Couple looking for permanent contraceptive strategies
Background
Male reproductive system
Penis
Erectile tissue
Fills with blood to for an erection
Urethra
Carries urine and semen outside the body
Corpus cavernosa
Facilitate penile erections
Corpus spongiosum
Prevents the urethra from pinching closed
Testis
Epididymis
Transports and stores sperm cells
Ductus deferens
Transports sperm cells from the epididymis
Scrotum
Protective and acts as a climate control
Female reproductive system
Vagina
Posterior fornix
Separates lumen of vagina from the pouch of douglas
Lumen of vagina
Anterior fornix
Leads to arousal when stimulated
Uterine tube
Infundibulum
Catches and channels the released eggs
Fimbriae
Move eggs down fallopian tube
Ovary
Produce oocytes and reproductive hormones
Uterus
Perimetrium
Protects uterus from friction
Cervix
Allow flow of menstrual blood and direct sperm into uterus
External genitalia
Mons pubis
Role in secreting pheromones
Clitoris
Pleasure center
External urethral orifice
Where urine exits
Greater vestibular gland
Secrete mucous to lubricate vagina
Labium minus
Protective structure that surround the clitoris, urinary, and vaginal orifice
Labium majus
Protects inner structures
Ovarian cycle
FSH and LH are released
Hormones stimulate the growth of about 15 to 20 eggs in the ovaries each in its follicle
FSH an LH also trigger an increase in the production of estrogen
Estrogen levels rise turning of the production of FSH
One follicle in the ovary continues to mature
Luteal phase
Once it releases egg, empty follicle develops into the corpus luteum
Corpus luteum makes progesterone preparing the uterus for a fertilized egg
Fertilized egg will travel through the fallopian tube to implant in uterus
If egg is not fertilized, it passes through the uterus
Uterine cycle
Menstrual phase
Uterus sheds all but the deepest part of its endometrium
The thick functional layer of the endometrium detaches from the uterine wall
Detached tissue and blood pass out through the vagina as the menstrual flow
Day 4, growing ovarian follicles start to produce more estrogen
Proliferative phase
The basal layer of the endometrium generates a new functional layer
As this new layer thickens, its glands enlarge and its spiral arteries increase in number
Estrogen also induce the endometrial cells to synthesize progesterone receptors
Rising estrogen levels cause the cervical mucous to become thin and form channels that facilitate sperm passage into the uterus
Secretory phase
Tissue regrowth is completed
Makes the possibility of pregnancy and the implantation of a fertilized egg
Contraceptive methods
Pill
Hormones in pill stop ovulation
Potential side effects
Missed periods
Intermenstrual spotting
nausea
Tubal ligation
Fallopian tubes are cut, tied or blocked to permanently prevent pregnancy
Potential side effects
infection
Damage to other organs inside abdomen
Male condom
Stops sperm from meeting an egg
Potential side effects
Latex allergy
Aren't foolproof
IUD
Creates changes in the cervical mucous killing sperm inside uterus or makes them immobile
Potential side effects
Irregular bleeding for several months
Infection
Vasectomy
Blocks each vas deferens tube keeping sperm out of semen
Potential side effects
Blood in semen
Infection of the surgery site
Downstream
3 worst strategies
Pill
99% effective if taken everyday
Weight gain
Mood changes
Sore or swollen breasts
Condoms
85% effective
Can break
Can cause a latex allergy
Expensive
Contraceptive jelly
70% effective
Can cause infections
Must be used correctly
3 best strategies
Tubal ligation
Permanent
Doesn't affect hormones
Don't need to constantly worry about pills or condoms
Possible side effects
Can lead to ectopic pregnancy
Surgery can cause bleeding or damage bowels
IUD
Low maintenance
99% effective
Can't feel it
Possible side effects
Cramping, spotting, heavy bleeding
Rarely slips out of place
Vasectomy
99% effective
Less likely to cause problems than a woman having her tubes tied
Less expensive
Possible side effects (rare)
Discomfort in a testicle
Spermatocele
Hydrocele
Upstream
No change in hormones
Making it permanent
No change in sex drive
