Polycopie: Hereditary infertility and sterility.

Course Summary

The course "Hereditary Infertility and Sterility" explores the genetic origins of reproductive failures in animals. It examines how chromosomal abnormalities (such as Robertsonian translocations, aneuploidies like trisomy X) and specific gene mutations contribute to infertility or sterility. Students learn about the physiological impact of these defects on the reproductive tract, gamete quality, embryo development, and hormonal regulation.

Special attention is given to the identification of hereditary syndromes through cytogenetic analysis, molecular testing, and reproductive history evaluation. The course also covers the influence of inbreeding, breed predispositions, and genetic drift on fertility rates.

Practical strategies for diagnosis, management, and prevention are discussed, including selective breeding, genetic counseling, and advanced reproductive technologies (e.g., embryo transfer, IVF). Ethical considerations related to breeding animals with known genetic defects are critically analyzed.

By the end of the course, students will be equipped with the knowledge to recognize hereditary causes of infertility and sterility, assess the reproductive risks in breeding programs, and propose genetic strategies to enhance herd fertility.
