Hypothalamus and Thymus

Overview of Hormones

  • Estrogen:

    • Important for normal menstruation and conception.

    • Locks in first menses and maintains pregnancy.

  • Progesterone:

    • Key role in maintaining pregnancy. Low levels can lead to difficulties conceiving and miscarriages.

Menstrual Cycle Issues

  • Menorrhea:

    • Medical term for menstruation.

    • Variability in menstrual cycle:

      • Cycle duration can range from 24-38 days.

      • Duration of menstruation varies (e.g., 2-10 days).

  • Low estrogen or progesterone levels can lead to issues with menstruation and conception.

Hormonal Treatments

  • Hormonal medications may be necessary for low estrogen or low progesterone levels, often prescribed alongside birth control to regulate hormone levels.

  • PCOS (Polycystic Ovary Syndrome):

    • Affects conception; often treated with medications like metformin.

Age and Follicle Loss

  • As age increases, particularly post-50, females lose follicles that produce estrogen and progesterone, leading to:

    • Symptoms of menopause (e.g., irritability, hot flashes).

Hormonal Regulation in Males

  • FSH (Follicle Stimulating Hormone):

    • Produces estrogen.

  • LH (Luteinizing Hormone):

    • Produces testosterone.

Insulin and Glucose Regulation

  • Insulin:

    • Produced by pancreas, helps store glucose in liver, muscles, and adipose tissues.

  • Glucagon:

    • Breaks down stored glucose to maintain blood sugar levels.

Tumors and Hormonal Imbalance

  • Excess hormones often linked to tumors, while decreased production may indicate autoimmune disorders.

Prolactin and Prolactinoma

  • Prolactin:

    • Functions in the ovaries and breast, promoting milk production.

  • Excessive prolactin (prolactinoma) can occur due to tumors, leading to:

    • Inappropriate milk production in non-pregnant females.

    • Symptoms include greenish-discharged fluid from the breast and potential fertility issues.

  • Monitoring for catactorrhea (fluid secretion) and unilateral discharge is important to rule out breast cancer.
