Porcine oocyte maturation in vitro : role of cAMP and oocyte-secreted factors: a practical approach [PDF]

, 2016
Polyspermy or the penetration of more than one sperm cell remains a problem during porcine in vitro fertilization (IVF). After in vitro culture of porcine zygotes, only a low percentage of blastocysts develop and their quality is inferior to that of in ...

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

#149 : Improved Embryo Quality of Infertile Women at Different Ages by Oral Administration of an Antioxidant Mixture

Fertility & Reproduction, 2023
Background and Aims: Oxidative stress is known to affect oocyte/embryo quality. In the previous meeting of ASPIRE, an antioxidant mixture (AOM) developed by us was shown to improve oocyte/embryo quality. Since oxidative stress is related to aging of body,

Estradiol and luteinizing hormone concentrations in the follicular aspirate during ovum pickup as predictors of in vitro fertilization (IVF) outcome

Middle East Fertility Society Journal, 2017
Background: A relationship between ‘oocyte quality’ and follicular fluid hormones is expected, since its formation coincides with the ‘oocyte maturation’ phase.

Oocyte Scoring Enhances Embryo-Scoring in Predicting Pregnancy Chances with IVF Where It Counts Most. [PDF]

PLoS ONE, 2015
Our center's quality improvement optimization process on many occasions anecdotally suggested that oocyte assessments might enhance embryo assessment in predicting pregnancy chances with in vitro fertilization (IVF).To prospectively compare a morphologic

In vitro production of bovine embryos derived from individual donors in the Corral® dish [PDF]

, 2017
Background: Since the identity of the embryo is of outmost importance during commercial in vitro embryo production, bovine oocytes and embryos have to be cultured strictly per donor.
