    • ...in all age groups Esteves, 6 ANDROFERT, Referral Center for Male Reproduction
    • Gonadotropin Preparations and Oocyte Yield Esteves, 7 ANDROFERT, Referral Center for Male Reproduction
    • Evidence Level 1b RCT and meta-analyses comparing oocyte yield with different gonadotropins ↑ 1.5 oocytes (GnRH antagonist cycles) Devroey et al., 2012 No. Oocytes retrieved higher with Rec-FSH vs. hMG, HP-hMG, and uFSH ↑ 2.1 oocytes (16 RCT; different protocols) Lehert et al., 2010 ↑ 3.1 oocytes (GnRH antagonist cycles) Bosch et al., 2008 ↑ 2.8 oocytes (GnRH agonist cycles) Hompes et al., 2008 ↑ 1.8 oocytes (GnRH agonist cycles) MERIT Study, 2006 Esteves, 8 ANDROFERT, Referral Center for Male Reproduction
    • It relates to the way the drug is made, filled and delivered Protein content in solution by mass (FbM) in rec-FSH Protein content hMG hMG-HP Specific activity (IU/mg protein) Injected protein per 75 IU (mcg) < 5% ~100 ~750 < 70% 2,000–2,500 ~33 13,645 Size Exclusion High Performance Liquid Chromatography (SE- HPLC) 6.1 rec-hFSH* > 99% *Follitropin alfa; Bassett et al.

    • Quantity vs. Quality which one come first? • Oocyte/embryo quality? • Endometrial receptivity? Esteves, 10 ANDROFERT, Referral Center for Male Reproduction
    • Morphology-based embryo quality and number of oocytes Embryo quality score Implantation rate (%) A large oocyte 1,301 cycles 23 cohort was the 17 main factor that increased the 3,8 4,5 chance of having at least one good 1-6 oocytes embryo 7-15 oocytes 27 p<0.001 4,8 >15 oocytes Devreker et al Hum Reprod 1999 Esteves, 11 ANDROFERT, Referral Center for Male Reproduction
    • Aneuploidy and Oocyte Yield Aneuploidy rate % 60 634 patients; 3,688 oocytes; PB biopsy 50 <35 years 40 35-40 years >40 years 30 20 10 0 p<0.001 The higher the oocyte cohort, the higher the number of EUPLOID oocytes in all age groups 1-5 oocytes 6-10 oocytes >10 oocytes Haaf et al Fertil Steril 2009 Esteves, 12 ANDROFERT, Referral Center for Male Reproduction
    • Aneuploidy and Oocyte Yield • Array CGH analysis in D3 and D5 embryos • 7753 embryos from 990 patients • Linear regression analysis adjusted by maternal age Higher aneuploidy rate in older women irrespective of embryo number Higher number of euploid embryos with increased cohort size Ata et al Reprod Biomed Online. 2012 Esteves, 13 ANDROFERT, Referral Center for Male Reproduction
    • What we have learned There is a strong association between the number of oocytes retrieved and live birth rates in IVF The optimum number of oocytes needed to maximize IVF outcomes seems to be about 15 Recombinant gonadotropin preparations are more potent and result in an increased oocyte yield Esteves, 14 ANDROFERT, Referral Center for Male Reproduction
    • What we have learned Aneuploidy in oocytes increases with maternal age, but it is unaffected by cohort size in women aged 35 or older Among young women, an increased incidence of aneuploid oocytes seems to be associated with higher oocyte cohort The higher the cohort size, the higher the number of euploid oocytes and embryos regardless of age Esteves, 15 ANDROFERT, Referral Center for Male Reproduction
    • How to get the best results oocyte quality vs. quantity Increasing oocyte yield is an opportunity to have more euploid embryos The goal is to obtain ~15 oocytes avoiding OHSS COS should be tailored to the individual phenotype, maximizing the number of oocyte yield for poor responders and fine-tuning for hyper-responders Esteves, 16 ANDROFERT, Referral Center for Male Reproduction
    • More is good, but does it affect implantation? • Oocyte/embryo quality? • Endometrial receptivity? Esteves, 17 ANDROFERT, Referral Center for Male Reproduction
    • Effect of progesterone levels on pregnancy in IVF – Do they matter? Fresh Frozen-thawed Donor/recipient P ng/mL 63 studies; N = 55,199 9 studies; N =7,229 8 studies; N = 1,330 LBR/OPR CPR CPR 0.8-1.1 OR: 0.72 OR: 1.18 (0.76 – 1.84) OR: 0.64 OR: 1.03 (0.79 – 1.34) OR: 0.83 (0.62 – 1.32) (0.64 – 4.05) OR: 0.62 (0.57 – 0.69) OR: 1.13 (0.97 – 0.69) - OR: 0.67 OR: 1.03 OR: 0.51 (0.55 – 0.81) (0.84 – 1.27) (0.12 – 2.19) 1.2-1.4 1.5-1.75 1.9-3.0 (0.56 – 0.94) (0.53 – 0.77) OR: 1.61 P levels not related to oocyte and embryo quality, nor with fertilization and cleavage rates Venetis et al., Hum Reprod Update 2013 Esteves, 18 ANDROFERT, Referral Center for Male Reproduction
