Y- Kromozom Mikrodelesyonları ve Tekrarlayan Gebelik Kayıpları  Dewan and colleagues conducted a study which demonstrated that the prevalence of y-chromosome microdeletions was higher in patients(couples) undergoing evaluation for recurrent pregnancy loss (n=17) compared to 18 fertile couples without pregnancy loss and 10 infertile men.

Eighty-two (82%) percent of the men from the couples with recurrent pregnancy loss as compared to 0% in the normally fertile males and 20% in the infertile males were found to have microdeletions in the AZFc region of the Y chromosome
