Superfetation is the simultaneous occurrence of more than one stage of developing offspring in the same animal.
A freemartin or free-martin is an infertile cow with masculinized behavior and non-functioning ovaries. Phenotypically, the animal appears female, but various aspects of female reproductive development are altered due to acquisition of anti-Müllerian hormone from the male twin. Genetically, the animal is chimeric: karyotypy of a sample of cells shows XX/XY chromosomes. The animal originates as a female (XX), but acquires the male (XY) component in utero by exchange of some cellular material from a male twin, via vascular connections between placentas: an example of microchimerism. The chimerism is mainly present in the hematopoietic stem cells.

Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study. Semen can be collected via masturbation, prostate massage, artificial vagina, penile vibratory stimulation (vibroejaculation) and electroejaculation. Semen can be collected from endangered species for cryopreservation of genetic resources.
The estrous cycle is a set of recurring physiological changes induced by reproductive hormones in females of mammalian subclass Theria. Estrous cycles start after sexual maturity in females and are interrupted by anestrous phases, otherwise known as "rest" phases, or by pregnancies. Typically, estrous cycles repeat until death. These cycles are widely variable in duration and frequency depending on the species. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Many mammals used in commercial agriculture, such as cattle and sheep, may have their estrous cycles artificially controlled with hormonal medications for optimum productivity. The male equivalent, seen primarily in ruminants, is called rut.

Reproductive endocrinology and infertility (REI) is a surgical subspecialty of obstetrics and gynecology that trains physicians in reproductive medicine addressing hormonal functioning as it pertains to reproduction as well as the issue of infertility. While most REI specialists primarily focus on the treatment of infertility, reproductive endocrinologists are trained to also test and treat hormonal dysfunctions in females and males outside infertility. Reproductive endocrinologists have specialty training (residency) in obstetrics and gynecology (ob-gyn) before they undergo sub-specialty training (fellowship) in REI.
Veterinary obstetrics are the obstetrical methods used in veterinary medicine, which are quite different from those of human medicine. Veterinary obstetrics is a branch of veterinary medicine that deals with medical and surgical care together with manipulations of the female animals in breeding, gestation, labor, puerperium, and care of the newborn.

A prosection is the dissection of a cadaver or part of a cadaver by an experienced anatomist in order to demonstrate for students anatomic structure. In a dissection, students learn by doing; in a prosection, students learn by either observing a dissection being performed by an experienced anatomist or examining a specimen that has already been dissected by an experienced anatomist.
Aglepristone is a synthetic, steroidal antiprogestogen related to mifepristone which is marketed by Virbac in several European countries for use in veterinary medicine. It is specifically used as an abortifacient in pregnant animals. Aglepristone, similarly to mifepristone, also possesses some antiglucocorticoid activity.
