| dc.description | The implementation of innovative procedures in zootechnics, specifically in the field of animal reproduction, demand for a deep understanding of the physiological mechanisms operating in the animal organism. Reproductive success is dependent upon several factors, among them, the existence in the female of adequate conditions so that the male gametes ascend through the reproductive tract and reach the oocyte. The purpose of this doctoral thesis is to study sorne of the characteristics of bovine cervical mucus, under normal conditions, the first medium spermatozoa have to go through towards the site of fertilization. In order to achievethe aforementioned purpose, this dissertation is organized in chapters, many of them an independent manuscript submitted to a peer-reviewed journal. The first chapter focuses on 'the state of the art' as regards bovine cervical mucus. This section also states the experimental hypothesis and the general objectives of this thesis. Chapters two and three describe the crystallizations present in bovine cervical mucus at oestrus. The fourth chapter deals specifically with the ultrastructural characteristics of cervical secretion in the heifer at oestrus stage.The fifth chapter shows that sorne types of crystalline patterns found for cervical secretion at oestrus are characterized by having a fractal-like geometry. Chapter six discusses, in general terms, the experimental findings of the previous sections, together with the conclusions of the present dissertation. Finally, other associatedmanuscripts are presented in chapter seven, as annexes. | |
