It is therefore proposed that the transfer of a single blastocyst is the best treatment for most patients, given the high implantation rates of fresh transfers, and that it is now possible to cryopreserve supernumerary blastocysts effectively.
The OPR for fresh transfers and FETs was similar in both groups (control SET 39.1 versus 44.4%, P= 0.4; CCS-SET 59.7 versus 51.8%, respectively, P= 0.4).
Of the 78 patients with fresh transfers (42 with 1 fresh embryo, 34 with 2 embryos and 2 with 3 embryos), 24 (31%) were pregnant at 12 weeks.
When these pregnancies are excluded and only fresh transfers are considered, the ectopic pregnancy rate remains similar for day 3 and day 5 at 3.5% (22/615) and 3.3% (9/271), respectively.
In simulation with only fresh transfers available, no difference in effectiveness of treatments consisting of up to three cycles was found: 43.28% (95% CI 42.32%–44.26%) for HP-hMG and 42.58% (95% CI 41.61%–43.56%) for r-hFSH.
When fresh and frozen transfers in cycles 2 and 3 were analyzed separately, r-hFSH was associated with more frozen transfers and HP-hMG with more fresh transfers; the difference was significant in cycle 2 for both fresh and frozen and in cycle 3 for frozen transfers only.

To evaluate the effects of low body mass index (BMI) on in vitro fertilization (IVF) outcomes in fresh transfer cycles.
To examine the available evidence to assess if cryopreservation of all embryos and subsequent frozen embryo transfer (FET) results in better outcomes compared with fresh transfer.
Foetuses derived from the fresh transfer of IVP blastocysts were heavier (6.4±0.2 g versus 5.8±0.2 g, respectively, P<0.05) and longer (5.2±0.1 cm versus 4.8±0.1 cm, respectively, P<0.01) than those derived from fresh in vivo blastocysts.
We met a new surrogate in November, and we did a fresh transfer with a different egg donor at a clinic in L.A. in March.
