Although PUFAs play an important role in the regulation of reproduction, their role in testis development in the rooster is unknown.
Other members of the relaxin family are known to play a role in the regulation of reproduction.
Workers therefore play an important role in the regulation of reproduction, but presumably only after the queens themselves have established rank orders.
A myriad of hormones are directly or indirectly involved in the regulation of reproduction; however, the hormone leptin seems to be the most direct link between fat/metabolism and reproduction [15].
Leptin is involved not only in the control of food intake, energy expenditure and metabolism, but also in the regulation of reproduction [2], [3].
Further studies are required to define the physiological importance of relaxin-3 in the regulation of reproduction.
The function of leptin, initially confined to its role in energy homeostasis and obesity, has now expanded to the regulation of reproduction, glucose homeostasis, bone formation, wound healing and the immune system.
These results suggest that the role of lepr in thoracic and cranial ganglia may be associated primarily with the regulation of reproduction.
The characterization of membrane receptors related to the regulation of reproduction within this model nematode organism is very important for both the study of evolutionary biology as well as the study of the molecular endocrinology of reproduction in multicellular organisms.
Furthermore, the hypothesis of manipulative regulation of reproduction appears to gain renewed support from the observation that, at least in honeybees, the regulation of reproduction is based on a very large number of substances from multiple glands [ 13, 14].
As a hormone it has important functions in the regulation of body weight, reproduction, immune functions, bone formation and growth [ 1].
