Engineered Uterus
An engineered uterus is an organ cultured or tissue engineered uterus in vitro. Organ culture is the cultivation of either whole organs or parts of organs in vitro. Using engineered uterus is not yet tried to human, but successful childbirth in rabbit was observed. Ethics The use of a bioengineered uterus may be regarded as more ethical than the uterus transplant of donated uterus.

Tissue Engineering
Tissue engineering is a biomedical engineering discipline that uses a combination of cells, engineering, materials methods, and suitable biochemical and physicochemical factors to restore, maintain, improve, or replace different types of biological tissues. Tissue engineering often involves the use of cells placed on tissue scaffolds in the formation of new viable tissue for a medical purpose, but is not limited to applications involving cells and tissue scaffolds. While it was once categorized as a sub-field of biomaterials, having grown in scope and importance, it can be considered as a field of its own. While most definitions of tissue engineering cover a broad range of applications, in practice, the term is closely associated with applications that repair or replace portions of or whole tissues (i.e. organs, bone, cartilage, blood vessels, bladder, skin, muscle etc.). Often, the tissues involved require certain mechanical and structural properties for proper functioning. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterus
The uterus (from Latin ''uterus'', : uteri or uteruses) or womb () is the hollow organ, organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic development, embryonic and prenatal development, fetal development of one or more Fertilized egg, fertilized eggs until birth. The uterus is a hormone-responsive sex organ that contains uterine gland, glands in its endometrium, lining that secrete uterine milk for embryonic nourishment. (The term ''uterus'' is also applied to analogous structures in some non-mammalian animals.) In humans, the lower end of the uterus is a narrow part known as the Uterine isthmus, isthmus that connects to the cervix, the anterior gateway leading to the vagina. The upper end, the body of the uterus, is connected to the fallopian tubes at the uterine horns; the rounded part, the fundus, is above the openings to the fallopian tubes. The connection of the uterine cavity with a fallopian tube is called the utero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Childbirth
Childbirth, also known as labour, parturition and delivery, is the completion of pregnancy, where one or more Fetus, fetuses exits the Womb, internal environment of the mother via vaginal delivery or caesarean section and becomes a newborn to the world. In 2019, there were about 140.11 million human births globally. In Developed country, developed countries, most deliveries occur in hospitals, while in Developing country, developing countries most are home births. The most common childbirth method worldwide is vaginal delivery. It involves four stages of labour: the cervical effacement, shortening and Cervical dilation, opening of the cervix during the first stage, descent and birth of the baby during the second, the delivery of the placenta during the third, and the recovery of the mother and infant during the fourth stage, which is referred to as the Postpartum period, postpartum. The first stage is characterised by abdominal cramping or also back pain in the case of B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabbit
Rabbits are small mammals in the family Leporidae (which also includes the hares), which is in the order Lagomorpha (which also includes pikas). They are familiar throughout the world as a small herbivore, a prey animal, a domesticated form of livestock, and a pet, having a widespread effect on ecologies and cultures. The most widespread rabbit genera are '' Oryctolagus'' and '' Sylvilagus''. The former, ''Oryctolagus'', includes the European rabbit, ''Oryctolagus cuniculus'', which is the ancestor of the hundreds of breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, ''Sylvilagus'', includes over 13 wild rabbit species, among them the cottontails and tapetis. Wild rabbits not included in ''Oryctolagus'' and ''Sylvilagus'' include several species of limited distribution, including the pygmy rabbit, volcano rabbit, and Sumatran striped rabbit. Rabbits are a paraphyletic grouping, and do not constitute a clade, as ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uterus Transplant
A uterus transplantation is a surgical procedure that transplants a healthy uterus into someone whose uterus is absent, or diseased. As part of normal sexual reproduction, a diseased or absent uterus prevents a pregnancy. This form of infertility is known as ''absolute uterine factor infertility'' for which a uterine transplant may be able treat. History Studies In 1896, Emil Knauer, a 29-year-old Austrian working in one of Vienna's gynecological clinics, published the first study of ovarian autotransplantation documenting normal function in a rabbit. This led to the investigation of uterine transplantation in 1918. In 1964 and 1966, Eraslan, Hamernik and Hardy, at the University of Mississippi Medical Center in Jackson, Mississippi, were the first to perform an animal (dog) autotransplantation of the uterus and subsequently deliver a pregnancy from that uterus. In 2010 Diaz-Garcia and co-workers, at Department of Obstetrics and Gynecology, University of Gothenburg in Sweden, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Womb
An artificial womb or artificial uterus is a device that allows for extracorporeal pregnancy, by growing a fetus outside the body of an organism that would normally carry the fetus to term. An artificial uterus, as a replacement organ, could have many applications. It could be used to assist male or female couples in the development of a fetus. This can potentially be performed as a switch from a natural uterus to an artificial uterus, thereby moving the threshold of fetal viability to a much earlier stage of pregnancy. In this sense, it can be regarded as a neonatal incubator with very extended functions. It could also be used for the initiation of fetal development. An artificial uterus could also help make fetal surgery procedures at an early stage an option instead of having to postpone them until term of pregnancy. An artificial uterus or incubator can also serve as a tool for wildlife conservation and de-extinction by eliminating the need for surrogate animals and mass-in ...

Male Pregnancy
Male pregnancy is the incubation of one or more embryos or fetuses by organisms of the male sex in some species. Most species that reproduce by sexual reproduction are heterogamous—females producing larger gametes ( ova) and males producing smaller gametes (sperm). In nearly all animal species that give live birth, offspring are carried by the female until birth, but in fish of the family Syngnathidae ( pipefish, seahorses and the leafy seadragon), males perform that function. In animals Syngnathidae family The fish family Syngnathidae has the unique characteristic of a highly derived form of male brood care referred to as "male pregnancy". The family is highly diverse, containing around 300 different species of fish. Included in Syngnathidae are seahorses, the pipefish, and the weedy and leafy seadragons. The males of some of these species possess a brood pouch on the trunk or tail; in other species, the eggs are merely attached to the male's trunk or tail when t ...

Transgender Pregnancy
Transgender pregnancy is the gestation of one or more embryos or fetuses by transgender people. This is possible for those born with female reproductive systems. However, Gender transition, transition-related treatments may impact fertility. Transgender men and non-binary gender, nonbinary people who are or wish to become pregnant face social, medical, legal, and psychological concerns. As uterus transplantations are currently experimental, and none have successfully been performed on trans woman, trans women, they cannot become pregnant. Trans men Pregnancy is possible for transgender men who retain functioning ovary, ovaries and a uterus, such as in the case of Thomas Beatie. Regardless of prior transgender hormone therapy, hormone replacement therapy (HRT) treatments, the progression of pregnancy and birthing procedures are typically the same as those of cisgender women. Delivery options include conventional methods such as vaginal delivery and cesarean section, and patien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
