Research Question: Among women who considered planned oocyte cryopreservation, does decision regret differ between those who pursued planned oocyte cryopreservation and those who did not?
Design: A survey was e-mailed to all women who presented for an initial consultation for planned oocyte cryopreservation between January 2016 and December 2021 using a secure REDCap platform. The survey comprised questions on demographics, reproductive planning and the validated Decision Regret Scale (DRS). Univariable and multivariable models were fitted to compare decision regret in the group who had proceeded with planned oocyte cryopreservation with the group who had not.

Research Question: Could a predictive model, using data from all US fertility clinics reporting to the Society for Assisted Reproductive Technology, estimate the likelihood of patients using their stored oocytes?
Design: Multiple learner algorithms, including penalized regressions, random forests, gradient boosting machine, linear discriminant analysis and bootstrap aggregating decision trees were used. Data were split into training and test datasets. Patient demographics, medical and fertility diagnoses, partner information and geographic locations were analysed.

Study Question: Are there significant differences in fertility outcomes between transferring two cleavage-stage embryos in a single fresh cycle and transferring one cleavage-stage embryo in a fresh cycle and one blastocyst-stage embryo in the subsequent frozen-thawed cycle?
Summary Answer: In women aged <38 years with two embryos available, transferring one cleavage-stage embryo in a fresh cycle and one blastocyst-stage embryo in the subsequent frozen-thawed cycle increased live birth rates and decreased multiple live birth rates compared to transferring two cleavage-stage embryos in a single fresh cycle.
What Is Known Already: The strategy of repeated single embryo transfer (SET) has emerged as a solution to address the reduced live birth rates associated with SET per cycle. There is substantial evidence indicating that the cumulative live birth rate after repeated SET is comparable to that of double embryo transfer (DET), while significantly reducing the incidence of multiple pregnancies.

We share experiences in advocating to defend in vitro fertilization (IVF) in Virginia, Missouri, and Mississippi; provide historical context on the "Personhood" anti-IVF movement; and discuss why "embryo donation" is a more accurate term than "embryo adoption." Some individuals and communities have a deeply held belief that a fertilized oocyte is a very early human life, and we will likely never change their minds. In the fertility community, most providers consider embryos to be an important part of the continuum between gametes (sperm and eggs) to live birth.
