Ovarian tissue autotransplantation may pose a risk of cancer recurrence in patients with colorectal, gastric and endometrial cancer. [8] However, no metastases have been detected in ovarian tissue from lymphoma and breast cancer patients who have been undergoing ovarian tissue cryopreseration. [8]
Oocyte cryopreservation is a procedure to preserve a woman's eggs . The technique is often used to delay pregnancy . At the time pregnancy is desired, the eggs can be thawed, fertilized, and transferred to the uterus as embryos .
Surgical extraction of ovarian tissue for cryopreservation. [25] Can be carried out before and after puberty. [24] No sperm necessary at time of retrieval. [25] Clinically available. [25] Don't need to halt GAHT. [24] Cryopreservation of either an ovarian cortex biopsy or the whole ovary, then the thawing and maturation of the follicles at a ...
TVOR is typically performed after ovarian hyperstimulation, where oocytes are pharmacologically stimulated to mature. When the ovarian follicles have reached a certain degree of development, induction of final oocyte maturation is performed, generally by an intramuscular or subcutaneous injection of human chorionic gonadotropin (hCG). [10]
An artificial ovary is a potential fertility preservation treatment that aims to mimic the function of the natural ovary. Conventional fertility preservation for females involves oocyte cryopreservation or ovarian tissue cryopreservation. However, there are drawbacks to these treatments.
Cryopreservation or cryoconservation is a process where biological material - cells, tissues, or organs - are frozen to preserve the material for an extended period of time. [1] At low temperatures (typically −80 °C (−112 °F) or −196 °C (−321 °F) using liquid nitrogen ) any cell metabolism which might cause damage to the biological ...
Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.This subject involves procedures such as in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and cryopreservation of gametes and embryos, and the use of fertility medication.
Semen, embryos, oocytes, somatic cells, nuclear DNA, and other types of biomaterial such as blood and serum can be stored using cryopreservation, in order to preserve genetic materials. [ 3 ] [ 4 ] The primary benefit of cryoconservation is the ability to save germplasms for extended periods of time, therefore maintaining the genetic diversity ...
