Pulmonate land gastropods are simultaneous hermaphrodites and their reproductive system is complex. It is all completely internal, except for genital protrusion (eversion) during mating. The outer opening of the reproductive system is called the "genital pore"; it is positioned on the right-hand side, very close to the head of the animal.
They are the only accessory reproductive glands in male monotremes. Placental mammals usually have one pair of bulbourethral glands, [ 3 ] while male marsupials have 1–3 pairs. [ 3 ] [ 4 ] [ 5 ] Of all domesticated animals, they are absent only in dogs.
The mammalian male reproductive system contains two main divisions, the penis and the testicles, the latter of which are where sperm are produced and usually held in a scrotum. [5] In humans, both of these organs are outside the abdominal cavity , but they can be primarily housed within the abdomen in other animals.

The vas deferens (pl.: vasa deferentia), ductus deferens (pl.: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens.

The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones , and pheromones are also important accessories to the reproductive system. [ 1 ]
The uterine horns are far more prominent in other animals (such as cows [1] and cats [2]) than they are in humans. In the cat, implantation of the embryo occurs in one of the two uterine horns, not the body of the uterus itself.
