Pregnant Woman at 15 Weeks of Gestation, Lateral View (Black Skin)

Description

Seen from the side, the maternal torso is rendered semi-transparent so that the gravid uterus sits low in the true pelvis and lower abdomen, with the fetus at approximately 15 weeks curled in a flexed attitude inside the amniotic sac. The umbilical cord loops anterior to the fetal trunk toward the placental site on the uterine wall, while the fundus has risen just above the pelvic brim. Anterior to the uterus lie the urinary bladder and, inferiorly, the vagina; posteriorly the rectum and sigmoid colon are displaced, with loops of small intestine crowded superiorly. The bony framework of lumbar vertebrae, sacrum and the pelvic bone frames the pelvic contents, and the maternal hands rest on the abdomen and lumbar region. By the fifteenth gestational week the fetus has completed organogenesis and is in a phase of rapid growth, and the enlarging uterus is typically palpable between the symphysis pubis and the umbilicus, making fundal height assessment clinically meaningful. This lateral projection shows why early second-trimester pregnancy brings urinary frequency from bladder compression, constipation from rectosigmoid displacement, and lumbosacral strain as the centre of gravity shifts forward. It is also the anatomy behind second-trimester ultrasound orientation, anatomy screening, and the timing of amniocentesis when indicated. The image suits obstetric and midwifery teaching sequences that track uterine growth week by week, antenatal class handouts, and patient-facing material explaining common second-trimester symptoms. Publishers of pregnancy guides, prenatal apps and women's health websites can use it as a clear stage marker within a continuous series, while clinicians may show it in consultation to relate fetal size and position to maternal pelvic and abdominal organs.
