Semen can be harvested through electroejaculation, digital manipulation, and artificial vaginas. Electroejaculation is used on large, dangerous animals and paralyzed humans, while digital manipulation is used on domestic animals. Artificial vaginas are used to collect semen from horses and sheep. The best method depends on the animal or person’s health.
A few different methods of harvesting semen are electroejaculation, digital manipulation, and artificial vaginas (AVs). Electroejaculation is the anal insertion of a probe that encourages a male to ejaculate and is commonly used on endangered animals and paralyzed humans. Finger manipulation refers to applying pressure and massage to an animal’s genitals, although this is only done safely on pets. AVs are lubricated rubber tubes used to collect semen from sheep, horses and rabbits. The best method for collecting semen depends on the animal or person and their health.
Electroejaculation is a method of collecting semen by stimulating the nerves near the prostate using electrical currents. The muscles contract and the mammal eventually ejaculates into a container, usually while sedated. This method is used on large, dangerous animals such as bulls, animals that need to be farmed but cannot be farmed due to disease or injury, and humans. When used on animals, it is usually because the animal is too dangerous to approach when attempting to breed, the animal cannot reproduce due to disease or injury, or the animal is in danger without a compatible mate nearby. Electroejaculation is used on male men who have suffered a spinal injury or cannot ejaculate without assistance for other reasons.
Digital manipulation involves massaging an animal’s genitals until it ejaculates into a vial. This semen collection method is most commonly used on domestic animals, such as stallions and cats. It is usually helpful to have a female dog or cat nearby to encourage the male animal. Digital manipulation is essentially a form of masturbation, which is also a way to harvest sperm in humans. In this case, the male usually masturbates to ejaculation in a vial in private.
AVs are rubber tubes, which are lubricated before use, with a collection vial attached to the end. They are a way to collect sperm from animals such as horses and sheep, but they can be dangerous if the animal has the slightest chance of attacking humans. Sometimes a teaser female is used, but this can end up accidentally in the female being bred or in the spread of disease. The animal is often trained to mount a dummy instead of a real animal by associating pleasure with the sight of the dummy. However, dummy mounts have their problems; for example, the animal may not stay mounted long enough to ejaculate, which is not usually the case with a teaser female.
