Investigations to evaluate Infertility Dr Atin Singhai Assistant Professor Department of Pathology KGMU, Lucknow
Background • Definition: • 1 yr unprotected coitus without conception • 10-15% couples affected • Etiology • Couples: • 35% Tubal and pelvic pathology • 35 % Male problems • 15% Ovulatory dysfunction • 10% Unexplained • 5% unusual causes
Background • Etiology • Women: • 40% Tubal and pelvic pathology • 40% Ovulatory dysfunction • 10% Unexplained Infertility • 10% Unusual causes • Normal couple: • 25-30% chance of pregnancy per ovulatory cycle • Fertility decreases with age
Infertility Time of Exposure% Pregnant 3 months 60% 6 months 70% 1 year 85% 18 months 90%
Approach to Infertility • DDX • Tests/Inv • Dx • Rx
Approach to Infertility • Production • Storage • Delivery
Male Infertility 1. Production: • Hypothalamus • Anterior Pituitary • Testes
Male Infertility • 1. Production • Hypothalamus • Congenital abnormalities of hypothalamus • e.g. Kallman’s syndrome • Starvation, stress or severe illness • Tumors (craniopharyngioma, metastatic tumor) • Head injury • Inflammation (sarcoidosis) • Infection (tuberculosis) • Drugs: marijuana
Male Infertility • 1. Production: • Pituitary • Endocrine: thyroid, prolactin • Tumors • Inflammation: sarcoidosis, meningitis • Infiltration • Infarction • Trauma/XRT • Drugs: anabolic steroids
Male Infertility • Production: • Testes: • Congenital: Klinefelters (XYY), developmental disorders • Disorders of gonadal steroidgenesis • Infection: chlamydia, prostatitis, mumps orchitis • Autoimmune • Cryptorchidism • Tumors; chemo/XRT • Drugs / alcohol • Vascular: testicular torsion
Male Infertility • 2. Storage: • Temperature • Rise in scrotal temperature • Occupation • Varicocoele
Male Infertility • 3. Delivery: • Impotence/Ejaculation • Neurogenic: medications (α-blockers, methyldopa) • Endocrine: diabetes • Congenital: absence vas deferens (CF) • Genetic: cystic fibrosis • Primary ciliary dyskinesia: Kartagener syndrome • Hypospadia • Vasectomy
Male Infertility • History: • Previous children • Infections: prostatitis, STD, mumps orchitis • Trauma to head or testicles • Surgery to testicles or hernia • Occupation (sitting, bio hazards) • Chemo or Radio therapy • Ethanol or Smoking • Medication • Medical history (DM, HTN) • Previous investigations
Male Infertility • Physical • Anatomy (meatus) • Testicular size • Varicocele (valsalva) • Rectal exam (protatitis, discharge)
Male Infertility • Investigations: • semen analysis • Abstain 2-4 days prior • At least 2 samples over different period of time • If abnormal: • Blood work: FSH, LH, TSH, testosterone, PRL • Testicular U/S • Chromosomal analysis
Male Infertility • Semen analysis: • WHO (1992) • Volume > 2.0 mL • Sperm > 20 million/mL • Motility > 50% forward progression or > 25% rapid progression within 60 min • Morphology > 30% normal forms • WBC < 1 million/mL
Male Infertility • Tx / Interventions: • Treat underlying causes • Intrauterine Insemination (IUI) • Intracytoplasmic Sperm Injection (ICSI)
Female Infertility • Fecundability: probability of achieving a pregnancy within 1 menstrual cycle (25%) • Fecundity: ability to achieve a live birth within 1 menstrual cycle (6%)
Female Infertility • Production • Storage • Delivery
Female Fertility • Production: • Hypothalamus • Pituitary • Ovary
Female Infertility • Hypothalamus: • Stress • Exercise • Eating disorders • Psychogenic • Congenital/genetic: Kallman’s syndrome (hyposmia & hypoplasia olfactory lobes of brain) • Starvation/stress or severe illness • Tumors (craniopharyngioma, metastatic tumor) • Head injury • Inflammation (sarcoidosis) • Infection (tuberculosis) • XRT • Drugs
Female Infertility • Pituitary: • Sheehan syndrome • Tumors: Pituitary adenoma, metastatic • Empty sella syndrome • Inappropriate gonadal steroid feedback: • estrogen excess: obesity/ tumors • estrogen deficiency: aromatase deficiency/ ER gene mutation • androgen excess: adrenal or ovarian • PCOS • Testicular feminization (46 XY) - absenceandrogen receptors
Female Infertility • Ovary • Gonadal dysgenesis - Turner’s Syndrome 45XO or mosaics 46 XX/45 XO • Testicular feminization • XRT / Chemo for childhood malignancies • Premature ovarian failure
Female Infertility • Storage (R.P.L. unless severe) • Uterine abnormalities • Mullerian Agenesis: Mayer-Rokitansky-Kuster-Hauser syndrome • Leiomyoma • Luteal phase deficiency
Female Infertility • Delivery: • Uterine abnormalities • Vaginal septum • Tubal Disease • Infections/ STD/PID • Ruptured appendix • Septic abortion • Endometriosis
Female Infertility • History: • Age • GTPAL • Regulatory of period • Prolactin S/S • Thyroid S/S • Infections, Surgeries • Medication, Smoking, Ethanol • Medical history • Previous investigations
Female Infertility • Examination: • Thyroid • Breast (milk) • Abdomen (masses, scars) • Vaginal (abnormalities) • Bimanual (Uterus, masses)
Investigations • Blood work: • TSH • PRL • D3 FSH • D3 LH • Luteal phase Progesterone • Imaging: • Pelvic Ultrasound • HSG • Diagnostic • Laparoscopy (later)
Treatment • Treat the underlying cause • Medical • Surgical
Treatment • Anovulation: • Clomiphene induction IUI • Gonadotropin IUI • IVF • Bilateral tubal disease • Unexplained infertility after Gonadotropin + IUI failure. • Failure of the above • ICSI • Male factor • Unexplained infertility
Take Home Points • DDx – Hx – Px – Inv - Rx • Age is important factor for female • Hypothalamic-Pituitary-Gonadal axis central in working up both male and female infertility • Investigations: • Male: Sperms • Female: Tubes (HSG) + Ovaries (FSH, LH, PRL, TSH)
