Until recently a complex overview of the biology of reproduction in birds was lacking in the scientific literature. This book was originally published in Hungarian in 2014. Now, the revised text of the Hungarian edition is published in English in a two-volume book.
The first volume presents the structure, function and molecular regulation of the reproductive process. It deals with the molecular biology of sex determination and sexual differentiation, with the functional anatomy of the avian ovary, development of ova and the function of the oviduct and the development of the egg, and the molecular and hormonal relationship of calcium metabolism of female birds. It highlights the male gonad, gonoductus and the production of sperm cell, in addition to the presentation of the physiology and the molecular events of fertilization. Finally, the relatively large body of data traverses the questions of regulation of gonadal functions at the level of the neuroendocrine hypothalamo-adenohypophyseal system, and also at the level of the gonadal endocrine functions.
The second volume studies the reproductive process as a part of the annual life cycle of birds, dealing with the relationships between gonadal function and the different elements of the biological cycle.
