Course coordinators Egbert te Velde (The Netherlands) and Lone Schmidt (Denmark) Course description In this course we aim to go beyond the usual margins of our discipline and catch your attention for the paramount importance of prevention of infertility. In dealing with patients, in our social surroundings but also in our teaching responsibilities prevention of infertility is important, may be more so than you have realized so far. In fact preventive measures can already start before conception, may be even before the time people realize they wish to have children. But preventive thinking might also be important for couples who intend to have children much later in life e.g. around women’s menopause. In between those periods, raising fertility awareness in young people, measures to prevent STDs and giving advice to women and men how to combine a stressful, heavy or responsible job with the wish to have children, are some of the topics to be covered. Much attention is focused on the impact of postponing parenthood on fertility. Can we do something to prevent this, can we predict which women and men rather should not postpone but also: can society play a role and do something about it? Attending this course might change the routine of your daily practice Target audience Reproductive physicians, paramedical personnel and all those who are interested in the epidemiological, social and ethical aspects of our work.

WHAT IS INFERTILITY AND WHAT IS PREVENTION
OF INFERTILITY?
An introduction to the course on “Prevention of infertility- from preconception to post-menopause”
Dik Habbema, Chair of Medical Decision Sciences, ErasmusMC University Medical Center
Rotterdam, the Netherlands
To be presented at ESHRE 2011, Stockholm
Preliminary version, March 2011
Learning objectives and reference
 Learning objectives:
 *to know and recognize the different meanings of “infertility” and their
interrelationships
 *to have an overview of the possibilities for prevention of infertility as
discussed in the course
 Ref:Human reproduction 2004 Vol 19 1497-1501 (Towards less
confusing terminology in reproductive medicine: a proposal)
INFERTILITY IS A MULTIFACETED CONCEPT
 Infertility has many connotations:
 Infertility as used in common language and in medicine
 Infertility as a biological condition prohibiting procreation
 Infertility as a descriptive term for not having produced children
 Infertility as a prognostic term expressing poor chances of pregnancy
 Infertility as a medical care term, as a condition for intervention
Page 17 of 131
Infertility, common language
 Oxford English Dictionary: 1. Unable to reproduce 2. Unable to sustain
crops or vegetation (of land)
 Cobuild English Language Dictionary: infertile 2. a person or animal
that is infertile is unable to have or to produce babies....infertility is
often considered a synonym of sterility
Infertility, medical language
Dorland Medical Dictionary(25th edition). Infertility: sterility;absence of
the ability to conceive, or to induce conception
INFERTILITY, causal meaning
 “The couple can not have children because they are using contraceptives”
 “The couple is infertile, because the man has no sperm”
 “The couple is infertile, because the woman has two-sided tubal blockage
 “The couple is infertile, because the woman is already 45 years old”
The examples thus far give absolute causes. Now a few relative ones:
“The woman is already 38 years of age”
“The man has a reduced sperm quality”
Relative causes can be used as an explanation of not getting pregnant, and
have probabilistic prognostic value.
Page 18 of 131
INFERTILITY, descriptive
 “ The fertility in this country has decreased over the last decades”
(demographical use)
 “The couple had no child during the last three years”
 “ The couple has unsuccesfully tried to get children for three years”
 ANALYSIS: all sentences are descriptive. The last sentence refers to
actively trying to get pregnant, the first one not.
 Descriptive term with duration indication: “x-year infertility”
INFERTILITY, prognostic
 Qualitative prognosis :”the couple has a good/moderate/poor
possibility of becoming pregnant without treatment.”
 Quantitative prognosis : ”the couple has a x% chance of becoming
pregnantt within
ithi y years.””
 Thus, prognostically, infertile means a poor chance (e.g. under 20%)
of getting pregnant during the coming year.
Infertility in medical care
 In medical care, “Infertility” justifies medical action, according to
guidelines.
 Examples:
 *After 1-year infertility (descriptive), a diagnostic fertility investigation is
recommended.
 *After 3-year infertility with unknown cause, IVF is indicated.
Page 19 of 131
Infertility and reduced (prognostic) fertility
 Reduced fertility because of relative factors
 *Age (ovarian aging)
 *Duration of trying to get pregnant(adverse selection)
 *Diagnostic findings( poor semen, adhesions )
Relationships between meanings of infertility
 Example 1 : 1-year infertility (descriptive)
 *is at odds with lay- and medical- language use of the term
 *does not imply prognostic infertility(chance in next year ~ 50%)
 *does not imply causal infertility
 *has medical care interpretation of recommendation of fertility investigation
 Example 2: 1-year infertility with subsequent finding of 2-sided tubal blockage (causal
infertility) implies the lay- and medical language interpretation, implies prognostic
infertility and has medical care implication of recommendation of immediate IVF
treatment.
 Example 3: 1-year infertility with subsequent finding “unknown cause”.
See example 1, but now with recommendation of trying to get pregnant without
treatment.
CONCLUSIONS ON MEANINGS OF INFERTILITY
 *Infertility has many meanings.
 *Try to be precise on your use of the term
 *Do not try to coin one exclusive definition for “infertility”. Do justice to
the multiple meanings by using correct qualifications.
 *Be aware that one meaning does not necessarily imply other
meanings. This applies strongly to “1-year infertility”.
Page 20 of 131
PREVENTION OF INFERTILITY
 There are many exciting and challenging possibilities for prevention of
infertility.They will be discussed during this course. Targets are:
 *Occupational fertility risks(Jens Peter Bonde)
 *Infertility risks from infectious diseases(Lone Schmidt)
 *Reproductive knowledge and fertility awareness( Jacky Boivin)
 *Policy measures for (early) family formation(Ronald Rindfuss)
 *Age at which family formation is started(Egbert te Velde)
 *Life-style before and during pregnancy(Robert Norman)
 *Accessible good quality fertility medicine(Allan Trounson)
 *Older age fertility “insurance” by cryopreservation(Sjoerd Repping)

