Male mammals ejaculate semen through the penis into the female reproductive tract during copulation. [28] [29] Ejaculation usually occurs after only one intromission in humans, canids, and ungulates, but occurs after multiple intromissions in most mammal species. [30] [31] Copulation can induce ovulation in mammal species that do not ovulate ...
In mammals, the major organs of the reproductive system include the external genitalia (penis and vulva) as well as a number of internal organs, including the gamete-producing gonads (testicles and ovaries). Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted infections. [3]
A sex organ, also known as a reproductive organ, is a part of an organism that is involved in sexual reproduction. Sex organs constitute the primary sex characteristics of an organism. Sex organs are responsible for producing and transporting gametes , as well as facilitating fertilization and supporting the development and birth of offspring.
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
In placental mammals, offspring are born as juveniles: complete animals with the sex organs present although not reproductively functional. After several months or years, depending on the species, the sex organs develop further to maturity and the animal becomes sexually mature.
The different uterine morphologies among the mammals are due to varying degrees of fusion of the Müllerian ducts. Various congenital conditions of the uterus can develop in utero. Though uncommon, some of these are didelphic uterus, bicornate uterus and others. [21] See also List of related male and female reproductive organs.
The clitoris (/ ˈ k l ɪ t ər ɪ s / ⓘ or / k l ɪ ˈ t ɔːr ɪ s / ⓘ; pl.: clitorises or clitorides) is a female sex organ present in mammals, ostriches and other amniotes.. Although the clitoris exists in all mammal species, [1] [2] [3] most studies deal with the human clitoris - few detailed studies of the anatomy of the clitoris in non-humans exist. [4]
