This study found that natural hormone fluctuations in women, including estradiol and testosterone, did not significantly correlate with changes in prosocial behavior. Within-subject analyses are crucial for understanding hormone-behavior links.
Area of Science:
- Social Psychology
- Endocrinology
- Behavioral Neuroscience
Background:
- Prosocial behavior is vital for societal function.
- Exogenous hormone administration affects prosociality, but natural hormonal fluctuations' role in women is unclear.
Purpose of the Study:
- To investigate the relationship between natural salivary steroid hormone levels and women's prosociality.
- To examine estradiol, progesterone, and testosterone's influence on prosocial tendencies in various contexts.
Main Methods:
- Collected weekly salivary hormone samples (estradiol, progesterone, testosterone) from participants over five weeks.
- Assessed prosociality using behavioral tasks (Charitable Donation, Social Value Orientation, Social Discounting) and a self-report questionnaire (Prosocial Tendencies Measure).
- Conducted within-subject analyses to track individual hormonal and behavioral fluctuations.
Main Results:
- Found minimal evidence that natural changes in estradiol, progesterone, estradiol-to-progesterone ratio, or testosterone correlated with women's prosociality.
- No significant tracking observed between hormonal fluctuations and prosocial behavior across different measures.
Conclusions:
- Natural hormonal fluctuations do not appear to significantly modulate women's prosocial behavior in the studied contexts.
- Emphasizes the necessity of within-subject designs for accurately assessing hormone-behavior relationships.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
