Abstract
The Academy of Medicine (AMS) and Ministry of Health (MOH) have developed the clinical practice
guidelines on Assessment and Management of Infertility at Primary Healthcare Level to provide doctors and patients
in Singapore with evidence-based treatment for infertility. This article reproduces the introduction and executive
summary (with recommendations from the guidelines) from the AMS-MOH clinical practice guidelines on Assessment
and Management of Infertility at Primary Healthcare Level, for the information of SMJ readers. Chapters and page
numbers mentioned in the reproduced extract refer to the full text of the guidelines, which are available from the Ministry
of Health website: http://www.moh.gov.sg/content/moh_web/healthprofessionalsportal/doctors/guidelines/cpg_
medical/2013/cpgmed_infertility.html. The recommendations should be used with reference to the full text of the
guidelines. Following this article are multiple choice questions based on the full text of the guidelines.

Sexual intercourse every 2–3 days is recommended to
optimise the chance of pregnancy; this is less stressful
than timing intercourse to coincide with ovulation, which
is not recommended unless in circumstances preventing
regular intercourse (pg 22).
Grade D, Level 4
Women trying to get pregnant should be advised against
excessive alcohol consumption of more than two drinks
a day and episodes of binge drinking can cause fetal harm
(pg 23).
Grade B, Level 2++
Men should be warned that excessive alcohol intake is
detrimental to semen quality (pg 23).
Grade C, Level 2+
Women should be informed that smoking is likely to
reduce their fertility (pg 23).
Grade B, Level 1+
Men who smoke should be informed that smoking is
associated with reduced sperm parameters (pg 24).
Grade D, Level 4
Women trying to achieve a pregnancy should be informed
that a body mass index (BMI) of 19–29 kg/m
2 is optimal
(pg 24).
Grade B, Level 1+
Couples seeking treatment for infertility should be
routinely screened for usage of long-term prescription
medication, as some have been known to affect fertility
(pg 25).
Grade B, Level 2++
Couples seeking treatment for infertility should also be
routinely screened for occupational hazards and given
appropriate advice (pg 25).
Grade C, Level 2+
Women intending to become pregnant should be
informed that dietary supplementation with folic acid
before conception and up to 12 weeks’ gestation reduces
the risk of having a baby with neural tube defects. The
recommended dose is 0.4 mg per day. For women who
have previously had an infant with a neural tube defect or
who are receiving anti-epileptic medication, a higher dose
of 5 mg per day is recommended (pg 25).
Grade A, Level 1++
Women who are concerned about their fertility should
be offered rubella susceptibility screening so that those
who are susceptible to rubella can be offered rubella
vaccination and be advised not to become pregnant for at
least one month following vaccination (pg 26).
GPP
To avoid delay in fertility treatment, a specific enquiry about
the timing and result of the most recent cervical smear
test should be made to women who are concerned about
their fertility. Cervical screening should be offered
in accordance with the national cervical screening
programme guidance (pg 26).
GPP
Assessment and basic investigations of infertility
(including referral)
Couples with fertility concerns should be interviewed
separately as well as together, to bring out important
history that a partner may want confidential from the
other (pg 27).
Grade D, Level 4
At the initial consult, each couple should be assessed for
factors that may optimise or contraindicate the planned
pregnancy, possible underlying causes of infertility, and the
impact of infertility on the individual and relationship
(pg 27).
Grade D, Level 4
A detailed history-taking and clinical examination should
be carried out for couples with fertility concerns (refer to
Annex A for details) (pg 27).
Grade D, Level 4
Patients meeting these criteria should be referred to
specialists:
• Women aged 30 years who are unable to conceive
after regular unprotected intercourse for one year
without any known reproductive pathology.
• Patients with a known history of reproductive pathology,
e.g. amenorrhoea, pelvic inflammatory diseases,
endometriosis.
• Patients with a known history or reason for infertility.
• The presence of male problems e.g. history of urogenital
surgery varicocele, significant systemic illness (pg 27).
