Release of sICAM-1 in Oocytes and In Vitro Fertilized Human Embryos

BACKGROUND During the last years, several studies have reported the significant relationship between the production of soluble HLA-G molecules (sHLA-G) by 48-72 hours early embryos and an increased implantation rate in IVF protocols. As consequence, the detection of HLA-G modulation was suggested as a marker to identify the best embryos to be transferred. On the opposite, no suitable markers ar...

Reproductive efficiency of human oocytes fertilized in vitro

Developmental competence of Dromedary camel oocytes fertilized in vitro by frozen-thawed ejaculated and epididymal spermatozoa

The present study aimed to compare the in vitro fertilizing capacity of frozen-thawed ejaculated and epididymal spermatozoa in order to standardize the semen preparation protocol for camel in vitro fertilization (IVF). Semen samples were collected from 7 Dromedary camels by means of artificial vagina (AV). Ten cauda epididymes were obtained from slaughtered adult camels, isolated, incised and r...

P-120: Meiotic Spindle Visualization and Zona Pellucida Birefringence in Relation to Morphology of In Vivo and In Vitro Matured Human Oocytes of In Vivo and In Vitro Matured Human Oocytesof In Vivo and In Vitro Matured Human Oocytes

Background: The meiotic spindle plays an important role in the oocyte during chromosome alignment and separation at meiosis. The zona pellucid (ZP) is a dynamic matrix composed of filaments with the properties that might reflect the history of oocyte cytoplasmic maturation. Since, spindle and ZP in living oocytes are highly birefringent, their structures can be viewed noninvasively by using a P...
