  2. Poor Responders in PCOS Prof. Duru Shah MD FRCOG FCPS FICS FICOG FICMCH DGO DFP SMART OBGYN 16th April, 2016 Mumbai Org.by MOGS in asso. with SAFOG,FOGSI & AICRCOG

  3. Definition • Failure to respond adequately to standard protocols and to recruit adequate follicles is called “poor ovarian response”. • This results in decreased oocyte production, cycle cancellation and, overall it is associated with a significantly diminished probability of pregnancy. Ref: Shanbhag S. et.al. Cochrane Database Syst Rev. 2007;(1): CD004379

  4. 3 main groups Responses to Gonadotropins • Normal Responders When stimulated aggressively with Gn will develop 5-8 mature follicles as well as several smaller ones. • Poor Responders (older age, poor ovarian reserve) Failure to produce an adequate no. of mature follicles(<4) & or a peak E2 levels < 500 pg/ml. • High Responders (PCOS) Defined as those women with peak E2 levels > 4000 pg/ml on the day of hCG administration or > 15 retrieved oocytes

  5. Poor Responders • Concept of Poor Ovarian • Response introduced 30 yrs. • ago. • Results in ↑ cancellation rates • ↓ nos. of oocytes retrieved • ↓ preg. rates • Universal definition of Poor • Responders in 2011- • Bologna Criteria – ESHRE • WORKING group. Re. ASRM Fertil Steril, 2011, 96: 1058-61

  6. Bologna Criteria- 2011 • At least two of the following three features must • be present: • Advanced maternal age (≥ 40 yrs.) or any • other risk factor for POR. • A previous POR (≤ 3 oocytes with a • conventional stimulation protocol): • An abnormal ovarian reserve test (ie. AFC • <5-7 follicles or AMH <0.5-1.1 ng/ml) Ref. A.P. Ferraretti et. al. Human Reproduction Vol.26, No.7, pp.1616- 1624,2011

  7. Risk factors for Poor Ovarian Reserve • Age > 37 yrs., varies with • ethnicity. • Ovarian surgery • Endometriosis • Genetic Defects • Chemo / Radiotherapy • Autoimmune Disorders Contd… Ref. A.P Ferraretti et.al. Human Reproduction vol. 26, no. 7 pp 1616-1624,2011

  8. Declining follicle/oocyte numbers with advancing age. Ref : Gleicher et.al. Reproductive Biology & Endocrinology (2015) 13:34

  9. Genetic Defects • Under hormonal control • Genetic control which may either slow or hasten the process of recruitment • Genes identified currently are : - AMH type II – Receptor gene (AMHR2) - FMRI Gene ( Fragile X Mental Retardation Gene) - BRCA1 Gene Above Genes when mutated, blocked or knocked out, lead to rapid depletion of primordial follicles.

  10. Contd… Ovarian Surgery • Extensive Ovarian Drilling for PCOS • Prophylactic oophorectomy→ POF • Salpingectomy for ectopic pregnancy → ↓ AFC→↓ oocytes obtained during ART and for hydrosalpinx. • Ovarian Cystectomy for endometriomas. • Ovarian Neoplasms in Adolescents Contd…

  11. Contd… • Single Ovary • Chronic Smoking • New Factors proposed • Diabetes Mellitus Type I • N. Soto, G et.al. Human Rep. Vol. 24, no. 11 pp 2838-2844, 2009 • Transfusion dependant β Thalassemia • H.H. Chang, M-J et.al. British Journal of Obs. & Gyn. vol. 118,no7, • pp825-831 • Uterine Artery Embolization • W.J.J. Hehenkamp, et. al. Human Reproduction vol. 22, no.7, • pp1996-2007 Other Factors

  12. Identifying Poor Responders High Risk Group • Day 3 - FSH > 10 m IU /ml - Inhibin B < 45 pg/ml - AMH < 3 ng/mL - Total Antral Follicle Count < 10 • Age > 37 years of age - younger pts. may also have a poor response.

  13. Ultrasound –Antral Follicle count Ref : Kwee J et al Reprod Biology & Endocrinology 2007 5:9

  14. Hormonal investigations Contd.. Ref : Kwee J et al Reprod Biology & Endocrinology 2007 5:9

  15. Folliculogenesis Ref. A La. Marca et.al. Human Reproduction Update, Vol.16, 2010 No.2 pp 113-130

  16. Folliculogenesis • AMH corelates well with AFC, IVF out come. • AMH expression starts after growth initiation • of primordial follicles and disappears after the • small Antral follicles stage in the ovaries. Ref. Fanchin R. et. al. Hum. Reprod. 18, 323-327

  17. Folliculogenesis in PCOS • AMH significantly ↑ in PCOS reflecting ↑ • Primordial count. • Median density of primary follicles seen in • ovarian biopsies is 6 times ↑ in anovulatory • PCO v/s normal ovaries, suggesting • a larger ovarian reserve. Ref. Laven J. et.al. (2004) J. Clin Endocrinol Metab 89, 318-323