Grade D, Level 4
Semen analysis should be conducted as part of initial
investigation and should be compared to the following

• Volume (mL): 1.5 or more
• pH: > 7 .2
• Sperm concentration: 15 million spermatozoa per mL
or more
• Total sperm number: 39 million spermatozoa per
ejaculate or more
• Motility (PR + NP%): 40% or more motile*
• Vitality (%): 58
• White blood cells (106 per mL): < 1.0
• Morphology (%): 4 or more
*PR: progressive motility (WHO 1999, grades a + b);
NP: non-progressive motility (WHO 1999, grade c) (pg 28).
Grade B, Level 2+
If the first sperm analysis result is abnormal, the patient
should be offered a repeat test from the same laboratory at
least three months after the initial analysis (pg 28).
Grade B, Level 2++
Severe abnormality (azoospermia or severe
oligozoospermia) of the initial sperm sample, however,
warrants an immediate referral to a tertiary centre (see
section on male infertility) (pg 28).
GPP
Sperm function tests, screening for antisperm antibodies
and postcoital tests on cervical mucus should not be
offered, as there is no evidence of effective treatment to
improve fertility (pg 28).
Grade D, Level 4
Women with fertility concerns should have their menstrual
history taken (pg 29).
Grade D, Level 4
Use of basal body temperature charts and home
ovulation kits alone to predict ovulation should not be
recommended to patients with fertility problems, as these
are not always reliable in predicting ovulation, and
lead to unnecessary anxiety and stress for the patient
(pg 29).
Grade D, Level 4
Women with infertility should be offered a blood test
to measure mid-luteal serum progesterone levels (about
seven days before the expected menstrual cycle). If
cycles are irregular or prolonged, this test may need to be
repeated again weekly thereafter until the next menstrual
period (pg 29).
Grade B, Level 2++
Follicle-stimulating hormone (FSH) and luteinising
hormone (LH) investigations should be done on day 2–3
of the menstrual cycle. Patients with high levels of
gonadotrophins should be informed that they are likely to
have reduced fertility (pg 29).
Grade B, Level 2+
Women with infertility should be offered screening for
Chlamydia trachomatis before undergoing instrumentation
(pg 29).
Grade B, Level 2++
If screening for Chlamydia trachomatis has not been
carried out, prophylactic antibiotics should be given
before uterine instrumentation (pg 29).
Grade B, Level 2++
The result of semen analysis and assessment of ovulation
should be completed before the clinician embarks on
tubal assessment (pg 30).
GPP
Hysterosalpingography (HSG) should be used as the first-
line investigation in tubal assessment (pg 30).
Grade B, Level 2++
Chlamydia antibody titre (CAT) should be considered
as an alternative to HSG if the resources are available
(pg 30).
Grade A, Level 1+
Laparoscopy and dye hydrotubation should be offered to
women with comorbidities, such as pelvic inflammatory
disease, previous ectopic pregnancy or endometriosis
(pg 31).
Grade B, Level 2+
Fertiloscopy and transvaginal hydrolaparoscopy should
not be offered routinely as an alternative to laparoscopy
hydrotubation, as their diagnostic accuracy still requires
further evaluation (pg 31).
Grade C, Level 3
When available, transvaginal ultrasound may be used
as a screening test for the assessment of uterine cavity in
subfertile women (pg 32).
Grade C, Level 2+
Operative hysteroscopy should not be offered as an initial
investigation (pg 32).
Grade B, Level 2++

indicated. However, the achievement of a healthy weight
and modification of lifestyle should be tried first (pg 34).
Grade C, Level 2+
Where amenorrhoea (which occurs in women with
functional hypothalamic pituitary failure) has occurred
for longer than a year in duration, assessment of the bone
mineral densities should be considered (pg 34).
Grade C, Level 2+
When drug-induced anovulation is suspected, medications
should be altered or discontinued, if possible. If the
medication which causes anovulation cannot be altered or
discontinued, referral to a reproductive medicine specialist
for further management is indicated (pg 35).
