The primary source of estrogen (or oestrogen in UK spelling) is the woman's ovaries; secondary sources include the placenta, the liver, the breasts, the adrenal glands, and fat cells in general. Men also produce it too, in much smaller amounts.
Once produced, the hormones spread throughout the body. Besides helping to regulate the menstrual cycle, they play an important role in various systems throughout the body: affecting muscles, bones, and the reproductive and circulatory systems.

This is released after 6 days in the ovaries
A hormone called auxin, which is produced in the apical meristem or shoot tip of a plant, can affect the growth and development of other parts of the plant. It can regulate processes such as cell elongation, root development, and leaf growth. Auxin moves through the plant's vascular system and can affect different tissues and organs.
Anterior pituitary gland. It secretes Growth hormone,Thyroid stimulating hormone,Adrenocorticotrophic hormone, Follicle stimulating hormone,Leutenizing hormone,Prolactin hormone.
This accounts for Growth Hormone Regulatory Hormone, also called Growth Hormone Releasing Hormone, and also GRHF (for Growth Hormone Regulatory Factor). This is one of the two hypothalamic hormones (or previously named 'factors') that, respectively, stimulate or inhibit the release of growth hormone from the pituitary gland. The other hormone that inhibits the release of growth factor is called Growth Hormone Releasing-Inhibiting Hormone (or factor).
Growth hormone (GH) is a protein-based peptide hormone. It stimulates growth, cell reproduction and regeneration in humans and other animals
Receptors for that hormone
Estrogen's are produced primarily by developing follicles in the ovaries, the corpus luteum, and the placenta. Luteinizing hormone (LH) stimulates the production of estrogen in the ovaries. Some estrogen's are also produced in smaller amounts by other tissues such as the liver, adrenal glands, and the breasts. These secondary sources of estrogens are especially important in postmenopausal women. Fat cells also produce estrogen,[6] potentially being the reason why underweight or overweight are risk factors for infertility.

In the female gonads - ovaries. Other hormone they produce is progesterone. These are sex hormones which regulate menstrual cycle, activate mammary glands and regulate the feminine characteristics of body shape.
It is a substance that is produced by a endocrine gland in one part of the body, passes into the bloodstream and is carried to other organs or tissues, where it acts to modify their structures or function. Example of hormones are cortico steroids, adrenaline, growth hormone, androgens, oestrogen,thyroid hormone and insulin. Hormones have a dramatic and broad range of effects on metabolism, growth and maturation, sexuality and reproduction, and other important bodily functions.
It is the hormone estrogen. It is secreted by ovaries.
The Pituitary gland releases hormones that trigger the testes (testicles) in males to produce testosterone, and the ovaries to produce oestrogen in females.
To a much lesser defgree, in the ovaries and in the adrenal glands.
Ovaries secrete two kind of hormones: estrogens and progestrogens. The principal estrogen secreted by the ovary is estradiol (regulates the devolpment of external sexual characteristics of females and menstrual cycle). The main progestrogen is progesterone which acts during menstrual cycle and prepares the inner revetment of uterus for pregnancy.
The hypothalamus in the brain releases Gonadotropin-Releasing Hormone to the pituitary gland, located in your brain behind the eyes. The pituitary gland releases Follicle-Stimulating Hormone (FSH) and Luteinizing Hormone (LH), which go to the ovaries. FSH stimulates the selection of an egg from the ovary, and a surge of LH release stimulates the release of the egg for fertilzation. In the ovary, Theca cells release Testosterone which travels to nearby Granulosa cells which convert the testosterone to estrogen. Theca cells also make progesterone, which is necessary for growing the endometrium, which is what bleeds during the menstrual cycle.
a girl is a girl because she has a vagina, and the hormone estrogen inside her. she also has other female organs such as the ovaries, the clit, boobs, and alot more.
The anterior lobe. Other hormones produced by the anterior lobe include thyroid stimulating hormone, follicle stimulating hormone, and adrenocorticotropic hormone.
Hormones that target other endocrine glands. Produced by anterior pituitary. Include: FSH, TSH, LH, ACTH.
The main hormones that are involved in puberty are testosterone for males and oestrogen (can also be spelt 'estrogen') and progesterone for females. These are released from a gland in the brain called the pituitary gland. Other hormones include follicle-stimulating hormone (FSH) and luteinising hormone (LH).
