Embryo Transfer Technologies and Luteal Phase Support to Maximize Pregnancy Rates

  1. 1. Embryo Transfer Technologies and Luteal Phase Support to Maximize Pregnancy Rates Sandro Esteves Androfert, Brazil
  2. 2. Learning objectives At the completion of this presentation, participants should be able to: Implement embryo transfer (ET) technologies and luteal phase support (LPS) as per quality management perspective Individualize embryo transfer and luteal phase support according to different patient segments
  3. 3. The ‘process’ is the only objective and measurable aspect of quality Process = Any activity or set of activities that uses resources to transform raw material, supplies and labor (inputs) into products or services (outputs)
  4. 4. Quality of ET and LPS strategy can be measured… We should use indicators for the most important quality dimensions in infertility care… Safety Patient centeredness Effectiveness
  5. 5. Basic question in a quality perspective is… What is the most effective, safe and patient-centered ET technique and LPS we should apply? Effectiveness includes technical aspects to deliver the best possible outcome (cumulative LBR) Safety includes complications (OHSS), adverse effects, risks (patient and offspring), errors/mistakes Patient-centeredness relates to physical burden and invasiveness of techniques for ET and LPS
  6. 6. What the doctor want to know Clinical Needs Determine procedures Write SOP Standard Operating Procedure sequence of steps that have been standardized to execute a task, which is used every time a given task is done, to ensure it is done the same way each time What is the most effective, safe and patient-centered ET/LPS?
  7. 7. • Catheter type, soft vs. rigid • US-guided ET • Full bladder • Removal of cervical mucus • Best embryo placement position • Antibiotics • Acupuncture • Post-embryo transfer interventions • Etc. What is the most effective, safe and patient-centered ET technique we should apply? ?
  8. 8. Moderate to high-quality evidence Buckett Fertil Steril. 2006; Abou-Setta et al Reprod Biomed Online 2007; Brown et al Cochrane Database Syst Rev 2010
  9. 9. Moderate to high-quality evidence Peri-ET Abou-Setta et al. Cochrane Database 2009; Derks et al Cochrane Database Syst Rev. 2009; Bontekoe et al Cochrane Database 2014

  11. 11. Are they beneficial as a routine? Antibiotics pre-ET Intrauterine hCG Pre-cycle hysteroscopy Trial transfer Endometrial scratching May be beneficial; Limited evidence to draw firm conclusion Mansour et al Steril 2011; Santibañez et al Reprod Biol Endocrinol. 2014; Pundir et al Reprod Biomed Online 2014
  12. 12. ET SOP at Androfert Abdominal US-guided Full bladder Soft catheter Sydney IVF, Cook Air-medium interface Small transfer volume ~15 microliters Modified-trial ET (previous cycle) Outer sheath of soft catheter advanced to just past the internal os
  13. 13. ET SOP at Androfert (cont.) Two-step ET Outer sheath soft catheter advanced to just past internal os Embryo load into the catheter Insertion of the loaded soft catheter into the uterine cavity Placement mid-portion of the uterus Two-step catheter withdrawal Soft catheter removed first (pressure on the syringe plunger maintained) while outer sheath withdrawn past internal os Laboratory check Rigid outer sheath removed and checked
  14. 14. Double-checking (DC) and Double-witness (DW) SOP at Androfert Identification by the nurse of the patient arriving at the ET room; Patient and husband fill in a form (name, dates of retrieval and ET) 1 Nurse and doctor performing the ET check ID info (DC) 2 Doctor explains embryos profile, and give recommendation for ET 3 Couple fill in No. embryos to be replaced and cryopreserved (in conformity with legislation) 4 Embryologist and doctor/nurse check information written (DC) 5 Embryologist removes couple’s embryos from incubator, and loads ET catheter, witnessed by a 2nd embryologist (DW) 6 Catheter tagged with patient name and No. embryos is given to doctor, who checks info (DC), witnessed by a nurse (DW) 7

