Infos

Any events that challenge the survival of living organisms may be
classified as stressors. These stressors could include, for
example, lack of food, increased population pressure, predatory
pressure, climatic events or in the case of humans, loss of a loved
one, lack of financial security or uncertainty in the future.
Although most physiological systems are affected by stress, those
systems that regulate reproductive physiology and behaviour are the
most sensitive. All multicellular organisms show a stress related
effect on reproduction, although the more complex organisms, such
as mammals, have the most complex effects.

The objective of this book is to provide a comparative analysis
of the mechanisms by which stress regulates reproduction exploring
the evolution of stress perceiving systems from the simplest
organisms to humans. Taking an integrated approach, utilising a
genes-to-environment overview, the book examines the stressors that
occur at all levels of organisation. These theories are used to
examine and explain human and animal reproductive behaviour and
physiology under stressful conditions providing a well-written,
concise introduction to this important subject.
