Clinical validation of a closed vitrification system in an oocyte-donation programme.
Controversy exists about the risk of microbiological contamination from direct contact with unsterile liquid nitrogen during oocyte vitrification. The aim of this observational study was to evaluate the effectiveness of oocyte vitrification using a high-security closed vitrification system in a donation programme. Oocyte vitrification was performed using CBS High Security closed straws (Cryo Bi...

متن کاملOocyte Donation: an Overview
The use of donor oocytes has expanded the scope of assisted reproductive technology (ART) for women with poor oocyte quantity and quality. In vitro fertilisation with oocyte donation (IVF-OD) is considered to give better implantation, pregnancy, and livebirth rates compared to IVF with autologous oocytes. Maternal age, infertility factors, BMI, smoker status, and ethnicity reduce reproductive o...
متن کاملGnRH agonist versus GnRH antagonist in oocyte donation cycles: a prospective randomized study.
BACKGROUND The specific role of LH in folliculogenesis and oocyte maturation is unclear. GnRH antagonists, when administered in the late follicular phase, induce a sharp decrease in serum LH which may be detrimental for IVF outcome. This study was performed to evaluate whether the replacement of GnRH agonist (triptorelin) by a GnRH antagonist (ganirelix; NV Organon) in oocyte donation cycles ha...
متن کاملRelevance of assisted hatching in an oocyte donation programme using egg cryobanking: a prospective randomised study.
OBJECTIVE The objective of this prospective randomised study was to evaluate if there is an improvement in clinical outcomes when assisted hatching (AH) is performed in embryos derived from vitrified/warmed oocytes in an ovum donation programme using egg cryobanking. STUDY DESIGN Sixty oocyte recipients in a donation programme using egg cryobanking were randomly allocated to the assisted hatc...
