If indeed 60-70% of all women in the world get a niche after a cesarean section, [3] many women don't know they have a niche, got pregnant and never experienced any trouble during pregnancy. The worst-case scenario of having a niche is the chance of a uterine rupture. A uterine rupture means that the wall of the uterus, at the place of the ...
Uterine contractions are sometimes painful and comfort can be provided by suggesting different positions. Walking around, with assistance, can decrease pain. Since uterine cramping may become more painful during breastfeeding, medications can be given half an hour before nursing.
Uterine Compression of IVC and Pelvic Veins. Displacement of PMI by Uterus. Uterine enlargement beyond 20 weeks' size can compress the inferior vena cava, which can markedly decrease the return of blood into the heart or preload. As a result, healthy pregnancy patients in a supine position or prolonged standing can experience symptoms of ...
Implantation bleeding occurs between 7 and 14 days after fertilization, [57] and is a small amount of light vaginal bleeding or spotting that can occur in early pregnancy due to the blastocyst penetrating the lining of the uterus during implantation.
The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.
The uterus and endometrium was for a long time thought to be sterile. The cervical plug of mucosa was seen to prevent the entry of any microorganisms ascending from the vagina. In the 1980s this view was challenged when it was shown that uterine infections could arise from weaknesses in the barrier of the cervical plug.
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.
Image showing trophoblast differentiated into the two layers of cytotrophoblast and syncytiotrophoblast during implantation. It is the outer layer of the trophoblasts and actively invades the uterine wall, during implantation, rupturing maternal capillaries and thus establishing an interface between maternal blood and embryonic extracellular fluid, facilitating passive exchange of material ...
