Filter by:While most of the children spontaneously recover menstruation or experienced normal puberty after chemotherapy, their ovarian reserve may be impaired by treatment inducing future infertility. Fertility preservation is currently proposed for selected prepubertal patients with a high risk of premature ovarian failure after treatment (mostly conditioning regimen for bone marrow transplantation). For patients with low or moderate risks, counselling is very difficult and no fertility preservation procedure is usually proposed for these patients as no marker of the ovarian reserve has been validated in this young population to assess the individual risk. The primary objective of the study is to prevent long-term treatment-related infertility by detecting the young patients who normally progressed to menarche but have a reduced ovarian reserve. These patients may benefit from particular follow-up and fertility preservation procedure.
For prepubertal patients, cryopreservation of testicular tissue is the only option available to preserve their fertility before cancer treatment. But testicular autograft raises the issue of the risk of reintroduction of potentially malignant cells. The aim of our study is to develop a specific and sensitive method for residual disease detection in the testicular tissue from patients treated for a solid tumor during infancy, whose fertility may have been compromised by treatments and who benefited of testicular tissue cryopreservation.

The specific aim of this study is to further develop methods of oocyte cryopreservation and evaluate their impact on reproductive outcomes.
The purpose of this study is to evaluate the clinical pregnancy rate per embryo transfer in oocytes recipients obtained after ovarian stimulation during the luteal phase of oocytes donors . This study will be performed in egg recipients and donors but this type of treatment is meant to be implemented in fertility preservation patients
The study hopes to contribute to the development of technologies of ovarian tissue freezing-thawing and in vitro maturation of immature eggs such that a person at risk for premature ovarian failure might be able to conceive a genetically related child.
Vitrification is a method of cryopreserving tissue for future use. It is widely used to preserve extra, good quality embryos generated from infertility treatments. It is becoming popular for the preservation of oocytes (eggs) as well, but is still considered investigational in this respect. The purpose of this study is to provide egg freezing for patients desiring fertility preservation. Although commonly used in clinics around the world, it should be offered as an IRB approved study procedure until it is no longer considered investigational by the American Society of Reproductive Medicine.
Chemotherapy drugs like alkylating agents are frequently used in various combined regimens to treat neoplastic and benign diseases. These drugs are definitely associated with premature ovarian failure (POF), resulting in an important decrease of the long-term quality of life and an increase of morbidity. A recent study showed that the patients treated by alkylating agents had a 4.52 fold higher risk to lose their ovarian function compared with those who were treated by other agents. The rate of POF after treatment ranged from 40 to 80%, according to the age of the patients and the total doses administered. Young women who experience POF have to face with the prospects of infertility and to consider years of hormonal replacement therapy. The possibility of minimizing gonadal damage by administering of protective therapy during chemotherapy represents an attractive option for these patients. The aim of this study is to evaluate the protective effect on the ovarian function of the gonadotropin-releasing hormone agonist (GnRha) administered concomitantly to alkylating agents. Preliminary data in the literature on animals (rat and monkeys) are promising. Data in human are, however, highly controversial.
we will perform xenotransplantation and in vitro culture of ovarian tissue from patients undergoing ovarian cortex cryopreservation.
The purpose of this study is to determine whether gonadotropin releasing hormone agonists (medical therapy) will protect against ovarian failure in reproductive aged women undergoing sterilizing chemotherapy.
