Evaluation of an Online Intervention for Female Sexual Dysfunction (FELYCIA)

August 18, 2025 updated by: Gaia AG

Evaluation of an Online Intervention for Female Sexual Dysfunction: Randomized Controlled Trial

In this randomized controlled clinical trial, 250 participants with female sexual dysfunction will be investigated regarding the effectiveness of an online intervention for improving sexual function, the unguided online intervention mylovia. Inclusion criteria are: female sex and female gender, age ≥18, diagnosed sexual dysfunction (ICD-11: HA00, HA01, HA02) or sexual pain disorder (ICD-11: HA20), low sexual functioning (<27 on the Female Sexual Function Index; FSFI), sufficient German skills, and consent to participation. Exclusion criteria are: biological, psychological or social factors that might interfere with study participation, and use of another digital intervention for sexual problems. Participants will be randomized and allocated to either an intervention group, receiving access to mylovia in addition to treatment as usual (TAU), or a control group, receiving information material about treatment and counseling options in addition to TAU. Primary endpoint will be sexual functioning assessed via FSFI, with three months post-allocation being the primary time point for assessment of effectiveness. Six months post allocation will be used as a timepoint for follow-up assessment of endpoints. Secondary endpoints will be sexual desire, sexual satisfaction, sexual pain, and general psychopathology.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
252

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • female sex
  • female gender
  • age ≥ 18 years
  • diagnosis of sexual dysfunction (ICD-11: HA00, HA01, HA02) or sexual pain disorder (ICD-11: HA20), diagnosed via the DISEX-F interview
  • Sexual function score (cut-off) of <27 on the FSFI
  • consent to participation
  • sufficient knowledge of the German language

Exclusion Criteria:

  • Use of another digital intervention for sexual problems

In general, given that sexual dysfunction is a biopsychosocial phenomenon, mylovia is hypothesized to help women irrespective of the disorder's etiology (i.e., biological, psychological, or social). However, if one of the domains is extremely compromised, mylovia might not be expedient. Therefore, a clinical assessment of factors that might interfere with study assessment will be conducted, with the following additional exclusion criteria:

  • Biological factors that might interfere with study participation (e.g., cancer, multiple sclerosis)
  • Psychological factors that might interfere with study participation (e.g., schizophrenia, bipolar disorder, borderline personality disorder, eating disorder, post-traumatic stress disorder, severe depression, suicidality, substance use disorder)
  • Social factors that might interfere with study participation (e.g. severe partnership problems)

  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: mylovia + TAU

Participants allocated to the intervention group will receive access to mylovia in addition to treatment as usual (TAU).

mylovia is a digital health application designed for women with sexual dysfunction, accessible through a web browser. The application focuses on treatment methods derived from cognitive behavioral therapy (CBT). Topics addressed by mylovia are psychoeducation, relaxation and mindfulness exercises, strategies to improve self-esteem, development of passionate attitudes and situations, dealing with differences in desire in a relationship, and sensate focus exercises.

The program operates through interactive "dialogues", which are accompanied by illustrations, audio recordings, motivational text messages, worksheets, and summaries. Users are also encouraged to regularly complete short questionnaires to monitor their complaints. Once registered, the program remains accessible for 180 days.
Behavioral: mylovia
Participants will receive access to the digital health intervention mylovia in addition to TAU.
No Intervention: information material + TAU
Participants allocated to the control group will receive access to information material about treatment and counseling options in addition to treatment as usual (TAU).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: 3 months
Female Sexual Function Index (FSFI). Total score ranging from 2-36; higher scores mean better sexual function (better outcome).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sexual desire
Time Frame: 3 months, 6 months
Sexual Interest and Desire Inventory - Female - Self-Report (SIDI-F-SR). Total score ranging from 0-51; higher scores mean higher levels of sexual desire (better outcome).

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants.
