Q

Endocrine feedback loop of testosterone (3)

A
  • Testosterone made in testes, regulated by anterior pituitary luteinizing hormone (LH) and follicle-stimulating hormone (FSH)
  • LH and FSH regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus
  • ↑testosterone in circulation inhibits production of these hormones (negative feedback) – levels are fairly constant at all times, until aging process ↓production

Q

Medical Reasons Androgens may be prescribed by Doc (5)

A
  1. Can be administered medically for protein loss, muscle catabolism, effects of HIV, rarely the treatment of choice by physicians – and mixed success
  2. Delayed puberty – androgens may be used on short-term basis to “kick start” puberty, as long as no underlying pathology exists
  3. Limited use in hormone-sensitive tumors
  4. Anemia – testosterone is potent stimulator of EPO, but other more direct drugs are preferable
  5. Hereditary angioedema (defect in clotting factors) – androgens may be used prophylactically due to their action on liver to restore clotting factors

Q

Points about androgen abuse and athletics- use, prevelance, ect.. (6)

A
  1. Anabolic steroids used to enhance athletic performance,↑ muscle size and strength
  2. Increasingly seen in younger athletes – at least 6% of high school athletes admit to use
  3. Usually obtained illegally, taken in “stacking” dosage to ↑ effects
  4. Use a steroid dosing cycle – athletes have a variety of ways to avoid detection during sports drug testing
  5. No question athletic performance is improved, as is lean body mass and muscle strength - but how much is undetermined
  6. Athletes also use other performance-enhancing techniques such as blood doping, growth hormones

Q

The female cycle and hormone activity (4)

A
  • FSH released by anterior pituitary in follicular phase, which matures into ovum
  • LH released by anterior pituitary at menstrual midpoint, with smaller burst of FSH, for ovulation – follicle releases ovum, then becomes infiltrated with lipids (corpus luteum)
  • Corpus luteum controls second half of menstrual cycle – continues to grow for ~1 week post ovulation, secreting estrogen and progesterone – thickens uterine lining, and progesterone stimulates mucus for potential implantation of a fertilized egg
  • If no fertilization, corpus luteum regresses and menstruation occurs

Q

If the egg is fertilized in the uterus, then……..(4)

A
  • human chorionic gonadotropin (HCG) is released, takes over the role of LH and prevents destruction of corpus luteum
  • Corpus luteum persists until 9-14th week of gestation, producing progesterone to facilitate uterine environment
  • Placenta produces estrogen and progesterone thereafter – also facilitates development of mammary glands for lactation
  • Estrogen may play a role in parturition (labor)

32
Q

Points about adverse effects with oral contraceptives (not a list per se, more concept) - 3

33
Q

Which organ systems are affected by pregnancy?

A

All of them

34
Q

Something to consider about any patients we have who are on oral contraceptives

A

They are effective when taken correctly. If taking at varied times or if there are inconsistancies with taking teh med, then there is a chance the patient can be pregnant.

35
Q

When do many of the changes for a pregnant woman begin and name a couple of general changes that occur

A
  • Most changes begin early
    • Even before pregnancy recognized
  • Most are hormonally driven

A
  • RBC (25-40%) and blood volume (50-100%) increase (around 20th week)
  • Can be anemia early on as body begins to increase RBC production
  • Become Hypercoagulable, so increased risk for thromboembolic events
  • Decrease in platelets and increase in WBC to accomidate growth of baby
  • Will see changes in EMG and may need to adjust electrodes due to growth of baby (may need to move to left)
  • Murmers may be detected
  • Increase in HR to accommodate for increased blood volume
37
