  1. Inserm Unit 845, Research Center Growth & Signaling, Faculty of Medicine Necker, Paris Dept Endocrinology & Reproductive Medicine, Hospital Pitié Salpetrière, Paris Premature Ovarian Failure Santiago, October 5th, 2007 Pr Philippe Touraine philippe.touraine@psl.aphp.fr

  2. 5 th Week of embryogenesis Endodermal stem cells Genital crest Ovogonia Oogonia Mitosis Meiosis Atresia Maximal at 20thWeek 28th Week Primary Oocytes 8th week : 600 000 oogonia

  3. 6-7 Million germ cells at 20th Week • 2/3 are oocytes in meiosis • 1/3 are oogonia Atresia • < 20 % germ cells at birth la naissance • 300 000 at puberty • 400-500 follicles during genital life

  4. Premature Ovarian Failure (POF) • WHO : Permanent Cessation of menstruations secondary to loss of follicular activity • Characterized by : • Women < 40 yrs • Amenorrhea > 4 months • Hypergonadotrophic Hypogonadism (FSH > 30 UI/L) Anasti JN, Fertil. Steril., 1998, 70 : 1-5. • Incidence : # 1% Coulam CB et al., Obstet. Gynecol., 1986, 67 : 604-6

  5. Autoimmunity FSHR anomalies Cx37, GDF9, BMP-15 Enzyme deficiencies Follicular Depletion Chemotherapy X chromosome anomalies Autoimmunity Follicular Dysfunction Accelerated atresia Premature Ovarian Failure 1% of 40-year-old-women Etiology most often remains unknown

  6. Follicular Depletion Chemotherapy X chromosome anomalies Autoimmunity Accelerated atresia Premature Ovarian Failure

  7. % cases with POF Total of cases with POF Primary amenoorhea Secondary amenorrhea Schlessinger et al., Am J Med Genet, 2002

  8. POF - FMR1 • 20% premutated and 14% grey zone develop POF (Bretherick, 2005) • 13-21% familial forms POF are premutated • 3-7% sporadic POF are premutated (Shermann, 2000) • Prevalence: 0.4% women with normal fertility

  9. Drugs Normal Cycles Normal cycles Oligomenorrhea Amenorrhea POF and chemotherapy Radiotherapy : 6 Gy on ovaries : non reversible POF

  10. Autoimmunity FSHR anomalies Cx37, GDF9, BMP-15 Enzyme deficiencies Follicular Dysfunction Premature Ovarian Failure

  11. Genetics of POF • Is there any argument for a genetic compound • Genes and physiological menopause • Correlation between age of menopause in mother and girls De Bruin, Hum Reprod 2001 • Cohort of twins: POF described in up to 63% Snieder, J Clin Endocrinol Metab 1998 Gosden R, Hum Reprod, 2007 • Familial cases in 15 to 20%

  12. Ovulation Blocade of follicular maturation Antral Secondary Primary Primordial Atresia Hsueh, Endocrine Review, 2000

  13. Ala189 Val NH2 COOH FSH receptor gene mutation in the Finnish population • 22 patients with primary amenorrhea • Pubertal development variable • Hypoplasic ovaries at histological examination • Presence of primordial and primary follicles

  14. Setting up a POF Network • Phenotyping of the patients (specificities of subgroups) • Constitution of a DNA Bank • Identification of new mutations of genes involved in folliculogenesis • Constitution of an ovarian tissue bank • Immunohistochemistry / steroidogenesis • Ovarian transcriptome • Prospective follow-up of population

  15. Clinical Phenotype Biological Phenotype Morphological Phenotype Questionnaire Karyotype Hormonal evaluation Ultrasonography Laparoscopy - Histology Current Evaluation

  16. 351 patients • 50 excluded • 40 yrs • FSH<30 mUI/l • Secondary POF • Karyotype “Turner-like” 74 patients < 18 yrs (25%) 301 patients 8 karyotypic anomalies 293 46,XX  idiopathic Bachelot et al., 2007, submitted

  19. Clinical Phenotype • 41 patients with a history of familial POF • 13.6% des POF • 59 patients with autoimmunity biomarkers • 19.6 % of POF • 37 with thyroid disorders • Diabetes, juvenile arthritis, vitiligo,…. • 6 patients with antiovarian antibodies (IFI) • 41 patients with fluctuating POF • 5 pregnancies; 3 births

  20. 134 woman have detectable E2 levels and 58 inhibin B • AMH detectable in 105 patients Bachelot et al., 2007, submitted

  21. Bone Mineral Density • Available for 151 patients • Mean age 28.7 yrs (15-42) • Definition WHO • 66 patients (42%) BMD normal • 63 patients osteopenia (42%), 14 at neck and 25 at lumbar • 22 patients osteoporosis (15%), 7 at neck and 20 at lumbar

  26. Phenotype-Genotype Correlation

  27. Rec FSH Stimulation

  28. Etiology actually possible in 30 patients (10%) • 8 with karyotype anomalies • 5 with FMR1 premutation • 16 anomalies of genes involved in POF • 2 APS type 2, 1 with multiple AI diseases

  29. What to do in our current practice? Clinical evaluation: Height Familial POF syndrome, Syndromic defects, Autoimmunity Karyotype Hormonal evaluation: FSH-E2; Androgens AMH, Inhibine B Ultrasonography: Surface, Presence of Follicles Evaluation of BMD DNA analysis: XFra FSHR analysis in patients with presence of follicles at ultrasonography Hormonal substitution Treatment of infertility Bachelot et al., 2007, submitted

  30. What to say? • Information +++ • Psychological help • HRT • Explanation about pregnancy plans (oocyte donation…) • Discussion about “ovaries to be frozen”
