The tetraamine spermine is biosynthesized from the triamine spermidine, which is produced from the diamine putrescine. Anton van Leeuwenhoek, the microscopy pioneer, described spermine crystals in human semen in 1678, and spermidine was also first detected in sperm. Despite their names, both polyamines are ubiquitous in organisms and have several biological functions.
