Fertility Facts Four common topics that may come up in your office (and why IVF is not just a money grab) Dr. Carol Redmond Hannam Fertility Centre, Toronto November 2014
The Questions • “Can you check my fertility?” • “Can I freeze my eggs?” • “I’m not getting pregnant, can I just take Clomid?” • “If Clomid doesn’t work, what does help? How does IVF work?”
“Can you check my fertility?” • History • AGE • Regular cycles • History of STI • Family history of early menopause • Symptoms of endometriosis http://whattoexpectwhenyouarenot.wordpress.com/
Ultrasound Endometrioma Submucosal Fibroid PCO occur in 1/3 of women without PCOS http://www.fornewyou.com/Endometrioma-Cyst http://www.medscape.com/viewarticle/491677_2 http://tatjana-mihaela.hubpages.com/hub/polycysticOS
Age • Egg quality declines with age • Egg quality is the gate keeper to fertility • If all else is normal, egg quality decides cycle fecundity and success rates with ART http://nymag.com/news/features/mothers-over-50-2011-10/
Myths and Misconceptions • “My cycles are regular so my fertility is fine” • “I’ve stayed fit and healthy so my fertility has been maintained” • “My day 3 FSH is good so my fertility is still fine” • “All the women in my family get pregnant easily over age 40” • “I got pregnant easily the first time so I will be fine”
Age • Daniluk surveyed 1021 women age 20-40 (2010) • Most expected to have more than 1 child in their 3rd or 4th decade • 70% expected to start after age 30 • 60% wanted 2 children • 20% wanted more than 2 children • Most thought health was a better predictor of fertility than age
Age • The first sign of aging of the eggs is infertility • There are no other clinical or biochemical signs • The first clinical sign of aging is a shortening of the cycle (Lambalk, 2009)
Odds of Natural Conception Age of marriage and percentage of women not using contraception but childless (Menken, 1986) Estimated age-related chances of conception within 12 months resulting in live birth (Leridon, 2004) Age Age
Age • So if eggs are the gate keeper, can we assess egg quality? NO!
Age • Egg quality can only be assessed at the time of IVF • What is “ovarian reserve testing” testing then? • This is testing egg quantity • Egg quantity declines with age • If number of eggs is declining, it is a reasonable assumption that another aging process – declining egg quality – is also ongoing
Tests of Ovarian Reserve • AMH • AFC (AntralFollicle Count) • Day 3 FSH
Tests of Ovarian Reserve • AMH • Produced by pre-antral and small antral follicles • The serum level reflects the number of small follicles in the ovaries • The absolute level does not predict fertility • The ideal range is 15-30 pmol/L
Does Low AMH Level Matter? • 1/3 of young women (age 21) will have an AMH level <12 pmol/L (Lund Kristensen, 2012) • 26% of potential egg donors showed an AMH level in the low range (Gleicher, 2010) • I surveyed 94 women presenting to HFC for donor sperm
How Do We Use AMH Levels? • Changes in AMH may matter • A dropping AMH level suggests declining egg numbers, which indicates ovarian aging, which suggests egg aging • AMH predicts ovarian responsiveness • AMH is a good predictor of the ability of the ovary to “superovulate”
Tests of Ovarian Reserve • Antral follicle count • Also measures the reserve of small follicles, but very observer dependent • FSH • This is the last thing to change as the ovary ages • Significant decline in ovarian reserve can occur in the presence of a normal FSH level • High FSH level strongly predicts an inability of the ovary to “superovulate”
“How can I tell if I’m fertile?” • Try to get pregnant • A low AMH level at any age does not preclude pregnancy • A normal AMH level does not imply normal fertility http://pregnancytips.org/getting-pregnant/how-to-get-pregnant/trying-to-get-pregnant/
“Can I freeze my eggs to be safe?” • Egg freezing is now a reliable technology with the advent of egg vitrification • Most of the babies are from frozen donor eggs • A survey in 2012 of the 7 USA Commercial Egg Banks revealed that 8780 frozen eggs had generated 602 pregnancies (6.8%) (Quaas, 2013) http://retrievefreezerelax.com/egg-freezing-basics/
Egg Freezing • We can expect a thaw rate of 86% • And a fertilization rate of 76% • So 10 eggs on average will generate 3 blastocysts • Implantation rate per embryo from fresh eggs: • SART data, 2012, (n=165,172 cycles)
Egg Freezing • The success rate will depend on the quality of the eggs being frozen • This will decline with age • Chang,2013
Egg Freezing • This is where AMH levels fit in • The AMH level is a reasonable predictor of egg yield with IVF • A 37 year old with an AMH of 7? • Maybe 3 eggs to freeze, which may make 1 embryo, if all three eggs thaw and fertilize, with IR of 27%
Egg Freezing • Things to consider: • Effort – requires ovarian stimulation and egg retrieval • Very little data yet on thawing and pregnancy rates (CCRM has had 47 thaws of non donor frozen eggs in the past few years (personal communication, 2014) http://www.bodyconfidential.co.uk/Health/Egg-Freezing-A-21st-Century-Dilemma
Egg Freezing • Things to consider (cont): • Cost!
