Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The main outcome of this study is to analyse the rate of live births with the relative gestational period and neonatal weight and still death and neonatal death per each single blastocyst transfer, both fresh and warmed. Secondary outcomes include the incidence of obstetric pathologies, gestational diabetes and pre-eclampsia, and defects of placentation.
The study database included all pregnancies occurred after both a single fresh and warmed blastocyst transfer between the five-year period from 2014 to 2018 at Humanitas Fertility Centre. The inclusion criteria were all patients, without any age limitations, which underwent either FIVET or ICSI and only transferred a single blastocyst. With regards to exclusion criteria, the following were considered: ovodonation, suspended cycles and embryos which were subjected to pre-implantation genetic testing.The investigator performed a comparison of maternal and neonatal outcomes in these pregnancies which occurred in the same period of time and in the same age-group of women.