GPP
Patients with anorexia nervosa should be referred to a
mental health care provider for further management (pg 35).
GPP
Patients with organic lesions of the hypothalamus and
pituitary gland should be referred to a reproductive
specialist (pg 35).
GPP
Women should be told that premature ovarian failure is
not a definitive diagnosis of infertility, as approximately
5%–10% of these women may conceive spontaneously
and unexpectedly after the diagnosis (pg 36).
Grade C Level 2+
Women with spontaneous premature ovarian failure
should be referred to an endocrinologist to investigate
asymptomatic autoimmune adrenal insufficiency (pg 36).
Grade C, Level 3
Fertility options in women with premature ovarian failure
include the use of an oocyte (egg) donor or embryo donor
in an Assisted Reproductive Programme (ARP) (pg 36).
Grade C, Level 2+
Dopamine receptor agonists are the first-line treatment for
patients with idiopathic hyperprolactinaemia secondary to
pituitary adenoma (pg 36).
Grade A, Level 1+
Surgical transsphenoidal resection of microadenomas
should not be the primary therapeutic approach for patients
with hyperprolactinaemia secondary to pituitary adenoma
(pg 37).
Grade C, Level 2+
Managing infertility in polycystic ovary syndrome
(PCOS)
Diagnosis of polycystic ovary syndrome should only
be made when other aetiologies have been excluded
(thyroid dysfunction, congenital adrenal hyperplasia,
hyperprolactinaemia, androgen secreting tumours and
Cushing’s syndrome) (pg 38).
Grade D, Level 4
The following investigations should be done to exclude
other aetiologies before a diagnosis of polycystic ovary
syndrome is made:
• Baseline laboratory screen:
– Thyroid function test (thyroid dysfunction can present
as amenorrhoea)
– Serum prolactin (hyperprolactinaemia can present as
amenorrhoea)
– 17 hydroxyprogesterone (only in the presence of
clinical or biochemical evidence of hyperandrogenism;
congenital adrenal hyperplasia can present as
amenorrhoea and hyperandrogenism)
– Free Androgen Index (FAI = total testosterone divided
by sex hormone binding globulin × 100 to give a
calculated free testosterone level) or free/bioavailable
testosterone (hyperandrogenism as one of the criteria
needed to diagnose polycystic ovary syndrome)
• Diagnostic imaging:
Pelvic ultrasound scan to determine features in accordance
with the Rotterdam criteria as well as to exclude
androgen secreting tumours of the adrenals or ovaries
(pg 39-40).
Grade D, Level 4
The following are optional tests in the diagnosis of polycystic
ovary syndrome:
• Gonadotrophin may be required to determine cause of
amenorrhoea (primary ovarian failure)
• Fasting insulin is not routinely necessary, but may be
considered in those undergoing ovulation induction
• ACTH stimulation test needs to be considered if
morning 17 hydroxyprogesterone > 5 nmol/L in order
to exclude non-classical congenital adrenal hyperplasia
(pg 40).
Grade D, Level 4
Before any intervention is initiated for women with
polycystic ovary syndrome, preconceptional counselling
should be provided, emphasising the importance of life-
style, especially weight reduction and exercise in over-
weight women, smoking and alcohol consumption
(pg 41).

The recommended first-line treatment for ovulation
induction remains antiestrogen clomiphene citrate (pg 41).
Grade A, Level 1+
Patients with polycystic ovary syndrome should be
informed that there is an increased risk of multiple
pregnancy with ovulation induction using clomiphene
citrate (pg 41).
Grade A, Level 1+
Ultrasound monitoring of follicular development at least
during the first cycle of treatment with clomiphene is
advisable to ensure that the women receive a dose that
minimises the risk of multiple pregnancy (pg 41).
GPP
Recommended second-line intervention for infertility
in women with polycystic ovary syndrome is either
exogenous gonadotrophins or laparoscopic ovarian surgery
(pg 42).
