Cognitive, emotional, communicative, and motor development in children born from couple's gametes cryopreserved oocytes. A 20 years single-center experience.

Objective: To study if social and emotional, communicative, cognitive, motor development of children born from cryopreserved oocytes are comparable to general population.

Design: Survey study.

Exposure: This is a single-center population study, focusing on all children born from cycles of in vitro fertilization of cryopreserved oocytes at Humanitas Fertility Center from January 1st,2003, until December 31st, 2021.

Steps forward in embryo transfer technique: a retrospective study comparing direct versus afterload catheters at different time frames.

Purpose: To assess whether embryo transfer (ET) technique can influence the clinical pregnancy rate (CPR) and its correlation with the embryo transfer difficulty.

Design: This single center retrospective cohort analysis of fresh and frozen single blastocyst transfers performed between January 2016 and December 2021 included fresh and frozen single blastocyst transfers performed during the study timeframe. Direct technique was the only one used from January 2016 to September 2017.

A Monocentric Randomized Controlled Clinical Trial to Compare Single- and Double-Lumen Needles in Oocyte Retrieval Procedure in Assisted Reproductive Technologies.

The purpose was to determine any difference in outcomes, primarily in terms of number of retrieved oocytes per procedure, between two different needles used for oocytes retrieval procedure in Assisted Reproductive Technologies: the single-lumen needle (SLN) versus the double-lumen needle (DLN) with follicle flushing after aspiration. This randomized controlled trial included oocyte retrieval (OR) cycles for IVF and ICSI performed in 18 to 42-year-old women between March 2019 and January 2021 at a tertiary-care Fertility Center. A total of 200 ORs were randomized, 100 in each group.

Why are they not coming back? A single-center follow-up study on oncological women oocyte's storing for fertility preservation.

Introduction: Oocyte cryopreservation is a valid option for female cancer patients to preserve fertility. The number of patients undergoing fertility preservation (FP) cycles has increased over the past years. Nevertheless, the rates of patients returning to use their cryopreserved material have shown to be considerably low, ranging from 5-8%, but significant data regarding the reasons of such low return rates are scarce.

Oxidative Stress and Human Ovarian Response-From Somatic Ovarian Cells to Oocytes Damage: A Clinical Comprehensive Narrative Review.

Basic scientific research on human reproduction and oxidative damage has been extensively performed; however, a more clinical view is still lacking. As a result, exhaustive data on the influence of oxidative stress on human ovarian response and, consequently, on fertility are still lacking. This narrative review aims at summarizing the role of oxidative stress in different conditions associated to female infertility and to list some of the main antioxidant agents.
