Sexual maturity

Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood,[1] but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions.[1][2]
Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.)
Role of reproductive organs
Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied by a growth spurt or other physical changes which distinguish the immature organism from its adult form. In animals these are termed secondary sex characteristics, and often represent an increase in sexual dimorphism.[clarification needed]
After sexual maturity is achieved,[clarification needed] some organisms become infertile, or even change their sex. Some organisms are hermaphrodites and may or may not be able to "completely" mature and/or to produce viable offspring. Also, while in many organisms sexual maturity is strongly linked to age, many other factors are involved, and it is possible for some to display most or all of the characteristics of the adult form without being sexually mature. Conversely it is also possible for the "immature" form of an organism to reproduce. This is called progenesis, in which sexual development occurs faster than other physiological development (in contrast, the term neoteny refers to when non-sexual development is slowed – but the result is the same - the retention of juvenile characteristics into adulthood).[citation needed]
Puberty vs. sexual maturity
In bulls, there is a fundamental difference between puberty and sexual maturity.[3]

The definition of puberty alone can encompass the process of sexual maturation, but a more expansive approach is to think of puberty in combination with the term adolescence. This differentiation prompts the practitioner to consider the psychological, behavioral, and social changes of the adolescent who is experiencing pubertal development.
