This study assessed the influence of the age of the male partner on the outcome of oocyte donation cycles. A total of 408 couples participating in 519 consecutive anonymous oocyte donation cycles were examined. Main outcome measures were fertilization rate, embryo quality, clinical pregnancy, implantation, miscarriage and live birth rates, as well as the total reproductive potential, which estimates the outcome from fresh and cryopreserved-thawed embryo transfers. A total of 241 cycles resulted in clinical pregnancy (48.5% of transfers). The mean embryo score for transferred embryos (ESTE) was higher in cycles resulting in pregnancy (P=0.003). Semen volume (P<0.001), sperm …


Sperm Dna Quality Predicts Intrauterine Insemination Outcome: A Prospective Cohort Study, Eyup Duran, M. Morshedi, S. Taylor, S. Oehninger Jun 2013

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, …


Endometrial Response To Unopposed Estrogens Remains Unaltered In Patients With Chronic Renal Failure Receiving Hemodialysis, M. Ergeneli, Eyup Duran, H. Zeyneloglu, B. Demirhan, M. Erdogan Jun 2013

Endometrial Response To Unopposed Estrogens Remains Unaltered In Patients With Chronic Renal Failure Receiving Hemodialysis, M. Ergeneli, Eyup Duran, H. Zeyneloglu, B. Demirhan, M. Erdogan

Most patients with chronic renal failure who are on maintenance hemodialysis are anovulatory and have menstrual abnormalities. This study was designed to determine the prevalence of organic causes of abnormal uterine bleeding in this group of patients exposed to unopposed estrogens. Eighteen patients with chronic renal failure and abnormal uterine bleeding underwent vacuum curettage. The histopathologic findings were compared with a group of 154 premenopausal women who had abnormal uterine bleeding without detectable organic causes. Excluding patients with secretory and atrophic endometrium, only 2 of 8 patients (25%) with chronic renal failure had endometrial lesions while 44 of 131 patients …
