The pineal glands of pregnant nursing sows were studied by light electron microscopy. Similar structural changes in the pineal glduring pregnancy lactation were noted as follows, 1) a proliferation of glial cells concurrent with a decrease in the number of pinealocytes, 2) a relative increase in the number of pinealocytes with cytoplasmic accumulation of dense bodies, 3) an increase in number of presumptive microglia. It appears that pregnancy lactation exert a complex influence on pineal function, with a predominantly stimulating effect.