Reasons to develop a fertility
awareness tool
A validated self-administered, multifactorial tool that would
enable women to get fertility guidance based on their
own lifestyle and reproductive profile did not yet exist
A tool would:
allow women to make informed decisions about current
lifestyle and reproductive behaviour,
 potentially help women take action to safeguard future
fertility where risk exists (e.g. quit smoking) and;
 motivate women to seek timelymedical advice (if
desired) when clear symptoms of disease (e.g. absence
of period) are, possibly unknowingly, undermining
current attempts to conceive.

that could be perceived as a conflict of
interest.
I hope you will learn, understand and accept that 1):
• The duration of the infertile period and female age are the most
important determinants of infertility
• There is a large difference between the prevalence of primary 1-year
infertility and of primary sterility
• Secondary infertility is a complex concept
• There has been an enormous postponement of first childbirths since
the 1970s: consequence of the availability of good contraception
and female emancipation.
• The mean age at first childbirth has risen with 4-5 years: mothers
are much older than in former days
Page 74 of 131
I hope you will learn, understand and accept that 2):
• Because of delay of motherhood we estimate that primary sterility
has increased from 2-3% to 5-7% in most Western countries.
• This is a large effect when taking into account it is the tip of the
iceberg of many more adverse consequences of delay
• With the present utilization ART has hardly a compensating effect on
the consequences of delay.
• Prevention of infertility due to delay is probably possible to a certain
degree
The contraceptive and sexual revolution liberated
women from their reproductive destiny (Van de Kaa 1987)
•
The unbreakable link between sex
and reproduction was broken
•
Women were liberated from the
unavoidable burden of
motherhood and male dominance
•
Women could decide to have
children or not, and how many
•
Freedom at last!
• Women could postpone
motherhood until later or
never, and they did!

