Introduction
Generally, puberty can be defined in both sexes as the ability to accomplish reproduction. The fundamental requirement for the onset of puberty is the secretion of GnRH at the appropriate frequency and quantity to stimulate gonatotrophin release by the anterior pituitary gland. Gonadotrophins promote:
- Gametogenesis
- Steroidogenesis
- Development of reproductive organs
The degree of function of neurons in the hypothalamus that secrete GnRH increases as puberty begins. The function of these neurons may be influenced by:
- Plane of nutrition
- Exposure to certain environmental or social cues
- Genetics
Male
Age when Behavioural Traits are Expressed
- Generally acquire reproductive behavioural traits such as mounting and erection a long time before they acquire the ability to ejaculate and produce spermatozoa.
- Behavioural traits are easy to determine, as mouting behaviour and erection can be easily observed.
