Cumulative live birth rate of a blastocyst versus cleavage stage embryo transfer policy during in vitro fertilisation in women with a good prognosis: multicentre randomised controlled trial.

Objectives: To evaluate whether embryo transfers at blastocyst stage improve the cumulative live birth rate after oocyte retrieval, including both fresh and frozen-thawed transfers, and whether the risk of obstetric and perinatal complications is increased compared with cleavage stage embryo transfers during in vitro fertilisation (IVF) treatment.

Design: Multicentre randomised controlled trial.

Setting: 21 hospitals and clinics in the Netherlands, 18 August 2018 to 17 December 2021.

Barriers and facilitators for the implementation of co-created nursing innovations in a Dutch university hospital.

Introduction: Escalating global nursing shortages require solutions for efficient care, fewer injuries and lost workdays. When commercial solutions are lacking, innovations developed through co-creation can be a viable alternative. However, many co-created nursing innovations are ineffectively implemented.

Testing on bacterial vaginosis in a subfertile population and time to pregnancy: a prospective cohort study.

Purpose: This study aimed to investigate the influence of bacterial vaginosis on time to pregnancy in subfertile couples.

Methods: Couples attending a teaching hospital in the Netherlands having an initial fertility assessment (IFA) between July 2019 and June 2022 were included in this prospective study, with follow-up of pregnancies until June 2023. Vaginal samples at IFA were analyzed on pH, qPCR BV, and 16S rRNA gene microbiome analysis of V1-V2 region.

The Vaginal Microbiome Changes During Various Fertility Treatments.

This study aimed to investigate the influence of hormonal treatment on the vaginal microbiome during fertility treatments. Bacterial vaginosis (BV) could affect fecundity, particularly in the in vitro fertilization (IVF) population, where negative effects on pregnancy outcomes have been reported. It is hypothesized that the hormone treatment during fertility treatments could influence the abundance of Lactobacilli, with negative effects on the pregnancy results.

Bacterial vaginosis in a subfertile population undergoing fertility treatments: a prospective cohort study.

Purpose: This study investigates the role of bacterial vaginosis (BV) on pregnancy rates during various fertility treatments. BV is known to influence several obstetric outcomes, such as preterm delivery and endometritis. Only few studies investigated the effect of BV in subfertile women, and studies found a negative effect on fecundity especially in the in vitro fertilisation population.
