Breast size and insecurities
Sex selection As early as BC, Aristotle prescribed the ligation tying off of the left testicle in men wishing to have boys. This was because people believed that the right testicle made "boy" sperm and the left made "girl" sperm. The original Latin word testis, "witness", was used in the firmly established legal principle "Testis unus, testis nullus" one witness [equals] no witness , meaning that testimony by any one person in court was to be disregarded unless corroborated by the testimony of at least another. This led to the common practice of producing two witnesses, bribed to testify the same way in cases of lawsuits with ulterior motives. Since such "witnesses" always came in pairs, the meaning was accordingly extended, often in the diminutive testiculus, testiculi. The primitive jawless fish have only a single testis, located in the midline of the body, although even this forms from the fusion of paired structures in the embryo. The right testicle is often smaller than the left. Their testes are located outside of the body, suspended by the spermatic cord within the scrotum. There are several hypotheses why most boreotherian mammals have external testes which operate best at a temperature that is slightly less than the core body temperature, e. The classic hypothesis is that cooler temperature of the testes allows for more efficient fertile spermatogenesis. In other words, there are no possible enzymes operating at normal core body temperature that are as efficient as the ones evolved, at least none appearing in our evolution so far. The early mammals had lower body temperatures and thus their testes worked efficiently within their body. However it is argued that boreotherian mammals have higher body temperatures than the other mammals and had to develop external testes to keep them cool. It is argued that those mammals with internal testes, such as the monotremes, armadillos, sloths, elephants, and rhinoceroses, have a lower core body temperatures than those mammals with external testes. It has been suggested that the ancestor of the boreoeutherian mammals was a small mammal that required very large testes perhaps rather like those of a hamster for sperm competition and thus had to place its testes outside the body. This position is made less parsimonious by the fact that the kangaroo , a non-boreoeutherian mammal, has external testicles. The ancestors of kangaroos might, separately from boreotherian mammals, have also been subject to heavy sperm competition and thus developed external testes, however, kangaroo external testes are suggestive of a possible adaptive function for external testes in large animals. One argument for the evolution of external testes is that it protects the testes from abdominal cavity pressure changes caused by jumping and galloping. Mild, transient scrotal heat stress causes DNA damage, reduced fertility and abnormal embryonic development in mice. The relative size of testes is often influenced by mating systems. In the mammalian kingdom, there is a tendency for testicular size to correspond with multiple mates e. Production of testicular output sperm and spermatic fluid is also larger in polygamous animals, possibly a spermatogenic competition for survival. Chimpanzees have high promiscuity and large testes compared to body weight 0. Human testicular size falls between these extremes 0. Amphibians and most fish do not possess seminiferous tubules. Instead, the sperm are produced in spherical structures called sperm ampullae. These are seasonal structures, releasing their contents during the breeding season, and then being reabsorbed by the body. Before the next breeding season, new sperm ampullae begin to form and ripen. The ampullae are otherwise essentially identical to the seminiferous tubules in higher vertebrates , including the same range of cell types. These are two healthy testicles. Heat causes them to descend, allowing cooling. A healthy scrotum containing normal size testes. The scrotum is in tight condition. The image also shows the texture.
