In the United States, infertility affects 1.5 million couples. Many couples seek assisted reproductive technology (ART) for infertility. In the United States in 2010, 147,260 in vitro fertilization (IVF) procedures were carried out, with 47,090 live births resulting. In 2013 these numbers had increased to 160,521 and 53,252. However, about a half of IVF pregnancies result in multiple-birth deliveries, which in turn are associated with an increase in both morbidity and mortality of the mother and the infant. Causes for this include increased maternal blood pressure, premature birth and low birth weight. In addition, more women are waiting longer to conceive and seeking ART.
Young adults. Teen girls and young women usually need more calories than when they were younger, to support their growing and developing bodies. After about age 25, a woman’s resting metabolism (the number of calories her body needs to sustain itself at rest) goes down. To maintain a healthy weight after age 25, women need to gradually reduce their calories and increase their physical activity.
The average woman should get 10 to 35 percent of her daily calories from protein. Protein helps prevent muscle tissue from breaking down and repairs body tissues. Sources of animal proteins include meat, fish, poultry, eggs, milk and cheese. Vegetable proteins include dried beans and peas, peanut butter, nuts, bread and cereal. (A three-ounce serving of cooked chicken contains about 21 grams of protein.)
Salt, caffeine and alcohol intake may interfere with the balance of calcium in the body by affecting the absorption of calcium and increasing the amount lost in the urine. Moderate alcohol intake (one to two standard drinks per day) and moderate tea, coffee and caffeine-containing drinks (no more than six cups per day) are recommended. Avoid adding salt at the table and in cooking
Women need more of this mineral because they lose an average of 15 to 20 milligrams of iron each month during menstruation. Without enough iron, iron deficiency anemia can develop and cause symptoms that include fatigue and headaches. After menopause, body iron generally increases. Therefore, iron deficiency in women older than 50 years of age may indicate blood loss from another source and should be checked by a physician.
Women's life expectancy is greater than that of men, and they have lower death rates throughout life, regardless of race and geographic region. Historically though, women had higher rates of mortality, primarily from maternal deaths (death in childbirth). In industrialised countries, particularly the most advanced, the gender gap narrowed and was reversed following the industrial revolution.  Despite these differences, in many areas of health, women experience earlier and more severe disease, and experience poorer outcomes.
