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)

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)
Adapted from Jones‐1996 by Fauser and Devroey‐2003
• COS per se constitutes anindication for luteal phase support

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?

Multiple (duplicate) publication bias Themultiple or singular publication of research findings, depending on the nature and direction of the results
Location bias 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.
Citation bias The citation or non‐citation of research findings, depending on the nature and direction of the results
Language bias The publication of research findings in a particular language, depending on the nature and direction of the results
Outcome reporting bias The selective reporting of some outcomes but not others, depending on the nature and direction of the results

• 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
When to stop LPS?
Day of positive ‐hCG Day fetal heartbeat Week 8‐10‐12
All have similar ongoing pregnancy rates

Progesterone for luteal support: the oral route
Micronization: improved absorption of oral P
Poor bioavailability
Circulating levels are too low for adequate support
Liver first pass leads to massive metabolism
At best 10% circulates as active P
Inadequate secretory transformation
Dose increase: unacceptable somnolence

Oral dydrogesterone for luteal phase support in IVFAn oral retroprogesterone – progesterone agonistApproved 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

• 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

• Water insolubility of P: an aqueous preparation of P was seemingly impossible
• Enhancing polarity by encapsulation of P molecules in a starch residue, cyclodextrine
• On reaching bodily fluids, cyclodextrine is readily digested
• This liberates native P, which reaches the general circulation
• Prolutex—is available in single‐use preparations
• Contains no preservatives
