Lecture Notes

Introduction The uterine cycle, also known as the endometrial cycle, involves changes in the uterine lining (endometrium) in preparation for potential pregnancy. The cycle can be divided into three main phases: the menstrual phase, the proliferative phase, and the secretory phase. These phases correspond with the ovarian cycle and are regulated by hormonal changes.

1. Menstrual Phase

  • Duration: Typically lasts from day 1 to day 5 of the menstrual cycle.
  • Hormonal Influence:
    • Decline in Progesterone and Estrogen: The drop in these hormone levels triggers the shedding of the endometrial lining.
  • Uterine Changes:
    • The functional layer of the endometrium is shed, resulting in menstrual bleeding.
    • This phase marks the beginning of a new menstrual cycle.
  • Physical Symptoms:
    • Common symptoms include menstrual cramps (dysmenorrhea), bloating, and fatigue.

2. Proliferative Phase

  • Duration: Typically lasts from day 6 to day 14, ending with ovulation.
  • Hormonal Influence:
    • Estrogen: Produced by the developing ovarian follicles, estrogen stimulates the regeneration and thickening of the endometrial lining.
  • Uterine Changes:
    • The endometrium rebuilds and thickens, preparing for potential implantation of a fertilized egg.
    • Glandular and vascular structures in the endometrium increase.
  • Physical Symptoms:
    • There are generally fewer symptoms in this phase, but some individuals may notice increased cervical mucus, which becomes clearer and more stretchy as ovulation approaches.

3. Secretory Phase

  • Duration: Typically lasts from day 15 to day 28.
  • Hormonal Influence:
    • Progesterone: Secreted by the corpus luteum, progesterone further prepares the endometrium for potential implantation.
    • Estrogen: Continues to support the endometrial changes.
  • Uterine Changes:
    • The endometrium becomes more glandular and vascular, creating a nutrient-rich environment for a potential embryo.
    • If fertilization and implantation do not occur, the corpus luteum degenerates, leading to a decline in progesterone and estrogen levels.
  • Physical Symptoms:
    • Some individuals may experience symptoms such as breast tenderness, bloating, and mood swings due to hormonal changes.

Takeaway Assignments

  1. Cycle Phase Identification:

    • Track your menstrual cycle for two months, identifying and noting the phases of the uterine cycle. Pay attention to any physical symptoms and correlate them with the different phases.
  2. Uterine Health Research:

    • Research one condition related to the uterine cycle (e.g., endometriosis, uterine fibroids). Prepare a short presentation on its causes, symptoms, and treatment options.

Relevant Scenarios and Case Studies

Scenario 1: A 28-year-old woman experiences heavy menstrual bleeding and severe cramps during her menstrual phase. She is concerned about the cause and seeks medical advice.


  • This scenario could indicate conditions such as endometriosis or fibroids. Understanding the uterine cycle phases and hormonal influences can help her track symptoms and seek appropriate medical intervention for diagnosis and treatment.

Case Study 1: A 30-year-old woman wants to optimize her chances of conception and is learning about the changes in her uterine lining during the different phases of her cycle.


  • By understanding the proliferative and secretory phases, she can identify the best times for conception and ensure her uterine lining is optimal for implantation. She can use tracking methods to monitor her cycle and seek medical advice if needed.

Final Topic Summary

The uterine cycle involves three main phases: the menstrual phase, the proliferative phase, and the secretory phase. Each phase is regulated by hormonal changes and involves specific changes in the endometrial lining to prepare for potential pregnancy. Understanding these phases helps in managing menstrual health, optimizing fertility, and identifying potential uterine health issues.
