Study participants consisted of 160 individuals diagnosed a...
Varicocele-associated male infertility has classically been managed using surgery or assisted reproductive techniques. With increasing evidence of oxidative stress as a pathophysiological factor in varicocele-associated infertility, medical therapy especially antioxidants might become a treatment option with lower risks. We reviewed the existing literature on the role of various medical agents ...
background: objective: the aim of our study was to assess the effect of storage duration of frozen embryo on art outcome. materials and methods: in this retrospective study the data of 651 frozen-thawed embryo transfer cycles were assessed over a 36-months period. our patients were categorized according to storage time of freeze. group i: less than 90 days, group ii: between 90-365 days. gr...
objective: this study aimed to evaluate the effect of seasonal variability on the assisted reproductive technique (art) success rate. materials and methods: this study was a descriptive – analytical survey performed on 91 infertile women undergoing intracytoplasmic sperm injection – embryo transfer (icsi-et) in different seasons. the patients aged less than 35 years old and had normal lh/fsh r...
Heterotopic pregnancy (HP) is a rare entity occurring in 1:30000 pregnancies but its incidence raises as a result of assisted reproductive techniques (ART) to 1:100-1:500. The aim of this report was to present a rare case of simultaneous intrauterine and extrauterine tubal pregnancy in a natural conception cycle. The ectopic pregnancy was not diagnosed in the first trimester scan and at 14 and ...
Assisted reproductive techniques (ART) have now been extensively incorporated in the management of infertile couples. But even after rapid methodological and technological advances the success rates of these procedures have been below expectations. This has led to development of many sperm preparation protocols to obtain an ideal semen sample for artificial reproduction. Sperm apoptosis has bee...
UNLABELLED Objective : There is an increasing rate of ectopic pregnancy with the use of assisted reproductive techniques. There is currently no serum test to differentiate ectopic pregnancy from miscarriage. Early and accurate detection of ectopic pregnancy may prevent the development of complications. The aim of this study was whether the ratio of serum/curettage material hCG could provide us ...
BACKGROUND Knowledge about assisted reproductive techniques (ART) and its procedures affect the attitude of infertile people. Making decisions about the use of ART is affected by one's perception and attitude. OBJECTIVE The aim of this cross-sectional study was to determine the attitude of infertile couples toward applying ART, and to investigate its related factors. MATERIALS AND METHODS A...

The sperm parameters concentration, motility and morphology are, however, claimed to be poor predictors of a male ́s fertility status, this in natural conception (Bonde et al., 1998; Guzick et al., 2001) as well as in assisted reproductive techniques (ART) (...
