Polyorchidism is the incidence of more than two testicles. It is a very rare congenital disorder, with fewer than 200 cases reported in medical literature [1] and six cases (two horses, two dogs and two cats) in veterinary literature. [2] Polyorchidism is generally diagnosed via an ultrasound examination of the testicles. However, the diagnosis ...
The testicles of a dromedary camel are 7–10 cm (2.8–3.9 in) long, 4.5 cm (1.8 in) deep and 5 cm (2.0 in) in width. The right testicle is often smaller than the left. [49] In sharks, the testicle on the right side is usually larger. In many bird and mammal species, the left may be larger.
In most terrestrial mammals, the scrotum (pl.: scrotums or scrota; possibly from Latin scortum, meaning "hide" or "skin") [1] [2] or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin containing the external spermatic fascia, testicles, epididymides, and vasa deferentia. The ...
It holds and protects the testicles. It also contains numerous nerves and blood vessels. During times of lower temperatures, the cremaster muscle contracts and pulls the scrotum closer to the body, while the dartos fascia gives it a wrinkled appearance; when the temperature increases, the cremaster and dartos fascia relax to bring down the ...
The testicle in the male and the ovary in the female are called the primary sex organs. [1] All other sex-related organs are known as secondary sex organs . The outer parts are known as the genitals or external genitalia , visible at birth in both sexes, [ 1 ] while the inner parts are referred to as internal genitalia , which in both sexes ...
The epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
When the pituitary gland doesn’t produce LH and FSH, there’s no signaling from the brain to the testicles, and the testicles shut down. This results in male infertility and testosterone ...
The descent of the testicles consists of the opening of a connection from the testis to its final location at the anterior abdominal wall, followed by the development of the gubernaculum, which subsequently pulls and translocates the testicle down into the developing scrotum. Ultimately, the passageway closes behind the testicle.
