Filter by:Gonadotropin-releasing hormone (GnRH) is a hormone that regulates the ability of the pituitary to secrete two hormones, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH control the production of female hormones (such as estrogen and progesterone) and the development of eggs by the ovary. Progesterone and estrogen then decrease the number of GnRH pulses produced by the brain (and therefore the number of LH pulses from the pituitary). The ability to decrease GnRH pulses seems to be very important for normal menstrual function in adult women. The purpose of this study is to learn more about how GnRH and LH pulses are controlled during puberty. The information gathered in this study will hopefully allow us to learn more about how menstrual cycles are normally established in girls during puberty.
Girls with high levels of the male hormone testosterone often develop polycystic ovary syndrome (PCOS) as adults. Women with PCOS often have irregular menstrual periods, excess facial and body hair, and weight gain. Women with PCOS also have difficulty becoming pregnant. Some, girls with high levels of male hormone will develop normal hormone levels as they grow up. Most girls continue to have high levels of male hormone as adults. In addition, girls with elevated levels of male hormones often have lower fertility rates in adulthood. In this study the investigators will aim to discover the effect of 7 days of estrogen and progesterone on GnRH pulses in girls and women with the goal of understanding how and why some girls and women have higher levels of male hormone and the causes of PCOS. If investigators understand the causes of these disorders, they may be able to better treat them and perhaps even learn how to prevent the development of PCOS.
Whether 12 weeks of spironolactone can reduce androgen production from ovaries and adrenal glands of girls with obesity and androgen excess
This study will test whether metformin administration can ameliorate androgen (male hormone) overproduction in overweight pubertal girls with androgen excess. The investigators hypothesize that improvement in insulin sensitivity by 12 weeks of metformin administration will improve androgen levels after adrenal stimulation testing with adrenocorticotropic hormone (ACTH) or ovarian stimulation testing with recombinant human chorionic gonadotropin (rhCG).
This study will test whether longer-term suppression of adrenal function can ameliorate androgen (male hormone) overproduction in overweight early pubertal girls with androgen excess. The investigators hypothesize that suppression of nighttime adrenocorticotropin hormone (ACTH) production by 12 weeks of evening oral hydrocortisone administration will improve androgen levels in girls with adrenal androgen overproduction. Specifically, this intervention will improve androgen levels after adrenal stimulation testing with ACTH or ovarian stimulation testing with recombinant human chorionic gonadotropin (rhCG).
Short term hydrocortisone to test whether improves excess androgen production from adrenal gland and ovaries
This study will test whether short-term suppression of ovarian function can ameliorate androgen (male hormone) overproduction in overweight girls with androgen excess. The investigators hypothesize that one dose of depot leuprolide agonist administration will improve androgen levels in girls with ovarian androgen overproduction. Specifically, this intervention will improve androgen levels after ovarian stimulation testing with recombinant human chorionic gonadotropin (rhCG).
Women with polycystic ovary syndrome (PCOS) often have irregular menstrual periods, too much facial and body hair, and weight gain. Women with PCOS also have a hard time becoming pregnant. Girls with high levels of the male hormone testosterone often develop PCOS as adults. Some girls with high levels of male hormone will develop normal hormone levels as they grow up, but most girls continue to have high levels of male hormone as adults. The purpose of this study is to understand where the male and female hormones come from in girls as they get older. The investigators think the adrenal gland, makes most of the hormones in young girls and that the ovary and the adrenal gland make these hormones in older girls. The investigators would like to find out whether an overactive adrenal gland makes these hormones higher in girls who are overweight, compared to those who are not overweight.
The purpose of this study is to learn if obese pre- and early pubertal girls with hyperandrogenemia (HA) are more insulin resistant (i.e., have lower insulin-stimulated glucose disposal) compared to obese peripubertal girls without HA; and that overnight mean luteinizing hormone (LH) concentration is also an independent predictor of free testosterone concentrations, especially in mid- to late pubertal girls.
