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

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

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 El…
