Lesson 3 • Reproductive Endocrinology Basics

Introduces the hypothalamic-pituitary-gonadal axis and key reproductive hormones. Establishes hormonal vocabulary used throughout the entire course.

Lesson 4 • Female Reproductive Anatomy and Function

Examines ovarian, uterine, and cervical anatomy across species. Links structural variation to differences in ovulation and implantation strategies.

Lesson 1 • Seasonality and Photoperiod Control

Explains melatonin-mediated photoperiodic regulation of reproductive seasonality. Prepares students to manage breeding in seasonally polyestrous species.

Lesson 2 • Phases of the Estrous Cycle

Defines proestrus, oestrus, metestrus, and dioestrus with associated hormonal profiles. Builds on HPG axis knowledge to explain cyclic ovarian activity.

Lesson 3 • Cycle Detection and Monitoring Methods

Covers vaginal cytology, progesterone assays, and ultrasound for cycle staging. Directly applicable to clinical and research reproductive monitoring.

Lesson 4 • The Menstrual Cycle in Primates

Contrasts menstrual cycle phases with estrous cycles, emphasising endometrial shedding. Highlights primate-specific hormonal dynamics relevant to biomedical research.

Lesson 1 • Implantation Mechanisms and Types

Classifies implantation as central, eccentric, or interstitial and describes trophoblast invasion. Prepares students to recognise implantation failure causes.

Lesson 2 • Embryo Transport and Uterine Preparation

Covers oviductal transport mechanisms and uterine receptivity windows. Links embryo timing to endometrial synchrony requirements.

Lesson 3 • Oocyte Activation and Cortical Reaction

Describes calcium oscillations, cortical granule exocytosis, and polyspermy blocks. Establishes the cellular events that initiate embryonic development.

Lesson 4 • Sperm Capacitation and Acrosome Reaction

Details biochemical changes enabling sperm to fertilise an oocyte. Connects capacitation biology to in vitro fertilisation media design.

Lesson 1 • Placental Transport and Exchange Functions

Examines passive diffusion, active transport, and endocytosis for nutrient and gas transfer. Connects barrier thickness to exchange efficiency across placental types.

Lesson 2 • Placental Endocrine Functions

Covers placental production of progesterone, oestrogens, and placental lactogens. Shows how placental hormones maintain pregnancy and prepare for parturition.

Lesson 3 • Fetal Monitoring and Prenatal Assessment

Introduces ultrasound biometry, Doppler flow, and fetal fluid analysis for health assessment. Prepares students to apply diagnostic tools in clinical pregnancy management.

Lesson 4 • Organogenesis and Fetal Growth Milestones

Traces major organ system development and fetal growth curves across gestation. Establishes timing benchmarks used in prenatal diagnostics and management.

Lesson 1 • Hormonal Initiation of Parturition

Explains fetal cortisol surge, prostaglandin release, and oxytocin feedback in labour onset. Builds on placental endocrinology to explain the parturition trigger sequence.

Lesson 2 • Colostrum, Passive Immunity, and Neonatal Nutrition

Examines colostrum composition, immunoglobulin absorption windows, and early nutrition needs. Connects passive immunity transfer to neonatal survival outcomes.

Lesson 3 • Stages of Labour and Delivery

Defines cervical dilation, active expulsion, and placental delivery stages with timing norms. Provides clinical benchmarks for distinguishing normal from dystocia presentations.

Lesson 4 • Postpartum Uterine Involution

Describes uterine size reduction, lochia discharge, and endometrial regeneration after birth. Prepares students to evaluate postpartum reproductive health and rebreeding readiness.

Lesson 1 • Semen Collection and Initial Evaluation

Covers electroejaculation, artificial vagina, and manual collection methods with safety protocols. Establishes baseline semen quality assessment skills for all subsequent processing steps.

Lesson 2 • Semen Cryopreservation Protocols

Details extender formulation, cryoprotectant addition, cooling curves, and thaw protocols. Connects cryobiology principles to practical straw preparation and storage.

Lesson 3 • Embryo Evaluation, Transfer, and Cryopreservation

Covers IETS morphological grading, transfer technique, and vitrification versus slow-cool freezing. Prepares students to make transfer and storage decisions based on embryo quality.

Lesson 4 • Semen Analysis and Quality Parameters

Teaches motility, morphology, concentration, and viability assessment using standard laboratory methods. Provides objective criteria for accepting or rejecting semen for use.

Lesson 1 • Male Reproductive Tract Disorders

Examines orchitis, epididymitis, testicular degeneration, and prostatic disease with clinical signs. Provides diagnostic criteria for evaluating breeding soundness in males.

Lesson 2 • Female Reproductive Tract Disorders

Covers ovarian cysts, pyometra, endometritis, and uterine tumours with diagnostic criteria. Connects hormonal imbalances from earlier chapters to specific pathological outcomes.

Lesson 3 • Infectious Causes of Reproductive Failure

Identifies bacterial, viral, and protozoal pathogens causing abortion, infertility, and neonatal loss. Emphasises zoonotic risk awareness and biosecurity principles.

Lesson 4 • Pregnancy Loss and Abortion Investigation

Outlines systematic approaches to diagnosing abortion storms and sporadic pregnancy loss. Integrates pathology, serology, and history-taking into a diagnostic framework.

Lesson 1 • Herd Reproductive Performance Metrics

Introduces conception rate, calving interval, and days open as key performance indicators. Enables students to audit and improve herd-level reproductive efficiency.

Lesson 2 • Pregnancy Diagnosis Methods

Compares rectal palpation, ultrasound, hormone assays, and clinical signs for pregnancy confirmation. Provides practical decision trees for selecting the most appropriate method.

Lesson 3 • Artificial Insemination Techniques

Details semen thawing, dose preparation, and insemination technique by species. Builds directly on semen processing skills to achieve optimal conception rates.

Lesson 4 • Wildlife and Conservation Reproductive Management

Applies assisted reproduction and genetic management to endangered species programmes. Integrates population genetics with reproductive technology for conservation outcomes.

Lesson 5 • Nutrition and Body Condition in Reproduction

Examines body condition scoring, energy balance, and micronutrient roles in reproductive performance. Connects nutritional status to cycle regularity, conception, and pregnancy maintenance.
