Most non-human mammals have a non-single uterus with separation of horns. Marsupials and rodents have a double uterus (uterus duplex). In other animals (e.g. nematodes), the term 'didelphic' refers to a double genital tract, as opposed to monodelphic, with a single tract.
A bicornuate uterus is an indication for increased surveillance of a pregnancy, though most women with a bicornuate uterus are able to have healthy pregnancies. [1] Women with a bicornuate uterus are at an increased risk of recurrent miscarriage, [2] [10] preterm birth, [2] [11] malpresentation, [2] [12] disruptions to fetal growth, [13] premature rupture of membranes, placenta previa and ...
A hysterosalpingogram is not considered as useful due to the inability of the technique to evaluate the exterior contour of the uterus and distinguish between a bicornuate and septate uterus. In addition, laparoscopy and/or hysteroscopy may be indicated. In some patients the vaginal development may be affected. [citation needed]
Dr. Laura Purdy, chief medical officer at Wisp, a sexual health care group, says that “uterus didelphys is rare,” only accounting for 8% of the congenital anomalies of the female reproductive ...
The superior part of the Müllerian ducts do not fuse and form the left and right fallopian tubes. Disruptions to this stage of development can result in didelphys or bicornuate uteri anomalies. [8] In both didelphys and bicornuate uteri, the non-fusion of the Müllerian ducts results in two distinct uterine cavities.
Cat genetics describes the study of inheritance as it occurs in domestic cats. In feline husbandry it can predict established traits ( phenotypes ) of the offspring of particular crosses. In medical genetics , cat models are occasionally used to discover the function of homologous human disease genes.
The span between precocial and altricial species is particularly broad in the biology of birds. Precocial birds hatch with their eyes open and are covered with downy feathers that are soon replaced by adult-type feathers. [17] Birds of this kind can also swim and run much sooner after hatching than altricial young, such as songbirds. [17]
Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats (large and small), hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia consisting of "dog-like" carnivorans (includes Canoidea).
