Unit 2237: Reproductive Physiology in Animals

1. Introduction to Reproductive Physiology

• Overview of reproductive systems in animals
• Key reproductive organs: testes, ovaries, uterus, accessory glands
• Hormones regulating reproduction: overview
• Importance of reproductive physiology for species continuation

2. Male Reproductive Physiology

2.1 Anatomy of the Male Reproductive System

• Testes: structure and function
• Epididymis: sperm maturation and storage
• Vas deferens: sperm transport
• Accessory glands: seminal vesicles, prostate, bulbourethral glands

2.2 Spermatogenesis

• Process and stages of spermatogenesis
• Regulation by hormones (FSH, LH, testosterone)

2.3 Hormonal Regulation

• Role of hypothalamus and pituitary gland
• Feedback mechanisms

3. Female Reproductive Physiology

3.1 Anatomy of the Female Reproductive System

• Ovaries: structure and function
• Fallopian tubes: ovum transport
• Uterus: implantation site and support
• Vagina: copulatory organ

3.2 Oogenesis

• Process and stages of oogenesis
• Follicular development

3.3 Menstrual Cycle

• Phases: follicular, ovulation, luteal, menstruation
• Hormonal changes and regulation (FSH, LH, estrogen, progesterone)

4. Fertilization and Pregnancy

4.1 Fertilization Process

• Sperm-egg interaction
• Formation of zygote

4.2 Implantation

• Embryo implantation in uterus
• Role of uterine environment

4.3 Embryonic and Fetal Development

• Stages of development
• Placenta formation and function

4.4 Hormonal Maintenance of Pregnancy

• Role of progesterone and other hormones

5. Reproductive Hormones

• Gonadotropin-releasing hormone (GnRH): role and secretion
• Follicle-stimulating hormone (FSH): functions in male and female
• Luteinizing hormone (LH): triggers ovulation and testosterone production
• Estrogen: effects on reproductive tissues
• Progesterone: maintenance of pregnancy
• Testosterone: male secondary sexual characteristics and spermatogenesis

6. Reproductive Cycles

6.1 Estrous Cycle

• Phases and hormonal regulation
• Species variations

6.2 Menstrual Cycle

• Comparison with estrous cycle

6.3 Seasonal Breeding Patterns

• Environmental and hormonal influences
• Examples in different species

7. Reproductive Behavior

• Mating rituals and courtship displays
• Mate selection criteria
• Territoriality and competition
• Parental care behaviors
• Hormonal influences on reproductive behavior

8. Reproductive Technologies

• Artificial insemination: techniques and benefits
• In vitro fertilization (IVF): process and applications
• Embryo transfer: methodology and uses
• Cloning: principles and ethical considerations
• Impact on breeding efficiency and genetic diversity
