Oral dydrogesterone

We conducted a double-blind, randomized, placebo-controlled clinical trial to evaluate the efficacy of oral dydrogesterone (DG) on maternal and neonatal consequences in the treatment of preterm labor. We included 100 nulliparous mothers (24-34 weeks) with normal pregnancy who had preterm labor pain. Participants who received magnesium sulfate were randomly assigned to the investigation group (DG 30 mg/day) or placebo group. Maternal and neonatal outcomes were compared between the two groups. Recurrent uterine contraction (UC) rates (92% vs...

The aim of this systematic review was to evaluate the efficacy of oral medication or intrauterine device-delivered progestins in patients with endometrial hyperplasia (EH) with or without atypia. We systematically examined PubMed, EMBASE, the Cochrane Library, and clinicaltrials.gov to identify studies reporting the regression rate of patients with EH who received progestins or non-progestins. The regression rates after different treatments were compared using a network meta-analysis in terms of the relative ratios (RRs) and 95% confidence intervals (CIs)...

RESEARCH QUESTION: Does additional supplementation with oral dydrogesterone improve reproductive outcomes in patients with low serum progesterone concentrations on the day of frozen embryo transfer (FET) after artificial (HRT) endometrial preparation? DESIGN: Retrospective, single-centre cohort study including 694 unique patients performing single blastocyst transfer in an HRT cycle. For luteal phase support, intravaginal micronized vaginal progesterone (MVP, 400 mg twice daily) was administered...

INTRODUCTION: The number of frozen embryo transfers increased substantially in recent years. To increase the chances of implantation, endometrial receptivity and embryo competency must be synchronized. Maturation of the endometrium is facilitated by sequential administration of estrogens, followed by administration of progesterone prior to embryo transfer. The use of progesterone is crucial for pregnancy outcomes. This study compares the reproductive outcomes and tolerability of five different regimens of hormonal luteal phase support in artificial frozen embryo transfer cycles, with the objective of determining the best progesterone luteal phase support in this context...

OBJECTIVE: To evaluate the effects of dydrogesterone treatment on first-trimester aneuploidy screening markers and nuchal translucency (NT) in women with threatened miscarriage. MATERIALS AND METHODS: This study is an prospective case-control study. One hundred seven pregnant women who applied for the first-trimester screening test at 11-14th weeks of gestation were included in the study. The study group consisted of 53 pregnant women using oral dydrogesterone due to the threat of miscarriage for at least 2 weeks and without vaginal bleeding for the last 72 h at the time of enrollment...

This study aimed to evaluate the pregnancy rates, adverse reactions, and medication costs of two luteal phase support regimens: oral dydrogesterone and micronized vaginal progesterone (MVP) pessary in in vitro fertilization cycles. A randomized open-label trial with participants randomly assigned to either 400 mg MVP twice daily or 10 mg dydrogesterone three times daily. The primary endpoints were pregnancy rates, and the secondary endpoints included tolerance, miscarriage rates, and medication cost. Per-protocol principle analysis was performed...

OBJECTIVE: Intervertebral discs act as shock absorbers, thereby helping to reduce the risk of vertebral body fractures. Previous studies have shown that estrogen loss following menopause is associated with disc height reduction whereas treatment with hormone replacement therapy (HRT) helps to maintain disc height. This study reports the effect of HRT on disc height from a post hoc analysis of a prospective randomized clinical trial of the effect of HRT on bone density. METHODS: A total of 355 healthy postmenopausal women aged (mean ± standard deviation) 55...

IMPORTANCE: The necessity of progesterone supplementation for luteal phase support (LPS) in natural cycle frozen embryo transfer (NC-FET) cycles warrants further confirmation. OBJECTIVE: To investigate the effect of progesterone supplementation for LPS on the reproductive outcomes of patients undergoing NC-FET cycles. DATA SOURCES: The PubMed, Ovid-Embase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP, and CBM were electronically searched...

INTRODUCTION: Low serum progesterone concentration on frozen embryo transfer (FET) day in hormone replacement therapy (HRT) cycles results in lower reproductive outcomes. Recent studies showed the efficiency of a "rescue protocol'' to restore reproductive outcomes in these patients. Here, we compared reproductive outcomes in HRT FET cycles in women with low serum progesterone levels who received individualized luteal phase support (iLPS) and in women with adequate serum progesterone levels who underwent in vitro fertilization for pre-implantation genetic testing for structural rearrangements or monogenic disorders...

Background: Pharmacotherapy is one of the primary treatments for patients with Assisted reproductive technology (ART). Despite the publication of various research on ART treatment, there is no clear conclusion regarding the choice of drug treatment in China. Our research intends to examine the trend of widely prescribed medications for ART patients in China. For instance, the study examines the logic of drug indications, usage, and dose in patient prescriptions. Methods: We did a cross-sectional study of the data from the hospital prescription analysis cooperation project supervised by the China Medical Association...

