A gonad, sex gland, or reproductive gland [1] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [2] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells
Streak gonads are a form of aplasia, resulting in hormonal failure that manifests as sexual infantism and infertility, with no initiation of puberty and secondary sex characteristics. [ 4 ] Gonadal development is a process, which is primarily controlled genetically by the chromosomal sex ( XX or XY ), which directs the formation of the gonad ...
Male gonad (testes, left) and female gonad (ovaries, right) Males have two testicles of similar size contained within the scrotum, which is an extension of the abdominal wall. [1] Scrotal asymmetry, in which one testicle extends farther down into the scrotum than the other, is common. This is because of the differences in the vasculature's ...
The first appearance of the gonad is essentially the same in the two sexes, and consists in a thickening of the mesothelial layer of the peritoneum. The thick plate of epithelium extends deeply, pushing before it the mesoderm and forming a distinct projection. This is termed the gonadal ridge. The gonadal ridge, in turn, develops into a gonad.
As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr-+ -o-+ -logy = arthrology), but generally, the -o-is dropped when connecting to a vowel-stem (e.g. arthr-+ -itis = arthritis, instead of arthr-o-itis). Second, medical roots generally go together according to language, i.e., Greek ...
This is also known as a prepucectomy, as the medical term for the foreskin is the prepuce. Proctocolectomy is the removal of the colon or the large intestine and the rectum. Prostatectomy is the removal of the prostate gland.
The primary sex organs are the gonads, a pair of internal sex organs, which diverge into testicles following male development or into ovaries following female development. [8] As primary sex organs, gonads generate reproductive gametes containing inheritable DNA. They also produce most of the primary hormones that affect sexual development, and ...
