Research Case Studies

Case Study A (2019–2021): "Libido and Sleep Quality Study"
Over 1,800 participants analyzed.
Result: Individuals with sleep fragmentation showed a 32% reduction in spontaneous desire frequency.
Quote: “Libido is one of the most sleep-sensitive psychological systems. Even mild sleep disruption can significantly alter desire expression.”
Case Study B (2020–2022): "Stress-Driven Desire Suppression in Couples"
850 couples studied over 18 months.
Result: High chronic stress predicted desire discrepancy in 67% of relationships.
Quote: “The most common cause of mismatched desire is not mismatched personalities, but mismatched stress loads.”
Case Study C (2017–2019): "Hormonal Predictors of Low Desire in Men"
400 male participants, including longitudinal bloodwork.
Result: Combined low dopamine markers and mild depression increased risk of chronic low libido by 54%.
