A male (♂) organism is the physiological sex that produces sperm. Each spermatozoon can fuse with a larger female gamete, or ovum, in the process of fertilization. A male cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs.
Not all species share a common sex-determination system. In most animals, including humans, sex is determined genetically, but in some species it can be determined due to social, environmental or other factors. For example, Cymothoa exigua changes sex depending on the number of females present in the vicinity.
The existence of two sexes seems to have been selected independently across different evolutionary lineages (see convergent evolution). The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gametes of male and female types to oogamous species in which the female gamete is very much larger than the male and has no ability to move. There is a good argument that this pattern was driven by the physical constraints on the mechanisms by which two gametes get together as required for sexual reproduction.

Plot: Belgrade in 1963. In a yard surrounded by buildings, a group of young people of different backgrounds and social status, but of similar views about love and self-affirmation, spend their time together. Their friendship is dyed with various events typical for socialism, such as working actions or Youth Day's parade. All what happens within this yard may become an allegory of one generation's destiny.

The struggle between males and females leads to a host of weird adaptations, from chastity belts to anti-aphrodisiacs.

Você não pensou, você abusou
Da mulher que muitos querem e não têm
E extrapolou, causando ardor
Mas há males na vida que vêm para o bem
Você não pensou, você abusou
Da mulher que muitos querem e não têm
E extrapolou, causando ardor
Mas há males na vida que vêm...
Se você pedisse e soubesse agradecer
Iria fazer alguém feliz
Mas teu egoísmo não deixou acontecer
O destino é quem não quis
Ontem mesmo eu vi a tua "ex" passar por mim
Com um sorriso bem maior
O oposto do dia que encontrei você
Chorando aos prantos e só
Realmente agora sei o que é ter alguém
Não me sinto mais tão nu
Estou valorizando cada qual que me convém
Colorindo mais azul
Hoje, ao lado dela
Pois você não soube amar
Certo é dar pra receber
Não estou feliz
Com teu jeito de sofrer
Mas fizestes por merecer
