ESSENTIALS OF OBSTETRICS AND
GYNECOLOGY HACKER MOORE
COMPREHENSIVE STUDY QUESTIONS AND
ANSWERS
◉ What do FSH and LH stimulate in the ovaries?
Answer: They act on theca cells and granulosa cells.
◉ What is the role of granulosa cells in the ovaries?
Answer: They contain FSH receptors and convert androstenedione
to 17-beta-estradiol.
◉ What hormone is primarily produced during the follicular phase?
Answer: Estrogen
◉ What is the function of progesterone during the menstrual cycle?
Answer: It is responsible for uterine ripening to allow proper
implantation of a fertilized ovum.
◉ What occurs during days 14-28 of the menstrual cycle?
Answer: Progesterone predominates as the corpus luteum secretes
progesterone and estrogen.
,◉ What happens if the ovum is fertilized?
Answer: hCG is produced to maintain the corpus luteum, which
maintains the endometrial lining.
◉ What is the consequence of no fertilization of the ovum?
Answer: The corpus luteum involutes, leading to a decline in
progesterone and estrogen, resulting in menstruation.
◉ What triggers ovulation?
Answer: A sudden surge in LH.
◉ What is the implantation window in the menstrual cycle?
Answer: Days 20-23, when the endometrium is most favorable for
implantation.
◉ What is the average blood loss during menstruation?
Answer: 30-80 mL
◉ What defines menorrhagia?
Answer: Bleeding that lasts more than 7 days or blood loss greater
than 80 mL.
,◉ What is the most common cause of secondary amenorrhea?
Answer: Pregnancy
◉ What is the first step in diagnosing abnormal uterine bleeding in
reproductive-age women?
Answer: hCG test to rule out pregnancy.
◉ What imaging test is most commonly used for diagnosing
leiomyoma (fibroids)?
Answer: Transvaginal ultrasound.
◉ What are the clinical manifestations of leiomyoma?
Answer: Menorrhagia, dysmenorrhea, pelvic pressure/pain.
◉ What is the most common benign gynecological tumor?
Answer: Leiomyoma (fibroids).
◉ What is the role of estrogen during the proliferative phase of the
menstrual cycle?
Answer: It stimulates the thickening of the endometrium.
◉ What is anovulatory bleeding?
, Answer: Bleeding due to the ovaries producing estrogen without
ovulation, leading to unpredictable shedding.
◉ What is a luteal phase defect?
Answer: When ovulation occurs but the corpus luteum does not
produce enough progesterone.
◉ What is the significance of mid-cycle spotting?
Answer: It is related to a sudden drop in estrogen that destabilizes
the endometrial lining.
◉ What are the risk factors for developing leiomyoma?
Answer: Increasing age, especially in women of reproductive age.
◉ What is the treatment for acute hemorrhage due to dysfunctional
uterine bleeding?
Answer: IV high-dose estrogen or high-dose oral contraceptives.
◉ What does a positive progestin challenge indicate?
Answer: It indicates that the patient likely has PCOS (Polycystic
Ovary Syndrome).
