Nature's motility blockers: controlling human sperm motility machinery from the outside. Chemical characterization of a peritoneal fluid lipid that induces sperm immobilization.

abstract：:To mimic post-ovulatory ageing, we have extended the in vitro maturation (IVM) phase to 48 h and examined effects on (i) developmental potential, (ii) expression of a panel of developmentally important genes and (iii) gene-specific epigenetic marks. Results were compared with the 24 h IVM protocol (control) usually em...
