Sperm Dna Quality Predicts Intrauterine Insemination Outcome: A Prospective Cohort Study, Eyup Duran, M. Morshedi, S. Taylor, S. Oehninger

BACKGROUND: We aimed to investigate whether sperm DNA quality may predict intrauterine insemination (IUI) outcome. METHODS: The study was designed in a prospective cohort fashion, at a tertiary centre for reproductive medicine. A total of 119 patients underwent 154 cycles of IUI. Parameters related to demography, cycle management and semen sample used for IUI were evaluated. Conventional semen parameters, morphology (strict criteria), sperm DNA fragmentation and stability [evaluated by terminal deoxynucleotidyl transferase-mediated dUDP nick-end labelling (TUNEL) and acridine orange staining under both acid and acid + heat denaturing conditions respectively] were measured. The main outcome measure was clinical pregnancy, defined …

OBJECTIVE: To evaluate the impact of age on the expression of apoptotic biomarkers in human spermatozoa. DESIGN: Cross sectional, prospective study. SETTING: Academic centers. PATIENT(S): Healthy volunteers with proven fertility, stratified by age (n = 25, range: 20-68 years). INTERVENTION(S): Examination of serum hormone levels and basic semen parameters, and assessment of early (plasma membrane translocation of phosphatidylserine) and late (DNA fragmentation) sperm apoptotic markers by flow cytometry (using Annexin-V binding and terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling). MAIN OUTCOME MEASURE(S): Apoptosis markers. RESULT(S): Advancing male age was significantly and positively correlated with Annexin-V binding results. Although not significant, …
