Diverse developmental velocities of blastocyst development emerge as early as a few hours after insemination: morphokinetic analysis of fertilisation in days 4-7 blastocysts.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-025-03476-8

PurposeThe time at which embryo developmental velocity variations occur remains unknown. Therefore, we analysed the morphokinetic trajectory of human early fertilisation from the extrusion of the second polar body (PB2) to pronuclear breakd…

Maternal and obstetric outcomes following the transfer of embryos warmed with fatty acid-supplemented solutions.
BMC pregnancy and childbirth ·doi:10.1186/s12884-024-06546-4

BackgroundVitrification procedures decrease intracytoplasmic lipid content and impair developmental competence. Adding fatty acids (FAs) to the warming solution has been shown to recover the lipid content of the cytoplasm and improve develo…

Comparison of 1-year cumulative live birth and perinatal outcomes following single blastocyst transfer with or without preimplantation genetic testing for aneuploidy: a propensity score-matched study.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-023-02926-5

PurposeWe evaluated whether preimplantation genetic testing for aneuploidy (PGT-A) could increase the cumulative live birth rate (CLBR) in patients with recurrent implantation failure (RIF) and recurrent pregnancy loss (RPL).MethodsThe clin…

Fatty acid supplementation into warming solutions improves pregnancy outcomes after single vitrified-warmed cleavage stage embryo transfers.
Reproductive medicine and biology ·doi:10.1002/rmb2.12517

PurposeThis study aimed to examine the embryonic development of human 4-cell stage embryos after warming with fatty acids (FAs) and to assess the pregnancy outcomes after single vitrified-warmed cleavage stage embryo transfers (SVCTs).Metho…

Prevalence of chronic endometritis in patients with infertility due to hydrosalpinx or pelvic peritubal adhesions and effect of laparoscopic surgical correction on pregnancy rates post in vitro fertilization
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/j.ejogrb.2023.03.021

OBJECTIVE(S): To assess the prevalence of chronic endometritis (CE) in patients with infertility and hydrosalpinx or peritubal adhesions and to examine the effects of laparoscopic surgical correction (LSC) on CE and pregnancy rates post in …

Correlation between an annotation-free embryo scoring system based on deep learning and live birth/neonatal outcomes after single vitrified-warmed blastocyst transfer: a single-centre, large-cohort retrospective study.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-022-02562-5

ProposeDoes an annotation-free embryo scoring system based on deep learning and time-lapse sequence images correlate with live birth (LB) and neonatal outcomes?MethodsPatients who underwent SVBT cycles (3010 cycles, mean age: 39.3 ± 4.0). S…

Comparing prediction of ongoing pregnancy and live birth outcomes in patients with advanced and younger maternal age patients using KIDScore™ day 5: a large-cohort retrospective study with single vitrified-warmed blastocyst transfer.
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-021-00767-4

BackgroundThe KIDScore™ Day 5 (KS-D5) model, version 3, is a general morphokinetic prediction model (Vitrolife, Sweden) for fetal heartbeat prediction after embryo transfer that was developed based on a large data set that included implanta…

Comparison of pregnancy outcomes following fresh and electively frozen single blastocyst transfer in natural cycle and clomiphene-stimulated IVF cycles.
Human reproduction open ·doi:10.1093/hropen/hoy006

Study questionAre there any differences in live birth rates (LBR) following fresh blastocyst transfer in natural or clomiphene-stimulated cycles, or after elective blastocyst freezing in clomiphene-stimulated cycles followed by thawing and …

Surgical procedure to conserve the uterus for future pregnancy in patients suffering from massive adenomyosis
Reproductive biomedicine online ·doi:10.1016/j.rbmo.2010.09.014

The treatment for severe adenomyosis has usually been hysterectomy, because there is no line of demarcation between diseased and normal tissue. Yet many such women wish to retain their uterus and some even wish to bear children. This report…

Long-term follow-up on the treatment of endometriosis with the GnRH-agonist buserelinacetate Long-term follow-up data (up to 98 months) of 42 patients with endometriosis who were treated with GnRH-agonist buserelinacetate (Suprecur®), were evaluated in respect of recurrence of pain symptoms and pregnancy outcome
European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/s0301-2115(97)02733-4

ObjectiveIn our previous study, 119 patients with histologically confirmed endometriosis underwent a 'three-step' therapy between 1987 and 1989, where surgical removal of endometriosis was followed by a 6 month treatment with 3 x 300 microg…
