متن کاملGnRH agonist versus GnRH antagonist in in vitro fertilization and embryo transfer (IVF/ET)
Several protocols are actually available for in Vitro Fertilization and Embryo Transfer. The review summarizes the main differences and the clinic characteristics of the protocols in use with GnRH agonists and GnRH antagonists by emphasizing the major outcomes and hormonal changes associated with each protocol. The majority of randomized clinical trials clearly shows that in "in Vitro" Fertiliz...
متن کاملeffects of single dose gnrh agonist as luteal support on pregnancy outcome in frozen-thawed embryo transfer cycles: an rct
background: there is no doubt that luteal phase support is essential to enhance the reproductive outcome in ivf cycles. in addition to progesterone and human chorionic gonadotropin, several studies have described gnrh agonists as luteal phase support to improve implantation rate, pregnancy rate and live birth rate, whereas other studies showed dissimilar conclusions. all of these studies have b...
متن کاملEmbryo transfer using cryopreserved Boer goat blastocysts
The aim of this trial was to evaluate the effect of embryo cryopreservation techniques on the survivability of embryos and fertility following transfer to Boer goat does. The oestrous cycles of 27 mature recipients Boer goat does were synchronised using controlled internal drug release dispensers (CIDR’s) for 16 days. At CIDR removal, does were injected with 300 IU eCG. The recipient does were ...
