Human Reproduction
Monthly probability of conception = fecundability
Monthly probability of live birth = fecundity
Average human monthly fecundity = 20%
Getting pregnant is usually a matter of chance

Some Facts about Ageing, Men and Sperm
• As men age the testes get smaller and softer, sperm morphology and motility tend to decline
• DNA fragmentation increases
• IVF pregnancy rate decreases as DNA fragmentation increases
• Paternal age >50 leads to doubling the chance of fetal death
• Paternal age >40 leads to increased rate of miscarriage independent of maternal age

Some Facts about Older Men and Sperm
Paternal age is a robust risk factor for the incidence of:
schizophrenia in offspring
• at 45+ odds ratio 3.0 = 1: 46 chance
(Malaspina 2001)
increase in autism
• specific for schizophrenia
• compared with 30 years
• > 40 3 x the risk

Ovarian reserve
• Predicting earlier/faster egg loss:
- Follicle stimulating hormone (FSH) levels
- Antral follicle scans (‘Egg check’)
- Anti-Mullerian Hormone (AMH) levels
- Poor response to ovarian stimulation in IVF
• Predicting later/slower egg loss:
- No test known
• Nothing can improving the quality of eggs or delay the loss of eggs

Public Funded Fertility Treatment
• Fertility assessment
• Primary (GP, nurse practitioner)
• Secondary (Hospital)
• Tertiary
– DHB contracted providers (Fertility Associates, OFS)
– Specialist first assessment is covered if the criteria are
met
– Two treatment “cycles” (IVF, DI x4, Donor eggs = 1
cycle)

Eligibility for Public Funding
• Eligibility is determined by CPAC (Clinical Priority Access Criteria) specifically defined for fertility services throughout New Zealand.
• Couples require a CPAC score of more than 65 to access treatment.
• The scoring is complex and includes some factors which make patients ineligible for Public Funding: – Women who smoke are required to stop and be smoke free for
three months to become eligible
– Women with a BMI greater than 32 or less than 18 are required to lose or gain weight
– Women aged 40 or older are excluded
– Patients with two children in their current relationship or two children from previous relationships aged 12 or younger living at home

Eligibility for Public Funding • Severe causes of infertility (anovulation, bilateral tubal damage,
poor sperm) score a higher CPAC score.
• Previous vasectomy or tubal ligation, duration of infertility and history of unsuccessful other treatments are taken into account.
• Lesbian couples and single women may be eligible for Public Funded treatment if they have a biological reason for fertility delay or have not achieved pregnancy after 12 cycles of donor insemination.
• Funding covers the most appropriate treatment for that patient and may include ovulation induction, insemination of sperm, donor insemination, IVF, egg donation or surrogacy.

• Wilcox 1988:
30 % pre-clinical loss
• Luteal phase – doubles over 16 hrs
• from 4w to 7w (ELISA) – doubles over ~48 hrs

Early pregnancy ultrasound
• Mean Gestational Sac diameter
– If >20mm with no Yolk Sac , no embryo = EPL
• Crown Rump Length
– If > 6mm without fetal cardiac activity = EPL
– But if CRL <6mm , repeat in 7 days
• Expect CRL increase ~ 1mm/day and +FH
• Heterotopic pregnancy (1% IVF…1/3000)

Pregnancy of unknown location • (PUL) ? 8-31% of presentations
• = + HCG with no sign of intra or extra uterine
pregnancy with no evidence retained POC
• 4 possible reasons
– Failing pregnancy
– Early viable pregnancy
– Early ectopic
– Persistant PUL

Discriminatory zone • Correlation of HCG with GSD (but note centiles)
• Limitations: – Twin gestation (higher than expected HCG)
– USS hardware (TV USS 1000-1500iu cf Abdo USS 5000iu)
– USS operator experience
• HCG doubling over 48 hrs in ongoing pregnancy – cf Complete EPL HCG should fall to <20% in 48hrs
– cf after ERPOC HCG should fall by ~15% in first 12 hrs
• ?serum progesterone – <15 nmol implies non-viable pregnancy
– >80 nmol 97% sensitivity to exclude ectopic
– BUT many patients between 15 to 80 nmol
![Page 121: Infertility: ‘from whoa to go’ South/Thurs_Greenslade_1630_Phillipso… · • Severe causes of infertility (anovulation, bilateral tubal damage, poor sperm) score a higher CPAC](https://reader036.vdocument.in/reader036/viewer/2022071002/5fbee18197ee2a1de900ba96/html5/thumbnails/121.jpg)
Ectopic Pregnancy:
? Expectant management • If stable + no haemato peritoneum or signs of
tubal rupture
• HCG <200iu (?<1000iu)
• ??60% resolve.
• Careful followup USS and HCG
![Page 122: Infertility: ‘from whoa to go’ South/Thurs_Greenslade_1630_Phillipso… · • Severe causes of infertility (anovulation, bilateral tubal damage, poor sperm) score a higher CPAC](https://reader036.vdocument.in/reader036/viewer/2022071002/5fbee18197ee2a1de900ba96/html5/thumbnails/122.jpg)
Ectopic Pregnancy:
? Medical management • If stable + no haemato peritoneum
• HCG <5000 iu
• EP diameter <30mm
• No fetal cardiac activity
• No contraindication to Methotrexate – (Viable pregnancy, liver, renal , bone abnm.)
• Follow up USS and HCG. ?80% resolve
• But 10% persist or rupture even if HCG falls – ( possible even if HCG falls to non-pregnant
levels)

Summary
• Understanding of physiology
• Correlation of history, dates, HCG and USS
• Careful follow-up @ 48 hours
• HCG doubling expected 4-7weeks
– if plateau or failure to fall after presumed
intrauterine loss / ERPOC ?ectopic
• Limitations of single HCG, P, USS <6/40
