Oxidative homeostasis in follicular fluid and reproductive outcomes – from bench to bedside

2022

Free radicals and oxidant molecules are part of our organism in a stable balance. However, when addressing female infertility, questions about their role in oocyte quality arise. This review outlines the major alterations of redox homeostasis in the follicular fluid through pathophysiological conditions in female reproduction and its potential effect on IVF outcome. A review of the literature was accurately performed. Manuscripts investigating follicular fluid biomarkers, especially related to oxidant molecules, were screened and used in this review. Studies assessing the follicular reactive species were found and screened. Moreover, studies assessing the IVF outcomes related to biomarkers …

Impact of Endocrine Disorders on IVF Outcomes: Results from a Large, Single-Centre, Prospective Study

2022

Abstract Endocrine disorders negatively influence the ovarian function, and increasing incidence of endocrine diseases with age may have further negative effects on pregnancy rate. Prospective cohort study of 231 consecutively enrolled patients underwent IVF treatment. In patients with known endocrine disorders, the laboratory parameters were corrected before IVF treatment. One hundred sixty one patients (69.7%) had at least one known and treated endocrine disorder (study group), and 70 patients were endocrine negative (control group). Endocrine disorders diagnosed were thyroid disorders (32.5%), diminished ovarian reserve (23.8%), insulin resistance (22.5%), PCOS (15.2%), hyperprolactinaem…

Effect of thyroid function on assisted reproduction outcomes in euthyroid infertile women: A single center retrospective data analysis and a systemat…

2022

BackgroundThe influence of thyroid-stimulating hormone (TSH) on gestational outcomes have been studied and checked whether differing TSH levels are relevant on human reproduction outcomes. International guidelines recommend TSH values <2.5 mIU/L in women trying to conceive, since values above this level are related to a higher frequency of adverse reproductive outcomes. This study aimed to evaluate whether TSH values correlate with different gestational outcomes in euthyroid infertile women without autoimmune thyroid disease.MethodsA retrospective cohort study was conducted involving 256 women who underwent in vitro fertilization (IVF) treatment. The participants were divided into tw…

Impact of FIGO type 3 uterine fibroids on in vitro fertilization outcomes: A systematic review and meta‐analysis

2023

Background: The effect of FIGO (the International Federation of Gynecology & Obstetrics) type 3 myomas on in vitro fertilization (IVF) is uncertain. Objectives: To evaluate whether FIGO type 3 myomas affect IVF outcomes, through a systematic review and meta-analysis (CRD42022379700). Search strategy: Electronic databases were searched until November 15, 2022. Selection criteria: Studies evaluating the effects of FIGO type 3 myomas on IVF outcome. Data collection and analysis: Pooled results were expressed as odds ratios (OR) with 95% confidence intervals (CI). Heterogeneity was assessed using Higgins I2 . Sources of heterogeneity were explored with sensitivity and subgroup analyses. Mai…

Cuantificación de la calidad embrionaria mediante el consumo de oxígeno durante el proceso rutinario de incubación y desarrollo in vitro

2015

A pesar de la aplicación intensiva de las TRA y de las cada vez mayores tasas de éxito, hay ciertos aspectos de estos tratamientos que continúan sin resolverse, siendo una limitación importante el hecho de que sólo entre el 10-20% de los embriones transferidos al útero sean capaces de dar lugar a un embarazo a término. Esta limitación está promoviendo el desarrollo de nuevas técnicas no invasivas para seleccionar embriones más eficazmente que mediante el mero criterio morfológico. Las evidencias apoyadas por distintos trabajos encontrados en la literatura hacen que consideremos algunos métodos no invasivos, como la actividad metabólica de ovocitos y embriones, como buenos predictores de la …

Anxiety and depressive symptoms, and stress biomarkers in pregnant women after in vitro fertilization: a prospective cohort study.

2017

STUDY QUESTION Does in vitro fertilization (IVF) affect the course of anxiety and depressive symptoms as well as physiological stress from pregnancy to postpartum period? SUMMARY ANSWER IVF mothers have more anxiety symptoms and higher stress biomarker levels but fewer depression symptoms than natural conception mothers at the third trimester of pregnancy, but these differences are negligible during postpartum period. WHAT IS KNOWN ALREADY Cross-sectional studies have found an association between IVF and high stress levels during the prenatal period. There is, however, no follow-up study about the IVF effect on the mental health status from pregnancy to postpartum, adopting simultaneous mea…
