background: in this study, we evaluated the incidence of apoptosis at the ultrastructural levels and expression of some apoptosis-related genes in vitrified human ovarian tissue just after warming. methods: human ovarian tissue biopsies from 23 women after caesarean section were transported to the laboratory within 2 hours, and then they were cut into small pieces. some pieces were vitrified an...
Cryopreservation of human gametes and embryos has become an essential part of assisted reproduction. It is now possible to cryopreserve gametes and embryos at their different stages of development. It allows patients undergoing chemotherapy or radiotherapy to preserve their fertility, and helps to attain all benefits from the costly ovarian superovulation therapies prior to assisted reproductiv...
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...
Ovarian reserve (OR) screening of the general population is generally not advocated as it has not been conclusively established to reflect immediate potential for natural conception, while it may also potentially create anxiety for women. However, in this paper, we argue in support of screening of the general population for diminished OR. First, OR tests such as measurements of anti-Müllerian h...
OBJECTIVE To explore the effective isolation method for preantral follicles from human frozen-thawed ovarian tissue. METHODS The ovarian cortical tissue was frozen by direct cover vitrification (DCV). The frozen-thawed ovarian tissue was used for isolation of preantral follicles with collagenase combined with mechanical method and mechanical method alone, respectively. RESULTS 1. There was ...
