ABSTRACT

OBJECTIVES:

The aim of this study was to evaluate polymorphisms of sperm protamine genes and their effects on the result of CMA3 staining in varicocele men. MATERIAL AND

METHODS:

In a case control study, 128 patients with male infertility due to varicocele and 128 controls were recruited. Polymorphisms of PRM1 and PRM2 genes in extracted DNA samples were assessed by PCR-SSCP and sequencing. Protamine deficiency was also indirectly estimated by CMA3 staining.

RESULT:

Nine different variants including six variants in PRM1 gene and three variants in PRM2 gene were found among varicocele patients. The results showed that sperm count, motility and morphology were significantly different between control group without gene variations and varicocele group who had several variations in their protamine genes (P<0.05).

CONCLUSION:

Therefore, PRM1 and PRM2 variations in varicocele patients are associated with the production of spermatozoa with more protamine deficiency and this is one of the possible causes of infertility due to varicocele
RESUMEN

OBJETIVOS:

El objetivo de este estudio fue evaluar los polimorfismos de los genes de la protamina espermática y sus efectos sobre el resultado de la tinción CMA3 en varones con varicocele. MATERIAL Y

MÉTODOS:

En un estudio de casos y controles, se reclutó a 128 varones con infertilidad por varicocele y 128 controles. Los polimorfismos de los genes PRM1 y PRM2 en muestras de ADN extraídas se evaluaron mediante PCR-SSCP y se realizó su secuenciación. La deficiencia de protamina también se estimó indirectamente mediante tinción CMA3.

RESULTADO:

Se encontraron 9 variantes diferentes, incluidas 6 variantes en el gen PRM1 y 3 variantes en el gen PRM2 entre los pacientes con varicocele. Los resultados mostraron que el recuento de espermatozoides, la movilidad y la morfología eran considerablemente diferentes entre el grupo de control sin variaciones genéticas y el grupo de varicocele que presentaba algunas variaciones en sus genes de protamina (p < 0,05).

CONCLUSIÓN:

Por tanto, las variaciones de PRM1 y PRM2 en los pacientes con varicocele están asociadas con la producción de espermatozoides con más deficiencia de protamina y esta es una de las posibles causas de infertilidad debida al varicocele
