Luteinizing hormone

S01876886 UI317-01 Assignment #3: Reflections 1. Hormones and the brain are powerful influences on human sexual functioning. Perhaps two of the most important portions of the brain in terms of sexual functioning are the hypothalamus and the pituitary gland, which make up the HPG axis. The HPG axis consists of the hypothalamus, pituitary gland, and the gonads – gonads being the testes in males and the ovaries in females. Together, the HPG axis regulates sex hormone production in a negative feedback loop. Three important hormones that are produced from this process are follicle-stimulating (FSH) hormone; luteinizing hormone (LH); and gonadotropin-releasing hormone (GnRH.) These hormones help to regulate the pituitary gland’s production of…

Gonadotropins are hormones thattargetthestructuresinvolvedinfertilityandreproduction,inwomenitwouldbetheovaries.They are produced by the pituitary gland to trigger the production of sex hormones. Gonadotropins help create eggs and sperm.2.Some of the references talk about how “negative feedback” is involved in understanding how these drugs work.Can you explain what is meant by negative feedback?Negativefeedbackisyourbody’swayofkeepingeverythingregulatedandinharmony.3.My doctor told me that birth…

Leptin The gene LEP is found in chromosome 7 in humans. It is a protein of 167 amino acids with a four-helix bundle motif similar to that of a cytokine. It is produced mostly in the white adipose tissue. It then circulates in the bloodstream at fluctuating levels, depending on the circumstances of its production. For example, Leptin levels are normally higher at the hours between midnight and early morning; it is assumed that this is to suppress appetite during sleep. Leptin is believed to enter…

• PCOS carries with it body changes that may be more troubling for a female than the actual cause of these changes. What body changes may affect the female? How does the nurse practitioner address these with the patient? What education and counseling does the nurse practitioner offer? PCOS is the most common endocrine disease affecting women. There are multiple changes that occur within the body due to PCOS. PCOS causes an increase of LH, resulting in hyperandrogenism; in PCOS FSH is decreased.…

Their are different hormones that help in the process of pregnancy , which are called pregnancy hormones the main hormones heard about when pregnancy hormones are mentioned are HCG ( Human Chorionic gonadotropin) ,Progesterone , prolactin and estrogen . HCG is the hormone responsible for keeping the structure of where the embryo will develop at early stages (called corpus luteum) from being shed and absorbed back into the body.HCG also stimulates the secretion of progesterone and estrogen by…

ABSTRACT: Profitable animal production require high fertility animals that exhibit healthy ovarian follicles, which contributes to estradiol synthesis. Follicle maturation relies on coordination between pituitary hormones and intraovarian signaling pathways. Recently Wnt/beta-catenin signaling has been established as necessary modulators of folliculogenesis in response to FSH. In granulosa cells (GC), beta-catenin is a central key in regulation of aromatase (Cyp19a1) expression. In addition,…

Oestrogen is a female reproductive hormone that is produced inside of the ovaries. Oestrogen is also produced inside the adrenal gland located above the kidneys and in the fat cells of the body. There are three different types of oestrogen. Namely Estrone, Estradiol and Estriol. These three different types of oestrogen all have different functions and are present in different present in the body. Oestrogen is extremely important for the proper functioning of the female reproductive system. The…

production of each hormone is kept balanced by the feedback mechanism between the individual gland (the thyroid, for example), the hypothalamus, and the pituitary gland. If a gland overproduces or underproduces a hormone, the master glands register this from the amount of hormone in the bloodstream. The master glands then respond by regulating the hormonal production. The system works with great precisior; despite the fact tat the hormones are transported in the bloodstream and are disseminated…

Endocrine System The endocrine system is basically the network of glands that secrete hormones into the blood stream which regulates activities of cells or organs. The sexual development and function of the body and the metabolism are two examples of what the endocrine systems does. The major contributors to the endocrine system include the pituitary gland, thyroid, hypothalamus, parathyroid, adrenal glands, pineal body, reproductive glands, and the pancreas. The pituitary gland is…

ENDOCRINAL GLANDS Patients with anorexia nervosa have a number of abnormalities in endocrine function. Secretion rates of cortisol are generally elevated,and metabolic clearance rates are decreased, with the result that the half-life of cortisol may be prolonged in malnourished individuals. The clinical significance of this elevated cortisol level is unknown, but it may be involved with loss of bone density in anorexia nervosa(Lo Sauro et al., 2008). Alterations in growth hormone are also…
