The Coloroda Foundation for Fertility Research is a collaborative of researchers doing ongoing groundbreaking research in this field. We share findings with reproductive medical communities around the world. We are the only place that combines the resources, the passion and the belief that progress can be made in the fight against infertility.

CFFFR is conducting the kind of research responsible for advancing reproductive technology, which ultimately gives couples a real chance at having children of their own. That’s why supporting our research is the most important step you can take in the fight to end infertility.

Your dollars go to work right away. Our organization raises money and distributes it immediately to our research team, so we can begin to fulfill the dreams of hopeful parents everywhere. 

From the Laboratory to the Clinic

Research in Practice

The research began at CFFFR in 2005 and in May 2007, the National Foundation for Fertility Research (NFFR) and the Colorado Center for Reproductive Medicine (CCRM) began the world's first Comprehensive Chromosomal Screening (CCS) clinical study looking at all 23 pairs of chromosomes in a few cells removed from an embryo on day 5 of development. The goal of CCS is to only transfer embryos that have the correct number of chromosomes, thus increasing the likelihood of a successful outcome. Results show significantly higher pregnancy rates and lower miscarriage rates when compared to IVF without CCS, especially in women 38-42 years of age. Our findings are published in international peer reviewed journals to share with clinics and organizations around the world.

Ongoing research preformed by the National Foundation for Fertility Research is a valuable asset to couples struggling to conceive from Colorado to across the globe.



Tracy, Denver

“Obstacles were nothing new to my family. As a military couple living oceans apart, our ability to conceive was yet another challenge. Today, my husband and I are the proud parents of two boys.”




A few years ago, my husband and I began seeking fertility treatment. Now, we have a 15-month-old son, Lucas. Lucas is a funny, active and healthy toddler who always makes me laugh. He is such a little character and is the light of my life. In great part, I have NFFR to thank for this blessing. The hard work and research they do in the field of fertility treatment helped bring this amazing child into my life.

If every couple with children tried to imagine life without them, then they would realize the void felt by couples with fertility problems. This is why NFFR is so important. Their research makes families, and everyone should have the opportunity to be blessed with a family.



Ethan & Mark

We got married later in life but still wanted to build a family together. There were many challenges we had not anticipated. Regular testing from my doctor gave us no answers, but a coworker told us about the research being done in fertility treatment and where we could turn for answers. We began seeking treatment in 2000, and we are now blessed with two boys, Ethan, 7, and Mark, 3.

The most important thing we can tell other couples seeking fertility treatment is not to give up hope. The work being done by NFFR helped us fulfill our dream, and it’s helping couples everywhere create the magic of family. I give thanks every single day for my children and know how lucky we are to have this family. As long as NFFR keeps learning and researching, the dream of having a family is alive.



Hannah & Jacob

My wife and I didn’t seem to have a problem getting pregnant, it was staying pregnant that was the issue — the pregnancies terminated within three months. We had convinced ourselves that we would never be able to have children, which was heartbreaking.

We felt hope was lost, but with the advances in fertility research we decided to try again. After a number of tests, it was discovered that the miscarriages were more than likely due to chromosomal abnormalities. We went through an in vitro fertilization cycle and chromosomal analysis of the embryos. Of the nine embryos that fertilized, only five made it to the genetic testing stage. Of those five, only one was genetically normal. We transferred that one embryo and hoped for the best.

Lo and behold the pregnancy took, and not quite nine months later we welcomed a healthy baby girl, Hannah, into our lives. Hannah now has a younger brother, Jacob, whose birth was also made possible through years of fertility research.




The joy a couple experiences as they hold their child for the first time inspires the work we do every day. Only recently has infertility been recognized and classified as a real disease that needs dedicated research and funding to fight it and find a cure.

As part of his legacy, Dr. William Schoolcraft, a world-renowned fertility specialist who has helped couples have children for decades, brought together leading researchers in the field of reproductive medicine to create a nonprofit, publicly-funded, highly motivated research team to fight this disease.

Today, CFFFR is an acclaimed group who continues to make significant progress in reproductive medicine. And we are working hard to continue to fund the research that is helping couples around the world experience the joy of having a baby

CFFR Receives NIH Funding

Published Studies

Blastocysts from Patients with Polycystic Ovaries Exhibit Altered Transcriptome and Secretome

The Role of Proteomics in Defining the Human Embryonic Secretome

Aberration of Blastocyst MicroRNA Expression is Associated with Human Infertility

MicroRNAs are small molecules that are associated with regulating normal cellular function in mammalian cells. They have been shown to be vital during human development. This study describes for the first time that good quality embryos created from infertile patients possess abnormal microRNA profiles. These abnormal embryo microRNA profiles could represent an underlying mechanism that is contributing to the couple’s infertility. 

