• Systematic Review of the Gonadotoxicity and Risk of Infertility of Soft Tissue Sarcoma Chemotherapies in Pre- and Postpubertal Females and Males Juli 12, 2024
  Increasing awareness of gonadotoxicity in cancer treatments and infertility risk is essential for counseling young cancer patients. While fertility preservation options are available in many countries, limited data on gonadotoxicity hinder recommendations, especially for soft tissue cancers. This review, part of the FertiTOX project (www.fertitox.com), organized by FertiPROTEKT (www.fertiprotekt.com), aims to address this knowledge gap […]

• The Australian New Zealand Consortium in Children, Adolescents, and Young Adults Oncofertility action plan Mai 8, 2024
  International and national oncofertility networks, including the US-led Oncofertility Consortium, FertiProtekt, and the Danish Network, have played pivotal roles in advancing the discipline of oncofertility over the last decade. Many other countries lack a shared approach to pediatric oncofertility health service delivery. This study aims to describe baseline oncofertility practices at Australian New Zealand Children's […]

• A Systematic Review of the Gonadotoxicity of Osteosarcoma and Ewing's Sarcoma Chemotherapies in Postpubertal Females and Males April 17, 2024
  Data on gonadotoxicity of chemotherapies are essential to better counsel young females and males about the risk of infertility and to better indicate fertility preservation measures before cancer therapies. However, such data have not recently been reviewed for bone cancer. Therefore, a systematic literature search was conducted considering papers published since 2000. This study is […]

• Evaluation of the Gonadotoxicity of Cancer Therapies to Improve Counseling of Patients About Fertility and Fertility Preservation Measures: Protocol for a Retrospective Systematic Data Analysis and a Prospective Cohort Study März 20, 2024
  CONCLUSIONS: The study can be expected to bridge the data gap regarding the gonadotoxicity of cancer therapies to better counsel patients about their infertility risk and their need to undergo fertility preservation procedures. Initial data are expected to be uploaded on the FertiTOX platform in 2026.

• Indication and implementation of fertility preservation measures in female cancer patients Juni 14, 2023
  The aspects of fertility preservation in women prior to surgical, gonadotoxic or radiation therapy represent a challenging topic in many disciplines and often in an interdisciplinary setting. Within an often short period of time, individual counselling and consideration must be given as to whether fertility-protective measures are useful. The implementation is ultimately decided by the […]

• National oncofertility registries around the globe: a pilot survey Mai 24, 2023
  CONCLUSION: Although oncofertility services are expanding globally, very few countries have well-established official national oncofertility registries. By reviewing such a global landscape, we highlight the urgent need for having a well-established official national oncofertility registry in each country to monitor oncofertility services in a way that best serves patients.

• Determinants of transplantation success with cryopreserved ovarian tissue: data from 196 women of the FertiPROTEKT network Oktober 22, 2022
  STUDY QUESTION: What are the pregnancy and live birth rates for ovarian tissue transplantation and which factors are associated with the success rate?

• Transplantation of cryopreserved ovarian tissue in a series of 285 women: a review of five leading European centers Mai 2, 2021
  The feasibility of freezing and thawing ovarian tissue is nowadays widely documented. However, ovarian tissue transplantation (OTT) is happening at a much slower pace, and clinical experience is somewhat limited. In this review, five European centers present their collective experience of transplanting ovarian tissue in 285 women. The focus is on surgical techniques and OTT […]

• Cryopreservation and Thawing of Human Ovarian Cortex Tissue Slices August 16, 2020
  Cryopreserved ovarian cortex tissue can be used to improve or restore female fertility. It can be used for cancer patients to restore fertility after chemotherapy treatment or for social reasons for women who want to postpone their pregnancy wish. In order to preserve ovarian tissue viability in these cases, the tissue needs to be stored […]

• Motherhood after cancer: fertility and utilisation of fertility-preservation methods Mai 8, 2020
  CONCLUSION: After cancer and gonadotoxic treatment, women's desire to have a child is substantial. In this study, the rate of spontaneous pregnancies and births was 20% 6 years after gonadotoxic therapies. Not every woman, however, has the opportunity to conceive: factors impairing fertility include ongoing cancer treatment or persistent disease, no partner, no menstrual cycle, […]

• Serum anti-Mullerian hormone (AMH) concentration has limited prognostic value for density of primordial and primary follicles, questioning it as an accurate parameter for the ovarian reserve März 8, 2020
  CONCLUSIONS: Serum AMH levels have limited prognostic value for the follicle density and therefore for the real ovarian reserve.

• Ovarian Tissue Transplantation: Experience From Germany and Worldwide Efficacy August 22, 2019
  Extraction of ovarian tissue prior to oncologic therapy and subsequent transplantation is being performed increasingly often to preserve fertility in women. The procedure can be performed at any time of the cycle and, therefore, generally does not lead to any delay in oncological therapy. Success rates with transplantation of cryopreserved ovarian tissue have reached promising […]

• The effect of bpV(HOpic) on in vitro activation of primordial follicles in cultured swine ovarian cortical strips Mai 16, 2019
  The vanadate-derivative dipotassium bisperoxo (5-hydroxy-pyridine-2-carboxylic) oxovanadate (V) (bpV(HOpic)), a pharmacological inhibitor of phosphatase and tensin homolog (PTEN), has been used in ovarian follicle culture systems for activation of follicular growth in vitro and suggested to be responsible for primordial follicle survival through indirect Akt activation. For pig ovarian tissue, it is still not clear which […]

• FertiPROTEKT, Oncofertility Consortium and the Danish Fertility-Preservation Networks - What Can We Learn From Their Experiences? Mai 10, 2019
  Fertility preservation is an increasingly important discipline. It requires close coordination between reproductive medicine specialists, reproductive biologists, and oncologists in various disciplines. In addition, it represents a particular health policy challenge, since fertility-protection measures are to be understood as a treatment for side effects of gonadotoxic treatments and would therefore normally have to be reimbursed […]

• Overnight ovarian tissue transportation for centralized cryobanking: a feasible option Februar 9, 2019
  CONCLUSIONS: Overnight transportation for central cryobanking is a feasible concept that results in high reproducible success rates through standardized professional tissue freezing and storage.

• Fertility preservation: ovarian response to freeze oocytes is not affected by different malignant diseases-an analysis of 992 stimulations Juni 6, 2018
  CONCLUSIONS: As ovarian response is not affected by the type of cancer, ovarian stimulation can be performed with the same oocyte yield in different malignant diseases. However, oocyte yield is reduced if ovarian surgery is required and in older women.

• Clinical Practice Guidelines for Fertility Preservation in Pediatric, Adolescent, and Young Adults with Cancer März 28, 2018
  In recent years, more cancer patients are achieving long-term survival owing to advances in treatment. However, cancer treatment can cause gonadal dysfunction that leads to loss of fertility. Thus, it is important for clinical oncologists to consider fertility preservation in children, adolescents, and young adults with cancer who are expected to have a favorable outcome […]

• Fertility Preservation in Prepubertal und Pubertal Children and Adolescents Februar 9, 2018
  CONCLUSION: In children and adolescents, measures of fertility preservation should be considered in cases of highly gonadotoxic therapies, and appropriate advice should be given by specialists.

• Fertility protection: complications of surgery and results of removal and transplantation of ovarian tissue Dezember 5, 2017
  Fertility-preserving measures are becoming important for patients receiving oncological treatment. One method involves cryopreservation of ovarian tissue and transplanting it when treatment is completed. We report complications resulting from surgical and fertility medicine, and the results of procedures for the removal and transplantation of ovarian tissue carried out within the FertiProtekt network. A survey using […]
