Infertility is a common condition with
important psychologic, economic,
demographic, and medical
Infertility is a unique medical condition
because it involves a couple, rather
than a single individual.
It is defined as inability of a couple to
conceive after 12 months of regular
intercourse without use of contraception in
women less than 35 years of age; and
after six months in women 35 years
Some clinicians use the term subfertility
to describe this failure to conceive unless
the couple has been proven to be sterile.
5. Primary infertility
is the term used to describe
a couple that has never
been able to conceive ,after
at least 1 year of
7. NORMAL FERTILITY
A study examined the number of months to
conception in 5574 normal women who had
unprotected intercourse and who became
pregnant . Eighty-five percent of the women
conceived within 12 months.
Five to 15 percent of apparently normal couples
will conceive in the second 12 months of
attempted conception so that after 24 months ,
95 percent of couples will have conceived.
11. The World Health Organization (WHO) task
force on Diagnosis and Treatment of Infertility
performed a study of 8500 infertile couples and
utilized standard diagnostic criteria to determine
the medical conditions contributing to infertility.

Tubal disease and pelvic adhesions
prevent normal transport of the oocyte and
sperm through the fallopian tube.
Previous surgery or non-tubal infection
(eg, appendicitis, inflammatory bowel
Women with distal tubal obstruction may
develop hydrosalpinges, which decrease
the success rate of (IVF). In addition to
obstruction to sperm migration,
hydrosalpinges appear to reduce fertility
retrograde flow of tubal contents into the
endometrial cavity, which creates a hostile
environment to implantation of an embryo.

