- The young person is likely to begin or to continue having intercourse with or without contraceptive treatment.
- Unless he or she receives contraceptive advice or treatment, the young person’s physical or mental health are likely to suffer.
- The young person’s best interest requires the practitioner to give contraceptive advice or treatment without parental consent.

32
How does the combined oral contraceptive pill work?
Inhibits ovulation as they suppress the release of LH and FSH
Some secondary actions:
Progesterone thickens cervical mucus
Progesterone inhibits endometrial proliferation, reducing the chance of successful implantation
33
Why are intrauterine coils UKMEC2 in women under 20?
They may have a higher rate of expulsion
34
Effectiveness of condoms?
98% effective with perfect use
82% effective with typical use
35
What condoms can be used in a latex allergy?
Polyurethane condoms
36
How do diaphragms and cervical caps work?
silicone cups that fit over the cervix and prevent semen from entering the uterus. The woman fits them before having sex, and leaves them in place for at least 6 hours after sex. They should be used with spermicide gel the further reduce the risk of pregnancy
37
What are dental dams?
Latex or polyurethane sheets used between the mouth and vagina/anus during oral sex
38
Benefits of COCP?
Usually makes period sregular, lighter and less painful
Reduces risk of ovarian and endometrial cancer and these effects may last for several decades after cessation
Reduced risk of colorectal cancer
May protect against PID
May reduce ovarian cysts, benign breast disease and acne vulgaris
39
Risks of COCP?
Forgetting to take it
No protection against STIs
Increased risk of VTE
Increased risk of breast and cervical cancer
Increased risk of stroke and IHD
40
Possible SE of COCP?
Headache
Nausea
Breast tenderness
Some users report weight gain but Cochrane review did not support this
41
COCP and concurrent antibiotic use?
Recent change to no need to use extra protection
Precautions should still be taken with enzyme-inducing antibiotics e.g. rifampicin
42
When do you require additional contraception when starting COCP?
If you start at any point in the cycle other than the first 5 days then you require additional contraception for the first 7 days
43
How should the COCP be taken?
Take at the same time every day
Conventionally taken for 21 days and then stopped for 7 days but it was realised there was no medical benefit from having a withdrawal bleed
Options include never having a pill-free interval or ‘tricycling’ - taking 3 x 21 day packs back to back before having a 4-7 day break
44
Situations where efficacy of the COCP may be reduced?
If vomiting within 2 hours of taking COCP
Medication that induces diarrhoea or vomiting e.g. orlistat
If taking lover enzyme-inducing drugs
45
What should you advise a woman to do if 1 COCP is missed at any time in the cycle?
Take the last pill even if it means taking 2 pills in 1 days and then continue taking 1 pill a day
No additional contraception protection is required
46
What should you advise a woman to do if 2 or more COCPs are missed at any time in the cycle?
Take the last pill even if it means taking 2 pills in 1 day, leave any earlier missed pills, and then continue taking 1 pill a day
Use condoms or abstain from sex until she has taken pills for 7 days in a row
If pills are missed in week 1 - emergency contraception if had intercourse
In week 2 - ok after 7 consecutive days of taking COCP
Week 3 - finish current pack and start new pack the next day i.e. skip pill-free interval
47
What does microgynon contain?
Ethinylestradiol and levonorgestrel
48
What does loestrin contain?
Ethinylestradiol and norethisterone
49
What does cilest COCP contain?
Ethinylestradiol and norgestimate
50
What does Yasmin COCP contain?
Ethinylestradiol and drospirenone
51
What does marvelon COCP contain?
Ethinylestradiol and desogestrel
52
First line COCP choice? And why?
A pill containing levonorgestrel or norethisterone e.g. microphone or leostrin
This is because they have a lower risk of VTE
53
Which COCP is considered first line for premenstrual syndrome? Why?
Yasmin as it contains drospirenone
Drospirenone has anti-mineralocorticoid and anti-androgen activity and may help with symptoms of bloating, water retention and mood changes
(May be more effective if used continually rather than cyclically)
54
Which COCP is good for treatment of acne and hirsutism e.g. in PCOS?
Why?
How long is it used for and why?
COCPs containing cyproterone acetate (“co-cyprindiol) e.g. dianette
Cyproterone acetate has anti-androgen effects
Usually only used for 3 months after acne is controlled as it has nearly 2x risk of VTE than other COCP
55
Side efefcts of COCP?
Unscheduled bleeding - common for first 3 months
Breast pain and tenderness
Mood changes and depression
Headaches
56
When should you stop COCP before surgery?
4 weeks before any major operation or any aperation that requires lower limb to be immobilised
To reduce thrombosis risk
A progestogen-only contraceptive may be offered as an alternative and the oestrogen-containing contraceptive restarted after mobilisation.
