Retractor Penis Muscle
retracts penis after erection subsides (bulls, bucks and rams)
Penis
male copulatory organ
Sertoli cells
provide
nutrients for

site of oogenesis
Oviduct/Fallopian tube
site of fertilization
Uterine horns/Uterus
site of pregnancy
Cervix
thick walled organ that produces
mucus for lubrication during estrus (cow and

sometimes called “yellow
body”, formed from remaining cells in follicle
that has ovulated
What is unique about equine ovary?
Inside out