2.Deficient to support the developing embryo
3.Toxic to the developing embryo
28. Classification of Tubal disease
British Fertility Society
Proximal occlusion without tubal fibrosis
Distal occlusion without tubal distension
Healthy mucosal appearance at HSG,
Flimsy peritubal/ovarian adhesions.
Unilateral severe tubal damage
Limited dense adhesions of tubes & ovaries
Bilateral severe tubal damage
Extensive tubal fibrosis
Tubal distension >1.5 cm
Abnormal mucosal appearance
Extensive dense adhesion
Impaired implantation, either mechanical or due
to reduced endometrial receptivity, are the basis
of uterine causes of infertility
Uterine leiomyomata:A meta-analysis showed
that only leiomyomata with a submucosal or
intracavitary component were associated with
lower pregnancy and implantation rates.
The likely mechanism is inhibition to normal
31. Uterine anomalies; Uterine abnormalities are
thought to cause infertility by interfering with
normal implantation. Müllerian anomalies are a
significant cause of (RPL), with the septate
uterus associated with the poorest reproductive
Other structural abnormalities associated with
infertility include endometrial polyps, and
synechiae from prior pregnancyrelated
Mechanisms which decrease fertility in women
with endometriosis include
Anatomic distortion from pelvic adhesions,
damage to ovarian tissue by endometrioma
formation and surgical resection,
and the production of substances such as
cytokines and growth factors which impair the
normal processes of ovulation, fertilization, and
33. 4-CERVICAL FACTORS
Normal midcycle cervical mucus
facilitates the transport of sperm.
Congenital malformations and trauma
to the cervix (including surgery) may
result in stenosis and inability of the
cervix to produce normal mucus,
thereby impairing fertility.
Unexplained infertility is the
diagnosis given to couples after a
thorough evaluation has not revealed
Many cases of unexplained infertility
may be due to small contributions
from multiple factors.
35. When To start Workup
An infertility evaluation is usually initiated after
one year of regular unprotected intercourse in
women under age 35 years and after six months
of unprotected intercourse in women age 35
years and older.
However, the evaluation may be initiated sooner
in women with
irregular menstrual cycles or endometriosis,
a history of PID,
or reproductive tract malformations.
Both couples should be present
Previous pregnancies by each partner
Duration of infertility
Frequency and timing of intercourse
Use of lubricants
42. Very long list of tests, have been
advocated to assist in
determining the cause of the
infertility in the diagnostic
evaluation of infertile couple.
The necessity and cost effectiveness
of performing many of these tests and
correcting the abnormalities found by
them have not been demonstrated.
43. 1-Investigations of Male Factor
Conventional semen analysis
Computer- assisted sperm analysis (CASA)
A variety of sperm function tests
- The acrosome reaction test
- Hypo-osmotic swelling test
- Measurement of generation of Reactive oxygen species
- Sperm capacitation assays
- Hemizona-binding assay
- Hamster penetration test
- Human sperm-zona penetration assay
A variety of imaging techniques for detection of
44. Semen Analysis
Semen analysis is the key laboratory
assessment of the male partner of an infertile
The standard semen analysis consists of the
Semen volume and pH
● Microscopy for
• Sperm concentration, count, motility, and
morphology • Debris and agglutination
• Leukocyte count• Immature germ cells
45. Semen Analysis
The semen sample should be collected
after two to seven days ejaculatory
If possible, the patient should collect the
sample by masturbation at the doctor's
office. If not possible, then the sample may
collected at home and delivered to the
laboratory within an hour of collection.
48. 2-Assessment of ovulation
Basal body temperature
Urine LH kits
Mid luteal serum progesterone
Routine hormonal profile: FSH, LH, Prolactin,TSH
Serial pelvic Ultrasonography.
A variety of tests for assessment of ovarian reserve
such as D3 FSH & E2, Inhibin B, Clomid challenge test,
TVS for ovarian volume, antral follicle count and
Stromal blood flow.
49. Evidence of ovulation:
1. Menstrual history of regular cycles.
2. Serum progesterone in the mid-luteal
phase of their cycle (day 21 of a 28-day
cycle) even if they have regular menstrual
3. Serum gonadotrophins ( FSH & LH) on
Day2-3 especially in irregular periods.
(N.B.: No role for basal body temperature
50. Further investigations
-More important in >35 years old, suspected
ovarian failure and to detect response to
1. Total antral follicle count.
2. AMH of less than or equal to 5.4 pmol/l for a
low response and greater than or equal to 25.0
pmol/l for a high response
3. FSH greater than 8.9 IU/l for a low response
and less than 4 IU/l for a high response.
51. D 3 FSH
Both the day 3 FSH level and the CCCT,
which is a provocative test for
measurement of FSH, are widely used for
screening ovarian reserve.
The CCCT involves oral administration of
100 mg clomiphene citrate on cycle days 5
through 9 with measurement of day 3 and
day 10 FSH levels and day 3 estradiol
A value less than 10 mIU/mL suggestive of
adequate ovarian reserve.
52. Antral follicle count (AFC)
Ultrasound examination can be used to
determine the number of antral follicles (defined
as follicles measuring 2 to 10 mm in diameter).
On transvaginal ultrasound,
The ovaries are visualized in their transverse
and longitudinal planes and the antral follicles
are counted and measured; the size of the
follicle is the mean of two perpendicular
diameters, one of which should be the largest
dimension of each follicle
A low AFC ranging from <4 to 10 antral
follicles between days two and four of a
regular menstrual cycle suggests poor
Although AFC is a good predictor of
ovarian reserve and response,
It is less predictive of oocyte quality,the
ability to conceive with IVF, and pregnancy
55. Antimüllerian hormone (AMH)
is expressed by the small (<8 mm) preantral and
early antral follicles. The AMH level reflects the size
of the primordial follicle pool, and may be the best
biochemical marker of ovarian function across an
array of clinical situations.
The AMH level appears to be an early, reliable, direct
indicator of declining ovarian function.
AMH level correlates with the number of oocytes
retrieved after stimulation, and is the best biomarker
for predicting poor and excessive ovarian response.
Unlike the day 3 FSH, AMH can be
measured anytime during the menstrual
AMH <0.5 ng/mL predicts reduced ovarian
reserve with less than three follicles in an
● AMH <1.0 ng/mL predicts baseline
ovarian reserve with a likelihood of limited
eggs at retrieval.
● AMH >1.0 ng/mL but <3.5 ng/mL
suggests a good response to stimulation
AMH >3.5 ng/mL predicts a vigorous
response to ovarian stimulation and
caution should be exercised in order to
avoid ovarian hyperstimulation syndrome.
61. Assessment of the uterine cavity
Modalities to assess the uterine cavity
Saline Infusion Sono-

62. Laparoscopy as a diagnostic tool in
infertility has diminished markedly
Today, we rarely perform diagnostic laparoscopy in
infertile women. (Tulandi, 2017)
1.The benefit of diagnostic laparoscopy with no risk
factors for intra-abdominal adhesions: small.
2.Treatment of stage I or II endometriosis: small
increase in PR.
3.Alternative treatments of infertility are available
1.Abnormal HSG or US
2.Young women with history or symptoms
suggestive of pelvic disease. Even if HSG
indicates patency in one or both tubes
.A history of PID,
.Chronic pelvic pain
. Current dysmenorrhea, pelvic pain, or deep
dyspareunia; previous complicated appendicitis

