do theca cells have fsh receptors?

Main findings (Results) Follicle‐stimulating hormone receptor expression in the granulosa cells was induced by androgens that were derived from growth differentiation factor‐9‐stimulated theca cells. In the theca cells, luteinizing hormone receptor (LHR) expression was noted from their appearance.

GnRH is a hormone produced in the hypothalamus region of the brain. GnRH moves through the bloodstream to the pituitary gland. There, it binds to certain receptors. Those receptors signal the pituitary gland to create two more hormones: LH and follicle-stimulating hormone (FSH).

Gonads. The gonads, the primary reproductive organs, are the testes in the male and the ovaries in the female. These organs are responsible for producing the sperm and ova, but they also secrete hormones and are considered to be endocrine glands.

When the primordial follicle is stimulated, it becomes a primary follicle. The oocyte enlarges, and the follicular cells divide. A follicle that has two layers of follicular cells is called a primary follicle. These cells continue to hypertrophy and proliferate to form many layers surrounding the oocyte.

This simply means they are the primary reproductive organs. In addition to their role in producing ova, the ovaries also have the distinction of being an endocrine gland because they secrete hormones—primarily estrogen and progesterone—that are vital to normal reproductive development and fertility.

Luteinizing hormone and follicle-stimulating hormone, which are produced by the pituitary gland, promote ovulation and stimulate the ovaries to produce estrogen and progesterone. Estrogen and progesterone stimulate the uterus and breasts to prepare for possible fertilization.

At the start of the cycle, a brain region called the hypothalamus signals the pituitary gland to release follicle stimulating hormone (FSH). FSH stimulates the ovaries to create several small sacs called follicles.

Estrogen receptors (ER) and progesterone receptors (PR; also called PgR) may be found in breast cancer cells. Cancer cells with these receptors depend on estrogen and related hormones, such as progesterone, to grow.

Hormone receptors are proteins — found in and on breast cells — that pick up hormone signals telling the cells to grow. A cancer is called estrogen-receptor-positive (or ER+) if it has receptors for estrogen.

hMG acts directly on the ovaries to stimulate the development of eggs. It is an injected medicine. Follicle-stimulating hormone or FSH (Gonal-F®, Follistim®): FSH works much like hMG. It causes the ovaries to begin the process of developing eggs.

The Leydig cells make and secrete testosterone, in response to lutenising hormone from the pituitary. ... FSH stimulates the Sertoli cells to secrete androgen-binding protein into the lumen of the seminiferous tubules.

The pituitary gland produces FSH which causes the development of a follicle in the ovary. As the egg develops inside the follicle, the follicle produces the hormone oestrogen. The oestrogen causes growth and repair of the lining of the uterus wall. Oestrogen inhibits FSH.

The majority of mature B cells outside of the GALT reside within lymphoid follicles of the spleen and lymph nodes, where they encounter and respond to T cell–dependent foreign antigens bound to follicular dendritic cells (DCs), proliferate, and either differentiate into plasma cells or enter GC reactions.

The gonadotropins (LH, FSH and hCG) bind to cells in the ovaries and testes, stimulating the production of the steroid sex hormones estrogen, testosterone (T), and dihydrotestosterone (DHT).

FSH stimulates an immature follicle to grow. Once it is grown, it releases estradiol, which signals the release of GnRH and LH, prompting ovulation. Prior to ovulation, FSH levels will peak, signaling the ovary to release an egg.

Tropic Hormones: FSH & LH The four tropic hormones of the anterior pituitary gland are: follicle-stimulating hormone (FSH), luteinizing hormone (LH), adrenocorticotropic hormone (ACTH), and thyroid-stimulating hormone (TSH). ... Follicle-stimulating hormone stimulates the production of egg and sperm.

Theca cells from sheep, humans, and primates principally produce androstenedione, whereas rodents produce testosterone as precursors for estradiol production in the neighboring granulosa cells.
