    Study Notes

    Menstruation

    • Menstruation is the episodic uterine bleeding in response to cyclic hormonal changes.
    • It involves a complex interplay of events within the endometrium, hypothalamus, pituitary glands, and ovaries.
    • The purpose of the menstrual cycle is twofold: to bring an ovum to maturity and to renew the uterine tissue bed.

    Factors Affecting Menstrual Cycle Regularity

    • Age
    • Physical and emotional status
    • Environmental influences

    Key Terms

    • Graafian follicle: An ovarian oocyte activated by FSH, developing into an ovum with a surrounding membrane and fluid.
    • Ovulation: The release of a mature egg from the ovary, allowing fertilization. Ovulation is approximately 14 days from the end of the cycle, not necessarily day 14 of the cycle.
    • Corpus luteum: A follicle left behind after ovulation, producing lutein, a yellow fluid rich in progesterone (yellow body).
    • Progesterone: A hormone that is thermogenic (involved in heat regulation).
    • Corpus albicans: A white fibrous tissue replacing the corpus luteum as it regresses.

    Menarche and Puberty

    • Puberty: The transitional stage between childhood and sexual maturity.
    • Menarche: The first menstruation.
    • Initially, menstrual cycles are irregular.
    • Menstrual periods tend to become regular after a year or more.

    Menstrual Cycle Length and Flow

    • Average menstrual cycle length is 28 days.
    • Average menstrual flow duration is 4-6 days.
    • Counting the cycle: Start from the beginning of one flow to the next.

    Characteristics of Normal Menstrual Cycles

    • Menarche: Average age of onset is 12-13 years, with a range of 9-17 years.
    • Interval between cycles: Average 28 days, with 23-35 days being typical.
    • Duration of menstrual flow: Average 5 days, with a range of 3-6 days.
    • Amount of menstrual flow: Average 50 mL (range 20-80 mL).
    • Color of menstrual flow: Dark red, a combination of blood, mucus, and endometrial cells.

    Physiology of the Menstrual Cycle

    • Hypothalamus: Releases GnRH, initiating the menstrual cycle.
    • Pituitary gland: Under the influence of GnRH, produces LH and FSH.
    • Ovaries: FSH stimulates ovarian production of estrogen. LH triggers ovulation and corpus luteum development.
    • Uterus: Prepares the uterine lining for potential implantation.

    Ovulation Timing

    • If your average menstrual cycle is 28 days long, you will ovulate around day 14.
    • If your cycle is 30 days long, you will ovulate around day 16.

    Menstrual Flow Composition

    • Blood from ruptured capillaries
    • Mucin from glands
    • Fragments of endometrial tissue
    • Microscopic pieces, atrophied endometrial tissue, and unfertilized ovum
    • The first day of the flow marks the beginning of a new cycle.

    Blood and Iron Loss

    • Average blood loss is 20-80 mL.
    • Average iron loss is 11 mg.

    Ovarian and Uterine Cycles

    • The ovarian and uterine cycles occur simultaneously.
    • They are divided into phases (follicular, ovulation, luteal, and menstrual).

    Ovarian Cycle

    • Follicular phase: development of follicles
    • Ovulation phase: release of the egg
    • Luteal phase: formation of corpus luteum
    • Menstrual phase: shedding of the uterine lining

    Corpus Luteum

    • If fertilization occurs, the corpus luteum remains for the major portion of pregnancy (16–20 weeks).
    • If fertilization doesn't occur, the corpus luteum regresses and is replaced by corpus albicans.

    Corpus Albicans

    • If conception does not occur, the corpus luteum regresses and is gradually replaced by white fibrous tissue.

    Menstrual Phase

    • If conception does not occur, the unfertilized ovum deteriorates within 4-5 days.
    • The endometrial lining sheds, marking the beginning of a new cycle.

    Endometrial/Uterine Cycle

    • Proliferative phase
    • Secretory phase
    • Ischemic phase
    • Menstrual phase

    Proliferative Phase

    • Also known as estrogenic, follicular, or postmenstrual phase.
    • Characterized by the thickening of the endometrium.
    • Thickening occurs due to estrogen.

    Secretory Phase

    • Progestational, luteal, or premenstrual phase.
    • Extends from the time of ovulation.
    • Marked by the production of progesterone and endometrial thickening.

    Ischemic Phase

    • Happens 7-10 days after ovulation.
    • Due to regression of corpus luteum.
    • Marked by a drop in hormones.
    • Progressive decrease in blood supply to the endometrium resulting in necrosis and impending menstruation
    • The functional endometrial layer separates from the basal layer.

    Menstrual Phase

    • Day 1 of the menstrual cycle, starting with the shedding of the functional endometrial layer.
    • Initiated by periodic vasoconstriction in the upper layers.
    • It marks the start of a new cycle.

    Cervical Changes

    • Cervical mucus alters throughout the cycle.
    • Helpful for fertility.
    • Thin, stretchy, and copious mucus is ideal for sperm.
    • Cervical mucus plays a critical role in fertility
    • During ovulation, the cervical mucus becomes watery, stretchy, and plentiful - this aids sperm survival and penetration.

    Testing for Ovulation

    • Fern test: Cervical mucus forms fern patterns on a glass slide just before ovulation.
    • Spinnbarkeit test: Stretchability of cervical mucus indicates ovulation.

    Health During Menstruation

    • Exercise: Moderate exercise is recommended.
    • Sexual Relations: Not contraindicated but condoms are recommended.
    • Daily Activities (ADL): Daily activities are not limited.
    • Rest: Additional rest may benefit those with dysmenorrhea.
    • Nutrition: There are no dietary restrictions. Iron supplementation may help replace lost iron.

    Menstrual Disorders

    • Dysmenorrhea: Painful menstruation. Can be primary (from uterine contractions) or secondary (from pelvic issues).
    • Premenstrual syndrome (PMS): A complex condition with cyclic symptoms (fluctuations in mood, etc).
    • Premenstrual dysphoric disorder (PMDD): More severe form of PMS, involving intense irritability, depression, or anxiety prior to menstruation.
    • Abnormal uterine bleeding: Any form of bleeding that is irregular in amount, duration, or timing. (Anovulation, Pregnancy, Infections, etc.)
    • Oligomenorrhea/hypomenorrhea: Decreased menstruation.
    • Polymenorrhea: Frequent menstruation.
    • Menorrhagia: Abnormally heavy menstrual bleeding.
    • Metrorrhagia: Bleeding between menstrual periods.

    Menopause

    • Menopause: Cessation of menstrual cycles.
    • Postmenopausal period: Time following menopause.
    • Perimenopausal period: Period during which menopausal changes occur.

    Health Teaching During Menopause

    • Educate women about the changes and their impact on daily life.
    • Address hormone replacement therapy options.
