Luteinizing hormone

in mouse models Abstract: Estrogen is the primary female sex hormone and is responsible for the development and regulation of the female reproductive system and of secondary sex characteristics. Produced primarily by the ovaries, estrogen binds to and activates estrogen receptor beta (ER)- a nuclear receptor. Estrogen plays an important role in the hypothalamic-pituitary-gonadal (HPG) axis by acting on gonadotropin-releasing hormone (GnRH) neurons located within the hypothalamus. In females, a cyclic

Progesterone, a type of female sex hormone which belong to a steroid hormone class known as progestogen, has a major role in the development of oral contraception. Progesterone is produced in ovaries, adrenal gland and in placenta when women get pregnant. In the menstrual cycle, ovary unceasingly alternates between two phases: the follicular phase, which is characterized by the presence of maturing follicles and the luteal phase, which is governed by the presence of corpus luteum. Ovulation occurs

Gonadotropins are a group of hormones that are secreted by the pituitary gland that starts the production of the gonads. The reason gonadotropins are used in fertility is because it has FSH and LH hormone that aids in producing eggs in order for a woman to ovulate. So in other words, if a women does not have enough hormone to start ovulation she will be given a rFSH for about 12 days to help the eggs mature and then a dose of gonadotropin to start the ovulation process.

Abstract Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder diagnosed in women of reproductive age. The disease manifests itself with varying symptoms and has long term consequences of heart disease, diabetes, and infertility. PCOS has no clear etiology or pathophysiology, and as new information is being contributed, the mechanism and components of the disease is being updated. Presented here are the most understood and accepted components of PCOS, and its pathology as a reproductive

According to PubMed Health, Polycystic Ovary Syndrome (PCOS) is a condition in which women possess abnormally high level of male hormones. The high hormone levels lead to risks of irregular or absent menstrual cycles, insulin resistance, ovarian cysts, issues related to the circulatory system, obesity, heart disease, diabetes and etc. Symptoms differ between each woman therefore, despite research data collected showing that PCOS affects 5-10% of women between the age of 18-44, there are many women

Abstract Aim: We compared the quality of life related to eating and exercise (QOL ED) in women seeking fertility treatment with and without PCOS controlling for age and BMI Body Mass Index (BMI). Method: Twenty-one women with and 132 women without PCOS attending IVF clinics completed a questionnaire containing the QOL ED global score consisting of five eating disorder subscores. Results: Women with PCOS had a poorer QOL ED and were almost three times more likely to obtain a score suggestive of

well as increased androgens, cardiovascular risks and anovulation.1 Insulin aids in regulation of ovarian function and overproduction of insulin causes the ovaries to produce high amounts of androgens.9 High levels of gonadotropin releasing hormone (GnRH) stimulate the ovarian thecal cells to produce a greater amount of androgens such as 17-hydroprogesterone, testosterone and progesterone.9 Furthermore, thecal cells contain a higher level of cytochrome P450 11A, CYP17 and 3-HSD2 genes.9 Increased

(Emily and Becca) In the equine oestrous cycle, prostaglandin F2α (PGF2α) is released from the uterus following stimulation by oxytocin when there is not implantation. PGF2α has a luteolytic effect, ceasing the release of progesterone and beginning oestrus. When administered exogenously, PGF2α allows for synchronization of oestrus and shortening the interval to the 2nd postpartum oestrus and interovulatory period. To synchronize the oestrus cycle, 2 injections of PGF2α can be administered 14

Testosterone is a hormone that plays a vital role in men's health. Over time, or through various conditions, the testicular ability to produce testosterone levels declines, or fails, leaving men with lower than optimal testosterone levels. Testosterone gels for men, natural testosterone boosters, injections and patches are available to treat low levels. What Are Testosterone Gels? Testosterone gel is considered a controlled substance and is a topical treatment available by prescription used to

such as Clomiphene and Gonadotropins and lifestyle changes. Weight loss is the number one lifestyle change a woman can take. Due to the body’s ability to create excess insulin, increasing the androgen production. Androgen being the result of the hormone imbalance is what contributes most to the male –pattern symptoms. Complications that come with PCOS are infertility, type 2 diabetes, depression, eating disorders
