Intracytoplasmic sperm injection versus conventional in-vitro fertilisation for couples with infertility with non-severe male factor: a multicentre, open-label, randomised controlled trial. Lancet 2024; 403:924-934. [PMID: 38330980 DOI: 10.1016/s0140-6736(23)02416-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 10/26/2023] [Accepted: 10/26/2023] [Indexed: 02/10/2024]
Abstract
BACKGROUND Introduced in 1992, intracytoplasmic sperm injection (ICSI) was initially indicated for severe male infertility; however, its use has since been expanded to non-severe male infertility. We aimed to compare the efficacy and safety of ICSI versus conventional in-vitro fertilisation (IVF) in couples with infertility with non-severe male factor. METHODS We conducted an investigator-initiated, multicentre, open-label, randomised controlled trial in ten reproductive medicine centres across China. Couples with infertility with non-severe male factor without a history of poor fertilisation were randomly assigned (1:1) to undergo either ICSI or conventional IVF. The primary outcome was live birth after first embryo transfer. We performed the primary analysis in the intention-to-treat population using log-binomial regression models for categorical outcomes or linear regression models for continuous outcomes, adjusting for centre. This trial is registered with Clinicaltrials.gov, NCT03298633, and is completed. FINDINGS Between April 4, 2018, and Nov 15, 2021, 3879 couples were screened, of whom 2387 (61·5%) couples were randomly assigned (1184 [49·6%] to the ICSI group and 1203 [50·4%] to the conventional IVF group). After excluding couples who were ineligible, randomised twice, or withdrew consent, 1154 (97·5%) in the ICSI group and 1175 (97·7%) in the conventional IVF group were included in the primary analysis. Live birth after first embryo transfer occurred in 390 (33·8%) couples in the ICSI group and in 430 (36·6%) couples in the conventional IVF group (adjusted risk ratio [RR] 0·92 [95% CI 0·83-1·03]; p=0·16). Two (0·2%) neonatal deaths were reported in the ICSI group and one (0·1%) in the conventional IVF group. INTERPRETATION In couples with infertility with non-severe male factor, ICSI did not improve live birth rate compared with conventional IVF. Given that ICSI is an invasive procedure associated with additional costs and potential increased risks to offspring health, routine use is not recommended in this population.

Abstract
This article reviews the evidence regarding the safety and efficacy of intra-cytoplasmic sperm injection (ICSI). It provides evidence-based clinical and laboratory guidelines and recommendations for use of ICSI within an assisted reproductive technology (ART) service. The guidelines address the evidence for the use of ICSI rather than conventional IVF (cIVF); the use of ART techniques supplementary to ICSI; and risks associated with ICSI. This article is not intended to be the only approved standard of practice or to dictate an exclusive course of treatment. Other plans of management may be appropriate, taking into account the needs and medical history of the patient, available resources, and institutional or clinical practice limitations.

Abstract
Latest knowledge assigns the origins of autism spectrum disorder (ASD)-currently affecting 1% of children- to intrauterine life, when fetal brain develops. Besides genetics, environmental factors, responsible for epigenetic changes contributed to its rising incidence. In vitro fertilization (IVF) and the most widely used intracytoplasmic sperm injection (ICSI) are implicated in epigenetic changes. A series of studies examined the impact of ICSI on ASD in the offspring. Results are usually conflicting, due to inherent problems of study design and power, mixed IVF/ICSI cases and not exclusively ASD diagnoses included. Furthermore, preterm birth, low birthweight infants, advanced parental age, hormonal disturbances, all associated with ICSI, are known factors affecting ASD. While solid data supporting ICSI contribution to currently alarming ASD increase are lacking, exploration of underlying molecular mechanisms would strengthen possible associations. In the meanwhile, ICSI use should be restricted to male-factor infertility cases.

Abstract
Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by a wide spectrum of deficits in social interaction, communication, and behavior. There is a significant genetic component to ASD, yet no single gene variant accounts for >1% of incidence. Posttranscriptional mechanisms such as microRNAs (miRNAs) regulate gene expression without altering the genetic code. They are abundant in the developing brain and are dysregulated in children with ASD. Patterns of miRNA expression are altered in the brain, blood, saliva, and olfactory precursor cells of ASD subjects. The ability of miRNAs to regulate broad molecular pathways in response to environmental stimuli makes them an intriguing player in ASD, a disorder characterized by genetic predisposition with ill-defined environmental triggers. In addition, the availability and extracellular stability of miRNAs make them an ideal candidate for biomarker discovery. Here, we discuss 27 miRNAs with overlap across ASD studies, including 3 miRNAs identified in 3 or more studies (miR-23a, miR-146a, and miR-106b). Together, these 27 miRNAs have 1245 high-confidence mRNA targets, a significant number of which are expressed in the brain. Furthermore, these mRNA targets demonstrate over-representation of autism-related genes with enrichment of neurotrophic signaling molecules. Brain-derived neurotrophic factor, a molecule involved in hippocampal neurogenesis and altered in ASD, is targeted by 6 of the 27 miRNAs of interest. This neurotrophic pathway represents one intriguing mechanism by which perturbations in miRNA signaling might influence central nervous system development in children with ASD.
