel plot did not reveal any publication bias, which was supported by Egger’s test and Begg’s test.
Conclusion
The findings of this systematic review indicate that the use of ART treatment is associated with a 1.51-fold increase in GDM. Women need to be counselled carefully before undergoing ART treatment about the possibility and risk of GDM.

Abstract
OBJECTIVE The use of assisted reproductive technology (ART) has been associated with an increased risk of gestational diabetes mellitus (GDM) in previous studies, but its risk has not been consistent. Therefore, we aimed to estimate the risk of GDM in women who conceived with ART via a systematic review and meta-analysis of cohort studies. METHODS ISI Web of Knowledge, Medline/PubMed, Scopus, and Embase databases were searched to identify studies that evaluated the risk of GDM through May 2017 using the relevant keywords. Two reviewers independently performed the screening, data extraction, and quality assessment. Meta-analysis was performed with a random effects model. RESULTS The search yielded 957 records relating to GDM and use of ART, from which 59 eligible cohorts were selected for meta-analysis (n = 96,785). There was evidence of substantial heterogeneity among these studies (χ(58)2 = 3072.34, p < .001; I2=98.1%). The pooled estimate of GDM risk using the random effects model was 9.00% (95% CI: 7.90-10.20). Visual inspection of the funnel plot indicated the presence of low publication bias, but Egger's test did not reveal publication bias. CONCLUSIONS The findings revealed that the risk of GDM was very high among women who conceived with ART treatment. GDM screening, management, and improved care are vital in ART pregnancy.

Abstract
Background: Assisted reproductive technologies (ARTs) have made great progress. However, whether tube baby born after ART were at an increased risk of birth defects is not clear.Objective: To assess whether the ART increases the risk of birth defects in children born after ART.Search strategy: Medline, Google Scholar, and the Cochrane Library were searched.Selection criteria: Clinical trials that evaluate the risk of birth defect in children born after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) and natural conceptions (NC) were included. The primary outcome was the prevalence of birth defects.Data collection and analysis: The relative risk was used as the summary measure with random effects model. We assessed heterogeneity between studies using the I2 index.Main results: Totally 46 studies were included. The pooled relative risk (RR) estimated suggested there was an increased risk of birth defects in ART compared with the NC group (RR: 1.40; 95% CI 1.31-1.49). Twenty and fifteen studies were included to compare the risk of birth defects between NC and IVF/ICSI, respectively. The results indicated that both IVF and ICSI increase the risk of birth defects (IVF: RR 1.25; 95% CI 1.12-1.40; ICSI: RR 1.29; 95% CI 1.14-1.45). When subgroup according to plurality, 22 studies assessed the risk of birth defects after ART or NC in singletons and 15 studies evaluated the risk of birth defects in twins. The pooled RRs were 1.41 (95% CI 1.30-1.52) and 1.18 (95% CI 0.98-1.42), respectively.Conclusions: Children born after ART were at an increased risk of birth defects compared with NC. There was no difference in birth defects risk between ART twins and NC twins.

Abstract
Studies comparing risk of specific congenital malformations (CM) between multiple pregnancies resulting from IVF/intracytoplasmic sperm injection (ICSI) and those conceived naturally report conflicting results; furthermore, there is a lack of a complete overview. This meta-analysis aimed to address which types of CM are increased in IVF/ICSI multiple pregnancies compared with those conceived naturally. All studies testing the association between IVF/ICSI multiple pregnancies and specific CM identified in various databases were considered. The literature search yielded 856 records, of which 21 cohort studies were included for analysis. Overall, multiple pregnancies achieved with IVF/ICSI experienced a significantly higher risk of chromosomal defects (relative risk [RR] = 1.36; 95% confidence interval [CI]: 1.04-1.77), urogenital (RR = 1.18; 95% CI: 1.03-1.36) and circulatory (RR = 1.22; 95% CI: 1.01-1.47) system malformations. However, the remaining specific CM, such as cleft lip and/or palate, eye, ear, face and neck, respiratory, musculoskeletal, nervous and digestive system malformations, were similar in the two groups. No substantial heterogeneity was observed for most outcomes except for digestive (P = 0.094; I2 = 38.3%) and circulatory (P = 0.070; I2 = 35.2%) system malformations. These findings provide additional information on risks of IVF/ICSI for use when counselling patients.

