● `color{Brown}"Location"`: The testes are situated `color{Violet}"outside"` the `color{Violet}"abdominal cavity"` within a pouch called `color{Violet}"scrotum"`.
● `color{Brown}""`Function of scrotum: The scrotum helps in maintaining the `color{Violet}"low temperature"` of the testes (`color{Violet}"2–2.5 degree celsius"` lower than the normal internal body temperature) necessary for `color{Violet}"spermatogenesis"`.
● `color{Brown}"Dimensions of Testes"`: In adults, each testis is `color{Violet}"oval"` in shape, with a length of about `color{Violet}"4 to 5 cm"` and a width of about `color{Violet}"2 to 3 cm"`.
● The testis is covered by a `color{Violet}"dense covering"`.
● `color{Brown}"Components of Testes"`:
`star` Each testis has about `color{Violet}"250"` compartments called `color{Violet}"testicular lobules"`.
`star` Each lobule contains one to three `color{Violet}"highly coiled"` `color{Violet}"seminiferous tubules"` in which sperms are produced.
`star` Each seminiferous tubule is `color{Violet}"lined"` on its inside by two types of cells called male germ cells (`color{Violet}"spermatogonia"`) and `color{Violet}"Sertoli cells"`.
`star` The regions outside the seminiferous tubules called `color{Violet}"interstitial spaces"`, contain small blood vessels and `color{Violet}"interstitial cells"` or `color{Violet}"Leydig cells"`.
● `color{Brown}"Functions"`:
The male germ cells undergo `color{Violet}"meiotic divisions"` finally leading to `color{Violet}"sperm"` formation.
`star` The sertoli cells provide `color{Violet}"nutrition"` to the germ cells.
`star` Leydig cells synthesise and secrete `color{Violet}"esticular hormones"` called `color{Violet}"androgens"`.
`star` Other `color{Violet}"immunologically competent"` cells are also present.
