Research Priorities
1. Female Fertility Preservation
Fertility preservation includes procedures used to help keep a person's ability to have children. These may give patients with cancer or other rare disorders that affect fertility the opportunity to possibly have biological children in the future, which may also improve their quality of life. Ovarian Tissue Cryopreservation (OTC) is a surgical procedure in which part, or a whole ovary is removed. The tissue, which contains immature eggs, is frozen and stored. Later in life, the tissue may be re-implanted inside the body for future fertility. In December 2019, the American Society of Reproductive Medicine Committee Opinion on fertility preservation in patients undergoing gonadotoxic therapies stated that OTC should be considered an established medical procedure and is no longer considered experimental. However there remain significant gaps in knowledge regarding OTC for fertility preservation in children and adolescents receiving gonadotoxic therapy as the fertility effect of gonadotoxic therapy as well as the fertility benefits of OTC cannot be ascertained until 5 to 30 years after therapy. Even less is known about OTC in patients with diminished ovarian reserve or premature ovarian insufficiency due to causes that are not due to gonadotoxic agents such as chromosomal abnormalities or genetic mutations.
At the NICHD-PAG, we have been involved in research through the Oncofertility Consortium and have had an ovarian tissue cryopreservation (OTC) protocol for girls receiving gonadotoxic therapies (chemotherapy and radiation therapy) at Children's National Hospital since 2012.
We work closely with the Reproductive Endocrinology and Infertility Division and refer patients who qualify to their Evaluation of Women and Men with Endocrine and Reproductive-Related Conditions Protocol that offers oocyte cryopreservation services (Protocol #99-CH-0103: https://clinicalstudies.info.nih.gov/protocoldetails.aspx?id=99-CH-0103&&query=)
Our team at NICHD is involved in several projects which will advance the field of oncofertility and fertility preservation in special populations, such as Turner Syndrome, Galactosemia, adolescent premature ovarian insufficiency.
- NICHD/Oncofertility Ovarian Tissue Slide Image Databank
The purpose is to create a digital ovarian tissue slide image database of H&E-stained ovarian tissue slides. The primary objective of this study is to create a digital slide database with the goal of fostering collaborative research by making the slides accessible to scientists intramurally and extramurally both nationally and internationally. - NICHD Ovarian Tissue Cryopreservation Protocol
The PAG program has developed a protocol for ovarian tissue cryopreservation for prepubertal children with Turner syndrome, classic galactosemia and adolescents with recent premature ovarian insufficiency (POI).- For more information on this study, please visit https://clinicalstudies.info.nih.gov/protocoldetails.aspx?id=000106-CH&&query= and https://clinicaltrials.gov/ct2/show/NCT04948658.
- Research on the Impact of Gonadotoxic Therapy and Fertility Preservation
The NICHD-PAG program is participating in a national clinical database of individuals who underwent ovarian tissue cryopreservation in order to learn about the risks and benefits of OTC - NICHD Ovarian Nomenclature Workshop 2021
Experts in reproductive endocrinology, gynecologic oncology, radiology, pathology, bioinformatics, and ovarian tissue research, met and created workgroups to further delineate ovarian follicle description, tissue ontology, and the 3-D description of the ovary. - Fertility ConcepTS Study
The purpose of this study is to improve our understanding of attitudes of individuals with Turner syndrome (TS) and their parents/guardians towards fertility, fertility preservation and options for building a family by developing and disseminating a fertility attitudes survey of adolescents and young adults (AYA) with TS and their parents/guardians.- For more information on this study, visit https://www.clinicaltrials.gov/ct2/show/NCT05078892?cond=Turner+Syndrome&cntry=US&state=US%3AMD&draw=2&rank=6.

2. Childhood and Adolescent Beginnings of Gynecologic Conditions
Endometriosis is a condition in which tissue similar to the lining of the uterus grows in other places in the body and can cause significant pain. Polycystic Ovary Syndrome (PCOS) is a set of symptoms related to a hormonal imbalance resulting in irregular periods, excessive hair growth, severe acne, infertility which can result in long term consequences including diabetes, metabolic syndrome, and uterine cancer. Lichen sclerosus is a skin condition which has been mostly studies in post-menopausal women but also affects children. All of these conditions begin during the childhood or adolescent period and are associated with significant health problems and impact quality of life. However, the study of these conditions has predominantly been done in adult populations. Pediatric and adolescent population-based studies to evaluate the beginnings of these conditions may elucidate possible early diagnosis and intervention, treatment, and prevention.

Data Collection Study of Pediatric and Adolescent Gynecology Conditions
Endometriosis, PCOS and other PAG conditions will be evaluated and treated through the Data Collection Study of Pediatric and Adolescent Gynecology Conditions.

3. Rare Gynecologic Conditions: Implications for Human Health
The study of rare conditions often can elucidate unique physiology that affect human health and development. We have developed protocols to study several conditions encountered in PAG which are detailed below.
- Database of Pediatric and Adolescent Gynecology Conditions
The overall purpose of this study is to provide medical and surgical management of specific PAG conditions and to gather information over time from large groups of patients within each of diagnosis to help improve our understanding of these conditions.- For more information on this study, visit https://clinicalstudies.info.nih.gov/ProtocolDetails.aspx?id=2020-CH-0126.
- Natural History Study of Individuals with Androgen Insensitivity Syndrome (AIS)

4. Rare Diseases with Associated Gynecologic Conditions
Individuals with rare diseases often have significant gynecologic impact from their underlying conditions. Gynecologic conditions throughout the reproductive span in individuals with rare conditions will be evaluated in Data Collection Study of Pediatric and Adolescent Gynecology Conditions listed above.
Examples of collaboration with other NIH teams in research on gynecologic conditions in individuals with rare conditions:
- Fibrous dysplasia/McCune Albright Syndrome (FD/MAS)- Michael Collins, MD, NIDCR- MAS is caused by a somatic mutation that can be present in the ovary and cause spontaneous activation of ovarian function and precocious puberty. We conducted a phone interview of all women in the FD/MAS study and asked about OB/GYN history. Currently we are working with the FD/MAS investigators to evaluate bleeding and pain symptoms after menarche, obstetrical outcomes, fertility, and age of menopause.

- Congenital Adrenal Hyperplasia (CAH)- Deborah Merke, MD, MS- Women with excess androgen conditions have significant gynecologic impact from their underlying endocrine disorder. We have conducted a case control study of sexual function and quality of life in women with CAH compared to age, race, and marital status matched controls. Based on these results we are evaluating interventional studies to improve sexual function.
