Shi and associates found in a prior study of women with PCOS that the live birth rate was higher with frozen embryo transfer
There is no evidence that the time from egg retrieval to embryo transfer
affects live birth rates in a freeze-all strategy.
(ET) performed on the second or third day of fertilization when the embryos are at the 4-8 cell stage has an implantation rate lower than 20% (1-3).
As it is obvious from the data presented in Table 1, the embryo transfer
efficiency is higher in beef cattle breeding.
Influence of pressure changes during embryo transfer
on blastocyst viability.
Single embryo transfer
with comprehensive chromosome screening results in improved ongoing pregnancy rates and decreased miscarriage rates.
Nine of the 26 JS cows became pregnant following JB embryo transfer
, but one calf was stillborn after 250 d of pregnancy.
Animal strain may affect embryo transfer
outcome, for example, DBA/2J mouse strain that is widely used for biomedical research suffers from poor reproductive performance (3) while F1 C57BL/6xDBA/2 (B6D2F1) and FVB/N strains are routinely used in ET programs.
Meclofenamic acid extends donor-recipient asynchronyc in equine embryo transfer
Drafting a federal embryo transfer
law is easy enough, but assuring enforcement by regulators and compliance by physicians and patients presents near insurmountable barriers.
8%) ET = embryo transfer
; ETC = embryo transfer
He makes the claim that, if such a policy were enacted and resulted in a lower rate of multiples but maintained a steady birth rate, restrictions on embryo transfer
would not limit reproductive rights.
