Quality semen production remains the main focus and objective of semen processing laboratories throughout the world. Bacterial and other microbial contaminants affect the semen quality and hence the fertility, and also lead to reproductive disorders as well as lower conception rates and increased embryonic mortality, abortion and other complications in females. Microbial contamination affects the semen adversely, by exerting direct spermicidal effect, formation of reactive oxygen species, toxin production, adherence with spermatozoa, deriving nutrients and oxygen from the medium and thus competing with spermatozoa for the factors of growth and normal functioning. Despite hygienic measures, several ubiquitous and opportunistic microbes find their ways into semen during collection, processing, and storage of semen, and survive even during freezing. Stringent sanitary precautions are therefore required at every step of collecting semen and its processing. Preputial cavity is considered as main source of semen contaminating microorganisms. Flushing the preputial cavity with normal saline or any suitable liquid combination with antimicrobial activity, prior to semen collection reduces the microbial load and thereby improves the semen quality.
