17beta-estradiol stimulates proliferation of spermatogonia in experimental cryptorchid mice.
AIM To investigate whether estrogen stimulates the proliferation of spermatogonia or induces spermatogenesis in cryptorchid mice. METHODS Mice were surgically rendered cryptorchid, then treated with different doses of 17beta-estradiol (E2) s.c. once a day. Mice were killed at sexual maturity (45 days of age), and histological analysis and immunofluorescence were performed. Serum follicle stim...
متن کاملP-145: Maturation Capacity and Viability Assessment of Human Immature Oocytes After Vitrification and In Vitro Maturation (IVM)
Background: 15% of oocytes collected in ART cycles are immature. These oocytes may be matured following IVM program. It is possible to cryopreserve the immature oocytes for further use in ART after application of IVM. The aim was to determine the maturation rate, morphology and viability of human immature oocytes after fresh IVM and vitrified-IVM program. Materials and Methods: 63 women who und...

متن کاملI-14: Vitrification of Human Immature Oocytes in IVM Program
The cryopreservation of immature GV oocytes by vitrification is offering attractive perspectives, since they represent an important pool of germ cells for women undergoing IVM cycles, or at risk of infertility for OHSS or PCOs, particularly those poor responders to gonadotropin stimulation, or in case of cancer. Therefore, it becomes necessary to optimize both cryopreservation technique as well...