Duration of the period of infertility and primary
infertility
• Primary infertility: not (yet) a child
• The prevalence of primary infertility very much depends on the
duration couples have tried to conceive: the longer the lower the
prevalence (Habbema et al
al.2004).
2004)
• On the population level of the Netherlands in1970:
- 1-year infertility = ~22%
- 2-year infertility = ~12%
- 3-year infertility = ~9%
- Lifelong infertility = primary sterility = ~3%
Defining secondary infertility: less simple than primary
infertility
•
The woman has at least one child and becomes infertile thereafter
•
May occur after the first child but also after the fifth or eighth
•
The prevalence of secondary infertility also depends on the duration
couples have tried to conceive: 1-year, 2-year, 3-year to lifelong secondary
infertility = secondary sterility. This may occur after a woman had one child
but also after 5 or 8 children
•
The impact of postponement on secondary infertility is difficult to assess: did
infertility start when trying to have a second, third or eighth child?
•
In Western countries the mean no. of children 1.3 – 2.0. We estimated that
the effect of postponement on the prevalence of primary sterility in the
population is about 1.5 larger than of secondary sterility (te Velde et al. submitted)

Time (months)
The proportion of couples who tried but failed to have children
because of the delay of their first child, must have increased: how
to estimate this increase?
•
We simulated the reproductive career of all women going for their first child
in 6 representative countries in 1970, 1985 and 2007 using the microsimulation model developed by Leridon (Leridon 1977 and Leridon 2004)
•
The model accounts for the age-dependent time to pregnancy and the loss
of fertility as a woman grows older
•
After one year off non-conception

Couples with severe causes of infertility get immediate IVF/ICSI treatment.
The remaining after another 2 years unless spontaneously pregnant in the
mean time
•
One IVF/ICSI treatment consists of 3 reimbursed IVF/ICSI cycles
•
Estimations of the effect of ART are based on the 2003-2004 results of all
IVF/ICSI cycles in NL (Lintsen et al. 2007). For the incorporation of the
effect of ART in the micro-simulation model see Habbema et al. 2009.

The countries to be selected: 1)had to be
representative of a region 2) the age distribution of the
mothers at first childbirth had to be available
• The Netherlands NL representative for Western Europe
• Sweden SE representative for Northern Europe
• Spain ES representative for Southern Europe
• West Germany W-Ger and Austria AT representative for Central
Europe
• The Czech Republic CZ representative for Eastern Europe
What did we want to find out?
1)
What is the effect of delay of first motherhood on sterility rates
during the last decades
2) To what extent can ART compensate for the rise in sterility by
delay?
As a consequence of delay of first childbirth sterility rates rose by ~
2.5% in SWE, ~ 3% in AUT, W-GER, CZE and NL, and ~ 4% in ESP
since 1985.

Increased sterility is the tip of the iceberg of associated
adverse effects caused by delay such as:
• More secondary infertility and sterility
• More pregnancy complications and premature births
• More children from twin/triplet pregnancies
• More children with genetic defects
• Increased risk of getting breast cancer (Collaborative Group on
Hormonal Factors in Breast Cancer 2001 )
To what extent can ART compensate for the rise in
sterility by delay?
• Scenario 1 = ART 100%: all couples eligible for ART will get the full
treatment of 3 IVF/ICSI cycles
However, only about one quarter will make use of IVF/ICSI and often
less than 3 cycles (Snick et al. 1997, Brandes et al. 2009, van Balen et al.
1997 Boivin et al
1997,
al. 2007
2007, Oddens et al
al. 1999
1999, Malcolm and Cummings 2004
2004,
Crosignani and Collins 2010)
• Scenario 2 = ART 25%: only one quarter of the couples eligible for
ART will make use of it
Does ART compensate the increasing sterility rates caused by
delay? ART 100% more or less does; the effect of ART 25% is
almost negligible.

