Vitrification of human ICSI/IVF spermatozoa without cryoprotectants: new capillary technology.
The aim of this study was to develop and to test the standardized aseptic technology of permeable cryoprotectant-free vitrification of human spermatozoa in capillaries (for intracytoplasmic sperm injection [ICSI] or in vitro fertilization [IVF]). To test the effect of vitrification on basic sperm parameters, each of 68 swim-up-prepared ejaculates from oligo-astheno-terato-zoospermic patien...
متن کاملFirst trimester trophoblast and placental bed vascular volume measurements in IVF or IVF/ICSI pregnancies.
STUDY QUESTION Are first trimester trophoblast volume (TV) and placental bed vascular volume (PBVV) different in IVF or IVF/ICSI pregnancies in comparison with spontaneously conceived pregnancies? SUMMARY ANSWER Any possible abnormal placentation in IVF or IVF/ICSI pregnancies in comparison with spontaneously conceived pregnancies is not detected by a difference in PBVV or TV at an early gest...
متن کاملRescue ICSI of unfertilized oocytes after IVF.
BACKGROUND Failed fertilization after IVF occurs in 10-20% of cycles. Conflicting results of rescue fertilization by ICSI have been reported. We therefore compared the success rate in terms of fertilization and pregnancy of cycles in which rescue ICSI was performed with those from a matched control group of primarily ICSI cycles. METHODS Unfertilized oocytes from IVF cycles with total fertili...
متن کاملPerinatal risks after IVF and ICSI.
Pregnancies that occur after infertility treatment, particularly after assisted reproduction, constitute high-risk pregnancies. Occurrences of conditions such as high blood pressure, preeclampsia, growth retardations and bleeding are higher in comparison with the norm of spontaneously entered pregnancies. The rate of premature births and the frequency of intrauterine deaths are much higher than...
متن کاملComparison of clinical outcomes between in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in IVF-ICSI split insemination cycles
OBJECTIVE This study aimed to compare the clinical outcomes between in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in sibling oocytes. Additionally, we evaluated whether the implementation of split insemination contributed to an increase in the number of ICSI procedures. METHODS A total of 571 cycles in 555 couples undergoing split insemination cycles were included i...
