What do the male sex organs do? - - NCBI Bookshelf

All living things reproduce. Reproduction — the process by which organisms make more organisms like themselves — is one of the things that sets living things apart from nonliving things. In the human reproductive process, two kinds of sex cells, or gametes, are involved. Both the male and female reproductive systems are essential for reproduction. Humans pass certain characteristics of themselves to the next generation through their genes, the special carriers of human traits.

Male reproductive system

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 ; however, species such as Cymothoa exigua change 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. 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.
