One of the most important concerns cancer survivors face is fertility. Current treatment modalities often result in damage to the reproductive system. Different options have been proposed to preserve the fertility of affected women, and many attempts have been made to improve their chance of childbearing after therapy. Cryopreservation of ovarian tissue and follicles before the onset of cancer treatment and then either transplantation of ovarian tissue or culture of ovarian tissue and individual follicles in vitro is a commonly cited approach...

For patients at risk of premature ovarian failure with cancer treatment, it is an important option to re-implant the ovarian tissue (OT) after cryopreservation to preserve endocrine function and fertility. With this technique, about 30% of pregnancy success rate and about 90 live births have been reported to date. However, there has been no case report of successful in vitro fertilization (IVF) and embryo transfer (ET) with oocytes collected from transplanted cryopreserved OT in Korea. We report a 30-year old woman with rectal cancer who underwent IVF and ET after cryopreserved OT thawing and re-implantation...

OBJECTIVES: To evaluate young women's awareness of ovarian reserve testing and oocyte cryopreservation (OC) and assess how testing ovarian reserve may affect the desire for fertility preservation. METHODS: Three questionnaire-based observational studies were conducted among female students/young professionals 20 years of age and older. The third survey was completed after participants were offered anti-Mullerian hormone (AMH) testing. The main outcomes measured included awareness that OC is available, interest in pursuing fertility preservation, and whether interest would change based on knowledge of declining fertility...

Freezing of ovarian tissue for fertility preservation has been gaining ground as a valid method in recent years. More than 100 children have been born from this procedure worldwide. As a result, many fertility clinics are now implementing this method. However, the practical procedures that need to be mastered to successfully implement the freezing of ovarian tissue are different in many aspects from those normally used in fertility clinics and are not well defined. Furthermore, success is difficult to measure since patients usually do not return for transplantation until several years after freezing, which puts extra emphasis of good quality control and quality assurance measures to secure a transplantation of tissue with surviving follicles that can sustain fertility...

BACKGROUND: Fertility preservation by whole ovary cryopreservation and transplantation (WOCP&TP) with vascular anastomosis requires successful cryopreservation. In this study, we investigated the possibility of restoring ovarian function and natural fertility after WOCP&TP in a premature ovarian insufficiency (POI) rat model. The influence of cryopreservation on the offspring of rats following WOCP&TP was also explored. METHOD: Rats aged 8-10 weeks were used as donors and recipients for allotransplantation...

REVIEW
Sine Berntsen, Anja Pinborg
Increase in success rates with frozen embryo transfer (FET) and reduced risk of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancies has lead to a steady rise in FET. Further, FET is associated with lower risk of prematurity and low birth weight in singletons, when compared with fresh transfer. However, there is a growing concern of increased risk of large for gestational (LGA) and/or macrosomic children after FET. Macrosomic/LGA births have a higher risk of cesarean section, fetal hypoxia and stillbirth...

Cancer survivorship rates have drastically increased due to improved efficacy of oncologic treatments. Consequently, clinical concerns have shifted from solely focusing on survival to quality of life, with fertility preservation as an important consideration. Among fertility preservation strategies for female patients, ovarian tissue cryopreservation and subsequent re-implantation has been the only clinical option available to cancer survivors with cryopreserved tissue. However, follicle atresia post-transplantation and risk of re-introducing malignant cells have prevented this procedure from becoming widely adopted in clinics...

PURPOSE: To assess the attitude towards ovarian tissue and oocyte cryopreservation for non-medical reasons. METHODS: Cross-sectional electronic survey in 248 Swiss women aged 15-35 years, nationally representative for educational level. RESULTS: Most women did not worry about an age-related fertility decline. Two-thirds of women would consider using hormone therapy (HT) for menopausal symptom relief although concerns about side effects and risks were still high...

An ongoing increase in survival rates among young leukemia patients is accompanied by a growing attention to possible long-term complications such as chemotherapy induced ovarian insufficiency and infertility. Therefore, an important element of the management of these patients is fertility preservation, which is challenged by considerations specific for leukemia. Such considerations include prepuberty, poor medical condition on presentation and the need for urgent chemotherapy, all of which may preclude the use of conventional assisted reproductive technologies...

Ovarian tissue removed from a nine year old girl suffering from thalassemia was kept deep- frozen for 14 years before being transplanted back to the now adult woman. Subsequently, she conceived following IVF treatment and delivered a healthy baby where the oocyte derived from the transplanted tissue. This is the first woman worldwide to have a baby where the ovarian tissue was frozen pre-pubertally and expand the therapeutic options for rare genetic diseases like thalassemia and girls who suffer from childhood cancer...

Background: The use of embryo cryopreservation excludes the possible detrimental effects of ovarian stimulation on the endometrium, and higher reproductive outcomes following this policy have been reported. Moreover, gonadotropin-releasing hormone agonist trigger in gonadotropin-releasing hormone (GnRH) antagonist cycles as a substitute for standard human chorionic gonadotropin trigger, minimizes the risk of ovarian hyperstimulation syndrome (OHSS) in fresh as well as frozen embryo transfer cycles (FET)...

Improvements in cancer treatments have increased the chances of survival of young cancer patients, but have given rise to other issues, like premature ovarian insufficiency and infertility. Preservation and subsequent restoration of ovarian function in these patients is now possible thanks to ovarian tissue cryopreservation and transplantation. However, safety concerns about the possible presence of cancerous cells in the tissue to be cryopreserved must be addressed. Indeed, reimplantation of malignant cell-contaminated ovarian tissue could potentially lead to recurrence of the primary disease...

Oocyte vitrification and ovarian tissue cryopreservation are 2 common fertility preservation options. Oocyte vitrification provides the highest yield for women with benign diseases or those seeking fertility preservation for age-related fertility decline. This technique is also indicated for cancer women if cancer treatment can be post-poned. Ovarian tissue cryopreservation has some specific indications. There is indeed no other alternative for fertility preservation in prepubertal girls, adolescents and cancer women in whom cancer treatment cannot be postponed...

Cryopreservation and transplantation of ovarian tissue has proved to restore both endocrine and reproductive functions in cancer patients. However women with a high risk of ovarian involvement cannot undergo ovarian tissue transplantation due to possible recurrence of the disease. Therefore, different teams worldwide are now working on the development of experimental strategies, like the transplantable artificial ovary (TAO), with the noble goal to offer to these patients hope for future conception. This article discusses some essential points for the creation of a TAO and reviews the latest progress made...

Endometriosis is a frequently encountered benign gynecological disease that may be responsible for infertility. Treatment of endometriosis-associated infertility has been investigated using both medical and surgical therapeutic modalities. Therapy has essentially three main objectives: (i) to preserve and improve fertility, (ii) to reduce pain, and (iii) to delay recurrence. The aim of this paper is to focus on fertility preservation in women with severe endometriosis. In ovarian endometriosis-associated infertility, a medico-surgical approach remains the gold standard, but more and more papers are reporting a low ovarian reserve after laparoscopic cystectomy for endometriomas...

Fertility preservation has emerged as a field of growing interest thanks to increasingly effective cancer treatments in women. For young women with good prospects of surviving cancer, fertility preservation counseling before gonadotoxic treatment is imperative to offer them a potential chance of future childbearing. Ovarian tissue cryopreservation and transplantation rises as a strategy for fertility preservation, especially for prepubertal girls, adolescents and women in whom cancer treatment cannot be delayed...
