AIM To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD)...
Background: It is established that sperm DNA integrity is essential in fertilization and normal embryo and fetal development.

OBJECTIVE To establish cutoff value, sensitivity, specificity and intra- and interobserver variability of total antioxidant capacity (TAC) in seminal plasma from healthy donors (controls) and infertile patients. DESIGN Seminal plasma from proven fertile donors (n = 55), nonproven fertile donors (n = 45), and infertile patients (n = 42) were examined for TAC level. SETTING Reproductive resea...
Background: Telomeres are evolutionary, specialized terminal structures at the ends of eukaryotic chromosomes containing TTAGGG repeats in human. Several human diseases have been known to be associated with dramatic changes in telomere length. The aim of the present study was to assess the correlation between the relative leukocyte telomere length (LTL) and infertility in a group of Iranian azo...
Abstract Background & Aims of the Study: According to the high prevalence of mental problems of infertility in infertile women, and the necessity of identifying their mental statuses to carry out interventions in order to help them, the present study aims a comparative study of psychological well-being, meta-emotion, and resiliency in fertile and infertile women. Materials & Methods: This study...
