Traditional obstetric sonograms are done by placing a transducer on the abdomen of the pregnant woman. One variant, transvaginal sonography, is done with a probe placed in the woman's vagina. Transvaginal scans usually provide clearer pictures during early pregnancy and in obese women.
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 gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...
According to a study conducted by Whitcome, et al., lumbar lordosis can increase from an angle of 32 degrees at 0% fetal mass (i.e. non-pregnant women or very early in pregnancy) to 50 degrees at 100% fetal mass (very late in pregnancy). Postpartum, the angle of the lordosis declines and can reach the angle prior to pregnancy.
Retroverted uterus; Other names: Tipped uterus: A transvaginal ultrasound showing a retroverted uterus during pregnancy. The cervix lies posteriorly to the urinary bladder, and the uterus normally extends superiorly from it, but the direction of the body of the fetus reveals that the uterus extends backwards. Specialty: Gynaecology: Treatment ...
The average life expectancy for women is 80.2 years, per the CDC, which means women spend about a third of their life in this post-menopausal phase. So, while women live longer, on average, than ...
The endocannabinoid system plays a vital role in this synchrony in the uterus, influencing uterine receptivity, and embryo implantation. [5] The embryo expresses cannabinoid receptors early in its development that are responsive to anandamide (AEA) secreted in the uterus. AEA is produced at higher levels before implantation and is then down ...
Around 50% of women of childbearing age in developed countries like the United Kingdom are overweight or obese before pregnancy. [105] Diet modification is the most effective way to reduce weight gain and associated risks in pregnancy.
