anestrus time when a female is not actively in the heat cycle
artifical insemination (AI) the practice of breeding female animals through the use of veterinary equipment rather than the traditional mating methods
artifical vagina (AV) sterile sleeve or tube used to collect the semen of an animal during the ejaculation process
bilateral cryptorchid both testicles are retained and do not descend into the scrotum
castration surgical removal of the testicles in male animals
cervix end of the vagina that opens to the urethra
cloaca external reproductive area where egg laying animals pass urine, feces, and eggs, also called the vent
conception process of creating a new life that forms an embryo
contraction first stage of labor when the fetus begins to move into the uterus to prepare for birth by moving into the birth canal
cooled semen process of transporting and storing sperm for use within 24 hours-48 hours due to cool temperature
corpus luteum (CL) knowns as the yellow body of the ovary, forms to allow an ovary to increase in size as an egg develops
diestrus stage of the heat cycle when pregnancy occurs and is characterized by a functional CL that releases progesteron to maintain pregnancy
dystocia difficult labor
embryo cell that developes into a newborn life
epididymus tube that transports sperm from the seminiferous vesicles to the vas deferens
estrogen main female reproductive hormone that causes behavior changes in females during the estrus cycle and also allows follicle production and development to occur
estrus the time when the female animal is receptive to breeding or mating with a male
estrus cycle heat cycle in female animals when the female is receptive to mating with a male
fertilization uniting of egg and sperm to allow an embryo to form
flagella tail of sperm that allows movement
follicl tiny structures within the ovary that enlarge with egg development and allow ovulation to occur
follicle stimulating hormone (FSH) hormone released to allow a follicle to grow and allow ovulation to occur
frozen semen method of shipping and storing sperm in liquid nitrogen, may be frozen and stored for up to 40 years
genitalia reproductive organs
genitals reproductive organs
gestation length of pregnancy
HORMONE chemicals that are produced by the body that allow for sexual reproduction to occur in both males and females
incubation the process of increased temperature to allow an embryo to grow
induced ovulation occurence of the release of the egg at a time sperm is introduced when fertilization occurs at mating
infundibulum funnel within the uterus where an egg developes in an egg laying animal
involution the process of the uterus shrinking after labor
isthmus shell membran of an animal that lays eggs
lordosis exhibiting a prayer position where the front end of the body is lowered to the ground with the back end held high in the air
lutenizing hormone (LH) allows an egg to develop and be released in the ovary during metestrus
masectomy surgical removal of the mammary glands
metestrus stage of the heat cycle following estrus when ovulation occurs
mouth brooder fish that carry their eggs in their mouth for incubation to protect and allow hatching
ovarian cyst small masses that develop on the ovary of an intact female animal, causing eggs not to develop and sterility
ovariohysterectomy (OHE) term for a spay, surgical removal of the ovaries and uterus
ovary the part of the uterine horn that allows egg development and is the primary female reproductive organ in egg growth
oviduct smal tube on the end of the uterine horn that is tapered and holds the ovary
ovulation the release of the egg from the ovary
ovum egg yolk in an animal that lays eggs
parturition the labor process
penis the male external reproductive organ used in breeding and mating
placenta tissue and membrane collection that connect from the fetus to the mother to allow nutrients to be absorbed during gestation
polyestrus many heat cycles occur at regular intervals throughout the breeding season
prepuce the skin that covers and protects the penis in male animals
proestrus stage of the heat cycle before estrus that releases the progesterone hormone prior to mating
progesterone hormone produced to maintain pregnancy
prolapse uterus condition where the uterus and vaginal tissue separate from the body and allow the uterus body to be passed outside the body
pyometra severe infection of the uterus in female intact animals that causes the uterus to fill w pus
reproductuve system the organs in the body responsible for both male and female breeding and reproduction
scrotum skin over the two testicles that protects and controls temperature for sperm production
semen fluid that transports sperm during reproduction
semen collection procedure using specialized veterinary equipment to collect sperm from male animals to be used in breeding practices
semen morphology process of determining if sperm is adequate for transport and breeding by analyzing the quality and quantity
seminiferous vesicles tubes located within the testicle that transports sperm to the testicles
septic buildup of bacteria in the system causing a toxic effect when it gets into the bloodstream
sperm male reproductive cell developed in the testicles
standing heat the female animal will stand for breeding when a male is present
sterile not able to reproduce
tail flagging holding the tail high in the air during the estrus cycle
testicle the primary reproductive organ in the male that holds sperm
testosterone main male reproductive hormone that produces male characteristics and is essential for sperm production
unilateral cryptorchid one retained testicle that has not descended into the scrotum
urethra narrow tube that connects the male and female reproductice organs to the urinary system
uterine horn two parts of the uterus that holds single or multiple embryos that expand as the embryos grow
utuers large hollow reproductive organ that holds an embryo during the gestation period and is y shaped
vagina internal female reproductive organ tht allows mating and labor to occur
vas deferens small tube that transports sperm from the testicles to the outside of the body
vent external area where eggs are laid in egg bearing animals, also called the cloaca
vulva external beginning of the reproductive system in the female where urine is excreted
winking movement of the vulva with frequent vagina ldischarge and urination
