The Sertoli cells usually form the blood-testis barrier.

Sertoli cells are also known as "sustentacular cells."

Sertoli cells, which are found in the testes, are stimulated primarily by follicle-stimulating hormone (FSH), which is produced by the pituitary gland. FSH acts on the Sertoli cells to promote sperm production and development, as well as to maintain the microenvironment necessary for sperm maturation.

Sertoli-Leydig cell tumor is a rare cancer of the ovaries. The cancer cells produce and release a male sex hormone.
Alternative NamesArrhenoblastoma; Androblastoma
SymptomsThe Sertoli cells are normally located in the male reproductive glands (the testes). They feed sperm cells. The Leydig cells, also located in the testes, release a male sex hormone called testosterone.
In men, some cancers of the testes can start in the Sertoli and Leydig cells. These are considered types of testicular cancer.
Sertoli-Leydig cell tumor is a cancer that starts in the female ovaries. The cancer cells produce and release a male sex hormone. This hormone may cause the woman to develop male physical characteristics (virilization), including facial hair and a deep voice.

No, Sertoli cells do not produce sperm. They provide support and nourishment for developing sperm cells in the seminiferous tubules of the testes. Sperm cells are produced by germ cells through the process of spermatogenesis.

Inhibin is produced in the Sertoli cells in the testis and in the granulosa cells in the ovary.
1 answer
Spermiogenesis occurs within the Sertoli cells found in the seminiferous tubules of the testes.

No, sustentacular cells are found in the olfactory epithelium of the nasal cavity and support the olfactory receptor neurons, while Sertoli cells are found in the testes and provide support and nourishment to developing sperm cells. They have different functions and locations in the body.

inhibin & ABP ( androgen -binding pro.)
1 answer
Testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
LH stimulates the testicular Leydig cells to produce testosterone.
FSH stimulates the testicular Sertoli cells that nurture the developing sperm cells. Sertoli cells are also dependent testosterone.
1 answer
Sertoli cells within the seminiferous tubules of the testes provide physical and nutritional support to the developing germ cells of the spermatogenic lineage. They regulate the microenvironment within the tubules, provide structural support, and also secrete various factors necessary for sperm production.
2 answers
The sertoli cell is the one that secretes nutrients for the growing sperm.
6 answers
LH, or luteinizing hormone, stimulates the Leydig cells in the testes to produce testosterone. Testosterone plays a critical role in maintaining male reproductive function, including sperm production and development of secondary sexual characteristics.

Sertoli cells are the testicular cells that construct the blood-testis barrier. They form tight junctions between neighboring cells to create a barrier that prevents harmful substances from entering the semen. The blood-testis barrier helps maintain the unique microenvironment required for sperm production within the testes.
2 answers
Follicle stimulating hormone (FSH) causes the Sertoli cells of the testes (which help nurse developing sperm cells). This begins the process of spermatogenesis in the testes.
3 answers
Sertoli cells extend inward from the periphery of the seminiferous tubule and provide nourishment to the spermatids as they undergo spermiogenesis. They create a protected microenvironment for the development of sperm, secrete necessary nutrients and hormones, and play a crucial role in maintaining the blood-testis barrier.

produce FAS ligand which will initiate apoptosis in T cells and have tight junctions which normally prevents exposure of germ cells to cells of the immune system

Parts of Frog testis are
Tunica albuginea - thick white fibrous layer that covers your testis.
Intersitial cells - specialized cell for the production of testosterone.
Basement Membrane- thin fibrous layer encapsulating the semineferous tubule.
Seminiferous tubule- contained developing sperm.
spermatogonia - small cells arranged in a single layer at the periphery of the seminiferous tubules
Sertoli cells - columnar cells which are elongated and tall. Support production of your spermatogonia
Primary and Secondary Spermatocyte - will become sperm cell in the process of spermatogenesis and spermiogenesis.
Spermatids - product of Secondary spermatocyte that already pass in the proces of meiosis 2.
Sperm cell - for reproduction purposes.

Sperm cells have an immature stage in the testes and maturation occurs as the sperm move through the testicular system. There can be multiple reasons for ejaculate to contain immature sperm cells. The mechanical reason is high frequency of intercourse. Another reason for failure would occur in the epididymis where the
Sertoli cells facilitate maturation.
Causes can be adult mumps, hormonal issues, drugs/medication, radiation, genetic anomalies and excess heat.

Most cases (95 percent) of testicular cancer originate in undeveloped cells (germ cells) that produce sperm.
These tumors, called germ cell tumors (GCTs), are most common in men between the ages of 20 and 40 and are curable more than 95 percent of the time. There are two main types of GCTs: seminomas and nonseminomas. A third type, called stromal tumors, develops in the supporting tissues of the testicle.
Testicular cancer may also develop in the supportive, hormone-producing tissue of the testicles (stroma). This type accounts for 4 percent of testicular cancer in men and 20 percent of cases in boys.
Types of stromal tumors include Leydig cell tumors and Sertoli cell tumors.

the interstitial cells.they can be called that too,but they were named first by the professor leydig who discovered them and who was born in the 1850 s,and they are derived from the undifferentiated mesenchymal cells of testes after puberty

Lumens form in the testicular gonadal cords during differentiation of Sertoli cells, which help to create the seminiferous tubules where sperm production takes place. This process typically occurs around mid-gestation in male development.
