Controlled ovarian stimulation (COS) with follitropin delta results in higher cumulative live birth rates compared with follitropin alfa/beta in a large retrospectively analyzed real-world data set
Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-025-01364-5

BACKGROUND: Follitropin delta (hrFSH) is the first recombinant follicle-stimulating hormone produced in a human cell line and more closely resembles native human FSH than follitropin alfa/beta (rFSH). Its efficacy and safety have been demon…

GRN, NOTCH3, FN1, and PINK1 expression in eutopic endometrium - potential biomarkers in the detection of endometriosis - a pilot study
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-020-01905-4

PURPOSE: Endometriosis (EM) is a common gynecological disease affecting 10-15% of women of reproductive age. However, molecular mechanisms and pathogenesis are still not completely understood. Furthermore, due to the absence of a reliable c…

Intraindividual Embryo Morphokinetics Are Not Affected by a Switch of the Ovarian Stimulation Protocol Between GnRH Agonist vs. Antagonist Regimens in Consecutive Cycles
Frontiers in endocrinology ·doi:10.3389/fendo.2020.00246

Background: The impact of controlled ovarian stimulation (COS) during medically assisted reproduction (MAR) on human embryogenesis is still unclear. Therefore, we investigated if early embryonic development is affected by the type of gonado…

Relative Morphokinetics Assessed by Time-Lapse Imaging Are Altered in Embryos From Patients With Endometriosis
Reproductive sciences (Thousand Oaks, Calif.) ·doi:10.1177/1933719117741373

INTRODUCTION: Time-lapse technology allows almost continuous noninvasive assessment of embryonic development. It was shown previously that relative kinetics defining cleavage synchronicity are better predictors of blastocyst quality than ab…
