Male (♂) refers to organisms with the physiological sex which 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.
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.
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.