Blastocyst Gene Expression Correlates with Implantation Potential

Various studies have shown that it’s difficult to predict embryo quality based on appearance alone. In an effort to better understand this, we performed genetic analysis of embryos in a mouse model. We discovered viable embryos that were able to implant and grow into healthy fetuses had a significantly different gene expression pattern, compared to embryos that did not implant or resulted in miscarriage. This work will lead to a better understanding as to which embryos result in successful pregnancies. In addition, this work may improve the way we select embryos for transfer in an IVF cycle. 

Clinical Application of Comprehensive Chromosomal Screening at the Blastocyst Stage

In May 2007, the Colorado Foundation for Fertility Research (CFFR) and the Colorado Center for Reproductive Medicine (CCRM) began the world's first Comprehensive Chromosomal Screening (CCS) study for all 23 pairs of chromosomes in a few cells removed from the embryo on day five of development. The goal of CCS is to reduce the likelihood of implantation failure, miscarriage, and pregnancies affected by these abnormalities by only transferring those embryos that have the correct number of chromosomes.

Current Studies

Oocyte Physiology (Study headed by Dr. Rebecca Krisher)

Oocyte quality impacts early embryonic survival, the establishment and maintenance of pregnancy, fetal development, and even adult disease. Quality, or developmental competence, is acquired during folliculogenesis as the oocyte grows, and during the period of oocyte maturation. Although meiosis, or nuclear maturation, may be completed successfully, there are a variety of other processes occurring within the cytoplasm of the oocyte that are required for complete developmental competence following fertilization. However, the cellular mechanisms that impart oocyte developmental competence are not well understood. It is essential to understand these processes, as they can be influenced by the nutritional status of the mother, ovarian stimulation, and maternal age. For more information about this study 

Protein and Amino Acid Analysis of Spent IVF Culture Media

The purpose of this study will be to perform molecular analysis of spent IVF culture media to identify potential biomarkers linked to viability. Currently, there are no definitive biomarkers for viability in human IVF with embryos selected for transfer based on morphology alone. Our hypothesis is that viable embryos will have a specific molecular profile characterizing their ability to develop, implant and progress to a livebirth. Dishes containing only empty drops of spent culture media would normally be discarded during an IVF cycle after removal of the embryos. However, for this study the spent culture media will be analyzed to generate a molecular profile. These profiles will then be grouped according to the outcome of their IVF cycle allowing for the identification of proteins that may correlate with the successful establishment of a clinical pregnancy. If markers of embryo health are identified by analyzing the spent culture media this could translate into the development of a viability assay that would improve the selection of embryos for transfer increasing the chances for establishment of a successful clinical pregnancy.

Molecular Analysis of Reproductive Tissues/Fluids

The purpose of this study will be to collect and analyze reproductive tissues and/or fluids to gain a better understanding of the causes of human infertility and reproductive associated conditions such as, polycystic ovarian syndrome, recurrent pregnancy loss and endometriosis etc. To date, the molecular mechanisms involved in human reproduction and these conditions are poorly understood. This study will involve the collection of reproductive tissues and/or fluids during routine infertility evaluation, treatment or scheduled reproductive surgery. Samples to be obtained include endometrial biopsies, follicular fluid during IVF oocyte aspiration and uterine fluid at the time of embryo transfer. Surgical procedures would include laproscopic biopsies of endometriosis, ovarian cystectomies, hysterscopic myomectomies, endometrial curettage, etc. The samples will be analyzed for both gene and protein expression profiles to determine the underlying biochemical pathways and cellular function. From a clinical perspective, the identification of these molecular mechanisms could improve patient care and management.

Preimplantation Genetic Diagnosis to Assess Aneuploidy

The purpose of this clinical trial is to determine if testing embryos for chromosomal abnormalities prior to transfer will increase pregnancy rates and/or lower rates of clinical miscarriage. Normally, there are 23 pairs of chromosomes in each human cell, for a total of 46 chromosomes. Each of these chromosomes has a characteristic appearance and is assigned a number or letter. Twenty-three chromosomes usually come from the mother and are contained in the egg, and 23 chromosomes come from the father, derived from the sperm. An abnormal number of chromosomes can result when eggs, sperm or embryos divide incorrectly. Such abnormalities in chromosome number are called aneuploidy. A common example is an extra chromosome number 21 found in Down syndrome. It has been estimated that human embryos fertilized in vitro may contain chromosomal abnormalities in as many as 50% of cases. By removing a single cell/s from the egg or embryo, it is possible to determine the chromosome number. To date, it was only possible to screen for up to 9 chromosomes. However, with this clinical trial new technology allows for the screening of all 23 chromosomes. Thus only embryos with the correct number of all 23 chromosomes are then selected for transfer back into the woman’s uterus.