Abstract
PURPOSE To assess the association between assisted reproductive technology (ART) and risk of congenital malformations (CM) by conducting a meta-analysis of cohort studies. METHODS PubMed, Google Scholar, Cochrane Libraries and Chinese database were searched through August 2014 to identify studies that met pre-stated inclusion criteria. Either a fixed- or a random-effects model was used to calculate the overall combined risk estimates. Subgroup analysis was performed to explore potential heterogeneity moderators. RESULTS Fifty-seven studies involving 119,874 infants conceived following ART and 1,212,320 infants conceived naturally were included in the analysis. The ART-conceived infants were associated with a higher risk of CM [relative risk (RR) = 1.33; 95 % confidence interval (CI) 1.24-1.43] when compared with those conceived naturally. When data were restricted to singleton births (RR = 1.38; 95 % CI 1.30-1.47), major CM (RR = 1.47; 95 % CI 1.29-1.68), matched/adjusted studies (RR = 1.37; 95 % CI 1.27-1.47) or high quality studies (RR = 1.40; 95 % CI 1.27-1.55), the increased risk of CM still existed in ART pregnancies. Additionally, an increased risk of CM was also found when the ART twin (RR = 1.18; 95 % CI 1.06-1.32) or multiple births (RR = 1.16; 95 % CI 1.05-1.27) were separately compared with spontaneously conceived twin or multiple births. Substantial heterogeneity was observed across studies (I (2) = 68, 44, 39, and 33 % for all infants, singletons, twins and multiples, respectively). Whether confounding factors were matched or adjusted, study quality and sample size as the first three of the most relevant heterogeneity moderators have been identified. No evidence of publication bias was observed (P > 0.10). CONCLUSIONS The ART-conceived infants have a higher risk of CM compared with those conceived naturally. However, these estimates have to be viewed with caution because of heterogeneity.

Abstract
Hypertensive complications in pregnancy are the leading cause of maternal morbidity, at least in the developed countries. In recent years, infertility issues are managed with ever growing therapeutic options namely assisted reproductive technologies (ART), which improve the ratio of successful induction of pregnancy. It is still debated whether various ART modalities are associated with adverse pregnancy outcomes, including hypertensive complications, particularly with higher incidence of preeclampsia. The main source of controversy stems from the diversity of effect modifiers modulating the association between ART-oriented pregnancy and hypertensive disorders. Indeed, women undergoing an ART procedure are affected by diverse causes of infertility, are frequently characterized by different genetic patterns with respect to their artificially conceived embryo and experienced multiple gestations. In order to investigate whether ART modalities are associated with increased incidence of hypertensive complications in pregnancy, we reviewed all published studies carried out before the end of 2010 and identified in the PubMed database. Among the 47 studies finally selected and by acknowledging the potential of shortcomings related to the different study design and populations, the overall evidence suggests that ART-oriented pregnancies-especially the in-vitro fertilization techniques-are accompanied by increased risk for gestational hypertension and preeclampsia as compared with non-ART pregnancies, even after adjustment for confounders. Multiple gestations, advanced age and underlying polycystic ovary syndrome resulted in constant confounders of the questioned association. Reducing multiple gestations by implementing single embryo techniques might be the therapeutic limiting step to lower the rate of hypertensive complications in assisted pregnancies.

Abstract
OBJECTIVE To conduct a meta-analysis of studies assessing the effect of IVF and intracytoplasmic sperm injection (ICSI) on birth defects. DESIGN Meta-analysis. SETTING Centers for reproductive care. PATIENT(S) Patients treated by IVF and/or ICSI. INTERVENTION(S) We identified all studies published by September 2011 with data related to birth defects in children conceived by IVF and/or ICSI compared with spontaneously conceived children, or birth defects in the children conceived by IVF compared with those by ICSI. Risk ratios from individual studies were pooled with the fixed and random effect models. MAIN OUTCOME MEASURE(S) Risk of birth defects in children conceived by IVF and/or ICSI. RESULT(S) Of 925 studies reviewed for eligibility, 802 were excluded after screening titles and abstracts, 67 were excluded for duplicated data, data unavailable, or inappropriate control group, 56 were included in the final analysis. Among the 56 studies, 46 studies had data on birth defects in children conceived by IVF and/or ICSI (124,468) compared with spontaneously conceived children. These studies provided a pooled risk estimation of 1.37 (95% confidence interval [CI]: 1.26-1.48), which is also evident in subgroup analysis. In addition, 24 studies had data on birth defects in children conceived by IVF (46,890) compared with those by ICSI (27,754), which provided an overall no risk difference. CONCLUSION(S) Children conceived by IVF and/or ICSI are at significantly increased risk for birth defects, and there is no risk difference between children conceived by IVF and/or ICSI.

