About this study

Official title: The Effects of Oral Supplementation With Geranylgeraniol (GG) Sourced From Annatto on Sexual Health in Males and Females

The purpose of this study will be to examine the effectiveness of Geranylgeraniol supplementation on sexual health function in males and females following an 8-week dose escalation intervention. The study will be carried out in a randomized, double-blind, placebo-controlled, parallel manner. Participants will be stratified into quartiles based on their scores on the Derogatis Interview for Sexual Functioning during screening and prior to baseline testing. Participants from each quartile will be randomly divided by into treatment or placebo conditions.

Following randomization, participants will be baseline assessed on their sexual health function using a variety of questionnaires, body composition using a whole body Dual Energy X-Ray Absorptiometry scan, blood chemistry panel, and grip strength using a hand-held dynamometer. Following baseline testing, participants will undergo 8 weeks of supplementation of their respective supplement condition. Participants will be instructed to consume two servings a day (150mg total per day) from weeks 1-4. Subject will return to the study site after 4 weeks to reassess the above-mentioned parameters. Participants will then undergo a dose escalation and be instructed to consume two servings a day (300mg total per day) from week 5-8. Sexual health questionnaires and assessments of body composition, blood chemistry, and grip strength will be conducted following the week 8 to conclude the study.

Questions about this trial

What is this clinical trial studying?

A study testing GG sourced from Annatto in people with Sexual Health and Libido, run by Applied Science & Performance Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 29 Dec 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Changes in Overall Sexual Function (time frame: Week 0, 4 and 8). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Dec 2022.
