Effect of endometriosis and adenomyosis on oocyte quality: an evaluation of 205,978 oocytes
Reproductive biomedicine online ·doi:10.1016/j.rbmo.2025.105234

RESEARCH QUESTION: Does the presence of endometriosis and/or adenomyosis, adversely affect oocyte morphology? DESIGN: Retrospective, single-centre study evaluating 29,130 ART cycles between August 2011 and March 2023. Patients diagnosed wi…

Are there associations between clinical and embryological factors with pregnancy loss following transfer of a single euploid embryo?
Reproduction & fertility ·doi:10.1530/raf-24-0002

First trimester pregnancy losses are commonly attributed to chromosomal abnormalities. The causes of pregnancy loss following transfer of a euploid embryo are not fully elucidated. The aim of this study was to evaluate clinical and embryolo…

Prediction of risk factors for first trimester pregnancy loss in frozen-thawed good-quality embryo transfer cycles using machine learning algorithms
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-022-02645-3

PURPOSE: Can the risk factors that cause first trimester pregnancy loss in good-quality frozen-thawed embryo transfer (FET) cycles be predicted using machine learning algorithms? METHODS: This is a retrospective cohort study conducted at S…

Comparison between cycles of the same patients when using recombinant luteinizing hormone + recombinant follicle stimulating hormone (rFSH), human menopausal gonadotropin + rFSH and rFSH only.
Archives of medical science : AMS ·doi:10.5114/aoms.2017.72408

IntroductionRecombinant follicle stimulating hormone (rFSH), recombinant luteinizing hormone (rLH), and urinary human menopausal gonadotropin (uHMG) are widely used for controlled ovarian stimulation (COS). This study compares the effects o…

Transdermal versus oral estrogen: clinical outcomes in patients undergoing frozen-thawed single blastocyst transfer cycles without GnRHa suppression, a prospective randomized clinical trial.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-018-1380-5

PurposeTo conduct a non-inferiority study to compare the clinical outcomes of transdermal estrogen patch and oral estrogen in patients undergoing frozen-thawed single blastocyst transfer non-donor cycles without GnRHagonist (GnRHa) suppress…

Is there a correlation between follicle size and gene expression in cumulus cells and is gene expression an indicator of embryo development?
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-018-0388-0

BackgroundIn an article published in 2017, we discussed the results of the first part of our study into the morphokinetic development of embryos in relation to follicle diameter and homogeneity of follicular development. Our findings showed…

The effect of follicle size and homogeneity of follicular development on the morphokinetics of human embryos.
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-017-0935-1

PurposeOur aim was to investigate follicular size (large, ≥17 mm and small, <17 mm) at the time of OPU and homogeneity of follicular development (homogenous development: follicles being present in a homogenous spread of all sizes; heterogen…

In vitro fertilization in normoresponder patients with endometriomas: comparison with basal simple ovarian cysts
Gynecologic and obstetric investigation ·doi:10.1159/000112310

OBJECTIVE: To investigate whether the space-occupying effect of an endometrioma, rather than endometriosis itself, affects results in in vitro fertilization (IVF) using women with simple ovarian cysts as the control group. METHODS: 85 norm…
