The objectives of this study were to determine if human ejaculated sperm exhibit active caspases and if caspase-dependent apoptosis markers are identifiable. Sperm from fertile donors and infertile patients were examined after gradient separation into leukocyte-free fractions of high and low motility. Sperm were evaluated for motion parameters, morphology,(More)
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(More)
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 IVF programme were prospectively investigated. Semen samples from 66 men were evaluated by routine semen analysis, morphology evaluation(More)
OBJECTIVE To evaluate a prospectively implemented clinical algorithm for early identification of ectopic pregnancy (EP) and heterotopic pregnancy (HP) after assisted reproductive technology (ART). DESIGN Analysis of prospectively collected data. SETTING Academic medical center. PATIENT(S) All ART-conceived pregnancies between January 1995 and June(More)
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(More)
OBJECTIVE To assess the significance of atypical squamous cells of undetermined significance (ASCUS) in predicting the presence of underlying squamous intraepithelial lesion (SIL) of the uterine cervix, and to determine the best follow-up method for these patients. STUDY DESIGN We reviewed 76 cases with cervical smears that had been labeled ASCUS over a(More)
In this study we extended earlier work to determine whether sperm respond to somatic cell apoptotic stimuli and whether apoptotic phenotypes are significant indicators of human sperm quality. We evaluated ejaculated sperm from fertile donors and subfertile patients following purification of fractions of high and low motility. In unstimulated conditions,(More)
The objective of this study was to assess the temporal effects of sperm incubation at body temperature with various amounts of human serum albumin (HSA) on motion parameters and phosphatidylserine externalization, an expression of membrane integrity. Purified sperm populations were prepared by discontinuous gradient separation, incubated at 37 degrees C in(More)
OBJECTIVE Reassignment surgery of the female-to-male transsexual is a rarely performed surgical procedure that should involve a gynecologist's consultation and expertise. This study examines the experience with this type of surgery at Baskent University Hospital, Ankara, Turkey, from the gynecologists' point of view. STUDY DESIGN Eight patients underwent(More)
OBJECTIVE To determine the effect of elective single ET (eSET) on live birth and multiple birth rates by a cycle-level and clinic-level analysis. DESIGN Retrospective cohort study. SETTING Not applicable. PATIENT(S) Patient ages <35 and 35-37 years old. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Clinics were divided into groups based on eSET(More)
