4. Infertility affects about 6% of married women ages 15-44 years in the U.S. Also, about 12% of women 15 – 44 years of age in the U.S. have difficulty getting pregnant or carrying a pregnancy to term, regardless of marital status. Infertility is defined as not being able to get pregnant after one year of unprotected sex. Several things increase a woman’s risk of infertility, including age, smoking, excessive alcohol use, extreme weight gain or loss, some untreated sexually transmitted diseases, or excessive physical or emotional stress that results in the absence of a menstrual period.
Because of the current competitive environment, health care providers (hospitals, HMOs, physicians, and others) are constantly searching for better products and better means for delivering them. The health care product is often loosely defined as a service. The authors develop a more precise definition of the health care product, product line, and product mix. A bundle-of-elements concept is presented for the health care product. These conceptualizations help to address how health care providers can segment their market and position, promote, and price their products. Though the authors focus on hospitals, the concepts and procedures developed are applicable to other health care organizations.

Systematic activities to prevent or cure health problems and promote good health in humans are undertaken by health care providers. Applications with regard to animal health are covered by the veterinary sciences. The term "healthy" is also widely used in the context of many types of non-living organizations and their impacts for the benefit of humans, such as in the sense of healthy communities, healthy cities or healthy environments. In addition to health care interventions and a person's surroundings, a number of other factors are known to influence the health status of individuals, including their background, lifestyle, and economic, social conditions and spirituality; these are referred to as "determinants of health." Studies have shown that high levels of stress can affect human health.[15]
