Affective encounters in the lab - bænkpres of Work with sperm Aktivitet: Sebastian Mohr - Foredragsholder Afdeling for Sundhedstjenesteforskning In order to ship sperm samples around the globe sperm donors need to ejaculate into specimen cups. These ejaculates are then processed by bio-technicians at the laboratory of each sperm bank before private clients or fertility clinics can use portions of these samples for either home inseminations or possible assisted treatments at clinics. Yet, as rich ethnographic research on reproductive technologies has shown, standards and official guidelines are only one part of what work at a laboratory looks like. Based on ethnographic fieldwork at Danish and American sperm banks I want to look at the affective encounters in migration bank laboratories and the role these encounters play when handling and processing sperm. The technicians in the labs face the challenge of having to work with a substance deemed taboo. But contrary to the notion that sperm is a fluid not supposed to be touched outside of intimate encounters with one self or sperm sexual partners I want to argue that the routinized working procedures at sperm bank laboratories actually build on the affective encounters with sperm, and are not simply a way of dealing with them. Mammalian spermatozoon structure, function, and size Humans. The human sperm cell is the reproductive cell in males and will only survive in warm environments; once it leaves the male body the sperm's survival likelihood is reduced and it may die, thereby decreasing the total sperm kidle.pakken.se cells come in two types, "female" and "male". The sperm whale is the largest toothed whale, with adult males measuring up to metres (67 ft) long and weighing up to 57, kilograms (56 long tons; 63 short tons).