BACKGROUND: Premature ovarian insufficiency (POI) is a clinical syndrome resulting from loss of ovarian function before the age of 40. It is a state of hypergonadotropic hypogonadism, characterised by amenorrhoea or oligomenorrhoea, with low ovarian sex hormones (oestrogen deficiency) and elevated pituitary gonadotrophins. POI with primary amenorrhoea may occur as a result of chromosomal and genetic abnormalities, such as Turner syndrome, Fragile X, or autosomal gene defects; secondary amenorrhoea may be iatrogenic after the surgical removal of the ovaries, radiotherapy, or chemotherapy...

RESEARCH QUESTION: What should be the optimal route of luteal support in programmed frozen embryo transfer (FET) cycles? DESIGN: This was a randomized, parallel, phase IV pilot trial with three groups of women undergoing FET along with hormone replacement therapy for endometrial preparation at a tertiary private IVF centre (NCT03948022). Women with at least one autologous cryopreserved blastocyst were included. After preparing the endometrium with oestradiol, 151 women were randomly assigned to one of the following three progesterone arms before embryo transfer: oral (10 mg) dydrogesterone (DYD), total daily dose 40 mg (n = 52); 8% (90 mg) progesterone vaginal gel (VAG), total daily dose 180 mg (n = 55); or intramuscular progesterone (IMP) 50 mg/ml in oil, total daily dose 100 mg (n = 44)...

Introduction: One of the hormones that are crucial in safe pregnancy is the Progesterone. Its defect may cause bleeding and abortion. Hence, in this study, we evaluated two different drug modalities of progesterone for their efficacy. Material and Methods: We piloted a prospective observational study among 100 pregnant women in their first trimester. They were divided to two equal groups to receive oral dydrogesterone and vaginal progesterone. The clinical and the demographic data with detailed history were taken and noted...

RESEARCH QUESTION: Do differences exist in euploidy rates in preimplantation genetic testing for aneuploidy (PGT-A) cycles with oral dydrogesterone primed ovarian stimulation protocol or the flexible gonadotropin-releasing hormone (GnRH) antagonist protocol? DESIGN: A retrospective cohort study. Patients received the oral dydrogesterone or the GnRH antagonist in the first PGT-A cycle between November 2017 and May 2019. Propensity matching was used to identify a propensity-matched antagonist group based on age, BMI and AMH with a 1:1 ratio...

AIM: The aim of these recommendations is to set forth an individualized approach to the management of early postmenopausal women (i.e., within the first 10 years after natural menopause) covering all aspects of lifestyle and therapeutic management, with or without menopause hormone therapy (MHT). MATERIALS AND METHODS: Literature review and consensus of French expert opinion. Recommendations were graded according to the HAS methodology and levels of evidence derived from the international literature, except when there was no good-quality evidence...

OBJECTIVES: Progesterone, a sex steroid, is measured in serum by immunoassay in a variety of clinical contexts. One potential limitation of steroid hormone immunoassays is interference caused by compounds with structural similarity to the target steroid of the assay. Dydrogesterone (DYD), an orally active stereoisomer of progesterone, is used for various indications in women's health. Herein, we report a systematic in vitro investigation of potential interference of DYD and its active metabolite 20α-dihydrodydrogesterone (DHD) in seven widely used, commercially available progesterone assays...

STUDY QUESTION: What are the plasma concentrations of dydrogesterone (DYD) and its metabolite, 20α-dihydrodydrogesterone (DHD), measured on day of embryo transfer (ET) in programmed anovulatory frozen embryo transfer (FET) cycles using 10 mg per os ter-in-die (tid) oral DYD, and what is the association of DYD and DHD levels with ongoing pregnancy rate? SUMMARY ANSWER: DYD and DHD plasma levels reach steady state by Day 3 of intake, are strongly correlated and vary considerably between and within individual subjects, women in the lowest quarter of DYD or DHD levels on day of FET have a reduced chance of an ongoing pregnancy...

OBJECTIVES: The objective of the study was to compare the live birth rate and miscarriage rate after fresh embryo transfer (Fresh ET) when patients are treated either with oral dydrogesterone or micronized vaginal progesterone (MVP) as luteal phase support (LPS). The vaginal route is still preferred, despite the discomfort for the patients and recent RCTs showing similar results for dydrogesterone and MVP. METHODS: All 556 consecutive Fresh ET after autologous IVF procedure, from December 2011 to March 2013 in one centre in France were included...

OBJECTIVE: The aim of this study was to compare the use of micronized vaginal progesterone and oral dydrogesterone in the endometrial preparation for frozen-thawed embryo transfer. METHODS: This was a randomized, controlled, open, two-armed clinical trial, with women undergoing frozen-thawed embryo transfer along with hormone replacement therapy for endometrial preparation, between September 2019 and February 2021. A total of 73 patients were randomly selected and orally administered 40 mg/day dydrogesterone (dydrogesterone group, n=36) or 800 mg/day micronized vaginal progesterone (micronized vaginal progesterone group, n=37), after endometrial preparation with transdermal estradiol...
