Number needed to freeze: cumulative live birth rate after fertility preservation in women with endometriosis

2021

Research question: How does the number of oocytes used affect the cumulative live birth rate in endometriosis patients who had their oocytes vitrified for fertility preservation (FP)? Design: Retrospective observational study including data from 485 women with endometriosis who underwent FP from January 2007 to July 2018. Survival curves and Kaplan-Meier plots were used to analyse the cumulative live birth rate (CLBR) according to the number of vitrified oocytes used. Data were stratified according to age, stage of the disease and ovarian surgery prior to FP (operated vs. non-operated). Endometriosis curves were compared to plots developed using elective fertility preservation (EFP) patient…

Comparison of different sources of platelet-rich plasma as treatment option for infertility-causing endometrial pathologies

2020

Objective To study the effect of human plasma from different sources, namely, umbilical cord blood and adult blood platelet-rich plasma (PRP), on the regeneration of endometrial damage. Design Composition analysis, in vitro approaches, and a preclinical murine model using plasma to promote endometrial regeneration. Setting Hospital and university laboratories. Patient(s)/Animal(s) Adult plasma from four Asherman syndrome/endometrial atrophy patients and one fertile woman, commercial umbilical cord plasma, and uterine-damaged NOD/SCID mice model were used. Intervention(s) Endometrial stromal cells from primary culture and an endometrial stem cell line were cultured in vitro, and uterine-dama…

Reproductive outcomes after hysteroscopic metroplasty for women with dysmorphic uterus and recurrent implantation failure

2019

The aim of this study was to assess the reproductive outcomes of women with recurrent implantation failure (RIF) after hysteroscopic metroplasty for dysmorphic uteri. Methods: This retrospective observational study included 190 women with a diagnosis of RIF. These patients were eligible for hysteroscopic metroplasty for dysmorphic uteri, including T-shaped uteri, between January 2008 and September 2015 at the Instituto Valenciano de Infertilidad (IVI) in Valencia, Spain. Results: The total clinical pregnancy rate, the live birth rate, and the abortion rate were 80.0% (152/190), 77.9% (147/190) and 8.9%, respectively. At 12 months, the clinical pregnancy rate was 76.3% (145/190) and at 6 mon…

Efectos de la alteración endocrina durante la gestación: una revisión sistemática

2014

Los alteradores endocrinos son contaminantes ambientales, naturales y sintéticos, ubicuos, que pueden mimetizar, bloquear o alterar funciones hormonales. La exposición ambiental a estos contaminantes es prácticamente imposible de evitar debido a que están presentes en el aire, en el agua, en los suelos, en los alimentos, y en muchos de los materiales con los que estamos en contacto diariamente, como los plásticos. La gestación supone una etapa de vulnerabilidad para el feto porque su organismo está en proceso de desarrollo y cualquier alteración puede afectar su salud a corto o largo plazo. Hay cierta evidencia de que estas sustancias alteran procesos de crecimiento y diferenciación de teji…

Copyright © 2022 by the authors. Background: International organizations recommend initiating breastfeeding within the first hour of life and maintaining exclusive breastfeeding for the first 6 months. However, worldwide rates of exclusive breastfeeding for 6-month-old infants is far from meeting the goal proposed by the World Health Organization, which is to reach a minimum of 50% of infants. Education is one of the factors affecting the initiation and continuation of breastfeeding, and incidentall…

The influence of oxygen concentration during embryo culture on obstetric and neonatal outcomes: a secondary analysis of a randomized controlled trial.

2020

Abstract STUDY QUESTION Does oxygen concentration during 3-day embryo culture affect obstetric and neonatal outcomes? SUMMARY ANSWER Oxygen concentration during 3-day embryo culture does not seem to affect the obstetric and neonatal outcomes measured. WHAT IS KNOWN ALREADY Atmospheric oxygen appears to be harmful during extended embryo culture. Embryo culture conditions might therefore be a potential risk factor for subsequent fetal development and the health of future children. No data are available concerning the obstetrics and neonatal outcomes after Day 3 transfer of embryos cultured under reduced and atmospheric oxygen tensions. STUDY DESIGN, SIZE, DURATION A secondary analysis of a pr…

Analysis of Caesarean Section Rates Using the Robson Classification System at a University Hospital in Spain

2020

Background: The WHO recommends the use of the Robson ten-group classification system (RTGCS) as an effective monitoring and analysis tool to assess the use of caesarean sections (CS). The present study aimed to conduct an analysis of births using the RTGCS in La Ribera University Hospital over nine years and to assess the levels and trends of CS births. Methods: Retrospective study between January 1, 2010, and December 31, 2018. All eligible women were allocated in RTGCS to determine the absolute and relative contribution made by each group to the overall CS rate
