Background: Functional hypothalamic amenorrhea (functional HA) is a condition where a woman s period stops for a temporary time. This is due to improper function of the hypothalamus. This is the part of the brain that directs the whole reproductive system. Researchers want to learn more about functional HA. They also want to learn how diet, exercise, and other factors may change women s menstrual cycles. Objective: To better understand functional HA. Eligibility: Healthy women ages 18-28 years old who: * Have regular periods * Exercise no more than 4 hours a week * Had their first period at age 11-14 Design: Participants will be prescreened over the phone. Participants will be screened with: * Blood and urine tests * Medical history * Physical exam. Participants will have 9 or 10 visits over about 3 menstrual cycles. These include: * Repeat of screening tests * Questionnaires * Exercise test * Resting energy expenditure test: Participants fast overnight before the test. They lie on their back under a canopy for a half hour. * Body composition test: This is done with a dual energy x-ray absorptiometry (DXA) scan. * Pelvic ultrasound * For two full-day visits, an IV is inserted into an arm vein. The IV takes a blood sample every 10 minutes for 8 hours. Participants will keep logs: * Menstrual cycle log * Diet log for three 4-day cycles Participants will receive test kits to complete at home: * Daily blood and urine sample * Ovulation Participants will take a daily iron supplement. They will wear a wristband that monitors activity 24 hours a day. Participants will stick to a special diet for two 5-day periods of time. They will complete two 4-day exercise programs....
Vitamin D is present in food either naturally or by fortification and included in nutritional supplements. It is also synthesized photochemically by the skin from ultraviolet B radiation. Vitamin D synthesis varies by season and with latitude as well as according to intensity of skin pigmentation. Recent research in the United States found lower circulating levels of 25 (OH) D, the primary indicator of vitamin D status, among minority women who were either pregnant or in their reproductive years. The extent to which maternal vitamin D has an influence on the course and outcome of human pregnancy remains to be more completely studied. We propose to use the HPLC method to assay cholecaliferol (vitamin D3) and ergocalciferol (vitamin D2) to assess maternal vitamin D status. This will be accomplished by analyzing existing fasting samples and data derived from the 2001-2006 cohort (N=1141) of young, low income minority gravidae from Camden, New Jersey to determine: 1. The prognostic importance of maternal vitamin D status for birth weight, gestation duration and poor pregnancy outcomes (low birth weight, preterm delivery, fetal growth restriction). 2. The relation of maternal vitamin D status to important complications of pregnancy (gestational diabetes and pre-eclampsia). 3. The relationship of maternal vitamin D status to maternal diet and supplement use, season of year, ethnicity, overweight/obesity, and other maternal characteristics.
Background: Endocrine disorders occur when the glands that make hormones do not work properly. Hormones levels that are too high or too low can cause problems such as late or early puberty, irregular periods, and infertility. Environmental factors - including pollution; chemical exposure at home and work; foods; medicines; and sleep habits - may cause problems with the endocrine and reproductive systems. Objective: To learn how environmental factors may affect the endocrine and reproductive systems. Eligibility: Males or females, referring to sex assigned at birth, aged 8 years and older; they must have hypogonadism, infertility, or other reproductive disorders. Design: Adult participants will have 4 to 5 visits in 5 years. Children may have up to 12 visits; they may remain in the study up to the age of 23. Most visits will be less than 3 hours. Participants will be screened. They will have a physical exam. They will have blood and urine tests. They will complete questionnaires; they will answer questions about their diet, health, and other topics. Some may be referred for additional tests, such as imaging scans and semen analysis. Specific tests conducted during study visits will vary, depending on the participant s diagnosis. In addition to repeated blood and urine tests, these may include: Body composition measure: Participants will sit in a pod-shaped machine for about 6 minutes. The machines measures the air inside the capsule to record body fat and breathing volume. Resting energy expenditure test: Participants will lie down with a clear dome placed over their head. They will breathe quietly for 30 minutes. This test measures the number of calories their body burns at rest. ...
This study will entail provision of ulipristal acetate (UPA) for emergency contraception (EC) in the postpartum period for patients who have not chosen to initiate a highly effective form of contraception and study the use of EC overall as well as with regards to participants' perception of reproductive autonomy. The investigators hypothesize that providing an advance supply of EC will increase use and decrease barriers to use. Additionally, the investigators hypothesize that, with thorough EC counseling, participants will develop an increased knowledge base of EC. With increased use and knowledge, the investigators hypothesize that participants will experience greater reproductive autonomy over their contraceptive decisions.
This study evaluates the effects of estrogen and progesterone on mood, the stress response, and brain function in healthy women. The purpose of this study is to evaluate how low levels of estrogen and progesterone (that occur during treatment with leuprolide acetate) compare to menstrual cycle levels of estrogen and progesterone (given during individual months of hormone add-back) on a variety of physiologic measures (brain imaging, stress testing, etc.) in healthy volunteer women without PMS. This study will investigate effects of reproductive hormones by temporarily stopping the menstrual cycle with leuprolide acetate and then giving, in sequence, the menstrual cycle hormones progesterone and estrogen. Tests (such as brain imaging or stress testing, etc.) will be performed during the different hormonal conditions (low estrogen and progesterone, progesterone add-back, estrogen add-back). The results of these studies will be compared between women without PMS and women with PMS (see also protocol 90-M-0088). At study entry, participants will undergo a physical examination. Blood, urine, and pregnancy tests will be performed. Cognitive functioning and stress response will be evaluated during the study along with brain imaging and genetic studies.
