Today, social progress together with economic development and technological advancement have not only proved too „protective” laws to be wrong, but have seen women enter the workforce in massive numbers around the world. Yet debate still rages in many countries over the benefits or liabilities of special protective labour legislation for women. Evidence of the impact of night work on female reproductive health as presented in the current literature is inconclusive. Moreover, available evidence needs to be interpreted with caution, given the various limitations and inconsistencies among the studies in the measurement of night-work exposure and shift-work patterns. Studies that focus specifically on night work are needed to facilitate an understanding of the impact of circadian disruption on the reproductive health of women undertaking night work.
