Background: Microfluidic sperm sorting procedure or chip technique is a chemical-free method of selecting using disposable chip. It new gentle alternative for processing which has been produced to obtain with higher rates motility and better morphology, as well reduce DNA fragmentation in high nearly undetectable levels. We aimed evaluate techniques on clinical pregnancy patients who underwent ...

BACKGROUND The influence of embryo loading time (ELT) and the time interval between embryo loading and embryo transfer (TIEL-ET) on the success of IVF/ICSI is unknown. METHODS In a prospective cohort study, we aimed to ascertain the influence of ELT and TIEL-ET on ongoing pregnancy rate (OPR) and life birth rate (LBR). Data from 603 consecutive embryo transfers between January 2008 and Decemb...

Background The objective was to evaluate whether extending the embryo culture period from 2 to 3 days would yield a more optimal selection of viable embryos, thereby increasing the pregnancy rat. MaterialsAndMethods We have retrospectively analyzed pregnancy rates in the patients who had embryo transfer either on day 2 (582 patients) or on day 3 (387 patients) post-insemination over a 10-month ...

Prior to ICSI the cumulus-oophorous-complex of the oocyte is commonly remove with impure animal-derived hyaluronidase of low strength. The lower strength of the enzyme, the high concentration of impurities and the necessity of extensive time-dependent mechanical denudation damages of the oocytes, increases the risk of lysing the oocytes and the transfer of animal-derived pathogens. All this can...

cumulative embryo score (ces) is one of the many embryo scoring methods which have been developed to help clinicians to transfer high quality embryos and predict pregnancy rate in assisted reproductive techniques (art) cycles. regarding the existing difference in ces calculation this study was done to compare two methods in order to determine the more practical and preferable one. in a retrospe...

OBJECTIVE To describe a patient selection method for elective single embryo transfer (eSET), emphasizing inclusion criteria and results. METHODS This retrospective study included all cases seen in a private clinic between June 2011 and December 2016, in La Paz, Bolivia (3600 meters above sea level). Elective single embryo transfer was the method of choice in 34 IVF/ICSI cycles, all in the bla...

BACKGROUND This was a retrospective study to determine if diagnostic testicular biopsy followed by cryopreservation should be the procedure of choice for all patients with testicular failure. METHODS The first part of the study analysed 97 ICSI cycles scheduled with frozen-thawed testicular sperm for 69 non-obstructive azoospermia (NOA) patients. The second part focused on a subgroup of 32 pa...

2Fertility Clinic, Vilnius, Lithuania Human leukocyte antigen G (HLA-G) is a non-classical HLA class I molecule which can be expressed in the membrane-bound or soluble form and is well known for its tolerogenic properties. Increasing interest is now being addressed to the soluble forms, because they might have prognostic properties in the implantation and pregnancy process. The aim of our study...

Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...

BACKGROUND Polycystic ovary syndrome (PCOS) patients are at increased risk of pregnancy complications, which may impair pregnancy outcome. Transfer of fresh embryos after superovulation may lead to abnormal implantation and placentation and further increase risk for pregnancy loss and complications. Some preliminary data suggest that elective embryo cryopreservation followed by frozen-thawed em...
