متن کامل“Short Paper” Application of Gamma Irradiation to Increase the Motility and Viability of Bovine Sperm after Freezing and Thawing
This study was conducted to determine the suitable dose of gamma rays for increasing sperm motility and viability after thawing and to assess its effects on malondialdehyde concentration and the rate of sperm DNA strand breaks. Sperm samples in liquid nitrogen were irradiated at doses of zero, 0.1, 0.3, 0.5, 0.7 and 0.9 Gy. The sperm quality and quantity parameters were evaluated before and aft...
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...
