Key diagnostic feature of Freemartinism
Presence of vestigial seminal vesicles
Paraovarian cysts are remnants of
persistent Wolffian/Mesonephric ducts
Functional anovulatory follicular cysts produce
Estrogen

a. Horse
b. Pig
c. Cow
d. Dog
Horse
Cow

a. Horse
b. Cow
c. Pig
d. Bitch
Cow
Uterine rupture due to torsion causes
If the cervix is open the fetus _ _
Mummification
Putrefies
Uterine hemorrhage in the dog & cat
Normal hemorrhage at periphery of placentation
blood breakdown give green coloration at parturition
Uterine involution progression
Mare
Cow
Mare - 9 days
Bovine - caruncles desquamate in 10 days; endometrial epithelial repair complete by 50 days
Metritis
Inflammation of entire uterine wall
Hormonal influences of pyometra in the
Cow
Dog
Horse
Cow - PGF2alpha
Dog - Progesterone
Horse - not important

b. Uterine infection
c. Viral infection
d. Unknown
d. Unknown
T/F Bacterial infection is present in fetal mummification
T/F Bacterial infection is present in fetal maceration
False
True (low virulence bacteria)
Hydramnios or Hydrallantois?
Fetal malformation causes
Adventitial placentation causes
Hydramnios
Hydrallantois
Most common genital tumor of the Bitch
Most common tumor of the Bovine vulva
Bitch - Genital Fibroleiomyoma
(estrogen related in the bitch but not other species)
Bovine - Fibropapilloma of vulva
Tumor of dogs that can be transferred by intact cells….not a virus.
