Oocyte Competence

This study aims to assess the effect of age of the male partner and the reproductive ability of sperm prepared via sperm selection devices (Zymot) compared to routine embryologist selected sperm after density gradient centrifugation (DGC) preparation for intracytoplasmic sperm injection (ICSI) in patients undergoing in vitro fertilization treatment (IVF) of their infertility.

The purpose of this study is to investigate the potential of autologous adipose stem cell (ASC) mitochondrial transfer (ASCENT) to oocytes along with intracytoplasmic sperm injection (ICSI)as a means of enhancing embryo development and improving the success rate of in patients with a history of multiple IVF failures. Embryo quality plays a crucial role in determining the success of assisted reproductive technologies and directly contributes to repeated pregnancy failures. Several factors, including age, physiological conditions, genetics, and environmental influences, can significantly impact embryo quality. Oocytes, the largest cells in the human body, are heavily reliant on mitochondria. Mitochondria's role in providing energy for oocytes is crucial, and insufficient energy production has been linked to poor oocyte and embryo quality. Some human studies have shown that increasing oocyte mitochondrial mass can improve embryo quality in patients who have experienced repeated IVF failures.
