Oogenesis02:07

Oogenesis

64.4K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Meiosis vs. Mitosis02:57

Meiosis vs. Mitosis

58.3K
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

Applications of Life Tables01:22

Applications of Life Tables

125
Life tables are versatile across various fields, providing a quantitative basis for analyzing mortality and survival rates. Whether used by demographers, actuaries, epidemiologists, or sociologists, life tables offer valuable insights into the dynamics of life and death, facilitating informed decisions in public health, insurance, conservation, and beyond. Their broad applicability highlights the interconnectedness of demographic data with practical outcomes in everyday life and strategic...

Nondisjunction01:21

Nondisjunction

4.1K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

Menopause01:28

Menopause

252
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Life Tables01:22

Life Tables

199
A life table is a statistical tool that summarizes the mortality and survival patterns of a population, providing detailed insights into the likelihood of survival or death across different age intervals within a cohort. By organizing data on survival probabilities and mortality rates, life tables offer a clear snapshot of population dynamics over time. They are extensively used in demography, public health, actuarial science, and ecology to analyze life expectancy, design health interventions,...

Area of Science:

  • Demography
  • Public Health
  • Reproductive Health

Background:

  • Advanced maternal age is linked to increased pregnancy complication risks.
  • Greece has observed evolving trends in childbirth age over decades.

Purpose of the Study:

  • To analyze long-term trends in maternal age at childbirth in Greece.
  • To provide a comprehensive analysis of live birth distribution by maternal age over time.

Main Methods:

  • Analysis of 8,208,255 live births in Greece (1956-2023).
  • Maternal age categorized into six groups (<20, 20-24, 25-29, 30-34, 35-39, ≥40).
  • Joinpoint regression analysis used to evaluate temporal shifts and trends.

Main Results:

  • Mean maternal age at childbirth rose from 26.1 years (1983-84) to 32.1 years (2023).
  • The primary childbearing age group shifted from 20-24 to 30-34 years since 2005.
  • Births to mothers ≥40 increased significantly, reaching 10.69% in 2023.

Conclusions:

  • Greece shows a significant increase in maternal age since the 1980s.
  • Trends indicate a shift towards older mothers, including a dramatic rise in births to women aged 40+.
  • These demographic shifts present challenges for national perinatal health outcomes.
