Description of intervention(s) / exposure
All frozen embryo transfer treatment cycles initiated from 1st April 2008 to 31st March 2017 were retrospectively extracted from PIVET Medical Centre’s long-established, validated database where growth hormone or other adjuvants were used. The data was recorded as part of routine clinical practice at PIVET. Approval for analysis and publication of such retrospective data was initially provided by Curtin University Human Research Ethics Committee in 2010, annually renewed since then with the latest annual approval occurring on 20/8/2018.

Embryo gradings were rated as high, mid-range and low for blastocysts according to PIVET's modification of Gardner grading which categorises trophectoderm and inner cell mass characteristics. Cleavage-stage embryos were graded as high or low according to PIVET’s long-standing grading system based on blastomere numbers and features along with degree of fragmentation.

Summary
Brief summary
To determine the clinical pregnancy and live births arising from frozen embryos transferred (FET) which had been generated under the influence of IVF adjuvants given to women categorised as poor prognosis.
Our hypothesis is that growth hormone, but not other adjuvants, administered in stimulation cycles may improve oocytes with resultant benefits to embryo quality which in turn may result in improved Clinical Pregnancy and Live Birth rates in subsequent FET cycles.
