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.
