UNIT 3- REPRODUCTION CONTRACEPTION & INFERTILITY Flashcards
In pubery the hypothalamus secretes what hormones?
- Gonadotropin-releasing hormone (GnRH)
In puberty the anterior pituitary secretes what hormones?
- Follicle-stimulating hormone (FSH)
- Leteinizing hormone (LH)
During puberty what is happening with the ovaries and testes doing?
Increasing production of sex hormones (gametes)
Male and female reporductive systems are similar in utero for how long?
until the 1st 6 weeks
What secretes the primary sex hormones?
Ovaries and testes
During childhood the sex glands are…. active or inactive
inactive
When do reporductive organs become functional?
Puberty
What should we know about puberty changes in males?
(when does it happen, what triggers it, and what secondary sex characteristics will we see?)
- Puberty- capable of reproduction- 13.5 y/o age
- Triggered by the production of testosterone
- secondary sex characteristics
- Skeletal growth
- increases in body composition
- devleop body hair- facial, axillary and pubic
- Voice changes
- Enlargment of testes and penis
- noctural emissions (wet dreams) not usually mature sperm tho
What should we know about female puberty changes?
(when does it happen, what triggers it, and what secondary sex characteristics will we see?)
- Puberty- capable of reproduction- 8-13 y/o age
- Triggered by the production of estrogen
- Secondary sex characteristics
- Develope body hair-axillary, legs & pubic area
- Body contours-widening of hips
- Skeletal growth
- Reproductive organs
- Breast changes- mamary ducts & nipples erect
- 1st menstrual period-2-2.5 years after puberty
What are the structures of a female reproductive system?
- Ovaries
- Fallopian tubes
- Uterus
- Cervix-internal and external os
- Vagina
The anterior pituitary hormone FSH’s function is?
Helps control menstrual cycle & production of eggs by ovaries
The anterior pituitarys hormone LH’s function is
A surge causes ovulation and results in formation of corpus luteum
The ovaries release estrogen and its funciton is?
- THickens uterine lining and regulates growth, development & physiology of reproductive system
The ovaries release progesterone and its function is?
- Prepares the lining of the uterus to impant and grow a fertilized egg; inhibits FSH & LH
What are the 4 phases of the menstrual cycle?
- Menstrual phase
- Proliferative phase
- Ovulatory phase
- Luteal phase
In the menstrual cycle what is the menstrual phase?
- Day 1 to Day 5
- changes we might see- mood swings, tender breast, cravings, irritable
In the menstrual cycle what is the proliferative phase?
- Day 5-14 end of menstral- pituitary secretes FSH which makes the egg, LH which houses the egg and starts produceing progesterone
In the menstrual cycle what is the ovulatory phase?
- This is where your best shot of pregnancy occurs- marked increase in the LH and FSH hormone, getting ready for egg.
- Only 1 egg per month
Think 0 for egg
In the menstrual cycle what is the luteal phase?
- During this phase, levels of FSH and LH decrease in response to higher levels of estrogen and progesterone. If the ovum is fertilized it secreats a hormone that causes persistence of corpus luteum to maintain an early pregnancy
- If the ovum is not fertilized, FSH and LH fall to low levels and the corpus luteum regress.
- Decline of estrogen and progesterone along with corpus lutum regression results in menstrauation as the uterine lining breaks down.
The menstrual cycle is caused by
hormone changes
What are the 4 phases in the endometrial cycle?
- menstrual phase
- Proliferative phase
- Secretory phase
- Ischemic phase
The endometrial cycle is driven by…
What is happening to the lining physcially
In the endometerial cycle what is the menstrual phase?
Vasocontriction and shedding of the lining which sloths off
In the endometrial cycle what is the proliferative phase?
- Occurs as the ovum matures and is released during the first half of the ovarian cycle. After completion of a menstrual period, the endometrium is very thin. The basal layer of the endometrial cells remain after menstration. These cells multply to form new endometrial epithelium and endometral glands under the stimulation of estrogen secreated by the maturing ovarian follicles. Endometrial sprial arteries and endometerial veins elongate to accompany thickening of the functional endometrial layer and nourish proliferating cells. As oculation approches, the** endometrial glands secrete thin, stringy mucus that aids entry of sperm into the uterus.**
In the endometrial cycle what is the secretory phase?
- The secretory phase occurs during the last half of the menstrual cycle as the uterus is prepared to recieved a fertilized ovum. The endomentrium contines to thicken under the influence of estrogen and progesteron from the corpus luteium. Reaching its maxium thickness.
- If pregnancy does not occur lining will be shed off again
In the endometrial cycle what is the ischemic phase?
Vasospasm of the endometrial blood vessels causes the endometrium to become ischemic and necrotic. THe necrotic areas of the endometrium separate from basal layers, which results in the menstrual flow.
What conditions must be met for fertilization to happen?
1.Fallopian tubes are patent
2.Semen is supportive to pregnancy
3.Adequate progesterone & thickening endometrium of uterus(endometrial biopsy)
4.Live,motile, normal sperm are present (postcoital test)
What are signs of ovulation?
- Drop in basal body temp: Occurs 1 day before ovulation and remains elevated 10-12 days
- Spinbarkeit Mucus: abundant, watery thin, clear, stretchy (egg white)
- Cervical os dilates slightly, softens and rises in the vagina
- Mittelschmerz occurs: localized abdoinal pain
- Saliva ferning: seen under microscope
- Increased libido
What is spinnbarkeit mucus?
Abundant, watery thin, clear stretch (eggwhite) mucus
What does the cervical os do during ovulation?
Dilates slightly, softens and rises in the vagina
What is Mittelschemez?
Localized abdominal pain during ovulation
usually on one side and occurs about 14 days before the next period
While educating a patient on the reporductive cycle, the nurse should plan to inculde that ovulation occurs when the….
blood level of LH is too hihgh

- Anatomic abnormalities such as varicocele (enlargment of veins behind teste, absence of a teste)
- Exposure of toxins such as lead, pesticides or other chemicals
- Antineoplastic drugs– chemo or radiation
- Excessive alcohol intake; use of illicit drugs-effects sperm motility
- elevated scrotal temps
- Immunologic factors produced by man or women
How can abnormal ejection in men cause infertility?

- systemtic disease
- abnormalities in ovaries or other endocrine glands- polyps cause scaring which creates a hostile cervical mucus so instead of thinning it might thicken
What abnormalities of the fallopian tubes can cause infertility in women?
- Endometriosis- tissue lining has grown outside of the uterus where it does not belong
What abnormalities in the cervix can cause infertility in women?
- Estrogen levels decreased preventing the developement of spinnbarkeit- if this is decreased we have thick cervical mucus which causes sperm to not be able to travel
