Testicular Biopsy

A diagnostic procedure used to identify male infertility and azoospermia.

Imaging Tests (Infertility)

Pelvic/scrotal ultrasound or MRI to help find problems with reproductive organs.

Physical Exam (Infertility)

Checking the genitals, and sometimes breasts and pelvis to help find infertility causes.

Hormonal Tests (Infertility)

Tests for hormones like FSH, testosterone, or progesterone to evaluate hormonal imbalances that affect fertility.

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