Grade D, Level 4
The use of exogenous gonadotrophins is associated with
increased chances of multiple pregnancy, and therefore,
intense monitoring of ovarian response is required
(pg 42).
GPP
Laparoscopic ovarian surgery alone is usually effective
in < 50% of women, and additional ovulation induction
medication is required under those circumstances (pg 42).
Grade B, Level 2++
Low-dose therapy with gonadotrophin is recommended, as
it offers a significantly lower risk of ovarian hyperstimulation
in women with polycystic ovary syndrome (pg 42).
Grade B, Level 2++
The recommended third-line treatment for infertility
in women with polycystic ovary syndrome is in vitro
fertilisation (pg 42).
Grade C, Level 2+
As aromatase inhibitors are currently not licensed for use
as ovulation induction, we do not recommend the clinical
use of aromatase inhibitors for routine ovulation induction
(pg 43).
GPP
The routine use of metformin in ovulation induction is not
recommended as monotherapy or in combination with
clomiphene citrate (pg 43).
Grade D, Level 3
There is currently insufficient evidence to suggest
improvement in live birth rates on treatment with met-
formin before or during assisted reproductive technique
cycles, and its routine use is not recommended (pg 43).
Grade B, Level 2+
The combined use of metformin and clomiphene citrate
is recommended for women with clomiphene resistance,
especially if they are obese (BMI > 27 .5 kg/m
2) (pg 44).
Grade A, Level 1+
There is insufficient evidence to recommend the
widespread use of metformin in pregnant women with
polycystic ovary syndrome (pg 45).
GPP
Young women diagnosed with polycystic ovary syndrome
should be informed of the possible long-term risks to
health that are associated with their condition (pg 45).
GPP
Patients presenting with polycystic ovary syndrome,
particularly if they are obese, have a strong family history
of type 2 diabetes, or are over the age of 40, should be
offered a glucose tolerance test (pg 45).
Grade B, Level 1+
Women diagnosed with polycystic ovary syndrome should
be asked (or their partners asked) about snoring and
daytime fatigue/somnolence, and be informed of the
possible risk of sleep apnoea, and offered investigation
and treatment, when necessary (pg 46).
Grade B, Level 2++
Clinicians should continue to identify cardiovascular risk
factors (including blood pressure, cholesterol, triglycerides
and high density lipoprotein cholesterol) in women with
polycystic ovary syndrome and treat these accordingly
(pg 46).
Grade B, Level 2++
Women diagnosed with polycystic ovary syndrome
should be advised regarding weight loss through diet and
exercise (pg 47).
Grade A, Level 1+
Combining metformin and lifestyle modification, including
calorie restriction and exercise to facilitate weight loss and
attenuate central adiposity, is recommended for obese
patients with polycystic ovary syndrome. Higher doses
of metformin, up to 2.5 g/day, may be recommended to
achieve an optimal response (pg 47).

D Ovarian electrocautery should only be reserved for slim
women with anovulatory polycystic ovary syndrome
(pg 48).
Grade D, Level 3
Women who have been diagnosed as having polycystic
ovary syndrome before pregnancy, especially those
requiring ovulation induction for conception, should be
screened for gestational diabetes before 20 weeks of
gestation, with referral to a specialist obstetric diabetic
service if abnormalities are detected (pg 49).
Grade B, Level 1+
Male infertility
Both male and female partners should be investigated
concurrently for couples who present for infertility
assessment (pg 50).
GPP
Semen analysis should be done as the primary investigation
for male infertility (see section 4) (pg 50).
Grade B, Level 2+
Hormonal investigations for male infertility should be
limited to FSH, LH and testosterone levels (pg 50).
GPP
Karyotyping and Y microdeletion test should be considered
for men with nonobstructive azoospermia (pg 51).
