Embryo access for research purposes is being hindered by logistical barriers, according to Hartshorne. A significant factor is that the majority of in vitro fertilization (IVF) procedures take place in clinics that do not collaborate with academic institutions engaged in research.
Currently, embryos are primarily kept at the facilities where they were formed. The transportation of these embryos to research laboratories often proves challenging. Clinic personnel often lack the necessary resources and time to manage the complicated legal documentation required for donating embryos to specific studies, Hartshorne pointed out. She advocates for the establishment of a centralized embryo bank to simplify the donation process for research purposes.
The bureaucratic processes involved pose a notable hurdle. Although the UK is recognized for its stringent regulatory framework surrounding reproductive technologies—which is often regarded as exemplary by experts worldwide—it also presents substantial bureaucratic challenges, Hartshorne noted. “When patients reach out expressing their willingness to donate embryos or eggs for research, I typically have to decline, as navigating the required paperwork could take upwards of a year,” she explained.
Finding a middle ground may be essential. Research involving embryos holds considerable promise for advancing medical knowledge. As highlighted in the film Joy, such research has the potential to revolutionize healthcare and positively impact many lives.
“Research is the driving force behind progress and innovation; it’s crucial for the future of IVF and reproductive science,” Hartshorne emphasized.

Scientists are exploring methods to generate embryos using stem cells, eliminating the need for eggs or sperm. The ethical implications of allowing these embryo-like entities to develop further provoke important questions.
Researchers have conducted experiments by implanting these “synthetic embryos” into monkeys. While the outcomes have produced a temporary pregnancy-like state, actual fetal development has yet to occur.
Other scientists are also investigating the possibility of achieving pregnancies in cows using synthetic embryos. Reproductive biologist Carl Jiang aims for a successful cow pregnancy that can persist for at least 30 days.
