RESEARCH QUESTION: How can outcomes in programmed frozen embryo transfers (FET) be improved, and what are the key areas where more research is needed? DESIGN: Using a Delphi-consensus framework, a scientific committee comprising five exper…

Diminished ovarian reserve (DOR) is common in women with infertility and is associated with poorer in vitro fertilization (IVF) outcomes. Testosterone is widely used off-label in this patient group, although evidence for its efficacy and sa…

Studies have suggested transferring Day 6 (D6) vitrified blastocyst in a frozen embryo transfer (FET) cycle. This study investigates whether D6 blastocysts should be transferred on the 5th or 6th day of progesterone administration during a …

The primary aim of the present randomised, double-blind, placebo-controlled trial was to investigate whether clindamycin and live Lactobacillus crispatus CTV-05 (LACTIN-V) would improve clinical pregnancy rates in IVF patients with abnormal…

PURPOSE: Alongside being contraceptives, progestins have been investigated as potential anti-inflammatory and analgesic therapies for use in painful gynaecological conditions. This review aims to synthesise evidence pertaining to the effica…

Adenomyosis is an important clinical condition with uncertain prevalence, and clinical focus on adenomyosis in patients undergoing assisted reproductive technology (ART) has increased during recent years. Recognizing the limited clinical kn…

PurposeTo investigate baseline parameters and vaginal intimate hygiene habits comparing IVF patients with and without vaginal dysbiosis, a cross-sectional study.MethodsPatients were grouped by the presence of vaginal dysbiosis status determ…

BackgroundIn a global effort to assess expert perspectives on the use of recombinant gonadotropins, recombinant human luteinizing hormone (r-hLH) and recombinant human follicle-stimulating hormone (r-hFSH), a consensus meeting was held in D…

Abstract Study question Does subcutaneous (SC) progesterone treatment provide progesterone levels comparable to intramuscular (IM) progesterone when using a cut-off level of 118nmol/l(37.1ng/ml) during intensive luteal phase support? Summar…

Endometriosis and adenomyosis are distinct clinical conditions that carry the same pathophysiological features. In recent years the clinical focus on assisted reproductive technology patients with either condition (E/A) has increased, in th…

BackgroundSpecific polymorphisms might influence controlled ovarian stimulation in women undergoing assisted reproductive technologies (ARTs). Data regarding possible interactions of these polymorphisms are still scanty. The aim of this ana…

Study questionCan supplementation with rectal administration of progesterone secure high ongoing pregnancy rates (OPRs) in patients with low serum progesterone (P4) on the day of blastocyst transfer (ET)?Summary answerRectally administered …

BackgroundIn a true-natural cycle (t-NC), optimal progesterone (P4) output from the corpus luteum is crucial for establishing and maintaining an intrauterine pregnancy. In a previous retrospective study, low P4 levels (< 10 ng/mL) measured …

RESEARCH QUESTION: What is the optimal serum progesterone cut-off level in patients with endometriosis undergoing hormone replacement therapy frozen embryo transfer (HRT-FET) with intensive progesterone luteal phase support? DESIGN: A coho…

Abstract Study question What is the optimal serum progesterone (P4) cut-off level for endometriosis patients undergoing hormone replacement therapy frozen embryo transfer (HRT-FET) with intensive exogenous progesterone luteal phase support?…

Despite the worldwide increase in frozen embryo transfer, the search for the best protocol to prime endometrium continues. Well-designed trials comparing various frozen embryo transfer protocols in terms of live birth rates, maternal, obste…

Luteinizing hormone (LH) and follicle-stimulating hormone (FSH) play complementary roles in follicle development and ovulation via a complex interaction in the hypothalamus, anterior pituitary gland, reproductive organs, and oocytes. Impair…

OBJECTIVE: The objective of this retrospective cohort study was to explore the optimal range of the total progressive motile sperm count (TPMSC) for live birth in couples with varying infertility diagnosis undergoing intrauterine inseminati…

IntroductionRecent studies in in vitro fertilisation (IVF) patients have associated abnormal vaginal microbiota (AVM) with poor clinical pregnancy rates of 6%-9% per embryo transfer. The biological plausibility for this finding is hypothesi…

ObjectiveTo compare the ongoing pregnancy rate between a freeze-all strategy and a fresh transfer strategy in assisted reproductive technology treatment.DesignMulticentre, randomised controlled superiority trial.SettingOutpatient fertility …

ObjectiveThe aim was to investigate the association between clinically significant uterine fibroids and preterm birth, caesarean section (CS), postpartum haemorrhage (PPH), placental abruption, intrauterine growth restriction (IUGR) and ute…

Research question: Urine LH testing may be useful to confirm an LH surge after the GnRH agonist (GnRHa) trigger prior to oocyte retrieval in IVF. Design: A prospective cohort study, including oocyte donors undergoing ovarian stimulation, tr…

Societal changes and the increasing desire and opportunity to preserve fertility have increased the demand for effective assisted reproductive technologies (ART) and have increased the range of scenarios in which ART is now used. In recent …