  16. 16. Luteal Phase Support
  17. 17. Luteal phase of stimulated cycles is abnormal Supraphysiologic steroid levels (by multifollicular development) inhibits LH secretion Normal corpus luteum function dependent on pulsatile LH release from pituitary Low LH levels causes luteolysis, implantation failure and shortened luteal phase Adapted from Jones-1996 by Fauser and Devroey- 2003 Albano et al 1998; Beckers et al 2000; Tavaniotou et al Hum Reprod 2000; Trinchard-Lugan et al 2002; Sherbahn 2013
  18. 18. hCG vs. Placebo or No treatment Higher ongoing PR; OR=1.75 (95% CI: 1.09-2.81) Progesterone vs. Placebo or No treatment Higher clinical PR; OR=1.83 (95% CI: 1.29-2.61) Higher ongoing PR; OR=1.87 (95% CI: 1.19-2.94) Higher live birth rates; OR=2.95 (95% CI: 1.02-8.56) LPS mandatory in all stimulated cycles Level 1a van der Linden et al, Cochrane Database Syst Rev 2011:CD009154
  19. 19. Quality of LPS strategy can be measured… Agents and routes of administration Which dose and when to start and stop LPS What the doctor want to know Clinical Needs Determine procedures Write SOP What is the most effective, safe and patient-centered LPS?
  20. 20. High-quality evidence on LPS Gelbaya et al Fertil Steril. 2008; Kolibianakis et al Hum Reprod. 2008; Jee et al Fertil Steril. 2010; van der Linden et al Cochrane Database 2011
  21. 21. LPS with Progesterone is critical P alone enough for LPS Progesterone is a natural hormone secreted by the corpus luteum In the presence of estrogen, P transforms a proliferative into a secretory endometrium Progesterone increases the receptivity of the endometrium Once an embryo is implanted, progesterone acts to maintain the pregnancy
  22. 22. Routes/Type Evidence Effect Conclusion Vaginal P as effective as IM/oral? 13 RCT; 2 MA; >2,000 cycles Similar CPR, LBR, miscarriage True Vaginal P safer and more patient-friendly? 3 RCT; 1 MA; >2,000 cycles Lower side effects; Increased patient satisfaction True Among vaginal P, patients prefer gel? 7 RCT; 1 MA; >2,400 cycles Easier to use; better adherence; lower discharge True High-quality evidence on LPS Schoolcraft et al 2000; Yanushpolsky et al-2008; Zarutskie & Phillips Fertil Steril. 2009; Polyzos et al Fertil Steril 2010; van der Linden et al Cochrane 2011

  25. 25. Agents and routes of LPS Summary Comparable cycle outcomes among P preparations (Vaginal, IM, Oral), fresh and FET Vaginal P results in higher endometrial levels and is associated with fewer side effects than IM progesterone Similar pregnancy outcome with vaginal gel and all other vaginal P preparations (capsules, pressaries, tablets, ring) Patients prefer vaginal gel
  26. 26. Quality of LPS strategy can be measured… What is the most effective, safe and patient- centered LPS protocol we should apply? Agents and routes of administration Which dose and when to start and stop LPS
  27. 27. Dose of vaginal P No. studies No. OR 95% CI Live birth 2 1485 1.01 0.81-1.26 Clinical PR 12 4973 1.04 0.92-1.17 Miscarriage rate 8 2350 1.27 0.85-1.89 Multiple PR 4 905 0.95 0.57-1.58 Low dose Crinone 8% (90 mg) vs. high dose 200-800 mg/d; capsules, tablets, pressaries Similar outcome Van der Linden et al Cochrane 2011
  28. 28. When to start LPS Mochtar et al, 2009 RCT, N=385 LPS started either at day of hCG, OPU or ET day Similar outcome Mochtar MH. Hum Reprod. 2006;21:905-8. Outcome N (%) RR 95% CI Clinical PR OPU 36 (28.1) hCG 30 (23.1) 0.82 0.54- 1.24 ET 37 (29.1) 1.04 0.70- 1.53 Live birth OPU 27 (21.1) hCG 26 (20.0) 0.94 0.58- 1.52 ET 26 (20.5) 0.97 0.60- 1.56
  29. 29. Agents Early (pregnancy test) vs. late P cessation (6th-7th week) Early vs. late P cessation Early (pregnancy test or clinical pregnancy) vs. late P cessation (6th-7th week) When to stop LPS Liu et al. Reprod Biol Endocrinol. 2012; 10:107 Evidence Conclusion 2 RCT; 1 MA; >350 cycles No difference LBR 6 RCT; 1 MA; >1,000 cycles No difference miscarriage 8 RCT; 1 MA; >1,200 cycles No difference OPR
  30. 30. Prolonged progesterone use for preventing recurrent miscarriage (≥3 events) Haas DM, Ramsey PS. Progestogen for preventing miscarriage. Cochrane Database Syst Rev. 2013 Treatment for these women may be warranted given the reduced rates of miscarriage and the finding of no statistically significant difference between treatment and control groups in rates of adverse effects suffered by either mother or baby. • 3 trials; 225 patients
  31. 31. Which dose and when to start and stop P Summary Comparable cycle outcomes using low (90 mg/d) and high doses (>100 mg/d) vaginal P No difference when P is started at day of hCG, OCP or ET Evidence supports early cessation of LPS, but for patients with a history of recurrent miscarriage
  32. 32. Effectiveness Safety Patient- centeredness P alone ✔ ✔ Vaginal P gel ✔ ✔ 2-week regimen ✔ ✔

  34. 34. LPS SOP at Androfert* Progesterone gel (Crinone 8%) 90 mg daily Start at day 2 post-OCP Stop upon completion of 9-week gestation No serum determination of P or E2 Likely to bleed before progesterone discontinuation if not pregnant *hCG trigger
  35. 35. Bleeding before P discontinuation Consequence and not a cause of non-pregnant state Reflects the lack of a viable pregnancy rather than inadequacy of luteal support Distribution of the onset of menses following HCG (day 0) in non-pregnant women n = 63 Women who bled before discontinuing P supplementation likely to have low levels of estradiol Roman E et al. Hum Reprod. 2000
