Primary Premature Ejaculation Genetics

March 12, 2025 updated by: Institut National de la Santé Et de la Recherche Médicale, France

Identification Des Bases Moléculaires De L'éjaculation Prématurée Primaire

The main objective of our study is to identify the first genetic etiology of primary Premature Ejaculation (PE). We will test and evaluate the existence of genetic determinism conferring susceptibility to a life-long syndrome (primary premature ejaculation) in some patients. To this end, we plan to establish a collection of biological samples and a database of patients with this extreme syndrome, which we will analyze by Genome Wide analysis. This will lead to improvements in the biological understanding, the "knowledge" of physicians of the disease, and should improve the patients' quality of life. Not all PE cases have the same physiopathology and treatment efficiency, which depend on the specific mechanism involved in the clinical context. Our work will make it possible to develop new therapeutic approaches suitable for a large proportion of individuals presenting PE. This integrative approach combining researchers, patients and ethics committees will facilitate profound reflection, promoting the creation of suitable structures capable of receiving patients for appropriate consultations. This unique study of PE should also favor industrial partnerships.

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.

Detailed Description

2.1 Main Objective

  • To identify the molecular basis of primary premature ejaculation (PPE) in humans for the development of new adapted therapy.
  • Check and confirm the genetic hypothesis of PPE to fill the void of genetic knowledge about this syndrome.
  • Improve knowledge of physicians on this disease to increase the comfort of life of patients.

2.2 Secondary Objectives

  • Provide the basis for new therapeutic approaches.
  • Expanded knowledge of the aetiology of PE and allow better management of patients.
  • Develop strategies to prevent the consequences, sometimes severe , of this condition on the intimate, personal, social and professional life of these patients. Because all the PE do not have the same pathophysiology and treatment success depends on its relevance to the specific mechanism of the clinical form concerned.
  • Increase the comfort of life of the patients.
  • Eliminate public prejudice based on misconceptions.

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.

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
Number of subjects with genetic mutations of susceptibility to primary PE
Time Frame: 4 years
We will perform WES (Whole Exome Sequencing) to identify shared defective genes in 20 patients. In case of genetic uniformity and of a genetically homogeneous recruitment, we hope to highlight such a gene in several individuals. As primary PE are very rare, this group should have defective genes at much higher frequencies than in the control population (NCBI, 1000 genome and housing-genome). This will allow us to identify genetic mutations of susceptibility to primary PE.
