Anatomy and Physiology of Animals/Reproductive System - Wikibooks, open books for an open world

Breeding horses is a precarious business at best. Despite great strides in research, conception rates overall are not high. In many cases, blame is placed on the mare. She is too old, she has uterine cysts, scar tissue, abnormal perineal conformation, a malfunctioning endocrine system—and the list goes on. However, it takes two to reproduce, and there are times when the problem can lie with the stallion. Before we can discuss what those problems might be, or what is involved in getting maximum reproductive efficiency from a stallion, we must understand the unique anatomy and physiology of the unaltered equine male.

Odyssey of the spermatozoon

Spermatogenesis is the process of the gradual transformation of germ cells into spermatozoa. It occurs mainly within the seminiferous tubules of the testes and can be divided into three phases, each of which is associated with different germ cell types:. Unlike the female production of gametes which occurs entirely before birth, with gamete maturation occurring in a pulsatile fashion after puberty, males produce gametes continuously from puberty onwards for the rest of their reproductive lives and the release of the gametes is constant. The seminiferous tubules are the site of spermatogenesis. The two main cell types within the tubules involved in spermatogenesis are the germ cells, which will develop into sperm, and somatic cells known as Sertoli cells , which nuture the germ cells throughout the development process.
