Q

what happens 1 yr before puberty

A
  • nocturnal pulses of gonadotropin secretion—FSH and LH
  • incr resp in the pituitary to GnRH

results in stimualtion of gonadal maturation with ESTRADIOL and TESTOSTERONE secretion

A

30-50 mL

49
Q

If a woman is not using hormonal birth control, you can assume that ??

A

women are ovulating (releasing an egg) each time they have a period

50
Q

having a period means?

A

you are fertile

51
Q

two days before start of menses, what hormone increases

-what does this hormone cause

A

FSH

  • causes maturation of a group of ovarian follicles (oocytes/eggs)
  • dominant follicle emerges
52
Q

what marks the beginning of follicular phase

A

menses starting—-DAY 1 of cycle!!!

**egg/follcile is starting to mature and getting ready for ovulation

53
Q

during follicular phase, what hormone does the oocyte/follicle start to secrete?? what happens due to this hormone being secreted

A

it starts to secrete estradiol–>provides (-) feedback to PG to stop producing FSH (+) feedback to start incr LH

54
Q

which hormones are at its lowest during follicular phase

A

estradiol
LH
Progesterone

55
Q

what hormone is highest at the start of the menstrual cycle

A

FSH

56
Q

what is phase 2 of the reproductive cycle

A

ovulation

57
Q

Ovulation

-by day 11-13 of normal cycle, what happens

A

LH surge— triggers ovulation

58
Q

what triggers ovulation and what day of cycle

A

days 11-13= LH SURGE

59
Q

after LH surge, what happens during ovulation

A

Oocyte is expelled from follicle

60
Q

where does the expelled oocyte travel to next

A

fallopian tubes–>uterus–>awaiting fertilization

61
Q

after expulsion of the oocyte, what does the empty follicle turn into?

A

corpus luteum

62
Q

define ovulation

A

mature egg or oocyte released from follicle in the ovary

63
Q

what is the follicle

A

protective sac around the egg giving the maturing egg nutrients and protection

64
Q

what is left behind after ovulation

A

follicle– turns into corpus luteum

65
Q

follicular phase is dominated by?

A

estradiol

66
Q

luteal phase is dominated by?

A

progesterone

67
Q

after ovulation, how long does it take to produce progesterone

A

24 hours after ovulation

***rises rapidly thereafter

68
Q

when is the peak of progesterone

**maintained for how long?

A

3-4 days after ovulation

**maintained approx for 11 days

69
Q

what happens to progesterone levels if fertilization and implantation do not occur

A

progesterone production diminishes rapidly

70
Q

what is making the progesterone

A

corpus luteum

71
Q

“prime” time to get pregnant

A

2-4 days after ovulation—oocyte is now in uterus waiting for fertilization

72
Q
  1. surge in LH=?
  2. day 1 of menstrual cycle, the highest hormone=?
  3. what happens after egg is released?
A
  1. ovulation
  2. FSH
  3. corpus luteum makes progesterone—the egg that would be fertilized and implanted needs progesterone to IMPLANT
73
Q

why does a fertilized egg need progesterone

A

to implant into endometrium and sustain the pregnancy into early first trimester

74
Q

life span of corpus luteum

A

13-14 days unless pregnancy occurs

75
Q

if oocyte becomes fertilized and implants within endometrium— early pregnancy begins secreting?

A

Human Chorionic Gonadotripin (hCG)

76
Q

what does hCG do early on in pregnancy

A

sustain the life span of corpus luteum for another 6-7 weeks—-so progesterone continues to be produced

77
Q

progesterone produces ____ feedback to PG to ____ levels of what hormone(s)

A

progesterone provides negative feedback on PG–>both FSH and LH levels are suppressed

78
Q

what happens when corpus luteum gets HCG hormone

A

it sustains the life of the corpus luteum for another 6-7 weeks so more progesterone can be secreted to sustain early pregnancy

79
Q

what happens when progesterone levels fall due to egg not being fertilized?

A

FSH begins to rise—- preparing woman for another reproductive cycle

80
Q

what inhibits FSH and LH

A

Progesterone

81
Q

what hormones are highest at days
7
14
21

A

7= FSH

14=LH

21=progesterone

82
Q

ammenhorrhea define

A

absence of menstruation

83
Q

primary amenhorrhea define

A

menarche has not occured by age 13-15

84
Q

causes of primary amenorrhea (3)

A
  1. anatomical defects—absence of vagina and uterus
  2. genetic disorders–Turner syndrome
  3. problems with AP—tumors or problems with CNS that affect hypothalamic defects—prevents release of GnRH–which means no signaling of AP to release FSH and LH
85
Q

how to diagnose primary amenorrhea

A

labs–abnormal levels of gonadotropins or ovarian hormones or precense of genetic conditions

diagnositc imaging–US and MRI`

86
Q

tx for primary amenhorrhea

A

correction of underlying disorders and implementation of HRT

surgery only to correct structural abnormalities

87
Q

number one cause of secondary amenohorrhea

A

pregnancy

88
Q

define secondary amenorrhea

A

absense of menstration for a time equivalent to three or more cycles in women who have previously menstruated

89
Q

how many cycles missed to call it secondary amenorrhea

A

THREE+

90
Q

causes of secondary amenorrhea (7)

A
  1. PREGNANCY *****
  2. hypothryoidism
  3. hyperprolactinemia
  4. excessive exercise
  5. stress
  6. weight loss
  7. PCOS
91
Q

define dysmenhorrhea

A

painful menstruation

92
Q

s/s of dysmenorrhea

A
  • pelvic pain associated with onset of menses
  • backache
  • anorexia
  • vom/dia
  • syncope
  • HA
93
Q

what is causing HA with dysmenorrhea

A

prostaglandins enter the systemic circulation

94
Q

define primary dysmenhorrea and what causes it pathophys wise

A

-painful menstruation caused by release of prostaglandins in NORMAL OVULATORY CYCLE

95
Q

prostaglandin is a vasodilator or contrisor

A

vasoconstrictor–constricts endometrial BVs a

96
Q

prostaglandin is myometrial inhibitor or stimulant

A

stimulant—increases myometrial contractions

97
Q

pathophysiology to the pain caused in dysmehorrhea

A

prostaglandin is released into systemic circulation–>excess prostaglandin increases myometrial contractions, constricts endometrial BVs and enhances nerve hypersensitivity——–results in PAIN

98
Q

primary dysmenorrhea always correlates to?

A

menses

**ovulatory cycle is releasing the prostaglandins causing the pain **

99

101
Q

secondary dysmenorrhea has no correlation to?

A

period

wherehas primary always correlates to period

102
Q

tx for primary and secondary dysmenorrhea

A
  1. NSAIDS—– reduce COX enzyme activity–>reducing prostaglandins
  2. hormonal contraception—stops ovulation and creates atrophic endometrium—-decring prostaglandin synthesis and myometrial contractility
