A surgical technique has been established for orthotopic transplantation of ovarian tissue in newly hatched chickens. In these trials survivability of the chicks after surgical manipulation was 100%. The size and orientation of the ovary at 2 wk of age suggested that the graft was attached and had undergone development. This technique should allow the development of a cryopreservation protocol ...

Abstract Background After ovarian tissue transplantation, ischemia-reperfusion injury and free radicals cause follicle depletion apoptosis. Therefore, the use of antioxidants to reduce production is an important method address consequences injury. Resveratrol a natural active polyphenol compound with anti-inflammatory, antitumor, strong antioxidant anti-free radical properties. The aim this stu...

Reduced fertility is one clinical manifestation among other well known Fanconi anemia features. Most recipients of allogeneic hematopoietic stem cell transplantation suffer from secondary infertility owing to gonadal damage from myeloablative conditioning. In order to evaluate the rate of pregnancy in Fanconi anemia transplanted patients, we performed a retrospective analysis of female patients...

As the efficacies of anticancer therapies were increase and quite efficient early diagnoses have been taken place in gynecological cancer, increased long-term survival of cancer patients and long-term complications of anticancer treatments are being encountered. The lost of ovarian reserve or function due to gonadal toxicity is the major problem that mainly focused. A wide range of new fertilit...

BACKGROUND Despite interest in ovarian tissue transplantation (OTT) as a promising procedure for fertility preservation, to date, no precise data are available about its effectiveness. We systematically reviewed reproductive function after OTT for fertility preservation in women at high risk of premature ovarian failure (POF). METHODS We searched the MEDLINE, EMBASE, Cochrane Systematic Revie...

PURPOSE Cancer treatments for young women can permanently or temporarily affect fertility. The purpose of this retrospective analysis was to present the clinical experience and ethical considerations of fertility preservation in female oncology patients in a tertiary gynaecological department. METHODS Since 2002, in 37 patients fertility preservation was performed according to an institutiona...

Long-term (>7 years) duration of function of ovarian cortical tissue grafts in three patients who have had several successful pregnancies is encouraging and requires us to carefully examine the risk benefit analysis of this technique for our future patients. However, the success rate for ovarian cryopreservation is unclear as the denominator (the number of women in whom frozen-thawed ovarian ti...

A surgical procedure was developed for autoplastic grafting of the ovary into the splenic circulation. The ovarian transplant is joined to the spleen by an attached piece of oviduct and uterus. Direct arterial connections to the graft are maintained throughout the procedure; there is no direct contact of splenic and ovarian tissue. Transplantation of the left utero-tubo-ovarian segment and remo...

From December 2000 until 2010, the researchers at Royan Institute conducted a wide range of investigations on ovarian tissue cryopreservation with the intent to provide fertility pres- ervation to cancer patients that were considered to be candidates for these services. In 2010, Royan Institute established the Royan Human Ovarian Tissue Bank as a subgroup of the Embryology Department. Since its...
