luteal phase defect

defect /de·fect/ (de´fekt) an imperfection, failure, or absence.defec´tive

---

acquired defect  a non-genetic imperfection arising secondarily, after birth.

aortic septal defect  a congenital anomaly in which there is abnormal communication between the ascending aorta and pulmonary artery just above the semilunar valves.

atrial septal defects , atrioseptal defects congenital anomalies in which there is persistent patency of the atrial septum, owing to failure of the ostium primum or ostium secundum.

Atrial septal defects; cutaway composite view showing possible locations of ostium primum and secundum defects in the right atrium.

birth defect  one present at birth, whether a morphological defect (dysmorphism) or an inborn error of metabolism.

congenital defect  birth d.

congenital ectodermal defect  anhidrotic ectodermal dysplasia.

cortical defect  a benign, symptomless, circumscribed rarefaction of cortical bone, detected radiographically.

endocardial cushion defects  a spectrum of septal defects resulting from imperfect fusion of the endocardial cushions, and ranging from persistent ostium primum to persistent common atrioventricular canal; see atrial septal d. and atrioventricularis communis.

fibrous cortical defect  a small, asymptomatic, osteolytic, fibrous lesion occurring within the bone cortex, particularly in the metaphyseal region of long bones in childhood.

filling defect  any localized defect in the contour of the stomach, duodenum, or intestine, as seen in the radiograph after a barium enema.

genetic defect  see under disease.

luteal phase defect  inadequate secretory transformation of the endometrium during the luteal phase of the menstrual cycle; it can cause habitual abortion.

metaphyseal fibrous defect 

1. fibrous cortical d.

2. nonossifying fibroma.

neural tube defect  a developmental anomaly of failure of closure of the neural tube, resulting in conditions such as anencephaly or spina bifida.

retention defect  a defect in the power of recalling or remembering names, numbers, or events.

septal defect  a defect in a cardiac septum resulting in an abnormal communication between the opposite chambers of the heart.

ventricular septal defect  a congenital cardiac anomaly in which there is persistent patency of the ventricular septum in either the muscular or fibrous portions, most often due to failure of the bulbar septum to completely close the interventricular foramen.

Abnormal communication between the ventricles in ventricular septal defect.

Gynecology A deficiency–seen in 3 to 5% of infertile women and cause of ± 1/3 of recurent early spontaneous abortions–in the amount of progesterone produced—or the length of time produced, which translates into an inability of the endometrium to support pregnancy. See Corpus luteum.
