Abstract

OBJECTIVE(S):

The aim of this study was to compare the patient characteristics, type of genetic disease and inheritance, volume of activity, practice patterns and pregnancy outcomes, in private versus publically funded IVF pre-implantation genetic testing (PGT) for translocation (IVF-PGT-SR) and aneuploidy (PGT-A) periods.

STUDY DESIGN:

This study retrospectively analyzed data during both privately funded period (PRP) and publically funded period (PUP) of assisted reproductive technology (ART) for a total of 275 patients. 83 patients underwent IVF-PGT-SR and 192 patients underwent IVF-PGT-A. Given that PGT-SR is a chromosomal abnormality hereditary in nature, whereas PGT-A is sporadic in addition to the contrasting funding policies, the two cohorts were analyzed separately. To achieve the proposed objective, the two groups under analysis were grouped in accordance with their respective coverage systems for infertility.

RESULTS:

Among translocation patients, 94 normal/balanced embryos were obtained from 47 IVF-PGT cycles in PRP whereas 145 embryos were obtained from 92 IVF-PGT cycles in PUP. The average number of embryos transferred per embryo transfer cycle was significantly lower in PUP in comparison to PRP (1.13 vs. 1.74, p < 0.0001). 13 singletons and 2 sets of twins were conceived in PRP. 14 singletons were conceived in PUP. Regardless of funding period, there were more reciprocal translocation carriers (79.4% in PRP and 76.4% in PUP) and more male carriers (82.4% in PRP and 60% in PUP), of which the majority had abnormal sperm parameters. Among aneuploidy patients, on average 2.5 embryos in PRP and 1.4 embryos in PUP were transferred per ET cycle (p = 0.05). There was a 13.3% increase in number of IVF-PGT-A attempts per patient in PRP compared to PUP. Live birth rate per IVF-PGT-A was higher in PRP (29.7% vs. 15%, P = 0.02), which consisted of 48 singletons and 18 multiparous pregnancies in PRP and 9 singletons in PUP.

CONCLUSION(S):

Public coverage of ART is associated with a greater utilization ART, as well as a reduced number in embryo transfer (ET) per cycle, a lower proportion of cycles resulting in successful pregnancy and a lower multiple birth rate. Our study ultimately shines light on the effect of providers' and patients' monetary conscious on pregnancy outcome.
