Objectives: This meta-analysis aimed to evaluate congenital malformations in infants conceived by assisted reproductive techniques (ART), compared with infants conceived spontaneously.
Methods: In this study, available resources searched to find relevant articles included PubMed, ScienceDirect, Scopus, Google Scholar, Cochrane, ProQuest, Iranmedex, Magiran, and Scientific Information Database. After extracting the necessary information from evaluated articles, meta-analysis on the articles' data was performed using Stata version 11.2.
Results: In this study, from a total of 339 articles, extracted from the initial investigation, ultimately 30 articles were selected for meta-analysis that assessed the use of ART on the risk of congenital abnormalities and some birth complications on 5 470 181 infants (315 402 cases and 5 154 779 controls). The odds ratio (95% confidence interval [CI]) for low birth weight was 1.89 (95% CI, 1.36 to 2.62), preterm labor 1.79 (95% CI, 1.21 to 2.63), cardiac abnormalities 1.43 (95% CI, 1.27 to 1.62), central nervous system abnormalities 1.36 (95% CI, 1.10 to 1.70), urogenital system abnormalities 1.58 (95% CI, 1.28 to 1.94), musculoskeletal disorders 1.35 (95% CI, 1.12 to 1.64), and chromosomal abnormalities in infants conceived by ART was 1.14 (95% CI, 0.90 to 1.44), which were all statistically significant, except chromosomal abnormalities.
Conclusions: The risk of congenital abnormalities and some birth complications were significantly higher in ART than normal conception, while chromosomal abnormalities were not; therefore, the application of ART should be selected individually for patients by detailed assessment to reduce such risks in the population.

Background: Maternal primary cytomegalovirus (CMV) infection is associated with abortion and congenital anomalies. In Uganda, the burden of maternal CMV infection is not well studied. This study thus assessed the seroprevalence and factors associated with CMV infection among pregnant women at Kawempe National Referral Hospital in Kampala.

Background: In vitro fertilisation (IVF) offers a solution for infertility but poses increased obstetrical and perinatal risks, including higher rates of preterm birth, low birth weight and congenital anomalies. Particularly, IVF-related multiple pregnancies face significantly higher risks for preterm birth and prolonged hospital stays. This study compares neonatal outcomes between IVF and natural conception, as well as between singleton and IVF-related multiple pregnancies over the past decade.

Study Question: Is paternal age associated with neonatal outcomes?
Summary Answer: Paternal age is independently associated with preterm birth (PTB) and caesarean section.
What Is Known Already: Advanced maternal age has long been recognized as a major risk factor for adverse neonatal outcomes. However, the association between paternal age and neonatal outcomes are not well established, yet it is biologically plausible that an increasing number of genetic and epigenetic sperm abnormalities in older males may contribute to adverse neonatal outcomes.

Background: This study aimed to develop a new ultrasonographic dating formula to estimate gestational age (GA) based on fetal crown-rump length (CRL) in a Chinese population, evaluate model accuracy and compare its performance with established dating formulas.
Methods: A prospective, multicenter study was conducted across mainland China. Participants included healthy, low-risk women with spontaneously conceived singleton pregnancies and a regular menstrual cycle in the preceding year.

Background: In previous studies, the incidences of premature births and large for newborn gestational age (LGA ) infants were higher with blastocyst transfer than with cleavage-stage embryo transfer in infants conceived via frozen embryo transfer (FET) cycles. However, those previous studies reported unbalanced baseline characteristics between the blastocyst transfer group and the cleavage embryo transfer group. Therefore, in this study, we used propensity score matching to compare the birth weight and newborn gestational age of live-born singletons between blastocyst and cleavage-stage embryo transfer in FET cycles.
