In conclusion, this prospective, randomized study demonstrates that (at least in cases where a sufficient number of fertilized oocytes are available), it does not make a difference whether transfer is performed on day 2 or day 3, since similar pregnancy and implantation rates can be achieved. Moreover, these findings indicate that embryo transfers can be safely scheduled at the convenience of the patient and the centre.
The pregnancy and implantation rates for transfer of blastocysts versus transfer of day 2 or day 3 embryos is in the similar range. A pregnancy rate of 38% and an implantation rate of 23% has been reported (). In the present study, the pregnancy rates were 47.9% in the day 2 group and 46.8% in the day 3 group and the implantation rate was 23.8% in both groups. The patient selection in both studies was similar. In the study by Jones et al. only patients aged
Am on day 2 today, started with a large boiled potato with half tsp olive oil and a cup of green tea, I had cucumber and carrots in between and I half veggie stir fry (carrot, cabbage, zucchini, pepperoni, mushrooms and paprika) for lunch and drunk already 2.5liters water, however, I am planning to have boiled spinat with one sweet potato for dinner would that be OK or am I allowed to eat potatoes once this day?,
I am feeling great ! ann cant wait to weigh myself after day 3 :-))
This prospective study compares day 2 and day 3 embryo transfers with true randomization and of sufficient size to prove or refute a clinically relevant difference in pregnancy rate between both procedures. A minimization procedure was used on a group of patients with at least seven normally fertilized oocytes taking into account two important prognostic factors, i.e. the age of the patient and the procedure of fertilization (IVF or ICSI). The number of embryos transferred was controlled for by a uniform policy of embryo transfer. In the present study, pregnancy and embryo implantation rates were comparable in day 2 and day 3 transfer groups (47.9 and 23.8 % in the day 2 group versus 46.9 and 23.8% in the day 3 group). A statistically lower percentage of excellent and good quality embryos was obtained after culture until day 3 versus day 2 (10.3 and 40.1% versus 12.9 and 44.2%; P
