Study Notes

Basic Concepts and Statistics of Infertility

Fertility is closely linked to reproductive function
Structural or functional abnormalities in the reproductive system can impair reproductive capacity
Reproductive problems can lead to infertility

Demographic Terms for Fertility

Fertility: The natural ability to produce offspring
Fecundity: The potential output of reproduction, measured by the number of gametes, seeds, etc.
Fertility Rate (TFR): The average number of children born or expected to be born to a woman in her lifetime, considering current age-specific fertility rates
Birth Rate: The total number of live births per 1,000 people in a population in a given year or period.

Statistics on Infertility

Globally, over 186 million people suffer from infertility
Infertility affects 8-12% of couples of reproductive age worldwide
Infertility in developing countries is higher—one in four couples versus one in seven in developed nations
Fertility declines with age, more steeply in women after age 37 and in men after 40
Lifestyle and environmental factors contribute to infertility, especially with increasing age

Fertility and Population Dynamics

Fertility studies inform national/global policies impacting reproductive healthcare, family planning, child development, and support for aging populations
Accurate understanding of population dynamics is needed for policy decisions and resource allocation
Population dynamics is the branch of life sciences studying population size, age structure, and trends, and the processes influencing them

Clinical Terminology for Fertility

Fertility: The ability to achieve a clinical pregnancy in 12 months of regular intercourse without contraception
Subfertility: Reduced fertility, characterized by a prolonged time to conception
Infertility: Inability to conceive a child after 12 months of regular intercourse without contraception
Sterility: Complete inability to conceive

Types of Infertility

Primary Infertility: Couples who have not conceived after one year of regular intercourse without contraception
Secondary Infertility: Couples who have previously conceived but are now unable to conceive

Factors Influencing Infertility

Hormones, gametes, gonads, reproductive ducts, and external genitalia are examined in infertility evaluations
Any factor that affects these components negatively impacts fertility
