In vitro fertilization by intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) is the latest, and by far the most efficient, variant of micromanipulation-assisted fertilization, whereby a single spermatozoon is selected, aspirated into a microinjection needle and injected to the oocyte cytoplasm. The development of this technique is mainly linked to application in human assisted reproduction for which it enables fertilization with d...
متن کاملEmbryo transfer in days 2 to 4 following intracytoplasmic sperm injection: a prospective cohort study
Background: Improvement of assisted reproductive technique (ART) results in higher pregnancy rates from positive Beta HCG to take home baby statistics. Despite developments in culture media allowing blastocyst stage transfer, some centers apply second, third and sometimes fourth day post injection for embryo transfer. This study aimed to compare their reproductive outcomes. Methods : This p...
متن کاملEffects of Sperm Chromatin Integrity on Fertilization Rate and Embryo Quality Following Intracytoplasmic Sperm Injection
Sperm chromatin integrity has been being recognized as an important factor in male fertility. During normal fertilization, high quality sperm with intact chromatin are selected through natural selection in journey from vagina to fallopian tube. However, using Assisted Reproductive Techniques, particularly ICSI, the natural selection is bypassed. Therefore sperm with DNA breakage have the opport...
متن کاملThe Pregnancy Outcomes of Day 2 versus Day 3 Embryo Transfer: A Cross-Sectional Study
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 ...
متن کاملO-32: Effects of Intrauterine Injection of Recombinant Human Chorionic Gonadotropin before Embryo Transfer on Outcome of In Vitro Fertilization/Intracytoplasmic Sperm Injection: A Randomized Clinical Trial
Background: To evaluate the effectiveness of intrauterine injection of recombinant human chorionic gonadotropin (rhCG) before embryo transfer (ET). Materials and Methods: In this randomized placebocontrolled clinical trial, a total number of 182 infertile patients undergoing their first in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) were randomly assigned to receive 250 μg i...
