They have absolute control over the testes. The pituitary releases gonadotropines called follicule stimulating hormone (FSH) and luteinizing hormone (LH) which binds cell membrane receptors in the testes cells which then stimulates the production of testosterone. It also stimulates cell division (meiosis) in the testes for production of spermatozoa.

How do the pituitary hormones affect the function of the testes?
They have absolute control over the testes. The pituitary releases gonadotropines called follicule stimulating hormone (FSH) and luteinizing hormone (LH) which binds cell membrane receptors in the testes cells which then stimulates the production of testosterone. It also stimulates cell division (meiosis) in the testes for production of spermatozoa.
What are the parts of the glands?
The pituitary gland has two parts. The anterior (or front) pituitary produces hormones that affect the breasts, adrenals, thyroid, ovaries and testes, as well as several other hormones. The main glands affected by the posterior (or rear) pituitary are the kidneys.
What gland secretes hormones into the bloodstream to affect the sex organs?
The pituitary gland secretes hormones into the bloodstream to affect the sex organs. It releases the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that regulate the functioning of the testes and ovaries.
Male reproductive functions are controlled mainly by hormones from the hypothalamus and?
Male reproductive functions are controlled mainly by hormones from the hypothalamus and pituitary gland. These hormones stimulate the production of testosterone in the testes, which is responsible for sperm production, sex drive, and secondary sexual characteristics. The hypothalamus releases gonadotropin-releasing hormone (GnRH), which triggers the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH) to regulate testosterone production.
What is the Target organs of the pituitary gland?
The target organs of the pituitary gland include the thyroid gland, adrenal glands, gonads (testes or ovaries), and growth plates in bones. The pituitary gland releases hormones that stimulate these organs to produce their own hormones and perform specific functions in the body.
Which two pituitary hormones act on the ovaries and testes?
estrogen & testosterone
Which diseases or disorders affect the testes?
Cancer can affect the testes.
What are All of the endocrine glands?
Pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, testes
If the testosterone levels in a man drop the cause of the problem is probably a hormone produced in the A pituitary gland B luteinizing gland C testes D hypothalamus?
The hormone responsible for stimulating testosterone production in the testes is luteinizing hormone (LH), which is produced in the pituitary gland. Therefore, if testosterone levels drop in a man, the issue is likely related to hormone production in the pituitary gland.
What do pituitary hormones directly control?
Pituitary hormones directly control the release of hormones from other endocrine glands in the body, such as the thyroid, adrenal glands, and ovaries/testes. They also regulate growth, metabolism, stress response, and reproductive functions.
What is the function of Pituitary gland?
The pituitary gland is a gland at the base of the brain that sends signals to other glands and organs. Like the thyroid gland, adrenal glands, ovaries and testes. It directs them to produce certain hormones. A pea sized structure attached to the hypothalamus of the brain, the pituitary glands produces hormones that affect a wide range of activities, form growth to reproduction.
Name the glands of the indocrine system?
The endocrine system includes glands such as the pituitary, thyroid, adrenal, pancreas, and ovaries/testes, among others. These glands secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction.
