Contraception Flashcards
What is the Fertility Awareness method?
The awareness of the fertile period during a cycle and either abstaining or using the barrier method during that time
State the four subtypes of Fertility Awareness
Standard Days
Cervical Mucous
Basal Body Temp
Sympothermal
Describe the ‘Standard Days’ subtype of Fertility Awareness
If your cycle is between 26 and 32 days long, days 8-19 are the most fertile
Describe the ‘Cervical Mucous’ subtype of Fertility Awareness
Just prior to ovulation the oestrogen levels increase which makes the mucous thin and stretchy to optimise fertilisation
Be aware that intercourse/breast feeding/female hygiene products can falsely alter
Describe the ‘Basal Body Temp’ subtype of Fertility Awareness
Temperature increase of atleast 0.2 degrees with an increase in Progesterone
Fertility peaks a few days before this (so not very efficient)
Describe the ‘Sympothermal’ subtype of Fertility Awareness
Combines Cervical Mucous and Basal Body Temperature
Describe the Lactational Amenorrhoea method
Full or almost exclusively breastfed
<6 months old
Menses not returned
Describe the pathophysiology of Lactational Amennorhoea
Prolactin supresses GnRH release from hypothalamus
FSH and LH decreases and therefore Oestrogen
What is the difference between Diaphragms and Caps?
Diaphragms should lie diagonally between pubic bone and posterior fornix
Caps sit directly over the cervix and must be left in place for 6-8 hours
What is the pathophysiology of the COCP?
Supresses FSH and LH hence decreasing ovulation
Thickens cervical mucous
Describe the two types of COCP
Monophasic - each pill contains the same amount of oestrogen and progesterone
Phasic - levels of hormones vary across the pills, therfore it is important they’re taken in order. Aims to reduce SE
Name 5 contraindications to the COCP
BMI>35 Breast Feeding Hypetensive Migraines with Aura Smoker aged > 35
What cancers does the COCP decrease the incidence of, and what do they increase the incidence of?
Reduced risk of ovarian/uterine/colon
Increased risk of breast and cervical
Give three drug interactions of the COCP
Rifampicin
Anticonvulsants (Carbemazepine)
Antiretrovirals
Describe the pathophysiology of the Progesterone Onlly pill
Thickens cervical mucous and thins endometrium
