Womens Health Flashcards
What does follicular stimulating hormone (FSH) do?
- Spurs follicle development and causes estrogen surge
*peaks on 14th day, triggers ovulation and locate release
What does estrogen and progesterone do to the uterus?
- The endometrium will thicken for an embryo
What happens to the uterus when estrogen and progesterone is low during the menstrual cycle?
- The blood sloughs off the lining causing spotting
What does progesterone do to the cervical mucus?
- Will thicken the cervical mucus and body temperature will increase
What does estrogen do to luteinizing hormone (LH) and follicular stimulating hormone (FSH)
- Estrogen causes LH and FSH to surge
What does the surge of LH and FSH do?
- Causes the oocyte (egg) to release from the ovary into the fallopian tube
*egg lives here for 24 hours once released
What do you need to trigger ovulation?
LH and FSH
What is the MOA of hormonal contraceptives?
- They will inhibit production of FSH and LH to prevent ovulation
- They alter cervical mucus, inhibiting sperm from penetrating egg
What are the different types of hormonal contraceptions /
- Combined oral contraceptives (COCs)
*Estrogen + Progestin - Progestin only
- Non-oral combined hormonal
What do combined hormonal contraceptives contain? (COCs)
- Estrogen ethinyl estradiol (EE) and a progestin
What are the different formulations of combination oral contraceptives?
- Monophasic
*Same dose of estrogen and progestin throughout the pack - Biphasic, triphasic, and quadriphasic
*mimic estrogen and progesterone levels during menstrual cycle
What does Lo mean for combined oral contraceptives?
<35mcg estrogen, which means there is less estrogen to cause less estrogenic side effects
What does Fe mean? For combined oral contraceptives
An iron supplement is included
What does 24 mean for combined oral contraceptives
There is a shorter placebo time (EX 24 active + 4 placebo = 28 d cycle)
What is Lo loestrin Fe?
This combined oral contraceptive is the lowest dosed estrogen on the market
*10 mg
What will extended cycle COCs have? (Period every 3 months)
- There will be >21 days of active hormone
*will minimize blood loss
*may improve menstruation-related problems (dysmenorrhea)
*eliminated withdrawal bleeding
What type of pills are recommended for extended cycling?
- Monophasic pills (same dose of estrogen and progestin throughout the pack)
*there is an increased risk for breakthrough bleeding with others
What would women do prior to the development of extended cycle COCs?
- Women on standard 21/7 days packs could choose to “skip a period” by not taking the placebo pills
What are the progestin only oral contraceptives?
- Mini pills
*Errin
*camilla
*Nora BE - Norethindrone 35mcg
How can progestin only OC be taken?
- Taken daily with no placebo or pill free interval
- Can start on any day of the cycle, just keep timing consistent
How long does it take for progestin only OC to start working?
- Works within 48 hours
*If you miss a dose >3 hours use an alternative contraception for the next 48 hours
How do hormonal contraceptive primarily work by?
Inhibiting the production of LH and FSH
*inhibiting them will prevent ovulating by altering cervical mucus. Which will prevent the sperm from reaching the egg
What hormones are contained within a combined hormonal contraceptive?
- Progestin
- Estradiol (Estrogen)
What are the synthetic estrogens?
- Ethinyl estradiol
- Mestranol
- Estradiol valerate
What is primary amenorrhea?
Absence of spontaneous menstruation by 15 years old thereafter
What is secondary amenorrhea?
- Prior normal menses and absence of menses for 90+ days
OR - Irregular menses and absent for 6+ months
What are the common causes of secondary amenorrhea?
- Pregnancy
- MC for women in competitive sports
What do you need to rule out when a patient presents with amenorrhea?
- Pregnancy (get and hCG)
