    Evidence Based Medicine


  • 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.

  • Investigations of Male FactorConventional semen analysisComputer- assisted sperm analysis (CASA)Strict sperm morphology "Tygerberg strict criteriaA 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

  • Assessment of ovulationBasal body temperatureUrine LH kitsMid luteal serum progesteroneRoutine hormonal profile: FSH, LH, Prolactin,TSHEndometrial 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 factorHysterosalpingography (HSG)Hysterosonography LaparoscopyHydrolaparoscopy. Falloscopy

  • Other investigationsPCT 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 ?

  • Investigations of infertile couple Evidence Medicine Based EraNational Evidence-Based Clinical GuidelinesAssessment and treatment for people with fertility problems developed by the National Collaborating Centre forWomen and Children's Health on behalf of the National Institute for Clinical Excellence (NICE)February 2004


  • Grading Evidence Based Recommendations GPP Good practice point : The view of the Guideline Development Group

    A recommendationI evidenceB recommendation II evidenceC recommendation III evidenceD recommendation IV evidenceI a- meta-analysis of RCTs trials,I b- at least one RCT.II a - at least one controlled study without randomisation II b - at least one other type of quasi-experimental studynon-experimental descriptive studies, such as comparative studies, correlation studies and case control studiesfrom expert committee reports or opinions and/or clinical experience of respected authorities

  • Semen analysisThe results of semen analysis conducted as part of aninitial assessment should be compared to the followingWHO reference values :volume: 2.0 mlliquefaction time: within 60 minutespH: 7.2sperm concentration: 20 million per mltotal sperm number: 40 million per ejaculatemotility: 50% (grades a and b) or 25% or more with progressive motility (grade a) within 60 minutes of ejaculationvitality : 75% or more livewhite blood cells: fewer than 1 million per ml normal morphology: 30% or 15% (based on strict morphological criteria)

  • Semen analysisIf 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)

  • Semen analysisCASA 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)

  • Assessment of Ovulation Women with fertility problems shouldbe 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)

  • Assessment of OvulationWomen with regular menstrual cycles and more than 1 years 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)

  • Assessment of OvulationWomen 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.

  • Assessment of OvulationWomen 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)

  • Assessment of OvulationTests 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)

  • Assessment of OvulationWomen 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).

  • Assessment of OvulationWomen 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).

  • 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)

  • Assessment of tubal factorWhere 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)

  • Assessment of tubal factorWomen 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)

  • 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)

  • Assessing uterine abnormalitiesWomen 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.

  • Post-coital testing of cervical mucusThe 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.