Embryo Banking • This is a more certain option • Proceed with IVF, fertilize eggs, make embryos, screen embryos with PGS for aneuploidy • Each euploid embryo has a 60-70% chance of a live birth – independent of age at transfer http://www.biopoliticaltimes.org/article.php?id=5833
“I’m not getting pregnant, can’t I just take Clomid?” The Miracle Drug Clomid • First get a diagnosis • Ovulation • Semen analysis • Sonohysterogram to check uterus and tubal patency http://www.kinetic-international.net/Oral_clomid50.html
Myths and Misconceptions • “We didn’t havesex on exactly the right day” • “I know it’s because I’ve been stressed” • “The sperm leaks out” • “I need to lie there for ½ hour” • “We are having sex too often/not often enough” • “It doesn’t matter that we smoke – all our friends do and they have kids” http://raspberrytruffles.org/trying-is-fun/
Clomid • Estrogen receptor blocker • Can induce the development of more than 1 egg per month (40% of cycles) • 40% of women have anti-estrogenic side effects (thin endometrium, poor cervical mucus) which impede pregnancy • Nuisance side effects: headaches, visual flashes, hot flushes, moodiness
Clomid • How well does it work? • Not very… Clinical Pregnancy Rate Per Cycle
What Does Work? Hannam Fertility Center, 2014
What Does Work? Age IUI Cycle # Hannam Fertility Center, 2014
FSH Superovulation and IUI • FSH • Daily injections for 10-13 days • Daily monitoring with blood & USS • Costly • 20% of pregnancies are twins • 1% are triplets
IVF • Two multi-centre prospective randomized trials in a population of patients with unexplained infertility and unsuccessful Clomid and IUI looked at proceeding to FSH and IUI then IVF as needed, or straight to IVF • Both showed a higher pregnancy rate achieved in fewer cycles and at a lower cost if the patients proceeded directly to IVF • (FORT-T trial, 2014, & FASTT trial, 2010)
IVF • 272 women COH & IUI • CLBR after 2 cycles 27% • Twins 13% • 1 triplets • 1 quadruplet • 176 women IVF • LBR after 1 cycle 39% • Twins 10% • (Chambers, 2010) http://www.co-parentmatch.com/In-Vitro-Fertilization-IVF.aspx
IVF Hannam Fertility Center, 2014
IVF • National Health Service funded IVF • < 40 years of age, 3 IVF cycles • Took less than 2 years to achieve 3 cycles (Goswami, 2013)
IVF with PGS • PGS = pre-implantation genetic screening for aneuploidy • Euploidy rate • 56% if excellent blastocyst morphology • 39% if good blastocyst morphology • 42% if average blastocyst morphology • 25% if poorblastocyst morphology • (Capalbo, 2014)
IVF & PGS Case Studies • 39-40 year old woman with unexplained infertility • Over 4 IVF cycles she generated • 33 year old woman with unexplained infertility • Over 1 IVF cycle she generation
IVF & PGS Case Studies • 40 year old trying for 2 years
IVF & PGS • Recurrent implantation failure • (Greco, 2014)
IVF & PGS & Miscarriage • PGS is the answer to most miscarriage (Benner, 2012)
IVF & PGS & Miscarriage Case Study • 40 year old TDI X 8 • IVF
IVF • Women for donor sperm over age 40 • Nearly all successful IVF was in first attempt • Single IVF = 6 cycles of TDI • (De Brucker, 2013)
Summary • Age remains the best predictor of fertility • AMH levels do not predict fertility • Serial AMH levels may have value • Egg freezing is great technology (when applied to young women) • If you are sub-fertile, there is no simple approach that also has a great success rate • IVF, particularly with PGS, if highly effective, but not simple or natural
