The incidence of unexpected total fertilization failure in a conventional in vitro fertilization (IVF) cycle ranges
from 5% to 20%. One strategy to avoid cycle cancellation is the re-injection of unfertilized oocytes by the so-called
“rescue” intracytoplasmic sperm injection (ICSI). This paper aims to report the validity of performing a rescue
ICSI after a total fertilization failure in IVF. On May 2017 a 39-year-old woman presented to our Center. After
standard controlled ovarian stimulation, four oocytes were retrieved and inseminated by conventional IVF. No
oocytes were fertilized 18 hours after insemination. After 3 hours a rescue ICSI was performed and after 18 hours
three oocytes had extruded the second polar body and showed two pronuclei. Twenty-four hours later three embryos
were developed and transferred to the uterus. A single, uneve.. Read More»
