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...

Submit Manuscript | http://medcraveonline.com for 5 years due to polycystic ovary syndrome underwent some unsuccessfully low-complexity infertility treatments, then she underwent IVF/ICSI in October 2015. The patient opted for freezing-all embryos for subsequent transfer. In June 2016, two frozen-thawed embryos were transferred in the blastocyst stage. Twelve days after the embryo transfer, the...

In the present study, embryo transfer was performed using frozen-thawed embryos to establish a SPF colony of human apolipoprotein (a) (apo(a)) transgenic rabbits. Apo(a) transgenic rabbits were kept under conventional condition and were infected with Bordetella bronchiseptica. Embryos at the morula stage were collected and stored in liquid nitrogen. After thawing, the in vitro survival rate was...

The aim of this trial was to evaluate the effect of embryo cryopreservation techniques on the survivability of embryos and fertility following transfer to Boer goat does. The oestrous cycles of 27 mature recipients Boer goat does were synchronised using controlled internal drug release dispensers (CIDR’s) for 16 days. At CIDR removal, does were injected with 300 IU eCG. The recipient does were ...

The aim of this study was to assess two models of sperm collection on the quality and fertility of thawed spermatozoa from Black Manchega rams, a threatened breed. Sperm samples were collected by electroejaculation and postmortem from each male. Samples were diluted with Biladyl and frozen. Motility (subjective and objective by means of computer-assisted semen analysis), membrane integrity, and...

To evaluate whether duration of autologous oocyte vitrification has an impact on in-vitro fertilization (IVF) cumulative live birth rates (cLBR) after fresh or frozen embryo transfers. We identified IVF cycles using vitrified/thawed oocytes from 2010-2020. Ovarian stimulation, vitrification/thawing, IVF/ICSI, culture/transfer were performed published protocols. Duration cryopreservation for the...

Obtaining sexed sperm from previously frozen doses (reverse-sorted semen [RSS]) provides an important advantage because of the possibility of using the semen of bulls with desired genetic attributes that have died or have become infertile but from whom frozen semen is available. We report the efficiency of RSS on the pregnancy rate and birth rate of calves in a large-scale program using ovum pi...

BACKGROUND To evaluate the safety of cryopreservation in combination with IVF and ICSI, prenatal diagnosis and neonatal outcome were investigated in children conceived from frozen-thawed ICSI embryos (cryo ICSI) and frozen-thawed IVF embryos (cryo IVF). Data were also compared with earlier published results from fresh ICSI and IVF embryos. METHODS Questionnaire data and results of physical ex...
