Abstract
The analysis of the available data allows to conclude that changes of the orbital periods in both Algol-type systems, SW Cyg and U Sge, are correlated with the brightness variations of the late-type loser. The episodes of decrease of the orbital period are accompanied by minimum of brightness of the loser in both cases.