57
What is the only UKMEC4 for the POP?
Active breast cancer
58
What are the 2 types of progesterone-only pills?
Why is this relevant
Traditional POP e.g. norgeston or noriday
Desogestrel-only pill e.g. cerazette
Traditional POP cannot be called by more than 3 hours or it is considered a missed pill
Deogestrel-only pill can be taken up to 12 hours late and still be effective!
59
How do traditional POPs work?
They thicken the cervical mucus, alter the endometrium to make it less accepting of implantation and reduce ciliary action in the fallopian tubes
60
How does desogestrel-only pill work?
Inhibits ovulation
Thickens cervical mucus
Alters the endometrium
Reduces ciliary action in fallopian tubes
61
When starting the POP do you need additional contraception?
If you start it day 1-5 of menstrual cycle woman is immediately protected
If started any other time then additional contraception is required for 48 hours to allow cervical mucus to thicken enough to prevent sperm enterin the uterus
62
Switching between POPs
Can be switched immediately without need for any extra contraception
63
Switching from COCP to POP?
Immediately without additional contraception if they have taken the COCP consistently for >7 days or are on days 1-2 of the hormone-free period following a full pack of COCP
Otherwise it depends on whether they have had unprotected sex. If they have not since day 3 of the hormone-free period then they can start POP but require additional contraception for the first 48 hours. If they have had protected sex since day 3 of hormone-free period they should take COCP until they have taken 7 days consecutively and then they can switch over without any additional requimrent
64
Why is the woman not protected from pregnancy if she has unprotected sex on day 3 or later of the hormone-free period after taking COCP and then starts POP?
The POP does not reliably prevent ovulation and works mainly by thickening the cervical mucous. Sperm can live for 5 days in the uterus.
This means sperm can enter the uterus and live there for 5 days (until the 8th day after finishing the COCP). Taking the POP during this time will make no difference to the sperm already in the uterus, as they are already past the cervix. Then, if the woman ovulates on the 8th day after finishing the COCP, those sperm are there waiting to fertilise the egg.
65
Side effects of POP?
Unscheduled bleeding. Common for first 3 months - if longer then look for another cause
Breast tenderness
Headaches
Acne
66
How does POP typically affect periods?
20% have amenorrhoea
40% have regular bleeding
40% have irregular, prolonged or troublesome bleeding
67
What does POP increase the risk of?
Ovarian cysts
Small risk of ectopic pregnancy with traditional POPs (not desogestrel) due to reduce ciliary action in the tubes
Minimal increased risk of breast cancer, returning to normal ten years after stopping
68
What should you do after missing POP?
Take pill ASAP and continue with the next pill at the usual time
Then use extra contraception for the next 48 hours
If they have had sex since missing the pill or within 48 hours of restarting regular pills then emergency contraception is required
Episodes of d&v are managed as missed pills so extra contraception is required until 48 hours after D+V settle
69
What is the progestogen-only injection called?
Depot medroxyprogesterone acetate (DMPA)
70
How often is progestogen-only injection given?
Every 12 weeks
It can be given up to 14 weeks after last dose without need for extra precautions. BNF gives different advice and advises a pregnancy test if interval is >12 weeks and 5 days (not commonly adhered to)
71
How does the progestogen-only injection work?
It inhibits ovulation by inhibiting FSH secretion by the pituitary, preventing follicular development in the ovaries
Secondary effects: cervical mucus thickening and endometrial thinning
72
What are the 2 types of progestogen-only injection?
Depo-Provera: given by IM
Sayana Press: a subcutaneous injection device that can be self-injected by the patient
73
Why is DMPA 99% effective with perfect use but 94% effective with typical use?
Because women forget to book in for an injection every 12-13 weeks
74
Why is DMPA not a suitable contraception option for women who may wish to get pregnant in the near term?
It can take 12 months for fertility to return after stopping the injections
It’s not reversible once given
75
What is an alternative progestogen-only injectable to DMPA?
Noristerat - contains norethisterone and works for 8 weeks
Rarely used in clinical practcie
76
Contraindications to progestogen-only injectable?
UKMEC4:
Active breast cancer
UKMEC3:
IHD and stroke
Unexplained vaginal bleeding
Severe liver cirrhosis
Liver cancer
Women should generally switch to an alternative by age 50 due to the risk of osteoporosis
77
Timing the progesterone injection?
Starting on day 1-5 of the menstrual cycle = immediate protection and no extra contraception required
Starting after day 5 = 7 days of extra contraception
78
Side effects of the progesterone-only injection?