Grade D, Level 3
Referral to a tertiary centre should be made for:
• Patients with azoospermia
• Patients with severe semen abnormality
• Patients with clinical evidence of varicocele
• Patients with erectile dysfunction
• Patients with anejaculation
• Patients with retrograde ejaculation
• Patients with suspected androgen deficiency
• Couples who will benefit from assisted reproductive
technologies (pg 51).
GPP
General advice, such as cessation of smoking, steroid use
and withdrawal of offensive medication could be given at
primary setting (pg 51).
GPP
Couples trying to conceive should generally avoid
exposure to harmful chemicals (e.g. by wearing protective
clothing when appropriate to reduce the risk of exposure to
harmful chemicals) (pg 51).
GPP
Antioxidant supplementation for subfertile males may be
used to improve live birth and pregnancy rates for subfertile
couples (pg 52).
Grade A, Level 1+
Referral to a fertility specialist should be facilitated if the
female is over 35 years old (pg 52).
GPP
Varicocele treatment may be considered when the
female evaluation is normal and the man has a palpable
varicocele with suboptimal semen quality (pg 52).
Grade B, Level 2++
In azoospermia, spermatozoa may be retrieved from
the testis/epididymis using a variety of techniques such
as testicular sperm aspiration (TESA), testicular sperm
extraction (TESE), microsurgical epididymal sperm
aspiration (MESA) and percutaneous epididymal sperm
aspiration (PESA). Sperm cryopreservation should be
offered at the time of sperm retrieval (pg 53).
GPP
When retrograde ejaculation is suspected, post-ejaculatory
urinalysis (looking for presence of sperm and fructose)
may be requested (pg 53).
GPP
It is important to exclude retrograde ejaculation and aneja-
culation from other causes of azoospermia, as drug therapy
may be used to allow spontaneous conception (pg 53).
Grade C, Level 3
When available, penile electrovibration and transrectal
electroejaculation should be considered before embarking
on surgical sperm retrieval and intracytoplasmic sperm
injection (pg 54).
Grade D, Level 4
Delayed ejaculation and anorgasmia may have biogenic or
psychogenic aetiology. After exclusion of medical illnesses,
referral could be made to a sexual therapist who could
help in education, counselling and instruction in revised
sexual technique to maximise sexual arousal (pg 54).
GPP
Management of premature ejaculation depends on the
underlying aetiology, patient’s needs and preference. For
lifelong premature ejaculation, selective serotonin reuptake
inhibitors (SSRIs) are preferred, while for secondary
premature ejaculation, behavioural techniques are the
preferred option (pg 54).

Patient with premature ejaculation should be informed
that daily SSRI is more effective than on-demand SSRI
treatment. On-demand use of topical anaesthetics and
tramadol may prolong intravaginal ejaculatory latency
(pg 54).
Grade B, Level 2++
Phosphodiesterase type 5 (PDE 5) inhibitors should not
be prescribed to men with premature ejaculation when
there is no associated erectile dysfunction (pg 54).
Grade B, Level 2++
All patients presenting with erectile dysfunction should
have their history taken and assessment done to identify
cardiovascular risk factors such as hypertension,
hyperdyslipidaemia and diabetes, as these are commonly
associated with cardiovascular disease (pg 55).
GPP
Although referral to a fertility clinician can help with
fertility issues by doing in vitro fertisilisation/intra-
cytoplasmic sperm injection, multidisciplinary referral
should be considered in the following situations:
• Complex endocrine disorder (to endocrinologist)
• History of pelvic or perineal trauma, penile deformities or
penile implants (to urologist)
• Psychosocial issues or relationship problems (to
counsellor, psychologist, psychiatrist) (pg 55).
GPP
First-line treatment for erectile dysfunction should
include patient counselling and education, risk factor
modification (smoking cessation, reduce alcohol, improved
diet and exercise, weight loss) and addressing psycho-
social issues (relationship difficulties, anxiety) (pg 55).
Grade D, Level 4
Oral agents (PDE 5 inhibitors) such as tadalafil (Cialis),
sildenafil (Viagra), vardenafil (Levitra) have similar
efficacy, tolerability and safety for the treatment of erectile
dysfunction. Choice of drug should be individualised
based on patient needs (pg 55).
