I-33: Early Assessment of Pregnancy Viability
Early determination of pregnancy viability is essential for women at risk for experiencing ectopic pregnancy or spontaneous abortion. Several markers of pregnancy viability have been identified including serial human chorionic gonadotropin (hCG) monitoring and sonography, in addition to several less commonly available biochemical markers. An ideal test would be readily available, inexpensive an...
متن کاملDiagnosis of the viability of early bovine embryos by fluorescence microscopy
A fluorescence microscopy technique using diacetylfluorescin (FDA) as a substrate has been tested for the evaluation of the viability of early bovine embryos. Five to 8-day old cattle embryos were incubated in PBS containing FDA concentrations of 1 : 400 000 or 1 : 800 000 for 3 to 5 min at room temperature. Embryos were then examined by reflected light fluorescence using a KP 490 and 520 barri...
متن کاملrelationship of number of embryos transferred with perinatal outcome of singleton pregnancy
background: singleton pregnancy with a live birth beyond 37 weeks of gestation is the ultimate goal of any assisted reproductive technology. however, singletons conceived after art are found to have a poor perinatal outcome in comparison to naturally conceived singletons. it was hypothesized that the outcome of singleton conceived after transfer of two or more embryos may be dependent on the sh...
متن کاملViability And DNA Fragmentation Assessment Of Bovine Embryos Vitrified By Different Methods
This study was conducted to compare the efficiency of four vitrification methods: straws in goblet, straws in Hasler device, cryloop and cryotop methods on blastocyst viability and the extent of apoptosis using the TUNEL technique in bovine embryos. Blastocysts were produced in vitro by standard procedures. The base medium for vitrification was Syngro holding medium. Embryos were vitrified by t...
متن کاملIncreasing The Number of Embryos Transferred from Two to Three, Does not Increase Pregnancy Rates in Good Prognosis Patients
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. MaterialsAndMethods 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 each ...
