In vitro culture of human ovarian tissue the following cryopreservation is proposed for follicular development. There are no techniques that guarantee successful maturation of the follicles within the excised tissue. The viability of cultured human ovarian tissue improved by adding some growth factors to the culture media. The efficiency of vitrification as the cryopreservation method for human...

Background The conventional freezing and vitrification are different cryopreservation protocols for fertility preservation in cancer patients. The high effectiveness of vitrification for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. Follicular growth, ultrastructure, and apoptosis incidence in human ovarian tissue following vitrification/warming and after...

Background The high effectiveness of vitrification, as a cryopreservation protocol, for human oocytes and embryos is shown, whereas data on human ovarian tissue are limited. This study aimed to assessment of follicular growth, ultrastructure, and apoptosis incidence in human ovarian tissue following vitrification/warming and after culture in the presence of LIF.

background: ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. this study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (figla), growth differentiation factor-9 (gdf-9), follicle-stimulating hormone receptor (fshr), and kit ligand after v...

Background: Ovarian tissue cryopreservation is an alternative strategy to preserve the fertility of women predicted to undergo premature ovarian failure. This study was designed to evaluate the expression of folliculogenesis-related genes, including factor in the germline alpha (FIGLA), growth differentiation factor-9 (GDF-9), follicle-stimulating hormone receptor (FSHR), and KIT LIGAND after v...

objective: this study aimed to evaluate the incidence of apoptosis in vitrified and non-vitrified human ovarian tissue by the use of morphological analysis and apoptosis assay techniques. methods: we obtained human ovarian tissue biopsies from 30 women who underwent elective caesarean sections. tissues were transported to the laboratory in pre-warmed, equilibrated leibovitz l-15 medium within 2...

the capability to preserve human oocytes, blastocysts, ovarian tissue and spermatozoa is an important tool in human assisted reproductive techniques. this preservation allows patients undergoing chemotherapy or radiotherapy to preserve their fertility, and helps to attain all benefits from the costly ovarian superovulation therapies prior to art. the primary goal in establishing an appropriate ...

from december 2000 until 2010, the researchers at royan institute conducted a wide range of investigations on ovarian tissue cryopreservation with the intent to provide fertility preservation to cancer patients that were considered to be candidates for these services. in 2010, royan institute established the royan human ovarian tissue bank as a subgroup of the embryology department. since its i...

Background In vitro culturing and retransplantion of vitrified- warmed ovarian tissue are two ways to restore fertility after radiation or chemotherapy.This study aimed to evaluate the incidence of apoptosis in vitrified human ovarian tissue after warming, long term culturing and xenotransplantation by morphological analyses and apoptosis genes expression evaluation.
