Area of Science:

  • Reproductive biology
  • Genetics
  • Human and mouse models

Background:

  • Fertility is crucial for human reproduction.
  • Understanding the genetic basis of fertility is essential for diagnosing and treating infertility.

Purpose of the Study:

  • To review current literature on genes affecting human and mouse fertility.
  • To focus on genes involved in spermatogenesis and oogenesis, including Y-chromosome genes.
  • To incorporate findings from mouse models with deleted genes.

Main Methods:

  • Comprehensive literature review.
  • Selection of key articles focusing on gametogenesis.
  • Inclusion of studies on Y-chromosome genes and transgenic mouse models.

Main Results:

  • Y-chromosome gene families are implicated in male infertility, though the precise mechanisms remain unclear.
  • Mouse genes involved in DNA repair and damage monitoring significantly impact gametogenesis, particularly during meiosis.
  • Several genes are exclusively involved in gametogenesis, with their functions becoming increasingly understood.

Conclusions:

  • Numerous genes are essential for gametogenesis, with some functions now being elucidated.
  • Mouse models provide valuable insights into human reproductive diseases.
  • Further research is needed to fully understand the genetic underpinnings of fertility.
