Definitions Infertility should be defined as ‘failure to conceive after regular unprotected sexual intercourse for two years in the absence of known reproductive pathology’
Definitions The duration of the failure to conceive should be twelve or more months before an investigation is undertaken unless medical history and physical findings dictate earlier evaluation and treatment. Primary Infertility: no previous pregnancies have occurred Secondary Infertility: a prior pregnancy has occurred
Statistics 84% of couples conceive within 12m, 92% will do so in 24m. Fertility decreases with age and more so after 35 years. Origin: Female factor ~ 40% Male factor ~ 30% Combined ~ 30%
Etiologies Sperm disorders 30% Anovulation / oligoovulation 30% Tubal disease 16% Unexplained, Cervical factors, and other factors account for 24%
Etiological Factors Pelvic inflammatory disease Endometriosis Spermatic varicocoele ? Primary ovarian failure Previous tubal/abdominal surgery Cervical and uterine abnormalities Fibroids ?
History taking Both partners should be present Most important part of infertility evaluation Fertility history: duration of infertility Obstetric history: number and outcome of previous pregnancies, postpartum or miscarriage complications Menstrual history: age at menarche, regularity, duration and amount of bleeding, abnormal bleeding.
History taking Contraceptive history. History of medical illnesses. Family history of genetic diseases. Personal history: smoking, alcohol, drug abuse. Sexual history: knowledge, frequency, dysparenuia, vaginismus. Gynaecological history: PID, STI. History suggestive of ovulatory disorders: exercise, cyclical pelvic pains, hot flushes, hirsutism, galactorrhoea, stress, eating disorders, stress, eating disorders.
History taking in Male partner Sexually transmitted infections Testicular surgery/injury History of Mumps Radiation, cytotoxic drugs usage, exposure to toxic substances Excessive heat exposure
Initial Advice Natural conception Frequency and Timing of sexual intercourse Alcohol consumption Smoking Caffeinated beverages Tight underwear for men Body weight Occupation
Initial Advice Prescribed, over-the-counter and recreational drug use Complementary therapy Folic acid supplementation Susceptibility to rubella Cervical cancer screening
Assessment and Referral Failure to conceive at 1yr History of predisposing factors Known reason for infertility Chronic viral infections
Principles of care Disease of couples, not individuals Emotional and Educational Needs Feelings of guilt, frustration and anger Support groups and counseling
Investigation of fertility problems and management strategies
Semen Analysis Volume: 2.0 ml or more Liquefaction time: within 60 minutes pH: 7.2 or more Sperm concentration: 20 million spermatozoa per ml or more Total sperm number: 40 million spermatozoa per ejaculate or more
Motility: 50% or more motile, or 25% or more with progressive motility within 60 minutes of ejaculate Vitality: 75% or more live White blood cells: fewer than 1 million / ml Morphology: 15% or 30% Screening for anti-sperm antibodies Repeat confirmatory tests
Physical Exam-Female Pelvic masses Uterosacral nodularity Abdominopelvic tenderness Uterine enlargement Uterine mobility Cervical abnormalities Thyroid exam
Assessing Ovulation Menstrual history Regular menstrual cycles + 1yr infertility Irregular menstrual cycles BBT not recommended FSH, LH, Prolactin, Inhibin B, TSH Endometrial biopsy
Screening for Chlamydia trachomatis Before uterine instrumentation Appropriate management Prophylactic antibiotics
Assessing Tubal Damage Women with out co-morbidities should be offered HSG Hysterosalphingo-contrast ultrasonography Laparoscopy and dye The results of semen analysis and assessment of ovulation should be known before a test for tubal patency is performed.
Assessing uterine abnormalities Post-coital testing of cervical mucus
Physical Exam-Male Testicular descent and its size Presence of varicocoele Urinary tract abnormalities Signs of STI
Medical and surgical management of male factor fertility problems Men with hypogonadotrophic hypogonadism should be offered gonadotrophin drugs Idiopathic semen abnormalities Men with antisperm antibodies Men with leucocytes in their semen Obstructive azoospermia, Varicocoele Ejaculatory failure
Classification of Ovulatory Disorders Group Ι: Hypothalamic pituitary failure Group Ι Ι: Hypothalamic pituitary dysfunction (e.g. PCOS) Group Ι Ι Ι: Ovarian failure
Ovulation Induction Anti-estrogens for Group Ι Ι ovulation disorders (clomifene citrate or tamoxifen) Risk of multiple pregnancy Chance of pregnancy increases with unexplained infertility Ultrasound monitoring for the first cycle
Metformin & Ovarian Drilling Metformin is not currently licensed for the treatment of ovulatory disorders in the UK. Anovulatory women with PCOS, who have not responded to CC and with BMI >25 should be offered Metf combined with CC Women with PCOS who have not responded to CC should be offered with Laparoscopic Ovarian Drilling
Gonadotrophins PCOS women who failed to ovulate with CC or Tamoxifen should be offered GT PCOS women who ovulate but failed to become pregnant in 6m should be offered CC stimulated IUI PCOS women should not be offered concomitant GT and GT-RH agonists
Pulsatile GT-RH & Dopamine agonists Women with Group Ι ovulatory disorders should be offered pulsatile GT-RH or GT with luteinising hormone activity Pulsatile GT-RH in CC resistant PCOS women is not recommended Women with ovulatory disorders due to hyperprolactinaemia should be offered bromocriptine
Monitoring Ovulation Induction Risk of multiple pregnancy and ovarian hyperstimulation Ovarian ultrasound monitoring
Other risks and side effects associated with ovulation induction agents Risk of ovarian cancer uncertain Lowest effective dose and duration of use
Tubal and Uterine Surgery Tubal microsurgery and laparoscopic tubal surgery Tubal catheterisation or cannulation Hysteroscopic adhesiolysis
Medical & Surgical management of Endometriosis Medical treatment of minimal & mild E is not recommended Women with minimal or mild E who undergo laparoscopy, E ablation or resection with adhesiolysis should be offered Ovarian endometriomas-lap cystectomy Surgery should be offered to women with moderate or severe E
