Closed Studies

RADfertility has participated in a variety of research studies over the years. While these studies are no longer active or seeking participants, we are proud to have contributed to them and help advance the field of fertility care.

Closed Research Studies

Listed below are research studies that RADfertility has participated in over the years.

CLOSED - FemaSeed Clinical Study

Women’s health experts at RADfertility are researching a new intrauterine insemination procedure.

You may be eligible for this study if: 

  • You are a female and between the ages of 19 – 40.
  • You do not have an infertility factor, including blocked fallopian tubes, or uterine or ovarian issues.
  • Your male partner has male infertility.

CLOSED - The EMPOWER Clinical Study

Approximately 1 out of 10 women have endometriosis. However, it may take 10 years for the average woman to receive a diagnosis. To us, this is unacceptable.

Join other women in helping us find a better way!

Earlier diagnosis of endometriosis is associated with better treatment outcomes and improved quality of life. The purpose of the EMPOWER Study is to evaluate a new investigational test which may be able to detect endometriosis.

If you are scheduled for a diagnostic laparoscopy for suspected endometriosis you may be eligible to participate.

Participants will receive compensation in appreciation for providing a blood and saliva sample and completing two brief questionnaires.

RADfertility is currently seeking patients to participate in a research study by donating a blood sample that will help evaluate a test that measures Anti-Müllerian hormone (AMH). AMH is a naturally occurring hormone found in both men and women. In women, AMH, is related to the reproductive cycle and the ability to get pregnant, and may help identify women who may have problems getting pregnant because of poor ovarian response.

Eligible participants will be compensated as a result of their volunteer participation in this study.

If you are currently planning to undergo your 1st, 2nd, or 3rd cycle of ovarian stimulation for IVF, you may be eligible to participate in this research study if you meet the following eligibility:

  • You are between the ages of 21 and 45 years old.
  • You have regular menstual cycles (between 21 and 35 days).
  • You have both of your ovaries.
  • You are not currently on oral contraceptives.
  • You do not have confirmed PCOS.
  • You have not had any ovarian surgery within the last year.
  • You have not recently had drug or radiation treatment for cancer.
  • You are not currently pregnant
  • You are willing to provide a blood sample according to the research study.
CLOSED - University of Delaware Fertility and Reproductive Health Knowledge Research Study

The purpose of this study is to examine fertility knowledge in young adults.

You may be eligible to participate if you are:

  • Between the ages of 18-24
  • Have at least a high school diploma or equivalent/GED
  • Have no history of pregnancy

RADfertility is currently seeking women to participate in a research study by donating a blood sample that will help to evaluate a new laboratory test that measures Anti-Müllerian hormone (AMH). AMH is present in all individuals and has been shown to be important in assessing fertility.

You may be eligible for this study if you:

  • Are a female between the ages of 22 and 45

CLOSED - Endometriosis & Pelvic Pain Center Observational Study

RADfertility is currently seeking new patients to participate in an Endometriosis & Pelvic Pain Center Observational Study. This study will describe historic, current, and evolving treatment pathways, treatments, and interventions in women with a suspected or confirmed diagnosis of endometriosis in order to better understand the impact of early intervention on the disease or its symptoms. Length of treatment is dependent on standard of care treatment provided and all study information will be collected during routine standard of care visits.

Please note the study is not open to current or past patients at this time. There are no study medications associated with this research trial. Your plan of care remains the same if you are a participant in the study or not.

You may be eligible to participate if you:

  • are of reproductive age (between their first menstrual cycle and before onset of menopause).
  • have experienced chronic pelvic pain (CPP) and/or dysmenorrhea (DYS) for at least 6 months prior to enrollment without symptom improvement with non-steroidal anti-inflammatory drugs (NSAIDs) or hormone/medical treatment.
  • are a woman with suspected or confirmed endometriosis (EM) at time of enrollment.
  • are a woman with CPP and/or DYS impacting daily activities as determined by their treating physician.
  • are able to read, understand and respond to patient questionnaires.

"I feel so lucky to have found RADfertility. I tried two other clinics before I expanded my search and found RADfertility. I drive an hour each way to go to them but I don’t regret a thing. They are so caring and so professional. Every time I message them they respond quickly. Every time I see them they have a friendly smile and warm welcome. They explain everything so well and I never feel lost in the process as I did elsewhere. They also took the time to figure out what was wrong. Other clinics threw up their hands, said 'I don’t know' and pushed me to try IVF."



"Dr. Feinberg and the entire staff at RADfertility are absolutely amazing. The receptionists, coordinators, nurses, and lab staff are compassionate, caring, and straight forward. I’ve had a 12-year infertility journey and I’ve tried other clinics but RADfertility was the only one I felt at ease with. They answered any questions that I had and were there any time I needed them. My coordinator, Amy, was the absolute best and always had my back. Dr. Feinberg’s dedication to his patients is incredible. You are not just a number there, you are a person with individualized needs and care."

"The RADfertility team gives you so much emotional support and positivity that it adds to your strength and keeps you focused on the end goal - a healthy and happy baby."

"My journey with RADfertility and Dr. McGuirk started when my husband and I were trying to conceive and were having difficulty. We went to RADfertility, where we met Dr. McGuirk. I always say she changed my life and 'fixed' me. Dr. McGuirk is always learning more about endometriosis and how to help her patients. She’s brilliant and truly cares for you! I’m eternally grateful to her and everyone at RADfertility for their unwavering support, love, and care."

Annette D.


"Every step of our journey was tailored to us. We were treated so respectfully. Every detail was clearly explained and we felt so comfortable. Rhonda Wright was a Godsend and inspiring. I highly recommend this place! I cried when my weekly appointments were done and I 'graduated.'"

Christie B.


"The staff and doctors are amazing. It will feel like home every time you walk in the door. They gifted us with our miracle baby and we couldn’t be happier. I will always recommend RADfertility above all others!"

Shannon M.


"RADfertility's staff has heart and provided me with exceptional health care. I knew I was in good hands and felt like we were in this together. The doctors and nursing staff always answered all of my questions and provided thorough information about all of my options. I am so fortunate and appreciative of the care that I received at RADfertility. They go above and beyond."

Megan L.


"I cannot begin to explain how wonderful RADfertility is. We were frustrated with trying to start a family and it not working for us. The entire team of doctors and nurses made us feel comfortable and hopeful that we would be parents. We experienced so many ups and downs but we never felt like we were on our IVF journey alone, we had our RADfertility team every step of the way. If you're looking for a supportive team on the IVF journey, look no further. RADfertility is the absolute best."

"Dr. Schillings always kept us informed and never gave up on us. She always explained our options and risks with each procedure. She called us personally when there were any issues or sensitive subjects to cover. Dr. Schillings was the first doctor that had answers for us and wanted to help us have our miracle baby!"
