Symptomatology of male infertility • TYPE I – erection problems (0,3-7%) • TYPE II – azoospermia (0,9%-16%) • TYPE III – immunological infertility (3,4%-25%) • TYPE IV – abnormal seminal quality (23%-48%) • TYPE V – idiopathic sperm dysfunction (0-25%)
Diagnosis • General examination • Semen analysis • Other diagnostic tests: • USG • Hormonal diagnostic • Diagnostic tests for Assisted Reproductive Technology
TYPE I – erection problems (0,3-7%) • Normal ejaculation • Hypospermia (semen volume < 2,0 ml) – chronic prostatitis • Impotence • Retrograde ejaculation • Neurogenic– DM, SM • Anatomical • Jatrogenic – drugs, operations • disejaculation • Functional – anorgazmia • Neurogenic – spinal injury • Jatrogenic – drugs, chemiotherapy, radiotherapy, operations
TYPE II – azoospermia (0,9%-16%) • Pre-testicular causes • Hypothalamic or pituitary disorder – LH, FSH deficiency, Kallman syndrome, trauma, tumors, inflammation, meningitis • Testicular causes • Primary testicular failure • Congenital – 47XXY, del Y, AZF • Acquired- mumps, testicular torsion, castration • Jatrogenic – radiotherapy, chemiotherapy • Post-testicular causes • Congenital – CBAVD, CF • Acquired – inflammations (gonorrhea) • Jatrogenic – vasectomy, hernia operation
Diagnostic tests for Assisted Reproductive Technology- ICSI • FSH • If < 12IU – sperm biopsy is effective in 80-90% • Blocked ejaculatory duct (Micro-Epidydymal Sperm Aspiration –MESE) • Other (Testicular Sperm Extirpation- TESE, Testicular Sperm Aspiration- TESA)
TYPE III – immunological infertility (3,4%-25%) • antisperm antibodies – the immune system may produce antibodies that attack and weaken or disable sperm • Auto-immunological diseases • Concequences of testicular trauma
Congenital Undescended testicles Sexually transmitted disease (gonorrhoea) or testicular infection (mumps) Vascular Testicular torsion Varicocoeles Diseases: Thyroid faiure; Addison disease, hepar diseases; DM, auto-immunological diseases; Environmental factors Drugs (sulfasalazine, T, chemiotherapy) Temperature Other factors (X-rays, lead, cigarette smoke, alcohol; marijuana, frequently wearing tight-fitting pants and underwear) Immunological Testitis Genetic del Y, aberrations (count and structure of chromosomes) Idiopathic [46%] TYPE IV – abnormal sperm quality (23%-48%)
Treatment • Risk factor elimination • Give up smoking • Testicular temperatue decrease • Regular sexual intercourses (2-3 per week) • Antioxydants • Vitamin E, C, Zinc • Tetracicline • Chlamydia Trachomatis infection
Treatment (pharmacotherapy) • Risk factor elimination • Hormonal treatment • Testosterone • hCG • FSH • C.C, tamoxyphen
Varicose veins in the spermatic cord • Physical examination • I Valsalva test examination ( or during cough) • II large veins during palpation • III visible varicouse veins • Other diagnostic test • Semen analysis (SA) • USG • Treatment • Operation • ART.: IUI, IVF, ICSI
Diagnostic and therapeutic algorithm (female) Sperm analysis IUI Treatment: operation, CC, hMG (FSH) O, A, T, OA, OT, TA, OAT grave O, A, T, OA, OT, TA, OAT ICSI azoospermia Testicular cells? TESE, MESA
Sperm analysis- recommendation by WHO • General female infertility diagnostic test- SA • sterility • sample should be delivered to laboratory in 60 min. after ejaculation • abstinence min. 48 hours max. 7 days • the next semen analysis between 7 days and 3 months
liquefaction viscosity volume color pH smell Sperm count Sperm motion analysis WBC count (pyospermia) Spermatozoa count Antisperm antibodies Sperm morphology Microbiology Seminal quality, cytology and sperm quantitation
Semen analysis • Microscope • Makler counting chamber • Immunobead test (IgG, IgA or IgM) • CASA (computer-assisted sperm analysis)
Sperm motion analysis 0- immotile 1- weak movement with no forward progression 2- weak to moderate forward progression 3- good forward progression; active tail movement 4- rapid forward progression; vigorous tail movement
Seminal quality- ranges • Liquefaction < 60 minutes • Volume > 2 ml • Color- gray to white opalescent fluid • pH 7,2 – 8,0
IMMUNOBEAD TEST Microscopic polyacrylamide spheres, ranging in size from 2 to 10 um, coated with anti-human immunoglobins against human IgG, IgA or IgM
Normal sperm range • Motility >50% 4 or 3 ; or >25% 4 • Sperm count >20·106/ml • WBC count <106/ml • Spermatozoa <5·106/ml • Autoagglutinating <10% • Immunebead test <10% • Sperm morphology >30% normal forms (WHO); 5-14% strict criteria (Kruger)
Definitions of „abnormal” counts • Normozoospermia • Oligozoospermia <20·106/ml • Astenozoospermia <50% 4 or 3 ; or <25% 4 • Teratozoospermia <30% • Azoospermia no sperm
