The study hypothesizes that women who have a history of intrauterine device expulsion are likely to have "unfavorable uterine conditions," which may include poor positioning, small size, and subtle malformation.
The force of the contractions can be measured with an intrauterine pressure catheter (IUPC), which is a catheter that can be placed through the cervix into the uterus to measure uterine pressure during labor.
The term intrauterine growth retardation (also known as intrauterine growth restriction)(IUGR) is generically defined as a fetus who is at or below the tenth percentile in weight for its gestational age.
With greater access to assisted reproductive techniques like in vitro fertilization and intrauterine insemination, cancer patients who are infertile have a greater chance of conceiving a child.
Outcomes include an increased risk of long-term neurologic and behavioral handicaps, possible intrauterine demise, low blood sugar (hypoglycemia), and low body temperature (hypothermia).