Abstract
BACKGROUND Extremely low birth weight twins have a higher rate of death or neurodevelopmental impairment than singletons. Higher-order extremely low birth weight multiple births may have an even higher rate of death or neurodevelopmental impairment. METHODS Extremely low birth weight (birth weight 401-1000 g) multiple births born in participating centers of the Neonatal Research Network between 1996 and 2005 were assessed for death or neurodevelopmental impairment at 18 to 22 months' corrected age. Neurodevelopmental impairment was defined by the presence of 1 or more of the following: moderate to severe cerebral palsy; mental developmental index score or psychomotor developmental index score less than 70; severe bilateral deafness; or blindness. Infants who died within 12 hours of birth were excluded. Maternal and infant demographic and clinical variables were compared among singleton, twin, and triplet or higher-order infants. Logistic regression analysis was performed to establish the association between singletons, twins, and triplet or higher-order multiples and death or neurodevelopmental impairment, controlling for confounding variables that may affect death or neurodevelopmental impairment. RESULTS Our cohort consisted of 8296 singleton, 2164 twin, and 521 triplet or higher-order infants. The risk of death or neurodevelopmental impairment was increased in triplets or higher-order multiples when compared with singletons (adjusted odds ratio: 1.7 [95% confidence interval: 1.29-2.24]), and there was a trend toward an increased risk when compared with twins (adjusted odds ratio: 1.27 [95% confidence: 0.95-1.71]). CONCLUSIONS Triplet or higher-order births are associated with an increased risk of death or neurodevelopmental impairment at 18 to 22 months' corrected age when compared with extremely low birth weight singleton infants, and there was a trend toward an increased risk when compared with twins.

Abstract
OBJECTIVE To assess the association between in vitro fertilization (IVF) with or without intracytoplasmic sperm injection (ICSI) and adverse birth outcomes. STUDY DESIGN Retrospective cohort study involved IVF/ICSI patients who were treated in the Ottawa Fertility Centre from 1996 to 2005 with a viable pregnancy (>20 weeks of gestation) and mothers who conceived naturally. RESULTS Eleven of the 1044 infants conceived with IVF/ICSI (1.1%) and 7 of the 1910 naturally conceived infants (0.4%) had congenital heart defects (P<0.01). Five of the 138 infants (3.6%) born to mothers with a body mass index>30 and conceived by IVF/ICSI had congenital heart defects, compared with none in the 240 infants born to mothers with a body mass index>30 and conceived naturally (P<0.01). CONCLUSION Infants conceived with use of IVF/ICSI have three times as high a risk of a congenital heart defect as naturally conceived infants.

Abstract
This review focuses on the outcome, merits and demerits of intracytoplasmic sperm injection (ICSI) for treatment of male factor infertility. Spermatozoa of infertile men are surgically retrieved from the epididymis or testis. Fertilisation and pregnancy rates after ICSI are found to be around 66% and 48%, respectively, with surgically retrieved spermatozoa. Major contributing factors to failed fertilisation after ICSI are the number of metaphase II oocytes retrieved and availability of viable spermatozoa for injection. Children born after ICSI have an increased risk of major congenital deformity as compared with children born naturally. Both paternal and maternal risk factors seem to pose an increased risk of congenital malformations in the offspring born after ICSI. The ICSI technique per se is not an independent risk factor. Qualitative differences in development and social interaction between ICSI and natural children appears to be related to developmental processes of the entire family unit. Parents of ICSI children have a good relationship with their children.