  18. Folliculogenesis in PCOS • Women with PCO are born • with a larger pool of resting foll. • - genetically determined process • which occurs in fetal life. • Larger the pool of Primordial • follicles → ↑ chance of PCOS in a certain environment. Contd.. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10 pp. 2175-2179,2004

  19. Folliculogenesis in PCOS • Women with PCO are unlikely to undergo a rapid depletion of their ovarian reserve too early. • Hence Poor responders to ovarian stimulation in PCO women are rarely seen. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10 pp. 2175-2179,2004

  20. Ovarian Aging • Normal Ovarian Ageing • → ↓oocyte quality and quantity rapidly in late • thirties. • Early Ovarian Ageing seen in 10% of women • → ↓ oocyte quantity which is faster than • qualitative decline before age 32 yrs. Contd.. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10, pp.2175-2179, 2004

  21. Early Ovarian Aging- are women with PCOS protected? • AFC- good predictor of ovarian response and • corelates well with chronological age. • PCO women have a higher no. of AFC • PCO ovaries tend to be larger and have ↑ peak • stromal blood flow velocityon Doppler studies. • PCOS women have ↑ Day 2 Inhibin B levels and • ↑ early follicular VEGF levels. Contd.. Ref. Nikolaou & Templeton A (2003) Hum Repro. 18, 1137-1139 Nikolaou D & Templeton A (2004) Eur J. ObstetGynaecol 113, 126-133

  22. Contd.. Early Ovarian Aging- are women with PCOS protected? • Using AMH + AFC • Women with PCOS perform better with ovarian • reserve tests as compared to women with normal • ovaries. • Poor response to ovarian stimulation is a • predictor of early ovarian ageing v/slarger • number of oocytes recruited during ovarian • stimulation, increasing the risk for developing • OHSS Contd.. Ref. Nikolaou & Templeton A (2003) Hum Repro. 18, 1137-1139 Nikolaou D & Templeton A (2004) Eur J. ObstetGynaecol 113,126-133

  23. Early Ovarian Aging- are women with PCOS protected? • PCO(older data) • → Large no. of follicles with compromised • quality due to ↓ fertilization rates • ↑ miscarriage rates • ↑ recurrent miscarriage rates • PCO (recent data) • Above true only if PCOS exists ie. Polycystic • ovaries (PCO) associated with • →menstrual irreg. • → Hyperandrogenism (PCOS) • → Associated Insulin Resistance (IR) Contd.. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10, pp.2175-2179, 2004

  24. Early Ovarian Aging- are women with PCOS protected? • More oocytes • More embryos • ↑ cumulative preg. rates • Similar miscarriages rates as • normal women. • Comparable oocyte quality • Time to pregnancy similar • Hence women with PCOS, but no clinical PCOS, • have a larger no. of good quality oocytes Ref. Rai et.al. 2000 Hum. Reprod. 15,612-615

  25. Clinical Pregnancy correlated with AMH & age – Our data ART : 369 pts. Ref. Gynaecworld data 2015-16

  26. Pregnancy rates correlated with Age + AMH (PCOS pts) Total no. of pts. 189 . Ref. Gynaecworld data 2015-16

  27. Pregnancy rates correlated with Age + AMH (Non PCOS pts) Total no. of pts. 180 . Ref. Gynaecworld data 2015-16

  28. Long-term follow-up of patients with PCOS syndrome: reproductive outcome and ovarian reserve • Study • 91 pts. with confirmed PCOS and 87 healthy controls included in the study. • Diagnosed bet 1987 and 1995, at the time of the follow-up subjects were 35 yrs. of age or older. Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  29. Contd.. Long-term follow-up of patients with PCOS syndrome: reproductive outcome and ovarian reserve Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  30. Long-term follow-up of patients with PCOS syndrome: reproductive outcome and ovarian reserve * p<0.025 ** p<0.01 ***p<0.001 Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  31. Contd.. Ovarian Volume Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  32. Contd.. Antral Follicles Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  33. AMH Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  34. Contd.. • Results: • Reproductive outcome did not differ between • women with a previous diagnosis of PCOS and • healthy control subjects. • Ovarian reserve better preserved in women • with PCOS • Live birth rate and rate of miscarriages similar in • PCOS patients and control women. Contd.. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  35. Contd.. • Results: • Mean ovarian volume and number of antral • follicles, significantly higher in PCOS patients. • PCOS patients have markedly higher serum • concentration of AMH. • More than two-thirds of the PCOS patients in the • present study reported at least one • spontaneous pregnancy. • PCOS patients have a good fecundity. Ref. M. Hudecova et.al. Hum. Repro. Vol.24, No 5 pp1176-1183,2009

  36. Conclusions • Recent findings support that, women with PCOS are born with a larger pool of resting follicles, almost certainly genetically determined. • The rate of decline of the ovarian reserve • depends on the number of remaining • primordial and small pre-antral follicles. Contd.. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10, pp.2175-2179, 2004

  37. Conclusions • Hence women with PCO are unlikely to • undergo a rapid depletion of their ovarian • reserve too early. • PCO most likely forms a low-risk group for • early ovarian aging and poor ovarian • response Contd.. Ref. D. Nilolaou et.al. Hum. Reprod. Vol. 19, No.10, pp.2175-2179, 2004