Irregular menstrual bleeding
Weight gain
Headache
Acne
Hair loss
Decreased libido
Mood swings
Skin reactions at injection site
79
Risks of progesterone-only injection?
Osteoporosis
Small increased risk of breast and cervical cancer
Small risk of infection at injection site or allergy
80
Why is the progesterone-only injectable associated with osteoporosis?
Suppressing the development of follicles = reduces amount of oestrogen produced = increased osteoclasts and enhanced bone resoprtion
81
What could you take alongside the porgestogen-only injectable if there is problematic bleeding?
COCP for 3 months to help settle the bleeding
Another option is a short/5 day course of mefanamic acid to halt the bleeding
82
Potential benefits of the progesterone-only injection?
Improved dysmenorrhea and premenstrual Sx
Improves endometriosis-related pain
Reduces risk of ovarian and endometrial cancer
Reduces severity of sickle cell crises in pt with SCA
Pt does not have to think about contraception for 12 weeks with DMPA
83
Name of the implantable contraceptive available?
Nexplanon
(This replaced Implanon to try to prevent deep insertions and the new one is now radiopaque and is therefore easier to locate if implapable)
84
What does the nexplanon implant release?
68mg Etonogestrel (a progestogen hormone)
85
Where are the nexplanon implants inserted?
In the proximal non-dominant arm, just overlying the tricep under the skin but a live the subcutaneous fat
86
How long do nexplanon implants last?
3 years
87
Mechanism of action of nexplanon implant?
Prevents ovulation
Also works to thicken cervical mucus and alters the endometrium to make it less accepting of implantation
88
Failure rate of nexplanon implant?
0.7/100 - most effective form of contraception
89
Disadvantages of nexplanon implant
Need for trained professional to insert and remove the device
Additional contraceptive methods are needed for the first 7 days if not inserted on day 1-5 of the woman’s menstrual cycle
Can lead to worsening of acne
No protection against STIs
Can cause problematic bleeding
Implants can be bent or fractured
Implants can become implapable or deeply implanted - may need investigation and additional management
Most expensive contraception annually
90
Advantages of nexplanon implant?
Effective and reliable
Can improve dysmenorrhea
Can make periods lighter or stop them altogether
No weight gain, effect on bone mineral density, increase i thrombosis risk or restrictions for use in obese pt
91
Adverse effects of nexplanon implant?
Irregular or heavy bleeding can occur (usually in 1/3rd infrequent bleeding, 1/4 worse bleeding and 1/5 no bleeding - rest normal)
Headache, nausea, breast pain
92
How can we help manage problematic bleeding as an adverse effect of nexplanon implant?
Using COCP for 3 months alongside it to help settle the bleeding (same as with injection)
93
What drugs may the nexplanon implant interact with?
Enzyme-inducing drugs e.g. certain antiepileptics and rifampicin - may reduce the efficacy of nexplanon
The advise is to switch method or use additional contraception until 28 days after stopping tx
94
Contraindications to nexplanon implant?
UKMEC4 - current breast cancer
UKMEC3: IHD and stroke, unexplained vaginal bleeding, past breast cancer, severe liver cirrhosis or liver cancer
95
What happens if the nexplanon implant becomes implapable?
Extra contraception is required until it is located
An USS or XR may be required to locate it. (It contains barium sulphate to make it radio-opaque)
In very very rare cases there are reports of devices entering blood vessels and migrating through the body, including to the lungs so you may consider a CXR if you cannot identify it
96
Which intrauterine device can be used for contraception, managing menorrhagia and HRT?
IUS
(Specifically mirena)
97
Mode of action of the IUD?
Prevents fertilisation by decreasing sperm motility and survival - copper ions are a hostile environment
98
How does the IUS work?
Contains levonorgestrel which prevents endometrial proliferation and causes cervical mucous thickening
99

Screening for chlamydia and gonorrhoea if woman is deemed high risk e.g. under 25
Bimanual exam to check position and size of uterus
Blood pressure and HR recorded before and after
102
How are the intrauterine coils inserted?

107
Risks relating to intrauterine coil insertion?
Temporary crampy period-type pain after insertion
Bleeding
Vasovagal reactions
Uterine perforation 2 in 1000 (higher in breastfeeding women
Proportion of pregnancies being ectopic are increased but absolute number of ectopic pregnancies is reduced compared to a woman not using conyrsaception
PID (only in the first 20 days)
Expulsion rate (most likely to occur in the first 3 months)
108
How do IUDs tend to impact periods?
They make them heavier, longer and more painful
109
How do IUSs tend to impact periods?
Initial frequently uterine bleeding and spotting
Later women typically have intermittent light menses with less dysmenorrhea
Some women become amenorrhoeic
110
What follow up is needed after insertion of an intrauterine device?
