Efficacy of clindamycin and LACTIN-V for in vitro fertilization patients with vaginal dysbiosis: a randomised double-blind, placebo-controlled multicentre trial.
Nature communications ·doi:10.1038/s41467-025-60205-6

The primary aim of the present randomised, double-blind, placebo-controlled trial was to investigate whether clindamycin and live Lactobacillus crispatus CTV-05 (LACTIN-V) would improve clinical pregnancy rates in IVF patients with abnormal…

IVF versus ICSI in patients without severe male factor infertility: a randomized clinical trial.
Nature medicine ·doi:10.1038/s41591-025-03621-x

Intracytoplasmic sperm injection (ICSI) and conventional in vitro fertilization (c-IVF) are widely used fertilization techniques in assisted reproduction, but their relative effectiveness in patients without severe male factor infertility r…

Maternal-Fetal Outcomes and Antibody Transfer, Depending on the Trimester of SARS-CoV-2 Infection in Non-Vaccinated Women-A Danish Nationwide Prospective Cohort Study.
International journal of molecular sciences ·doi:10.3390/ijms26062533

Passive maternal-fetal transfer of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies has been demonstrated, whilst the degree of transfer depending on the trimester of infection is lacking. Due to neonates' immature im…

Vaginal microbiota correlations to gynecological symptoms, intimate hygiene practices, and background parameters of IVF patients: a cross-sectional study.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-025-03629-9

PurposeTo investigate baseline parameters and vaginal intimate hygiene habits comparing IVF patients with and without vaginal dysbiosis, a cross-sectional study.MethodsPatients were grouped by the presence of vaginal dysbiosis status determ…

In vitro fertilisation (IVF) versus intracytoplasmic sperm injection (ICSI) in patients without severe male factor infertility: study protocol for the randomised, controlled, multicentre trial INVICSI.
BMJ open ·doi:10.1136/bmjopen-2021-051058

IntroductionOver the last decades, the use of intracytoplasmic sperm injection (ICSI) has increased, even among patients without male factor infertility. The increase has happened even though there is no evidence to support that ICSI result…

Freeze-all versus fresh blastocyst transfer strategy during in vitro fertilisation in women with regular menstrual cycles: multicentre randomised controlled trial.
BMJ (Clinical research ed.) ·doi:10.1136/bmj.m2519

ObjectiveTo compare the ongoing pregnancy rate between a freeze-all strategy and a fresh transfer strategy in assisted reproductive technology treatment.DesignMulticentre, randomised controlled superiority trial.SettingOutpatient fertility …

Prediction of the lower serum anti-Müllerian hormone threshold for ovarian stimulation prior to in-vitro fertilization using the Elecsys® AMH assay: a prospective observational study.
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-019-0452-4

BackgroundIn assisted reproductive technology, prediction of treatment failure remains a great challenge. The development of more sensitive assays for measuring anti-Müllerian hormone (AMH) has allowed for the possibility to investigate if …

2017
Comparison of a 'freeze-all' strategy including GnRH agonist trigger versus a 'fresh transfer' strategy including hCG trigger in assisted reproductive technology (ART): a study protocol for a randomised controlled trial.
BMJ open ·doi:10.1136/bmjopen-2017-016106

IntroductionPregnancy rates after frozen embryo transfer (FET) have improved in recent years and are now approaching or even exceeding those obtained after fresh embryo transfer. This is partly due to improved laboratory techniques, but may…
