How does sperm response to follicle fluid? <\/p>\n\n\n\n
“Mate choice can continue after mating via chemical communication between the female reproductive system and sperm. While there is a growing appreciation that females can bias sperm use and paternity by exerting cryptic female choice for preferred males, we know surprisingly little about the mechanisms underlying these post-mating choices. In particular, whether chemical signals released from eggs (chemoattractants) allow females to exert cryptic femqale choice to favour sperm from specific males remains an open question<\/strong>, particularly in species (including humans) where adults exercise pre-mating mate choice. Here, we adapt a classic dichotomous mate choice assay to the microscopic scale to assess gamete-mediated mate choice in humans. <\/p>\n\n\n\n We examined how sperm respond to follicular fluid, a source of human sperm chemoattractants, from either their partner or a non-partner female when experiencing\u00a0\u2026”<\/p>\n\n\n\n Source: <\/p>\n\n\n\n
