Ectogenesis (from the Greek ἐκτός, "outside", and genesis) is the growth of an organism in an artificial environment, [1] outside the body in which it would normally be found, such as the growth of an embryo or fetus outside the mother's body, or the growth of bacteria outside the body of a host. [2]
Scientists in Israel have created a model of a human embryo from stem cells in the laboratory, without using sperm, eggs or a womb, offering a unique glimpse into the early stages of embryonic ...
Biology, being the study of cellular life, addresses reproduction in terms of growth and cellular division (i.e., binary fission, mitosis and meiosis); however, the science of artificial reproduction is not restricted by the mirroring of these natural processes.The science of artificial reproduction is actually transcending the natural forms, and natural rules, of reproduction.
To achieve this, he first developed a technique for extended culturing mouse embryos outside the uterus (ex utero) in 2021 capturing development from before gastrulation until late organogenesis outside the uterus, [7] [8] subsequently applying his technique for making the first synthetic complete embryo models of mice in 2022, [5] [9] [10] and ...
That cell, known as a polar body, gives the egg the genetic information it would normally get from sperm. The cell starts dividing and that leads to the creation of an embryo.
The "embryos" grew placentas and organs and could be used for research. We're still a long way before we can make humans embryos that way. In world first, artificial mouse 'embryos' were grown ...
Figure from a 2017 Nature Communications paper describing an extra-uterine life support system, or "biobag", used to grow lamb fetuses. [1]An artificial womb or artificial uterus is a device that would allow for extracorporeal pregnancy, [2] by growing a fetus outside the body of an organism that would normally carry the fetus to term.

Cytoplasmic transfer is the technique in which the contents of a fertile egg from a donor are injected into the infertile egg of the patient along with the sperm. Egg donors are resources for women with no eggs due to surgery, chemotherapy, or genetic causes; or with poor egg quality, previously unsuccessful IVF cycles or advanced maternal age ...
