Women who report feeling stressed early in their monthly cycle were more likely than those who were less stressed to report more pronounced symptoms before and during menstruation, according to a study by researchers at the National Institutes of Health and other institutions. The association raises the possibility that feeling stressed in the weeks before menstruation could worsen the symptoms typically associated with premenstrual syndrome and menstruation.

NIH Study Indicates Stress May Delay Women Getting Pregnant
A study by researchers at the National Institutes of Health and the University of Oxford supports the widespread belief that stress may reduce a woman's chance of becoming pregnant. The study is the first of its kind to document, among women without a history of fertility problems, an association between high levels of a substance indicative of stress and a reduced chance of becoming pregnant.
Women's Cholesterol Levels Vary with Phase of Menstrual Cycle
National Institutes of Health researchers have shown that women's cholesterol levels correspond with monthly changes in estrogen levels. This natural variation, they suggest, might indicate a need to take into account the phases of a woman's monthly cycle before evaluating her cholesterol measures. On average, the total cholesterol level of the women in the study varied 19 percent over the course of the menstrual cycle.
NIH-Funded Researchers Generate Mature Egg Cells From Early Ovarian Follicles
Researchers supported by the National Institutes of Health have for the first time activated mouse egg cells at the earliest stage of their development and brought them to maturity. In a related experiment, the researchers replicated the finding by also bringing human eggs to maturity in the laboratory.
Recovery Act Funds Key Reproductive Health Research
Millions of Americans with reproductive health disorders stand to benefit from new research funded by the National Institutes of Health. With funds from the American Recovery and Reinvestment Act, the National Institutes of Health today announced grants totaling nearly $60 million for research into disorders that impair fertility, cut short a woman's reproductive years, and often cause intense pain.
New Intramural Report Available
The Division’s research programs address topics ranging from molecular and cellular biology, genetics, and endocrine and genetic disorders, to physical biology, neurosciences, immunology, reproduction, and behavioral research. Its projects are organized around the theme of the orchestration of life by molecular messengers.
NIH Study Confirms Location of Stem Cells Near Cartilage-Rich Regions in Bones
Working with mice, a team of researchers has pinpointed the location of bone generating stem cells in the spine, at the ends of shins, and in other bones. The team also has identified factors that control the stem cells' growth. The research was conducted at the National Institutes of Health and other institutions.
Risk of Newborn Heart Defects Increases with Maternal Obesity
The more obese a woman is when she becomes pregnant, the greater the likelihood that she will give birth to an infant with a congenital heart defect, according to a study conducted by researchers at the National Institutes of Health and the New York state Department of Health.
Vitamin C and E Supplements Do Not Reduce Risk for Blood Pressure Disorders of Pregnancy
Taking vitamin C and E supplements starting in early pregnancy does not reduce the risk for the hypertensive disorders and their complications that occur during pregnancy, according to a study by a National Institutes of Health research network.
Study Finds Link Between Preeclampsia & Reduced Thyroid Function
Women who experience preeclampsia, a serious complication of pregnancy, may have an increased risk for reduced thyroid functioning later in life, report a team of researchers from the National Institutes of Health and other institutions.
NIH-Funded Researchers Transform Embryonic Stem Cells into Human Germa Cells
Researchers funded in part by the National Institutes of Health have discovered how to transform human embryonic stem cells into germ cells, the embryonic cells that ultimately give rise to sperm and eggs. The advance will allow researchers to observe human germ cells--previously inaccessible--in laboratory dishes.
Treating Even Mild Gestational Diabetes Reduces Birth Complications
A National Institutes of Health network study provided the first conclusive evidence that treating pregnant women who have even the mildest form of gestational diabetes can reduce the risk of common birth complications among infants, as well as blood pressure disorders among mothers.
New Technique Could Eliminate Inherited Mitochondrial Disease
Researchers funded by the National Institutes of Health have developed an experimental technique with the potential to prevent a class of hereditary disorders passed on from mother to child. The technique, as yet conducted only in nonhuman primates,involves transferring the hereditary material from one female's egg into another female's egg from which the hereditary material has been removed.
U.S. Updates Clinical Guidelines for Prevention & Treatment of Opportunistic Infections among HIV-Exposed & HIV-Infected Children
New guidelines to assist health care workers in preventing and treating the secondary infections that can afflict U.S. children exposed to, or infected with, HIV, were published by the National Institutes of Health and the Centers for Disease Control and Prevention.
New Technique Could Sustain Cancer Patients' Fertility
Researchers funded by the National Institutes of Health have completed a critical first step in the eventual development of a technique to retain fertility in women with cancer who require treatments that might otherwise make them unable to have children.
NIH Podcast Advises Women On How to Achieve a Healthy Pregnancy
Women can increase their chances for a healthy pregnancy by eating right, exercising, not smoking, and getting early medical care, says a podcast featuring a National Institutes of Health obstetrician who oversees research on pregnancy and birth.
Researchers Identify Key Proteins Needed for Ovulation
Researchers from the National Institutes of Health and other institutions have identified in mice two proteins essential for ovulation to take place.
Plan Offers Guidance For Evaluating Menopause-Like Condition in Girls & Young Women
A comprehensive plan to help health care professionals diagnose and treat primary ovarian insufficiency--a menopause-like condition affecting girls and young women that may occur years before normal menopause is expected--has been developed by a scientist at the National Institutes of Health.
Roughly One Quarter of U.S. Women Affected by Pelvic Floor Disorders
Nearly 24 percent of U.S. women are affected with one or more pelvic floor disorders, report researchers funded by the National Institutes of Health. Their analysis is the first to document in a nationally representative sample the extent of pelvic floor disorders, a cluster of health problems that causes physical discomfort and limits activity.
Common Treatment to Delay Labor Decreases Preterm Infants' Risk for Cerebral Palsy
Preterm infants born to mothers receiving intravenous magnesium sulfate--a common treatment to delay labor--are less likely to develop cerebral palsy than are preterm infants whose mothers do not receive it, report researchers in a large National Institutes of Health research network.
