We evaluated the uterine cavity by sonohysterography (SHG) in patients with recurrent failed IVF-embryo transfer despite transfer of good quality embryos, compared with other diagnostic methods. We found that SHG is highly valuable and should be applied routinely as a first-line, office-based diagnostic tool in such cases.

Cryopreservation of human gametes and embryos has become an essential part of assisted reproduction. Successful cryopreservation of human blastocysts is increasingly relevant as extended in-vitro culture of human embryos becomes more common, permitting routine use of blastocyst transfer in IVF programmes. This reduces the number of embryos transferred, thereby reducing ...
