Only thing that protects against STIs
Condoms
27
Good condoms have what
Reservoir tip
28
Diaphragms are used how , used how, side effect
Latex + spermicide dome shaped up in vagina 6-8 hours before and after intercourse (not more then 24hours)
= have to be fitted by health care provider
= higher UTI infections (compression of urethra) + vaginitis from spermicide
29
Single size fit all Diaphragm
Chaya ( you can put in out yourself and no health care provider needs to fit you)
30
Cervical Cap (FemCap)
Smaller then diaphragm and put on cervix no more then 48hr, high risk of displacement, use with spermicide
31
Sponge
Pillow shapes containing spermicide, dimple fitting over cervix, left for 6 hours only not more then 30hrs, more effective in nullparous woman (toxic shock syndrome high risk)
32
Phexxi
Hormone free, raising pH of vagina, lactic acid + citric acid + Potassium bitartate gel, prescription only, 84% effective, 4 hours lasting
= risk of UTI, vaginitis, burning, itching , infections
33

0.5 to 1.0 degree increase at ovulation avoid sex 3 days after (check in morning)
34
Cervical mucous method
Cervical mucous changes around ovulation avoid sex 4 days after (Spinnbarkeit)
35
Symptothermal method
Combing basal temp method and cervical mucus

42
Laparoscopy of female sterilization
| 4 types and how they are done, failure rate and rate of being reversed
Small incisions, low complications,
1. Electrocautery (thermal injury, low reversibility, higher ectopic preg risk)
2. Clips ( hulka - more reversible + higher failure, Filshie - lower failure + lower reversibily)
3. Bands (falope rings = intermediate reversible and failure, post op pain + increases bleeding risk)
4. Salpingectomy = remove Fallopian tubes, decrease ovarian cancer risk
43
Mini Laparotomy
MOST COMMON
1. Small infra umbilical incision postpartum or suprapubic (interval procedure)
2. Transect part of the Fallopian tube or all of wanted
