OBJECTIVE To study the methylation imprinting marks of two oppositely imprinted genes, H19 and MEST/PEG1, in human testicular spermatozoa from azoospermic patients with different etiologies. Testicular spermatozoa are often used in intracytoplasmic sperm injection for treatment of male factor infertility, but the imprinting status of these cells is currently unknown. DESIGN Experimental prospective study. SETTING University research laboratory and private in vitro fertilization (IVF) clinic… CONTINUE READING
