Membrane transfer from oocyte to sperm occurs in two CD9-independent ways that do not supply the fertilising ability of <i>Cd9</i> -deleted oocytes

Abstract excerpt

Spermatozoa undergo regulation of their functions along their lifespan through exchanges via vesicles or interactions with epithelial cells, in the epididymis, in the seminal fluid and in the female genital tract. Two different ways of oocyte membrane transfer to spermatozoa have been described: trogocytosis and exosomes. We here report an analysis of in vitro exchanges between the membranes of unfertilised...
