In adenomyosis, the two major frequent symptoms are hypermenorrhea and dysmenorrhea. The incidence of the former is said to be high, ranging from 36 to 70%. It has been found that vascular distribution of the endometrium in adenomyosis is d…

BACKGROUND: One immune characteristic of endometriosis is a decrease in natural killer (NK) cell activity. This study was performed to determine whether an abnormal immune reaction in an endometriosis animal model could be transferred to an…
