Book excerpt: Master's Thesis from the year 2015 in the subject Biology - Zoology, , language: English, abstract: In the present study semen samples from NRF bulls were analysed for sperm viability, acrosome integrity and ATP content. The effect of incubation at 37 °C on sperm viability, acrosome integrity and ATP content was investigated on fresh and frozen semen samples from 20 NRF. Semen was incubated at 37 °C and the sperm quality parameters were analysed at 0 hr and after 6 and 24 hrs of incubation for both fresh and frozen samples. Sperm viability and acrosome integrity was assessed with flow cytometry and ATP content with luminometer. The incubation time at 37 °C had a significant effect on all studied parameters. However, ATP content was significantly more affected than sperm viability and acrosome integrity. After 24 hrs of incubation ATP content of frozen samples decreased approximately to 0 for all tested samples, while percentage of viability and acrosome integrity decreased by 78 ± 11.9 %. Percentage of AIL sperm cells of frozen samples decreased at corresponding rate as in fresh samples. Concerning ATP content there was however, a more marked decline in frozen samples compared to fresh samples during incubation. Sperm samples from eight NRF bulls with high and low fertility were also analysed for sperm viability, acrosome integrity and ATP content at 0 hr (right after thawing), 3, 6 and 24 hrs incubation at 37 °C. The ATP content adjusted for % AIL at 0 hr was significantly correlated with fertility measured as 56 days NRR, while % AIL or ATP content analysed separately were not correlated to field fertility.

This book was released on 2022-05-31 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the role of oxidative stress in human reproduction with a focus on men’s health. The physiological roles of reactive oxygen species (ROS) in male fertility are the focus in this book. This topic is important because oxidative stress is a result of the imbalance between ROS and antioxidants in the body which may lead to sperm damage (DNA or count), deformity, and eventually, male infertility. Therefore, for a better understanding of the molecular mechanisms related to male genotoxicity and its regulation in infertility, this book provides an up-to-date view on the impact of oxidative stress factors in male reproduction . The main aim of this book is to collect a series of research articles and reviews from a diverse group of scientists to share their research work on the role of ROS or oxidative stress in physiological and pathological states in relation to (in)fertility in the male. This book presents various state-of-the-art chapters of the recent progress in the field of cellular toxicology and clinical manifestations of various issues related to men’s health and fertility. Topics include cell signaling, DNA damage and infertility, the pathophysiology of disease instigation and distribution, immune toxicity and prevention.

Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

Available in PDF, EPUB and Kindle. Book excerpt: This contemporary account of male fertility provides a much-needed bridge between those seeking to understand the subject from an evolutionary and biological perspective, and those with clinical responsibility for the investigation and treatment of male infertility. Accordingly, the first half of the book deals with evolutionary aspects of male reproduction and sperm competition, sperm production and delivery in man and other animals, spermatogenesis and epididymal function, sperm transport in the female tract, and the apparent decline in human sperm count. The second part of the book puts greater emphasis on clinical problems and opens with a discussion of ICSI, including its value and limitations. This is followed by a review of modern developments in the genetics of male infertility and proceeds to a further chapter on the role of surgical procedures in the treatment of male infertility. The contributors provide a critical review of semen analysis and a full description of the molecular techniques now being used in preimplantation diagnosis and in the study of mitochondrial inheritance. This volume, written by an international team of authors, illustrates the breadth of vision needed to tackle the problem of male infertility.

Available in PDF, EPUB and Kindle. Book excerpt: Theriogenology, the field that studies animal reproductive health and disease, is a challenging field that shows a steady growth. It covers diverse aspects of reproduction in domestic and wild animals, including the assisted reproductive techniques, which have enormously enhanced the ability to rescue endangered species and provide a strong support to the high reproductive efficiency requested by livestock production. Reproductive success, as well as infertility, is the culmination of complex physiological and adaptive processes that guarantee, at the end, a species' ability to reproduce and its survival in a challenging and ever-changing environment. In this book, we present to you a collection of manuscripts exploring various aspects of the reproductive function of mammal and marine species. I hope you find this a useful book in your collection.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the reproductive physiology and endocrinology of fishes is essential for captive maturation and seed production in the field of aquaculture. Studying the spermatology of fishes is a comparatively new focus in aquaculture, which has emerged as an important area of fish research over the past two decades. In this regard, the cryopreservation of fish gametes is a crucial aspect. Moreover, energetics studies of gametes have become essential, considering the loss of vigour in the spermatozoa after cryopreservation.The latest development in this context is the cryopreservation of spermatogonial stem cell, which is also covered in the book, along with detailed information on embryo cryopreservation in fishes and crustaceans. The role of cryopreservation in conservation programmes is another important aspect, one that will especially interest biologists.This book addresses central issues in fish gamete cryopreservation and breeding, while also reviewing the history of cryopreservation. Its most unique feature is the breadth of its coverage, from basic information on reproduction in fishes, to such advanced topics as embryo cryopreservation. Chiefly intended as a handy troubleshooting guide, the book represents a valuable resource for research students in related fields.

Available in PDF, EPUB and Kindle. Book excerpt: Bovine Medicine provides practical and comprehensive information oncattle disease and production and is a key reference for all largeanimal vets. Since the first edition was published in 1991 therehave been significant improvements in disease control andmanagement of cattle. Almost all parts of the book have beenupdated and completely rewritten. There are new chapters onsurgery, embryo transfer, artificial insemination, ethno-veterinarymedicine and biosecurity, and a new consolidating chapter on theinteraction between the animal, environment, management anddisease. The previous edition has sold all over the world, and as aresult of this a greater emphasis has been placed on conditions andtheir treatment in areas other than temperate regions. A newsection entitled "Global Variation in Cattle Practice" has beenincluded with contributors discussing bovine medicine practice intheir part of the world. All in all this is an outstanding resource for any practisingvet and an excellent reference for veterinary students.
