Abstract
OBJECTIVES
We aimed to assess seminal calbindin 2 (CALB 2) expression in men with different semen parameters as well as its correlation with reproductive hormones in azoospermic patients and different semen parameters in oligoasthenoteratozoospermic patients. CALB 2 is also known as calretinin and 29 kDa calbindin.
MATERIALS AND METHODS
This prospective study was performed on 96 cases from the andrology outpatient clinic divided into 3 groups as follows: group 1 including 32 non obstructive azoospermic (NOA) patients, group 2 including 32 patients with oligoasthenoteratozoospermia (OAT), and Group 3 including normozoospermic individuals as controls. Semen analysis and estimation of seminal CALB 2 concentrations by enzyme linked immunosorbent assay (ELISA) technique were performed for all participants. Reproductive hormones were measured in nonobstructive NOA patients.
RESULTS
The mean seminal CALB 2 level was higher in OAT patients compared to NOA patients and controls (7.8 ± 1.30 ng/ml, 7.3 ± 0.80 and 7.4 ± 1.0, respectively). Furthermore, the study had shown strong positive correlations between CALB 2 and sperm normal forms in controls and OAT patients. In contrast, there was no significant correlation between seminal CALB 2 and any of the reproductive hormones measured in NOA patients.
CONCLUSIONS
Seminal CALB 2 may play a role in increasing the abnormal forms in OAT patients.
