== Puberty ==

* Puberty in the male is generally defined as the time when he is capable of successfully mating a female and getting her pregnant.

** Can vary with breed, genetics, nutrition and climatic changes.

== Seasonality ==

=== Seasonality ===

* Changes in sexual behaviour, morphology and function of the genital organs, as well as changes in endocrinological profiles.

* Changes in sexual behaviour, morphology and function of the genital organs, as well as changes in endocrinological profiles.

* Very variable but generally coincides with the period of low humidity, low temperature, and increased rainfall.

=== Anatomical Evidence for Seasonality ===

==== Anatomical Evidence for Seasonality ====

* Increase in size and activity of the testis and accessory glands during the coolest months of the year.

* Increased secretory activity of the poll glands giving the characteristic smell of the rutting male.

* Increased secretion of androgen, especially testosterone.  

* Increased secretion of androgen, especially testosterone.  

* Serum prolactin levels are high during the non-breeding season and decrease significantly in the rutting season.

* The overlapping nature of follicular waves and the fact that the female is receptive even if the [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|follicle]] is not mature enough to [[The_Ovary_-_Ovulation_-_Anatomy_%26_Physiology|ovulate]] makes it difficult to determine from behaviour when the optimum time for mating is.
