An Introduction to Animal Sexuality

Animals are multicellular, unicellular organisms in the organism Kingdom Animalia. Although they are protozoans, true animals are classified as suborders such as Prototheria, Eutheria, Chordata, Rodentia, Order Rodentia, and Suborder Characinha. With few exceptions, all animals eat organic matter, breathe oxygen, can move, reproduce sexually, and have feelings. They also have complex emotions such as joy, fear, pain, anger, love, hate, and sorrow. All animals share these traits.


Because of the similarities between all animal species, many of them are used for research and studies in the animal sciences. An animal such as a mouse or a fish contains innumerable numbers of nerve cells, muscles, organs, glands, bones, and other tissues. In fact, an animal’s anatomy is so extensive that if one knew how to collect it all, it would be the largest single storage area on earth. Animals are used for scientific and medical research in the form of animal physiology, medical research, pharmacology, histology, veterinary medicine, zoology, ecology, physiology, population control, wildlife management, animal behavior, physiology, population planning, disease ecology, nutrition, pathophysiology, immunology, and physiology. Some animal professionals conduct independent research or work in support of human scientists in the same fields.

Because of advances in modern medicine, more people are able to participate in animal sciences research and study. More people are able to participate in animal breeding and raising. More people are able to practice animal care and animal husbandry. All of this raises the bar for those who want to advance in their careers.

Animal husbandry involves a wide variety of activities ranging from breeding and raising healthy and disease-free livestock to collecting and studying wild animals. There are also animal experiments that focus on studying specific diseases, traits, behavior, environment, and intelligence. For example, some researchers may focus on studying how various diseases affect wild primates. Others will be conducting experiments with lab mice to determine the effects of various pesticides.

The majority of animal experiments are usually carried out in zoos or research facilities. However, there are many private owners who own exotic animals, such as lions, elephants, hippos, monkeys and snakes. These animals are usually bred in captivity and then are offered for adoption, sale or display. Many organizations offer asexual reproduction services, such as inbreeding, gene mapping and selective breeding. When animals have desirable characteristics, they can be offered for adoption or sale to experienced and knowledgeable breeders and private owners.

Asexual reproduction occurs when the same sperms (male and female) are allowed to mate and produce children. This happens in all mammals including humans. A sexual reproduction process occurs when one sex cells implant in a female’s reproductive organ and this creates eggs which are transferred to the male sperm through the vagina. Therefore, whether the animals were created specifically as sexual is not really relevant because they will still mate and produce offspring whether they were created as a result of sexual reproduction.
