  2. Embryo cryopreservation - Wikipedia

    en.wikipedia.org/wiki/Embryo_cryopreservation

    The cryopreservation of embryos was first successfully attempted in 1984 in the case of Zoe Leyland, the first baby to be born from a frozen embryo. [16] In Zoe's case, the embryo had been frozen for two months, but since the inception of the practice of cryopreservation after successful IVF, embryos have successfully survived in ...

  3. Oocyte cryopreservation - Wikipedia

    en.wikipedia.org/wiki/Oocyte_cryopreservation

    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]

  4. Cryopreservation - Wikipedia

    en.wikipedia.org/wiki/Cryopreservation

    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]

  5. Cryoconservation of animal genetic resources - Wikipedia

    en.wikipedia.org/wiki/Cryoconservation_of_animal...

    In cattle, usually 10 or more embryos are removed from the flushing process. In order to flush the uterus, a technician will first seal off the female's cervix and add fluid, which allows the ovum to be flushed out of the uterine horns and into a cylinder for analysis. This process typically takes 30 minutes or less. [30]

  6. Products of conception - Wikipedia

    Gestational sac 15-35mm, embryo smaller than 25mm (corresponding to between 7 and 9+0 weeks of gestational age): Medication is recommended. Surgery or expectant management may be considered. Gestational sac smaller than 15-20mm, corresponding to a gestational age of less than 7 weeks: Expectant management or medication is preferable.

  7. Cryobiology - Wikipedia

    en.wikipedia.org/wiki/Cryobiology

    At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.

  8. Gestation - Wikipedia

    en.wikipedia.org/wiki/Gestation

    Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). [1] It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. [2]

  9. In vitro fertilisation - Wikipedia

    en.wikipedia.org/wiki/In_vitro_fertilisation

    In vitro fertilisation (IVF) is a process of fertilisation in which an egg is combined with sperm in vitro ("in glass"). The process involves monitoring and stimulating a woman's ovulatory process, then removing an ovum or ova (egg or eggs) from her ovaries and enabling a man's sperm to fertilise them in a culture medium in a laboratory.
