Sex

Sex is a coffee table book written by Madonna, with photographs taken by Steven Meisel Studio and film frames shot by Fabien Baron. The book was edited by Glenn O'Brien and was released on October 21, 1992, by Warner Books, Maverick and Callaway Books. Approached with an idea for a book on erotic photographs, Madonna expanded on the idea and conceived the book and its content. Shot in early 1992 in New York City and Miami, the locations ranged from hotels and burlesque theaters, to the streets of Miami. The photographs were even stolen before publishing, but were quickly recovered. The book had a range of influences – from punk rock to earlier fashion iconoclasts like Guy Bourdin and his surrealism, and Helmut Newton, in its stylized, sado-masochistic look. Sex has photographs that feature adult content and softcore pornographic as well as simulations of sexual acts, including sadomasochism and analingus. Madonna wrote the book as a character named "Mistress Dita", inspired by 1930s film actress Dita Parlo. It also includes cameos by actress Isabella Rossellini, rappers Big Daddy Kane and Vanilla Ice, model Naomi Campbell, gay porn star Joey Stefano, actor Udo Kier, socialite Tatiana von Fürstenberg, and nightclub owner Ingrid Casares.

Sex

Sex is a trait that determines an individual's reproductive function, male or female, in animals and plants that propagate their species through sexual reproduction. The type of gametes produced by an organism define its sex. Commonly in plants and animals, male organisms produce smaller gametes (spermatozoa, sperm) while female organisms produce larger gametes (ova, often called egg cells). Organisms that produce both types of gametes are called hermaphrodites. During sexual reproduction, male and female gametes fuse to form zygotes that develop into offspring that inherit a selection of the traits of each parent. Males and females of a species may be similar (sexual monomorphism), or have physical differences (sexual dimorphism). The differences reflect the different reproductive pressures the sexes experience. For instance, mate choice and sexual selection can accelerate the evolution of physical differences between the sexes. The terms male and female typically do not apply in sexually undifferentiated species in which the individuals are isomorphic (look the same) and the gametes are isogamous (indistinguishable in size and shape), such as the green alga Ulva lactuca. If there are instead functional differences between gametes, such as in fungi, they may be referred to as mating types.Sex is genetically determined in most mammals by the XY sex-determination system, where male mammals carry an X and a Y chromosome (XY), whereas female mammals carry two X chromosomes (XX). Other chromosomal sex-determination systems in animals include the ZW system in birds, and the X0 system in insects. Various environmental systems include temperature-dependent sex determination in reptiles and crustaceans.
