NCT Number: NCT06280807
Background:
Endocrine disorders occur when the glands that make hormones do not work properly. Hormones levels that are too high or too low can cause problems such as late or early puberty, irregular periods, and infertility. Environmental factors - including pollution; chemical exposure at home and work; foods; medicines; and sleep habits - may cause problems with the endocrine and reproductive systems.
Objective:
To learn how environmental factors may affect the endocrine and reproductive systems.
Eligibility:
Males or females, referring to sex assigned at birth, aged 8 years and older; they must have hypogonadism, infertility, or other reproductive disorders.
Design:
Adult participants will have 4 to 5 visits in 5 years. Children may have up to 12 visits; they may remain in the study up to the age of 23. Most visits will be less than 3 hours.
Participants will be screened. They will have a physical exam. They will have blood and urine tests. They will complete questionnaires; they will answer questions about their diet, health, and other topics. Some may be referred for additional tests, such as imaging scans and semen analysis.
Specific tests conducted during study visits will vary, depending on the participant s diagnosis. In addition to repeated blood and urine tests, these may include:
Body composition measure: Participants will sit in a pod-shaped machine for about 6 minutes. The machines measures the air inside the capsule to record body fat and breathing volume.
Resting energy expenditure test: Participants will lie down with a clear dome placed over their head. They will breathe quietly for 30 minutes. This test measures the number of calories their body burns at rest.

Study Description:
This study will investigate the relationship between environment, lifestyle, and reproductive function. This will include the study of these factors at enrollment and in response to clinical care for the underlying condition. This study will prospectively follow participants with endocrine reproductive disorders and collect research data, data secondary to clinical care and data regarding internal and external environmental exposures. We hypothesize that dysregulated environment is associated with reproductive and endocrine symptoms and dysfunction, and the clinical phenotype may evolve in response to treatment of the dysfunction.
Objectives:
Endpoints:
Since this is an exploratory and hypothesis generating study there are no pre-defined endpoints of this study.
Healthy volunteers accepted: No
Only the study team can determine whether someone qualifies for participation.
In order to be eligible to participate in this study, an individual must meet all of the following criteria:
Some specific diagnoses (as defined in standard guidelines) will include:
or
--Exhibiting signs of a diagnosis of hypogonadism, e.g., Bosma arrhinia microphthalmia syndrome (BAMS)
-Ability of participant, legal guardian, or Legally Authorized Representative (LAR) to understand and the willingness to sign a written informed consent document.
Exclusion criteria
An individual who meets any of the following criteria will be excluded from participation in this study:
Individuals who do not meet the criteria for participation in this study (screen failure) because of an acute, reversible or transient medical reason may be rescreened upon reversal, improvement or stabilization of their clinical status. Participants who develop an acute, reversible or transient medical condition during the study may return upon reversal, improvement or stabilization of their clinical status.

Inclusion criteria
Exclusion criteria
Specific wash-out periods are required for evaluation of diagnosis or for exclusionary medications or supplements.
Time frame: at baseline and after clinical care for the underlying condition
We will analyze the correlation between internal exposures, and the longitudinal evolution of endocrine disorders. For instance, changes in PSQI (sleep) and DSM-5 (mood) questionnaire scores, research analytes and hormone metrics with treatment.
Time frame: at baseline and after clinical care for the underlying condition
We will analyze the correlation between external exposures, and the longitudinal evolution of endocrine disorders. For instance, we will assess for changes in (stress), eating disorders and exposome information (derived from co-enrollment in the PEGS study) before and after treatment.
