stages of male gamete
spermatogonia - primary spermatocytes- secondary spermatocyte - spermatid- spermatozoa - sperms
spermatogenesis
formation of sperms
spermiation
withdrawal of the sperms from the Sertoli cells
LH acts on which cells and controls
Leydig cells and spermatogenesis
FSH acts on whcih cell and controls
Sertoli cells and spermiation
cap like structure of sperms
acrosomes
the middle piece of sperm contains
mitochondria
human male ejaculates how many sperms at once
200 million
criteria for sperm activity
60% normal shape and 40% motility
once the oogaonia enters the 1st meiotic division it gets arrested at
prophase 1 and is called the primary oocyte
receptors present on the sperms
fertilizin
cells surrounding the oocytes
granulosa cells
secondary follicles charaters
new theca and more granulosa cells
fluid filled sac of teritary follicle
antrum
