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.