This research study investigates whether male-level exogenous androgens inhibit the reproductive neuroendocrine axis in otherwise healthy (non-PCOS) females.
The purpose of this study is to understand the direct effects of cannabis on male reproductive functions. The investigators plan to conduct a double-blind, placebo-controlled clinical trial to examine both the chronic and acute effects of cannabis use on male reproductive functions. Specifically, the investigators will examine the dose-dependent effects of acute cannabis use on male reproductive parameters, including sperm counts, motility, morphology, and testosterone levels, as well as sperm epimutations. Participants \[cannabis users will be randomly assigned to 1) non-vaping, 2) placebo (vaping without cannabis), and 2 doses of cannabis, 3) 20 and 4) 40mg of THC in cannabis flower obtained from the NIDA drug supply\], and 5) non-cannabis users (naïve control, no cannabis or placebo exposure). Participants will provide surveys (cannabis use and sexual functioning and satisfaction etc.), peripheral blood, and semen.

The investigators are testing the hypothesis that two ounces of whole-shelled walnuts/day added to the diet of men seeking care for infertility will beneficially affect sperm parameters and fertility. The investigators will compare the walnut intervention to the commonly suggested recommendation of adding an OTC multivitamin supplement to the diet.
The United States has the highest prevalence of obesity among all countries surveyed in 2012 by the Organization for Economic Cooperation and Development. Maternal obesity is linked with anovulation, menstrual cycle abnormalities, subfertility, fetal loss, obstetrical complications and congenital anomalies. Changes in reproductive hormones and diminished oocyte quality have also been demonstrated. A gap of knowledge exists as the mechanisms underlying these harmful effects are poorly understood and no specific treatments exist. This proposal will test the hypothesis that dietary omega-3 fatty acids (FA) will improve the output of hypothalamicpituitary- ovarian axis in obese women. The investigators will perform paired assessments before and after supplementation in 10 obese and 10 normal weight women. To test the pituitary and hypothalamic output, the investigators will examine the luteinizing hormone (LH) and follicle-stimulating hormone (FSH) responsiveness during frequent blood sampling. To test the corpus luteum function, the investigators will examine urinary reproductive hormones (E1c, estrone conjugates, and pregnanediol glucuronide (Pdg)) over an entire menstrual cycle. The investigators ultimate goal is to collect preliminary data for an adequately powered randomized control trial.
This is a study to determine whether a low calorie diet using meal replacement shakes compared to current counseling about diet, followed by 3 cycles of clomiphene citrate (if needed) will result in: 1) improvements in ability to ovulate and achieve pregnancy either spontaneously or during 3 clomiphene citrate cycles 2) greater weight loss with reductions in waist and hip circumferences and improvements in hormones that are involved in allowing pregnancy to occur and hormones that are involved in metabolism, such as insulin and glucose (sugar) 3) improvements in other health conditions such as blood pressure, and emotional and physical well-being. Women eligible to participate will be between the ages of 18-35 with a BMI (ratio of weight in kg divided by height in m2) of ≥ 35≤45 kg/m2 who are seeking help for anovulatory infertility including women with a diagnosis of polycystic ovarian syndrome (PCOS).
This is a study on a population of flight attendants who were exposed to occupational secondhand tobacco smoke (SHS). This research will examine associations between flight attendant SHS exposure and development of respiratory illnesses, reproductive problems, and cardiovascular diseases.
The rapidity with which progesterone slows LH (and by inference GnRH) pulse frequency in women is unclear. The investigators hypothesize that progesterone slows LH pulse frequency within 10 hours. The investigators propose to assess this further with a randomized, cross-over, placebo-controlled study. Regularly cycling women without hyperandrogenism will be admitted to the Clinical Research Unit on cycle day 5-9 (mid-follicular phase) for a 10 hour frequent sampling study to observe LH, FSH, estradiol, progesterone, and testosterone. Either oral micronized progesterone suspension or placebo will be administered at 0900 h. During a subsequent menstrual cycle, subjects will undergo another study identical to the first except that oral progesterone will be exchanged for placebo or vice versa in accordance with a crossover design.
Polycystic ovary syndrome (PCOS) is the most common reproductive disorder in women of reproductive age and despite decades of research the etiology the disorder is not known. The characteristic hyperandrogenism and anovulation is associated with abnormal neuroendocrine function and insulin resistance. Obesity is a common correlated phenotype of Polycystic ovary syndrome and weight gain worsens the reproductive and metabolic complications. Currently there is no evidence-based treatment plan for infertility in Polycystic ovary syndrome; yet weight loss by dietary restriction and regular exercise are strongly advocated. Weight loss and increased insulin sensitivity appear to drive improvements in reproductive outcomes in women with Polycystic ovary syndrome; however, the mechanism connecting these changes with the reproductive axis is not fully understood.

The proposed study involves experimentally manipulating reproductive hormones in nonpregnant, euthymic women to create a scaled down version of the changes that occur during pregnancy and the postpartum period. This endocrine manipulation paradigm, which the investigators have shown provokes irritability in past studies, will be used to examine the neurocircuitry underlying irritability under baseline and hormone challenge conditions among women who are hormone sensitive (HS+; n=15) and non-hormone sensitive (HS-; n=15). The long-term goal of this research is to advance understanding of the neural systems underlying both the triggering of and susceptibility to irritability in women. The objective of the current project is to examine whether HS+ show differences in the behavioral activation system relative to HS- under baseline and hormone challenge conditions using functional magnetic resonance imaging (fMRI) and behavioral tests.
