What is seminiferous tubules and its function?
Functions of Seminiferous Tubules The seminiferous tubules function to produce sperm, maintain sperm, and store the sperm. During the process of meiosis the sertoli cells that line the seminiferous tubules undergo the process of differentiation to be converted into sperm.
Where are the seminiferous tubules?
the testes
Seminiferous tubules are coiled (for the most part) tubules found within the testes. They are the site where spermatozoa (male gametes) are produced.
Do females have seminiferous tubules?
They secrete androgen-binding protein, a binding protein which increases the concentration of testosterone inside the seminiferous tubules. Embryologically, they also secrete the anti-Müllerian hormone (AMH) necessary for the female Müllerian ducts to regress….

What are seminiferous tubules Class 12?
Answer. The production of sperms in the testes takes place in a highly coiled structure called the seminiferous tubules. These tubules are located in the testicular lobules. Each seminiferous tubule is lined by germinal epithelium.
What do the seminiferous tubules produce?
Testes Produce Spermatozoa. Spermatozoa are produced within structures called the seminiferous tubules. These tubules contain stem cells called spermatogonia (singular is spermatogonium) that derive from primordial germ cells that enter the testis during embryogenesis.
What is produced in seminiferous tubules?
The testes have two functions – to produce sperm and to produce hormones, particularly testosterone. Sperm are produced in the seminiferous tubules of the testes.
Do seminiferous tubules produce testosterone?
The main hormone secreted by the testes is testosterone, an androgenic hormone. Testosterone is secreted by cells that lie between the seminiferous tubules, known as the Leydig cells. Testosterone is important in maintaining these secondary male characteristics throughout a man’s life.
What is the function of the seminiferous tubules?
The seminiferous tubules are the site of the germination, maturation, and transportation of the sperm cells within the male testes. Seminiferous tubules are made up of columnar Sertoli cells surrounded by spermatogenic cells on the epithelial interior and stem cells exteriorly.
Where are the seminiferous cells located in the testes?
Seminiferous tubules are located within the testes, and are the specific location of meiosis, and the subsequent creation of male gametes, namely spermatozoa . The epithelium of the tubule consists of a type of sustentacular cells known as Sertoli cells, which are tall, columnar type cells that line the tubule.
Are there Leydig cells in seminiferous tubules?
The nodules are demarcated from the surrounding testicular tissue. The nodules do not show Leydig cell hyperplasia but may contain Leydig cells ( Fig. 9-57 ). Nodules have been designated Sertoli cell adenomas based on the predominant Sertoli cell composition and their often substantial size ( Fig. 9-58 ).
