REVIEW
Georg Griesinger, Christophe Blockeel, Herman Tournaye
Oral dydrogesterone has been used for luteal phase support on an empirical basis since the early days of in vitro fertilization (IVF) treatment. Systematic comparisons of oral dydrogesterone with vaginal progesterone, so far considered to be the standard of care, started to appear in the middle 2000s. Recently, a large, randomized, double-blind, double-dummy phase III trial on the use of daily 30 mg oral dydrogesterone versus daily 600 mg micronized vaginal progesterone for LPS in IVF was published. This company-sponsored trial confirmed the efficacy findings from previous independent researchers and firmly established the noninferiority of daily 30 mg oral dydrogesterone for luteal phase support...

REVIEW

Luteal phase support is mandatory in ovarian stimulation cycles in assisted reproductive technology owing to a deficit in LH pulsatility after the effects of exogenous hCG-used for triggering ovulation-vanish. This is classically accomplished by means of exogenous P administration, but emerging new options include microdoses of hCG and exogenous GnRH agonist. Although luteal phase support is commonly continued for up to 10 weeks into pregnancy, there is accumulating evidence that it can be stopped after the first ultrasound or even after a positive pregnancy test...

BACKGROUND: Although not guideline recommended, studies suggest 50% of locoregional breast cancer patients undergo systemic imaging during follow-up, prompting its inclusion as a Choosing Wisely measure of potential overuse. Most studies rely on administrative data that cannot delineate scan intent (prompted by signs/symptoms vs. asymptomatic surveillance). This is a critical gap as intent is the only way to distinguish overuse from appropriate care. OBJECTIVE: Our aim was to assess surveillance systemic imaging post-breast cancer treatment in a national sample accounting for scan intent...

Clinical and animal model studies have demonstrated the neuroprotective and anti-inflammatory effects of 17beta-estradiol (E2) and progesterone (P) in different disease models of the central nervous system (CNS) including ischemic stroke. Inflammasomes are involved in the interleukin-1 beta (IL1beta) maturation, in particular, NLRP3, the adaptor protein apoptosis-associated speck-like protein containing a CARD (ASC) and the active caspase-1 (Casp1) form. Recently, we showed that administration of E2 or P selectively regulated these components after experimental ischemic stroke in rats...

Different dietary ratios of n -6/ n -3 long-chain polyunsaturated fatty acids (LC-PUFAs) may alter brain lipid profile, neural activity, and brain cognitive function. To determine whether ovarian hormones influence the effect of diet on the brain, ovariectomized and sham-operated mice continuously treated with placebo or estradiol were fed for 3 months with diets containing low or high n -6/ n -3 LC-PUFA ratios. The fatty acid (FA) profile and expression of key neuronal proteins were analyzed in the cerebral cortex, with intact female mice on standard diet serving as internal controls of brain lipidome composition...

Intrauterine inflammation causes preterm birth and is associated with complications in preterm neonates. Thus, strategies aimed at suppressing inflammation are expected to be effective for reducing the risk of preterm birth and associated complications. Our previous studies demonstrated that molecular hydrogen (H2 ), an anti-inflammatory agent, prevented inflammation-induced impairment in foetal brain and lung tissues in lipopolysaccharide (LPS)-induced rodent models. However, it remains unclear whether H2 is capable of inhibiting preterm labour...

Decidual protein induced by progesterone (DEPP/DEPP1/C10ORF10) is induced by denying access to food and reduced by refeeding in insulin-sensitive organs in vivo. The negative regulation of DEPP by insulin is also proven in several cell lines. However, the functions of DEPP in insulin-sensitive organs remain unknown. In the present study, we investigated the impact of DEPP on hepatic energy metabolism and addressed the underlying mechanisms. The metabolic effects of DEPP were investigated in mice with adenovirus-mediated hepatic overexpression...

It remains unclear how rapidly progesterone suppresses luteinizing hormone (LH) pulse frequency in women. Previous studies suggested that progesterone markedly increases LH pulse amplitude but does not slow LH pulse frequency within 10 h in estradiol-pretreated women studied during the late follicular phase. However, this experimental paradigm may be a model of preovulatory physiology, and progesterone may have different effects at other times of the cycle. We studied regularly cycling, nonobese women without hyperandrogenism to assess the acute effect of progesterone during the midfollicular phase and in the absence of estradiol pretreatment...
