Individuals diagnosed with cancer who have not yet begun chemotherapy or radiotherapy can benefit from oocyte cryopreservation. [3] Chemotherapy and radiotherapy are toxic to oocytes, reducing the number of viable eggs. In these cases, egg freezing may be used to preserve eggs. [clarification needed] [citation needed]
Transvaginal oocyte retrieval (TVOR), also referred to as oocyte retrieval (OCR), is a technique used in in vitro fertilization (IVF) in order to remove oocytes from an ovary, enabling fertilization outside the body. [1]
Intracytoplasmic sperm injection (ICSI / ˈ ɪ k s i / IK-see) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg. This technique is used in order to prepare the gametes for the obtention of embryos that may be transferred to a maternal uterus.
Xenopus egg extract is a lysate that is prepared by crushing the eggs of the African clawed frog Xenopus laevis. It offers a powerful cell-free (or in vitro ) system for studying various cell biological processes, including cell cycle progression, nuclear transport , DNA replication and chromosome segregation .
It takes, on average, four to six weeks to complete a cycle of GIFT. First, the woman must take a fertility drug to stimulate egg production in the ovaries.The doctor will monitor the growth of the ovarian follicles, and once they are mature, the woman will be injected with human chorionic gonadotropin (hCG).
Premedication is using medication before some other therapy (usually surgery or chemotherapy) to prepare for that forthcoming therapy.Typical examples include premedicating with a sedative or analgesic before surgery; using prophylactic (preventive) antibiotics before surgery; and using antiemetics or antihistamines before chemotherapy.
Egg donation is the process by which a woman donates eggs to enable another woman to conceive as part of an assisted reproduction treatment or for biomedical research. For assisted reproduction purposes, egg donation typically involves in vitro fertilization technology, with the eggs being fertilized in the laboratory; more rarely, unfertilized eggs may be frozen and stored for later use.
A transvaginal oocyte retrieval is then performed at a time usually between 34 and 36 hours after hCG injection, that is, shortly before when the follicles would rupture. A retrieval at 36 hours after final maturation induction appears to result in optimal embryo quality and pregnancy outcomes. [ 9 ]
