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.
www.smso.net
Investigations of Male Factor• Conventional semen analysis• Computer- assisted sperm analysis (CASA)• Strict sperm morphology "Tygerberg strict criteria“• 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 - etc.• A variety of imaging techniques for detection of varicocele
www.smso.net
Assessment of ovulation• Basal body temperature• Urine LH kits• Mid luteal serum progesterone• Routine hormonal profile: FSH, LH, Prolactin,TSH• Endometrial biopsy • Serial pelvic Ultrasonography.• A variety of tests for assessment of ovarian reserve such as D3
FSH & E2, Inhibin B, Clomid challenge test, Gondotropin agonist stimulation test, TVS for ovarian volume, antral follicle count and Stromal blood flow.

Investigations of tubal factor• Hysterosalpingography (HSG)• Hysterosonography • Laparoscopy• Hydrolaparoscopy. • Falloscopy
www.smso.net
Other investigations• PCT for assessment of the cervical factor. • Hysteroscopy and 3 D US for assessment of the
uterine factor.• Laparoscopy for assessment of the peritoneal factors.• Chlamydia trachomatis antibodies for assessment of
possible tubo-ovarian adhesions.• CA-125 blood testing for assessment of possible
endomtetriosis.• Immunological factors are evaluated by a variety of
special tests.

Controverses Lack of agreement exists among
trained infertility speicalists 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 diagnosis ?

• GPP Good practice point : The view of the Guideline Development Group
www.smso.net
Semen analysisThe results of semen analysis conducted as part of aninitial assessment should be compared to the followingWHO reference values :
• volume: 2.0 ml• liquefaction time: within 60 minutes• pH: 7.2• sperm concentration: 20 million per ml• total sperm number: 40 million per ejaculate• motility: 50% (grades a and b) or 25% or more with progressive
motility (grade a) within 60 minutes of ejaculation• vitality : 75% or more live• white blood cells: fewer than 1 million per ml • normal morphology: 30% or 15% (based on strict morphological criteria)
www.smso.net
Semen analysis• If the result of the first semen analysis is abnormal,
a repeat confirmatory test should be offered. (Grade B)
• Repeat confirmatory tests should ideally be undertaken 3 months after the initial analysis to allow time for the cycle of spermatozoa formation to be completed. However, if a gross spermatozoa deficiency (azoospermia or severe oligozoospermia) has been detected the repeat test should be undertaken as soon as possible. (GPP)
www.smso.net
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)
www.smso.net
Assessment of Ovulation Women with fertility problems should
be asked about the frequency and regularity of menstrual cycles.
• Women with regular monthly menstrual cycles are likely to be ovulating. (Grade B)
• The use of basal body temperature charts to confirm ovulation does not reliably predict ovulation and is not recommended. (Grade B)
www.smso.net
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. (Grade B)
www.smso.net
Assessment of Ovulation• Women with prolonged irregular menstrual cycles
should be offered a blood test to measure serum progesterone. Depending on the timing of menstrual periods, this test may need to be conducted later in the cycle (for example day 28 of a 35-day cycle) and repeated weekly thereafter until the next menstrual cycle starts. (GPP)
For such women direct or indirect measurement of progesterone is unnecessary until after therapy is
initiated.
www.smso.net
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 tumour. (Grade C)
www.smso.net
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)
www.smso.net
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).
www.smso.net
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 (Grade B).
www.smso.net
Assessment of tubal factor
The results of semen analysis and assessment of ovulation should be known before a test for tubal patency is performed.
• Women who are not known to have co-morbidities (such as pelvic inflammatory disease, previous ectopic pregnancy or endometriosis) 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 than laparoscopy. (Grade B)
www.smso.net
Assessment of tubal factor• Where appropriate expertise is available, screening
for tubal occlusion using hysterosalpingo-contrast-ultrasonography should be considered because it is an effective alternative to HSG for women who are not known to have co-morbidities (Grade A)
www.smso.net
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)
www.smso.net
Screening for Chlamydia trachomatis
• Before undergoing uterine instrumentation women should be offered screening for Chlamydia trachomatis using an appropriately sensitive technique. (Grade B)
• If the result of a test for Chlamydia trachomatis is positive, women and their sexual partners should be referred for appropriate management with treatment and contact tracing. (Grade C)
• Prophylactic antibiotics should be considered before uterine instrumentation (including HSG), if screening has not been carried out. (GPP)
www.smso.net
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)
women with infertility and a normal HSG had no abnormalities of the uterine cavity when subsequently
examined by hysteroscopy.
www.smso.net
Post-coital testing of cervical mucus
• The routine use of post-coital testing of cervical mucus in the investigation of fertility problems is not recommended because it has no predictive value on pregnancy rate. (Grade A)
. The post-coital test may be of value in the diagnosis of sexual dysfunction and ejaculatory problems.
. Results of post-coital testing may have little influence on treatment strategy in the light of the widespread use of IUI for fertility problems associated with sperm-cervical mucus interaction.
. The lack of effective treatment for anti-sperm antibodies may render PCT unnecessary.

www.smso.net
Until it is demonstrated conclusively that treatment of abnormalities diagnosed by any of infertility
testing, results in a significantly better pregnancy rate than placebo or no treatment, the advisability of
performing such test, remains unproven and should not be
performed.
www.smso.net
Conventional Semen analysis.Assessment of utero-tubal status by
HSG and indicated laparoscopy. Mid luteal progesterone for the
diagnosis of ovulation Are useful tests, and correlate directly
with the likelihood of conception.
www.smso.net
Post-coital test. Sperm penetration into cervical mucus.
Hysteroscopy. Sperm antibody tests.
Varicocele assessment. Endometrial biopsy.
The sperm penetration assay in the zona-free hamster oocyte.
Are less useful tests, as their results are not correlated with pregnancy.
www.smso.net
It is not cost effective to perform a diagnostic laparoscopy as part of the initial infertility evaluation
in women in whom, history, and physical examination, TVS, HSG, antibodies to Chlamydia trachomatis and
CA-125 level are all normal. Provided the woman is under age 35 and having
ovulatory cycles and patent tubes, and there are more than 5 million motile sperm in the ejaculate of the male partner, 4-6 cycles of IUI COH should be undertaken
before performing a diagnostic laparoscopy and resorting to ARTs.
Such approach has been shown to increase fecundability rates to 10 - 25% per cycle and is thus
useful initial approach for subfertile couples.
www.smso.net
Research could help improve treatment results in female infertility by discovering as-yet-unknown causes of infertility that coexist
with recognized diagnoses. Such unknown causes may include post-fertilization defects that cannot by definition respond to the pre-fertilization interventions
that comprise many of the available treatments.
www.smso.net
Care must be taken to avoid exploitation of the infertile couple with expensive unnecessary tests
A simplified approach will lead to a significant reduction in both the time and cost of
investigating an infertile couple.
The diagnostic process of investigating infertilityhas evolved more by discarding old tests than by
finding useful new ones
