Uterine hypoplasia, also known as naive uterus or infantile uterus, is a reproductive disorder characterized by hypoplasia of the uterus. It is usually due to pubertal failure/hypogonadism and may be treated with puberty induction using estrogens and/or progestogens. See also

Inflammatory lymphedema
Bilateral lower extremity inflammatory lymphedema (BLEIL) is a distinct type of lymphedema occurring in a setting of acute and prolonged standing, such as in new recruits during basic training. The possible underlying mechanisms are thought to be venous congestion and inflammatory vasculitis. Physiology
Lymph is formed from the fluid that filters out of the blood circulation and contains proteins, cellular debris, bacteria, etc. The collection of this fluid is carried out by the initial lymph collectors that are blind-ended endothelial-lined vessels with fenestrated openings that allow fluids and particles as large as cells to enter. Once inside the lumen of the lymphatic vessels, the fluid is guided along increasingly larger vessels, first with rudimentary valves to prevent backflow, which later develops into complete valves similar to the venous valve. Once the lymph enters the fully valved lymphatic vessels, it is pumped by a rhythmic peristaltic-like action by smooth muscle cells within the lymphatic vessel walls. This peristaltic action is the primary driving force, moving lymph within its vessel walls. The regulation of the frequency and power of contraction is regulated by the sympathetic nervous system. Lymph movement can be influenced by the pressure of nearby muscle contraction, arterial pulse pressure and the vacuum created in the chest cavity during respiration, but these passive forces contribute only a minor percentage of lymph transport. The fluids collected are pumped into continually larger vessels and through lymph nodes, which remove debris and police the fluid for dangerous microbes.
