• Teenage fertility rate of 87 births per 1000 in some rural & remote areas
• The estimated abortion rate at 19 per 1000 women
• The Netherlands abortion rate of 8.7 per 1000 women

Contraceptive CHOICE study
• US prospective cohort study of 9256 women age 14 – 45yo
• Participants read a script regarding long-acting reversible methods of contraception to increase awareness of these options:
• Copper intrauterine device
• Hormonal intrauterine device
• Contraceptive Implant

False
• Exclude Chlamydia & gonorrhoea at time of insertion
• Risk of PID is only at time of insertion
• Presence of IUD doesn’t increase later PID risk

IUDs should not be inserted in nulliparous women

False!
• Pain? • Studies quote average pain for nulliparous women from 3-7/10
at insertion (similar to multiparous women)
• Recent US study suggests 20% young nulliparous women have moderate-severe pain a week later
• Same study - 83% satisfied or very satisfied with IUD

All hormonal contraception causes weight gain
• True
• False

False
• Depot contraception is the only method associated with weight gain; only in already overweight women
• Women using other methods gain weight…at the same rate as women not using hormonal contraception

USING MEC – can she use this method?
MEC 1 Yes e.g. nulliparous and IUD
MEC 2 Probably e.g. personal history venous thromboembolism and progestogen only method (e.g. contraceptive implant or injection, hormonal IUD)
MEC 3 Probably not – consider other method Needs careful consideration and good reasons why other methods inappropriate
e.g. a women aged ≥35 y who smokes less than 15 cigarettes per day and combined hormonal method
MEC 4 No
e.g. history of migraine with aura within last 5 years and combined pill

Question
• Contraceptive implants should be inserted in the sulcus between the bicep and triceps muscle
• True
• False

FALSE: AVOID THE SULCUS!
• June 2016: FSRH Clinical effectiveness unit: AVOID the sulcus
• Risk of intravascular insertion (rare)
• Inner side non-dominant arm about 8-10cm above the medial epicondyle of humerus
• OVER the triceps muscle posterolateral to sulcus

Initiating a LARC conversation:
• Explain methods briefly
• Highlight key benefits of:
High efficacy
Convenience
Reversibility
• Show a picture or use a model of the implant and IUD
• How/when she can access LARC insertion?

Explaining bleeding with progestogen-only LARCs
• Provide accurate information about expected bleeding patterns, emphasising that troublesome bleeding is likely to improve with time
• Be proactive in offering management advice for troublesome bleeding • Actively encourage review of troublesome
bleeding

Implanon bleeding - “unpredictable”
• 1/5 amenorrhoea (explain that this is safe and is caused by a thin endometrium)
• 3/5 infrequent, irregular bleeding
• 1/5 frequent or prolonged bleeding (explain around half will improve after 3 months)*
• Explain that management is available for troublesome bleeding and actively encourage review

Depot and progestogen IUD – “often to begin with, but it settles”
• Hormonal IUD: frequent spotting/bleeding common in first 3-5 months; either amenorrhoea, light irregular or light regular bleeding common after six months.
• DMPA Injection: ½ amenorrhoea, 1/6 infrequent irregular bleeding, 1/3 frequent/prolonged bleeding; amenorrhoea increases over time.

•Less evidence for effectiveness:
• Norethisterone 5mg tds for 21 days
• Levonogestrel progestogen only pill, 30 mcg bd for 20 days
• Early removal and replacement of implant or hormonal IUD, or shortening interval between injections from 12 to 10 weeks

COCP
•Start with lowest oestrogen and progesterone dose for the individual women which:
is well tolerated
has the best safety profile
is affordable
offers additional non-contraceptive benefits if desired
