Definitions:

Males

Referring to the male sex or gender, biologically characterized by XY chromosomes, producing sperm for reproduction.

Primary Sex Characteristics

The physical features directly involved in the reproductive process, such as the ovaries in females and testes in males.

Secondary Sex Characteristics

Physical features that emerge during puberty which are not directly involved in reproduction but distinguish the two sexes, such as breast development and facial hair.

Females

Females refer to the sex of a species that is typically associated with the production of ova (eggs) and, in many species, with certain primary and secondary sex characteristics.
