One in six couples suffers from subfertility problems. Assisted reproductive techniques including in vitro fertilization (IVF) have helped overcome many subfertility problems and 9 million babies have been born worldwide with the help of IVF. IVF is one of the fastest growing fields of medicine, but despite technical developments in recent decades, improving embryo implantation rates remains one of the biggest challenges.
Only about 30% of transferred embryos implant and develop properly, so it is common to artificially increase the IVF success rate by transferring multiple embryos. This leads to an increased risk of multiple pregnancies that can lead to significant health complications for the mother and future babies.
While fertility clinics share a common goal of improving pregnancy rates, the methods, technologies, and processes to achieve this goal are vastly diverse. This inconsistency confuses patients and makes it difficult for fertility specialists such as embryologists, obstetricians and gynecologists to adapt to different technologies and keep up with the latest trends in the IVF market. Understanding the processes necessary to improve and provide the best health service to patients is key to successful fertility clinics.
This study aims to explore the state of the art in IVF and highlight current trends in fertility clinics. The results of the study indicate that, despite numerous technological advances in the field of IVF, standardizing the criteria used in the embryo selection process remains a challenge. Despite the technology available, clinical procedures for recognizing viable embryos still rely on the experience of an embryologist to decide which embryo is most viable for transfer.
