Lecture Notes

Introduction The ovarian cycle is a crucial part of the menstrual cycle, involving the maturation of ovarian follicles, the release of an egg, and the preparation of the ovary for potential pregnancy. The ovarian cycle can be divided into three main phases: the follicular phase, ovulation, and the luteal phase.

1. Follicular Phase

  • Duration: Begins on the first day of menstruation and lasts until ovulation (approximately day 1 to day 14 of a typical 28-day cycle).
  • Hormonal Influence:
    • Follicle-Stimulating Hormone (FSH): FSH is secreted by the anterior pituitary gland and stimulates the growth and maturation of ovarian follicles.
    • Estrogen: As follicles develop, they produce increasing amounts of estrogen. This hormone helps rebuild the uterine lining (endometrium) after menstruation.
  • Ovarian Changes:
    • Multiple follicles in the ovaries start to grow, but typically only one becomes the dominant follicle.
    • The dominant follicle continues to mature, while the others regress.
  • Uterine Changes:
    • The rising estrogen levels lead to the thickening of the endometrial lining, preparing it for potential implantation of a fertilized egg.

2. Ovulation

  • Timing: Typically occurs around day 14 of a 28-day cycle.
  • Hormonal Trigger:
    • Luteinizing Hormone (LH) Surge: A significant rise in LH levels, triggered by high estrogen levels, causes the mature follicle to release an egg (oocyte).
  • Ovarian Changes:
    • The mature follicle ruptures, releasing the egg into the fallopian tube.
  • Uterine Changes:
    • The uterine lining continues to thicken and becomes more glandular, creating a supportive environment for potential implantation.

3. Luteal Phase

  • Duration: Begins after ovulation and lasts until the start of menstruation (approximately day 15 to day 28).
  • Hormonal Influence:
    • Progesterone: After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes progesterone. This hormone maintains the thickened endometrial lining.
    • Estrogen: Continues to be produced by the corpus luteum, but at lower levels than progesterone.
  • Ovarian Changes:
    • The corpus luteum is formed from the remnants of the ruptured follicle.
    • If pregnancy does not occur, the corpus luteum degenerates, leading to a decrease in progesterone and estrogen levels.
  • Uterine Changes:
    • Progesterone stabilizes the endometrial lining, making it suitable for implantation.
    • If the egg is not fertilized, the decline in progesterone and estrogen levels causes the endometrial lining to shed, resulting in menstruation.

Quizzes with Answers

Takeaway Assignments

  1. Ovarian Cycle Chart:

    • Create a detailed chart of the ovarian cycle, including the follicular phase, ovulation, and luteal phase. Label the key hormonal changes and their effects on the ovaries and uterus.
  2. Personal Cycle Tracking:

    • Track your own menstrual cycle for two months, focusing on identifying the phases of the ovarian cycle. Note any physical or emotional changes and correlate them with the different phases.

Relevant Scenarios and Case Studies

Scenario 1: A 29-year-old woman experiences irregular menstrual cycles and suspects it might be due to an imbalance in her ovarian cycle.


  • Understanding the ovarian cycle phases can help her track and identify which phase might be disrupted. She should consider keeping a detailed record of her cycles and consulting a healthcare provider for potential hormonal tests and treatment options.

Case Study 1: A 32-year-old woman is trying to conceive and wants to optimize her chances by understanding when she is most fertile.


  • By understanding the timing of ovulation and the role of the LH surge, she can use ovulation predictor kits and track her cycle to identify her fertile window. This knowledge increases the likelihood of successful conception.

Final Topic Summary

The ovarian cycle consists of three main phases: the follicular phase, ovulation, and the luteal phase. Each phase is regulated by specific hormones (FSH, estrogen, LH, and progesterone) and involves distinct changes in the ovaries and uterus. Understanding these phases helps in managing menstrual health, planning for pregnancy, and identifying potential reproductive health issues.
