The aetiology of azoospermia can be grossly divided into obstructive and non-obstructive causes. Although in both cases testicular spermatozoa can be used to treat male fertility, it is not well established whether success rates following intracytoplasmic sperm injection (ICSI) are comparable. Therefore, a retrospective analysis of fertilization, pregnancy and embryo implantation rates was perf...

BACKGROUND The aim of this study was to compare pregnancy rates in patients undergoing IVF/ICSI with embryo transfer after 4 and 5 days of culture in a closed incubation system with integrated time-lapse imaging. METHODS Out of n = 2207 in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) cycles performed between January 2011 and April 2016 at a tertiary referral university h...

background: embryo transfer has received little clinical attention and has been the most inefficient step in in-vitro fertilization (ivf). recent reports have suggested that an awareness of the position and length of the uterus during embryo transfer might be helpful in improving pregnancy rate. objectives: the main objective of the present study was to determine the relation between the length...

Cumulative pregnancy rate has been significantly increased since frozen-thawed embryo transfer was applied in ART cycles. This method has become an essential part of IVF/ICSI treatment. Luteal phase support has been proven to be associated with higher rate of live birth rate. Human chorionic gonadotropin (HCG), and progestrone have been successfully used for luteal phase support in ovarian stim...

background: recent studies of uterine contractility in ivf�embryo transfer led us to consider an alternative, and possibly complementary, explanation for the high implantation rates of blastocysts. it has been demonstrated that myometrial contractile activity influences embryo implantation, possibly through mechanical displacement of embryos. objective: the aim of this study was to examine the ...

BACKGROUND The role of embryo transfer as regards the success of IVF/ICSI treatments is recognized but has not been comprehensively evaluated. In order to determine its importance, the degree of difficulty of 4807 embryo transfers after IVF/ICSI was analysed retrospectively. METHODS Logistic regression analysis identified the age of the subject, type of treatment (IVF versus ICSI), number of ...

background: to compare the pregnancy outcomes after two embryos versus three embryos transfers (ets) in women undergoing in vitro fertilization (ivf)/intracytoplasmic sperm injection (icsi) cycles. materials and methods: this retrospective study was performed on three hundred eighty seven women with primary infertility and with at least one fresh embryo in good quality in order to transfer at e...

background: recent reports have suggested that ultrasound-guided embryo transfer (ug-et) might improve pregnancy rates. objective: to determine whether transabdominal ug-et is a useful tool for increasing pregnancy and implantation rates in patients undergoing ivf or icsi. materials and methods: a prospective randomized clinical trial was conducted in 180 patients in order to compare embryo tra...

Embryo transfer policy and luteal supplementation was reviewed, comparing literature data and the results from the Maribor IVF Centre. A retrospective analysis of 1024 cycles in patients undergoing IVF, intracytoplasmic sperm injection (ICSI) or testicular sperm aspiration in unstimulated cycles was carried out using four different approaches for cycle monitoring. This showed that the most succ...
