- A lump is often present
-May have bloody nipple discharge

53
Q

The male being the cause of infertility accounts for what percentage of infertility cases? What diagnostic should be done for this? What is the normal ejaculate volume and stats?

A

40%

semen analysis

Normal volume: 1.5-5mL and pH > 7.2

54
Q

If amenorrhea is secondary to a hypothalamus problem, what labs are seen?

A

Normal/decreased FSH/LH
Decreased Estradiol
Normal Prolactin

55
Q

The menstrual cycle varies from _______ and the average time is ______. Menstruation is considered what “day” of the cycle? Ovulation occurs________

A

Varies from 20-25 days
Average is 28 days
Menstruation is day 1
Ovulation occurs 14 days before menstruation

56
Q

Explain the H-P-O axis and the hormones that control each phase.

A

Pulsatile GnRH from Hypothalamus –> FSH and LH from anterior pituitary –> control ovary follicles

57
Q

Explain what happens in the pre-ovulatory phase (2 weeks leading up to ovulation). Give both names, explain the hormones, what occurs, etc.

A

Ovarian Follicular Phase & Endometrial Proliferative Phase

Estrogen predominates and builds up endometrium

-GnRH –> increases FSH and follicle/egg maturation in ovary. Increased LH causes follicle to produce estrogen. Ovulation occurs on day 12-14 and then positive feedback causes more GnRH, more estrogen, LH and FSH

58
Q

At the last step in the pre-ovulatory phase, what causes ovulation (Days 12-14)?

A

Sudden LH surge

59
Q

Explain what happens in the next phase (Post-Ovulatory) which is Days 14-28. What are the two names, what hormones do what, etc.

A

Ovarian Luteal Phase and Endometrial Secretory Phase

Progesterone predominates

LH surge causes follicle to become corpus lute which secretes estrogen and progesterone to maintain endometrium.

If the follicle is NOT fertilized, corpus luteum deteriorates and the fall of estrogen and progesterone leads to menstruation. Process starts all over.

60
Q

What is infertility in a female defined as? What medication can be used to treat this (as an option)?

A

Failure to conceive after 1 year of regular, unprotected sex

Clomiphene induces ovulation. Encourage diet and exercise to correct endocrine problems that may be causing this as well.

61
Q

What is the karyotype of Turner Syndrome and what is one thing it can cause related to OBGYN?

A

Female 45, XO

Amenorrhea

karyotyping gives the definitive diagnosis

62
Q

What is menopause defined as? What is the average age? What is considered premature? Explain some symptoms of this condition.

A

Cessation of menses > 1 year due to loss of ovarian function

Average: 50-52

Premature if < 40 years old

Hot flashes, vaginal atrophy, incontinence, osteoporosis, CV risk increases, decrease in breast size, sleep changes

63
Q

What is the most sensitive assay for menopause and what does it show?

What is the predominant estrogen AFTER menopause?

64
Q

What do the other labs show with menopause?

A

Increased FSH
Increased LH
Decreased Estrogen

65
Q

What is a leiomyoma? One important risk factor that should be remembered (a population that is at increased risk for this condition).

And what is the most common symptom of this.

A

Benign uterine smooth muscle tumor (MC benign gynecologic tumor)

African Americans at 5x more risk for this

Bleeding MC symptom

66
Q

What is one thing to remember about a leiomyoma in regards to the pathophysiology?
