In vitro development of secondary follicles from cryopreserved rhesus macaque ovarian tissue after slow-rate freeze or vitrification.
BACKGROUND Ovarian tissue cryopreservation is the only option for preserving fertility in prepubertal girls and cancer patients requiring immediate treatment. Following ovarian tissue cryopreservation, fertility can be restored after tissue transplant or in vitro follicle maturation. METHODS Macaque (n= 4) ovarian cortex was cryopreserved using slow-rate freezing (slow freezing) or vitrificat...
متن کاملO-22: Bioenergy/Oxidative Status of Human Ovarian Tissue Cryopreserved by Slow Freezin or Vitrification
Background Ovarian tissue cryopreservation represents a promising strategy to preserve the ovarian function in cancer patients. It is usually performed by slow freezing/rapid thawing (SF/RT). Recent studies emphasize an ultrarapid cryopreservation procedure, vitrification/warming (V/W), since it might prevent damages due to ice crystal formation. Comparative studies between the cryopreservation...
متن کاملSurvival Rate of Preantral Follicles Derived From Vitrified Mouse Ovarian Tissue by Cryotop
Purpose: The aim of this study was to investigate the growth and survival rate of preantral follicles isolated from vitrified ovarian tissue by cryotop.Materials and Methods: Ovaries of 14-day-old NMRI mice were separated and divided into three groups fowling as: vitrified, toxicity tested and control groups. Ovaries in the experimental groups were immersed in equilibration and vitrification so...
متن کاملEmbryo development after heterotopic transplantation of cryopreserved ovarian tissue.
BACKGROUND Cancer treatments, including chemotherapy, radiotherapy, and radical surgery, can induce premature menopause and infertility in hundreds of thousands of women of reproductive age every year. One of the ways to possibly preserve fertility before these treatments is to cryopreserve ovarian tissue for later transplantation. We aimed to restore fertility by cryopreservation and transplan...
متن کاملIn vivo and in vitro strategies to support caprine preantral follicle development after ovarian tissue vitrification.
The aim of the present study was to compare fresh and vitrified goat ovarian tissue after autotransplantation and in vitro culture. Adult goats were completely ovariectomised and each ovarian pair was sliced and distributed among six different treatment groups: fresh control, fresh transplant, fresh culture, vitrified control, vitrified transplant and vitrified culture. Follicular morphology, d...
