Background: Recurrent pregnancy loss is a form of infertility with at least three consecutive pregnancy losses or more. Y chromosome microdeletions are a class of most likely genetic factors that occur in a special zone of Y chromosome which is named azoospermia factor region. The purpose of this study was to analyze the presence of Y chromosome complete microdeletions in male partner of couples suffering from idiopathic recurrent pregnancy loss among Iranian population.
Methods: In the present study, Y chromosome microdeletions were evaluated in ninety-two male partners of couples with the experience of recurrent pregnancy loss as the patient group and also a group containing fifty fertile males as the control group. The research has done in Medical Genetic laboratory of Tehran and Islamic Azad University Science and Research Branch, Tehran, Iran within June 2013 to September 2014. The selected sequence tagged site markers (primers) including sY84, sY86, for azoospermia factor a; sY127, sY134, sY129, for azoospermia factor b and sY254, sY255, for azoospermia factor c were used to screen complete microdeletions in Y chromosome. At the first step DNA samples were extracted from all men’s peripheral blood in both patient and control groups and then multiplex polymerase chain reaction and also agarose gel electrophoresis were performed on this DNA samples so as to detect deletions.
Results: With due attention to the data resulted from multiplex polymerase chain reaction and agarose gel electrophoresis in order to recognize Y chromosome micro deletions in azoospermia factor region, in this work, all the bands related to the mentioned primers which were formed during the polymerase chain reaction, were detected on the gel obviously. It means that none of the samples neither the fifty fertile men nor the ninety-two patient men had complete micro deletions in their Y chromosome.
Conclusion: This study suggests that there is no correlation between Y chromosome micro deletions and occurrence of recurrent pregnancy loss in Iranian population.
