spermatozoa in the female reproductive tract - Coggle Diagram
spermatozoa in the female reproductive tract
transport into female tract
#
retrograde loss (moved into vagina from cervix)
phagocytosis by neutrophil
cervix
removal of non-motile sperm
removal of some abnormal sperm
"privileged pathways" (low viscosity areas)
uterus
capacitation initiated: sperm exposed to the female tract will shed plasma coatings, exposing molecules that can bind to zona pellucida of oocyte
phagocytosis
oviduct
docking to oviductal cells
capacitation completed
hyperactive motility
binding of zona pellucida
#
fertilization
acrosome reaction: fusion of spermatozoal plasma membrane & outer acrosomal membrane
spermatozoon penetrates zona pellucida of oocyte
sperm-oocyte membrane fusion: cortical membrane formed, prevents further sperm from penetrating oocyte
sperm engulfed

major barrier to spermatozoal transport & can also serve as reservoir for spermatozoa
insemination directly into uterine body/horns decreases sperm loss
