Aneuploidy Assessment of X, Y, 18 Chromosomes in Sperm of Oligoteratospermia Using FISH Technique

Introduction: Not being to get pregnant, after one year of unprotected sex is called infertility. In the post, infertility was mainly a female problem, but the role of male factors in infertility has denotation, although a greater percentage of this infertility is related to the deficiencies of semen. Methods: This case-control study was performed on sperm samples from 30 infertile oligoteratozoospermia (OT) patients as case group and 30 fertile and normosperm as controls, all the patients and controls between the ages of 20-49 years, who were referred to the Yazd Infertility Center for the treatment of infertility, were used to check the chromosomes 18, X and Y using the FISH technique. The results were considered using SPSS version 16 software and statistical tests T-TEST and Chi-Square Tests for statistical analysis and Pearson R correlation coefficient to measure the relationship between variables and statistical level P <0.05. Results: Disorders were observed in infertile oligoteratozoospermia men who were significantly related to the control group and between the chromosomal abnormalities, sperm counts and morphology )P<0/01) and there was also significant difference in correlation between chromosomal abnormalities and duration of infertility  (P<0/01). In addition, there was no correlation between chromosomal abnormalities and age, but the rate of chromosomal abnormalities in the age group of 40-49 years increased to 50%, which has the highest rate among age groups and definitely needs to be examined in a larger statistical population. Conclusion: This finding suggest that patients with OT may be at an increased risk of producing aneuploid offspring. Considering the chromosomal aneuploidy is recommended by cytogenetic molecular techniques.
