Research questionIn patients in whom endometrial polyps are diagnosed during ovarian stimulation for IVF, are there differences in reproductive outcomes in women continuing to undergo fresh embryo transfer, and those in whom embryos are cry…

The study investigates whether a 3-day pretreatment course with a GnRH antagonist in the early follicular phase has an impact on the number of retrieved COCs in a GnRH antagonist stimulation protocol. This is a retrospective single center c…

Research questionDoes a frozen-embryo transfer in an artificially-prepared endometrium (FET-HRT) cycle yield similar clinical pregnancy rate with 7 days of oestrogen priming compared to 14 days?DesignThis is a single-centre, randomized, con…

A high ovarian response to conventional ovarian stimulation (OS) is characterized by an increased number of follicles and/or oocytes compared with a normal response (10-15 oocytes retrieved). According to current definitions, a high respons…

PurposeDoes cell loss (CL) after vitrification and warming (V/W) of day 3 embryos have an impact on live birth rate (LBR) and neonatal outcomes?MethodThis retrospective analysis includes cleavage stage day 3 embryos vitrified/warmed between…

The prolonged lockdown of health services providing high-complexity fertility treatments -as currently recommended by many reproductive medicine entities- is detrimental for society as a whole, and infertility patients in particular. Global…

OBJECTIVE: To determine the relationship between steroid receptor expression and pain symptoms in endometriosis. DESIGN: Cross-sectional SETTING: University Hospital PATIENT(S): Women with endometriosis (N = 92). INTERVENTION(S): Tissue s…

Despite the considerate progress to which assisted reproduction technology (ART) has been subject since 1978, some issues remain unresolved. Notably, the clinical management of patients with a poor ovarian response is still a challenge in e…

PurposeTo evaluate whether ICSI offers any benefit compared with IVF in different ovarian response categories in case of non-male factor infertility.MethodsThis is a retrospective multicenter analysis using individual patient data, conducte…

Research Question: What is the effect of gonadotropin-releasing hormone (GnRH)-agonist treatment on serum anti-Müllerian hormone (AMH)? Design: This prospective cohort study conducted in a tertiary university hospital comprised patients (n …

Since the introduction of gonadotropin-releasing hormone (GnRH) antagonists, an extensive amount of literature investigating the role of the downregulation protocols on pregnancy outcomes has been published. However, these studies were main…

Several infertile patients, who may even represent around 40% of the infertile cohort, may respond "suboptimally" (4-9 oocytes retrieved) following IVF, despite being predicted as normal responders. The aim of our longitudinal study was to …

STUDY QUESTION: What is the effect of vitamin D deficiency on the pregnancy rates following frozen embryo transfer (FET)?. SUMMARY ANSWER: Vitamin D deficiency does not affect pregnancy rates in FET cycles. WHAT IS KNOWN ALREADY: Although t…

A 34-year-old woman without any medical history presented to our hospital emergency unit with a history of 4 days of progressively increasing pain in the left iliac fossa, fever and vaginal bleeding for the past 3 weeks. Urine pregnancy tes…

Endocrine disorders play a major role in approximately 8% to 12% of recurrent pregnancy loss (RPL). Indeed, the local hormonal milieu is crucial in both embryo attachment and early pregnancy. Endocrine abnormalities, including thyroid disor…

Endocrine disorders contribute to the pathology of approximately 8% to 12% of recurrent pregnancy losses. Because embryo attachment and early implantation are controlled by the local hormonal milieu, endocrine-related pregnancy failures are…

IntroductionRobotic single-site surgery (RSS) represents the latest innovation for clinical use of single incision surgery. Several applications have been reported in urology, general surgery and gynecology with potential application in ben…
