What is required for The secretion of each of the hormones from the anterior pituitary?
The anterior pituitary produces luteinizing hormone and follicle stimulating hormone. Both are gonadotropins.
What are characteristic of hormones?
Hormones are the chemicals which are produced by glands. By definition they pour there secretion/secretions in blood. Blood carry the secretion through circulation to target organ/ organs for desired effect. Usually target organ sends back the message to reduce the secretion of the hormone producing gland. This is called as negative feed back effect. (Like thyroid stimulating orAdrenocorticotrophic hormone by anterior pituitary gland.) Sometimes hormone like Follicle stimulating hormone stimulates ovarian follicle. Which in turn produces hormone estrogen. Main female hormone. Thyroid hormones increase the 'basal metabolic rate' of body.
How do cells in the ovary detect a hormone from the brain?
Hormones are produced and then circulate through the body systemically. The target organ (in this case the Ovary) has receptors that react to the influence of the hormone through direct interaction of the hormone and the receptor. FSH (follicle stimulating hormone) CG (chorionic gonadotrophin) and LH (Leutinizing Hormone) along with progesterone, prostiglandin and estrogen are hormones that create feedback between the pituitary gland (brain) and the ovaries creating the reproductive cycle.
How does GnRH get from the hypothalamus to the anterior pituitary and what effects does it have on the pituitary?
The hypophysial portal system carries gonadotropin-releasing hormone (GnRH) from the hypothalamus to the anterior pituitary. It stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary.

What hormone in the male body causes a man to be drawn toward females through puberty?
None, because not all males are drawn to females through puberty or at any other time.
How does estrogen prevent ovulation?
Estrogen prevents ovulation primarily through its regulatory effects on the hypothalamus and pituitary gland. It inhibits the release of gonadotropin-releasing hormone (GnRH), which decreases the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This suppression of LH and FSH prevents the ovarian follicles from maturing and ovulating. Additionally, high levels of estrogen can create a negative feedback loop, further reducing the likelihood of ovulation.
Which hormone spikes midway through the menstrual cycle and triggers ovulation?
Luteinizing hormone (LH) Luteinizing hormone (LH) secreted by the pituitary gland causes the mature ovarian follicle to rupture, a process called ovulation. -masteringbiology.com
How create sperms in human body?
Sperms are produced in the testes through a process called spermatogenesis, which involves the division and differentiation of germ cells into mature sperm cells. This process is regulated by hormones such as testosterone and follicle-stimulating hormone (FSH). Sperms are stored in the epididymis and are released during ejaculation.
What are the effects of the pituitary hormones?
Pituitary hormones play a crucial role in regulating various physiological processes in the body. They influence growth, metabolism, and reproduction through hormones such as growth hormone (GH), which stimulates growth and cell reproduction, and luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are key in regulating the menstrual cycle and sperm production. Additionally, adrenocorticotropic hormone (ACTH) stimulates cortisol production in the adrenal glands, affecting stress response and metabolism. Overall, pituitary hormones coordinate the activity of other endocrine glands, maintaining homeostasis.
When will a boy go through puberty if he is almost 17 and still has not reached puberty?
Some boys can start very late, into their late teens. However, if you are concerned, speak to your doctor about possible hormone issues.
