BACKGROUND Endometriosis (EM) is highly associated with infertility. The precise mechanism underlying EM-associated infertility remains controversial. This study aimed to investigate the pathogenesis of infertility in women with EM by comparing FoxP3+ T regulatory cells (Tregs) expression in the eutopic endometrium of infertile women with EM and endometrium from healthy fertile women. METHODS...

Extensive efforts have been devoted to developing new EM tools and modelling techniques. Considerably less attention has been paid to the aspects of acquiring and introducing EM tools in organisations. Our grounded theory ...
