Unit 1585: Reproductive Endocrinology and Hormonal Regulation

1. Overview of Reproductive Endocrinology

• Definition and scope of reproductive endocrinology
• Hormones involved in reproductive system regulation
• Differences and similarities in male and female reproductive hormone systems

2. Hormonal Regulation of the Menstrual Cycle

• Phases of the menstrual cycle: follicular, ovulation, luteal, and menstruation
• Role of key hormones:
  • Estrogen: production, function, and effects
  • Progesterone: role in luteal phase and endometrial preparation
  • Follicle-Stimulating Hormone (FSH): stimulation of follicle growth
  • Luteinizing Hormone (LH): triggering ovulation and corpus luteum formation
• Feedback mechanisms governing hormonal secretion

3. Male Reproductive Hormones

• Testosterone: synthesis in Leydig cells, functions in development and maintenance
• Follicle-Stimulating Hormone (FSH): role in spermatogenesis
• Luteinizing Hormone (LH): stimulation of testosterone production
• Hormonal regulation of sperm production and male fertility

4. Female Reproductive Hormones

• Estrogen and its role in follicle development, endometrial growth, and secondary sexual characteristics
• Progesterone's influence on the endometrium and pregnancy maintenance
• FSH and LH roles in follicular development and ovulation
• Interaction of these hormones throughout the menstrual cycle

5. Endocrine Disorders Affecting Reproduction

• Polycystic Ovary Syndrome (PCOS): pathophysiology, symptoms, and hormonal imbalances
• Hypogonadism: causes, effects on reproductive hormone levels and fertility
• Hyperprolactinemia: impact on gonadotropin secretion and reproductive function
• Diagnostic approaches and treatment options

6. Assisted Reproductive Technologies (ART)

• Overview of ART and its significance
• In Vitro Fertilization (IVF): process steps, hormonal stimulation protocols
• Intrauterine Insemination (IUI): indications and procedure
• Hormonal therapies used to support ART and treat infertility
• Ethical considerations and success factors

7. Puberty and Pubertal Development

• Hormonal changes initiating puberty: GnRH, FSH, LH surge
• Development of secondary sexual characteristics in males and females
• Timeline and physiological markers of pubertal progression
• Psychological and social implications

8. Menopause and Hormonal Changes

• Definition and stages of menopause
• Decline in estrogen and progesterone levels
• Physiological and symptomatic manifestations
• Health implications and management strategies
