A COMPARATIVE STUDY BETWEEN EMBRYO QUALITY FERTILIZED WITH NORMAL EJACULATE SPERMS VS. TESA/PESA SPERMS

Abstract

Our study aims to compare the quality of embryos fertilized using sperm obtained from testicular sperm aspiration (TESA) or percutaneous epididymal sperm aspiration (PESA) against those sourced from normal ejaculate in the intracytoplasmic sperm injection (ICSI). Male infertility is a significant issue. A particularly challenging form is azoospermia, a condition in which there are no sperm in the ejaculate. Azoospermia can be obstructive (OA) or non-obstructive (NOA). The causes for azoospermia vary; they can include genetic disorders, such as cystic fibrosis, or physical blockages. For patients with azoospermia, surgical methods like TESA & PESA offer hope for biological parenthood. This study's goal is to assess how effective these methods are in embryo fertilization by observing embryos till day 5 -blastocyst stage. These blastocysts serve as an important indicator of embryo viability.
