Dg. Harkin et al., CHEMOTAXIS OF POLYMORPHONUCLEAR LEUKOCYTES TOWARDS HUMAN PREOVULATORYFOLLICULAR-FLUID AND SERUM USING A SPARSE-PORE POLYCARBONATE FILTRATION MEMBRANE, Journal of reproductive immunology, 27(2), 1994, pp. 151-155
The chemotactic responses of polymorphonuclear leukocytes (PMN) toward
s pre-ovulatory follicular fluid and serum from patients participating
in an in vitro fertilization program were tested in a modified Boyden
chamber using a 'sparse-pore' polycarbonate filtration membrane metho
d. The chemotactic activities of follicular fluids were generally low,
but were significantly higher in conceptual cycles than in non-concep
tual cycles. The chemotactic activities of sera were generally high, b
ut were significantly lower in conceptual cycles. The chemotactic acti
vity of few follicular fluids ever exceeded that of serum, regardless
of the occurrence of conception. These findings demonstrate for the fi
rst time using an appropriate technique, that pre-ovulatory follicular
fluids can be chemotactic for PMN, but the relationship between this
activity, serum chemotactic activity and successful pregnancy is not c
lear.
