O-7: Y Chromosome Microdeletions Are Not Associated with Spontaneous Recurrent Pregnancy Loss in A Sinhalese Population in Sri Lanka
Authors
Abstract:
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 pregnancy loss occurs in infertile couples. The current study was designed to examine whether Y chromosome microdeletions were associated with RPL in a Sinhalese population in Sri Lanka. Materials and Methods: The subjects were 76 male partners of couples where the female partner had experienced three or more recurrent pregnancy losses. 120 random males from the general population were also analysed as a control group. DNA extracted from peripheral blood was tested for Y chromosome microdeletions in the AZFa, AZFb, AZFc regions using a multiplex PCR amplification system. Partial deletions within the AZFc region were also tested. Results: None of the men (76 with RPL, and the 120 controls) had any microdeletions in the AZFa, AZFb, AZFc regions or partial deletions within the AZFc region. Conclusion: Y chromosome microdeletions do not appear to be important in the aetiology of RPL in this population in Sri Lanka.

Y chromosome microdeletions are not associated with spontaneous recurrent pregnancy loss in a Sinhalese population in Sri Lanka.
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 ∼7% of men with low sperm counts and, compared with the general population, a higher frequency of spontaneous pregnancy ...

STUDY QUESTION Are Y-chromosome microdeletions associated with SHOX haploinsufficiency, thus representing a risk of skeletal anomalies for the carriers and their male descendents? SUMMARY ANSWER The present study shows that SHOX haploinsufficiency is unlikely to be associated with Y-chromosome microdeletions. WHAT IS KNOWN ALREADY Y-chromosome microdeletions are not commonly known as a majo...

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 ...

This study was conducted in order to investigate the association between the single nucleotide polymorphism (SNP) rs2305957 G/A and recurrent pregnancy loss (RPL) in a group of Palestinian women residing in Gaza strip. A retrospective case-control study was carried out during the period of May to August 2015. A total of 380 females including 190 recurrent pregnancy loss (RPL) patients and 190 c...

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...
