Endometrial Metabolism of 17β-Estradiol during the Window of Implantation in Women with Recurrent Implantation Failure.
Gynecologic and obstetric investigation ·doi:10.1159/000546442

Objectives: Alterations in 17β-estradiol metabolism are known to potentially impair endometrial receptivity. Previous pioneering studies have investigated the role of endometrial steroid metabolism by determining steroid hormone levels and …

Journal of assisted reproduction and genetics ·doi:10.1007/s10815-024-03257-9

PurposeThe goal of this study was to determine ongoing pregnancy rate, time to pregnancy and embryo transfers to pregnancy within a cohort of patients with recurrent implantation failure (RIF).MethodsIVF patients with RIF were included afte…

Local production of 17β-oestradiol in the endometrium during the implantation window: a pilot study.
Reproduction & fertility ·doi:10.1530/raf-23-0065

AbstractSex steroids are converted to bioactive metabolites and vice versa by endometrial steroid-metabolising enzymes. Studies indicate that alterations in this metabolism might affect endometrial receptivity. This pilot study determined w…

Endometrial factors in the implantation failure spectrum: protocol of a MUltidisciplinary observational cohort study in women with Repeated Implantation failure and recurrent Miscarriage (MURIM Study).
BMJ open ·doi:10.1136/bmjopen-2021-056714

IntroductionWomen with repeated implantation failure (RIF) and unexplained recurrent miscarriage (RM) are proposed to be at opposite ends of the implantation spectrum, with RM representing an overly receptive endometrium (implantation of ge…
