Correlations between clinical parameters, blastocyst morphological classification and embryo euploidy.

Objective: The aim of the present study was to evaluate clinical and embryo parameters to predict embryo ploidy.

Methods: In this retrospective analysis, we studied 838 biopsied day-5 blastocysts from 219 patients in the period from May 2021 to July 2022. All embryos were morphologically classified before biopsy and were divided into two groups according to genetic test results.

Serum progesterone level in luteal phase improves pregnancy rate in fresh cycles with blastocyst embryo transfer.

Objective: To assess the association between serum level of progesterone during stimulation and in the luteal phase with pregnancy rate in a cohort of patients undergoing in vitro fertilization and embryo transfer (IVF-ET) on day 5.

Methods: Retrospective Cohort Study. Patients: 62 infertile women, aged 24-42 years, undergoing ART at our center from May 2019 to May 2021.

A comparison of the effects of three different estrogen used for endometrium preparation on the outcome of day 5 frozen embryo transfer cycle.

Objective: To evaluate the effects of three different estrogen used for endometrium preparation on pregnancy rate, as well as hormone profile on day 5 frozen embryo transfer (FET) cycles.

Methods: Retrospective, observational study. Setting: A tertiary teaching and research private reproductive medicine center.

Which ovarian reserve marker relates to embryo quality on day 3 and blastocyst; age, AFC, AMH?

Objective: The aim of the present prospective study was to evaluate which ovarian reserve marker would be more reliable as the quality of the A + B embryos (day 3 and blastocyst).

Methods: We ran a prospective study with 124 infertile women, aged 24-48 years, from 2017 to 2018. The patients were divided into 3 groups according to age and the subgroups were compared for AMH, AFC, number of A+B embryos.

The impact of dehydroepiandrosterone in poor ovarian responders on assisted reproduction technology treatment.

One in six couples worldwide will experience at least one infertility problem during their reproductive years. Between 5.6% and 35.

A comparison of the effects of three luteal phase support protocols with estrogen on in vitro fertilization-embryo transfer outcomes in patients on a GnRH antagonist protocol.

Objective: This study aimed to evaluate the effects of three different luteal phase support protocols with estrogen on the pregnancy rates and luteal phase hormone profiles of patients undergoing in vitro fertilization-embryo transfer (IVF-ET) cycles. A secondary objective was to evaluate which ovarian reserve markers correlated with pregnancy rates.

Methods: This retrospective observational study was carried out at a private tertiary reproductive medicine teaching and research center.

Age as A Predictor of Embryo Quality Regardless of The Quantitative Ovarian Response.

Background: One determining factor of a successful fertilization (IVF) cycle is embryo quality. The aim of the present study was to evaluate associations of embryo quality and reserve markers like age, FSH and AMH.

Materials And Methods: In this prospective study, 120 infertile women, aged 21-44 years, undergoing routine exploration during an unstimulated cycle preceding assisted reproductive technology (ART) at our center were studied prospectively, from February 2011 to December 2014.

[Evidence of follicle responsiveness to FSH by antimüllerian hormone in ovulating women].

Purpose: to test the hypothesis that the anti-müllerian hormone (AMH) serum level reflects the antral follicles' response to the administration of FSH.

Methods: prospective study, including 116 normo-ovulatory infertile patients submitted to controlled ovarian hyperstimulation with GnRH and FSH agonists. The AMH serum level was measured after reaching the pituitary suppression and before the FSH administration (basal day).

Mock embryo transfer does not affect uterine contractility.

Objective: To assess the degree of utero-stimulation induced by transcervical introduction of a catheter as in mock ET.

Design: Prospective study.

Setting: Reproductive medicine unit.

Early follicle development alters the relationship between antral follicle counts and inhibin B and follicle-stimulating hormone levels on cycle day 3.

Objective: To verify whether, during the luteal-follicular transition, increased inhibin B production by abnormally large follicles modifies the expected relationship between the number of follicles and peripheral inhibin B and FSH levels.

Design: Prospective study.

Setting: Teaching hospital, France.

Optimal reproductive competence of oocytes retrieved through follicular flushing in minimal stimulation IVF.

The objective of this study was to assess the reproductive competence of oocytes obtained by follicular flushing in poor responder patients. This prospective comparative study, at the University of Paris XI, Assistance Publique des Hopitaux de Paris, INSERM Unit 782, was performed on 165 infertile IVF embryo transfer candidates. A total of 271 consecutive minimal stimulation IVF cycles were studied.
