menstruation Flashcards
Menstruation
shedding of the endometrium; no
fertilization of ovum
menarche
first menstruation
amenorrhea
absence of mestruation
primery:never had a mestraution
secondary: had it but stoped for period of time
-ex: weightloss
Menstrual Cycle
- Regulated by fluctuating hormones
- Length: 21-36 days
* 4 phases( what are the hormons,ovaries and uteurs doing?)
Menstrual Phases
1st Phase: Proliferative or Follicular Phase - less fertile
* Variable in length
2nd Phase: Ovulatory Phase
3rd Phase: Secretory or Luteal Phase
* 14 days
4th Phase: Menstrual Phase
1st Phase: Proliferative or Follicular Phase
5-13 days
- the pituitary secretes relatively high levels of FSH.
- stimulate follicles in the
ovaries. - it signals one follicle in the ovaries to bring an egg to the final stage of maturity.
- At the same time, the
follicle >+ estrogen
2nd Phase: Ovulatory Phase
14 day
- **the follicle ruptures open, releasing the mature egg **
- estrogen has risen to a high level, so - FSH
- estrogen also > the hypothalamus to produce+ GnRH, which
causes the pituitary to begin production of LH.
- estrogen also > the hypothalamus to produce+ GnRH, which
- A surge of LH triggers ovulation.
3rd Phase: Secretory or Luteal Phase
15 to end of cycle (28)
After releasing an egg, the follicle, under stimulation of LH, > corpus luteum
. The corpus luteum > + progesterone, ,- LH
the corpus luteum degenerates.
- estrogen and - progesterone
- estrogen stimulate the pituitary > + FSH, and the whole cycle begins
again.
4th Phase: Menstrual Phase
menstruation is a
shedding (the endometrium), which then passes out through
the cervix and the vagina.
During this phase, **- estrogen **and - progesterone levels and are
**FSH levels are rising. **
Menstruation is triggered by the sharp decline in estrogen and
progesterone levels at the end of the luteal phase
Hormonal Birth Control
The Combination Pill (Alesse, Yasmin, Tri Cyclen)
- Contains both estrogen & progestin (synthetic progesterone)
- hormones for 21 days, then no pill or sugar pill for 7 days
- Pill works by preventing ovulation
- Pill maintains more consistent hormone levels (i.e., no peak in
estrogen, no ovulation)- confuses feedback loop

What are the recent
advancements in male birth
control?
- people drop out because of side effects
- acne,headcques,weight gains(similar to women)
- but for women pregancy is major issue but for men not so much
-gel blocker/vacine (not sergery vasectomy)
Menstrual Problems: Dysmenorrhea
- pain or discomfort (typically cramps)
primary – no organic origin
**secondary ** – pain secondary to organic
problems (e.g., endometriosis, ovarian cysts,
etc.)
cramps (uterine contractions)
from
prostaglandins
Menstrual Problems:mastalgia
fluid retention; in breasts
orgasm can help with mestruation pain
brings blood cutted of and increses endorphines
