Female sexual behavior: fluctuations during the menstrual cycle

Area of Science:

• Reproductive Endocrinology
• Human Sexuality
• Behavioral Science

Background:

• Female sexuality is complex and influenced by various factors.
• The menstrual cycle involves significant hormonal fluctuations.
• Understanding these fluctuations' impact on sexual behavior is crucial.

Purpose of the Study:

• To investigate the influence of menstrual cycle phase on female sexuality.
• To analyze patterns in sexual behavior across different cycle phases.

Main Methods:

• Longitudinal prospective study of 69 normally cycling women.
• Daily monitoring of sexual behavior (heterosexual and autosexual) and basal body temperature.
• Analysis of five menstrual cycle phases (menstrual, postmenstrual, ovulatory, luteal, premenstrual) using repeated measures ANOVA.

Main Results:

• Significant cyclic fluctuations in sexual behavior were observed.
• Both female- and male-initiated sexual activities peaked during the ovulatory phase.
• Increased sexual arousal and pleasure were reported from menses to premenstruum.

Conclusions:

• Menstrual cycle phase significantly influences female sexual behavior.
• Hormonal fluctuations and cognitive factors associated with the menstrual cycle likely play a role.
• Findings suggest a biological basis for cyclical changes in female sexuality.
