The Association between Y Chromosome Microdeletion and Recurrent Pregnancy Loss

چکیده
BACKGROUND To date, the role of male factor contributing in evaluation of spontaneous recurrent pregnancy loss (RPL) has been less investigated and there is discrepancy in the role of Y chromosome microdeltions in RPL. Therefore, the current study was designed to examine whether Y chromosome microdeletions were associated with RPL in an Iranian population. METHODS One hundred men from couples, experiencing three or more RPLs, and one hundred normal men from couples with at least one child and no history of miscarriages as control group were included. Genomic DNA was extracted from peripheral blood and tested for Y chromosome microdeletions in AZFa, AZFb and AZFc regions using two multiplex PCR. RESULTS None of the men in the case and control groups had any microdeletions in the AZFa, AZFb and AZFc regions. CONCLUSION It seems that Y chromosome microdeletion is not associated with recurrent pregnancy loss, therefore performing this test in Iranian couples with RPL is not recommended.

Objective Approximately 15 percent of couples are infertile. The male factor is responsible for approximately 50% of the cases. One of the main genetic factors playing a role in male infertility is Y chromosomal microdeletion within the proximal long arm of the Y chromosome (Yq11), named azoospermia factor (AZF) region. Recent studies have also demonstrated that there is a potential connection ...

Background: Many advances have been made in reproductive medicine yet the spontaneous loss of a pregnancy remains the most common complication of pregnancy. The aetiology of spontaneous recurrent pregnancy loss (RPL) is multifactorial. Y chromosome microdeletions are found in approximately 7% of men with low sperm counts and, compared to the general population, a higher frequency of spontaneous...

Background: The Y chromosome microdeletion is one of the best-documented causes of male infertility but the factors responsible for Y chromosome microdeletions in spermatozoa remain unresolved. However, the environmental pollutants are known to damage DNA in differentiating and maturing germ cells in the male reproductive tract. In view of this, the objective of the present study was to explore...

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 couple...
