Ovulatory dysfunction is one of the most common causes of infertility — yet its genetic roots remain largely unexplored. In this article, Senior Embryologist Dr. Erin DiPietro shares what inspired her to investigate this topic and what her research reveals about the intricate role genetics can play in reproductive health.

As a Senior Embryologist at Illume Fertility, I have the utmost respect and admiration for people who undergo in vitro fertilization (IVF) or any other fertility treatment. I see every day how much physical, emotional, and financial effort is invested in the hope of having a child.
It can be just as frustrating for clinicians and laboratory staff when the tools we already have, such as bloodwork, ultrasounds, and embryo assessment, do not always give us the answers we need.
That is what led me to dig deeper into the root causes of certain infertility diagnoses that remain unexplained. For me, the next frontier was genetics. I believe genetics is the future of medicine, and it is going to become an even larger part of IVF over the coming years.
That idea both excites and motivates me.
Ovulatory dysfunction, when a person does not ovulate regularly or at all, is one of the most common causes of infertility.
Conditions such as polycystic ovary syndrome (PCOS) and primary ovarian insufficiency (POI) fall under this umbrella, but there are also many patients whose ovulatory challenges do not fit neatly into either category.
The aim of my research was simple in theory but ambitious in scope: identify all of the genetic variants already established in the literature in humans and compile that information into one place. My hope was that creating this resource would help researchers and clinicians see patterns that may have been invisible when looking at each small study on its own.
This project became an integral part of my doctoral dissertation at Clemson University. I conducted what is called a scoping review, systematically gathering and summarizing every relevant study on the genetics of ovulatory dysfunction in humans.
Much of what exists in this field comes from small scale studies, even single case reports. By compiling them all, I was able to cross reference findings and increase confidence in the results.
I also performed genetic categorization analysis, which revealed that different types of ovulatory dysfunction are associated with unique genetic profiles.
Research Terms, Explained
Scoping Review: A type of research that gathers and organizes all the studies available on a specific topic to see what we already know, where the gaps are, and how future research could address them.
Genetic Categorization Analysis: A research method used to organize and classify genetic variants (changes or mutations in DNA) into meaningful groups based on their characteristics, functions, or associations with specific traits or conditions.
When I analyzed the genetic data from all the studies, clear patterns began to emerge for different types of ovulatory dysfunction. Here's a simplified summary of what I found:
What makes these findings important is that each category of ovulatory dysfunction is tied to different types of genes with specific roles in regulating ovulation.
Recognizing these differences could eventually help doctors design treatments that are more targeted — addressing the root cause rather than applying a one‑size‑fits‑all approach. This could mean more effective therapies, fewer unsuccessful treatment cycles, and a shorter path to pregnancy for many patients.

While this research isn’t something that can be directly applied in the clinic yet, it represents an important step toward more personalized fertility care. Think of it as building the foundation for tools and treatments that could one day make a real difference for patients facing ovulatory disorders.
By compiling all known genetic variants linked to ovulatory dysfunction into one resource, we can push this research forward and identify new ways to individualize treatment plans for patients. The following is a brief glimpse into what this work can accomplish:
This comprehensive reference helps scientists identify patterns that might be missed in smaller, isolated studies, accelerating the pace of discovery.
In the future, patients with unexplained ovulatory dysfunction may have access to tests that can pinpoint the genetic factors involved in their condition.
Understanding a patient’s unique genetic profile could allow fertility specialists to choose medications, protocols, and interventions that have the highest chance of success for that individual.
Instead of cycling through multiple treatments to see what works, genetic insights could help match patients with the most promising options sooner.
Ultimately, this type of research moves us closer to a future where fertility care is not just reactive, but proactive — informed by each patient’s genetic makeup and designed to give them the best possible chance at success.
From concept to publication, this project took about a year and a half to two years.
One reason for the extended timeline was my choice to publish in an open access journal. It was important to me that anyone, patients, clinicians, and researchers, could access these findings without cost or restriction.
Genetics
is already transforming the way we understand health and disease, and reproductive medicine is no exception. I see a future where a patient’s unique genetic profile can help predict which treatments are most likely to work for them, reducing the need for trial and error and shortening the path to success.
Our patients are my inspiration. When the existing tools fall short, I believe it is our responsibility to keep asking questions until we find better answers. This research is one step in that journey.
