phagocytic activity of neutrophils and the oral hormonal contraceptives

The phagocytic activity of neutrophils from OCs users was assayed by the method of Leight et al. [1977] using the yeast "Candida albicans". Significant diminution of the phagocytic activity was observed when the assay was performed with the neutrophils in its own serum. However, when the assay was performed with the neutrophils suspended in pooled serum, no significant difference was observed in comparison to the controls. It is concluded that sera from OCs suers may contain factor[s] that depress the phagocytic activity of neutrophils. The possible responsible factor[s] and the significarce of such diminished phagocytic activity were discussed
