EFFECT OF TESTOSTERONE ADMINISTRATION, PRENATALLY AND POSTNATALLY, ON THE IMMUNE-SYSTEM OF RATS
This study was undertaken to investigate and compare in vitro and in
vivo immune parameters between female and male rats. We analysed the
T-cell proliferative responses to syngeneic and allogeneic cellular
antigens (syngeneic and allogeneic mixed lymphocyte reaction), as well
as the IgG levels in the sera of our study groups. It has also been
studied the influence of gonadectomy and the effect of testosterone
administration pre- and postnatally on the above parameters. Our
findings showed that hormonal manipulations, can alter the differences
observed in immune response between female and male rats. In addition,
it is demonstrated that pre- and postnatal sexual steroid manipulations
could provoke long lasting immunological effects
