28 days

Average menstrual cycle

secondary amenorrhea

Cessation of menstruation characteristically diagnosed in post menopausal woman 3-6 months without a menstrual cycle.

AUB (abnormal uterine bleeding)

Change in menstrual bleeding associated with lesions in uterus

Structure noted within Graafian follicle containing the developing ovum is

Cumulus oophorus

Periovulatory phase of uterine cycle

Distinct 3 line sign. 6-10 mm

Follicular phase

Days 1-14

Follicular phase. Proliferative phase

polymenorrhea

Frequent regular cycles but less than 21 days.

hCG

hCG

Hormone produced by trophoblastic cells of early placenta to sustain pregnancy.

LH (luteinizing hormone)

metrorrhagia (intermenstrual bleeding)

Irregular menstrual bleeding between periods

Day 15-28

Luteal phase. Secretory phase.

Cryptomenorrhea

Monthly symptoms of menstruation w/o bleeding

Structure produces hormones hat directly act upon he endometrium to produce varying thickness and sonographic appearance

Ovary

Ovary. Follicular. Luteal. Endometrium. Proliferative. Secretory.

LH (luteinizing hormone)

Produced by anterior pituitary gland

Corpus luteum primarily releases

Progesterone

First phase of endometrial cycle

Proliferative phase

hypomenorrhea

Regularly timed menses but light flow

Esteogen

Released by ovary during proliferative phase stimulates endometrial thickening

luteal phase

secretory phase of uterine cycle

Early proliferative phase of uterine cycle

Thickening hypoechoic functional layer. 4-8mm

menses phase of uterine cycle

Thin and echogenic. Up to 4 mm

Menorrhagia (hypermenorrhea)

excessive loss of blood during a menstrual period

menometrorrhagia

excessive uterine bleeding during and between menstrual periods

day 14 of menstrual cycle