    • Progesterone levels in stimulated cycles Number of oocytes Estradiol levels FSH dose Rec-hFSH vs. hMG positively associated with P levels Bosch et al. 2008, 2010; Xu et al, 2012; Kolibianakis et al 2012; Venetis et al. 2012; Griesinger et al 2013 Esteves, 19 ANDROFERT, Referral Center for Male Reproduction
    • No CYP17 LH Esteves, 20 FSH LH
    • hMG Grondal et al. 2009: r-FSH P levels with rec-hFSH and hMG GCs gene expression in pts. treated with hMG and rec-hFSH  Lower expression of LH/hCG receptor gene and other genes involved in steroids biosynthesis with hMG Down-regulation of receptors owed to constant ligand exposure to hCG (Menon et al. 2004) CYP11A activity decreased by 2.4-fold Lower steroids synthesis and P levels  Higher potency of rec-hFSH inducing more LH/hCG receptors Esteves, 21 Grondal ML et al. Fertil Steril 2009; 91: 1820-1830. Menon KM et al. Biol Reprod 2004; 70:861-866
    • What we know about progesterone levels in stimulated cycles Most circulating Progesterone (95%) is produced in the intrafollicular compartment by granulosa cells Higher serum P are related to more follicles developed (more GCs) and more oocytes retrieved Treatment with rec-hFSH results in higher P levels than hMG Rec-hFSH has higher FSH bioactivity (increased GCs and oocyte yield HMG induces underexpression of genes involved in steroids synthesis Bosch et al,. Hum Reprod. 2008 ;23(10):2346-51; Grøndahl ML, et al. Fertil Steril 2009; 91(5): 1820-30. Esteves, 22 ANDROFERT, Referral Center for Male Reproduction
    • Progesterone levels and pregnancy Bosch et al. 2010 (N=4,032) Irrespective of GnRH analogue; Cut-off = 1.5 ng/mL Xu et al, 2012 (N=11,055) GnRH agonist Ovarian response Number of oocytes Serum P threshold (ng/mL) Poor ≤4 1.5 Intermediate 5-19 1.75 High ≥20 ■ Fresh ■ FET 2.25 Esteves, 23 ANDROFERT, Referral Center for Male Reproduction
    • Do we need to measure P levels at hCG day in stimulated cycles? How often P4 rise: Overall: 8.4% Low-responder: 4.5% High-responder: 19% 6 RCT, N=1866; Antagonist cycles OPR not impaired in high responders with P elevation Ongoing PR: OR = 0.55 (0.37–0.81) Griesinger et al. Fertil Steril 2013 Esteves, 24 ANDROFERT, Referral Center for Male Reproduction
    • Effects of progesterone levels at hCG day on pregnancy Intrafollicular P4 is a terminal product. It cannot be converted to estradiol by GCs under the effect of gonadotropins containing hCG. The expression of CYP17 needed for this pathway is negligible Conflicting data on what levels Progesterone is detrimental to implantation in fresh transfers. P levels not so critical in women with high oocyte yield Adequate number of embryos for freezing and FET is an opportunity to overcome any detrimental effect of P4 on the endometrium Wickenheisser et al. Trends Endocrinol Metab. 2006; 17(2): 65-71; Nguyen PT et al. J Theor Biol. 2013; 332: 52-64. Esteves, 25 ANDROFERT, Referral Center for Male Reproduction

    • Cumulative pregnancy rate as a strategy to improve success in IVF The most important endpoint for the patient Allow estimation of likelihood of delivery in relation to no. oocytes/embryos obtained and prognostic factors such as age Esteves, 34 ANDROFERT, Referral Center for Male Reproduction
    • Conclusions (1) The number of oocytes retrieved is a key factor for optimizing live birth rates COS should be tailored to the individual phenotype, maximizing the number of oocyte yield for poor responders and fine-tuning for hyper-responders Among gonadotropin preparations, recombinant FSH gives the highest oocyte yield Higher FSH bioactivity, which is related to the way the drug is made, filled and delivered Esteves, 35 ANDROFERT, Referral Center for Male Reproduction
    • Conclusions (2) Progesterone levels on hCG day are related to number of follicles developed (GCs) and oocytes retrieved No conclusive data on P levels detrimental to implantation in fresh transfers Progesterone cannot be converted to estradiol under the effect of gonadotropins containing LH activity Adequate number of viable embryos for freezing and FET can overcome any detrimental effect of P on the endometrium Esteves, 36 ANDROFERT, Referral Center for Male Reproduction
