Nine patients randomly selected from these 22 patients with unexplained infertility were then treated with oral danazol administration for 12 weeks and reexamined at the first mid-secretory phase after the danazol treatment.\nResult(s) : The levels of endometrial α v β3 expression were lower in 22 patients with unexplained infertility than in the fertile control and 35 patients with explained infertility. The 9 patients treated with danazol showed a significant increase in the α v β3 staining.\nConclusion(s) : The significantly decreased expression of endometrial integrin α v β3 suggested that functional, but not morphological, endometrial defect may be one of the causes for the patients with unexplained infertility. Danazol may have a therapeutic potential in improving endometrial function together with up-regulation of α v β3.\nSimilar content being viewed by others\nREFERENCES\nCenters for Disease Control and Prevention (CDC): 1999 assisted reproductive technology success rates, National Summary and Fertility Clinic Reports, 2001.