Is prevention of postponement of first
childbirth possible?
Much attention of the popular press for the victories of
reproduction technology including the possibility of
old women to become mother
•
Young people grossly
overestimate the chances of
having a child by ART (Lampic et al.
2006; Guardian Fertility Poll 2006)
•
Young women overestimate the
natural chances of having a child
after 35 (Lampic et al. 2006,
Tough et al. 2007)
•
Many couples are unaware of the agerelated decline of fertility (Schmidt
2010)
Perceived max age until you can wait to have your first
child – EU women aged 25-39 (Mills et al. 2011)
Page 81 of 131
Prevention 1. Fertility awareness and education
• Information at a young age that fertility is declining with age,
especially of women
• ART can hardly compensate for this trend
Prevention 2. Policy measures to enhance the
possibility of combining a profession with having
children in time
• Lecture Ronald Rindfuss
Prevention 3. Counsel women at age 20-30. Determine
the lifespan until the onset of menopause. If short: do
not delay. If long: you can still wait

selected European countries

Why the increase in age at first
birth? Some broad reasons
• Educational attainment levels have
increased in all countries; in many
countries, female educational attainment is
higher than male’s
• Increase in female labor force
participation, especially “career” type jobs
• Extended period of post-adolescence
dependency
• And in some countries, a lack of
movement towards gender equity (in the
labor market and within the household).
Page 90 of 131
Demographically dense
• Traditionally 18-30 were the prime
childbearing years – starting to stretch to
35 (& moving towards 40)
• These young adult years are
demographically dense (leaving school,
obtaining employment, migrating,
marrying, divorcing, remarrying)
• Next figure is U.S. circa 1990, but I expect
the picture would be similar for all the
countries under consideration
To understand the next figure
• Shown are fertility, migration, marriage,
school leaving & unemployment rates,
ages 0 to 80
• Ages 18-30,
18 30 the young adult years
years, are
shown with a thicker dark line than the
other ages
• What you should see is that the young
adult years are demographically dense!

Basic Sociology – a review
• Institutions are the set of norms or rules,
formal and informal, which guide
relationships among role occupants in
areas of structured social interactions.
interactions
Institutions influence social relations
among people.
• Examples: housing market, labor market,..
Basic Sociology – a review,
cont.
• Policies are formal norms or rules within
institutions, and exist until formally
changed
• Policies can influence AAFB intentionally
or inadvertently. Inadvertent AAFB policies
have received little research attention.
• We’ll discuss intentional AAFB policies
first, and then inadvertent ones.
Do institutions matter?
• The next two slides show that the
relationship, at the country level, between
female labor force participation rates and
fertility changed from being negative to
positive between 1970 and 1990.
• Most argue that this change occurred
because of differing institutional responses
across countries to the universal rise in
female labor force participation.
Page 92 of 131
Do institutions matter, cont.
• What happened?
• My read: in some countries it was (or
became) easier to combine the worker and
mother roles; in other countries
countries, women
needed to choose between one or the
other.

