Embryo cryopreservation is useful for leftover embryos after a cycle of in vitro fertilisation, as patients who fail to conceive may become pregnant using such embryos without having to go through a full IVF cycle. Or, if pregnancy occurred, they could return later for another pregnancy.
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. Many studies have suggested infertility problems as germ cell deterioration related to aging. [1]
Cryopreservation for embryos is used for embryo storage, e.g., when IVF has resulted in more embryos than is currently needed. One pregnancy and resulting healthy birth has been reported from an embryo stored for 27 years, after the successful pregnancy of an embryo from the same batch three years earlier. [39]
In 2003, after freeze-thawing, orthotopic autotransplantation of ovarian cortical tissue was done by laparoscopy and five months after reimplantation regular ovulatory cycles were reinitiated. Eleven months after re-implantation a viable intrauterine pregnancy was confirmed, which resulted in the delivery of a healthy baby.
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]
Conceiving a baby using a frozen embryo may raise the mother’s risk of high blood pressure disorders by up to 74%, new research suggests. The findings, published in the journal Hypertension also ...

The same study found that, of 65 patients referred to the program, 28% declined to undergo embryo, oocyte, or tissue cryopreservation. 9% were found not to be eligible for medical reasons. Of the remaining 41 patients, 85% chose to cryopreserve embryos, 10% chose to cryopreserve oocytes, and 5% chose to undergo ovarian tissue freezing. [9]
