Fertility preservation has become an issue of great importance in female cancer patients due to increasing survival rates and delayed childbearing. It is an emerging challenge for physicians, cause of several related issues (multidisciplinary approach, doctor-patient communication, ethical, religious and legal problems) and many unresolved questions. This review aims to update the latest literature data, summarizing the effects of cancer treatments on female fertility and the various options currently available to offer cancer patients the opportunity of future pregnancies. Many strategies exist for fertility preservation in young women and they should be assessed according to the patient's age, type of cancer, partner status and time available. Some techniques are well established, others are still experimental. The established methods include embryo cryopreservation, transposition of ovaries prior to radiation therapy, radiation shielding of gonads and conservative surgical approaches. The experimental methods include oocyte cryopreservation, in vitro maturation of oocytes, ovarian tissue cryopreservation and transplantation, and ovarian suppression. Improvement of these techniques as well as better characterization of their success rates and risks, await further investigation. Oocytes donation and gestational surrogacy represent the last options. Thus, the care of these patients is challenging, complex and requires a multidisciplinary approach. A close collaboration between Oncologists, Specialists in Reproductive Medicine, Gynecologic Oncologists and Endocrinologists is crucial for always offering the best possible option.

Tamoxifen, a common adjuvant therapy for hormone receptor-positive breast cancer, is associated with an increased risk of endometrial pathologies, such as hyperplasia, polyps, and carcinoma. This study investigates rapamycin, an mTOR inhibitor, as a potential novel strategy for preventing tamoxifen-induced endometrial proliferation. This in vitro study utilised endometrial stromal cells isolated from infertile women.

Background: In the cryopreservation process, rooster spermatozoa are vastly sensitive to reactive oxygen species (ROS). This study aimed to investigate the effects of Lake extender supplemented via Cysteamine (CYS) on the quality and fertility characteristics of rooster semen during the cryopreservation process.
Methods: Semen samples were collected from 10 proved Ross-308 roosters, diluted and cryopreserved in the Lake extender which contained 0, 1, 2, 4, and 8 mM of CYS (C-0, C-1, C-2, C-4, and C-8, respectively).

The surgical management of cancer patients wishing fertility preservation is multidisciplinary, involving surgeon, anesthetist, hematologist, and nursing and laboratory staff. Many oncology patients have a multitude of medical or surgical conditions that require careful planning of all therapy including surgical removal of reproductive material, either oocytes or ovarian tissue. The significant risks related to either transvaginal or abdominal surgery should be discussed and documented and the final decision to proceed must be balanced against the risks, including death.

Data collection from all referred patients allows continuous learning and improvement of services. Patient safety and return for cancer therapy takes priority in all oncofertility services. In certain cases, the intervention for female patients is contraindicated and, aside from extensive counseling, alternative methods of preserving fertility should be explored.