Evaluating policy effectiveness: a high
degree of difficulty
• Experiments tend not to be used, for
ethical, political and practical reasons
• Country, rather than provincial, level
policies (Thus tends to be a constant
within a country and not visible if just
studying one country)
• Confluence of a country’s policies and its
culture & ideology, which is difficult to
disentangle
Policy evaluation, cont.
• A policy’s effect might only occur in the
long run
• Degrees of freedom problem, that is,
relatively few countries available for
statistical analysis
Policy evaluation, cont.
• Upshot:
• Need a healthy skepticism regarding
currently published evaluations
• A shaky
h k empirical
i i l ffoundation
d ti on which
hi h tto
provide advice to policy makers
• Considerable speculation exists in the
research literature
Page 94 of 131
Intentional AAFB or overall
fertility policies
1. Direct cash payments
• Examples: baby bonus, family allowances
• Evidence on success: at best, mixed.
• My read: most studies have been of
questionable quality, but it is unlikely that
direct cash payments will have a large
impact on AAFB
Intentional AAFB or overall
fertility policies, cont.
2. Indirect transfers
• Example: tax exemptions for families with
children, housing benefits for families with
children or health benefits
• Note: Sometimes these are inadvertent
policies
• Evidence: Modest or no effects
• My read: Unlikely to have a big impact on
AAFB
Intentional AAFB or overall
fertility policies, cont.
3. Improve work-family compatibility
• Background: Sociologists talk about role
incompatibility; economists talk about
opportunity costs
costs. Both getting at a similar
issue: Today’s jobs (and school) are
incompatible with taking care of a child,
especially a very young child. Workplaces
have changed. Parenting demands have
changed.
Page 95 of 131
Intentional AAFB or overall
fertility policies, cont.
• Examples: maternity & paternity leave with
or without salary maintenance, provision of
child care
• Evidence: In general
general, lowering the
incompatibility between the mother and
worker roles leads to a younger AAFB.
(Very long maternity leaves seem to be an
exception.)
Intentional AAFB or overall
fertility policies, cont.
• My read: The evidence is strongest that
high quality child care that is available,
acceptable, accessible and open during
normal working & commuting times
decreases AAFB.
Page 96 of 131
Policies with inadvertent effects
on AAFB
• Here we are speculating. There has been
relatively little empirical work confirming
these effects. Housing policies have
received the most attention
attention.
1. Housing. General hypothesis is that
anything that makes it easier for young
adults to obtain their own dwelling unit will
lead to younger AAFB.
Policies with inadvertent effects
on AAFB, cont.
• Background: countries differ markedly on
the percent of down payment needed to
obtain a mortgage, price of housing, size
of rental market,
market availability of credit
reports, and the ease of foreclose.
• Example: in Italy, large down payments
(40-50%) are required, credit histories are
not widely available, and foreclosures
cannot be enforced until 48 months after
mortgage payments have ceased.
Policies with inadvertent effects
on AAFB, cont.
• Evidence: Relatively weak, but
consistently showing a positive association
between ease of obtaining a dwelling unit
and TFR
TFR.
• My take: the hypothesis is intuitively
plausible and likely true.
Page 97 of 131
Policies with inadvertent effects
on AAFB, cont.
2. Educational systems: a) are primary
school hours compatible with balancing
work and family responsibilities. If not,
AAFB is likely to be later.
later b) Is it feasible to
return to school after having dropped out?
If not, AAFB likely to be later.
• Evidence: not much
• My take: both are likely true
Policies with inadvertent effects
on AAFB, cont.
• 3. Job market: Institutional factors that
lead to high youth unemployment likely
lead to later AAFB.
• Evidence: extremely limited
limited, but
supportive of the hypothesis.
• My take: the hypothesis is intuitively
plausible and likely true.
Policies with inadvertent effects
on AAFB, cont.
4. Work re-entry: is it relatively easy for a
mother to have her old job or obtain a new
one after having stopped working to care
for a young child.
child
• Note: this goes beyond maternity leave
issues to include hiring practices of
employers. For example in Japan,
employers like to hire individuals who have
just finished school.
• Evidence: none
Page 98 of 131
A quick summary
• Policies that ease the conflict between
mother and worker roles seem to lower
AAFB, especially those that make child
care more available
• Direct and/or indirect transfers seem to, at
best, have modest effects
• Policies with inadvertent effects on AAFB
theoretically are likely to influence AAFB,
but the empirical evidence is not yet
available.

• Think about the difference between Oslo’s
subway system and Tokyo’s

LCIVF Foundation Mission:
To reduce the burden of childlessness for couples in underdeveloped and low resource societies. The Foundation is establishing Low Cost IVF Clinics at several sites in low resource countries and ensures that local clinicians and scientists who are identified as key personnel receive adequate training.
The Foundation also nominates one or more observers for each site to provide expert advice ensure that established protocols are followed and monitor success rates for
advice, ensure that established protocols are followed, and monitor success rates for the simplified procedures.
An education program for awareness of reproductive health forms an integral part of the established Low Cost IVF Clinics. This program is aimed at improving couples’ knowledge about reproductive processes, infectious diseases, and safe sex practices.
The Low Cost IVF Foundation is committed to maintaining administrative costs to a minimum and all clinical expertise is provided pro bono.

