Effect of Thiol-Disulfide Homeostasis and Ischemia-Modified Albumin Levels on IVF Results in Male Factor Infertility

Overview

Thiol-disulfide Homeostasis (TDH) is essential for physiological functions in the human reproductive system, including antioxidant defense, detoxification, signal transduction, enzymatic regulation, apoptosis, and cellular communication. Ischemia-Modified Albumin (IMA) serves as an indicator of oxidative stress (OS) and is linked to ischemia-reperfusion injury. This study aimed to investigate changes in OS markers, particularly TDH and IMA levels, in couples with male infertility, and to examine the relationship between these markers and in vitro fertilization (IVF) success. Understanding how TDH and IMA levels influence IVF outcomes is crucial for advancing reproductive treatments for couples having diagnosis of infertility.

The thiol-disulfide Homeostasis (TDH) is believed to participate in critical physiological functions, including antioxidant defense, detoxification, signal transduction, enzymatic activity regulation, apoptosis, and cellular communication within the human reproductive system. Ischemia-Modified Albumin (IMA) is considered a surrogate marker for oxidative stress (OS) and has also been linked to ischemia-reperfusion injury. The present study was designed to investigate the alteration of OS markers, including TDH and IMA levels, in couples diagnosed with male infertility, and to examine the association between these OS markers and in vitro fertilization (IVF) success. Couples in which women aged 23-45 years and undergoing IVF treatment due to male factor and unexplained infertility will be enrolled. The serum native thiol (NT), total thiol (TT) levels, disulfide levels and disulfide/TT and NT/TT ratios will be compered between two groups. The serum ischemia-modified albumin (IMA) level will also compared between male infertility and unexplained infetility group. TDH related parameters as NT and TT may be useful as a reflection of OS and as potential diagnostic biomarkers for male infertility
