Preparation for IVF



 Of the patients

 Of staff and facilities

 Of organisation

• Review of U.K. infertility Guideline

algorithm (2004, but valid)

• Emphasis on process leading to IVF

U.K. National

Guideline developed

by a multidisciplinary

group:

Stages

TIFF (Un compressed) decompressor

are neede d to see this picture.

1. Process published

2. Draft formulated

3. Professional

consultation

with interested

bodies

4.Modification

5. Final publication

Background

• The Guideline was produced for the NHS because of the wide

variation in and limited access to NHS treatment. It covered a new

review of the research evidence.

• The National Institute for Clinical Excellence (NICE) Guideline was “to offer

best practice advice on the care of people in the reproductive age

group who perceive that they have problems in conceiving” (Feb.2004)

• Based on the Management of Infertility (RCOG,1998-2000) :

initial (primary) investigation and management,

management in secondary care and

management in tertiary care.



The full Guideline (CG11, 500pp. with refs) “Fertility assessment and

treatment for people with fertility problems” is available (as a 1.21Mb

file) at:

http://www.nice.org.uk/guidance/index.jsp?action=download&o=29269

Grades of Evidence

LEVEL EVIDENCE GRADE

1a Systematic review and meta-analysis of RCTs A

1b At least 1 (randomised controlled trial) RCT

At least one well-designed CT without

2a B

randomisation

At least one other type of quasi-experimental

2b

study

Well-designed non-experimental descriptive

3 studies, such as comparative, correlation or C

case-control studies

Evidence from expert committee reports or

4 opinions &/or clinical experience of respected D

authorities

The view of the Guideline Development Group GPP

Algorithm for assessment and treatment

for people with fertility problems (NICE)

• Definition of infertility - 2 years

• Initial advice to people concerned about conception

• Early investigation

- history of predisposing factors

- woman’s age ≥ 35y

- HIV status

- hepatitis B & C

• People preparing for cancer treatment (oocyte cryopreservation)

• Principles of care

- Couple centred management

- Access to evidence-based information (verbal and written)

- Counselling from someone not directly involved in management

of the couple’s infertility

- Contact with fertility support groups

- Specialist teams

Initial advice -1

 Cumulative probability of pregnancy in

the general population

 Fertility declines with a woman’s age

• Lifestyle advice

 Preconceptual advice

-folic acid, rubella, cervical screening

Initial Advice - 2

• Intercourse at least every 2-3 days C

• Alcohol not >2-3U/day (F) D

not >3-4 U/day (M) GPP

excess alcohol is detrimental to semen quality B

• Smoking may reduce fertility in females, refer to cessation

programme A

• Smoking in males: no link, but stopping will improve

general health GPP

• Passive smoking may reduce fertility B

• No consistent evidence about caffeinated beverages (tea,

coffee, cola) B

• BMI ≥30 (F), if anovulatory, lose weight, preferably in a

group A

• BMI ≥30 (M) is likely to be associated with reduced fertility C

• BMI 2 transferred in any one cycle

- Offer cryostorage if >2 embryos

- Frozen embryos to be transferred before further

stimulated cycle

- Ultrasound guided embryo transfer on

day 2 or 3, or day 5 or 6

• Luteal support

- progesterone

Management options with IVF

or other forms of ART - 1

• ICSI

- Severe semen defects, azoospermia

- Poor IVF treatment response

- Screen by karyotype

• Donor insemination

- Azoospermia

- Genetic disease in male partner

- Severe rhesus isoimmunisation

- Severe semen defects

For female:

- Confirm ovulation, HSG if no pregnancy after 3 cycles

Management options with IVF or

other forms of ART - 2

• Oocyte donation

- Premature ovarian failure

- Gonadal dysgenesis including Turner syndrome

- Bilateral oophorectomy

- Ovarian failure following chemo- or radio-therapy

- Some cases of IVF treatment failure

- Gene disorder transmission to offspring

- Screen donors

- Risks of ovarian stimulation and egg collection

• Egg sharing - counselling

Key priorities in infertility management (3/6)

before IVF

Assessing tubal occlusion

and uterine abnormalities

• Screen for Chlamydia before uterine instrumentation B

(A key priority)

• If positive, treat and refer the sexual partner for screening C

• Consider prophylactic antibiotics before uterine

instrumentation if not screened GPP

• If no co-morbidities (pelvic inflammatory disease, previous ectopic,

endometriosis) offer HSG (hysterosalpingogram [or hysterosalpingo-

contrast-sonography] A) to screen for tubal occlusion B (A key

priority)

• If co-morbidities, offer laparoscopy B

• Hysteroscopy should be clinically indicated and not used routinely.

Treatment of uterine anomalies is not clearly linked to fertility B

• Do not use routine post-coital testing of cervical mucus as it has no

predictive value for pregnancy rate A

Intrauterine insemination



• Mild male factor, unexplained infertility and

mild to moderate endometriosis should

have 6 cycles of IUI A (A key priority)

• It should be unstimulated IUI in male factor

and unexplained infertility A

• Use stimulated IUI for mild to moderate

endometriosis A

• Use single insemination (A) and Fallopian

tube perfusion A

Summary

And so on… through secondary and tertiary care; also providing auditable standards

for the Clinic, the Andrology lab and the Assisted Reproduction clinic







Secondary Care Tertiary Care

• Initial investigations • Location of Services

• Pelvic assessment • Organisational and

management responsibility

• Patient choice of management

• Quality management

• Support services • Resource management

• Ovulation induction • Assisted conception services

• Unexplained infertility • Gamete donation

• Endometriosis • Evaluation and improvement

• Continuing professional

development

CONCLUSION

• A great deal of preparation is required

before IVF can be implemented:

- agreed protocols

- informed staff

- patients prepared factually and

emotionally

- Efficient, responsible organisation