Grade A, Level 1+
Phosphodiesterase type 5 (PDE 5) inhibitors should
not be taken with nitrate-containing medications for
erectile dysfunction, as the concurrent use of nitrate
medications and PDE 5 inhibitors is contraindicated.
Patients need to be educated that they require
sexual stimulation for these medications to work
(pg 56).
Grade D, Level 4
Vacuum devices and rings are suitable for men with
erectile dysfunction who have contraindications for
pharmacologic therapies. It should only be prescribed by
clinicians who are familiar with its use (pg 56).
Grade C, Level 2+
Men with erectile dysfunction who are resistant to
PDE 5 inhibitors should be referred to a urologist as
combination therapy (PDE 5 inhibitor plus vacuum erectile
device, intraurethral medication, intracavernosal injection,
androgen supplement, α -blocker) or invasive treatment
such as penile implant may be considered (pg 56).
Grade C, Level 2+
Hormone assays should be performed to test for
androgen deficiency. As there is diurnal rhythm in hormone
secretion, blood samples for testosterone should be
taken in the morning (pg 56).
Grade D, Level 4
The result of hormone assays should be interpreted
with caution, as there is no appropriate standardised
Reference
range for all laboratories. Therefore, clinical
assessment (recent changes in sexual function, patterns
of body hair and secondary sexual characteristics) is
important to diagnose androgen deficiency (pg 56).
GPP
When fertility is desired, testosterone should not be
used to treat androgen deficiency. When the causes are
secondary to hypothalamus or pituitary disorders, human
chorionic gonadatropin (HCG) injection may be used
instead (pg 57).
Grade B, Level 2++
Tubal-infertility (preventive strategies & treatment)
Women with high risk profiles (early sexual debut, multiple
partners, noncompliance with safe sexual advice, etc.)
should be screened for Chlamydia trachomatis in their
urogenital tracts and be promptly treated to prevent future
repercussions, including tubal infertility (pg 58).
Grade C, Level 2+
Partners of Chlamydia-positive women should be tested
and treated to prevent reinfection of the treated women.
Positive cases should be referred to the Department of STI
Control for contact tracing and treatment (pg 58).
Grade C, Level 2+
Oral doxycycline (100 mg twice daily for 7–14 days) and
azithromycin (1 g stat dose) are recommended antibiotics
against Chlamydia trachomatis (pg 58).

High-risk women who are scheduled for invasive
instrumentation of the reproductive tract should be
empirically treated for Chlamydia to prevent ascending
infection of the upper reproductive tract, or reactivation of
past infection (pg 59).
Grade B, Level 2++
Assessment of tubal patency should be considered
in all infertile women (pg 59).
GPP
Women with low risk for tubal disease (based on the history
and physical examination), should be screened with a HSG
for tubal patency as part of assessment for infertility (pg 59).
Grade B, Level 2++
Endometriosis
A detailed vaginal examination with bimanual palpation
and/or rectal examination is essential to detect nodular
lesion on the uterosacral ligaments, rectovaginal septum
or other surfaces accessible digitally. The detection rate of
physical examination is better during menstruation (pg 60).
Grade C, Level 2+
Magnetic resonance imaging may be considered as an
adjunctive investigation tool to laparoscopy in the diagnosis
of deeply infiltrating endometriosis (pg 61).
Grade C, Level 2+
Serum CA125 should not be used in the routine
investigation of endometriosis due to inadequate specificity
and sensitivity (pg 61).
Grade B, Level 2++
Diagnosis of endometriosis should be made at
laparoscopy unless disease is visible in the vagina or
elsewhere (pg 61).
Grade D, Level 4
Diagnostic laparoscopy for endometriosis should not
be undertaken within 3 months of ovarian suppressive
treatment, as there is a high risk of missing the lesions and
leading to a false negative result (pg 62).
