Reproductive Physiology – BCSE Study Guide
Overview and Clinical Importance
Reproductive physiology forms the foundation of breeding management, fertility assessment, and reproductive medicine across all veterinary species. Understanding the hormonal regulation of estrous cycles, gametogenesis, pregnancy, parturition, and lactation is essential for diagnosing reproductive disorders, timing artificial insemination, managing dystocia, and supporting neonatal health. This topic integrates knowledge from endocrinology, anatomy, and clinical medicine.
1. Estrous Cycle Physiology
Definition and Terminology
The estrous cycle is the recurring pattern of reproductive hormonal changes in non-primate female mammals that results in periodic sexual receptivity (estrus or "heat"). Unlike the menstrual cycle in primates where the endometrium is shed, estrous animals reabsorb the endometrium if conception does not occur.