4. After failed IVF
-Laparoscopy after failed IVF:(Littman et al.,
Pathology in 50%
endometriosis or adhesions
No RCTs have confirmed this rate.
65. TESTS OF LIMITED CLINICAL
PCT for assessment of the cervical factor.
Chlamydia trachomatis antibodies .
Basal body temperature records
Zonafree hamster oocyte penetration test
Testing for antibodies; antiphospholipid, antisperm,
antinuclear, and antithyroid antibodies.
Lack of agreement exists among
trained infertility specialists with regard
to prognostic utility as well as criteria of
normality of many of these tests?
There is no consensus on which tests
are essential before reaching the exact

allocation of the treatments or other factors being studied.
69. 1-Semen analysis
• CASA is not superior to conventional
semen analysis (Grade A)
• Screening for antisperm antibodies
should not be offered because there is
no evidence of effective treatment to
improve fertility. (GPP)
70. What To Do if Semen analysis Is
Repeat confirmatory test ( 3 months after
the initial analysis & ttt). (Grade B).
If azoospermia or severe oligozoospermia ,
repeat test as soon as possible. (GPP)

72. 2-Assessment of Ovulation
Women with regular monthly menstrual
cycles are likely to be ovulating. (Grade
The use of basal body temperature
charts to confirm ovulation does not
reliably predict ovulation and is not
recommended. (Grade B)
73. Assessment of Ovulation
Women with regular menstrual cycles and
more than 1 year’s infertility are offered a
blood test to measure serum progesterone
in the mid-luteal phase of their cycle (day
21 of a 28-day cycle) to confirm ovulation.
74. Assessment of Ovulation
Ovulation is most easily documented by a
midluteal phase serum progesterone level,
which should be obtained approximately one
week before the expected menses.
For a typical 28day cycle, the test would be
obtained on day 21. A progesterone level >3
ng/mL is evidence of recent ovulation.
75. Assessment of Ovulation
Women with irregular menstrual cycles
should be offered a blood test to measure
serum FSH & LH (GPP).
Blood test for prolactin should only be
offered to women who have an ovulatory
disorder, galactorrhoea or a pituitary
tumor. (Grade C)
76. Assessment of Ovulation
Tests of ovarian reserve currently have limited
sensitivity and specificity in predicting fertility.
However, women who have high levels of
gonadotrophins should be informed that they
are likely to have reduced fertility. (Grade C)
The value of assessing ovarian reserve using
Inhibin B is uncertain and is therefore not
recommended. (Grade C)
77. Assessment of Ovulation
Women with possible fertility problems are no
more likely than the general population to have
thyroid disease and the routine measurement of
thyroid function should not be offered.
Estimation of thyroid function should be
confined to women with symptoms of thyroid
disease. (Grade C).
78. Assessment of Ovulation
Women should not be offered an
endometrial biopsy to evaluate the luteal
phase as part of the investigation of
fertility problems because there is no
evidence that medical treatment of luteal
phase defect improves pregnancy rates
79. 3-Assessment of tubal factor
Women who are not known to have co-
morbidities should be offered HSG to
screen for tubal occlusion because this
is a reliable test for ruling out tubal
occlusion, and it is less invasive and
makes more efficient use of resources
80. Assessment of tubal factor
Where appropriate expertise is available,
screening for tubal occlusion using
should be considered because it is an
effective alternative to HSG for women
who are not known to have co-morbidities
81. Assessment of tubal factor
Women who are thought to
have co-morbidities should be
offered laparoscopy and dye so
that tubal and other pelvic
pathology can be assessed at
the same time. (Grade B)
82. 4-Assessing uterine abnormalities
Women should not be offered
hysteroscopy on its own as part of the
initial investigation unless clinically
indicated, because the effectiveness of
surgical treatment of uterine abnormalities
on improving pregnancy rates has not
been established. (Grade B)
83. Unnecessary laparoscopy!!!
It is not cost effective to do
diagnostic laparoscopy as part of
the initial infertility evaluation
History, and physical examination,
TVS, HSG, and Midluteal progesterone
are all normal (Grade B)

90. The basic infertility evaluation of
all couples consists of:
Assessment of ovulatory function
Determination of tubal patency and presence or absence
of abnormalities of the uterine cavity,usually by HSG.
Diagnostic laparoscopy is indicated for women with
suspected endometriosis or pelvic adhesions.
Ovarian reserve is assessed with day 3 (FSH) and
estradiol levels in women over 35 years of age and in
younger women with risk factors for premature ovarian
