 | Association for Applied Animal Andrology |
About Our Association
The Association for Applied Animal Andrology (4A) is an international organisation that seeks to further the understanding of male reproduction in those animals which are of interest to mankind. It brings together representatives of science, industry and education to focus on a wide spectrum of endeavour, from maximising genetic progress in livestock to preserving rare and endangered species. It also fulfills a unique role by facilitating direct dialogue between cutting-edge science, education, and the animal breeding industries within an international context.
- Male animal anatomy, physiology and endocrinology
- Applied andrological cellular and molecular biology
- Andrological assessment, including semen.
- Male animal reproductive behaviour and reproductive management
- Semen assessment, preservation and insemination
- Semen transport, including methods and regulations
- Good laboratory practices (GLPs) in Animal Andrology
- Applicable biosecurity, including regulatory aspects
- Male reproductive genetics
- Male-factor infertility; causes, diagnosis and consequences
If any of these topics tweak your interest or curiosity, whether as a scientist, animal breeder, livestock producer or pursuant of knowledge, we encourage you to join our association and be part of an exciting and growing area of scientific endeavor as well as its applications in important fields such as world protein production and wildlife preservation.

| President/Treasurer - Professor John Kastelic Professor Kastelic’s origins were on a cattle farm near Edmonton, Alberta, Canada. He received his DVM from the U. of Saskatchewan (US) in 1982, and spent more than 2 years in private practice and 1 year in a MS program at US before transferring to the U. of Wisconsin-Madison. Under the supervision of OJ Ginther, he was involved in early studies on the use of ultrasonography for reproductive imaging and studying the ovaries, uterus and conceptus in cattle. He completed his PhD in 1990 and was then recruited by Glenn Coulter (AAAA Founding President) to work at the Lethbridge Research Centre (~200 km/130 miles from Calgary). In 2012, he joined the U. of Calgary, Faculty of Veterinary Medicine where he is Professor of Theriogenology and Head of the Department of Production Animal Health. Contact Details: |
| Vice President - Assistant Professor Guilherme Rizzoto Dr. Rizzoto graduated as a veterinarian in 2015 from the Federal University of Pelotas, Brazil, and received his PhD (“Pathogenesis of Heat Induced Infertility in Male Mammals”) in 2020 from the University of Calgary (Calgary, AB, Canada) where he worked with Dr. John Kastelic. From 2021- 22, he held a post-doctoral position (Promising Young Researcher Award) at UNESP (São Paulo State University – Botucatu, SP, Brazil) and is currently a post-doctoral researcher at Ghent University, with the support of a BOF Award (2022 – 25). He is also a Professor at UNESP in the Graduate Program in Animal Biotechnology (2019 - Ongoing). He is an enthusiast of animal andrology and theriogenology with several publications in the area and has also received important awards, including the Gustav Rosenberger Memorial Fund for young researchers. His research is focused upon impacts of heat stress on male fertility and he has received significant international grants in support. Contact Details: ResearchGate: Guilherme Rizzoto |
| Director - Doctor Laura Abril-Parreño Dr. Abril-Parreño is a postdoctoral researcher in the Department of Physiology at the Faculty of Veterinary Medicine, University of Murcia (Spain). Her main interests are in sperm biology and the molecular mechanisms regulating the interaction of sperm with the female reproductive tract. In 2021, she earned her PhD from the University of Limerick (Ireland), where her research focused on sperm transport across the cervix in ewe breeds known to exhibit varying pregnancy rates following cervical artificial insemination with frozen-thawed semen. Through this work, she developed expertise in a range of Omics technologies—including transcriptomics, glycomics, and metabolomics—as well as in ultra-performance liquid chromatography (UPLC) and mass spectrometry (MS), with applications in reproductive biology. Recently, Dr. Abril-Parreño was awarded the prestigious Juan de la Cierva Postdoctoral Fellowship in Spain. In addition, she is a member of the Spanish Association for the Study of Reproductive Biology (ASEBIR) and serves on the organizing committees of the COST Action ANDRONET (European Andrology Network – research coordination, education, and public awareness) and the Association for Applied Animal Andrology.

| Director - Associate Professor Elisa Giaretta Dr Elisa Giaretta obtained her veterinary degree from the University of Bologna in 2011, followed by her PhD (title “ Effect of antioxidant supplementation on pig and horse gamete storage”) under the supervision of Professor Carlo Tamanini. She is currently associate professor at the University of Padua in the Department of Comparative Biomedicine and Food Science. Her research activity encompasses conservation of gametes and their quality parameters, including effects of natural antioxidants. In addition, she studies the energy metabolism and changes associated with capacitation and the acrosome reaction in sperm of different domestic species. Concurrent research interests are in farm animal adaptation and stress responses to change, aimed at developing animal health and welfare biomarkers. She has received several grants and awards and teaches subjects in both Animal and Veterinary Sciences. Contact Details: |
| Director - Professor Christine Aurich Associate Professor Aurich graduated in Veterinary Medicine from the Hannover Veterinary School, Germany in 1990. Her subsequent studies and positions have been focused upon animal reproduction, including her PhD thesis, “Endocrine regulation of reproduction in the horse” from the Hannover Veterinary School, Germany, in 1997. Since 1998, she has been at the University of Veterinary Sciences (Vetmeduni), Vienna, Austria where she has held positions, including Head of the Graf Lehndorff-Institue for Equine Science, Head of the Clinic for Horses, and Head of the PhD Curricular Committee.
