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.
Maternal-fetal medicine (MFM) is the branch of obstetrics which focuses mainly on the medical and surgical management of high-risk pregnancies that includes monitoring and treatment including comprehensive ultrasound, chorionic villus sampling, genetic amniocentesis, and fetal surgery or treatment. Obstetricians who practice maternal-fetal medicine are also known as perinatologists.
Just as there was a shift from viewing disease as a state to thinking of it as a process, the same shift happened in definitions of health. Again, the WHO played a leading role when it fostered the development of the health promotion movement in the 1980s. This brought in a new conception of health, not as a state, but in dynamic terms of resiliency, in other words, as "a resource for living". 1984 WHO revised the definition of health defined it as "the extent to which an individual or group is able to realize aspirations and satisfy needs and to change or cope with the environment. Health is a resource for everyday life, not the objective of living; it is a positive concept, emphasizing social and personal resources, as well as physical capacities".[10] Thus, health referred to the ability to maintain homeostasis and recover from insults. Mental, intellectual, emotional and social health referred to a person's ability to handle stress, to acquire skills, to maintain relationships, all of which form resources for resiliency and independent living.[9] This opens up many possibilities for health to be taught, strengthened and learned.
