ovari-o-hyster-ectomy excision of the ovaries and the uterus
py-o-metra pus in the uterus
mast-itis inflammation of the breast/mammary tissue
gesta-tion the state of bearing; refers to the state of the reproductive cycle in which the female is carrying young in the uterus
parturi-tion the state of birthing
lacta-tion the state of milking
post-parturi-ent pertaining to after birth; postpartum
Dys-toc-ia the process of difficult birth
Neo-nat-al pertaining to newly born
muta-gen-ic pertaining to change producing; clinically refers to anything that alters the DNA to create genetic abnormalities
teratoj-gen-ic pertaining to monster producing; clinically refers to anything that causes physical defects in the developing embro/fetus.
pro-estrus before estrus; clinically refers to the period of the reproduction cycle before sexual receptivity
estrus a recurring period of sexual receptivity and fertility in many female mammals; heat.
an-estrus absence of estrus; clinically refers to the period in the reproductive cycle in which the female animal is in sexual quiescence (diestrus-the period between metestrus and the next proestrus)
met-estrus beyond/after; clinically refers to the period of the reproductive cycle after sexual receptivity
The Estrous Cycle (British spelling, oestrous) is the main reproductive cycle of other species females of non-primate vertebrates, for example rats, mice, horses, pig have this form of reproductive cycle. Also do not confuse with "estrus", which is a phase of the cycle.

Paraparesis he partial paralysis of both legs. It is characterized by progressive weakness and spasms in the legs.
