1 Fertility issues for patients with lymphoma
Cheryl Fitzgerald Dept of Reproductive Medicine St Mary’s Hospital Manchester

2 Issues to consider Two diagnoses Delay in conception
Malignancy and infertility Counselling Delay in conception Marked decline in female fertility 35 onwards Effect of disease/treatment Spermatogenesis Ovary – oocytes Uterus – radiotherapy induced damage

3 Issues affecting fertility
Delay in conception – female Disease Surgery Chemotherapy Radiotherapy Long term prognosis – Welfare of Child

4 Male Options - easy Female Options complex

5 Men Men and postpubertal boys Need to screen for Hep B, Hep C and HIV
Urgent direct referral Phone Andrology SMH – Produce single (?more) sample Frozen in several ampoules Stored for up to 55 years Sperm used for insemination or IVF

6 Options for treatment with cryopreserved sperm
Sperm quality good – use for insemination Sperm quality poor – use for IVF Treatment within NHS dependent upon NHS assisted conception guidelines Sperm can be transferred to private sector is not eligible

7 Delay in conception - females
Initial treatment Long term therapy (breast) Time until “cure” Age related decline in female fecundity Age related decline in ovarian reserve Increase in oocyte aneuploidy Marked reduction 35 onwards

8 Effects of chemotherapy
Damage to primordial follicles Damage to primary follicles Oogenesis – many months May be temporary disruption No benefit from GnRH agonist treatment No effect on uterus

9 Risk factors for iatrogenic POF
Older women – poor ovarian reserve Dose, type and duration of chemotherapy Pelvic radiotherapy / TBI

10 Effects of radiotherapy
Site specific Pelvic radiotherapy / TBI profound oocyte damage profound uterine damage Oocyte damage Premature ovarian failure Uterine damage Poor implantation rates after XRT Poor pregnancy outcome after XRT

11 Fertility preservation options – pre-treatment
Cryoprserve ovarian tissue Cryopreserve oocytes Cryopreserve embryos Consider uterine function

12 Ovarian cryopreservation
Laparoscopic oophorectomy Ovarian cortex frozen in strips Later – replace ovarian tissue within pelvis Spontaneous/stimulated ovarian cycle ?? In vitro maturation in the future 10 (+2) babies worldwide No time limit on storage

13 Ovarian storage Risks Very low success rates Risk of laparoscopy
Risk of re-introducing disease Benefits No need for hyperstimulation No raised oestradiol level No need for partner Minimal delay in treatment

14 Who is suitable? Lymphoma patients Very young girls ?? Prepubertal
No metastatic disease in ovaries Limited time

15 Primordial follicle grafting
Stored ovarian tissue Primordial follicles grafted into mice No need to transplant tissue Ref. Brison et al Not published

16 Egg and embryo freezing
Need to retrieve mature eggs from ovaries No stimulation – single egg – poor success Need for ovarian hyperstimulation

17 Ovarian hyperstimulation cycle
10 days of ovarian stimulation – starts with period NB – delay caused by waiting for menses Vaginal egg recovery Ostradiol raised through stimulation

18 Oocyte cryopreservation
problematic chromosomes on spindle aneuploidy after thaw zona pellucida and cortical granule damage affect fertilisation need for ICSI

19 Oocyte cryopreservation
Freeze all mature eggs recovered Can be stored for 55 years HFEA Code of Practice 8 No reduction in “quality” of eggs with increasing time

20 Oocyte cryopreservation - progress
Improving ++ vitrification Rapid cooling without crystal formation Vitrification Slow freeze Survival 80% 60% Fertilisation 75% 65% Pregnancy 9% 4%

21 Safety of egg freezing 936 babies Birth anomalies – 1.3%
No difference compared to spontaneously conceived children Noyes et al 2009

22 Embryo cryopreservation
need a partner “urgent” IVF minimum time 4-6 weeks ovarian hyperstimulation oocyte recovery eggs inseminated embryos created frozen

23 Risks associated with “urgent” IVF for egg or embryo cryopreservation
high circulating oestradiol ( cf 500 pmol/l) issue with Ca breast potential seeding of gynae malignancies delay in cancer treatment

24 Egg and embryo cryopreservation
Risks High circulating oestradiol Delay to treatment Need for partner (embryos) Risk that partner will “change mind” (embryos) Benefits Successful Proven method Proven safety

25 Chance of baby – embryo freeze
HFEA data – livebirth per fresh cycle 2008 <35 years 32.8% 35-37 years 27.3% 38-39 years 19.0% 40-42 years 11.8% 43-44 years 4.8% >44 years 3.8% 30% embryo loss with freezing

26 Embryo freezing Freeze all embryos created at pronucleate stage
Can be stored for 55 years No reduction in “quality” of embryos with increased time in storage

27 Practicalities Urgency – referral early
Fax referral and confirm by phone Cycle control – COCP – limits delay Details Timing of chemo Need for pelvic radiotherapy Longterm therapies Prognosis

28 After treatment Referred as any infertility patient

29 Egg donation Donor – IVF stimulation Partner sperm for insemination
Embryo(s) replaced in recipient HRT support to 12 weeks of pregnancy Success rates – 30-50% Right of child to access donor information

30 Surrogacy After hysterectomy / pelvic radiotherapy Problematic +++
No legal contract Surrogate – legal mother

31 Eligibility – IVF in NHS
NHS IVF guidelines Female < 40 years Stable cohabitation >2 years One partner childless Only couples treated Female BMI< 30 No previous sterilisation

32 Fertility preservation eligibility - NHS
Female age ? Cohabitation - ? One partner childless Single women treated BMI ? No previous sterilisation NB – PCT funding – needs agreement

33 Welfare of the Child Legal requirement HFEA Act
Prognosis for patient important Partner / family support

34 Thank-you