Outline
• Men
– What causes infertility?
– Which infertility can be prevented?
– How can infertility be prevented?
• Women
– What causes infertility?
– Which infertility can be prevented?
– How can infertility be prevented?
• Discussion
Male infertility
• Impaired semen quality
– Below WHO values for normal spermatogenesis
– 5th percentile of a cohort of healthy men
WHO guidelines, (2010)
Page 113 of 131
Male infertility
• Correlation between semen quality and chance of
pregnancy
Van der Steeg, et al., F&S (2010)
Causes of male infertility
• Causative factors
–
–
–
–
–
Hyperprolactinemia
Hypogonadotrophic hypogonadism
Bilateral cryptorchidism
Orchitis
Genetic causes
• Numerical and structural chromosome abnormalities
• Y-chromosome deletions
– Previous chemochemo- or radiotherapy

Fertility preservation
• Cryopreservation of semen
– Masturbation
– Electroejaculation
• Cryopreservation of spermatozoa
– Surgical retrieval
• MESA (epididymis)
• TESE (testis)
• Before start of chemotherapy
Sperm banking in the AMC

(21--3-2011)
–
968 patients
ti t
– 2.627 ejaculates
– 36.199 straws
Use of cryopreserved semen
• First documented use in 1953
• Treatment option depends on quality
– 15% can be used for cervical insemination
– 10% requires intrauterine insemination (IUI)
• Mild ovarian stimulation
• 15% ongoing pregnancy per cycle
– 75% requires in vitro fertilization (IVF) w/ or w/o ICSI
• Ovarian hyperstimulation
• Invasive / burdensome
• 25% ongoing pregnancy per cycle
Bunge & Sherman, Nature (1953), Repping (unpublished data)

Clinical problem
• Sperm cryopreservation not possible in children
• Increased success in pediatric oncology
– ~80% survives childhood cancer
– 1:250 young adults is childhood cancer survivor

Human prepubertal testis
• Two boys with NonNon-Hodgkin (6.5 and 8 years of age)
Sadri Ardekani, et al., JAMA (2011)
Future developments
• Elimination of cancer cells
– Do they survive weeks of culture?
• Safety
– (Epi)genetic stability
– Health of offspring (mouse model)
• Adapt culture for clinical use
– Use of clinical grade products
– GMPGMP-setting
• Transplantation technique in human testis
Page 118 of 131
Alternatives
• Tissue transplantation
– Autologous / xenografting
• In vitro spermatogenesis
• Both require ART
Van Saen, et al., HR (2011), Sato, et al., Nature (2011)
Causes of female infertility
• Tubal occlusion
• Endometriosis
• Anovulation
• Imminent ovarian failure

Oocyte freezing
• Widely applied
–
–
–
–
Rapid introduction
Standard procedure
> 900 children born
Vitrification most applied method
Kuwayama, et al., RBMO (2005) Theriogenology (2007)
Ovarium cortex transplantation
• Freezing ovarian cortex
– Can be done rapidly
• (Auto)transplanting ovarian cortex
– Limited experience
– Possible risk of reintroducing malignant cells
– Case series monozygotic twins
• Discordant for ovarian failure
Woodruff, et al., Nat Med (2009), Smitz, et al., HRU (2010),
Silber, et al. NEJM (2005) (2007) HR (2008)
Page 120 of 131
In vitro folliculogenesis
• Freezing ovarian cortex
• Freezing GV oocytes
• In vitro folliculogenesis
– Prevent reintroduction malignant cells
– Preclinical breakthroughs
– No human pregnancies
Woodruff, et al., Nat Med (2009), Schmitz, et al., HRU (2010)
Gonadotoxic treatment

Time / age
Social versus Medical
• Difference in acceptance
• But difficult to separate
• Phase I (freezing) has different indications
– Cancer treatment / age
• Phase II (thawing) same indication
– Infertility
• Dutch view
– Both social and medical situation are indications
– Dutch embryology / gynecology society September 2010
– Accepted by Dutch parliament April 2011
Discussion
• Fertility can be preserved in
– Men / women
– Prepubertal / adult
– Established / experimental
• Fertility preservation should be discussed whenever
infertility is on the verge of occurring
– Oncologists
– Family doctor
– Society
