Reproductive system of the dog and cat Part 2 – the male system

ABSTRACT: The male reproductive system has evolved to produce spermatozoa by a process of spermatogenesis, to secrete fluids which both aid the survival of the sperm and transports them into the female tract, and also to secrete the hormone testosterone which is essential in the development of male characteristics and patterns of behaviour. The parts of the reproductive tract all play a part in these functions and in delivery of the sperm into the female tract, where they are able to fertilise the female ova. The anatomy of the reproductive systems in the dog and the tomcat are similar and any significant differences are highlighted.
