We aimed to investigate whether sperm DNA quality may predict intrauterine insemination (IUI) outcome.The study was designed in a prospective cohort fashion, at tertiary centre for reproductive medicine. A total of 119 patients underwent 154 cycles IUI. Parameters related demography, cycle management and semen sample used IUI were evaluated. Conventional parameters, morphology (strict criteria), fragmentation stability [evaluated by terminal deoxynucleotidyl transferase-mediated dUDP...

In this study we extended earlier work to determine whether sperm respond somatic cell apoptotic stimuli and phenotypes are significant indicators of human quality. We evaluated ejaculated from fertile donors subfertile patients following purification fractions high low motility. unstimulated conditions, caspase enzymatic activity was higher in motile than donors, motility both groups. Staurosporine, but not a Fas ligand or H2O2, significantly increased activity, only fractions....

To determine predictive values of routine semen analysis, sperm morphology evaluation using strict criteria and DNA status for in-vitro fertilization (IVF), 66 consecutive couples undergoing IVF in a university hospital programme were prospectively investigated. Semen samples from men evaluated by acridine orange staining determination status. A new technique is described scoring which consisted two smears per case, with without heat treatment. Resistance to heat-provoked denaturation was...

We conducted a prospective blinded study to evaluate the costs, accuracy, risks, and benefits of 3-dimensional (3D) transvaginal sonography compared hysterosalpingography.A total 101 women aged 26 44 years with evidence uterine anomalies were enrolled. All participants had routine hysterosalpingography as part their infertility evaluation well 3D study. Surgical findings used standard for final diagnosis.A 6 normal uteri 119 classified: 30 congenital (3 arcuate, 1 unicornuate, 4 bicornuate,...

Systemic lupus erythematosus (SLE) flare is common, and renal involvement one of the most serious problems during pregnancy. Aggressive immunosuppressive therapy should be considered for patients with diffuse proliferative nephritis. These individuals are at high risk progression to end-stage disease. Immunosuppressive drugs can cause significant toxic teratogenetic effects. In this report, we describe case a pregnant patient nephritis who was treated cyclophosphamide. The in second...

ABSTRACT: The objective of this study was to assess the temporal effects sperm incubation at body temperature with various amounts human serum albumin (HSA) on motion parameters and phosphatidylserine externalization, an expression membrane integrity. Purified populations were prepared by discontinuous gradient separation, incubated 37°C in 3 different culture conditions (human tubal fluid [HTF] alone, HTF plus 0.3% HSA, 3% HSA) evaluated 0, 1, 3, 6, 24 hours. Annexin V binding used monitor...

This study investigated the role of systemic inflammation in development atrial fibrillation (AF) after coronary artery bypass grafting (CABG). CABG was performed using cardiopulmonary 77 patients. Pre-operative AF present six patients (7.8%) and postoperative developed 13 (18.3%) 71 with pre-operative sinus rhythm. Post-operative mediastinal drainage significantly increased post-operative compared those Plasma E-selectin, P-selectin vascular cell adhesion molecule levels were not different...

Pregnancy achieved with sperm from a patient globozoospermia is rare, even after ICSI, since the activation of oocyte may not occur in this disorder. Therefore, oocytes by piezoelectricity or calcium ionophores has been suggested, although spontaneous ICSI reported some cases. We report successful pregnancy couple which male partner had microdeletions Y chromosome no further assisted ICSI. During diagnostic study husband, increased numerical abnormalities fluorescent in-situ hybridization...
