Ovarian control of very low sperm/egg ratios at the commencement of mammalian fertilisation to avoid polyspermy

1 Jul 1996

Abstract excerpt

This essay considers the means whereby sperm/egg ratios close to unity are generated during the initial stages of fertilisation in placental mammals. Pre-ovulatory graafian follicles and their contents are seen to be key structures orchestrating the events of sperm progression and coordinating the subsequent meeting of male and female gametes. Three levels of control over the numbers of spermatozoa activated and...
