WHAT IS KNOWN ALREADYOocyte vitrification is performed routinely and successfully in IVF oocyte donation programs.
A retrospective cohort study was performed to examine whether, in artificial endometrial preparation for frozen embryo transfer (FET) cycles, progesterone (P) levels the day prior of euploid embryos have an impact on pregnancy outcomes. In a private university clinic, 244 FETs between January 2016 and June 2017 were analyzed. Endometrial achieved with estradiol valerate vaginal micronized progesterone. Serum P measured. multivariable analysis assess relationship serum level outcomes...
Abstract STUDY QUESTION Does an individualised luteal phase support (iLPS), according to serum progesterone (P4) level the day prior euploid frozen embryo transfer (FET), improve pregnancy outcomes when started on previous transfer? SUMMARY ANSWER Patients with low P4 FET can benefit from addition of daily subcutaneous injections (Psc), FET, and achieve similar reproductive compared those initial adequate levels. WHAT IS KNOWN ALREADY The ratio between FET/IVF has spectacularly increased in...
Between October 1998 and January 1999, we examined the influence of ultrasound guidance in embryo transfer on pregnancy rate 362 patients from our in-vitro fertilization (IVF)–embryo programme. These were prospectively randomized into two groups: 182 had ultrasound-guided replacement, 180 clinical touch transfer. There no statistically significant differences between groups with respect to age, cause infertility characteristics IVF cycle. The was significantly higher among group (50%)...
BACKGROUND: High-order multiple pregnancies (triplets or more) have a large adverse impact on perinatal morbidity and mortality as well important economic consequences. Most triplets higher births are due to ovulation induction alone in combination with intrauterine insemination (IUI) rather than in-vitro fertilization (IVF). The present investigation was undertaken determine whether there were specific variables that related patient clinical characteristics (age of the woman, duration...
Is there any relationship between the number of oocytes retrieved and cumulative live birth rates (CLBRs) in women advanced age?CLBRs increase with reproductive age up to 41 years old, added value is minimal more than futile 44 or older.CLBR actually most relevant outcome IVF from patients' perspective. There are several studies that have analysed CLBR's but some them included stimulation cycles, others not frozen embryo transfers (FETs) their analysis none has focused on age. We aimed...
To evaluate in our setting whether there is currently a level of P on the hCG day (P-hCG) predictive no pregnancy.Observational study prospectively collected data P-hCG levels stimulated IVF cycles.In vitro fertilization unit.All cycles IVF/intracytoplasmic sperm injection with fresh embryo transfer performed between January 2009 and March 2014.None.Pregnancy rate.Clinical pregnancy rate per ET was 38.7% live birth 29.1%. The concentration positively correlated to E2 day, number oocytes...
Next-generation sequencing (NGS) has the capacity of carrier screening in gamete donation (GD) programs. We have developed and validated an NGS carrier-screening test (qCarrier test) that includes 200 genes associated with 368 disorders (277 autosomal recessive 37 X-linked). Carrier is performed on oocyte candidates male partner recipient. Carriers X-linked conditions are excluded from GD program, whereas donors chosen who do not carry mutations for same gene/disease as recipients. The...
Abstract STUDY QUESTION Are progesterone (P) levels on the day before natural cycle frozen embryo transfer (NC-FET) associated with live birth rate (LBR)? SUMMARY ANSWER Regular ovulatory women undergoing NC-FET serum P <10 ng/ml blastocyst have a significantly lower LBR than those >10 ng/ml. WHAT IS KNOWN ALREADY The importance of around time in patients FET under artificial endometrial preparation has been well established. However, no study analyzed true cycle. DESIGN, SIZE,...
Early embryo freezing with saccharose and propanediol gives a survival rate of 62% the embryos if 4 cell only one intact blastomere after thawing are included. The first pregnancy achieved such an is reported as well preliminary results obtained in our IVF programme using French method.
Objective: To compare the outcomes of patients with confirmed endometriosis undergoing in vitro fertilization (IVF)-embryo transfer (ET) treated either gonadotropin-releasing hormone agonist (GnRHa) or antagonist (GnRHant) using propensity score (PS) matching.Design: Observational, retrospective analysis from January 2000 to December 2010.Setting: Private tertiary fertility clinic.Patient(s): Patients by ultrasound surgery (American Fertility Society; AFS grades I–IV) that underwent an...
BACKGROUND: Recent evidence showed that ultrasound-guided embryo transfer significantly increases successful implantation compared to the clinical touch method. It has been postulated new echodense catheters which are more readily detectable by ultrasound may refine techniques even more, thus improving IVF outcome. METHODS: A prospective, randomized, controlled trial comparing outcome for women undergoing under guidance a single healthcare provider with random assignment according...
