The male external genitalia include the penis and the scrotum. The female external genitalia include the clitoris, the labia, and the vestibule, which are collectively called the vulva. External genitalia vary widely in external appearance among different people. One difference between the glans penis and the glans clitoridis is that the glans ...
External genitalia of an adult female (left) and male (right). The human reproductive system includes the male reproductive system, which functions to produce and deposit sperm, and the female reproductive system, which functions to produce egg cells and to protect and nourish the fetus until birth. Humans have a high level of sexual ...
The human reproductive system usually involves internal fertilization by sexual intercourse. During this process, the male inserts their erect penis into the female 's vagina and ejaculates semen, which contains sperm. The sperm then travels through the vagina and cervix into the uterus or fallopian tubes for fertilization of the ovum.
The female reproductive tract is made of several connected internal sex organs—the vagina, uterus, and fallopian tubes —and is prone to infections. [1] The vagina allows for sexual intercourse, and is connected to the uterus at the cervix. The uterus (or womb) accommodates the embryo by developing the uterine lining.
The male reproductive system contains two main divisions: the testicles where sperm are produced, and the penis which discharges the sperm in semen during ejaculation. In humans, both of these organs are outside the abdominal cavity. Having the testicles outside the abdomen facilitates temperature regulation of the sperm, which require specific ...
Hermaphrodite. A hermaphrodite (/ hərˈmæfrəˌdaɪt /) is a sexually reproducing organism that produces both male and female gametes. [1] Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic. [2] The individuals of many taxonomic groups of animals, primarily invertebrates, are ...
The development of the reproductive system is the part of embryonic growth that results in the sex organs and contributes to sexual differentiation. Due to its large overlap with development of the urinary system, the two systems are typically described together as the genitourinary system. The reproductive organs develop from the intermediate ...
Uterus. The uterus (from Latin uterus, pl.: uteri) or womb (/ wuːm /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more embryos until birth. [1] The uterus is a hormone -responsive sex organ that contains glands in its lining that secrete ...
