Every year, a dedicated team of professionals from our clinic attends the Pacific Coast Reproductive Society (PCRS) annual gathering in Palm Springs, California. One standout presentation was delivered by Dr. Emily Carter, a prominent figure in embryonic stem cell research.
Dr. Carter discussed the intriguing process of gene expression in human embryos. By the time an embryo reaches the 4-8 cell stage, it must activate its own genes and begin protein synthesis. This starts with the breakdown of maternal RNA, originally inherited from the egg. Subsequently, the embryo’s DNA takes over, producing its own RNA, ultimately leading to the generation of viable embryonic proteins. Embryos of lower quality or those with chaotic chromosome arrangements often struggle to undergo this process successfully, leading to an arrest in division.
Understanding these mechanisms is crucial for scientists as it sheds light on why some embryos thrive while others do not. This knowledge will enable us to select embryos with the highest potential for leading to healthy pregnancies.

Insights on Miscarriage Causes
Another compelling talk at the PCRS meeting was titled “Recurrent Pregnancy Loss: Maternal and Fetal Causes.” Here’s a brief overview of the key points shared.
Miscarriages affect about 25% of all pregnancies and are even more common in women over 35. Most spontaneous miscarriages happen during the first trimester. Both maternal and paternal factors can contribute to these losses, thus a comprehensive evaluation is suggested after two or more miscarriages. However, standard tests often yield non-diagnostic results in over 50% of cases, as many early pregnancy failures are linked to fetal chromosomal abnormalities. Genetic testing has revealed that these abnormalities are primarily due to incorrect chromosome numbers, often arising during ovulation or fertilization.
Fortunately, advancements in genetic testing now allow for more effective evaluations of fetal material following a miscarriage. One company, Genetix Solutions, has developed a method utilizing SNP arrays that can accurately identify chromosomal issues while distinguishing between maternal and fetal tissue. This new technique simplifies the analysis process, requiring less stringent handling of specimens, thus significantly reducing the time to receive results.
Now, couples facing the heartache of miscarriages can gain better insights into the reasons behind their losses, alleviating some of the frustration associated with unexplained pregnancy failures.

Exploring Cryopreservation Techniques
At this year’s PCRS meeting, I had the pleasure of sharing the stage with Dr. Megan Jones and Dr. Robert White, discussing cryopreservation methods. I focused on the importance of embryo vitrification alongside genetic screening, while my colleagues highlighted fertility preservation techniques.
Dr. Jones has made groundbreaking strides in ovarian tissue preservation. Although this method involves surgery, it has shown remarkable results. She explained how slicing the ovary into thin pieces and vitrifying them allows for future transplantation. While pregnancy may take time following the procedure, many women experience restored ovarian function within a few months.
Dr. White, on the other hand, spoke about the increasingly popular method of oocyte cryopreservation, or egg freezing. With the reliability of vitrification now established, egg banks are thriving in the U.S. The success rates for live births from vitrified eggs are comparable to those from fresh eggs, and no increase in birth defects has been observed. This method empowers women with greater reproductive options and autonomy.
In conclusion, the advancements presented at PCRS underscore the importance of ongoing research and education in reproductive health.