3-6 weeks later they need to be seen to check the threads
They will be taught how to feel the strings to ensure the coil remains in place
111
Risk of pregnancy before intrauterine coil removal?
Before the coil is removed, women need to abstain from sex or use condoms for 7 days, or there is a risk of pregnancy.
112
What 3 things need to be excluded when the coil threads cannot be seen or palpated?
Expulsion
Pregnancy
Uterine perforation
113
Managing non-visible or palpable coil threads?
Extra contraception until coil is located
USS
Abdominal/pelvic XR may be done to look for coil in abdomen or peritoneal cavity after a uterine perforation
Hysteroscopy or laparoscopic surgery may be required depending on location of coil
114
Benefits of copper coil?
Reliable contraception
It can be inserted at any time in the menstrual cycle and is effective immediately
It contains no hormones, so it is safe for women at risk of VTE or with a history of hormone-related cancers

Breastfeeding - avoid for 1 week after administration
Any gynae cancer or undiagnosed vaginal bleeding
135
Can you use more than 1 dose of ulipristal in the same menstrual cycle?
Previously it was not recommended however now this guidance has changes and it can be used > once
136
What is the most effective method of emergency contraception?
Copper IUD
137
When does the copper IUD have to be inserted if using for emergency contraception?
Within 5 days of UPSI or if later than it can be fitter up to 5 days after the likely ovulation date in the menstrual cycle
138
How does the copper IUD work for emergency contraception?
It may inhibit fertilisation or implantation
Copper is toxic to the ovum and sperm
139
First line emergency contraception?
How effective is it?
Copper IUD - >99% regardless of where it is used in the cycle
140
Why may antibiotics be considered when inserting a copper IUD?
Insertion may lead to PID, especially in women at high risk of STIs
141
How long should the copper IUD be in for if used as emergency contraception?
At least until the next period, after which it can be removed
Or it can be left in long term as contraception
142
Is male or female sterilisation more effective as contraception ?
Male
143
What is a vasectomy?
Male sterilisation
Cutting the vas deferens which prevents sperm travelling from the testes to join the ejaculated fluid which prevents sperm being released into the vagina
Performed under LA and is 15-20 mins and most men go home within a couple of hours
144
Follow up following a vasectomy?
Semen analysis needs to be performed twice following the vasectomy before a man can have unprotected sex. This is usually from 12 weeks post-procedure
145
Complications of vasectomy?
Bruising
Haematoma
Infection
Sperm granuloma
Chronic testicular pain - 5-30% of men
146
Success of vasectomy reversal and where can it be done?
Up to 55% if done within 10 years and 25% if after 10 years post procedure
Not on NHS so must be private
147
What is the procedure for female sterilisation?
Tubal occlusion
148
How is a tubal occlusion done?
This is typically performed by laparoscopy under general anaesthesia, with occlusion of the tubes using “Filshie clips”. Alternatively, the fallopian types can be tied and cut, or removed altogether. This can be done as an elective procedure, or during a caesarean section.
This prevents the ovum travelling from the ovary to the uterus along the fallopian tube
149
When do you need to use alternative contraception after female sterilisation procedure?
It’s required until the next menstrual period as an ovum may have already reaches the uterus during that cycle
150
What is gillick competence?
This refers to a judgement about whether the understanding and intelligence of the child is sufficient to consent to treatment. Gillick competence needs to be assessed on a decision by decision basis, checking whether the child understands the implications of the treatment.
Consent needs to be given voluntarily. When prescribing contraception to children under 16 years, it is essential to assess for coercion or pressure which may raise safegaurding concerns.
151
What are the Fraser guidelines?
Specific guidelines for providing contraception to patients under the age of 16 without parental input and consent
all the following requirements should be fulfilled:
the young person understands the professional's advice
the young person cannot be persuaded to inform their parents
the young person is likely to begin, or to continue having, sexual intercourse with or without contraceptive treatment
unless the young person receives contraceptive treatment, their physical or mental health, or both, are likely to suffer
the young person's best interests require them to receive contraceptive advice or treatment with or without parental consent
152
Intercourse in a child under 13 years old?
All intercourse in children under 13 years should be escalated as a safeguarding concern to a senior or designated child protection doctor.
153
What is FSRH?
Faculty of Sexual and Reproductive Healthcare
154
what % of couples globally use contraception?
64%
155
Globally what is the most popular method of contraception?
Female sterilisation
156
Average age of IUS user?
38
157
In which women might the newer IUS e.g. Jaydess or Kyleena be beneficial?
If they are having hormonal SE with the mirena
