The endometrium is central, echogenic (detectable using ultrasound scanners), and has an average thickness of 6.7 mm. During pregnancy, the glands and blood vessels in the endometrium further increase in size and number.
Women's endometrium contains relaxin, which is an essential component that helps prepare the body for early pregnancy. [21] The endometrium is transformed into decidua during the early pregnancy maintenance procedure. [21] The process known as decidualization occurs when the endometrium changes both physiologically and morphologically in order ...
Decidualization is a process that results in significant changes to cells of the endometrium in preparation for, and during, pregnancy. This includes morphological and functional changes (the decidual reaction) to endometrial stromal cells (ESCs), the presence of decidual white blood cells (leukocytes), and vascular changes to maternal arteries.
During pregnancy the plasma volume increases by 40-50% and the red blood cell volume increases only by 20–30%. [22] These changes occur mostly in the second trimester and prior to 32 weeks gestation. [24] Due to dilution, the net result is a decrease in hematocrit or hemoglobin, which are measures of red blood cell concentration.
[5] [40] IL-6 and FAAH are both crucial for uterine receptivity and together with AEA there is seen to be a link with adequate endometrial thickness that sustains pregnancy. [5] During adhesion the cross-talk is conveyed by receptor-ligand-interactions, both integrin-matrix and proteoglycan ones. Proteoglycan receptors are found on the surface ...
The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1] The uterus is a hormone-responsive sex organ that contains glands in its lining that ...
Different categories of birth attendants may provide support and care during pregnancy and childbirth, although there are important differences across categories based on professional training and skills, practice regulations, and the nature of care delivered. Many of these occupations are highly professionalised, but other roles exist on a ...
The decidua is the modified mucosal lining of the uterus (that is, modified endometrium) that forms every month, in preparation for pregnancy. It is shed off each month when there is no fertilized egg to support. [1] The decidua is under the influence of progesterone. Endometrial cells become highly characteristic.
