Comparison between two cryopreservation techniques of human ovarian cortex: morphological aspects and the heat shock response (HSR)
Cell stress & chaperones ·doi:10.1007/s12192-022-01252-6

This study was tailored to compare the cryopreservation of the human ovarian cortex using closed metal container vitrification or the slow-freezing technique. Superficial ovarian cortical tissue biopsies were collected from 12 participants …

Morphology-based selection from available euploid blastocysts induces male-skewed sex proportion in the offspring
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-021-02235-9

PURPOSE: To determine whether blastocyst morphology has an impact on sex proportion at pre-implantation and birth in PGT-A and non-PGT-A cycles. METHODS: A total of 1254 biopsied blastocysts from 466 PGT-A cycles were analyzed for sex prop…

Preimplantation genetic testing for aneuploidies does not increase success rates in fresh oocyte donation cycles: a paired cohort study
Journal of assisted reproduction and genetics ·doi:10.1007/s10815-021-02339-2

PURPOSE: To determine whether in vitro fertilization cycles using fresh oocyte donations benefit from preimplantation genetic testing for aneuploidies. METHODS: A paired cohort study compared 44 fresh oocyte donation cycles with or without…

Electrophysiological Responses to Different Follicle-Stimulating Hormone Isoforms on Human Cumulus Oophorus Cells: Preliminary Results
Revista brasileira de ginecologia e obstetricia : revista da Federacao Brasileira das Sociedades de Ginecologia e Obstetricia ·doi:10.1055/s-0038-1676037

OBJECTIVE: The aim of the present study was to provide a better understanding of the specific action of two follicle-stimulating hormone (FSH) isoforms (β-follitropin and sheep FSH) on the membrane potential of human cumulus cells. METHODS…
