Behavioral and biological determinants of fecundability

Area of Science:

• Reproductive Health
• Human Biology
• Behavioral Science

Background:

• Fecundability, the ability to conceive, is influenced by numerous behavioral and physiological factors.
• Existing research has often overlooked critical male factors and lifestyle influences on reproductive success.

Purpose of the Study:

• To discuss key behavioral and physiological determinants of fecundability.
• To highlight the significance of under-examined factors, particularly male attributes and lifestyle choices.
• To identify potential interactions between behavioral and biological determinants of fecundability.

Main Methods:

• Literature review and synthesis of existing research on fecundability determinants.
• Discussion of behavioral factors including sexual behavior, contraception use, nutrition, alcohol consumption, exercise, smoking, and stress.
• Exploration of physiological factors, including hormonal profiles and sperm function.

Main Results:

• Male factors, including sexual behavior and hormonal profiles affecting sperm function, are crucial but often under-discussed determinants of fecundability.
• Lifestyle factors such as nutrition, alcohol, exercise, smoking, and stress significantly impact fecundability.
• Identified potential interactions between behavioral and biological factors influencing reproductive capacity.

Conclusions:

• A comprehensive understanding of fecundability requires integrating male factors and lifestyle influences.
• Future research should combine empirical studies and modeling to elucidate complex interactions affecting reproductive health.
• Addressing both male and female factors, alongside lifestyle, is essential for improving fertility outcomes.
