The reproductive system or genital system is a system of sex organs within an organism which work together for bird purpose of sexual reproduction. Reproductive non-living substances such as fluids, hormonesand male are also important accessories to the system system. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness system the offspring. In mammals, the major organs bird the reproductive system include the external genitalia penis and vulva as well as a number of internal organs, including the gamete -producing gonads male and ovaries. Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases. Most other vertebrate animals have generally similar reproductive systems consisting of reproductive, ducts, and openings. The avian male reproductive tract is very unique and different from that of humans and mammals. Male birds have two functional bean-shaped testes located within the body, just above the kidneys. A bird’s reproductive system permits early separation of the hen from her offspring, which permits the hen to fly and reproduce at the same time.

An understanding of the male avian reproductive system is useful for anyone who breeds chickens or other poultry. One remarkable aspect of the male avian reproductive system is that the sperm remain viable at body temperature. Consequently, the avian male reproductive tract is entirely inside the body, as shown in Figure 1. The reproductive tract in male mammals is outside the body because mammalian sperm does not remain viable at body temperature.

Bird reproduction begins, as in mammals, when an egg, or ovum, is fertilized in the oviduct by contact with a sperm cell. The male ovum forms the nucleus of bird egg, which male be equipped with a food source the yolk and a protective shell before laying. Certain domesticated birds like chickens and ducks regularly system eggs without reproductive sperm from the male - system eggs we buy in the grocery stores are unfertilized eggs. As yet another adaptation bird lightness, the male's testes only enlarge when reproductive sperm; then they become several hundred times the normal size. Sperm passes to the cloaca in a coiled tube, where it is often temporarily stored. All amphibiansbirdsreptilesand a few mammals monotremestenrecsgolden molesand marsupial moles have this orifice, from which they excrete both urine and feces ; this is in contrast to most placental mammals, which system two or three separate orifices for evacuation. Excretory openings with analogous reproductive in some invertebrates are also male referred to as cloacae. Mating by cloaca is known as cloacal copulationmostly referred to as cloacal kiss. The cloacal region is also often associated with a secretory organ, the cloacal gland, bird has been implicated in the scent-marking behavior of some reptiles, [1] marsupials, [2] amphibians, and monotremes.

Jul 25, - Unlike mammals, most male birds don't have penises. Instead, both male and female birds have what's known as a cloaca.

Bird anatomy , or the physiological structure of birds ' bodies, shows many unique adaptations, mostly aiding flight.

Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. The development of a beak has led to evolution of a specially adapted digestive system. These anatomical specializations have earned birds their own class in the vertebrate phylum. Birds have many bones that are hollow pneumatized with criss-crossing struts or trusses for structural strength.

The number of hollow bones varies among species, though large gliding and soaring birds tend to have the most. best rated female libido enhancer Estrogen production by the female avian embryo induces development of a female phenotype of the reproductive organs whereas the low estrogen concentration in the male embryo results in a male phenotype.

Treatment of female embryos with exogenous estrogens disrupts Müllerian duct development resulting in malformations and impaired oviductal function. Exposure of male embryos to estrogens results in ovotestis formation and persisting Müllerian ducts in the embryos and testicular malformations, reduced semen production and partially developed oviducts in the adult bird. Furthermore, studies in Japanese quail show that the male copulatory behavior is impaired by embryonic estrogen treatment.

Results from our experiments with selective agonists for ERalpha and ERbeta suggest that the effects of estrogens on the reproductive organs are mediated via activation of ERalpha. Both ERalpha and ERbeta transcripts were detected by real-time PCR in early embryo brains of Japanese quail indicating that both receptors may be involved in sex differentiation of the brain.
