Successful live birth after rescue ICSI following failed fertilization

Successful fertilization and pregnancy following ICSI and electrical oocyte activation.

In a total of 1048 intracytoplasmic sperm injection (ICSI) cycles, motile spermatozoa from four out of 424 patients (0.9%) failed to fertilize oocytes, despite an apparently successful ICSI procedure. No activation was observed in these injected oocytes. The spermatozoa from three of the four patients were injected into unfertilized mouse oocytes by ICSI (mouse test) to evaluate their oocyte ac...

Rescue angioplasty after failed thrombolysis--high mortality despite successful procedure.

Cumulative live-birth rates after in vitro fertilization.

BACKGROUND Outcomes of in vitro fertilization (IVF) treatment are traditionally reported as pregnancies per IVF cycle. However, a couple's primary concern is the chance of a live birth over an entire treatment course. METHODS We estimated cumulative live-birth rates among patients undergoing their first fresh-embryo, nondonor IVF cycle between 2000 and 2005 at one large center. Couples were f...

Cumulative Live Birth Rates after In Vitro Fertilization

Background: In vitro fertilization (IVF) has become increasingly common, today representing about 3% of all live births in some countries. Most patients have to undergo more than one treatment in order to achieve a live birth. Thus cumulative live birth rates are highly interesting to the patients. The most important health problem in IVF is the high rate of multiple births, leading to increase...

Successful live birth after transfer of blastocyst and frozen blastocyst from rescue ICSI with application of polarized light microscopy for spindle examination on unfertilized eggs

This article aims to report successful live births after transfer of fresh blastocyst or vitrified/warmed blastocyst derived from intracytoplasmic sperm injection (ICSI) on day-1 of unfertilized mature eggs (so-called "rescue ICSI") with spindle examination using polarized light microscopy. Two couples who had rescue ICSI performed achieved a positive pregnancy result after the transfer of a fr...
