These organs are located on the outside of the body, and within the pelvis. The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant.
Harvestmen are the only male arachnids that have a penis. In male insects, the structure analogous to a penis is known as an aedeagus. The male copulatory organ of various lower invertebrate animals is often called the cirrus. [32] In 2010, entomologist Charles Linehard described a new genus of barkflies called Neotrogla.
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 human anatomy, the penis (/ ˈ p iː n ɪ s /; pl.: penises or penes; from the Latin pēnis, initially "tail" [1]) is an external sex organ (intromittent organ) through which males urinate and ejaculate. Together with the testes and surrounding structures, the penis functions as part of the male reproductive system.
The sex organs of the green algae Chara are the male antheridia (red) and female archegonia (brown) 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.
“The intensity of a male orgasm can be amplified by many factors,” says Dr. James Elist, M.D., ... “The brain is the body's most important sexual organ, so one of the best
The male reproductive system contains two main divisions: the testicles where sperm are produced, and the penis where semen is ejaculated through the urethra. 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 ...
Aedeagus of Pentodon idiota Photomicrograph of the aedeagus of water scavenger beetle Tormissus linsi (from above). An aedeagus (/ i ˈ d i. ə. ɡ ə s / or / i. d i ˈ eɪ. ɡ ə s / [1] [2] pl. aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.
