:Y-Chromosome Microdeletion Analysis in Infertile Men from Upper Egypt.
Objectives: To study the prevalence and patterns ofY-chromosome microdeletions in infertile men from Upper Egypt and to determine the relationship between Y-chromosome microdeletions with clinical and laboratory findings in these patients. Design: Cross-sectional study. Patients: Infertile men (n = 210) and a control group of fertile men with normal semen analysis (n = 30). Methods: Clinical evaluation, standard semen analysis ...
