40
What treatment should women with Group II ovulation disorders be offered?
Dopamine agonists e.g. bromocriptine
41
How has the prevalence of tubal microsurgery changed as a method of managing infertility?
Decreased with the introduction of IVF
42
When is tubal microsurgery still used?
- Salpingectomy or tubal clipping prior to IVR in presence of hydrosalpynx - Preliminary ovarian cystectomy or myomectomy - Salpingolysis to release peritubal adhesions - Salpingostomy - blocked tubal end held open
43
What risk increases following all forms of tubal surgery?
Risk of ectopic pregnancy
44
What is a myomectomy?
Operation to remove fibroids
45
What anaesthesia is used in a myomectomy?
GA
46
When can a myomectomy help to manage infertility?
When very large fibroids are making it difficult to become pregnant or fibroids must be removed for assisted conception
47
What are the risks of myomectomy?
- GA risk - Bleeding - Need for hysterectomy - Damage to surrounding structures
48
Why may a hysterectomy be needed following a myomectomy?
When very heavy bleeding cannot be stopped and life is at risk
49
What are the potential complications of a myomectomy?
- Infection - DVT and PE - Pain - Recurrence
50
What is assisted conception?
Procedures whereby treated or manipulated sperm are brought into proximity with oocytes
51
What are some examples of assisted conception?
- Intrauterine insemination (IUI) with partner or donor sperm - IVF - Intracytoplasmic sperm injection
52
What is IUI?
Introduction of prepared sperm into the uterine cavity around the time of ovulation
53
How does ovulation occur in preparation for IUI?
Can be stimulated with gonadotrophins or unstimulated
54
Who should unstimulated IUI be considered in?
- Unable to conceive vaginally due to disability or psychosexual problems - Where consideration of method of conception is required e.g. male HIV - People in same sex relationships
55
What is the physical requirement for IUI?
Healthy, patent fallopian tubes
56
What are the live birth rates for IUI in good quality centres?
15-20%
57
How does IUI compare to IVF in terms of cost effectiveness?
More cost effective
58
Why is IUI more cost effective than IVF?
- Lower doses of gonadotrophins - Reduced monitoring - Simplified laboratory requirements
59
What % of IVF treatments result in a live birth?
25%
60
What reduces the chance of IVF success?
Age of woman
61
How many cycles of IV should women under 40 be offered?
3
62
What should happen to IVF if a woman reaches 40 during treatment?
Current cycle should be completed then treatment withdrawn
63
How many cycles of IVF are offered to women over 40?
1 as long as they meet criteria
64
What criteria must women over 40 meet to be offered IVF?
- Never had past IVF - No evidence of of low ovarian reserve - Discussed implications of IVF and pregnancy at advanced age
65
How are eggs obtained in IVF?
Stimulation of multiple ovarian follicles using gonadotrophins and GnRH agonists/antagonists
66
Why are GnRH agonists/antagonists used in IVF?
To prevent premature LH surge and ovulation
67
How are oocytes collected for IVF?
Transvaginal ultrasound guided needle follicle aspiration with oocytes isolated from fluid
68
How are oocytes fertilised in IVF?
Cultured with a washed sample of sperm
69
How long are oocytes cultured for?
5 days to reach the blastocyst stage of division
70
Why are oocytes left to reach blastocyst form?
So a detailed assessment of morphological quality can be made
71
What is the most common obstetric problem associated with IVF?
Premature birth due to multiple pregnancy
72
How many embryos are transferred in IVF?
Recommendation is of one top-quality blastocyst when available
73
Why is transfer of one blastocyst recommended?
To reduce the risk of multiple pregnancy
74
What happens to the remaining blastocysts in IVF?
Cryopreserved for use later if conception fails
75
When may oocyte donation be appropriate?
- Premature ovarian failure - Gonadal dysgenesis e.g. Turner syndrome - Bilateral oophrectomy - Ovarian failure following chemo or radiotherapy - Some cases of IVF failure - Where there is risk of transmitting genetic disorder
76
When is it unlikely therapy will help with male infertility?
- Small testes - Azoospermia - High FSH - Low AMH
77
What is the most likely cause of male infertility if testes and FSH is normal?
Ductal obstruction
78
What test should be performed if ductal obstruction is the suspected cause of male infertility?
Testicular biopsy
79
What testicular biopsy result indicates likely ductal obstruction?
Normal spermatogenesis
80
What is the treatment for ductal obstruction causing male infertility?
Vasography and scrotal exploration followed by surgical anastamosis
81
What can help treat male infertility due to hypogonadotropic hypogonadism?
Gonadotrophins
82
What can be given to help improve fertility of men with hyperprolactinaemia?
Dopamine agonists
83
What are some unproven but widely practiced treatments for male infertility?
- Varicocele ligation | - Supplements
84
What is the most successful treatment for male infertility?
Intracytoplasmic Sperm Injection (ICSI)
85
What happens in ICSI?
A single immobilised sperm is injected into the oocyte cytoplasm
86
How do the pregnancy rates of ICSI compare to IVF?
Similar
87
What is the main concern with ICSI?
There is a slightly higher rate of abnormality in children conceived after ICSI
88
What are the main abnormalities seen in children following ICSI?
- Genital tract abnormalities e.g. hypospadias, testicular maldescent - Imprinting disorders e.g. Angelman and Beckwith-Widemann syndromes
89
When is sperm donor insemination used?
If sperm cannot be obtained from the partner for ICSI or the partner is a carrier for a genetic disorder
90
What should be given to both parties of sperm donor insemination?
Independent counselling
91
Is sperm donation anonymous?
No
92
What has happened as a result of sperm donation being made non-anonymous?
Decrease in donation
