A survey on luteal phase support:

Transcription

1 A survey on luteal phase support: An IVF Worldwide Survey results I have no conflict of interest!

2 The reason why luteal phase support is needed: The normal physiological support of the corpus luteum the pulsatile secretion of LH by the anterior pituitary is disrupted during controlled ovarian stimulation Mid luteal LH levels ~ 6.0 IU/l in natural cycle (Tavaniotou and Devroey 2003) ~ 1.5 IU/l GnRHa trigger (Humaidan et al. 2005) ~ 0.2 IU/l HCG trigger (Humaidan et al. 2005)

3 The luteal phase after COS Supraphysiological steroid level of E2 and P in early mid luteal phase exerts a negative feed back on the hypothalamic pituitary axis reducing LH secretion in early luteal phase. (Tavaniotou and Devroey, 2006; Tavaniotou et al., 2001) COS per se constitutes an indication for luteal phase support Adapted from Jones 1996 by Fauser and Devroey 2003

4 Pharmacokinetics of hcg administration Weissman et al., Gynecol Endocrinol 10; 273 6: 1996.

6 Luteal phase support in ART Formulation and route of administration When to start? When to stop? What should be included? Should LPS in ART be individualized?

8 Type of reporting bias Publication bias Time lag bias Multiple (duplicate) publication bias Location bias Citation bias Language bias Outcome reporting bias Definition The publication or non publication of research findings, depending on the nature and direction of the results The rapid or delayed publication of research findings, depending on the nature and direction of the results The multiple or singular publication of research findings, depending on the nature and direction of the results The publication of research findings in journals with different ease of access or levels of indexing in standard databases, depending on the nature and direction of results. The citation or non citation of research findings, depending on the nature and direction of the results The publication of research findings in a particular language, depending on the nature and direction of the results The selective reporting of some outcomes but not others, depending on the nature and direction of the results Jonathan AC Sterne, Matthias Egger and David Moher on behalf of the Cochrane Bias Methods Group, 2011.

18 % In most cases, how do you determine which luteal support regimen to use for your patients?

19 If you support the luteal phase, when do you start the regimen you use? At the time of hcg admin. At the time OPU One day post OPU At the time of ET 6 days post OPU

26 When to start LPS? Day of OPU Day after OPU Day of ET All equally effective Initiating LPS on the day of or day after oocyte retrieval, has now become a routine practice in ART

33 Miscarriage rate

34 When to stop LPS? Day of positive hcg Day fetal heartbeat Week All have similar ongoing pregnancy rates On the day of the positive hcg the CL is supported by hcg of embryonic origin Clinical data now confirm this view This should encourage treatment teams to discontinue LPS on the day of positive hcg

44 Oral Micronized Progesterone

48 Oral dydrogesterone

49 Oral dydrogesterone for luteal phase support in IVF An oral retroprogesterone progesterone agonist Approved for: Threatened and recurrent miscarriage (associated with proven progesterone deficiency) Infertility due to luteal phase insufficiency It has been extensively used for a variety of indications since 1960 Compared with progesterone: Greater affinity for the progesterone receptors Can be used at lower oral doses to promote endometrial proliferation owing to its better bioavailability and to the progestogenic activity of its metabolites Schindler AE et al., Maturitas 2008;61:

54 Noninferiority of daily 30 mg oral dydrogesterone for luteal phase support Well tolerated as vaginal progesterone in safety analyses No new fetal safety concerns Widespread preference of women for an oral compound Dydrogesterone may well become the new standard for LPS in fresh IVF ET cycles

55 IM Progesterone

56 Progesterone for luteal support: The intramuscular route P is highly water insoluble P in oil Standard route of P delivery High efficiency: avoids hepatic first pass Several drawbacks: *Painful and uncomfortable * Preservatives (benzyl alcohol) *Sterile abscess formation *Allergic response *Time and cost

57 Progesterone for luteal support: The intramuscular route IM dosing: mg daily Long acting formulations Mean production rate of progesterone of 25 mg/24 h Gold standard of LPS in phase endometrial architecture Satisfactory pregnancy/miscarriage rates Able to delay menses in most women
