Sex-specific aging in animals: Perspective and future directions

Area of Science:

• Gerontology
• Comparative Biology
• Sexology

Background:

• Sex differences in aging, including lifespan and age-associated decline, are observed across diverse animal species.
• The causes and molecular underpinnings of these sex differences in aging remain largely unknown.
• The specific roles of sex determination and other sex-specific factors in aging are understudied.

Purpose of the Study:

• To explore hypotheses regarding the origins of sex differences in aging.
• To investigate the relationship between genomic, morphological, and environmental factors and sex differences in aging.
• To propose future research directions and experimental designs in the field of sex differences in aging.

Main Methods:

• Comparative and interdisciplinary approach.
• Review and synthesis of existing literature on sex differences in aging.
• Exploration of genomic, morphological, and environmental factors.

Main Results:

• Sex differences in aging manifest diversely across species, with varied lifespans and aging rates between sexes.
• Hypotheses regarding the causes of sex differences in aging are explored, considering genetic, hormonal, and environmental influences.
• The study highlights the need for further research into the molecular mechanisms driving these differences.

Conclusions:

• Understanding the causes of sex differences in aging requires an interdisciplinary approach.
• Future research should focus on elucidating the molecular drivers and the role of sex determination in aging.
• Recommendations for experimental designs are provided to advance the study of sex differences in aging.
