The object of the present study was to investigate the effect of bilateral oophorectomy
(OOX) on CD4+ and CD8+ subsets of T-lymphocytes in 8 immunologically healthy perimenopausal
women with regular bleeding. Between the 12th and 16th week after OOX, CD8+ (%) increased
in all of the investigated women (mean values compared to values before OOX: 37.8
± 3.4 vs 26 ± 4.13, p < 0.05). CD4+ increased in five women, and decreased in another
three (means: 36.4 ± 3.6 vs 38 ± 4.6). The immunoregulatory index (CD4+/CD8+ ratio)
declined in seven women, while it was unchanged in one (means: 1.09 ± 0.2 vs 1.71
± 0.22, p < 0.05). The compliance of the treatment was controlled by serum estrogen,
LH and FSH. From these results it is apparent that surgically induced hypoestrinism
inhibits immunoregulation in perimenopausal women.
